Ignaz Semmelweis investigated puerperal fever and he discovered how it was caused. He noticed that the frequently fatal fever occurred more often in mothers examined by medical students than by midwives. The students went from the dissecting room to the hospital ward and examined women in childbirth. Semmelweis showed that when the trainees washed their hands in chlorinated lime before each clinical examination, the incidence of puerperal fever among the mothers could be reduced dramatically. Before the modern medical era, the main means for studying the internal structures of the body were dissection of the dead and inspection, palpation and auscultation of the living. It was the advent of microscopy that opened up an understanding of the building blocks that constituted living tissues. Technical advances in the development of achromatic lenses increased the resolving power of the microscope and around 1839, Matthias Jakob Schleiden and Theodor Schwann identified that cells were the fundamental unit of organization of all living things. Study of small structures involved passing light through them and the microtome was invented to provide sufficiently thin slices of tissue to examine. Staining techniques using artificial dyes were established to help distinguish between different types of tissue. Advances in the fields of histology and cytology began in the late 19th century along with advances in surgical techniques allowing for the painless and safe removal of biopsy specimens. The invention of the electron microscope brought a great advance in resolution power and allowed research into the ultrastructure of cells and the organelles and other structures within them. About the same time, in the 1950s, the use of X-ray diffraction for studying the crystal structures of proteins, nucleic acids and other biological molecules gave rise to a new field of molecular anatomy. Equally important advances have occurred in non-invasive techniques for examining the interior structures of the body. X-rays can be passed through the body and used in medical radiography and fluoroscopy to differentiate interior structures that have varying degrees of opaqueness. Magnetic resonance imaging, computed tomography, and ultrasound imaging have all enabled examination of internal structures in unprecedented detail to a degree far beyond the imagination of earlier generations.

Affirming the consequent Affirming the consequent, sometimes called converse error, fallacy of the converse, or confusion of necessity and sufficiency, is a formal fallacy of taking a true conditional statement (e.g., "If the lamp were broken, then the room would be dark"), and invalidly inferring its converse ("The room is dark, so the lamp is broken"), even though the converse may not be true. This arises when a consequent ("the room would be dark") has more than one other possible antecedent (for example, "the lamp is not plugged in" or "the lamp is in working order, but is switched off"). Converse errors are common in everyday thinking and communication and can result from, among other causes, communication issues, misconceptions about logic, and failure to consider other causes. The opposite statement, denying the consequent, is a valid form of argument. Formal description Affirming the consequent is the action of taking a true statement and invalidly concluding its converse . The name affirming the consequent derives from using the consequent, Q, of , to conclude the antecedent P. This illogic can be summarized formally as or, alternatively, . The root cause of such a logic error is sometimes failure to realize that just because P is a possible condition for Q, P may not be the only condition for Q, i.e. Q may follow from another condition as well. Affirming the consequent can also result from overgeneralizing the experience of many statements having true converses. If P and Q are "equivalent" statements, i.e. , it is possible to infer P under the condition Q. For example, the statements "It is August 13, so it is my birthday" and "It is my birthday, so it is August 13" are equivalent and both true consequences of the statement "August 13 is my birthday" (an abbreviated form of ). Using one statement to conclude the other is not an example of affirming the consequent, but some people may misapply the approach. Additional examples Example 1 One way to demonstrate the invalidity of this argument form is with a counterexample with true premises but an obviously false conclusion. For example: If Bill Gates owns Fort Knox, then Bill Gates is rich. Bill Gates is rich. Therefore, Bill Gates owns Fort Knox. Owning Fort Knox is not the only way to be rich. Any number of other ways to be rich exist. However, one can affirm with certainty that "if someone is not rich" (non-Q), then "this person does not own Fort Knox" (non-P). This is the contrapositive of the first statement, and it must be true if and only if the original statement is true. Example 2 Here is another useful, obviously-fallacious example, but one that does not require familiarity with who Bill Gates is and what Fort Knox is: If an animal is a dog, then it has four legs. My cat has four legs. Therefore, my cat is a dog.

Here, it is immediately intuitive that any number of other antecedents ("If an animal is a deer...", "If an animal is an elephant...", "If an animal is a moose...", etc.) can give rise to the consequent ("then it has four legs"), and that it is preposterous to suppose that having four legs must imply that the animal is a dog and nothing else. This is useful as a teaching example since most people can immediately recognize that the conclusion reached must be wrong (intuitively, a cat cannot be a dog), and that the method by which it was reached must therefore be fallacious. Example 3 Arguments of the same form can sometimes seem superficially convincing, as in the following example: If Brian had been thrown off the top of the Eiffel Tower, then he would be dead. Brian is dead. Therefore, Brian was thrown off the top of the Eiffel Tower. Being thrown off the top of the Eiffel Tower is not the only cause of death, since there exist numerous different causes of death. Affirming the consequent is commonly used in rationalization, and thus appears as a coping mechanism in some people. Example 4 In Catch-22, the chaplain is interrogated for supposedly being "Washington Irving"/"Irving Washington", who has been blocking out large portions of soldiers' letters home. The colonel has found such a letter, but with the Chaplain's name signed. "You can read, though, can't you?" the colonel persevered sarcastically. "The author signed his name." "That's my name there." "Then you wrote it. Q.E.D." P in this case is 'The chaplain signs his own name', and Q 'The chaplain's name is written'.

Andrei Tarkovsky Andrei Arsenyevich Tarkovsky (; 4 April 1932 – 29 December 1986) was a Russian film director, screenwriter, and film theorist. He is widely regarded as one of the greatest and most influential filmmakers in Russian and world cinema. His films explored spiritual and metaphysical themes, and are noted for their slow pacing and long takes, dreamlike visual imagery, and preoccupation with nature and memory. Tarkovsky studied film at Moscow's VGIK under filmmaker Mikhail Romm, and subsequently directed his first five features in the Soviet Union: Ivan's Childhood (1962), Andrei Rublev (1966), Solaris (1972), Mirror (1975), and Stalker (1979). A number of his films from this period are ranked among the best films ever made. After years of creative conflict with state film authorities, Tarkovsky left the country in 1979 and made his final two films abroad; Nostalghia (1983) and The Sacrifice (1986) were produced in Italy and Sweden respectively. In 1986, he also published a book about cinema and art entitled Sculpting in Time. He died of cancer later that year. Tarkovsky was the recipient of several awards at the Cannes Film Festival throughout his career (including the FIPRESCI prize, the Prize of the Ecumenical Jury, and the Grand Prix Spécial du Jury) and winner of the Golden Lion award at the Venice Film Festival for his debut film Ivan's Childhood. In 1990, he was posthumously awarded the Soviet Union's prestigious Lenin Prize. Three of his films—Andrei Rublev, Mirror, and Stalker—featured in Sight & Sounds 2012 poll of the 100 greatest films of all time. Life and career Childhood and early life Andrei Tarkovsky was born in the village of Zavrazhye in the Yuryevetsky District of the Ivanovo Industrial Oblast (modern-day Kadyysky District of the Kostroma Oblast, Russia) to the poet and translator Arseny Alexandrovich Tarkovsky, a native of Kropyvnytskyi, Ukraine, and Maria Ivanova Vishnyakova, a graduate of the Maxim Gorky Literature Institute who later worked as a corrector; she was born in Moscow in the Dubasov family estate. Andrei's paternal grandfather Aleksandr Karlovich Tarkovsky (in ) was a Polish nobleman who worked as a bank clerk. His wife Maria Danilovna Rachkovskaya was a Romanian teacher who arrived from Iași. Andrei's maternal grandmother Vera Nikolaevna Vishnyakova (née Dubasova) belonged to an old Dubasov family of Russian nobility that traces its history back to the 17th century; among her relatives was Admiral Fyodor Dubasov, a fact she had to conceal during the Soviet days. She was married to Ivan Ivanovich Vishnyakov, a native of the Kaluga Governorate who studied law at the Moscow State University and served as a judge in Kozelsk. from the Brockhaus and Efron Encyclopedic Dictionary, 1890–1907 (Wikisource, in Russian) According to the family legend, Tarkovsky's ancestors on his father's side were princes from the Shamkhalate of Tarki, Dagestan, although his sister Marina Tarkovskaya who did a detailed research on their genealogy called it "a myth, even a prank of sorts," stressing that none of the documents confirms this version.

Tarkovsky spent his childhood in Yuryevets.

He was described by childhood friends as active and popular, having many friends and being typically in the center of action. His father left the family in 1937, subsequently volunteering for the army in 1941. He returned home in 1943, having been awarded a Red Star after being shot in one of his legs (which he would eventually need to amputate due to gangrene). Tarkovsky stayed with his mother, moving with her and his sister Marina to Moscow, where she worked as a proofreader at a printing press. In 1939, Tarkovsky enrolled at the Moscow School No. 554. During the war, the three evacuated to Yuryevets, living with his maternal grandmother. In 1943, the family returned to Moscow. Tarkovsky continued his studies at his old school, where the poet Andrei Voznesensky was one of his classmates. He studied piano at a music school and attended classes at an art school. The family lived on Shchipok Street in the Zamoskvorechye District in Moscow. From November 1947 to spring 1948 he was in the hospital with tuberculosis. Many themes of his childhood—the evacuation, his mother and her two children, the withdrawn father, the time in the hospital—feature prominently in his film Mirror. In his school years, Tarkovsky was a troublemaker and a poor student. He still managed to graduate, and from 1951 to 1952 studied Arabic at the Oriental Institute in Moscow, a branch of the Academy of Sciences of the Soviet Union. Although he already spoke some Arabic and was a successful student in his first semesters, he did not finish his studies and dropped out to work as a prospector for the Academy of Science Institute for Non-Ferrous Metals and Gold. He participated in a year-long research expedition to the river Kureyka near Turukhansk in the Krasnoyarsk Province. During this time in the taiga, Tarkovsky decided to study film. Film school student Upon returning from the research expedition in 1954, Tarkovsky applied at the State Institute of Cinematography (VGIK) and was admitted to the film-directing program. He was in the same class as Irma Raush (Irina) whom he married in April 1957. The early Khrushchev era offered good opportunities for young film directors. Before 1953, annual film production was low and most films were directed by veteran directors. After 1953, more films were produced, many of them by young directors. The Khrushchev Thaw relaxed Soviet social restrictions a bit and permitted a limited influx of European and North American literature, films and music. This allowed Tarkovsky to see films of the Italian neorealists, French New Wave, and of directors such as Kurosawa, Buñuel, Bergman, Bresson, Wajda (whose film Ashes and Diamonds influenced Tarkovsky) and Mizoguchi. Tarkovsky's teacher and mentor was Mikhail Romm, who taught many film students who would later become influential film directors. In 1956, Tarkovsky directed his first student short film, The Killers, from a short story of Ernest Hemingway. The longer television film There Will Be No Leave Today followed in 1959.

In 1956, Tarkovsky directed his first student short film, The Killers, from a short story of Ernest Hemingway. The longer television film There Will Be No Leave Today followed in 1959.

Both films were a collaboration between the VGIK students. Classmate Aleksandr Gordon, who married Tarkovsky's sister, in particular directed, wrote, edited, and acted in the two films with Tarkovsky. An important influence on Tarkovsky was the film director Grigory Chukhray, who was teaching at the VGIK. Impressed by the talent of his student, Chukhray offered Tarkovsky a position as assistant director for his film Clear Skies. Tarkovsky initially showed interest but then decided to concentrate on his studies and his own projects. During his third year at the VGIK, Tarkovsky met Andrei Konchalovsky. They found much in common as they liked the same film directors and shared ideas on cinema and films. In 1959, they wrote the script Antarctica – Distant Country, which was later published in the Moskovsky Komsomolets. Tarkovsky submitted the script to Lenfilm, but it was rejected. They were more successful with the script The Steamroller and the Violin, which they sold to Mosfilm. This became Tarkovsky's graduation project, earning him his diploma in 1960 and winning First Prize at the New York Student Film Festival in 1961. Film career in the Soviet Union Tarkovsky's first feature film was Ivan's Childhood in 1962. He had inherited the film from director Eduard Abalov, who had to abort the project. The film earned Tarkovsky international acclaim and won the Golden Lion award at the Venice Film Festival in the year 1962. In the same year, on 30 September, his first son Arseny (called Senka in Tarkovsky's diaries) Tarkovsky was born. In 1965, he directed the film Andrei Rublev about the life of Andrei Rublev, the fifteenth-century Russian icon painter. Andrei Rublev was not, except for a single screening in Moscow in 1966, immediately released after completion due to problems with Soviet authorities. Tarkovsky had to cut the film several times, resulting in several different versions of varying lengths. The film was widely released in the Soviet Union in a cut version in 1971. Nevertheless, the film had a budget of more than 1 million rubles – a significant sum for that period. A version of the film was presented at the Cannes Film Festival in 1969 and won the FIPRESCI prize. He divorced his wife, Irina, in June 1970. In the same year, he married Larisa Kizilova (née Egorkina), who had been a production assistant for the film Andrei Rublev (they had been living together since 1965). Their son, Andrei Andreyevich Tarkovsky, (nicknamed Andriosha, meaning "little Andre" or "Andre Junior") was born in the same year on 7 August. In 1972, he completed Solaris, an adaptation of the novel Solaris by Stanisław Lem. He had worked on this together with screenwriter Friedrich Gorenstein as early as 1968. The film was presented at the Cannes Film Festival, won the Grand Prix Spécial du Jury, and was nominated for the Palme d'Or. From 1973 to 1974, he shot the film Mirror, a highly autobiographical and unconventionally structured film drawing on his childhood and incorporating some of his father's poems.

Both films were a collaboration between the VGIK students. Classmate Aleksandr Gordon, who married Tarkovsky's sister, in particular directed, wrote, edited, and acted in the two films with Tarkovsky. An important influence on Tarkovsky was the film director Grigory Chukhray, who was teaching at the VGIK. Impressed by the talent of his student, Chukhray offered Tarkovsky a position as assistant director for his film Clear Skies. Tarkovsky initially showed interest but then decided to concentrate on his studies and his own projects. During his third year at the VGIK, Tarkovsky met Andrei Konchalovsky. They found much in common as they liked the same film directors and shared ideas on cinema and films. In 1959, they wrote the script Antarctica – Distant Country, which was later published in the Moskovsky Komsomolets. Tarkovsky submitted the script to Lenfilm, but it was rejected. They were more successful with the script The Steamroller and the Violin, which they sold to Mosfilm. This became Tarkovsky's graduation project, earning him his diploma in 1960 and winning First Prize at the New York Student Film Festival in 1961. Film career in the Soviet Union Tarkovsky's first feature film was Ivan's Childhood in 1962. He had inherited the film from director Eduard Abalov, who had to abort the project. The film earned Tarkovsky international acclaim and won the Golden Lion award at the Venice Film Festival in the year 1962. In the same year, on 30 September, his first son Arseny (called Senka in Tarkovsky's diaries) Tarkovsky was born. In 1965, he directed the film Andrei Rublev about the life of Andrei Rublev, the fifteenth-century Russian icon painter. Andrei Rublev was not, except for a single screening in Moscow in 1966, immediately released after completion due to problems with Soviet authorities. Tarkovsky had to cut the film several times, resulting in several different versions of varying lengths. The film was widely released in the Soviet Union in a cut version in 1971. Nevertheless, the film had a budget of more than 1 million rubles – a significant sum for that period. A version of the film was presented at the Cannes Film Festival in 1969 and won the FIPRESCI prize. He divorced his wife, Irina, in June 1970.

From 1973 to 1974, he shot the film Mirror, a highly autobiographical and unconventionally structured film drawing on his childhood and incorporating some of his father's poems.

In this film Tarkovsky portrayed the plight of childhood affected by war. Tarkovsky had worked on the screenplay for this film since 1967, under the consecutive titles Confession, White day and A white, white day. From the beginning the film was not well received by Soviet authorities due to its content and its perceived elitist nature. Soviet authorities placed the film in the "third category", a severely limited distribution, and only allowed it to be shown in third-class cinemas and workers' clubs. Few prints were made and the film-makers received no returns. Third category films also placed the film-makers in danger of being accused of wasting public funds, which could have serious effects on their future productivity. These difficulties are presumed to have made Tarkovsky play with the idea of going abroad and producing a film outside the Soviet film industry. During 1975, Tarkovsky also worked on the screenplay Hoffmanniana, about the German writer and poet E. T. A. Hoffmann. In December 1976, he directed Hamlet, his only stage play, at the Lenkom Theatre in Moscow. The main role was played by Anatoly Solonitsyn, who also acted in several of Tarkovsky's films. At the end of 1978, he also wrote the screenplay Sardor together with the writer Aleksandr Misharin. The last film Tarkovsky completed in the Soviet Union was Stalker, inspired by the novel Roadside Picnic by the brothers Arkady and Boris Strugatsky. Tarkovsky had met the brothers first in 1971 and was in contact with them until his death in 1986. Initially he wanted to shoot a film based on their novel Dead Mountaineer's Hotel and he developed a raw script. Influenced by a discussion with Arkady Strugatsky he changed his plan and began to work on the script based on Roadside Picnic. Work on this film began in 1976. The production was mired in troubles; improper development of the negatives had ruined all the exterior shots. Tarkovsky's relationship with cinematographer Georgy Rerberg deteriorated to the point where he hired Alexander Knyazhinsky as a new first cinematographer. Furthermore, Tarkovsky suffered a heart attack in April 1978, resulting in further delay. The film was completed in 1979 and won the Prize of the Ecumenical Jury at the Cannes Film Festival. In a question and answer session at the Edinburgh Filmhouse on 11 February 1981, Tarkovsky trenchantly rejected suggestions that the film was either impenetrably mysterious or a political allegory. In 1979, Tarkovsky began production of the film The First Day (Russian: Первый День Pervyj Dyen), based on a script by his friend and long-term collaborator Andrei Konchalovsky. The film was set in 18th-century Russia during the reign of Peter the Great and starred Natalya Bondarchuk and Anatoli Papanov. To get the project approved by Goskino, Tarkovsky submitted a script that was different from the original script, omitting several scenes that were critical of the official atheism in the Soviet Union.

To get the project approved by Goskino, Tarkovsky submitted a script that was different from the original script, omitting several scenes that were critical of the official atheism in the Soviet Union.

After shooting roughly half of the film the project was stopped by Goskino after it became apparent that the film differed from the script submitted to the censors. Tarkovsky was reportedly infuriated by this interruption and destroyed most of the film. Film career outside the Soviet Union During the summer of 1979, Tarkovsky traveled to Italy, where he shot the documentary Voyage in Time together with his long-time friend Tonino Guerra. Tarkovsky returned to Italy in 1980 for an extended trip, during which he and Guerra completed the script for the film Nostalghia. During this period, he took Polaroid photographs depicting his personal life. Tarkovsky returned to Italy in 1982 to start shooting Nostalghia, but Mosfilm then withdrew from the project, so he sought and received financial backing from the Italian RAI. Tarkovsky completed the film in 1983, and it was presented at the Cannes Film Festival where it won the FIPRESCI prize and the Prize of the Ecumenical Jury. Tarkovsky also shared a special prize called Grand Prix du cinéma de creation with Robert Bresson. Soviet authorities lobbied to prevent the film from winning the Palme d'Or, a fact that hardened Tarkovsky's resolve to never work in the Soviet Union again. After Cannes he went to London to stage and choreograph the opera Boris Godunov at the Royal Opera House under the musical direction of Claudio Abbado. At a press conference in Milan on 10 July 1984, he announced that he would never return to the Soviet Union and would remain in Western Europe. He stated, "I am not a Soviet dissident, I have no conflict with the Soviet Government," but if he returned home, he added, "I would be unemployed." At that time, his son Andriosha was still in the Soviet Union and not allowed to leave the country. On 28 August 1985, Tarkovsky was processed as a Soviet Defector at a refugee camp in Latina, Italy, registered with the serial number 13225/379, and officially welcomed to the West. Tarkovsky spent most of 1984 preparing the film The Sacrifice. It was finally shot in 1985 in Sweden, with many of the crew being alumni from Ingmar Bergman's films, including cinematographer Sven Nykvist. Tarkovsky's vision of his film was greatly influenced by Bergman's style. While The Sacrifice is about an apocalypse and impending death, faith, and possible redemption, in the making-of documentary Directed by Andrei Tarkovsky, in a particularly poignant scene, writer/director Michal Leszczylowski follows Tarkovsky on a walk as he expresses his sentiments on death — he claims himself to be immortal and has no fear of dying. Ironically, at the end of the year Tarkovsky was diagnosed with terminal lung cancer. In January 1986, he began treatment in Paris and was joined there by his son, Andre Jr, who was finally allowed to leave the Soviet Union. What would be Tarkovsky's final film was dedicated to him.

The Sacrifice was presented at the Cannes Film Festival and received the Grand Prix Spécial du Jury, the FIPRESCI prize and the Prize of the Ecumenical Jury. As Tarkovsky was unable to attend due to his illness, the prizes were collected by his son. Death In Tarkovsky's last diary entry (15 December 1986), he wrote: "But now I have no strength left — that is the problem". The diaries are sometimes also known as Martyrology and were published posthumously in 1989 and in English in 1991. Tarkovsky died in Paris on 29 December 1986. His funeral ceremony was held at the Alexander Nevsky Cathedral. He was buried on 3 January 1987 in the Russian Cemetery in Sainte-Geneviève-des-Bois in France. The inscription on his gravestone, which was erected in 1994, was conceived by Tarkovsky's wife, Larisa, reads: To the man who saw the Angel. Larisa died in 1998 and is buried beside her husband. A conspiracy theory emerged in Russia in the early 1990s when it was alleged that Tarkovsky did not die of natural causes, but was assassinated by the KGB. Evidence for this hypothesis includes testimonies by former KGB agents who claim that Viktor Chebrikov gave the order to eradicate Tarkovsky to curtail what the Soviet government and the KGB saw as anti-Soviet propaganda by Tarkovsky. Other evidence includes several memoranda that surfaced after the 1991 coup and the claim by one of Tarkovsky's doctors that his cancer could not have developed from a natural cause. As with Tarkovsky, his wife Larisa and actor Anatoly Solonitsyn all died from the very same type of lung cancer. Vladimir Sharun, sound designer in Stalker, is convinced that they were all poisoned by the chemical plant where they were shooting the film. Influences Tarkovsky became a film director during the mid and late 1950s, a period referred to as the Khrushchev Thaw, during which Soviet society opened to foreign films, literature and music, among other things. This allowed Tarkovsky to see films of European, American and Japanese directors, an experience that influenced his own film making. His teacher and mentor at the film school, Mikhail Romm, allowed his students considerable freedom and emphasized the independence of the film director. Tarkovsky was, according to fellow student Shavkat Abdusalmov, fascinated by Japanese films. He was amazed by how every character on the screen is exceptional and how everyday events such as a Samurai cutting bread with his sword are elevated to something special and put into the limelight. Tarkovsky has also expressed interest in the art of Haiku and its ability to create "images in such a way that they mean nothing beyond themselves". Tarkovsky was also a deeply religious Orthodox Christian, who believed great art should have a higher spiritual purpose. He was a perfectionist not given to humor or humility: his signature style was ponderous and literary, having many characters that pondered over religious themes and issues regarding faith.

Tarkovsky perceived that the art of cinema has only been truly mastered by very few filmmakers, stating in a 1970 interview with Naum Abramov that "they can be counted on the fingers of one hand". In 1972, Tarkovsky told film historian Leonid Kozlov his ten favorite films. The list includes: Diary of a Country Priest and Mouchette by Robert Bresson; Winter Light, Wild Strawberries, and Persona by Ingmar Bergman; Nazarín by Luis Buñuel; City Lights by Charlie Chaplin; Ugetsu by Kenji Mizoguchi; Seven Samurai by Akira Kurosawa, and Woman in the Dunes by Hiroshi Teshigahara. Among his favorite directors were Buñuel, Mizoguchi, Bergman, Bresson, Kurosawa, Michelangelo Antonioni, Jean Vigo, and Carl Theodor Dreyer. With the exception of City Lights, the list does not contain any films of the early silent era. The reason is that Tarkovsky saw film as an art as only a relatively recent phenomenon, with the early film-making forming only a prelude. The list has also no films or directors from Tarkovsky's native Russia, although he rated Soviet directors such as Boris Barnet, Sergei Parajanov and Alexander Dovzhenko highly. He said of Dovzhenko's Earth: "I have lived a lot among very simple farmers and met extraordinary people. They spread calmness, had such tact, they conveyed a feeling of dignity and displayed wisdom that I have seldom come across on such a scale. Dovzhenko had obviously understood wherein the sense of life resides. [...] This trespassing of the border between nature and mankind is an ideal place for the existence of man. Dovzhenko understood this." Andrei Tarkovsky was not a fan of science fiction, largely dismissing it for its "comic book" trappings and vulgar commercialism. However, in a famous exception Tarkovsky praised the blockbuster film The Terminator, saying that its "vision of the future and the relation between man and its destiny is pushing the frontier of cinema as an art". He was critical of the "brutality and low acting skills", but was nevertheless impressed by the film. Cinematic style In a 1962 interview, Tarkovsky argued: "All art, of course, is intellectual, but for me, all the arts, and cinema even more so, must above all be emotional and act upon the heart." His films are characterized by metaphysical themes, extremely long takes, and images often considered by critics to be of exceptional beauty. Recurring motifs are dreams, memory, childhood, running water accompanied by fire, rain indoors, reflections, levitation, and characters re-appearing in the foreground of long panning movements of the camera. He once said: "Juxtaposing a person with an environment that is boundless, collating him with a countless number of people passing by close to him and far away, relating a person to the whole world, that is the meaning of cinema." Tarkovsky incorporated levitation scenes into several of his films, most notably Solaris. To him these scenes possess great power and are used for their photogenic value and magical inexplicability.

Tarkovsky perceived that the art of cinema has only been truly mastered by very few filmmakers, stating in a 1970 interview with Naum Abramov that "they can be counted on the fingers of one hand". In 1972, Tarkovsky told film historian Leonid Kozlov his ten favorite films. The list includes: Diary of a Country Priest and Mouchette by Robert Bresson; Winter Light, Wild Strawberries, and Persona by Ingmar Bergman; Nazarín by Luis Buñuel; City Lights by Charlie Chaplin; Ugetsu by Kenji Mizoguchi; Seven Samurai by Akira Kurosawa, and Woman in the Dunes by Hiroshi Teshigahara.

Tarkovsky incorporated levitation scenes into several of his films, most notably Solaris. To him these scenes possess great power and are used for their photogenic value and magical inexplicability.

Water, clouds, and reflections were used by him for their surreal beauty and photogenic value, as well as their symbolism, such as waves or the forms of brooks or running water. Bells and candles are also frequent symbols. These are symbols of film, sight and sound, and Tarkovsky's film frequently has themes of self-reflection. Tarkovsky developed a theory of cinema that he called "sculpting in time". By this he meant that the unique characteristic of cinema as a medium was to take our experience of time and alter it. Unedited movie footage transcribes time in real time. By using long takes and few cuts in his films, he aimed to give the viewers a sense of time passing, time lost, and the relationship of one moment in time to another. Up to, and including, his film Mirror, Tarkovsky focused his cinematic works on exploring this theory. After Mirror, he announced that he would focus his work on exploring the dramatic unities proposed by Aristotle: a concentrated action, happening in one place, within the span of a single day. Several of Tarkovsky's films have color or black-and-white sequences. This first occurs in the otherwise monochrome Andrei Rublev, which features a color epilogue of Rublev's authentic religious icon paintings. All of his films afterwards contain monochrome, and in Stalker's case sepia sequences, while otherwise being in color. In 1966, in an interview conducted shortly after finishing Andrei Rublev, Tarkovsky dismissed color film as a "commercial gimmick" and cast doubt on the idea that contemporary films meaningfully use color. He claimed that in everyday life one does not consciously notice colors most of the time, and that color should therefore be used in film mainly to emphasize certain moments, but not all the time, as this distracts the viewer. To him, films in color were like moving paintings or photographs, which are too beautiful to be a realistic depiction of life. Bergman on Tarkovsky Ingmar Bergman, a renowned director, commented on Tarkovsky: Contrarily, however, Bergman conceded the truth in the claim made by a critic who wrote that "with Autumn Sonata Bergman does Bergman", adding: "Tarkovsky began to make Tarkovsky films, and that Fellini began to make Fellini films [...] Buñuel nearly always made Buñuel films." This pastiche of one's own work has been derogatorily termed as "self-karaoke". Vadim Yusov Tarkovsky worked in close collaboration with cinematographer Vadim Yusov from 1958 to 1972, and much of the visual style of Tarkovsky's films can be attributed to this collaboration. Tarkovsky would spend two days preparing for Yusov to film a single long take, and due to the preparation, usually only a single take was needed. Sven Nykvist In his last film, The Sacrifice, Tarkovsky worked with cinematographer Sven Nykvist, who had worked on many films with director Ingmar Bergman. (Nykvist was not alone: several people involved in the production had previously collaborated with Bergman, notably lead actor Erland Josephson, who had also acted for Tarkovsky in Nostalghia.)

(Nykvist was not alone: several people involved in the production had previously collaborated with Bergman, notably lead actor Erland Josephson, who had also acted for Tarkovsky in Nostalghia.)

Nykvist complained that Tarkovsky would frequently look through the camera and even direct actors through it, but ultimately stated that choosing to work with Tarkovsky was one of the best choices he had ever made. Personal life Sexuality Film scholars Vita T. Johnson and Graham Petrie, in The Films of Andrei Tarkovsky: A Visual Fugue (1994), wrote that Tarkovsky was bisexual and speculated more controversially that he was also ephebophilic. Noting that Tarkovsky's favorite hair color was red, they argue that his work portrays female sexuality negatively except in the case of a sexually precocious red-haired child in Mirror who is also played by his own red-haired step-daughter. Film teacher David Pratt criticized the evidence given for the theory as insufficient. Dina Iordanova likewise found the claim on bisexuality too undeveloped. Donato Totaro, however, took this claim seriously and said that "perhaps the authors were 'protecting' their source, given that homosexuality is still a taboo subject in Russia." Filmography Tarkovsky is mainly known as a film director. During his career he directed seven feature films, as well as three shorts from his time at VGIK. His features are: Ivan's Childhood (1962) Andrei Rublev (1966) Solaris (1972) Mirror (1975) Stalker (1979) Nostalghia (1983) The Sacrifice (1986) He also wrote several screenplays. Furthermore, he directed the play Hamlet for the stage in Moscow, directed the opera Boris Godunov in London, and he directed a radio production of the short story Turnabout by William Faulkner. He also wrote Sculpting in Time, a book on film theory. Tarkovsky's first feature film was Ivan's Childhood in 1962. He then directed Andrei Rublev in 1966, Solaris in 1972, Mirror in 1975 and Stalker in 1979. The documentary Voyage in Time was produced in Italy in 1982, as was Nostalghia in 1983. His last film The Sacrifice was produced in Sweden in 1986. Tarkovsky was personally involved in writing the screenplays for all his films, sometimes with a cowriter. Tarkovsky once said that a director who realizes somebody else's screenplay without being involved in it becomes a mere illustrator, resulting in dead and monotonous films. Published books Sculpting in Time, published in 1986 Time Within Time: The Diaries 1970–1986, published in 1989 A book of 60 photos, Instant Light, Tarkovsky Polaroids, taken by Tarkovsky in Russia and Italy between 1979 and 1984 was published in 2006. The collection was selected by Italian photographer Giovanni Chiaramonte and Tarkovsky's son Andrey A. Tarkovsky. Unproduced screenplays ConcentrateConcentrate (, Kontsentrat) is a never-filmed 1958 screenplay by Tarkovsky. The screenplay is based on Tarkovsky's year in the taiga as a member of a research expedition, prior to his enrollment in film school. It's about the leader of a geological expedition, who waits for the boat that brings back the concentrates collected by the expedition. The expedition is surrounded by mystery, and its purpose is a state secret.

Although some authors claim that the screenplay was filmed, according to Marina Tarkovskaya, Tarkovsky's sister (and wife of Aleksandr Gordon, a fellow student of Tarkovsky during his film school years) the screenplay was never filmed. Tarkovsky wrote the screenplay during his entrance examination at the State Institute of Cinematography (VGIK) in a single sitting. He earned the highest possible grade, "excellent" () for this work. In 1994, fragments of Concentrate were filmed and used in the documentary Andrei Tarkovsky's Taiga Summer by Marina Tarkovskaya and Aleksandr Gordon. HoffmannianaHoffmanniana () is a never-filmed 1974 screenplay by Tarkovsky. The screenplay is based on the life and work of German author E. T. A. Hoffmann. In 1974, an acquaintance from Tallinnfilm approached Tarkovsky to write a screenplay on a German theme. Tarkovsky considered Thomas Mann and E. T. A. Hoffmann, and also thought about Ibsen's Peer Gynt. In the end Tarkovsky signed a contract for a script based on the life and work of Hoffmann. He planned to write the script during the summer of 1974 at his dacha. Writing was not without difficulty, less than a month before the deadline he had not written a single page. He finally finished the project in late 1974 and submitted the final script to Tallinnfilm in October. Although the script was well received by the officials at Tallinnfilm, it was the consensus that no one but Tarkovsky would be able to direct it. The script was sent to Goskino in February 1976, and although approval was granted for proceeding with making the film, the screenplay was never realized. In 1984, during the time of his exile in the West, Tarkovsky revisited the screenplay and made a few changes. He also considered to finally direct a film based on the screenplay but ultimately dropped this idea.

After his death, an entire issue of the film magazine Iskusstvo Kino was devoted to Tarkovsky. In their obituaries, the film committee of the Council of Ministers of the Soviet Union and the Union of Soviet Film Makers expressed their sorrow that Tarkovsky had to spend the last years of his life in exile. Posthumously, he was awarded the Lenin Prize in 1990, one of the highest state honors in the Soviet Union. In 1989, the Andrei Tarkovsky Memorial Prize was established, with its first recipient being the Russian animator Yuri Norstein. In three consecutive events, the Moscow International Film Festival awarded the Andrei Tarkovsky Award in 1993, 1995, and 1997. In 1996, the Andrei Tarkovsky Museum opened in Yuryevets, his childhood town. A minor planet, 3345 Tarkovskij, discovered by Soviet astronomer Lyudmila Karachkina in 1982, has been named after him. Tarkovsky has been the subject of several documentaries. Most notable is the 1988 documentary Moscow Elegy, by Russian film director Alexander Sokurov. Sokurov's own work has been heavily influenced by Tarkovsky. The film consists mostly of narration over stock footage from Tarkovsky's films.

Film director Chris Marker produced the television documentary One Day in the Life of Andrei Arsenevich as an homage to Andrei Tarkovsky in 2000. At the entrance to the Gerasimov Institute of Cinematography in Moscow, there is a monument that includes statues of Tarkovsky, Gennady Shpalikov and Vasily Shukshin. Reception and influence on others Andrei Tarkovsky and his works have received praise from many filmmakers, critics and thinkers. The Swedish filmmaker Ingmar Bergman was quoted as saying: "Tarkovsky for me is the greatest [of us all], the one who invented a new language, true to the nature of film, as it captures life as a reflection, life as a dream". The Japanese filmmaker Akira Kurosawa remarked on Tarkovsky's films as saying: "His unusual sensitivity is both overwhelming and astounding. It almost reaches a pathological intensity. Probably there is no equal among film directors alive now." Kurosawa also commented: "I love all of Tarkovsky's films. I love his personality and all his works. Every cut from his films is a marvelous image in itself.

Every cut from his films is a marvelous image in itself.

But the finished image is nothing more than the imperfect accomplishment of his idea. His ideas are only realized in part. And he had to make do with it." The Iranian filmmaker Abbas Kiarostami remarked that: "Tarkovsky's works separate me completely from physical life, and are the most spiritual films I have seen". The Polish filmmaker Krzysztof Kieślowski commented that: "Andrei Tarkovsky was one of the greatest directors of recent years," and regarded Tarkovsky's film, Ivan's Childhood as an influence on his own work. The Armenian filmmaker Sergei Paradjanov remarked that watching Tarkovsky's film, Ivan's Childhood was his main inspiration to become a filmmaker by saying: "I did not know how to do anything and I would not have done anything if there had not been Ivan's Childhood". The Austrian filmmaker Michael Haneke voted for Mirror on his top 10 films in the 2002 Sight & Sound directors' poll and later said that he has seen the picture at least 25 times. The German filmmaker Wim Wenders dedicated his film Wings of Desire to Tarkovsky (along with François Truffaut and Yasujirō Ozu). The French filmmaker Chris Marker directed a documentary film as a homage to Tarkovsky called One Day in the Life of Andrei Arsenevich and used Tarkovsky's concept of "The Zone" (from the film, Stalker) for his film, Sans Soleil. The Greek filmmaker Theo Angelopoulos regarded Tarkokvsky's film Stalker as one of the films that influenced him. The Greek-Australian filmmaker Alex Proyas was "extremely influenced" by Tarkovsky's work and cited Stalker as one his favorite films. The French philosopher Jean-Paul Sartre highly praised Tarkovsky's film Ivan's Childhood, saying that it was one of the most beautiful films he had ever seen. The Japanese filmmaker Mamoru Oshii, known for his works such as Ghost in the Shell was influenced by Tarkovsky. The Indian-born British American novelist Salman Rushdie praised Tarkovsky and his work Solaris by calling it a "a sci-fi masterpiece". Film historian Steven Dillon says that much of subsequent film was deeply influenced by the films of Tarkovsky. Mexican filmmaker Alejandro González Iñarritu is a huge fan of Tarkovsky. He once said in an interview: "Andrei Rublev is maybe my favorite film ever", and in another interview, he added: "I remember, the first time I saw a Tarkovsky film, I was shocked by it. I did not know what to do. I was shocked by it. I was fascinated, because suddenly I realized that film could have so many more layers to it than what I had imagined before". There are many direct references and hidden tributes to Tarkovsky's movies in Iñarritu's drama The Revenant. Danish film director Lars von Trier is a fervent admirer of Tarkovsky's. He dedicated his film Antichrist to him, and, while discussing it with critic David Jenkins, asked: “Have you seen Mirror? I was hypnotised! I’ve seen it 20 times. It’s the closest thing I’ve got to a religion – to me he is a god".

Ambiguity Ambiguity is a type of meaning in which a phrase, statement or resolution is not explicitly defined, making several interpretations plausible. A common aspect of ambiguity is uncertainty. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved according to a rule or process with a finite number of steps. (The ambi- part of the term reflects an idea of "two", as in "two meanings".) The concept of ambiguity is generally contrasted with vagueness. In ambiguity, specific and distinct interpretations are permitted (although some may not be immediately obvious), whereas with information that is vague, it is difficult to form any interpretation at the desired level of specificity. Linguistic forms Lexical ambiguity is contrasted with semantic ambiguity. The former represents a choice between a finite number of known and meaningful context-dependent interpretations. The latter represents a choice between any number of possible interpretations, none of which may have a standard agreed-upon meaning. This form of ambiguity is closely related to vagueness. Linguistic ambiguity can be a problem in law, because the interpretation of written documents and oral agreements is often of paramount importance. Lexical ambiguity The lexical ambiguity of a word or phrase pertains to its having more than one meaning in the language to which the word belongs. "Meaning" here refers to whatever should be captured by a good dictionary. For instance, the word "bank" has several distinct lexical definitions, including "financial institution" and "edge of a river". Or consider "apothecary". One could say "I bought herbs from the apothecary". This could mean one actually spoke to the apothecary (pharmacist) or went to the apothecary (pharmacy). The context in which an ambiguous word is used often makes it evident which of the meanings is intended. If, for instance, someone says "I buried $100 in the bank", most people would not think someone used a shovel to dig in the mud. However, some linguistic contexts do not provide sufficient information to disambiguate a used word. Lexical ambiguity can be addressed by algorithmic methods that automatically associate the appropriate meaning with a word in context, a task referred to as word sense disambiguation. The use of multi-defined words requires the author or speaker to clarify their context, and sometimes elaborate on their specific intended meaning (in which case, a less ambiguous term should have been used). The goal of clear concise communication is that the receiver(s) have no misunderstanding about what was meant to be conveyed. An exception to this could include a politician whose "weasel words" and obfuscation are necessary to gain support from multiple constituents with mutually exclusive conflicting desires from their candidate of choice. Ambiguity is a powerful tool of political science. More problematic are words whose senses express closely related concepts. "Good", for example, can mean "useful" or "functional" (That's a good hammer), "exemplary" (She's a good student), "pleasing" (This is good soup), "moral" (a good person versus the lesson to be learned from a story), "righteous", etc.

"I have a good daughter" is not clear about which sense is intended. The various ways to apply prefixes and suffixes can also create ambiguity ("unlockable" can mean "capable of being unlocked" or "impossible to lock"). Semantic and syntactic ambiguity Semantic ambiguity occurs when a word, phrase or sentence, taken out of context, has more than one interpretation. In "We saw her duck" (example due to Richard Nordquist), the words "her duck" can refer either to the person's bird (the noun "duck", modified by the possessive pronoun "her"), or to a motion she made (the verb "duck", the subject of which is the objective pronoun "her", object of the verb "saw"). Syntactic ambiguity arises when a sentence can have two (or more) different meanings because of the structure of the sentence—its syntax. This is often due to a modifying expression, such as a prepositional phrase, the application of which is unclear. "He ate the cookies on the couch", for example, could mean that he ate those cookies that were on the couch (as opposed to those that were on the table), or it could mean that he was sitting on the couch when he ate the cookies. "To get in, you will need an entrance fee of $10 or your voucher and your drivers' license." This could mean that you need EITHER ten dollars OR BOTH your voucher and your license. Or it could mean that you need your license AND you need EITHER ten dollars OR a voucher. Only rewriting the sentence, or placing appropriate punctuation can resolve a syntactic ambiguity. For the notion of, and theoretic results about, syntactic ambiguity in artificial, formal languages (such as computer programming languages), see Ambiguous grammar. Usually, semantic and syntactic ambiguity go hand in hand. The sentence "We saw her duck" is also syntactically ambiguous. Conversely, a sentence like "He ate the cookies on the couch" is also semantically ambiguous. Rarely, but occasionally, the different parsings of a syntactically ambiguous phrase result in the same meaning. For example, the command "Cook, cook!" can be parsed as "Cook (noun used as vocative), cook (imperative verb form)! ", but also as "Cook (imperative verb form), cook (noun used as vocative)!". It is more common that a syntactically unambiguous phrase has a semantic ambiguity; for example, the lexical ambiguity in "Your boss is a funny man" is purely semantic, leading to the response "Funny ha-ha or funny peculiar?" Spoken language can contain many more types of ambiguities which are called phonological ambiguities, where there is more than one way to compose a set of sounds into words. For example, "ice cream" and "I scream". Such ambiguity is generally resolved according to the context. A mishearing of such, based on incorrectly resolved ambiguity, is called a mondegreen.

"He ate the cookies on the couch", for example, could mean that he ate those cookies that were on the couch (as opposed to those that were on the table), or it could mean that he was sitting on the couch when he ate the cookies. "To get in, you will need an entrance fee of $10 or your voucher and your drivers' license." This could mean that you need EITHER ten dollars OR BOTH your voucher and your license. Or it could mean that you need your license AND you need EITHER ten dollars OR a voucher. Only rewriting the sentence, or placing appropriate punctuation can resolve a syntactic ambiguity. For the notion of, and theoretic results about, syntactic ambiguity in artificial, formal languages (such as computer programming languages), see Ambiguous grammar. Usually, semantic and syntactic ambiguity go hand in hand. The sentence "We saw her duck" is also syntactically ambiguous. Conversely, a sentence like "He ate the cookies on the couch" is also semantically ambiguous. Rarely, but occasionally, the different parsings of a syntactically ambiguous phrase result in the same meaning. For example, the command "Cook, cook!" can be parsed as "Cook (noun used as vocative), cook (imperative verb form)! ", but also as "Cook (imperative verb form), cook (noun used as vocative)!". It is more common that a syntactically unambiguous phrase has a semantic ambiguity; for example, the lexical ambiguity in "Your boss is a funny man" is purely semantic, leading to the response "Funny ha-ha or funny peculiar?" Spoken language can contain many more types of ambiguities which are called phonological ambiguities, where there is more than one way to compose a set of sounds into words. For example, "ice cream" and "I scream". Such ambiguity is generally resolved according to the context. A mishearing of such, based on incorrectly resolved ambiguity, is called a mondegreen.

"I have a good daughter" is not clear about which sense is intended. The various ways to apply prefixes and suffixes can also create ambiguity ("unlockable" can mean "capable of being unlocked" or "impossible to lock"). Semantic and syntactic ambiguity Semantic ambiguity occurs when a word, phrase or sentence, taken out of context, has more than one interpretation. In "We saw her duck" (example due to Richard Nordquist), the words "her duck" can refer either to the person's bird (the noun "duck", modified by the possessive pronoun "her"), or to a motion she made (the verb "duck", the subject of which is the objective pronoun "her", object of the verb "saw").

Metonymy involves referring to one entity by the name of a different but closely related entity (for example, using "wheels" to refer to a car, or "Wall Street" to refer to the stock exchanges located on that street or even the entire US financial sector). In the modern vocabulary of critical semiotics, metonymy encompasses any potentially ambiguous word substitution that is based on contextual contiguity (located close together), or a function or process that an object performs, such as "sweet ride" to refer to a nice car. Metonym miscommunication is considered a primary mechanism of linguistic humor. Philosophy Philosophers (and other users of logic) spend a lot of time and effort searching for and removing (or intentionally adding) ambiguity in arguments because it can lead to incorrect conclusions and can be used to deliberately conceal bad arguments. For example, a politician might say, "I oppose taxes which hinder economic growth", an example of a glittering generality. Some will think they oppose taxes in general because they hinder economic growth. Others may think they oppose only those taxes that they believe will hinder economic growth. In writing, the sentence can be rewritten to reduce possible misinterpretation, either by adding a comma after "taxes" (to convey the first sense) or by changing "which" to "that" (to convey the second sense) or by rewriting it in other ways. The devious politician hopes that each constituent will interpret the statement in the most desirable way, and think the politician supports everyone's opinion. However, the opposite can also be true—an opponent can turn a positive statement into a bad one if the speaker uses ambiguity (intentionally or not). The logical fallacies of amphiboly and equivocation rely heavily on the use of ambiguous words and phrases. In continental philosophy (particularly phenomenology and existentialism), there is much greater tolerance of ambiguity, as it is generally seen as an integral part of the human condition. Martin Heidegger argued that the relation between the subject and object is ambiguous, as is the relation of mind and body, and part and whole. In Heidegger's phenomenology, Dasein is always in a meaningful world, but there is always an underlying background for every instance of signification. Thus, although some things may be certain, they have little to do with Dasein's sense of care and existential anxiety, e.g., in the face of death. In calling his work Being and Nothingness an "essay in phenomenological ontology" Jean-Paul Sartre follows Heidegger in defining the human essence as ambiguous, or relating fundamentally to such ambiguity. Simone de Beauvoir tries to base an ethics on Heidegger's and Sartre's writings (The Ethics of Ambiguity), where she highlights the need to grapple with ambiguity: "as long as there have been philosophers and they have thought, most of them have tried to mask it... And the ethics which they have proposed to their disciples has always pursued the same goal.

It has been a matter of eliminating the ambiguity by making oneself pure inwardness or pure externality, by escaping from the sensible world or being engulfed by it, by yielding to eternity or enclosing oneself in the pure moment." Ethics cannot be based on the authoritative certainty given by mathematics and logic, or prescribed directly from the empirical findings of science. She states: "Since we do not succeed in fleeing it, let us, therefore, try to look the truth in the face. Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting". Other continental philosophers suggest that concepts such as life, nature, and sex are ambiguous. Corey Anton has argued that we cannot be certain what is separate from or unified with something else: language, he asserts, divides what is not, in fact, separate. Following Ernest Becker, he argues that the desire to 'authoritatively disambiguate' the world and existence has led to numerous ideologies and historical events such as genocide. On this basis, he argues that ethics must focus on 'dialectically integrating opposites' and balancing tension, rather than seeking a priori validation or certainty. Like the existentialists and phenomenologists, he sees the ambiguity of life as the basis of creativity. Literature and rhetoric In literature and rhetoric, ambiguity can be a useful tool. Groucho Marx's classic joke depends on a grammatical ambiguity for its humor, for example: "Last night I shot an elephant in my pajamas. How he got in my pajamas, I'll never know". Songs and poetry often rely on ambiguous words for artistic effect, as in the song title "Don't It Make My Brown Eyes Blue" (where "blue" can refer to the color, or to sadness). In the narrative, ambiguity can be introduced in several ways: motive, plot, character. F. Scott Fitzgerald uses the latter type of ambiguity with notable effect in his novel The Great Gatsby. Mathematical notation Mathematical notation, widely used in physics and other sciences, avoids many ambiguities compared to expression in natural language. However, for various reasons, several lexical, syntactic and semantic ambiguities remain. Names of functions The ambiguity in the style of writing a function should not be confused with a multivalued function, which can (and should) be defined in a deterministic and unambiguous way. Several special functions still do not have established notations. Usually, the conversion to another notation requires to scale the argument or the resulting value; sometimes, the same name of the function is used, causing confusions. Examples of such underestablished functions: Sinc function Elliptic integral of the third kind; translating elliptic integral form MAPLE to Mathematica, one should replace the second argument to its square, see Talk:Elliptic integral#List of notations; dealing with complex values, this may cause problems. Exponential integral Hermite polynomial Expressions Ambiguous expressions often appear in physical and mathematical texts. It is common practice to omit multiplication signs in mathematical expressions.

Also, it is common to give the same name to a variable and a function, for example, . Then, if one sees , there is no way to distinguish whether it means multiplied by , or function evaluated at argument equal to . In each case of use of such notations, the reader is supposed to be able to perform the deduction and reveal the true meaning. Creators of algorithmic languages try to avoid ambiguities. Many algorithmic languages (C++ and Fortran) require the character * as symbol of multiplication. The Wolfram Language used in Mathematica allows the user to omit the multiplication symbol, but requires square brackets to indicate the argument of a function; square brackets are not allowed for grouping of expressions. Fortran, in addition, does not allow use of the same name (identifier) for different objects, for example, function and variable; in particular, the expression f=f(x) is qualified as an error. The order of operations may depend on the context. In most programming languages, the operations of division and multiplication have equal priority and are executed from left to right. Until the last century, many editorials assumed that multiplication is performed first, for example, is interpreted as ; in this case, the insertion of parentheses is required when translating the formulas to an algorithmic language. In addition, it is common to write an argument of a function without parenthesis, which also may lead to ambiguity. In the scientific journal style, one uses roman letters to denote elementary functions, whereas variables are written using italics. For example, in mathematical journals the expression does not denote the sine function, but the product of the three variables , , , although in the informal notation of a slide presentation it may stand for . Commas in multi-component subscripts and superscripts are sometimes omitted; this is also potentially ambiguous notation. For example, in the notation , the reader can only infer from the context whether it means a single-index object, taken with the subscript equal to product of variables , and , or it is an indication to a trivalent tensor.

Then, there is an "unwritten rule": the state is coherent if there are more Greek characters than Latin characters in the argument, and photon state if the Latin characters dominate. The ambiguity becomes even worse, if is used for the states with certain value of the coordinate, and means the state with certain value of the momentum, which may be used in books on quantum mechanics. Such ambiguities easily lead to confusions, especially if some normalized adimensional, dimensionless variables are used. Expression may mean a state with single photon, or the coherent state with mean amplitude equal to 1, or state with momentum equal to unity, and so on. The reader is supposed to guess from the context. Ambiguous terms in physics and mathematics Some physical quantities do not yet have established notations; their value (and sometimes even dimension, as in the case of the Einstein coefficients), depends on the system of notations. Many terms are ambiguous. Each use of an ambiguous term should be preceded by the definition, suitable for a specific case. Just like Ludwig Wittgenstein states in Tractatus Logico-Philosophicus: "...Only in the context of a proposition has a name meaning." A highly confusing term is gain. For example, the sentence "the gain of a system should be doubled", without context, means close to nothing. It may mean that the ratio of the output voltage of an electric circuit to the input voltage should be doubled. It may mean that the ratio of the output power of an electric or optical circuit to the input power should be doubled. It may mean that the gain of the laser medium should be doubled, for example, doubling the population of the upper laser level in a quasi-two level system (assuming negligible absorption of the ground-state). The term intensity is ambiguous when applied to light. The term can refer to any of irradiance, luminous intensity, radiant intensity, or radiance, depending on the background of the person using the term. Also, confusions may be related with the use of atomic percent as measure of concentration of a dopant, or resolution of an imaging system, as measure of the size of the smallest detail which still can be resolved at the background of statistical noise. See also Accuracy and precision and its talk. The Berry paradox arises as a result of systematic ambiguity in the meaning of terms such as "definable" or "nameable". Terms of this kind give rise to vicious circle fallacies. Other terms with this type of ambiguity are: satisfiable, true, false, function, property, class, relation, cardinal, and ordinal. Mathematical interpretation of ambiguity In mathematics and logic, ambiguity can be considered to be an instance of the logical concept of underdetermination—for example, leaves open what the value of X is—while its opposite is a self-contradiction, also called inconsistency, paradoxicalness, or oxymoron, or in mathematics an inconsistent system—such as , which has no solution.

Ambiguous terms in physics and mathematics Some physical quantities do not yet have established notations; their value (and sometimes even dimension, as in the case of the Einstein coefficients), depends on the system of notations. Many terms are ambiguous. Each use of an ambiguous term should be preceded by the definition, suitable for a specific case. Just like Ludwig Wittgenstein states in Tractatus Logico-Philosophicus: "...Only in the context of a proposition has a name meaning." A highly confusing term is gain. For example, the sentence "the gain of a system should be doubled", without context, means close to nothing. It may mean that the ratio of the output voltage of an electric circuit to the input voltage should be doubled. It may mean that the ratio of the output power of an electric or optical circuit to the input power should be doubled. It may mean that the gain of the laser medium should be doubled, for example, doubling the population of the upper laser level in a quasi-two level system (assuming negligible absorption of the ground-state). The term intensity is ambiguous when applied to light. The term can refer to any of irradiance, luminous intensity, radiant intensity, or radiance, depending on the background of the person using the term. Also, confusions may be related with the use of atomic percent as measure of concentration of a dopant, or resolution of an imaging system, as measure of the size of the smallest detail which still can be resolved at the background of statistical noise. See also Accuracy and precision and its talk. The Berry paradox arises as a result of systematic ambiguity in the meaning of terms such as "definable" or "nameable". Terms of this kind give rise to vicious circle fallacies. Other terms with this type of ambiguity are: satisfiable, true, false, function, property, class, relation, cardinal, and ordinal. Mathematical interpretation of ambiguity In mathematics and logic, ambiguity can be considered to be an instance of the logical concept of underdetermination—for example, leaves open what the value of X is—while its opposite is a self-contradiction, also called inconsistency, paradoxicalness, or oxymoron, or in mathematics an inconsistent system—such as , which has no solution.

Logical ambiguity and self-contradiction is analogous to visual ambiguity and impossible objects, such as the Necker cube and impossible cube, or many of the drawings of M. C. Escher. Constructed language Some languages have been created with the intention of avoiding ambiguity, especially lexical ambiguity. Lojban and Loglan are two related languages which have been created for this, focusing chiefly on syntactic ambiguity as well. The languages can be both spoken and written. These languages are intended to provide a greater technical precision over big natural languages, although historically, such attempts at language improvement have been criticized. Languages composed from many diverse sources contain much ambiguity and inconsistency. The many exceptions to syntax and semantic rules are time-consuming and difficult to learn. Biology In structural biology, ambiguity has been recognized as a problem for studying protein conformations. The analysis of a protein three-dimensional structure consists in dividing the macromolecule into subunits called domains. The difficulty of this task arises from the fact that different definitions of what a domain is can be used (e.g. folding autonomy, function, thermodynamic stability, or domain motions), which sometimes results in a single protein having different—yet equally valid—domain assignments. Christianity and Judaism Christianity and Judaism employ the concept of paradox synonymously with "ambiguity". Many Christians and Jews endorse Rudolf Otto's description of the sacred as 'mysterium tremendum et fascinans', the awe-inspiring mystery which fascinates humans. The orthodox Catholic writer G. K. Chesterton regularly employed paradox to tease out the meanings in common concepts which he found ambiguous or to reveal meaning often overlooked or forgotten in common phrases. (The title of one of his most famous books, Orthodoxy, itself employing such a paradox.) Music In music, pieces or sections which confound expectations and may be or are interpreted simultaneously in different ways are ambiguous, such as some polytonality, polymeter, other ambiguous meters or rhythms, and ambiguous phrasing, or (Stein 2005, p.79) any aspect of music. The music of Africa is often purposely ambiguous. To quote Sir Donald Francis Tovey (1935, p.195), "Theorists are apt to vex themselves with vain efforts to remove uncertainty just where it has a high aesthetic value." Visual art In visual art, certain images are visually ambiguous, such as the Necker cube, which can be interpreted in two ways. Perceptions of such objects remain stable for a time, then may flip, a phenomenon called multistable perception. The opposite of such ambiguous images are impossible objects. Pictures or photographs may also be ambiguous at the semantic level: the visual image is unambiguous, but the meaning and narrative may be ambiguous: is a certain facial expression one of excitement or fear, for instance? Social psychology and the bystander effect In social psychology, ambiguity is a factor used in determining peoples' responses to various situations. High levels of ambiguity in an emergency (e.g.

Social psychology and the bystander effect In social psychology, ambiguity is a factor used in determining peoples' responses to various situations. High levels of ambiguity in an emergency (e.g.

an unconscious man lying on a park bench) make witnesses less likely to offer any sort of assistance, due to the fear that they may have misinterpreted the situation and acted unnecessarily. Alternately, non-ambiguous emergencies (e.g. an injured person verbally asking for help) illicit more consistent intervention and assistance. With regard to the bystander effect, studies have shown that emergencies deemed ambiguous trigger the appearance of the classic bystander effect (wherein more witnesses decrease the likelihood of any of them helping) far more than non-ambiguous emergencies. Computer science In computer science, the SI prefixes kilo-, mega- and giga- were historically used in certain contexts to mean either the first three powers of 1024 (1024, 10242 and 10243) contrary to the metric system in which these units unambiguously mean one thousand, one million, and one billion. This usage is particularly prevalent with electronic memory devices (e.g. DRAM) addressed directly by a binary machine register where a decimal interpretation makes no practical sense. Subsequently, the Ki, Mi, and Gi prefixes were introduced so that binary prefixes could be written explicitly, also rendering k, M, and G unambiguous in texts conforming to the new standard—this led to a new ambiguity in engineering documents lacking outward trace of the binary prefixes (necessarily indicating the new style) as to whether the usage of k, M, and G remains ambiguous (old style) or not (new style). 1 M (where M is ambiguously 1,000,000 or 1,048,576) is less uncertain than the engineering value 1.0e6 (defined to designate the interval 950,000 to 1,050,000). As non-volatile storage devices begin to exceed 1 GB in capacity (where the ambiguity begins to routinely impact the second significant digit), GB and TB almost always mean 109 and 1012 bytes.

Abel Abel is a Biblical figure in the Book of Genesis within Abrahamic religions. He was the younger brother of Cain, and the younger son of Adam and Eve, the first couple in Biblical history. He was a shepherd who offered his firstborn flock up to God as an offering. God accepted his offering but not his brother's. Cain then killed Abel out of jealousy. According to Genesis, this was the first murder in the history of mankind. Genesis narrative Interpretations Jewish and Christian interpretations According to the narrative in Genesis, Abel ( Hébel, in pausa Hā́ḇel; Hábel; , Hābēl) is Eve's second son. His name in Hebrew is composed of the same three consonants as a root meaning "breath". Julius Wellhausen has proposed that the name is independent of the root. Eberhard Schrader had previously put forward the Akkadian (Old Assyrian dialect) ablu ("son") as a more likely etymology. In Christianity, comparisons are sometimes made between the death of Abel and that of Jesus, the former thus seen as being the first martyr. In Jesus speaks of Abel as "righteous", and the Epistle to the Hebrews states that "The blood of sprinkling ... [speaks] better things than that of Abel" (). The blood of Jesus is interpreted as bringing mercy; but that of Abel as demanding vengeance (hence the curse and mark). Abel is invoked in the litany for the dying in the Roman Catholic Church, and his sacrifice is mentioned in the Canon of the Mass along with those of Abraham and Melchizedek. The Alexandrian Rite commemorates him with a feast day on December 28. According to the Coptic Book of Adam and Eve (at 2:1–15), and the Syriac Cave of Treasures, Abel's body, after many days of mourning, was placed in the Cave of Treasures, before which Adam and Eve, and descendants, offered their prayers. In addition, the Sethite line of the Generations of Adam swear by Abel's blood to segregate themselves from the unrighteous. In the Book of Enoch (22:7), regarded by most Christian and Jewish traditions as extra-biblical, the soul of Abel is described as having been appointed as the chief of martyrs, crying for vengeance, for the destruction of the seed of Cain. This view is later repeated in the Testament of Abraham (A:13 / B:11), where Abel has been raised to the position as the judge of the souls. Sethian Gnostic interpretation In the Apocryphon of John, a work belonging to Sethian Gnosticism, Abel is the offspring of Yaldaboath and Eve, who is placed over the elements of water and earth as Elohim, but was only given his name as a form of deception.

Mandaean interpretation According to Mandaean beliefs and scriptures including the Qolastā, the Book of John and Genzā Rabbā, Abel is cognate with the angelic soteriological figure Hibil Ziwa, (, sometimes translated "Splendid Hibel"), who is spoken of as a son of Hayyi or of Manda d-Hayyi, and as a brother to Anush (Enosh) and to Sheetil (Seth), who is the son of Adam. Elsewhere, Anush is spoken of as the son of Sheetil, and Sheetil as the son of Hibil, where Hibil came to Adam and Eve as a young boy when they were still virgins, but was called their son. Hibil is an important lightworld being (uthra) who conquered the World of Darkness. As Yawar Hibil, he is one of multiple figures known as Yawar (), being so named by and after his father. Islamic interpretation According to Shi'a Muslim belief, Abel ("Habeel") is buried in the Nabi Habeel Mosque, located on the west mountains of Damascus, near the Zabadani Valley, overlooking the villages of the Barada river (Wadi Barada), in Syria. Shi'a are frequent visitors of this mosque for ziyarat. The mosque was built by Ottoman Wali Ahmad Pasha in 1599.

Aardvark The aardvark ( ; Orycteropus afer) is a medium-sized, burrowing, nocturnal mammal native to Africa. It is the only living species of the order Tubulidentata, although other prehistoric species and genera of Tubulidentata are known. Unlike most other insectivores, it has a long pig-like snout, which is used to sniff out food. It roams over most of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeder, it subsists on ants and termites, which it will dig out of their hills using its sharp claws and powerful legs. It also digs to create burrows in which to live and rear its young. The animal is listed as "least concern" by the IUCN, although its numbers are decreasing. Aardvarks are afrotheres, a clade which also includes elephants, manatees, and hyraxes. Name and taxonomy Name The aardvark is sometimes colloquially called the "African ant bear", "anteater" (not to be confused with the South American anteater), or the "Cape anteater" after the Cape of Good Hope. The name "aardvark" is Afrikaans (), comes from earlier Afrikaans erdvark and means "earth pig" or "ground pig" (aarde: "earth/ground", vark: "pig"), because of its burrowing habits. The name Orycteropus means "burrowing foot", and the name afer refers to Africa. The name of the aardvark's order, Tubulidentata, comes from the tubule-style teeth. Taxonomy The aardvark is not closely related to the pig; rather, it is the sole extant representative of the obscure mammalian order Tubulidentata, in which it is usually considered to form one variable species of the genus Orycteropus, the sole surviving genus in the family Orycteropodidae. The aardvark is not closely related to the South American anteater, despite sharing some characteristics and a superficial resemblance. The similarities are based on convergent evolution. The closest living relatives of the aardvark are the elephant shrews, tenrecs and golden moles. Along with the sirenians, hyraxes, elephants, and their extinct relatives, these animals form the superorder Afrotheria. Studies of the brain have shown the similarities with Condylarthra, and given the clade's status as a wastebasket taxon it may mean some species traditionally classified as "condylarths" are actually stem-aardvarks. Evolutionary history Based on fossils, Bryan Patterson has concluded that early relatives of the aardvark appeared in Africa around the end of the Paleocene. The ptolemaiidans, a mysterious clade of mammals with uncertain affinities, may actually be stem-aardvarks, either as a sister clade to Tubulidentata or as a grade leading to true tubulidentates. The first unambiguous tubulidentate was probably Myorycteropus africanus from Kenyan Miocene deposits. The earliest example from the genus Orycteropus was Orycteropus mauritanicus, found in Algeria in deposits from the middle Miocene, with an equally old version found in Kenya. Fossils from the aardvark have been dated to 5 million years, and have been located throughout Europe and the Near East. The mysterious Pleistocene Plesiorycteropus from Madagascar was originally thought to be a tubulidentate that was descended from ancestors that entered the island during the Eocene.

The mysterious Pleistocene Plesiorycteropus from Madagascar was originally thought to be a tubulidentate that was descended from ancestors that entered the island during the Eocene.

However, a number of subtle anatomical differences coupled with recent molecular evidence now lead researchers to believe that Plesiorycteropus is a relative of golden moles and tenrecs that achieved an aardvark-like appearance and ecological niche through convergent evolution. Subspecies The aardvark has seventeen poorly defined subspecies listed: Orycteropus afer afer O. a. adametzi Grote, 1921 O. a. aethiopicus Sundevall, 1843 O. a. angolensis Zukowsky & Haltenorth, 1957 O. a. erikssoni Lönnberg, 1906 O. a. faradjius Hatt, 1932 O. a. haussanus Matschie, 1900 O. a. kordofanicus Rothschild, 1927 O. a. lademanni Grote, 1911 O. a. leptodon Hirst, 1906 O. a. matschiei Grote, 1921 O. a. observandus Grote, 1921 O. a. ruvanensis Grote, 1921 O. a. senegalensis Lesson, 1840 O. a. somalicus Lydekker, 1908 O. a. wardi Lydekker, 1908 O. a. wertheri Matschie, 1898 The 1911 Encyclopædia Britannica also mentions O. a. capensis or Cape ant-bear from South Africa. Description The aardvark is vaguely pig-like in appearance. Its body is stout with a prominently arched back and is sparsely covered with coarse hairs. The limbs are of moderate length, with the rear legs being longer than the forelegs. The front feet have lost the pollex (or 'thumb'), resulting in four toes, while the rear feet have all five toes. Each toe bears a large, robust nail which is somewhat flattened and shovel-like, and appears to be intermediate between a claw and a hoof. Whereas the aardvark is considered digitigrade, it appears at times to be plantigrade. This confusion happens because when it squats it stands on its soles. A contributing characteristic to the burrow digging capabilities of aardvarks is an endosteal tissue called compacted coarse cancellous bone (CCCB). The stress and strain resistance provided by CCCB allows aardvarks to create their burrows, ultimately leading to a favorable environment for plants and a variety of animals. An aardvark's weight is typically between . An aardvark's length is usually between , and can reach lengths of when its tail (which can be up to ) is taken into account. It is tall at the shoulder, and has a girth of about . It is the largest member of the proposed clade Afroinsectiphilia. The aardvark is pale yellowish-gray in color and often stained reddish-brown by soil. The aardvark's coat is thin, and the animal's primary protection is its tough skin. Its hair is short on its head and tail; however its legs tend to have longer hair. The hair on the majority of its body is grouped in clusters of 3-4 hairs. The hair surrounding its nostrils is dense to help filter particulate matter out as it digs. Its tail is very thick at the base and gradually tapers. Head The greatly elongated head is set on a short, thick neck, and the end of the snout bears a disc, which houses the nostrils. It contains a thin but complete zygomatic arch. The head of the aardvark contains many unique and different features.

The head of the aardvark contains many unique and different features.

One of the most distinctive characteristics of the Tubulidentata is their teeth, Instead of having a pulp cavity, each tooth has a cluster of thin, hexagonal, upright, parallel tubes of vasodentin (a modified form of dentine), with individual pulp canals, held together by cementum. The number of columns is dependent on the size of the tooth, with the largest having about 1,500. The teeth have no enamel coating and are worn away and regrow continuously. The aardvark is born with conventional incisors and canines at the front of the jaw, which fall out and are not replaced. Adult aardvarks have only cheek teeth at the back of the jaw, and have a dental formula of: These remaining teeth are peg-like and rootless and are of unique composition. The teeth consist of 14 upper and 12 lower jaw molars. The nasal area of the aardvark is another unique area, as it contains ten nasal conchae, more than any other placental mammal. The sides of the nostrils are thick with hair. The tip of the snout is highly mobile and is moved by modified mimetic muscles. The fleshy dividing tissue between its nostrils probably has sensory functions, but it is uncertain whether they are olfactory or vibratory in nature. Its nose is made up of more turbinate bones than any other mammal, with between 9 and 11, compared to dogs with 4 to 5. With a large quantity of turbinate bones, the aardvark has more space for the moist epithelium, which is the location of the olfactory bulb. The nose contains nine olfactory bulbs, more than any other mammal. Its keen sense of smell is not just from the quantity of bulbs in the nose but also in the development of the brain, as its olfactory lobe is very developed. The snout resembles an elongated pig snout. The mouth is small and tubular, typical of species that feed on ants and termites. The aardvark has a long, thin, snakelike, protruding tongue (as much as long) and elaborate structures supporting a keen sense of smell. The ears, which are very effective, are disproportionately long, about long. The eyes are small for its head, and consist only of rods. Digestive system The aardvark's stomach has a muscular pyloric area that acts as a gizzard to grind swallowed food up, thereby rendering chewing unnecessary. Its cecum is large. Both sexes emit a strong smelling secretion from an anal gland. Its salivary glands are highly developed and almost completely ring the neck; their output is what causes the tongue to maintain its tackiness. The female has two pairs of teats in the inguinal region. Genetically speaking, the aardvark is a living fossil, as its chromosomes are highly conserved, reflecting much of the early eutherian arrangement before the divergence of the major modern taxa. Habitat and range Aardvarks are found in sub-Saharan Africa, where suitable habitat (savannas, grasslands, woodlands and bushland) and food (i.e., ants and termites) is available.

One of the most distinctive characteristics of the Tubulidentata is their teeth, Instead of having a pulp cavity, each tooth has a cluster of thin, hexagonal, upright, parallel tubes of vasodentin (a modified form of dentine), with individual pulp canals, held together by cementum. The number of columns is dependent on the size of the tooth, with the largest having about 1,500. The teeth have no enamel coating and are worn away and regrow continuously. The aardvark is born with conventional incisors and canines at the front of the jaw, which fall out and are not replaced. Adult aardvarks have only cheek teeth at the back of the jaw, and have a dental formula of: These remaining teeth are peg-like and rootless and are of unique composition. The teeth consist of 14 upper and 12 lower jaw molars. The nasal area of the aardvark is another unique area, as it contains ten nasal conchae, more than any other placental mammal. The sides of the nostrils are thick with hair. The tip of the snout is highly mobile and is moved by modified mimetic muscles. The fleshy dividing tissue between its nostrils probably has sensory functions, but it is uncertain whether they are olfactory or vibratory in nature. Its nose is made up of more turbinate bones than any other mammal, with between 9 and 11, compared to dogs with 4 to 5. With a large quantity of turbinate bones, the aardvark has more space for the moist epithelium, which is the location of the olfactory bulb. The nose contains nine olfactory bulbs, more than any other mammal. Its keen sense of smell is not just from the quantity of bulbs in the nose but also in the development of the brain, as its olfactory lobe is very developed. The snout resembles an elongated pig snout. The mouth is small and tubular, typical of species that feed on ants and termites. The aardvark has a long, thin, snakelike, protruding tongue (as much as long) and elaborate structures supporting a keen sense of smell. The ears, which are very effective, are disproportionately long, about long. The eyes are small for its head, and consist only of rods. Digestive system The aardvark's stomach has a muscular pyloric area that acts as a gizzard to grind swallowed food up, thereby rendering chewing unnecessary. Its cecum is large. Both sexes emit a strong smelling secretion from an anal gland.

Habitat and range Aardvarks are found in sub-Saharan Africa, where suitable habitat (savannas, grasslands, woodlands and bushland) and food (i.e., ants and termites) is available.

They spend the daylight hours in dark burrows to avoid the heat of the day. The only major habitat that they are not present in is swamp forest, as the high water table precludes digging to a sufficient depth. They also avoid terrain rocky enough to cause problems with digging. They have been documented as high as in Ethiopia. They are present throughout sub-Saharan Africa all the way to South Africa with few exceptions including the coastal areas of Namibia, Ivory Coast, and Ghana. They are not found in Madagascar. Ecology and behaviour Aardvarks live for up to 23 years in captivity. Its keen hearing warns it of predators: lions, leopards, cheetahs, African wild dogs, hyenas, and pythons. Some humans also hunt aardvarks for meat. Aardvarks can dig fast or run in zigzag fashion to elude enemies, but if all else fails, they will strike with their claws, tail and shoulders, sometimes flipping onto their backs lying motionless except to lash out with all four feet. They are capable of causing substantial damage to unprotected areas of an attacker. They will also dig to escape as they can. Sometimes, when pressed, aardvarks can dig extremely quickly . Feeding The aardvark is nocturnal and is a solitary creature that feeds almost exclusively on ants and termites (myrmecophagy); the only fruit eaten by aardvarks is the aardvark cucumber. In fact, the cucumber and the aardvark have a symbiotic relationship as they eat the subterranean fruit, then defecate the seeds near their burrows, which then grow rapidly due to the loose soil and fertile nature of the area. The time spent in the intestine of the aardvark helps the fertility of the seed, and the fruit provides needed moisture for the aardvark. They avoid eating the African driver ant and red ants. Due to their stringent diet requirements, they require a large range to survive. An aardvark emerges from its burrow in the late afternoon or shortly after sunset, and forages over a considerable home range encompassing . While foraging for food, the aardvark will keep its nose to the ground and its ears pointed forward, which indicates that both smell and hearing are involved in the search for food. They zig-zag as they forage and will usually not repeat a route for 5–8 days as they appear to allow time for the termite nests to recover before feeding on it again. During a foraging period, they will stop to dig a "V" shaped trench with their forefeet and then sniff it profusely as a means to explore their location. When a concentration of ants or termites is detected, the aardvark digs into it with its powerful front legs, keeping its long ears upright to listen for predators, and takes up an astonishing number of insects with its long, sticky tongue—as many as 50,000 in one night have been recorded. Its claws enable it to dig through the extremely hard crust of a termite or ant mound quickly.

Its claws enable it to dig through the extremely hard crust of a termite or ant mound quickly.

It avoids inhaling the dust by sealing the nostrils. When successful, the aardvark's long (up to ) tongue licks up the insects; the termites' biting, or the ants' stinging attacks are rendered futile by the tough skin. After an aardvark visit at a termite mound, other animals will visit to pick up all the leftovers. Termite mounds alone don't provide enough food for the aardvark, so they look for termites that are on the move. When these insects move, they can form columns long and these tend to provide easy pickings with little effort exerted by the aardvark. These columns are more common in areas of livestock or other hoofed animals. The trampled grass and dung attract termites from the Odontotermes, Microtermes, and Pseudacanthotermes genera. On a nightly basis they tend to be more active during the first portion of night (roughly the four hours between 8:00p.m. and 12:00a.m. ); however, they don't seem to prefer bright or dark nights over the other. During adverse weather or if disturbed they will retreat to their burrow systems. They cover between per night; however, some studies have shown that they may traverse as far as in a night. Vocalization The aardvark is a rather quiet animal. However, it does make soft grunting sounds as it forages and loud grunts as it makes for its tunnel entrance. It makes a bleating sound if frightened. When it is threatened it will make for one of its burrows. If one is not close it will dig a new one rapidly. This new one will be short and require the aardvark to back out when the coast is clear. Movement The aardvark is known to be a good swimmer and has been witnessed successfully swimming in strong currents. It can dig a yard of tunnel in about five minutes, but otherwise moves fairly slowly. When leaving the burrow at night, they pause at the entrance for about ten minutes, sniffing and listening. After this period of watchfulness, it will bound out and within seconds it will be away. It will then pause, prick its ears, twisting its head to listen, then jump and move off to start foraging. Aside from digging out ants and termites, the aardvark also excavates burrows in which to live, which generally fall into one of three categories: burrows made while foraging, refuge and resting location, and permanent homes. Temporary sites are scattered around the home range and are used as refuges, while the main burrow is also used for breeding. Main burrows can be deep and extensive, have several entrances and can be as long as . These burrows can be large enough for a person to enter. The aardvark changes the layout of its home burrow regularly, and periodically moves on and makes a new one. The old burrows are an important part of the African wildlife scene. As they are vacated, then they are inhabited by smaller animals like the African wild dog, ant-eating chat, Nycteris thebaica and warthogs.

Other animals that use them are hares, mongooses, hyenas, owls, pythons, and lizards. Without these refuges many animals would die during wildfire season. Only mothers and young share burrows; however, the aardvark is known to live in small family groups or as a solitary creature. If attacked in the tunnel, it will escape by digging out of the tunnel thereby placing the fresh fill between it and its predator, or if it decides to fight it will roll onto its back, and attack with its claws. The aardvark has been known to sleep in a recently excavated ant nest, which also serves as protection from its predators. Reproduction Aardvarks pair only during the breeding season; after a gestation period of seven months, one cub weighing around is born during May–July. When born, the young has flaccid ears and many wrinkles. When nursing, it will nurse off each teat in succession. After two weeks, the folds of skin disappear and after three, the ears can be held upright. After 5–6 weeks, body hair starts growing. It is able to leave the burrow to accompany its mother after only two weeks and eats termites at 9 weeks, and is weaned between three months and 16 weeks. At six months of age, it is able to dig its own burrows, but it will often remain with the mother until the next mating season, and is sexually mature from approximately two years of age. Conservation Aardvarks were thought to have declining numbers, however, this is possibly because they are not readily seen. There are no definitive counts because of their nocturnal and secretive habits; however, their numbers seem to be stable overall. They are not considered common anywhere in Africa, but due to their large range, they maintain sufficient numbers. There may be a slight decrease in numbers in eastern, northern, and western Africa. Southern African numbers are not decreasing. It receives an official designation from the IUCN as least concern. However, they are a species in a precarious situation, as they are so dependent on such specific food; therefore if a problem arises with the abundance of termites, the species as a whole would be affected drastically. Aardvarks handle captivity well. The first zoo to have one was London Zoo in 1869, which had an animal from South Africa. Mythology and popular culture In African folklore, the aardvark is much admired because of its diligent quest for food and its fearless response to soldier ants. Hausa magicians make a charm from the heart, skin, forehead, and nails of the aardvark, which they then proceed to pound together with the root of a certain tree. Wrapped in a piece of skin and worn on the chest, the charm is said to give the owner the ability to pass through walls or roofs at night. The charm is said to be used by burglars and those seeking to visit young girls without their parents' permission.

Also, some tribes, such as the Margbetu, Ayanda, and Logo, will use aardvark teeth to make bracelets, which are regarded as good luck charms. The meat, which has a resemblance to pork, is eaten in certain cultures. The ancient Egyptian god Set is usually depicted with the head of an unidentified animal, whose similarity to an aardvark has been noted in scholarship. The titular character of Arthur, an animated television series for children based on a book series and produced by WGBH, shown in more than 180 countries, is an aardvark. In the first book of the series, Arthur's Nose (1976), he has a long, aardvark-like nose, but in later books, his face becomes more rounded. Otis the Aardvark was a puppet character used on Children's BBC programming. An aardvark features as the antagonist in the cartoon The Ant and the Aardvark as well as in the Canadian animated series The Raccoons. The supersonic fighter-bomber F-111/FB-111 was nicknamed the Aardvark because of its long nose resembling the animal. It also had similarities with its nocturnal missions flown at a very low level employing ordnance that could penetrate deep into the ground. In the US Navy, the squadron VF-114 was nicknamed the Aardvarks, flying F-4s and then F-14s. The squadron mascot was adapted from the animal in the comic strip B.C., which the F-4 was said to resemble. Cerebus the Aardvark is a 300-issue comic book series by Dave Sim.

Also, some tribes, such as the Margbetu, Ayanda, and Logo, will use aardvark teeth to make bracelets, which are regarded as good luck charms. The meat, which has a resemblance to pork, is eaten in certain cultures. The ancient Egyptian god Set is usually depicted with the head of an unidentified animal, whose similarity to an aardvark has been noted in scholarship. The titular character of Arthur, an animated television series for children based on a book series and produced by WGBH, shown in more than 180 countries, is an aardvark. In the first book of the series, Arthur's Nose (1976), he has a long, aardvark-like nose, but in later books, his face becomes more rounded. Otis the Aardvark was a puppet character used on Children's BBC programming. An aardvark features as the antagonist in the cartoon The Ant and the Aardvark as well as in the Canadian animated series The Raccoons. The supersonic fighter-bomber F-111/FB-111 was nicknamed the Aardvark because of its long nose resembling the animal. It also had similarities with its nocturnal missions flown at a very low level employing ordnance that could penetrate deep into the ground. In the US Navy, the squadron VF-114 was nicknamed the Aardvarks, flying F-4s and then F-14s.

Aardwolf The aardwolf (Proteles cristata) is an insectivorous mammal in the family Hyaenidae, native to East and Southern Africa. Its name means "earth-wolf" in Afrikaans and Dutch. It is also called "maanhaar-jackal" (Afrikaans for "mane-jackal"), "termite-eating hyena" and "civet hyena", based on its habit of secreting substances from its anal gland, a characteristic shared with the African civet. Unlike many of its relatives in the order Carnivora, the aardwolf does not hunt large animals. It eats insects and their larvae, mainly termites; one aardwolf can lap up as many as 250,000 termites during a single night using its long, sticky tongue. The aardwolf's tongue has adapted to be tough enough to withstand the strong bite of termites. The aardwolf lives in the shrublands of eastern and southern Africa – open lands covered with stunted trees and shrubs. It is nocturnal, resting in burrows during the day and emerging at night to seek food. Taxonomy The aardwolf is generally classified with the hyena family Hyaenidae, though it was formerly placed in its own family Protelidae. Early on, scientists felt that it was merely mimicking the striped hyena, which subsequently led to the creation of Protelidae. Recent studies have suggested that the aardwolf probably diverged from other hyaenids early on; how early is still unclear, as the fossil record and genetic studies disagree by 10 million years. The aardwolf is the only surviving species in the subfamily Protelinae. There is disagreement as to whether the species is monotypic, or can be divided into subspecies P. c. cristatus of Southern Africa and P. c. septentrionalis of East Africa. Etymology The generic name proteles comes from two words both of Greek origin, protos and teleos which combined means "complete in front" based on the fact that they have five toes on their front feet and four on the rear. The specific name, cristatus, comes from Latin and means "provided with a comb", relating to their mane. Description The aardwolf resembles a very thin striped hyena, but with a more slender muzzle, black vertical stripes on a coat of yellowish fur, and a long, distinct mane down the midline of the neck and back. It also has one or two diagonal stripes down the fore- and hind-quarters, along with several stripes on its legs. The mane is raised during confrontations to make the aardwolf appear larger. It is missing the throat spot that others in the family have. Its lower leg (from the knee down) is all black, and its tail is bushy with a black tip. The aardwolf is about long, excluding its bushy tail, which is about long, and stands about tall at the shoulders. An adult aardwolf weighs approximately , sometimes reaching . The aardwolves in the south of the continent tend to be smaller (about )than the eastern version (around ). This makes the aardwolf, the smallest extant member of the Hyaenidae family. The front feet have five toes each, unlike the four-toed hyena.

The front feet have five toes each, unlike the four-toed hyena.

The teeth and skull are similar to those of other hyenas, though smaller, and its cheek teeth are specialised for eating insects. It does still have canines, but, unlike other hyenas, these teeth are used primarily for fighting and defense. Its ears, which are large, are very similar to those of the striped hyena. As an aardwolf ages, it will normally lose some of its teeth, though this has little impact on its feeding habits due to the softness of the insects that it eats. Distribution and habitat Aardwolves live in open, dry plains and bushland, avoiding mountainous areas. Due to their specific food requirements, they are only found in regions where termites of the family Hodotermitidae occur. Termites of this family depend on dead and withered grass and are most populous in heavily grazed grasslands and savannahs, including farmland. For most of the year, aardwolves spend time in shared territories consisting of up to a dozen dens, which are occupied for six weeks at a time. There are two distinct populations: one in Southern Africa, and another in East and Northeast Africa. The species does not occur in the intermediary miombo forests. An adult pair, along with their most-recent offspring, occupies a territory of . Behavior Aardwolves are shy and nocturnal, sleeping in burrows by day. They will, on occasion during the winter, become diurnal feeders. This happens during the coldest periods as they then stay in at night to conserve heat. They have often been mistaken for solitary animals. In fact, they live as monogamous pairs with their young. If their territory is infringed upon, they will chase the intruder up to or to the border. If the intruder is caught, which rarely happens, a fight will occur, which is accompanied by soft clucking, hoarse barking, and a type of roar. The majority of incursions occur during mating season, when they can occur once or twice per week. When food is scarce, the stringent territorial system may be abandoned and as many as three pairs may occupy a single territory. The territory is marked by both sexes, as they both have developed anal glands from which they extrude a black substance that is smeared on rocks or grass stalks in -long streaks. Aardwolves also have scent glands on the forefoot and penile pad. They often mark near termite mounds within their territory every 20 minutes or so. If they are patrolling their territorial boundaries, the marking frequency increases drastically, to once every . At this rate, an individual may mark 60 marks per hour, and upwards of 200 per night. An aardwolf pair may have up to 10 dens, and numerous feces middens, within their territory. When they deposit excreta at their middens, they dig a small hole and cover it with sand. Their dens are usually abandoned aardvark, springhare, or porcupine dens, or on occasion they are crevices in rocks. They will also dig their own dens, or enlarge dens started by springhares.

They typically will only use one or two dens at a time, rotating through all of their dens every six months. During the summer, they may rest outside their den during the night, and sleep underground during the heat of the day. Aardwolves are not fast runners nor are they particularly adept at fighting off predators. Therefore, when threatened, the aardwolf may attempt to mislead its foe by doubling back on its tracks. If confronted, it may raise its mane in an attempt to appear more menacing. It also emits a foul-smelling liquid from its anal glands. Feeding The aardwolf feeds primarily on termites and more specifically on Trinervitermes. This genus of termites has different species throughout the aardwolf's range. In East Africa, they eat Trinervitermes bettonianus, in central Africa, they eat Trinervitermes rhodesiensis, and in southern Africa, they eat T. trinervoides. Their technique consists of licking them off the ground as opposed to the aardvark, which digs into the mound. They locate their food by sound and also from the scent secreted by the soldier termites. An aardwolf may consume up to 250,000 termites per night using its long, sticky tongue. They do not destroy the termite mound or consume the entire colony, thus ensuring that the termites can rebuild and provide a continuous supply of food. They often memorize the location of such nests and return to them every few months. During certain seasonal events, such as the onset of the rainy season and the cold of midwinter, the primary termites become scarce, so the need for other foods becomes pronounced. During these times, the southern aardwolf will seek out Hodotermes mossambicus, a type of harvester termite active in the afternoon, which explains some of their diurnal behavior in the winter. The eastern aardwolf, during the rainy season, subsists on termites from the genera Odontotermes and Macrotermes. They are also known to feed on other insects, larvae, eggs, and, some sources say, occasionally small mammals and birds, but these constitute a very small percentage of their total diet. Unlike other hyenas, aardwolves do not scavenge or kill larger animals. Contrary to popular myths, aardwolves do not eat carrion, and if they are seen eating while hunched over a dead carcass, they are actually eating larvae and beetles. Also, contrary to some sources, they do not like meat, unless it is finely ground or cooked for them. The adult aardwolf was formerly assumed to forage in small groups, but more recent research has shown that they are primarily solitary foragers, necessary because of the scarcity of their insect prey. Their primary source, Trinervitermes, forages in small but dense patches of . While foraging, the aardwolf can cover about per hour, which translates to per summer night and per winter night. Breeding The breeding season varies depending on location, but normally takes place during autumn or spring. In South Africa, breeding occurs in early July.

During the breeding season, unpaired male aardwolves search their own territory, as well as others, for a female to mate with. Dominant males also mate opportunistically with the females of less dominant neighboring aardwolves, which can result in conflict between rival males. Dominant males even go a step further and as the breeding season approaches, they make increasingly greater and greater incursions onto weaker males' territories. As the female comes into oestrus, they add pasting to their tricks inside of the other territories, sometimes doing so more in rivals' territories than their own. Females will also, when given the opportunity, mate with the dominant male, which increases the chances of the dominant male guarding "his" cubs with her. Copulation lasts between 1 and 4.5 hours. Gestation lasts between 89 and 92 days, producing two to five cubs (most often two or three) during the rainy season (November–December), when termites are more active. They are born with their eyes open, but initially are helpless, and weigh around . The first six to eight weeks are spent in the den with their parents. The male may spend up to six hours a night watching over the cubs while the mother is out looking for food. After three months, they begin supervised foraging, and by four months are normally independent, though they often share a den with their mother until the next breeding season. By the time the next set of cubs is born, the older cubs have moved on. Aardwolves generally achieve sexual maturity at one and a half to two years of age. Conservation The aardwolf has not seen decreasing numbers and is relatively widespread throughout eastern Africa. They are not common throughout their range, as they maintain a density of no more than 1 per square kilometer, if food is abundant. Because of these factors, the IUCN has rated the aardwolf as least concern. In some areas, they are persecuted because of the mistaken belief that they prey on livestock; however, they are actually beneficial to the farmers because they eat termites that are detrimental. In other areas, the farmers have recognized this, but they are still killed, on occasion, for their fur. Dogs and insecticides are also common killers of the aardwolf. Interaction with humans Aardwolves are rare sights at zoos. Frankfurt Zoo in Germany was home to the oldest recorded aardwolf in captivity at 18 years and 11 months.

Adobe Adobe (; ) is a building material made from earth and organic materials, is Spanish for mudbrick. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. Adobe architecture has been dated to before 5,100 B.C. Description Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured weighing about ; in other contexts the size is weighing about . The maximum sizes can reach up to ; above this weight it becomes difficult to move the pieces, and it is preferred to ram the mud in situ, resulting in a different typology known as rammed earth. Strength In dry climates, adobe structures are extremely durable, and account for some of the oldest existing buildings in the world. Adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to earthquake damage if they are not reinforced. Cases where adobe structures were widely damaged during earthquakes include the 1976 Guatemala earthquake, the 2003 Bam earthquake, and the 2010 Chile earthquake. Distribution Buildings made of sun-dried earth are common throughout the world (Middle East, Western Asia, North Africa, West Africa, South America, southwestern North America, Spain, and Eastern Europe.) Adobe had been in use by indigenous peoples of the Americas in the Southwestern United States, Mesoamerica, and the Andes for several thousand years. Puebloan peoples built their adobe structures with handsful or basketsful of adobe, until the Spanish introduced them to making bricks.

Adobe Adobe (; ) is a building material made from earth and organic materials, is Spanish for mudbrick. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. Adobe architecture has been dated to before 5,100 B.C. Description Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured weighing about ; in other contexts the size is weighing about . The maximum sizes can reach up to ; above this weight it becomes difficult to move the pieces, and it is preferred to ram the mud in situ, resulting in a different typology known as rammed earth. Strength In dry climates, adobe structures are extremely durable, and account for some of the oldest existing buildings in the world. Adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to earthquake damage if they are not reinforced. Cases where adobe structures were widely damaged during earthquakes include the 1976 Guatemala earthquake, the 2003 Bam earthquake, and the 2010 Chile earthquake. Distribution Buildings made of sun-dried earth are common throughout the world (Middle East, Western Asia, North Africa, West Africa, South America, southwestern North America, Spain, and Eastern Europe.) Adobe had been in use by indigenous peoples of the Americas in the Southwestern United States, Mesoamerica, and the Andes for several thousand years. Puebloan peoples built their adobe structures with handsful or basketsful of adobe, until the Spanish introduced them to making bricks. Adobe bricks were used in Spain from the Late Bronze and Iron Ages (eighth century BCE onwards). Its wide use can be attributed to its simplicity of design and manufacture, and economics.

In more modern English usage, the term "adobe" has come to include a style of architecture popular in the desert climates of North America, especially in New Mexico, regardless of the construction method. Composition An adobe brick is a composite material made of earth mixed with water and an organic material such as straw or dung. The soil composition typically contains sand, silt and clay. Straw is useful in binding the brick together and allowing the brick to dry evenly, thereby preventing cracking due to uneven shrinkage rates through the brick. Dung offers the same advantage. The most desirable soil texture for producing the mud of adobe is 15% clay, 10–30% silt, and 55–75% fine sand. Another source quotes 15–25% clay and the remainder sand and coarser particles up to cobbles , with no deleterious effect. Modern adobe is stabilized with either emulsified asphalt or Portland cement up to 10% by weight. No more than half the clay content should be expansive clays, with the remainder non-expansive illite or kaolinite. Too much expansive clay results in uneven drying through the brick, resulting in cracking, while too much kaolinite will make a weak brick. Typically the soils of the Southwest United States, where such construction has been widely used, are an adequate composition. Material properties Adobe walls are load bearing, i.e. they carry their own weight into the foundation rather than by another structure, hence the adobe must have sufficient compressive strength. In the United States, most building codes call for a minimum compressive strength of 300 lbf/in2 (2.07 newton/mm2) for the adobe block. Adobe construction should be designed so as to avoid lateral structural loads that would cause bending loads. The building codes require the building sustain a 1 g lateral acceleration earthquake load. Such an acceleration will cause lateral loads on the walls, resulting in shear and bending and inducing tensile stresses. To withstand such loads, the codes typically call for a tensile modulus of rupture strength of at least 50 lbf/in2 (0.345 newton/mm2) for the finished block. In addition to being an inexpensive material with a small resource cost, adobe can serve as a significant heat reservoir due to the thermal properties inherent in the massive walls typical in adobe construction. In climates typified by hot days and cool nights, the high thermal mass of adobe mediates the high and low temperatures of the day, moderating the temperature of the living space. The massive walls require a large and relatively long input of heat from the sun (radiation) and from the surrounding air (convection) before they warm through to the interior. After the sun sets and the temperature drops, the warm wall will continue to transfer heat to the interior for several hours due to the time-lag effect. Thus, a well-planned adobe wall of the appropriate thickness is very effective at controlling inside temperature through the wide daily fluctuations typical of desert climates, a factor which has contributed to its longevity as a building material.

Thermodynamic material properties have significant variation in the literature. Some experiments suggest that the standard consideration of conductivity is not adequate for this material, as its main thermodynamic property is inertia, and conclude that experimental tests should be performed over a longer period of time than usual - preferably with changing thermal jumps. There is an effective R-value for a north facing 10-in wall of R0=10 hr ft2 °F/Btu, which corresponds to thermal conductivity k=10 in x 1 ft/12 in /R0=0.33 Btu/(hr ft °F) or 0.57 W/(m K) in agreement with the thermal conductivity reported from another source. To determine the total R-value of a wall, scale R0 by the thickness of the wall in inches. The thermal resistance of adobe is also stated as an R-value for a 10-inch wall R0=4.1 hr ft2 °F/Btu. Another source provides the following properties: conductivity=0.30 Btu/(hr ft °F) or 0.52 W/(m K); specific heat capacity=0.24 Btu/(lb °F) or 1 kJ/(kg K) and density=106 lb/ft3 or 1700 kg/m3, giving heat capacity=25.4 Btu/(ft3 °F) or 1700 kJ/(m3 K). Using the average value of the thermal conductivity as k = 32 Btu/(hr ft °F) or 0.55 W/(m K), the thermal diffusivity is calculated to be 0.013 ft2/h or 3.3x10−7 m2/s. Uses Poured and puddled adobe walls Poured and puddled adobe (puddled clay, piled earth), today called cob, is made by placing soft adobe in layers, rather than by making individual dried bricks or using a form. "Puddle" is a general term for a clay or clay and sand-based material worked into a dense, plastic state. These are the oldest methods of building with adobe in the Americas until holes in the ground were used as forms, and later wooden forms used to make individual bricks were introduced by the Spanish. Adobe bricks Bricks made from adobe are usually made by pressing the mud mixture into an open timber frame. In North America, the brick is typically about in size. The mixture is molded into the frame, which is removed after initial setting. After drying for a few hours, the bricks are turned on edge to finish drying. Slow drying in shade reduces cracking. The same mixture, without straw, is used to make mortar and often plaster on interior and exterior walls. Some cultures used lime-based cement for the plaster to protect against rain damage. Depending on the form into which the mixture is pressed, adobe can encompass nearly any shape or size, provided drying is even and the mixture includes reinforcement for larger bricks. Reinforcement can include manure, straw, cement, rebar, or wooden posts. Straw, cement, or manure added to a standard adobe mixture can produce a stronger, more crack-resistant brick. A test is done on the soil content first. To do so, a sample of the soil is mixed into a clear container with some water, creating an almost completely saturated liquid. The container is shaken vigorously for one minute.

It is then allowed to settle for a day until the soil has settled into layers. Heavier particles settle out first, sand above, silt above that, and very fine clay and organic matter will stay in suspension for days. After the water has cleared, percentages of the various particles can be determined. Fifty to 60 percent sand and 35 to 40 percent clay will yield strong bricks. The Cooperative State Research, Education, and Extension Service at New Mexico State University recommends a mix of not more than ⅓ clay, not less than ½ sand, and never more than ⅓ silt. During the Great Depression, designer and builder Hugh W. Comstock used cheaper materials and made a specialized adobe brick called "Bitudobe." His first adobe house was built in 1936. In 1948, he published the book Post-Adobe; Simplified Adobe Construction Combining A Rugged Timber Frame And Modern Stabilized Adobe, which described his method of construction, including how to make "Bitudobe." In 1938, he served as an adviser to the architects Franklin & Kump Associates, who built the Carmel High School, which used his Post-adobe system. Adobe wall construction The ground supporting an adobe structure should be compressed, as the weight of adobe wall is significant and foundation settling may cause cracking of the wall. Footing depth is to be below the ground frost level. The footing and stem wall are commonly 24 and 14 inches thick, respectively. Modern construction codes call for the use of reinforcing steel in the footing and stem wall. Adobe bricks are laid by course. Adobe walls usually never rise above two stories as they are load bearing and adobe has low structural strength. When creating window and door openings, a lintel is placed on top of the opening to support the bricks above. Atop the last courses of brick, bond beams made of heavy wood beams or modern reinforced concrete are laid to provide a horizontal bearing plate for the roof beams and to redistribute lateral earthquake loads to shear walls more able to carry the forces. To protect the interior and exterior adobe walls, finishes such as mud plaster, whitewash or stucco can be applied. These protect the adobe wall from water damage, but need to be reapplied periodically. Alternatively, the walls can be finished with other nontraditional plasters that provide longer protection. Bricks made with stabilized adobe generally do not need protection of plasters. Adobe roof The traditional adobe roof has been constructed using a mixture of soil/clay, water, sand and organic materials. The mixture was then formed and pressed into wood forms, producing rows of dried earth bricks that would then be laid across a support structure of wood and plastered into place with more adobe. Depending on the materials available, a roof may be assembled using wood or metal beams to create a framework to begin layering adobe bricks.

Depending on the materials available, a roof may be assembled using wood or metal beams to create a framework to begin layering adobe bricks.

Depending on the thickness of the adobe bricks, the framework has been preformed using a steel framing and a layering of a metal fencing or wiring over the framework to allow an even load as masses of adobe are spread across the metal fencing like cob and allowed to air dry accordingly. This method was demonstrated with an adobe blend heavily impregnated with cement to allow even drying and prevent cracking. The more traditional flat adobe roofs are functional only in dry climates that are not exposed to snow loads. The heaviest wooden beams, called vigas, lie atop the wall. Across the vigas lie smaller members called latillas and upon those brush is then laid. Finally, the adobe layer is applied. To construct a flat adobe roof, beams of wood were laid to span the building, the ends of which were attached to the tops of the walls. Once the vigas, latillas and brush are laid, adobe bricks are placed. An adobe roof is often laid with bricks slightly larger in width to ensure a greater expanse is covered when placing the bricks onto the roof. Following each individual brick should be a layer of adobe mortar, recommended to be at least thick to make certain there is ample strength between the brick's edges and also to provide a relative moisture barrier during rain. Roof design evolved around 1850 in the American Southwest. Three inches of adobe mud was applied on top of the latillas, then 18 inches of dry adobe dirt applied to the roof. The dirt was contoured into a low slope to a downspout aka a 'canal'. When moisture was applied to the roof the clay particles expanded to create a waterproof membrane. Once a year it was necessary to pull the weeds from the roof and re-slope the dirt as needed. Depending on the materials, adobe roofs can be inherently fire-proof. The construction of a chimney can greatly influence the construction of the roof supports, creating an extra need for care in choosing the materials. The builders can make an adobe chimney by stacking simple adobe bricks in a similar fashion as the surrounding walls. In 1927, the Uniform Building Code (UBC) was adopted in the United States. Local ordinances, referencing the UBC added requirements to building with adobe. These included: restriction of building height of adobe structures to 1-story, requirements for adobe mix (compressive and shear strength) and new requirements which stated that every building shall be designed to withstand seismic activity, specifically lateral forces. By the 1980s however, seismic related changes in the California Building Code effectively ended solid wall adobe construction in California; however Post-and-Beam adobe and veneers are still being used. Adobe around the world The largest structure ever made from adobe is the Arg-é Bam built by the Achaemenid Empire. Other large adobe structures are the Huaca del Sol in Peru, with 100 million signed bricks and the ciudellas of Chan Chan and Tambo Colorado, both in Peru.

Other large adobe structures are the Huaca del Sol in Peru, with 100 million signed bricks and the ciudellas of Chan Chan and Tambo Colorado, both in Peru.

Depending on the thickness of the adobe bricks, the framework has been preformed using a steel framing and a layering of a metal fencing or wiring over the framework to allow an even load as masses of adobe are spread across the metal fencing like cob and allowed to air dry accordingly. This method was demonstrated with an adobe blend heavily impregnated with cement to allow even drying and prevent cracking. The more traditional flat adobe roofs are functional only in dry climates that are not exposed to snow loads. The heaviest wooden beams, called vigas, lie atop the wall. Across the vigas lie smaller members called latillas and upon those brush is then laid. Finally, the adobe layer is applied. To construct a flat adobe roof, beams of wood were laid to span the building, the ends of which were attached to the tops of the walls. Once the vigas, latillas and brush are laid, adobe bricks are placed. An adobe roof is often laid with bricks slightly larger in width to ensure a greater expanse is covered when placing the bricks onto the roof. Following each individual brick should be a layer of adobe mortar, recommended to be at least thick to make certain there is ample strength between the brick's edges and also to provide a relative moisture barrier during rain. Roof design evolved around 1850 in the American Southwest. Three inches of adobe mud was applied on top of the latillas, then 18 inches of dry adobe dirt applied to the roof. The dirt was contoured into a low slope to a downspout aka a 'canal'. When moisture was applied to the roof the clay particles expanded to create a waterproof membrane. Once a year it was necessary to pull the weeds from the roof and re-slope the dirt as needed. Depending on the materials, adobe roofs can be inherently fire-proof. The construction of a chimney can greatly influence the construction of the roof supports, creating an extra need for care in choosing the materials. The builders can make an adobe chimney by stacking simple adobe bricks in a similar fashion as the surrounding walls. In 1927, the Uniform Building Code (UBC) was adopted in the United States. Local ordinances, referencing the UBC added requirements to building with adobe. These included: restriction of building height of adobe structures to 1-story, requirements for adobe mix (compressive and shear strength) and new requirements which stated that every building shall be designed to withstand seismic activity, specifically lateral forces.

Adventure An adventure is an exciting experience or undertaking that is typically bold, sometimes risky. Adventures may be activities with some potential for physical danger such as traveling, exploring, skydiving, mountain climbing, scuba diving, river rafting or participating in extreme sports. Adventures are often undertaken to create psychological arousal or in order to achieve a greater goal such as the pursuit of knowledge that can only be obtained in a risky manner. Motivation Adventurous experiences create psychological arousal, which can be interpreted as negative (e.g. fear) or positive (e.g. flow). For some people, adventure becomes a major pursuit in and of itself. According to adventurer André Malraux, in his La Condition Humaine (1933), "If a man is not ready to risk his life, where is his dignity?". Similarly, Helen Keller stated that "Life is either a daring adventure or nothing." Outdoor adventurous activities are typically undertaken for the purposes of recreation or excitement: examples are adventure racing and adventure tourism. Adventurous activities can also lead to gains in knowledge, such as those undertaken by explorers and pioneers – the British adventurer Jason Lewis, for example, uses adventures to draw global sustainability lessons from living within finite environmental constraints on expeditions to share with schoolchildren. Adventure education intentionally uses challenging experiences for learning. Author Jon Levy suggests that an experience should meet several criteria to be considered an adventure: Be remarkable—that is, worth talking about Involve adversity or perceived risk Bring about personal growth Mythology and fiction Some of the oldest and most widespread stories in the world are stories of adventure such as Homer's The Odyssey. The knight errant was the form the "adventure seeker" character took in the late Middle Ages. The adventure novel exhibits these "protagonist on adventurous journey" characteristics as do many popular feature films, such as Star Wars and Raiders of the Lost Ark. Outdoors Adventure books may have the theme of the hero or main character going to face the wilderness or Mother Nature. Examples include books such as Hatchet or My Side of the Mountain. These books are less about "questing", such as in mythology or other adventure novels, but more about surviving on their own, living off the land, gaining new experiences, and becoming closer to the natural world. Questing Many adventures are based on the idea of a quest: the hero goes off in pursuit of a reward, whether it be a skill, prize, treasure, or perhaps the safety of a person. On the way, the hero must overcome various obstacles to obtain their reward. Video games In video-game culture, an adventure game is a video game in which the player assumes the role of a protagonist in an interactive story driven by exploration and puzzle-solving. The genre's focus on story allows it to draw heavily from other narrative-based media, literature and film, encompassing a wide variety of literary genres.

Many adventure games (text and graphic) are designed for a single player, since this emphasis on story and character makes multi-player design difficult. Nonfiction works From ancient times, travelers and explorers have written about their adventures. Journals which became best-sellers in their day were written, such as Marco Polo's journal The Travels of Marco Polo or Mark Twain's Roughing It. Others were personal journals, only later published, such as the journals of Lewis and Clark or Captain James Cook's journals. There are also books written by those not directly a part of the adventure in question, such as The Right Stuff by Tom Wolfe or books written by those participating in the adventure but in a format other than that of a journal, such as Conquistadors of the Useless by Lionel Terray. Documentaries often use the theme of adventure as well. Adventure sports There are many sports classified as adventure games or sports, due to their inherent danger and excitement. Some of these include mountain climbing, skydiving, or other extreme sports.Adventure sports has fast caught up in the Indian milieu. India offers immense opportunity for adventure lovers throughout its length and breadth. Angling & Fishing are two remarkable adventure activities among the many others that are offered in India. They are specially suited to the Indian subcontinent because of innumerable rivers that course through the expansive Gangetic Plains, and originate in the upper reaches of the magnificent Himalayas. The Indian Himalaya are an ultimate destination for adventure lovers and has attracted trekkers and lovers of nature Indian himalayas are the source of significant life giver rivers, like Ganges Beas, Satluj and their tributaries. The Himalayan mountain ranges of India offer breathtaking, highly challenging trekking routes. Mountaineering in India was introduced by the Europeans in the 18th century. India offers an exciting mountaineering experience to an adventure sport lover. The Himalayas that stretch from north-west of India to far north-east offers a number of high rise peaks that are considered ideal for mountaineering. Some of the places for mountaineering in India are Leh Ladakh in Jammu and Kashmir, Garhwal and Kumaon Himalayas in Uttarakhand, Kullu valley and Lahul Spiti in Himachal Pradesh, and Sikkim and some other parts of north-eastern region.

Asia Asia () is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. It shares the continental landmass of Eurasia with the continent of Europe, and the continental landmass of Afro-Eurasia with Africa and Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constituting roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, and ethnic differences, some of which vary on a spectrum rather than with a sharp dividing line. The most commonly accepted boundaries place Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish Straits, the Ural Mountains and Ural River, and to the south of the Caucasus Mountains and the Caspian and Black Seas, separating it from Europe. China and India alternated in being the largest economies in the world from 1 to 1800 CE. China was a major economic power and attracted many to the east, and for many the legendary wealth and prosperity of the ancient culture of India personified Asia, attracting European commerce, exploration and colonialism. The accidental discovery of a trans-Atlantic route from Europe to America by Columbus while in search for a route to India demonstrates this deep fascination. The Silk Road became the main east–west trading route in the Asian hinterlands while the Straits of Malacca stood as a major sea route. Asia has exhibited economic dynamism (particularly East Asia) as well as robust population growth during the 20th century, but overall population growth has since fallen. Asia was the birthplace of most of the world's mainstream religions including Hinduism, Zoroastrianism, Judaism, Jainism, Buddhism, Confucianism, Taoism, Christianity, Islam, Sikhism, as well as many other religions. Given its size and diversity, the concept of Asia—a name dating back to classical antiquity—may actually have more to do with human geography than physical geography. Asia varies greatly across and within its regions with regard to ethnic groups, cultures, environments, economics, historical ties and government systems. It also has a mix of many different climates ranging from the equatorial south via the hot desert in the Middle East, temperate areas in the east and the continental centre to vast subarctic and polar areas in Siberia. Definition and boundaries Asia–Africa boundary The boundary between Asia and Africa is the Red Sea, the Gulf of Suez, and the Suez Canal.

Definition and boundaries Asia–Africa boundary The boundary between Asia and Africa is the Red Sea, the Gulf of Suez, and the Suez Canal.

This makes Egypt a transcontinental country, with the Sinai peninsula in Asia and the remainder of the country in Africa. Asia–Europe boundary The threefold division of the Old World into Europe, Asia and Africa has been in use since the 6th century BC, due to Greek geographers such as Anaximander and Hecataeus. Anaximander placed the boundary between Asia and Europe along the Phasis River (the modern Rioni river) in Georgia of Caucasus (from its mouth by Poti on the Black Sea coast, through the Surami Pass and along the Kura River to the Caspian Sea), a convention still followed by Herodotus in the 5th century BC. During the Hellenistic period, this convention was revised, and the boundary between Europe and Asia was now considered to be the Tanais (the modern Don River). This is the convention used by Roman era authors such as Posidonius, Strabo and Ptolemy. The border between Asia and Europe was historically defined by European academics. The Don River became unsatisfactory to northern Europeans when Peter the Great, king of the Tsardom of Russia, defeating rival claims of Sweden and the Ottoman Empire to the eastern lands, and armed resistance by the tribes of Siberia, synthesized a new Russian Empire extending to the Ural Mountains and beyond, founded in 1721. The major geographical theorist of the empire was a former Swedish prisoner-of-war, taken at the Battle of Poltava in 1709 and assigned to Tobolsk, where he associated with Peter's Siberian official, Vasily Tatishchev, and was allowed freedom to conduct geographical and anthropological studies in preparation for a future book. In Sweden, five years after Peter's death, in 1730 Philip Johan von Strahlenberg published a new atlas proposing the Ural Mountains as the border of Asia. Tatishchev announced that he had proposed the idea to von Strahlenberg. The latter had suggested the Emba River as the lower boundary. Over the next century various proposals were made until the Ural River prevailed in the mid-19th century. The border had been moved perforce from the Black Sea to the Caspian Sea into which the Ural River projects. The border between the Black Sea and the Caspian is usually placed along the crest of the Caucasus Mountains, although it is sometimes placed further north. Asia–Oceania boundary The border between Asia and the region of Oceania is usually placed somewhere in the Malay Archipelago. The Maluku Islands in Indonesia are often considered to lie on the border of southeast Asia, with New Guinea, to the east of the islands, being wholly part of Oceania. The terms Southeast Asia and Oceania, devised in the 19th century, have had several vastly different geographic meanings since their inception. The chief factor in determining which islands of the Malay Archipelago are Asian has been the location of the colonial possessions of the various empires there (not all European). Lewis and Wigen assert, "The narrowing of 'Southeast Asia' to its present boundaries was thus a gradual process."

Ongoing definition Geographical Asia is a cultural artifact of European conceptions of the world, beginning with the Ancient Greeks, being imposed onto other cultures, an imprecise concept causing endemic contention about what it means. Asia does not exactly correspond to the cultural borders of its various types of constituents. From the time of Herodotus a minority of geographers have rejected the three-continent system (Europe, Africa, Asia) on the grounds that there is no substantial physical separation between them. For example, Sir Barry Cunliffe, the emeritus professor of European archeology at Oxford, argues that Europe has been geographically and culturally merely "the western excrescence of the continent of Asia". Geographically, Asia is the major eastern constituent of the continent of Eurasia with Europe being a northwestern peninsula of the landmass. Asia, Europe and Africa make up a single continuous landmass—Afro-Eurasia (except for the Suez Canal)—and share a common continental shelf. Almost all of Europe and a major part of Asia sit atop the Eurasian Plate, adjoined on the south by the Arabian and Indian Plate and with the easternmost part of Siberia (east of the Chersky Range) on the North American Plate. Etymology The idea of a place called "Asia" was originally a concept of Greek civilization, though this might not correspond to the entire continent currently known by that name. The English word comes from Latin literature, where it has the same form, "Asia". Whether "Asia" in other languages comes from Latin of the Roman Empire is much less certain, and the ultimate source of the Latin word is uncertain, though several theories have been published. One of the first classical writers to use Asia as a name of the whole continent was Pliny. This metonymical change in meaning is common and can be observed in some other geographical names, such as Scandinavia (from Scania). Bronze Age Before Greek poetry, the Aegean Sea area was in a Greek Dark Age, at the beginning of which syllabic writing was lost and alphabetic writing had not begun. Prior to then in the Bronze Age the records of the Assyrian Empire, the Hittite Empire and the various Mycenaean states of Greece mention a region undoubtedly Asia, certainly in Anatolia, including if not identical to Lydia. These records are administrative and do not include poetry. The Mycenaean states were destroyed about 1200 BCE by unknown agents, though one school of thought assigns the Dorian invasion to this time. The burning of the palaces caused the clay tablets holding the Mycenaean administrative records to be preserved by baking. These tablets were written in a Greek syllabic script called Linear B. This script was deciphered by a number of interested parties, most notably by a young World War II cryptographer, Michael Ventris, subsequently assisted by the scholar, John Chadwick. A major cache discovered by Carl Blegen at the site of ancient Pylos included hundreds of male and female names formed by different methods.

This metonymical change in meaning is common and can be observed in some other geographical names, such as Scandinavia (from Scania). Bronze Age Before Greek poetry, the Aegean Sea area was in a Greek Dark Age, at the beginning of which syllabic writing was lost and alphabetic writing had not begun. Prior to then in the Bronze Age the records of the Assyrian Empire, the Hittite Empire and the various Mycenaean states of Greece mention a region undoubtedly Asia, certainly in Anatolia, including if not identical to Lydia. These records are administrative and do not include poetry. The Mycenaean states were destroyed about 1200 BCE by unknown agents, though one school of thought assigns the Dorian invasion to this time. The burning of the palaces caused the clay tablets holding the Mycenaean administrative records to be preserved by baking. These tablets were written in a Greek syllabic script called Linear B. This script was deciphered by a number of interested parties, most notably by a young World War II cryptographer, Michael Ventris, subsequently assisted by the scholar, John Chadwick. A major cache discovered by Carl Blegen at the site of ancient Pylos included hundreds of male and female names formed by different methods.

Ongoing definition Geographical Asia is a cultural artifact of European conceptions of the world, beginning with the Ancient Greeks, being imposed onto other cultures, an imprecise concept causing endemic contention about what it means. Asia does not exactly correspond to the cultural borders of its various types of constituents. From the time of Herodotus a minority of geographers have rejected the three-continent system (Europe, Africa, Asia) on the grounds that there is no substantial physical separation between them. For example, Sir Barry Cunliffe, the emeritus professor of European archeology at Oxford, argues that Europe has been geographically and culturally merely "the western excrescence of the continent of Asia". Geographically, Asia is the major eastern constituent of the continent of Eurasia with Europe being a northwestern peninsula of the landmass. Asia, Europe and Africa make up a single continuous landmass—Afro-Eurasia (except for the Suez Canal)—and share a common continental shelf. Almost all of Europe and a major part of Asia sit atop the Eurasian Plate, adjoined on the south by the Arabian and Indian Plate and with the easternmost part of Siberia (east of the Chersky Range) on the North American Plate. Etymology The idea of a place called "Asia" was originally a concept of Greek civilization, though this might not correspond to the entire continent currently known by that name. The English word comes from Latin literature, where it has the same form, "Asia". Whether "Asia" in other languages comes from Latin of the Roman Empire is much less certain, and the ultimate source of the Latin word is uncertain, though several theories have been published.

Some of these are of women held in servitude (as study of the society implied by the content reveals). They were used in trades, such as cloth-making, and usually came with children. The epithet lawiaiai, "captives", associated with some of them identifies their origin. Some are ethnic names. One in particular, aswiai, identifies "women of Asia". Perhaps they were captured in Asia, but some others, Milatiai, appear to have been of Miletus, a Greek colony, which would not have been raided for slaves by Greeks. Chadwick suggests that the names record the locations where these foreign women were purchased. The name is also in the singular, Aswia, which refers both to the name of a country and to a female from there. There is a masculine form, . This Aswia appears to have been a remnant of a region known to the Hittites as Assuwa, centered on Lydia, or "Roman Asia". This name, Assuwa, has been suggested as the origin for the name of the continent "Asia". The Assuwa league was a confederation of states in western Anatolia, defeated by the Hittites under Tudhaliya I around 1400 BCE. Classical antiquity Latin Asia and Greek Ἀσία appear to be the same word. Roman authors translated Ἀσία as Asia. The Romans named a province Asia, located in western Anatolia (in modern-day Turkey). There was an Asia Minor and an Asia Major located in modern-day Iraq. As the earliest evidence of the name is Greek, it is likely circumstantially that Asia came from Ἀσία, but ancient transitions, due to the lack of literary contexts, are difficult to catch in the act. The most likely vehicles were the ancient geographers and historians, such as Herodotus, who were all Greek. Ancient Greek certainly evidences early and rich uses of the name. The first continental use of Asia is attributed to Herodotus (about 440 BCE), not because he innovated it, but because his Histories are the earliest surviving prose to describe it in any detail. He defines it carefully, mentioning the previous geographers whom he had read, but whose works are now missing. By it he means Anatolia and the Persian Empire, in contrast to Greece and Egypt. Herodotus comments that he is puzzled as to why three women's names were "given to a tract which is in reality one" (Europa, Asia, and Libya, referring to Africa), stating that most Greeks assumed that Asia was named after the wife of Prometheus (i.e. Hesione), but that the Lydians say it was named after Asies, son of Cotys, who passed the name on to a tribe at Sardis. In Greek mythology, "Asia" (Ἀσία) or "Asie" (Ἀσίη) was the name of a "Nymph or Titan goddess of Lydia". In ancient Greek religion, places were under the care of female divinities, parallel to guardian angels. The poets detailed their doings and generations in allegoric language salted with entertaining stories, which subsequently playwrights transformed into classical Greek drama and became "Greek mythology".

For example, Hesiod mentions the daughters of Tethys and Ocean, among whom are a "holy company", "who with the Lord Apollo and the Rivers have youths in their keeping". Many of these are geographic: Doris, Rhodea, Europa, Asia. Hesiod explains: The Iliad (attributed by the ancient Greeks to Homer) mentions two Phrygians (the tribe that replaced the Luvians in Lydia) in the Trojan War named Asios (an adjective meaning "Asian"); and also a marsh or lowland containing a marsh in Lydia as . According to many Muslims, the term came from Ancient Egypt's Queen Asiya, the adoptive mother of Moses. History The history of Asia can be seen as the distinct histories of several peripheral coastal regions: East Asia, South Asia, Southeast Asia and the Middle East, linked by the interior mass of the Central Asian steppes. The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands. The central steppe region had long been inhabited by horse-mounted nomads who could reach all areas of Asia from the steppes. The earliest postulated expansion out of the steppe is that of the Indo-Europeans, who spread their languages into the Middle East, South Asia, and the borders of China, where the Tocharians resided. The northernmost part of Asia, including much of Siberia, was largely inaccessible to the steppe nomads, owing to the dense forests, climate and tundra. These areas remained very sparsely populated. The center and the peripheries were mostly kept separated by mountains and deserts. The Caucasus and Himalaya mountains and the Karakum and Gobi deserts formed barriers that the steppe horsemen could cross only with difficulty. While the urban city dwellers were more advanced technologically and socially, in many cases they could do little in a military aspect to defend against the mounted hordes of the steppe. However, the lowlands did not have enough open grasslands to support a large horsebound force; for this and other reasons, the nomads who conquered states in China, India, and the Middle East often found themselves adapting to the local, more affluent societies. The Islamic Caliphate's defeats of the Byzantine and Persian empires led to West Asia and southern parts of Central Asia and western parts of South Asia under its control during its conquests of the 7th century. The Mongol Empire conquered a large part of Asia in the 13th century, an area extending from China to Europe. Before the Mongol invasion, Song dynasty reportedly had approximately 120 million citizens; the 1300 census which followed the invasion reported roughly 60 million people.

The Black Death, one of the most devastating pandemics in human history, is thought to have originated in the arid plains of central Asia, where it then travelled along the Silk Road. The Russian Empire began to expand into Asia from the 17th century, and would eventually take control of all of Siberia and most of Central Asia by the end of the 19th century. The Ottoman Empire controlled Anatolia, most of the Middle East, North Africa and the Balkans from the mid 16th century onwards. In the 17th century, the Manchu conquered China and established the Qing dynasty. The Islamic Mughal Empire and the Hindu Maratha Empire controlled much of India in the 16th and 18th centuries respectively. The Empire of Japan controlled most of East Asia and much of Southeast Asia, New Guinea and the Pacific islands until the end of World War II. Geography and climate Asia is the largest continent on Earth. It covers 9% of the Earth's total surface area (or 30% of its land area), and has the longest coastline, at . Asia is generally defined as comprising the eastern four-fifths of Eurasia. It is located to the east of the Suez Canal and the Ural Mountains, and south of the Caucasus Mountains (or the Kuma–Manych Depression) and the Caspian and Black Seas. It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean. Asia is subdivided into 49 countries, five of them (Georgia, Azerbaijan, Russia, Kazakhstan and Turkey) are transcontinental countries lying partly in Europe. Geographically, Russia is partly in Asia, but is considered a European nation, both culturally and politically. The Gobi Desert is in Mongolia and the Arabian Desert stretches across much of the Middle East. The Yangtze River in China is the longest river in the continent. The Himalayas between Nepal and China is the tallest mountain range in the world. Tropical rainforests stretch across much of southern Asia and coniferous and deciduous forests lie farther north. Main regions There are various approaches to the regional division of Asia. The following subdivision into regions is used, among others, by the UN statistics agency UNSD. This division of Asia into regions by the United Nations is done solely for statistical reasons and does not imply any assumption about political or other affiliations of countries and territories. North Asia (Siberia) Central Asia (The 'stans) Western Asia (The Middle East or Near East) South Asia (Indian subcontinent) East Asia (Far East) Southeast Asia (East Indies and Indochina) Climate Asia has extremely diverse climate features. Climates range from arctic and subarctic in Siberia to tropical in southern India and Southeast Asia. It is moist across southeast sections, and dry across much of the interior. Some of the largest daily temperature ranges on Earth occur in western sections of Asia.

Some of the largest daily temperature ranges on Earth occur in western sections of Asia.

The monsoon circulation dominates across southern and eastern sections, due to the presence of the Himalayas forcing the formation of a thermal low which draws in moisture during the summer. Southwestern sections of the continent are hot. Siberia is one of the coldest places in the Northern Hemisphere, and can act as a source of arctic air masses for North America. The most active place on Earth for tropical cyclone activity lies northeast of the Philippines and south of Japan. A survey carried out in 2010 by global risk analysis farm Maplecroft identified 16 countries that are extremely vulnerable to climate change. Each nation's vulnerability was calculated using 42 socio, economic and environmental indicators, which identified the likely climate change impacts during the next 30 years. The Asian countries of Bangladesh, India, the Philippines, Vietnam, Thailand, Pakistan, China and Sri Lanka were among the 16 countries facing extreme risk from climate change. Some shifts are already occurring. For example, in tropical parts of India with a semi-arid climate, the temperature increased by 0.4 °C between 1901 and 2003. A 2013 study by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) aimed to find science-based, pro-poor approaches and techniques that would enable Asia's agricultural systems to cope with climate change, while benefitting poor and vulnerable farmers. The study's recommendations ranged from improving the use of climate information in local planning and strengthening weather-based agro-advisory services, to stimulating diversification of rural household incomes and providing incentives to farmers to adopt natural resource conservation measures to enhance forest cover, replenish groundwater and use renewable energy. The ten countries of the Association of Southeast Asian Nations (ASEAN) - Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam - are among the most vulnerable to the effects of climate change in the world, however, ASEAN's climate mitigation efforts are not commensurate with the climate threats and risks it faces. Economy Asia has the largest continental economy by both GDP Nominal and PPP in the world, and is the fastest growing economic region. , the largest economies in Asia are China, Japan, India, South Korea, Indonesia and Turkey based on GDP in both nominal and PPP. Based on Global Office Locations 2011, Asia dominated the office locations with 4 of the top 5 being in Asia: Hong Kong, Singapore, Tokyo and Seoul. Around 68 percent of international firms have an office in Hong Kong. In the late 1990s and early 2000s, the economies of China and India have been growing rapidly, both with an average annual growth rate of more than 8%. Other recent very-high-growth nations in Asia include Israel, Malaysia, Indonesia, Bangladesh, Thailand, Vietnam, and the Philippines, and mineral-rich nations such as Kazakhstan, Turkmenistan, Iran, Brunei, the United Arab Emirates, Qatar, Kuwait, Saudi Arabia, Bahrain and Oman. According to economic historian Angus Maddison in his book The World Economy: A Millennial Perspective, India had the world's largest economy during 0 BCE and 1000 BCE.

Southwestern sections of the continent are hot. Siberia is one of the coldest places in the Northern Hemisphere, and can act as a source of arctic air masses for North America. The most active place on Earth for tropical cyclone activity lies northeast of the Philippines and south of Japan. A survey carried out in 2010 by global risk analysis farm Maplecroft identified 16 countries that are extremely vulnerable to climate change. Each nation's vulnerability was calculated using 42 socio, economic and environmental indicators, which identified the likely climate change impacts during the next 30 years. The Asian countries of Bangladesh, India, the Philippines, Vietnam, Thailand, Pakistan, China and Sri Lanka were among the 16 countries facing extreme risk from climate change. Some shifts are already occurring. For example, in tropical parts of India with a semi-arid climate, the temperature increased by 0.4 °C between 1901 and 2003. A 2013 study by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) aimed to find science-based, pro-poor approaches and techniques that would enable Asia's agricultural systems to cope with climate change, while benefitting poor and vulnerable farmers. The study's recommendations ranged from improving the use of climate information in local planning and strengthening weather-based agro-advisory services, to stimulating diversification of rural household incomes and providing incentives to farmers to adopt natural resource conservation measures to enhance forest cover, replenish groundwater and use renewable energy. The ten countries of the Association of Southeast Asian Nations (ASEAN) - Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam - are among the most vulnerable to the effects of climate change in the world, however, ASEAN's climate mitigation efforts are not commensurate with the climate threats and risks it faces. Economy Asia has the largest continental economy by both GDP Nominal and PPP in the world, and is the fastest growing economic region. , the largest economies in Asia are China, Japan, India, South Korea, Indonesia and Turkey based on GDP in both nominal and PPP. Based on Global Office Locations 2011, Asia dominated the office locations with 4 of the top 5 being in Asia: Hong Kong, Singapore, Tokyo and Seoul. Around 68 percent of international firms have an office in Hong Kong. In the late 1990s and early 2000s, the economies of China and India have been growing rapidly, both with an average annual growth rate of more than 8%. Other recent very-high-growth nations in Asia include Israel, Malaysia, Indonesia, Bangladesh, Thailand, Vietnam, and the Philippines, and mineral-rich nations such as Kazakhstan, Turkmenistan, Iran, Brunei, the United Arab Emirates, Qatar, Kuwait, Saudi Arabia, Bahrain and Oman. According to economic historian Angus Maddison in his book The World Economy: A Millennial Perspective, India had the world's largest economy during 0 BCE and 1000 BCE.

Historically, India was the largest economy in the world for most of the two millennia from the 1st until 19th century, contributing 25% of the world's industrial output. China was the largest and most advanced economy on earth for much of recorded history and shared the mantle with India. For several decades in the late twentieth century Japan was the largest economy in Asia and second-largest of any single nation in the world, after surpassing the Soviet Union (measured in net material product) in 1990 and Germany in 1968. (NB: A number of supernational economies are larger, such as the European Union (EU), the North American Free Trade Agreement (NAFTA) or APEC). This ended in 2010 when China overtook Japan to become the world's second largest economy. In the late 1980s and early 1990s, Japan's GDP was almost as large (current exchange rate method) as that of the rest of Asia combined. In 1995, Japan's economy nearly equaled that of the US as the largest economy in the world for a day, after the Japanese currency reached a record high of 79 yen/US$. Economic growth in Asia since World War II to the 1990s had been concentrated in Japan as well as the four regions of South Korea, Taiwan, Hong Kong and Singapore located in the Pacific Rim, known as the Asian tigers, which have now all received developed country status, having the highest GDP per capita in Asia. It is forecasted that India will overtake Japan in terms of nominal GDP by 2025. By 2027, according to Goldman Sachs, China will have the largest economy in the world. Several trade blocs exist, with the most developed being the Association of Southeast Asian Nations. Asia is the largest continent in the world by a considerable margin, and it is rich in natural resources, such as petroleum, forests, fish, water, rice, copper and silver. Manufacturing in Asia has traditionally been strongest in East and Southeast Asia, particularly in China, Taiwan, South Korea, Japan, India, the Philippines, and Singapore. Japan and South Korea continue to dominate in the area of multinational corporations, but increasingly the PRC and India are making significant inroads. Many companies from Europe, North America, South Korea and Japan have operations in Asia's developing countries to take advantage of its abundant supply of cheap labour and relatively developed infrastructure. According to Citigroup 9 of 11 Global Growth Generators countries came from Asia driven by population and income growth. They are Bangladesh, China, India, Indonesia, Iraq, Mongolia, the Philippines, Sri Lanka and Vietnam. Asia has three main financial centers: Hong Kong, Tokyo and Singapore. Call centers and business process outsourcing (BPOs) are becoming major employers in India and the Philippines due to the availability of a large pool of highly skilled, English-speaking workers. The increased use of outsourcing has assisted the rise of India and the China as financial centers. Due to its large and extremely competitive information technology industry, India has become a major hub for outsourcing.

Trade between Asian countries and countries on other continents is largely carried out on the sea routes that are important for Asia. Individual main routes have emerged from this. The main route leads from the Chinese coast south via Hanoi to Jakarta, Singapore and Kuala Lumpur through the Strait of Malacca via the Sri Lankan Colombo to the southern tip of India via Malé to East Africa Mombasa, from there to Djibouti, then through the Red Sea over the Suez Canal into Mediterranean, there via Haifa, Istanbul and Athens to the upper Adriatic to the northern Italian hub of Trieste with its rail connections to Central and Eastern Europe or further to Barcelona and around Spain and France to the European northern ports. A far smaller part of the goods traffic runs via South Africa to Europe. A particularly significant part of the Asian goods traffic is carried out across the Pacific towards Los Angeles and Long Beach. In contrast to the sea routes, the Silk Road via the land route to Europe is on the one hand still under construction and on the other hand is much smaller in terms of scope. Intra-Asian trade, including sea trade, is growing rapidly. In 2010, Asia had 3.3 million millionaires (people with net worth over US$1 million excluding their homes), slightly below North America with 3.4 million millionaires. Last year Asia had toppled Europe. Citigroup in The Wealth Report 2012 stated that Asian centa-millionaire overtook North America's wealth for the first time as the world's "economic center of gravity" continued moving east. At the end of 2011, there were 18,000 Asian people mainly in Southeast Asia, China and Japan who have at least $100 million in disposable assets, while North America with 17,000 people and Western Europe with 14,000 people. Tourism With growing Regional Tourism with domination of Chinese visitors, MasterCard has released Global Destination Cities Index 2013 with 10 of 20 are dominated by Asia and Pacific Region Cities and also for the first time a city of a country from Asia (Bangkok) set in the top-ranked with 15.98 international visitors. Demographics East Asia had by far the strongest overall Human Development Index (HDI) improvement of any region in the world, nearly doubling average HDI attainment over the past 40 years, according to the report's analysis of health, education and income data. China, the second highest achiever in the world in terms of HDI improvement since 1970, is the only country on the "Top 10 Movers" list due to income rather than health or education achievements. Its per capita income increased a stunning 21-fold over the last four decades, also lifting hundreds of millions out of income poverty. Yet it was not among the region's top performers in improving school enrollment and life expectancy. Nepal, a South Asian country, emerges as one of the world's fastest movers since 1970 mainly due to health and education achievements. Its present life expectancy is 25 years longer than in the 1970s.

More than four of every five children of school age in Nepal now attend primary school, compared to just one in five 40 years ago. Hong Kong ranked highest among the countries grouped on the HDI (number 7 in the world, which is in the "very high human development" category), followed by Singapore (9), Japan (19) and South Korea (22). Afghanistan (155) ranked lowest amongst Asian countries out of the 169 countries assessed. Languages Asia is home to several language families and many language isolates. Most Asian countries have more than one language that is natively spoken. For instance, according to Ethnologue, more than 600 languages are spoken in Indonesia, more than 800 languages spoken in India, and more than 100 are spoken in the Philippines. China has many languages and dialects in different provinces. Religions Many of the world's major religions have their origins in Asia, including the five most practiced in the world (excluding irreligion), which are Christianity, Islam, Hinduism, Chinese folk religion (classified as Confucianism and Taoism), and Buddhism respectively. Asian mythology is complex and diverse. The story of the Great Flood for example, as presented to Jews in the Hebrew Bible in the narrative of Noah—and later to Christians in the Old Testament, and to Muslims in the Quran—is earliest found in Mesopotamian mythology, in the Enûma Eliš and Epic of Gilgamesh. Hindu mythology similarly tells about an avatar of Vishnu in the form of a fish who warned Manu of a terrible flood. Ancient Chinese mythology also tells of a Great Flood spanning generations, one that required the combined efforts of emperors and divinities to control. Abrahamic The Abrahamic religions including Judaism, Christianity, Islam, Druze faith, and Baháʼí Faith originated in West Asia. Judaism, the oldest of the Abrahamic faiths, is practiced primarily in Israel, the indigenous homeland and historical birthplace of the Hebrew nation: which today consists both of those Jews who remained in the Middle East and those who returned from diaspora in Europe, North America, and other regions; though various diaspora communities persist worldwide. Jews are the predominant ethnic group in Israel (75.6%) numbering at about 6.1 million, although the levels of adherence to Jewish religion vary. Outside of Israel there are small ancient Jewish communities in Turkey (17,400), Azerbaijan (9,100), Iran (8,756), India (5,000) and Uzbekistan (4,000), among many other places. In total, there are 14.4–17.5 million (2016, est.) Jews alive in the world today, making them one of the smallest Asian minorities, at roughly 0.3 to 0.4 percent of the total population of the continent. Christianity is a widespread religion in Asia with more than 286 million adherents according to Pew Research Center in 2010, and nearly 364 million according to Britannica Book of the Year 2014. Constituting around 12.6% of the total population of Asia. In the Philippines and East Timor, Roman Catholicism is the predominant religion; it was introduced by the Spaniards and the Portuguese, respectively. In Armenia and Georgia, Eastern Orthodoxy is the predominant religion.

In Armenia and Georgia, Eastern Orthodoxy is the predominant religion.

In the Middle East, such as in the Levant, Anatolia and Fars, Syriac Christianity (Church of the East) and Oriental Orthodoxy are prevalent minority denominations, which are both Eastern Christian sects mainly adhered to Assyrian people or Syriac Christians. Vibrant indigenous minorities in Western Asia are adhering to the Eastern Catholic Churches and Eastern Orthodoxy. Saint Thomas Christians in India trace their origins to the evangelistic activity of Thomas the Apostle in the 1st century. Significant Christian communities also found in Central Asia, South Asia, Southeast Asia and East Asia. Islam, which originated in the Hejaz located in modern-day Saudi Arabia, is the second largest and most widely-spread religion in Asia with at least 1 billion Muslims constituting around 23.8% of the total population of Asia. With 12.7% of the world Muslim population, the country currently with the largest Muslim population in the world is Indonesia, followed by Pakistan (11.5%), India (10%), Bangladesh, Iran and Turkey. Mecca, Medina and Jerusalem are the three holiest cities for Islam in all the world. The Hajj and Umrah attract large numbers of Muslim devotees from all over the world to Mecca and Medina. Iran is the largest Shi'a country. The Druze Faith or Druzism originated in Western Asia, is a monotheistic religion based on the teachings of figures like Hamza ibn-'Ali ibn-Ahmad and Al-Hakim bi-Amr Allah, and Greek philosophers such as Plato and Aristotle. The number of Druze people worldwide is around one million, with about 45% to 50% live in Syria, 35% to 40% live in Lebanon, and less than 10% live in Israel, with recently there has been a growing Druze diaspora. The Baháʼí Faith originated in Asia, in Iran (Persia), and spread from there to the Ottoman Empire, Central Asia, India, and Burma during the lifetime of Bahá'u'lláh. Since the middle of the 20th century, growth has particularly occurred in other Asian countries, because Baháʼí activities in many Muslim countries has been severely suppressed by authorities. Lotus Temple is a big Baháʼí Temple in India. Indian and East Asian religions Almost all Asian religions have philosophical character and Asian philosophical traditions cover a large spectrum of philosophical thoughts and writings. Indian philosophy includes Hindu philosophy and Buddhist philosophy. They include elements of nonmaterial pursuits, whereas another school of thought from India, Cārvāka, preached the enjoyment of the material world. The religions of Hinduism, Buddhism, Jainism and Sikhism originated in India, South Asia. In East Asia, particularly in China and Japan, Confucianism, Taoism and Zen Buddhism took shape. , Hinduism has around 1.1 billion adherents. The faith represents around 25% of Asia's population and is the largest religion in Asia. However, it is mostly concentrated in South Asia. Over 80% of the populations of both India and Nepal adhere to Hinduism, alongside significant communities in Bangladesh, Pakistan, Bhutan, Sri Lanka and Bali, Indonesia. Many overseas Indians in countries such as Burma, Singapore and Malaysia also adhere to Hinduism. Buddhism has a great following in mainland Southeast Asia and East Asia.

Aruba Aruba ( , , ) is a constituent country of the Kingdom of the Netherlands physically located in the mid-south of the Caribbean Sea, about north of the Venezuelan peninsula of Paraguaná and northwest of Curaçao. It measures long from its northwestern to its southeastern end and across at its widest point. Together with Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands. Collectively, these and the other three Dutch substantial islands in the Caribbean are often called the Dutch Caribbean, of which Aruba has about one-third of the population. In 1986, it became a constituent country within the Kingdom of the Netherlands, and acquired the formal name the Country of Aruba. Aruba is one of the four countries that form the Kingdom of the Netherlands, along with the Netherlands, Curaçao, and Sint Maarten; the citizens of these countries are all Dutch nationals. Aruba has no administrative subdivisions, but, for census purposes, is divided into eight regions. Its capital is Oranjestad. Unlike much of the Caribbean region, Aruba has a dry climate and an arid, cactus-strewn landscape. The climate has helped tourism, because visitors to the island can expect clear, sunny skies all year. Its area is and it is quite densely populated, with 101,484 inhabitants as at the 2010 Census. A January 2019 estimate of the population placed it at 116,600. Etymology The name Aruba most likely came from the Caquetio Oruba which means "Well situated island", seeing as it was the Caquetio who were present on the island when it was first colonised by Alonso de Ojeda. as of 1529 the name "Isla de Oruba" was used for the island by the Spanish until the Treaty of Westphalia, when the island was ceded to the Dutch and its name was changed to Aruba. There were many different names for Aruba used by other Amerindian groups, all of which could have contributed to the present-day name Aruba. Another Caquetio name for the island was Oibubia which means "Guided island". The Taino name for the island was Arubeira. The Kalinago also had two names for the island Ora Oubao which means "Shell island" and Oirubae which means "Companion of Curaçao". A common misconception is that the name Aruba came from the Spanish Oro hubo which means "There was gold". However the Spanish found no gold on Aruba during the time of their occupation, nicknaming Aruba and the rest of the ABC islands Islas Inútiles, meaning "Useless islands" due to the lack of gold. It was not until much later in 1824 that gold was found on Aruba by Willem Rasmijn, staring the Aruban Gold Rush. Another early Spanish name for Aruba was Isla de Brasil, named as such because of the many Brazilwood trees that grew on the island. History Pre-colonial era There has been a human presence on Aruba from as early as circa 2000 BC. The first identifiable group are the Arawak Caquetío Amerindians who migrated from South America about 1000 AD.

Etymology The name Aruba most likely came from the Caquetio Oruba which means "Well situated island", seeing as it was the Caquetio who were present on the island when it was first colonised by Alonso de Ojeda. as of 1529 the name "Isla de Oruba" was used for the island by the Spanish until the Treaty of Westphalia, when the island was ceded to the Dutch and its name was changed to Aruba. There were many different names for Aruba used by other Amerindian groups, all of which could have contributed to the present-day name Aruba. Another Caquetio name for the island was Oibubia which means "Guided island". The Taino name for the island was Arubeira. The Kalinago also had two names for the island Ora Oubao which means "Shell island" and Oirubae which means "Companion of Curaçao". A common misconception is that the name Aruba came from the Spanish Oro hubo which means "There was gold". However the Spanish found no gold on Aruba during the time of their occupation, nicknaming Aruba and the rest of the ABC islands Islas Inútiles, meaning "Useless islands" due to the lack of gold. It was not until much later in 1824 that gold was found on Aruba by Willem Rasmijn, staring the Aruban Gold Rush. Another early Spanish name for Aruba was Isla de Brasil, named as such because of the many Brazilwood trees that grew on the island. History Pre-colonial era There has been a human presence on Aruba from as early as circa 2000 BC. The first identifiable group are the Arawak Caquetío Amerindians who migrated from South America about 1000 AD.

Archaeological evidence suggests continuing links between these native Arubans and Amerindian peoples of mainland South America. Spanish colonization The first Europeans to visit Aruba were Amerigo Vespucci and Alonso de Ojeda in 1499, who claimed the island for Spain. Both men described Aruba as an "island of giants", remarking on the comparatively large stature of the native Caquetíos. Vespucci returned to Spain with stocks of cotton and brazilwood from the island and described houses built into the ocean. Vespucci and Ojeda's tales spurred interest in Aruba, and the Spanish began colonising the island. Alonso de Ojeda was appointed the island's first governor in 1508. From 1513 the Spanish began enslaving the Caquetíos, sending many to a life of forced labour in the mines of Hispaniola. The island's low rainfall and arid landscape meant that it was not considered profitable for a slave-based plantation system, so the type of large-scale slavery so common on other Caribbean islands never became established on Aruba. Early Dutch period The Netherlands seized Aruba from Spain in 1636 in the course of the Thirty Years' War. Peter Stuyvesant, later appointed to New Amsterdam (New York), was the first Dutch governor. Those Arawak who had survived the depredations of the Spanish were allowed to farm and graze livestock, with the Dutch using the island as a source of meat for their other possessions in the Caribbean. Aruba's proximity to South America resulted in interactions with the cultures of the coastal areas; for example, architectural similarities can be seen between the 19th-century parts of Oranjestad and the nearby Venezuelan city of Coro in Falcón State. Historically, Dutch was not widely spoken on the island outside of colonial administration; its use increased in the late 19th and early 20th centuries. Students on Curaçao, Aruba, and Bonaire were taught predominantly in Spanish until the late 18th century. During the Napoleonic Wars, the British Empire took control of the island, occupying it between 1806 and 1816, before handing it back to the Dutch as per the terms of the Anglo-Dutch Treaty of 1814. Aruba subsequently became part of the Colony of Curaçao and Dependencies along with Bonaire. During the 19th century, an economy based on gold mining, phosphate production and aloe vera plantations developed, but the island remained a relatively poor backwater. 20th and 21st centuries The first oil refinery in Aruba was built in 1928 by Royal Dutch Shell. The facility was built just to the west of the capital city, Oranjestad, and was commonly called the Eagle. Immediately following that, another refinery was built by Lago Oil and Transport Company, in an area now known as San Nicolas on the east end of Aruba. The refineries processed crude oil from the vast Venezuelan oil fields, bringing greater prosperity to the island. The refinery on Aruba grew to become one of the largest in the world. During World War II, the Netherlands was occupied by Nazi Germany.

In 1940, the oil facilities in Aruba came under the administration of the Dutch government-in-exile in London, causing them to be attacked by the German navy in 1942. In August 1947, Aruba formulated its first Staatsreglement (constitution) for Aruba's status aparte as an autonomous state within the Kingdom of the Netherlands, prompted by the efforts of Henny Eman, a noted Aruban politician. By 1954, the Charter of the Kingdom of the Netherlands was established, providing a framework for relations between Aruba and the rest of the Kingdom. That created the Netherlands Antilles, which united all of the Dutch colonies in the Caribbean into one administrative structure. Many Arubans were unhappy with the arrangement, however, as the new polity was perceived as being dominated by Curaçao. In 1972, at a conference in Suriname, Betico Croes, a politician from Aruba, proposed the creation of a Dutch Commonwealth of four states: Aruba, the Netherlands, Suriname, and the Netherlands Antilles, each to have its own nationality. Backed by his newly created party, the Movimiento Electoral di Pueblo, Croes sought greater autonomy for Aruba, with the long-term goal of independence, adopting the trappings of an independent state in 1976 with the creation of a flag and national anthem. In March 1977, a referendum was held with the support of the United Nations. 82% of the participants voted for complete independence from the Netherlands. Tensions mounted as Croes stepped up the pressure on the Dutch government by organising a general strike in 1977. Croes later met with Dutch Prime Minister Joop den Uyl, with the two sides agreeing to assign the Institute of Social Studies in The Hague to prepare a study for independence, entitled Aruba en Onafhankelijkheid, achtergronden, modaliteiten, en mogelijkheden; een rapport in eerste aanleg (Aruba and independence, backgrounds, modalities, and opportunities; a preliminary report) (1978). Autonomy In March 1983, Aruba reached an official agreement within the Kingdom for its independence, to be developed in a series of steps as the Crown granted increasing autonomy. In August 1985, Aruba drafted a constitution that was unanimously approved. On 1 January 1986, after elections were held for its first parliament, Aruba seceded from the Netherlands Antilles, officially becoming a country of the Kingdom of the Netherlands, with full independence planned for 1996. However, Croes was seriously injured in a traffic accident in 1985, slipping into a coma. He died in 1986, never seeing the enacting of status aparte for Aruba for which he had worked over many years. After his death, Croes was proclaimed Libertador di Aruba. Croes' successor, Henny Eman, of the Aruban People's Party (AVP), became the first Prime Minister of Aruba. In 1985, Aruba's oil refinery had closed. It had provided Aruba with 30 percent of its real income and 50 percent of government revenue. The significant blow to the economy led to a push for a dramatic increase in tourism, and that sector has expanded to become the island's largest industry.

At a convention in The Hague in 1990, at the request of Aruba's Prime Minister Nelson Oduber, the governments of Aruba, the Netherlands, and the Netherlands Antilles postponed indefinitely Aruba's transition to full independence.

Geography Aruba is a generally flat, riverless island in the Leeward Antilles island arc of the Lesser Antilles in the southern part of the Caribbean. It lies west of Curaçao and north of Venezuela's Paraguaná Peninsula. Aruba has white sandy beaches on the western and southern coasts of the island, relatively sheltered from fierce ocean currents. This is where the bulk of the population live and where most tourist development has occurred. The northern and eastern coasts, lacking this protection, are considerably more battered by the sea and have been left largely untouched. The hinterland of the island features some rolling hills, such as Hooiberg at and Mount Jamanota, the highest on the island at above sea level. Oranjestad, the capital, is located at . The Natural Bridge was a large, naturally formed limestone bridge on the island's north shore. It was a popular tourist destination until its collapse in 2005. Cities and towns The island, with a population of about 116,600 people (1 January 2019 estimate) does not have major cities. It is divided into six districts. Most of the island's population resides in or around the two major city-like districts of Oranjestad (the capital) and San Nicolaas. Oranjestad and San Nicolaas are both divided into two districts for census purposes only. The districts are as follows: Noord Oranjestad (East and West) Paradera San Nicolaas (North and South) Santa Cruz Savaneta Fauna The isolation of Aruba from the mainland of South America has fostered the evolution of multiple endemic animals. The island provides a habitat for the endemic Aruban Whiptail and Aruba Rattlesnake, as well as an endemic subspecies of Burrowing Owl and Brown-throated Parakeet. Flora The flora of Aruba differs from the typical tropical island vegetation. Xeric scrublands are common, with various forms of cacti, thorny shrubs, and evergreens. Aloe vera is also present, its economic importance earning it a place on the coat of arms of Aruba. Cacti like Melocactus and Opuntia are represented on Aruba by species like Opuntia stricta. Trees like Caesalpinia coriaria and Vachellia tortuosa are drought tolerant. Climate and natural hazards By the Köppen climate classification, Aruba has a hot semi-arid climate (Köppen BSh). Rainfall is scarce, only 300 millimeters (12 inches) per year; in particular, rainy season is drier than it normally is in tropical climates; during the dry season, it almost never rains. Owing to the scarcity of rainfall, the landscape of Aruba is arid. Mean monthly temperature in Oranjestad varies little from to , moderated by constant trade winds from the Atlantic Ocean, which come from the north-east.

Yearly rainfall barely exceeds in Oranjestad, although it is extremely variable and can range from as little as during strong El Niño years (e.g. 1911/1912, 1930/1931, 1982/1983, 1997/1998) to over in La Niña years like 1933/1934, 1970/1971 or 1988/1989. Aruba is south of the typical latitudes of hurricanes but was affected by two in their early stages in late 2020. Demographics In terms of country of birth, the population is estimated to be 66% Aruban, 9.1% Colombian, 4.3% Dutch, 4.1% Dominican, 3.2% Venezuelan, 2.2% Curaçaoan, 1.5% Haitian, 1.2% Surinamese, 1.1% Peruvian, 1.1% Chinese, 6.2% other. In terms of ethnic composition, the population is estimated to be 75% mestizo, 15% black and 10% other ethnicities. Arawak heritage is stronger on Aruba than on most Caribbean islands; although no full-blooded Aboriginals remain, the features of the islanders clearly indicate their genetic Arawak heritage. Most of the population is descended from Caquetio Indians, African slaves, and Dutch settlers, and to a lesser extent the various other groups that have settled on the island over time, such as the Spanish, Portuguese, English, French, and Sephardic Jews. Recently, there has been substantial immigration to the island from neighbouring South American and Caribbean nations, attracted by the higher paid jobs. In 2007, new immigration laws were introduced to help control the growth of the population by restricting foreign workers to a maximum of three years residency on the island. Most notable are those from Venezuela, which lies just to the south. In 2019, recently arrived Venezuelan refugees were estimated to number around 17,000, accounting for some 15% of the island's population. Language Aruba's official languages are Dutch and Papiamento. While Dutch is the sole language for all administration and legal matters, Papiamento is the predominant language used on Aruba. Papiamento is a Portuguese- and Spanish-based creole language, spoken on Aruba, Bonaire, and Curaçao, that also incorporates words from Dutch and various West African languages. English and Spanish are also spoken, their usage having grown due to tourism. Other common languages spoken, based on the size of their community, are Portuguese, Cantonese, French and German. In recent years, the government of Aruba has shown an increased interest in acknowledging the cultural and historical importance of Papiamento. Although spoken Papiamento is fairly similar among the several Papiamento-speaking islands, there is a big difference in written Papiamento. The orthography differs per island, with Aruba using etymological spelling, and Curaçao and Bonaire a phonetic spelling. Some are more oriented towards Portuguese and use the equivalent spelling (e.g. "y" instead of "j"), where others are more oriented towards Dutch. The book Buccaneers of America, first published in 1678, states through eyewitness account that the natives on Aruba spoke Spanish already. Spanish became an important language in the 18th century due to the close economic ties with Spanish colonies in what are now Venezuela and Colombia. Venezuelan TV networks are received on the island, and Aruba also has significant Venezuelan and Colombian communities. Around 13% of the population today speaks Spanish natively.

In recent years, the government of Aruba has shown an increased interest in acknowledging the cultural and historical importance of Papiamento. Although spoken Papiamento is fairly similar among the several Papiamento-speaking islands, there is a big difference in written Papiamento. The orthography differs per island, with Aruba using etymological spelling, and Curaçao and Bonaire a phonetic spelling. Some are more oriented towards Portuguese and use the equivalent spelling (e.g. "y" instead of "j"), where others are more oriented towards Dutch. The book Buccaneers of America, first published in 1678, states through eyewitness account that the natives on Aruba spoke Spanish already. Spanish became an important language in the 18th century due to the close economic ties with Spanish colonies in what are now Venezuela and Colombia. Venezuelan TV networks are received on the island, and Aruba also has significant Venezuelan and Colombian communities. Around 13% of the population today speaks Spanish natively.

Yearly rainfall barely exceeds in Oranjestad, although it is extremely variable and can range from as little as during strong El Niño years (e.g. 1911/1912, 1930/1931, 1982/1983, 1997/1998) to over in La Niña years like 1933/1934, 1970/1971 or 1988/1989. Aruba is south of the typical latitudes of hurricanes but was affected by two in their early stages in late 2020. Demographics In terms of country of birth, the population is estimated to be 66% Aruban, 9.1% Colombian, 4.3% Dutch, 4.1% Dominican, 3.2% Venezuelan, 2.2% Curaçaoan, 1.5% Haitian, 1.2% Surinamese, 1.1% Peruvian, 1.1% Chinese, 6.2% other. In terms of ethnic composition, the population is estimated to be 75% mestizo, 15% black and 10% other ethnicities. Arawak heritage is stronger on Aruba than on most Caribbean islands; although no full-blooded Aboriginals remain, the features of the islanders clearly indicate their genetic Arawak heritage. Most of the population is descended from Caquetio Indians, African slaves, and Dutch settlers, and to a lesser extent the various other groups that have settled on the island over time, such as the Spanish, Portuguese, English, French, and Sephardic Jews. Recently, there has been substantial immigration to the island from neighbouring South American and Caribbean nations, attracted by the higher paid jobs. In 2007, new immigration laws were introduced to help control the growth of the population by restricting foreign workers to a maximum of three years residency on the island. Most notable are those from Venezuela, which lies just to the south. In 2019, recently arrived Venezuelan refugees were estimated to number around 17,000, accounting for some 15% of the island's population. Language Aruba's official languages are Dutch and Papiamento. While Dutch is the sole language for all administration and legal matters, Papiamento is the predominant language used on Aruba.

Use of English dates to the early 19th century, when the British took Curaçao, Aruba, and Bonaire. When Dutch rule resumed in 1815, officials already noted wide use of the language. Aruba has newspapers published in Papiamento: Diario, Bon Dia, Solo di Pueblo, and Awe Mainta, English: Aruba Daily, Aruba Today, and The News, and Dutch: Amigoe. Aruba has 18 radio stations (two AM and 16 FM) and two television stations (Telearuba and Channel 22). Religion Roman Catholicism is the dominant religion, practiced by about 75% of the population. Various Protestant denominations are also present on the island. Regions Aruba is cartographically split into eight for censuses; these regions have no administrative function; some allude to parishes which include a few charitable community facilities: Government Along with the Netherlands, Curaçao, and Sint Maarten, Aruba is a constituent country of the Kingdom of the Netherlands, with internal autonomy. Matters such as foreign affairs and defense are handled by the Netherlands. Aruba's politics take place within a framework of a 21-member Staten (Parliament) and an eight-member Cabinet; the Staten's 21 members are elected by direct, popular vote to serve a four-year term. The governor of Aruba is appointed for a six-year term by the monarch, and the prime minister and deputy prime minister are indirectly elected by the Staten for four-year terms. Aruba was formerly a part of the (now-defunct) Netherlands Antilles; however, it separated from that entity in 1986, gaining its own constitution. Aruba is designated as a member of the Overseas Countries and Territories (OCT) and is thus officially not a part of the European Union, though Aruba can and does receive support from the European Development Fund. Politics The Aruban legal system is based on the Dutch model. In Aruba, legal jurisdiction lies with the Gerecht in Eerste Aanleg (Court of First Instance) on Aruba, the Gemeenschappelijk Hof van Justitie van Aruba, Curaçao, Sint Maarten, en van Bonaire, Sint Eustatius en Saba (Joint Court of Justice of Aruba, Curaçao, Sint Maarten, and of Bonaire, Sint Eustatius and Saba) and the Hoge Raad der Nederlanden (Supreme Court of Justice of the Netherlands). The Korps Politie Aruba (Aruba Police Force) is the island's law enforcement agency and operates district precincts in Oranjestad, Noord, San Nicolaas, and Santa Cruz, where it is headquartered. Deficit spending has been a staple in Aruba's history, and modestly high inflation has been present as well. By 2006, the government's debt had grown to 1.883 billion Aruban florins.

The Dutch Armed Forces that protect the island include the Navy, Marine Corps, and the Coastguard including a platoon sized national guard. All forces are stationed at Marines base in Savaneta. Furthermore, in 1999, the U.S. Department of Defense established a Forward Operating Location (FOL) at the airport. Education Aruba's educational system is patterned after the Dutch system of education. The government of Aruba finances the public national education system. Schools are a mixture of public and private, including the International School of Aruba, the Schakel College and mostly the Colegio Arubano. There are three medical schools, American University School of Medicine Aruba (AUSOMA), Aureus University School of Medicine and Xavier University School of Medicine, as well as its own national university, the University of Aruba. Economy The island's economy is dominated by four main industries: tourism, aloe export, petroleum refining, and offshore banking. Aruba has one of the highest standards of living in the Caribbean region. The GDP per capita (PPP) for Aruba was estimated to be $37,500 in 2017. Its main trading partners are Colombia, the United States, Venezuela, and the Netherlands. The agriculture and manufacturing sectors are fairly minimal. Gold mining was important in the 19th century. Aloe was introduced to Aruba in 1840 but did not become a big export until 1890. Cornelius Eman founded Aruba Aloe Balm, and over time the industry became very important to the economy. At one point, two-thirds of the island was covered in Aloe Vera fields, and Aruba became the largest exporter of aloe in the world. The industry continues today, though on a smaller scale. Access to biocapacity in Aruba is much lower than world average. In 2016, Aruba had 0.57 global hectares of biocapacity per person within its territory, much less than the world average of 1.6 global hectares per person. In 2016, Aruba used 6.5 global hectares of biocapacity per person - their ecological footprint of consumption. This means they use almost 12 times the biocapacity that Aruba contains. This is the extent of Aruba's biocapacity deficit. The official exchange rate of the Aruban florin is pegged to the US dollar at 1.79 florins to US$1. This fact, and the majority of tourists being US, means businesses of hotel and resort districts prefer to bank and trade with the consumer in US dollars. Aruba is a prosperous country. Unemployment is low (although the government has not published statistics since 2013) and per capita income is one of the highest in the Caribbean (approximately $24,087). At the end of 2018, the labor force participation rate was 56.6% for women. Until the mid-1980s, Aruba's main industry was oil refining. Then the refinery was shut down and the island's economy shifted towards tourism. Currently, Aruba receives about 1,235,673 (2007) guests per year, of which three-quarters are Americans. Tourism is mainly focused on the beaches and the sea. The refinery has been closed and restarted repeatedly during the last decades.

In recent years a letter of intent was signed with CITGO (the US subsidiary of the Venezuelan state oil company PDVSA) to explore the possibility of reopening the refinery again. Until 2009, the Netherlands granted development aid to Aruba. This aid was mainly for law enforcement, education, administrative development, health care and sustainable economic development. This aid was discontinued at Aruba's request in 2009. Since 2015, however, a form of financial supervision has been reintroduced because Aruba's debt has risen sharply to over 80% of GDP. Aruba also has two free trade zones (Barcadera and Bushiri), where import and export and the movement of services are tax-free. Tourism Aruba has a large and well-developed tourism industry, receiving 1,082,000 tourists who stayed overnight in its territory in 2018. About of the Aruban gross national product is earned through tourism and related activities. Most tourists are from North America, with a market-share of 73.3%, followed by Latin America with 15.2% and Europe with 8.3%. In 2018, there were 40,231 visitors from the Netherlands. For private aircraft passengers bound for the United States, the United States Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) has a full pre-clearance facility since 1 February 2001 when Queen Beatrix Airport expanded. Since 2008, Aruba has been the only island to have this service for private flights. There are many luxury and lesser luxury hotels, concentrated mainly on the west coast beaches. In Palm Beach are the luxury hotels aimed at American tourists. This area is also called "Highrise-area", because most of the hotels are located in (by Aruban standards) high-rise buildings. Eagle Beach, a short distance from Palm Beach in the direction of Oranjestad, offers hotels on a somewhat smaller and more intimate scale in low-rise buildings, hence the name "lowrise-area". Oranjestad is the port for the many cruise ships that visit Aruba. The cruise industry is a very important pillar of tourism in Aruba, since during a cruise a large part of the passengers go ashore to visit the island. With 334 cruise calls, Aruba received 815,161 cruise tourists in 2018. The 2017/2018 cruise season brought $102.8 million to Aruba's economy. Oranjestad is also home to several luxury hotels, upscale shopping malls, tourist-oriented shopping streets, and hospitality facilities. The main street, called Caya G.F. (Betico) Croes, has been redesigned in recent years, including new paving, new palm trees and a streetcar line for tourists. Culture Aruba has a varied culture. According to the Bureau Burgelijke Stand en Bevolkingsregister (BBSB), in 2005 there were ninety-two different nationalities living on the island. Dutch influence can still be seen, as in the celebration of "Sinterklaas" on 5 and 6 December and other national holidays like 27 April, when in Aruba and the rest of the Kingdom of the Netherlands the King's birthday or "Dia di Rey" (Koningsdag) is celebrated. On 18 March, Aruba celebrates its National Day.

On 18 March, Aruba celebrates its National Day.

Christmas and New Year's Eve are celebrated with the typical music and songs for gaitas for Christmas and the Dande for New Year, and ayaca, ponche crema, ham, and other typical foods and drinks. On 25 January, Betico Croes' birthday is celebrated. Dia di San Juan is celebrated on 24 June. Besides Christmas, the religious holy days of the Feast of the Ascension and Good Friday are also holidays on the island. The festival of Carnaval is also an important one in Aruba, as it is in many Caribbean and Latin American countries. Its celebration in Aruba started in the 1950s, influenced by the inhabitants from Venezuela and the nearby islands (Curaçao, St. Vincent, Trinidad, Barbados, St. Maarten, and Anguilla) who came to work for the oil refinery. Over the years, the Carnival Celebration has changed and now starts from the beginning of January until the Tuesday before Ash Wednesday, with a large parade on the last Sunday of the festivities (the Sunday before Ash Wednesday). Tourism from the United States has recently increased the visibility of American culture on the island, with such celebrations as Halloween in October and Thanksgiving Day in November. Architecture From the beginning of the colonization of the Netherlands until the beginning of the 20th century, the architecture in the most inhabited areas of Aruba was influenced by the Dutch colonial style and also some Spanish elements from the Catholic missionaries present in Aruba who later settled in Venezuela as well. After the boom of the oil industry and the tourist sector in the 20th century the architectural style of the island incorporated a more American and international influence. In addition, elements of the Art Deco style can still be seen in several buildings in San Nicolas. Therefore, it can be said that the island's architecture is a mixture of Spanish, Dutch, American and Caribbean influences. Infrastructure Aruba's Queen Beatrix International Airport is near Oranjestad. Aruba has four ports: Barcadera, the main cargo port, Paardenbaai, the cruise ship terminal in Oranjestad/Taratata, Commandeurs Baai (Commander's Bay) in Savaneta, and Sint Nicolaas Baai in San Nicolaas. Paardenbaai services all the cruise-ship lines such as Royal Caribbean, Carnival, NCL, Holland America, MSC Cruises, Costa Cruises, P&O Cruises and Disney. Nearly one million tourists enter this port per year. Aruba Ports Authority, owned and operated by the Aruban government, runs these seaports. Arubus is a government-owned bus company. Its buses operate from 3:30 a.m. until 12:30 a.m., 365 days a year. Private minibuses/people movers service zones such as the Hotel Area, San Nicolaas, Santa Cruz and Noord. A streetcar service runs on rails on the Mainstreet of Oranjestad. Utilities Water- en Energiebedrijf Aruba, N.V. (W.E.B.) produces potable water and power; its eponymous plant was one of the world's largest desalination plants as of 2007. Average daily consumption in Aruba is about . N.V. Elmar is the sole distributor of electricity on the island of Aruba.

Christmas and New Year's Eve are celebrated with the typical music and songs for gaitas for Christmas and the Dande for New Year, and ayaca, ponche crema, ham, and other typical foods and drinks. On 25 January, Betico Croes' birthday is celebrated. Dia di San Juan is celebrated on 24 June. Besides Christmas, the religious holy days of the Feast of the Ascension and Good Friday are also holidays on the island. The festival of Carnaval is also an important one in Aruba, as it is in many Caribbean and Latin American countries. Its celebration in Aruba started in the 1950s, influenced by the inhabitants from Venezuela and the nearby islands (Curaçao, St. Vincent, Trinidad, Barbados, St. Maarten, and Anguilla) who came to work for the oil refinery. Over the years, the Carnival Celebration has changed and now starts from the beginning of January until the Tuesday before Ash Wednesday, with a large parade on the last Sunday of the festivities (the Sunday before Ash Wednesday). Tourism from the United States has recently increased the visibility of American culture on the island, with such celebrations as Halloween in October and Thanksgiving Day in November. Architecture From the beginning of the colonization of the Netherlands until the beginning of the 20th century, the architecture in the most inhabited areas of Aruba was influenced by the Dutch colonial style and also some Spanish elements from the Catholic missionaries present in Aruba who later settled in Venezuela as well. After the boom of the oil industry and the tourist sector in the 20th century the architectural style of the island incorporated a more American and international influence. In addition, elements of the Art Deco style can still be seen in several buildings in San Nicolas. Therefore, it can be said that the island's architecture is a mixture of Spanish, Dutch, American and Caribbean influences.

Articles of Confederation The Articles of Confederation and Perpetual Union was an agreement among the 13 original states of the United States of America that served as its first frame of government. It was approved after much debate (between July 1776 and November 1777) by the Second Continental Congress on November 15, 1777, and sent to the states for ratification. The Articles of Confederation came into force on March 1, 1781, after ratification by all the states. A guiding principle of the Articles was to preserve the independence and sovereignty of the states. The weak central government established by the Articles received only those powers which the former colonies had recognized as belonging to king and parliament. The document provided clearly written rules for how the states' "league of friendship" would be organized. During the ratification process, the Congress looked to the Articles for guidance as it conducted business, directing the war effort, conducting diplomacy with foreign states, addressing territorial issues and dealing with Native American relations. Little changed politically once the Articles of Confederation went into effect, as ratification did little more than legalize what the Continental Congress had been doing. That body was renamed the Congress of the Confederation; but most Americans continued to call it the Continental Congress, since its organization remained the same. As the Confederation Congress attempted to govern the continually growing American states, delegates discovered that the limitations placed upon the central government rendered it ineffective at doing so. As the government's weaknesses became apparent, especially after Shays' Rebellion, some prominent political thinkers in the fledgling union began asking for changes to the Articles. Their hope was to create a stronger government. Initially, some states met to deal with their trade and economic problems. However, as more states became interested in meeting to change the Articles, a meeting was set in Philadelphia on May 25, 1787. This became the Constitutional Convention. It was quickly agreed that changes would not work, and instead the entire Articles needed to be replaced. On March 4, 1789, the government under the Articles was replaced with the federal government under the Constitution. The new Constitution provided for a much stronger federal government by establishing a chief executive (the President), courts, and taxing powers. The Articles of Confederation is considered one of the United States' four major founding documents, along with the Continental Association, the Declaration of Independence, and the Constitution. Background and context The political push to increase cooperation among the then-loyal colonies began with the Albany Congress in 1754 and Benjamin Franklin's proposed Albany Plan, an inter-colonial collaboration to help solve mutual local problems. Over the next two decades, some of the basic concepts it addressed would strengthen; others would weaken, especially in the degree of loyalty (or lack thereof) owed the Crown.

Civil disobedience resulted in coercive and quelling measures, such as the passage of what the colonials referred to as the Intolerable Acts in the British Parliament, and armed skirmishes which resulted in dissidents being proclaimed rebels. These actions eroded the number of Crown Loyalists (Tories) among the colonials and, together with the highly effective propaganda campaign of the Patriot leaders, caused an increasing number of colonists to begin agitating for independence from the mother country. In 1775, with events outpacing communications, the Second Continental Congress began acting as the provisional government. It was an era of constitution writing—most states were busy at the task—and leaders felt the new nation must have a written constitution; a "rulebook" for how the new nation should function. During the war, Congress exercised an unprecedented level of political, diplomatic, military and economic authority. It adopted trade restrictions, established and maintained an army, issued fiat money, created a military code and negotiated with foreign governments. To transform themselves from outlaws into a legitimate nation, the colonists needed international recognition for their cause and foreign allies to support it. In early 1776, Thomas Paine argued in the closing pages of the first edition of Common Sense that the "custom of nations" demanded a formal declaration of American independence if any European power were to mediate a peace between the Americans and Great Britain. The monarchies of France and Spain, in particular, could not be expected to aid those they considered rebels against another legitimate monarch. Foreign courts needed to have American grievances laid before them persuasively in a "manifesto" which could also reassure them that the Americans would be reliable trading partners. Without such a declaration, Paine concluded, "[t]he custom of all courts is against us, and will be so, until, by an independence, we take rank with other nations." Beyond improving their existing association, the records of the Second Continental Congress show that the need for a declaration of independence was intimately linked with the demands of international relations. On June 7, 1776, Richard Henry Lee introduced a resolution before the Continental Congress declaring the colonies independent; at the same time, he also urged Congress to resolve "to take the most effectual measures for forming foreign Alliances" and to prepare a plan of confederation for the newly independent states. Congress then created three overlapping committees to draft the Declaration, a model treaty, and the Articles of Confederation. The Declaration announced the states' entry into the international system; the model treaty was designed to establish amity and commerce with other states; and the Articles of Confederation, which established "a firm league" among the thirteen free and independent states, constituted an international agreement to set up central institutions for the conduct of vital domestic and foreign affairs.

Drafting On June 12, 1776, a day after appointing a committee to prepare a draft of the Declaration of Independence, the Second Continental Congress resolved to appoint a committee of 13 with one representative from each colony to prepare a draft of a constitution for a union of the states. The committee was made up of the following individuals: John Dickinson (Pennsylvania, chairman of the committee) Samuel Adams (Massachusetts) Josiah Bartlett (New Hampshire) Button Gwinnett (Georgia) Joseph Hewes (North Carolina) Stephen Hopkins (Rhode Island) Robert R. Livingston (New York) Thomas McKean (Delaware) Thomas Nelson (Virginia) Edward Rutledge (South Carolina) Roger Sherman (Connecticut) Thomas Stone (Maryland) Francis Hopkinson (New Jersey, added to the committee last) The committee met frequently, and chairman John Dickinson presented their results to the Congress on July 12, 1776. Afterward, there were long debates on such issues as state sovereignty, the exact powers to be given to Congress, whether to have a judiciary, western land claims, and voting procedures. To further complicate work on the constitution, Congress was forced to leave Philadelphia twice, for Baltimore, Maryland, in the winter of 1776, and later for Lancaster then York, Pennsylvania, in the fall of 1777, to evade advancing British troops. Even so, the committee continued with its work. The final draft of the Articles of Confederation and Perpetual Union was completed on November 15, 1777. Consensus was achieved by: including language guaranteeing that each state retained its sovereignty, leaving the matter of western land claims in the hands of the individual states, including language stating that votes in Congress would be en bloc by state, and establishing a unicameral legislature with limited and clearly delineated powers. Ratification The Articles of Confederation was submitted to the states for ratification in late November 1777. The first state to ratify was Virginia on December 16, 1777; 12 states had ratified the Articles by February 1779, 14 months into the process. The lone holdout, Maryland, refused to go along until the landed states, especially Virginia, had indicated they were prepared to cede their claims west of the Ohio River to the Union. It would be two years before the Maryland General Assembly became satisfied that the various states would follow through, and voted to ratify. During this time, Congress observed the Articles as its de facto frame of government. Maryland finally ratified the Articles on February 2, 1781. Congress was informed of Maryland's assent on March 1, and officially proclaimed the Articles of Confederation to be the law of the land. The several states ratified the Articles of Confederation on the following dates: Article summaries The Articles of Confederation contain a preamble, thirteen articles, a conclusion, and a signatory section. The individual articles set the rules for current and future operations of the confederation's central government.

Consensus was achieved by: including language guaranteeing that each state retained its sovereignty, leaving the matter of western land claims in the hands of the individual states, including language stating that votes in Congress would be en bloc by state, and establishing a unicameral legislature with limited and clearly delineated powers. Ratification The Articles of Confederation was submitted to the states for ratification in late November 1777. The first state to ratify was Virginia on December 16, 1777; 12 states had ratified the Articles by February 1779, 14 months into the process. The lone holdout, Maryland, refused to go along until the landed states, especially Virginia, had indicated they were prepared to cede their claims west of the Ohio River to the Union. It would be two years before the Maryland General Assembly became satisfied that the various states would follow through, and voted to ratify. During this time, Congress observed the Articles as its de facto frame of government. Maryland finally ratified the Articles on February 2, 1781. Congress was informed of Maryland's assent on March 1, and officially proclaimed the Articles of Confederation to be the law of the land. The several states ratified the Articles of Confederation on the following dates: Article summaries The Articles of Confederation contain a preamble, thirteen articles, a conclusion, and a signatory section. The individual articles set the rules for current and future operations of the confederation's central government.

Drafting On June 12, 1776, a day after appointing a committee to prepare a draft of the Declaration of Independence, the Second Continental Congress resolved to appoint a committee of 13 with one representative from each colony to prepare a draft of a constitution for a union of the states. The committee was made up of the following individuals: John Dickinson (Pennsylvania, chairman of the committee) Samuel Adams (Massachusetts) Josiah Bartlett (New Hampshire) Button Gwinnett (Georgia) Joseph Hewes (North Carolina) Stephen Hopkins (Rhode Island) Robert R. Livingston (New York) Thomas McKean (Delaware) Thomas Nelson (Virginia) Edward Rutledge (South Carolina) Roger Sherman (Connecticut) Thomas Stone (Maryland) Francis Hopkinson (New Jersey, added to the committee last) The committee met frequently, and chairman John Dickinson presented their results to the Congress on July 12, 1776. Afterward, there were long debates on such issues as state sovereignty, the exact powers to be given to Congress, whether to have a judiciary, western land claims, and voting procedures.

The several states ratified the Articles of Confederation on the following dates: Article summaries The Articles of Confederation contain a preamble, thirteen articles, a conclusion, and a signatory section. The individual articles set the rules for current and future operations of the confederation's central government.

Under the Articles, the states retained sovereignty over all governmental functions not specifically relinquished to the national Congress, which was empowered to make war and peace, negotiate diplomatic and commercial agreements with foreign countries, and to resolve disputes between the states. The document also stipulates that its provisions "shall be inviolably observed by every state" and that "the Union shall be perpetual". Summary of the purpose and content of each of the 13 articles: Establishes the name of the confederation with these words: "The stile of this confederacy shall be 'The United States of America.'" Asserts the sovereignty of each state, except for the specific powers delegated to the confederation government: "Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated." Declares the purpose of the confederation: "The said States hereby severally enter into a firm league of friendship with each other, for their common defense, the security of their liberties, and their mutual and general welfare, binding themselves to assist each other, against all force offered to, or attacks made upon them, or any of them, on account of religion, sovereignty, trade, or any other pretense whatever." Elaborates upon the intent "to secure and perpetuate mutual friendship and intercourse among the people of the different States in this union," and to establish equal treatment and freedom of movement for the free inhabitants of each state to pass unhindered between the states, excluding "paupers, vagabonds, and fugitives from justice." All these people are entitled to equal rights established by the state into which they travel. If a crime is committed in one state and the perpetrator flees to another state, he will be extradited to and tried in the state in which the crime was committed. Allocates one vote in the Congress of the Confederation (the "United States in Congress Assembled") to each state, which is entitled to a delegation of between two and seven members. Members of Congress are to be appointed by state legislatures. No congressman may serve more than three out of any six years. Only the central government may declare war, or conduct foreign political or commercial relations. No state or official may accept foreign gifts or titles, and granting any title of nobility is forbidden to all. No states may form any sub-national groups. No state may tax or interfere with treaty stipulations already proposed. No state may wage war without permission of Congress, unless invaded or under imminent attack on the frontier; no state may maintain a peacetime standing army or navy, unless infested by pirates, but every State is required to keep ready, a well-trained, disciplined, and equipped militia. Whenever an army is raised for common defense, the state legislatures shall assign military ranks of colonel and below. Expenditures by the United States of America will be paid with funds raised by state legislatures, and apportioned to the states in proportion to the real property values of each.

Powers and functions of the United States in Congress Assembled. Grants to the United States in Congress assembled the sole and exclusive right and power to determine peace and war; to exchange ambassadors; to enter into treaties and alliances, with some provisos; to establish rules for deciding all cases of captures or prizes on land or water; to grant letters of marque and reprisal (documents authorizing privateers) in times of peace; to appoint courts for the trial of pirates and crimes committed on the high seas; to establish courts for appeals in all cases of captures, but no member of Congress may be appointed a judge; to set weights and measures (including coins), and for Congress to serve as a final court for disputes between states. The court will be composed of jointly appointed commissioners or Congress shall appoint them. Each commissioner is bound by oath to be impartial. The court's decision is final. Congress shall regulate the post offices; appoint officers in the military; and regulate the armed forces. The United States in Congress assembled may appoint a president who shall not serve longer than one year per three-year term of the Congress. Congress may request requisitions (demands for payments or supplies) from the states in proportion with their population, or take credit. Congress may not declare war, enter into treaties and alliances, appropriate money, or appoint a commander in chief without nine states assenting. Congress shall keep a journal of proceedings and adjourn for periods not to exceed six months. When Congress is in recess, any of the powers of Congress may be executed by "The committee of the states, or any nine of them", except for those powers of Congress which require nine states in Congress to execute. If Canada [referring to the British Province of Quebec] accedes to this confederation, it will be admitted. No other colony could be admitted without the consent of nine states. Affirms that the Confederation will honor all bills of credit incurred, monies borrowed, and debts contracted by Congress before the existence of the Articles. Declares that the Articles shall be perpetual, and may be altered only with the approval of Congress and the ratification of all the state legislatures. Congress under the Articles Army Under the Articles, Congress had the authority to regulate and fund the Continental Army, but it lacked the power to compel the States to comply with requests for either troops or funding. This left the military vulnerable to inadequate funding, supplies, and even food. Further, although the Articles enabled the states to present a unified front when dealing with the European powers, as a tool to build a centralized war-making government, they were largely a failure; Historian Bruce Chadwick wrote: Phelps wrote: The Continental Congress, before the Articles were approved, had promised soldiers a pension of half pay for life.

However Congress had no power to compel the states to fund this obligation, and as the war wound down after the victory at Yorktown the sense of urgency to support the military was no longer a factor. No progress was made in Congress during the winter of 1783–84. General Henry Knox, who would later become the first Secretary of War under the Constitution, blamed the weaknesses of the Articles for the inability of the government to fund the army. The army had long been supportive of a strong union. Knox wrote: As Congress failed to act on the petitions, Knox wrote to Gouverneur Morris, four years before the Philadelphia Convention was convened, "As the present Constitution is so defective, why do not you great men call the people together and tell them so; that is, to have a convention of the States to form a better Constitution." Once the war had been won, the Continental Army was largely disbanded. A very small national force was maintained to man the frontier forts and to protect against Native American attacks. Meanwhile, each of the states had an army (or militia), and 11 of them had navies. The wartime promises of bounties and land grants to be paid for service were not being met. In 1783, George Washington defused the Newburgh conspiracy, but riots by unpaid Pennsylvania veterans forced Congress to leave Philadelphia temporarily. The Congress from time to time during the Revolutionary War requisitioned troops from the states. Any contributions were voluntary, and in the debates of 1788, the Federalists (who supported the proposed new Constitution) claimed that state politicians acted unilaterally, and contributed when the Continental army protected their state's interests. The Anti-Federalists claimed that state politicians understood their duty to the Union and contributed to advance its needs. Dougherty (2009) concludes that generally the States' behavior validated the Federalist analysis. This helps explain why the Articles of Confederation needed reforms. Foreign policy The 1783 Treaty of Paris, which ended hostilities with Great Britain, languished in Congress for several months because too few delegates were present at any one time to constitute a quorum so that it could be ratified. Afterward, the problem only got worse as Congress had no power to enforce attendance. Rarely did more than half of the roughly sixty delegates attend a session of Congress at the time, causing difficulties in raising a quorum. The resulting paralysis embarrassed and frustrated many American nationalists, including George Washington. Many of the most prominent national leaders, such as Washington, John Adams, John Hancock, and Benjamin Franklin, retired from public life, served as foreign delegates, or held office in state governments; and for the general public, local government and self-rule seemed quite satisfactory. This served to exacerbate Congress's impotence. Inherent weaknesses in the confederation's frame of government also frustrated the ability of the government to conduct foreign policy.

In 1786, Thomas Jefferson, concerned over the failure of Congress to fund an American naval force to confront the Barbary pirates, wrote in a diplomatic correspondence to James Monroe that, "It will be said there is no money in the treasury. There never will be money in the treasury till the Confederacy shows its teeth." Furthermore, the 1786 Jay–Gardoqui Treaty with Spain also showed weakness in foreign policy. In this treaty, which was never ratified, the United States was to give up rights to use the Mississippi River for 25 years, which would have economically strangled the settlers west of the Appalachian Mountains. Finally, due to the Confederation's military weakness, it could not compel the British army to leave frontier forts which were on American soil — forts which, in 1783, the British promised to leave, but which they delayed leaving pending U.S. implementation of other provisions such as ending action against Loyalists and allowing them to seek compensation. This incomplete British implementation of the Treaty of Paris would later be resolved by the implementation of Jay's Treaty in 1795 after the federal Constitution came into force. Taxation and commerce Under the Articles of Confederation, the central government's power was kept quite limited. The Confederation Congress could make decisions but lacked enforcement powers. Implementation of most decisions, including modifications to the Articles, required unanimous approval of all thirteen state legislatures. Congress was denied any powers of taxation: it could only request money from the states. The states often failed to meet these requests in full, leaving both Congress and the Continental Army chronically short of money. As more money was printed by Congress, the continental dollars depreciated. In 1779, George Washington wrote to John Jay, who was serving as the president of the Continental Congress, "that a wagon load of money will scarcely purchase a wagon load of provisions." Mr. Jay and the Congress responded in May by requesting $45 million from the States. In an appeal to the States to comply, Jay wrote that the taxes were "the price of liberty, the peace, and the safety of yourselves and posterity." He argued that Americans should avoid having it said "that America had no sooner become independent than she became insolvent" or that "her infant glories and growing fame were obscured and tarnished by broken contracts and violated faith." The States did not respond with any of the money requested from them. Congress had also been denied the power to regulate either foreign trade or interstate commerce and, as a result, all of the States maintained control over their own trade policies. The states and the Confederation Congress both incurred large debts during the Revolutionary War, and how to repay those debts became a major issue of debate following the War. Some States paid off their war debts and others did not. Federal assumption of the states' war debts became a major issue in the deliberations of the Constitutional Convention.

In 1779, George Washington wrote to John Jay, who was serving as the president of the Continental Congress, "that a wagon load of money will scarcely purchase a wagon load of provisions." Mr. Jay and the Congress responded in May by requesting $45 million from the States. In an appeal to the States to comply, Jay wrote that the taxes were "the price of liberty, the peace, and the safety of yourselves and posterity." He argued that Americans should avoid having it said "that America had no sooner become independent than she became insolvent" or that "her infant glories and growing fame were obscured and tarnished by broken contracts and violated faith." The States did not respond with any of the money requested from them. Congress had also been denied the power to regulate either foreign trade or interstate commerce and, as a result, all of the States maintained control over their own trade policies. The states and the Confederation Congress both incurred large debts during the Revolutionary War, and how to repay those debts became a major issue of debate following the War. Some States paid off their war debts and others did not. Federal assumption of the states' war debts became a major issue in the deliberations of the Constitutional Convention.

Accomplishments Nevertheless, the Confederation Congress did take two actions with long-lasting impact. The Land Ordinance of 1785 and Northwest Ordinance created territorial government, set up protocols for the admission of new states and the division of land into useful units, and set aside land in each township for public use. This system represented a sharp break from imperial colonization, as in Europe, and it established the precedent by which the national (later, federal) government would be sovereign and expand westward—as opposed to the existing states doing so under their sovereignty. The Land Ordinance of 1785 established both the general practices of land surveying in the west and northwest and the land ownership provisions used throughout the later westward expansion beyond the Mississippi River. Frontier lands were surveyed into the now-familiar squares of land called the township (36 square miles), the section (one square mile), and the quarter section (160 acres). This system was carried forward to most of the States west of the Mississippi (excluding areas of Texas and California that had already been surveyed and divided up by the Spanish Empire). Then, when the Homestead Act was enacted in 1867, the quarter section became the basic unit of land that was granted to new settler-farmers. The Northwest Ordinance of 1787 noted the agreement of the original states to give up northwestern land claims, organized the Northwest Territory and laid the groundwork for the eventual creation of new states. While it didn't happen under the articles, the land north of the Ohio River and west of the (present) western border of Pennsylvania ceded by Massachusetts, Connecticut, New York, Pennsylvania, and Virginia, eventually became the states of: Ohio, Indiana, Illinois, Michigan, and Wisconsin, and the part of Minnesota east of the Mississippi River. The Northwest Ordinance of 1787 also made great advances in the abolition of slavery. New states admitted to the union in this territory would never be slave states. No new states were admitted to the Union under the Articles of Confederation. The Articles provided for a blanket acceptance of the Province of Quebec (referred to as "Canada" in the Articles) into the United States if it chose to do so. It did not, and the subsequent Constitution carried no such special provision of admission. Additionally, ordinances to admit Frankland (later modified to Franklin), Kentucky, and Vermont to the Union were considered, but none were approved. Presidents of Congress Under the Articles of Confederation, the presiding officer of Congress—referred to in many official records as President of the United States in Congress Assembled—chaired the Committee of the States when Congress was in recess, and performed other administrative functions. He was not, however, an executive in the way the later President of the United States is a chief executive, since all of the functions he executed were under the direct control of Congress. There were 10 presidents of Congress under the Articles. The first, Samuel Huntington, had been serving as president of the Continental Congress since September 28, 1779.

U.S. under the Articles The peace treaty left the United States independent and at peace but with an unsettled governmental structure. The Articles envisioned a permanent confederation but granted to the Congress—the only federal institution—little power to finance itself or to ensure that its resolutions were enforced. There was no president, no executive agencies, no judiciary, and no tax base. The absence of a tax base meant that there was no way to pay off state and national debts from the war years except by requesting money from the states, which seldom arrived. Although historians generally agree that the Articles were too weak to hold the fast-growing nation together, they do give credit to the settlement of the western issue, as the states voluntarily turned over their lands to national control. By 1783, with the end of the British blockade, the new nation was regaining its prosperity. However, trade opportunities were restricted by the mercantilism of the British and French empires. The ports of the British West Indies were closed to all staple products which were not carried in British ships. France and Spain established similar policies. Simultaneously, new manufacturers faced sharp competition from British products which were suddenly available again. Political unrest in several states and efforts by debtors to use popular government to erase their debts increased the anxiety of the political and economic elites which had led the Revolution. The apparent inability of the Congress to redeem the public obligations (debts) incurred during the war, or to become a forum for productive cooperation among the states to encourage commerce and economic development, only aggravated a gloomy situation. In 1786–87, Shays' Rebellion, an uprising of dissidents in western Massachusetts against the state court system, threatened the stability of state government. The Continental Congress printed paper money which was so depreciated that it ceased to pass as currency, spawning the expression "not worth a continental". Congress could not levy taxes and could only make requisitions upon the States. Less than a million and a half dollars came into the treasury between 1781 and 1784, although the governors had been asked for two million in 1783 alone. When John Adams went to London in 1785 as the first representative of the United States, he found it impossible to secure a treaty for unrestricted commerce. Demands were made for favors and there was no assurance that individual states would agree to a treaty. Adams stated it was necessary for the States to confer the power of passing navigation laws to Congress, or that the States themselves pass retaliatory acts against Great Britain. Congress had already requested and failed to get power over navigation laws. Meanwhile, each State acted individually against Great Britain to little effect. When other New England states closed their ports to British shipping, Connecticut hastened to profit by opening its ports. By 1787 Congress was unable to protect manufacturing and shipping. State legislatures were unable or unwilling to resist attacks upon private contracts and public credit.

Land speculators expected no rise in values when the government could not defend its borders nor protect its frontier population. The idea of a convention to revise the Articles of Confederation grew in favor. Alexander Hamilton realized while serving as Washington's top aide that a strong central government was necessary to avoid foreign intervention and allay the frustrations due to an ineffectual Congress. Hamilton led a group of like-minded nationalists, won Washington's endorsement, and convened the Annapolis Convention in 1786 to petition Congress to call a constitutional convention to meet in Philadelphia to remedy the long-term crisis. Signatures The Second Continental Congress approved the Articles for distribution to the states on November 15, 1777. A copy was made for each state and one was kept by the Congress. On November 28, the copies sent to the states for ratification were unsigned, and the cover letter, dated November 17, had only the signatures of Henry Laurens and Charles Thomson, who were the President and Secretary to the Congress. The Articles, however, were unsigned, and the date was blank. Congress began the signing process by examining their copy of the Articles on June 27, 1778. They ordered a final copy prepared (the one in the National Archives), and that delegates should inform the secretary of their authority for ratification. On July 9, 1778, the prepared copy was ready. They dated it and began to sign. They also requested each of the remaining states to notify its delegation when ratification was completed. On that date, delegates present from New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, Pennsylvania, Virginia and South Carolina signed the Articles to indicate that their states had ratified. New Jersey, Delaware and Maryland could not, since their states had not ratified. North Carolina and Georgia also were unable to sign that day, since their delegations were absent. After the first signing, some delegates signed at the next meeting they attended. For example, John Wentworth of New Hampshire added his name on August 8. John Penn was the first of North Carolina's delegates to arrive (on July 10), and the delegation signed the Articles on July 21, 1778. The other states had to wait until they ratified the Articles and notified their Congressional delegation. Georgia signed on July 24, New Jersey on November 26, and Delaware on February 12, 1779. Maryland refused to ratify the Articles until every state had ceded its western land claims. Chevalier de La Luzerne, French Minister to the United States, felt that the Articles would help strengthen the American government. In 1780, when Maryland requested France provide naval forces in the Chesapeake Bay for protection from the British (who were conducting raids in the lower part of the bay), he indicated that French Admiral Destouches would do what he could but La Luzerne also "sharply pressed" Maryland to ratify the Articles, thus suggesting the two issues were related. On February 2, 1781, the much-awaited decision was taken by the Maryland General Assembly in Annapolis.

As the last piece of business during the afternoon Session, "among engrossed Bills" was "signed and sealed by Governor Thomas Sim Lee in the Senate Chamber, in the presence of the members of both Houses... an Act to empower the delegates of this state in Congress to subscribe and ratify the articles of confederation" and perpetual union among the states. The Senate then adjourned "to the first Monday in August next." The decision of Maryland to ratify the Articles was reported to the Continental Congress on February 12. The confirmation signing of the Articles by the two Maryland delegates took place in Philadelphia at noon time on March 1, 1781, and was celebrated in the afternoon. With these events, the Articles were entered into force and the United States of America came into being as a sovereign federal state. Congress had debated the Articles for over a year and a half, and the ratification process had taken nearly three and a half years.

At its conclusion, delegates voted to invite all states to a larger convention to be held in Philadelphia in 1787. The Confederation Congress later endorsed this convention "for the sole and express purpose of revising the Articles of Confederation". Although the states' representatives to the Constitutional Convention in Philadelphia were only authorized to amend the Articles, delegates held secret, closed-door sessions and wrote a new constitution. The new frame of government gave much more power to the central government, but characterization of the result is disputed. The general goal of the authors was to get close to a republic as defined by the philosophers of the Age of Enlightenment, while trying to address the many difficulties of the interstate relationships. Historian Forrest McDonald, using the ideas of James Madison from Federalist 39, described the change this way: In May 1786, Charles Pinckney of South Carolina proposed that Congress revise the Articles of Confederation. Recommended changes included granting Congress power over foreign and domestic commerce, and providing means for Congress to collect money from state treasuries. Unanimous approval was necessary to make the alterations, however, and Congress failed to reach a consensus. The weakness of the Articles in establishing an effective unifying government was underscored by the threat of internal conflict both within and between the states, especially after Shays' Rebellion threatened to topple the state government of Massachusetts. Historian Ralph Ketcham commented on the opinions of Patrick Henry, George Mason, and other Anti-Federalists who were not so eager to give up the local autonomy won by the revolution: Historians have given many reasons for the perceived need to replace the articles in 1787. Jillson and Wilson (1994) point to the financial weakness as well as the norms, rules and institutional structures of the Congress, and the propensity to divide along sectional lines. Rakove identifies several factors that explain the collapse of the Confederation. The lack of compulsory direct taxation power was objectionable to those wanting a strong centralized state or expecting to benefit from such power. It could not collect customs after the war because tariffs were vetoed by Rhode Island. Rakove concludes that their failure to implement national measures "stemmed not from a heady sense of independence but rather from the enormous difficulties that all the states encountered in collecting taxes, mustering men, and gathering supplies from a war-weary populace." The second group of factors Rakove identified derived from the substantive nature of the problems the Continental Congress confronted after 1783, especially the inability to create a strong foreign policy. Finally, the Confederation's lack of coercive power reduced the likelihood for profit to be made by political means, thus potential rulers were uninspired to seek power. When the war ended in 1783, certain special interests had incentives to create a new "merchant state," much like the British state people had rebelled against.

At its conclusion, delegates voted to invite all states to a larger convention to be held in Philadelphia in 1787. The Confederation Congress later endorsed this convention "for the sole and express purpose of revising the Articles of Confederation". Although the states' representatives to the Constitutional Convention in Philadelphia were only authorized to amend the Articles, delegates held secret, closed-door sessions and wrote a new constitution.

In particular, holders of war scrip and land speculators wanted a central government to pay off scrip at face value and to legalize western land holdings with disputed claims. Also, manufacturers wanted a high tariff as a barrier to foreign goods, but competition among states made this impossible without a central government. Legitimacy of closing down Two prominent political leaders in the Confederation, John Jay of New York and Thomas Burke of North Carolina believed that "the authority of the congress rested on the prior acts of the several states, to which the states gave their voluntary consent, and until those obligations were fulfilled, neither nullification of the authority of congress, exercising its due powers, nor secession from the compact itself was consistent with the terms of their original pledges." According to Article XIII of the Confederation, any alteration had to be approved unanimously: [T]he Articles of this Confederation shall be inviolably observed by every State, and the Union shall be perpetual; nor shall any alteration at any time hereafter be made in any of them; unless such alteration be agreed to in a Congress of the United States, and be afterwards confirmed by the legislatures of every State. On the other hand, Article VII of the proposed Constitution stated that it would become effective after ratification by a mere nine states, without unanimity: The Ratification of the Conventions of nine States, shall be sufficient for the Establishment of this Constitution between the States so ratifying the Same. The apparent tension between these two provisions was addressed at the time, and remains a topic of scholarly discussion. In 1788, James Madison remarked (in Federalist No. 40) that the issue had become moot: "As this objection… has been in a manner waived by those who have criticised the powers of the convention, I dismiss it without further observation." Nevertheless, it is a historical and legal question whether opponents of the Constitution could have plausibly attacked the Constitution on that ground. At the time, there were state legislators who argued that the Constitution was not an alteration of the Articles of Confederation, but rather would be a complete replacement so the unanimity rule did not apply. Moreover, the Confederation had proven woefully inadequate and therefore was supposedly no longer binding. Modern scholars such as Francisco Forrest Martin agree that the Articles of Confederation had lost its binding force because many states had violated it, and thus "other states-parties did not have to comply with the Articles' unanimous consent rule". In contrast, law professor Akhil Amar suggests that there may not have really been any conflict between the Articles of Confederation and the Constitution on this point; Article VI of the Confederation specifically allowed side deals among states, and the Constitution could be viewed as a side deal until all states ratified it.

Final months On July 3, 1788, the Congress received New Hampshire's all-important ninth ratification of the proposed Constitution, thus, according to its terms, establishing it as the new framework of governance for the ratifying states. The following day delegates considered a bill to admit Kentucky into the Union as a sovereign state. The discussion ended with Congress making the determination that, in light of this development, it would be "unadvisable" to admit Kentucky into the Union, as it could do so "under the Articles of Confederation" only, but not "under the Constitution". By the end of July 1788, 11 of the 13 states had ratified the new Constitution. Congress continued to convene under the Articles with a quorum until October. On Saturday, September 13, 1788, the Confederation Congress voted the resolve to implement the new Constitution, and on Monday, September 15 published an announcement that the new Constitution had been ratified by the necessary nine states, set the first Wednesday in January 1789 for appointing electors, set the first Wednesday in February 1789 for the presidential electors to meet and vote for a new president, and set the first Wednesday of March 1789 as the day "for commencing proceedings" under the new Constitution. On that same September 13, it determined that New York would remain the national capital.

Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean at about 8°N. Scientific explorations of the Atlantic include the Challenger expedition, the German Meteor expedition, Columbia University's Lamont-Doherty Earth Observatory and the United States Navy Hydrographic Office. Etymology The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): (Greek: ; English: 'the Atlantic sea'; etym. 'Sea of Atlas') and in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): (Greek: ; English: 'Sea of Atlas' or 'the Atlantic sea') where the name refers to "the sea beyond the pillars of Heracles" which is said to be part of the sea that surrounds all land. In these uses, the name refers to Atlas, the Titan in Greek mythology, who supported the heavens and who later appeared as a frontispiece in Medieval maps and also lent his name to modern atlases. On the other hand, to early Greek sailors and in Ancient Greek mythological literature such as the Iliad and the Odyssey, this all-encompassing ocean was instead known as Oceanus, the gigantic river that encircled the world; in contrast to the enclosed seas well known to the Greeks: the Mediterranean and the Black Sea. In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of millions of years ago. The term "Aethiopian Ocean", derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century. During the Age of Discovery, the Atlantic was also known to English cartographers as the Great Western Ocean. The pond is a term often used by British and American speakers in reference to the Northern Atlantic Ocean, as a form of meiosis, or ironic understatement. It is used mostly when referring to events or circumstances "on this side of the pond" or "on the other side of the pond", rather than to discuss the ocean itself.

It is used mostly when referring to events or circumstances "on this side of the pond" or "on the other side of the pond", rather than to discuss the ocean itself.

The term dates to 1640, first appearing in print in pamphlet released during the reign of Charles I, and reproduced in 1869 in Nehemiah Wallington's Historical Notices of Events Occurring Chiefly in The Reign of Charles I, where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank, Charles I's Secretary of State. Extent and data The International Hydrographic Organization (IHO) defined the limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not used by various authorities, institutions, and countries, see for example the CIA World Factbook. Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea. To the east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea—one of its marginal seas—and, in turn, the Black Sea, both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean. The Atlantic has irregular coasts indented by numerous bays, gulfs and seas. These include the Baltic Sea, Black Sea, Caribbean Sea, Davis Strait, Denmark Strait, part of the Drake Passage, Gulf of Mexico, Labrador Sea, Mediterranean Sea, North Sea, Norwegian Sea, almost all of the Scotia Sea, and other tributary water bodies. Including these marginal seas the coast line of the Atlantic measures compared to for the Pacific. Including its marginal seas, the Atlantic covers an area of or 23.5% of the global ocean and has a volume of or 23.3% of the total volume of the earth's oceans. Excluding its marginal seas, the Atlantic covers and has a volume of . The North Atlantic covers (11.5%) and the South Atlantic (11.1%). The average depth is and the maximum depth, the Milwaukee Deep in the Puerto Rico Trench, is .

It runs from 87°N or south of the North Pole to the subantarctic Bouvet Island at 54°S. Mid-Atlantic Ridge The MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above along most of its length, but is interrupted by larger transform faults at two places: the Romanche Trench near the Equator and the Gibbs Fracture Zone at 53°N. The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other. The MAR rises above the surrounding ocean floor and its rift valley is the divergent boundary between the North American and Eurasian plates in the North Atlantic and the South American and African plates in the South Atlantic. The MAR produces basaltic volcanoes in Eyjafjallajökull, Iceland, and pillow lava on the ocean floor. The depth of water at the apex of the ridge is less than in most places, while the bottom of the ridge is three times as deep. The MAR is intersected by two perpendicular ridges: the Azores–Gibraltar Transform Fault, the boundary between the Nubian and Eurasian plates, intersects the MAR at the Azores Triple Junction, on either side of the Azores microplate, near the 40°N.

From October to June the surface is usually covered with sea ice in the Labrador Sea, Denmark Strait, and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as the North Atlantic oscillation, occurs. Salinity On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Although the lowest salinity values are just north of the equator (because of heavy tropical rainfall), in general, the lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south, in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings, which brings salty Indian Ocean waters into the South Atlantic, and the "Atmospheric Bridge", which evaporates subtropical Atlantic waters and exports it to the Pacific. Water masses The Atlantic Ocean consists of four major, upper water masses with distinct temperature and salinity. The Atlantic Subarctic Upper Water in the northernmost North Atlantic is the source for Subarctic Intermediate Water and North Atlantic Intermediate Water. North Atlantic Central Water can be divided into the Eastern and Western North Atlantic central Water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean Water. North Atlantic Central Water flows into South Atlantic Central Water at 15°N. There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic Intermediate Water, flows from north to become the source for North Atlantic Deep Water south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and the large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic Deep Water (NADW) is a complex of four water masses, two that form by deep convection in the open ocean — Classical and Upper Labrador Sea Water — and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill — Denmark Strait and Iceland-Scotland Overflow Water. Along its path across Earth the composition of the NADW is affected by other water masses, especially Antarctic Bottom Water and Mediterranean Overflow Water.

The NADW is fed by a flow of warm shallow water into the northern North Atlantic which is responsible for the anomalous warm climate in Europe. Changes in the formation of NADW have been linked to global climate changes in the past. Since man-made substances were introduced into the environment, the path of the NADW can be traced throughout its course by measuring tritium and radiocarbon from nuclear weapon tests in the 1960s and CFCs. Gyres The clockwise warm-water North Atlantic Gyre occupies the northern Atlantic, and the counter-clockwise warm-water South Atlantic Gyre appears in the southern Atlantic. In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level. The subpolar gyre forms an important part of the global thermohaline circulation. Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from the subtropics to the north-eastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv) current which flows around the continental margins of the Labrador Sea. A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in its turn, feeds the meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation, are especially pronounced in Labrador Sea Water, the upper layers of the MOC. The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The South Atlantic Central Water originates in this gyre, while Antarctic Intermediate Water originates in the upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer. The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below the thermocline of the subtropical gyre.

In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level. The subpolar gyre forms an important part of the global thermohaline circulation. Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from the subtropics to the north-eastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv) current which flows around the continental margins of the Labrador Sea. A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in its turn, feeds the meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation, are especially pronounced in Labrador Sea Water, the upper layers of the MOC. The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The South Atlantic Central Water originates in this gyre, while Antarctic Intermediate Water originates in the upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer. The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below the thermocline of the subtropical gyre.

Sargasso Sea The Sargasso Sea in the western North Atlantic can be defined as the area where two species of Sargassum (S. fluitans and natans) float, an area wide and encircled by the Gulf Stream, North Atlantic Drift, and North Equatorial Current. This population of seaweed probably originated from Tertiary ancestors on the European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth, floating in the ocean for millions of years. Other species endemic to the Sargasso Sea include the sargassum fish, a predator with algae-like appendages which hovers motionless among the Sargassum. Fossils of similar fishes have been found in fossil bays of the former Tethys Ocean, in what is now the Carpathian region, that were similar to the Sargasso Sea. It is possible that the population in the Sargasso Sea migrated to the Atlantic as the Tethys closed at the end of the Miocene around 17 Ma. The origin of the Sargasso fauna and flora remained enigmatic for centuries. The fossils found in the Carpathians in the mid-20th century often called the "quasi-Sargasso assemblage", finally showed that this assemblage originated in the Carpathian Basin from where it migrated over Sicily to the Central Atlantic where it evolved into modern species of the Sargasso Sea. The location of the spawning ground for European eels remained unknown for decades. In the early 19th century it was discovered that the southern Sargasso Sea is the spawning ground for both the European and American eel and that the former migrate more than and the latter . Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and Northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. Climate Climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of the ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of the atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across the Atlantic north of the equator. The coldest zones are in high latitudes, with the coldest regions corresponding to the areas covered by sea ice. Ocean currents influence the climate by transporting warm and cold waters to other regions. The winds that are cooled or warmed when blowing over these currents influence adjacent land areas. The Gulf Stream and its northern extension towards Europe, the North Atlantic Drift is thought to have at least some influence on climate. For example, the Gulf Stream helps moderate winter temperatures along the coastline of southeastern North America, keeping it warmer in winter along the coast than inland areas.

The Gulf Stream also keeps extreme temperatures from occurring on the Florida Peninsula. In the higher latitudes, the North Atlantic Drift, warms the atmosphere over the oceans, keeping the British Isles and north-western Europe mild and cloudy, and not severely cold in winter like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's north-western coast. In general, winds transport moisture and air over land areas. Natural hazards Every winter, the Icelandic Low produces frequent storms. Icebergs are common from early February to the end of July across the shipping lanes near the Grand Banks of Newfoundland. The ice season is longer in the polar regions, but there is little shipping in those areas. Hurricanes are a hazard in the western parts of the North Atlantic during the summer and autumn. Due to a consistently strong wind shear and a weak Intertropical Convergence Zone, South Atlantic tropical cyclones are rare. Geology and plate tectonics The Atlantic Ocean is underlain mostly by dense mafic oceanic crust made up of basalt and gabbro and overlain by fine clay, silt and siliceous ooze on the abyssal plain. The continental margins and continental shelf mark lower density, but greater thickness felsic continental rock that is often much older than that of the seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and situated off the west coast of Africa and east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and the Bahamas, while coarse river outwash sands and silt are common in shallow shelf areas like the Georges Bank. Coarse sand, boulders, and rocks were transported into some areas, such as off the coast of Nova Scotia or the Gulf of Maine during the Pleistocene ice ages. Central Atlantic The break-up of Pangaea began in the Central Atlantic, between North America and Northwest Africa, where rift basins opened during the Late Triassic and Early Jurassic. This period also saw the first stages of the uplift of the Atlas Mountains. The exact timing is controversial with estimates ranging from 200 to 170 Ma. The opening of the Atlantic Ocean coincided with the initial break-up of the supercontinent Pangaea, both of which were initiated by the eruption of the Central Atlantic Magmatic Province (CAMP), one of the most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event, one of Earth's major extinction events. Theoliitic dikes, sills, and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America.

The extent of the volcanism has been estimated to of which covered what is now northern and central Brazil. The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago. The formation of the isthmus resulted in the migration and extinction of many land-living animals, known as the Great American Interchange, but the closure of the seaway resulted in a "Great American Schism" as it affected ocean currents, salinity, and temperatures in both the Atlantic and Pacific. Marine organisms on both sides of the isthmus became isolated and either diverged or went extinct. Geologically, the Northern Atlantic is the area delimited to the south by two conjugate margins, Newfoundland and Iberia, and to the north by the Arctic Eurasian Basin. The opening of the Northern Atlantic closely followed the margins of its predecessor, the Iapetus Ocean, and spread from the Central Atlantic in six stages: Iberia–Newfoundland, Porcupine–North America, Eurasia–Greenland, Eurasia–North America. Active and inactive spreading systems in this area are marked by the interaction with the Iceland hotspot. Seafloor spreading led to the extension of the crust and formations of troughs and sedimentary basins. The Rockall Trough opened between 105 and 84 million years ago although along the rift failed along with one leading into the Bay of Biscay. Spreading began opening the Labrador Sea around 61 million years ago, continuing until 36 million years ago. Geologists distinguish two magmatic phases. One from 62 to 58 million years ago predates the separation of Greenland from northern Europe while the second from 56 to 52 million years ago happened as the separation occurred. Iceland began to form 62 million years ago due to a particularly concentrated mantle plume. Large quantities of basalt erupted at this time period are found on Baffin Island, Greenland, the Faroe Islands, and Scotland, with ash falls in Western Europe acting as a stratigraphic marker. The opening of the North Atlantic caused significant uplift of continental crust along the coast. For instance, in spite of 7 km thick basalt, Gunnbjorn Field in East Greenland is the highest point on the island, elevated enough that it exposes older Mesozoic sedimentary rocks at its base, similar to old lava fields above sedimentary rocks in the uplifted Hebrides of western Scotland. The North Atlantic Ocean contains about 810 seamounts, most of them situated along the Mid-Atlantic Ridge. The OSPAR database (Convention for the Protection of the Marine Environment of the North-East Atlantic) mentions 104 seamounts: 74 within the national Exclusive economic zone. Of these seamounts, 46 are located close to the Iberian Peninsula. South Atlantic West Gondwana (South America and Africa) broke up in the Early Cretaceous to form the South Atlantic. The apparent fit between the coastlines of the two continents was noted on the first maps that included the South Atlantic and it was also the subject of the first computer-assisted plate tectonic reconstructions in 1965.

The apparent fit between the coastlines of the two continents was noted on the first maps that included the South Atlantic and it was also the subject of the first computer-assisted plate tectonic reconstructions in 1965.

This magnificent fit, however, has since then proven problematic and later reconstructions have introduced various deformation zones along the shorelines to accommodate the northward-propagating break-up. Intra-continental rifts and deformations have also been introduced to subdivide both continental plates into sub-plates. Geologically the South Atlantic can be divided into four segments: Equatorial segment, from 10°N to the Romanche Fracture Zone (RFZ); Central segment, from RFZ to Florianopolis Fracture Zone (FFZ, north of Walvis Ridge and Rio Grande Rise); Southern segment, from FFZ to the Agulhas-Falkland Fracture Zone (AFFZ); and Falkland segment, south of AFFZ. In the southern segment the Early Cretaceous (133–130 Ma) intensive magmatism of the Paraná–Etendeka Large Igneous Province produced by the Tristan hotspot resulted in an estimated volume of . It covered an area of in Brazil, Paraguay, and Uruguay and in Africa. Dyke swarms in Brazil, Angola, eastern Paraguay, and Namibia, however, suggest the LIP originally covered a much larger area and also indicate failed rifts in all these areas. Associated offshore basaltic flows reach as far south as the Falkland Islands and South Africa. Traces of magmatism in both offshore and onshore basins in the central and southern segments have been dated to 147–49 Ma with two peaks between 143 and 121 Ma and 90–60 Ma. In the Falkland segment rifting began with dextral movements between the Patagonia and Colorado sub-plates between the Early Jurassic (190 Ma) and the Early Cretaceous (126.7 Ma). Around 150 Ma sea-floor spreading propagated northward into the southern segment. No later than 130 Ma rifting had reached the Walvis Ridge–Rio Grande Rise. In the central segment rifting started to break Africa in two by opening the Benue Trough around 118 Ma. Rifting in the central segment, however, coincided with the Cretaceous Normal Superchron (also known as the Cretaceous quiet period), a 40 Ma period without magnetic reversals, which makes it difficult to date sea-floor spreading in this segment. The equatorial segment is the last phase of the break-up, but, because it is located on the Equator, magnetic anomalies cannot be used for dating. Various estimates date the propagation of sea-floor spreading in this segment to the period 120–96 Ma. This final stage, nevertheless, coincided with or resulted in the end of continental extension in Africa. About 50 Ma the opening of the Drake Passage resulted from a change in the motions and separation rate of the South American and Antarctic plates. First small ocean basins opened and a shallow gateway appeared during the Middle Eocene. 34–30 Ma a deeper seaway developed, followed by an Eocene–Oligocene climatic deterioration and the growth of the Antarctic ice sheet. Closure of the Atlantic An embryonic subduction margin is potentially developing west of Gibraltar. The Gibraltar Arc in the western Mediterranean is migrating westward into the Central Atlantic where it joins the converging African and Eurasian plates. Together these three tectonic forces are slowly developing into a new subduction system in the eastern Atlantic Basin.

In the central segment rifting started to break Africa in two by opening the Benue Trough around 118 Ma. Rifting in the central segment, however, coincided with the Cretaceous Normal Superchron (also known as the Cretaceous quiet period), a 40 Ma period without magnetic reversals, which makes it difficult to date sea-floor spreading in this segment. The equatorial segment is the last phase of the break-up, but, because it is located on the Equator, magnetic anomalies cannot be used for dating. Various estimates date the propagation of sea-floor spreading in this segment to the period 120–96 Ma. This final stage, nevertheless, coincided with or resulted in the end of continental extension in Africa. About 50 Ma the opening of the Drake Passage resulted from a change in the motions and separation rate of the South American and Antarctic plates. First small ocean basins opened and a shallow gateway appeared during the Middle Eocene. 34–30 Ma a deeper seaway developed, followed by an Eocene–Oligocene climatic deterioration and the growth of the Antarctic ice sheet. Closure of the Atlantic An embryonic subduction margin is potentially developing west of Gibraltar. The Gibraltar Arc in the western Mediterranean is migrating westward into the Central Atlantic where it joins the converging African and Eurasian plates. Together these three tectonic forces are slowly developing into a new subduction system in the eastern Atlantic Basin.

Meanwhile, the Scotia Arc and Caribbean Plate in the western Atlantic Basin are eastward-propagating subduction systems that might, together with the Gibraltar system, represent the beginning of the closure of the Atlantic Ocean and the final stage of the Atlantic Wilson cycle. History Human origin Humans evolved in Africa; first by diverging from other apes around 7 mya; then developing stone tools around 2.6 mya; to finally evolve as modern humans around 200 kya. The earliest evidence for the complex behavior associated with this behavioral modernity has been found in the Greater Cape Floristic Region (GCFR) along the coast of South Africa. During the latest glacial stages, the now-submerged plains of the Agulhas Bank were exposed above sea level, extending the South African coastline farther south by hundreds of kilometers. A small population of modern humans — probably fewer than a thousand reproducing individuals — survived glacial maxima by exploring the high diversity offered by these Palaeo-Agulhas plains. The GCFR is delimited to the north by the Cape Fold Belt and the limited space south of it resulted in the development of social networks out of which complex Stone Age technologies emerged. Human history thus begins on the coasts of South Africa where the Atlantic Benguela Upwelling and Indian Ocean Agulhas Current meet to produce an intertidal zone on which shellfish, fur seal, fish and sea birds provided the necessary protein sources. The African origin of this modern behaviour is evidenced by 70,000 years-old engravings from Blombos Cave, South Africa. Old World Mitochondrial DNA (mtDNA) studies indicate that 80–60,000 years ago a major demographic expansion within Africa, derived from a single, small population, coincided with the emergence of behavioral complexity and the rapid MIS 5–4 environmental changes. This group of people not only expanded over the whole of Africa, but also started to disperse out of Africa into Asia, Europe, and Australasia around 65,000 years ago and quickly replaced the archaic humans in these regions. During the Last Glacial Maximum (LGM) 20,000 years ago humans had to abandon their initial settlements along the European North Atlantic coast and retreat to the Mediterranean. Following rapid climate changes at the end of the LGM this region was repopulated by Magdalenian culture. Other hunter-gatherers followed in waves interrupted by large-scale hazards such as the Laacher See volcanic eruption, the inundation of Doggerland (now the North Sea), and the formation of the Baltic Sea. The European coasts of the North Atlantic were permanently populated about 9–8.5 thousand years ago. This human dispersal left abundant traces along the coasts of the Atlantic Ocean. 50 kya-old, deeply stratified shell middens found in Ysterfontein on the western coast of South Africa are associated with the Middle Stone Age (MSA). The MSA population was small and dispersed and the rate of their reproduction and exploitation was less intense than those of later generations.

The MSA population was small and dispersed and the rate of their reproduction and exploitation was less intense than those of later generations.

While their middens resemble 12–11 kya-old Late Stone Age (LSA) middens found on every inhabited continent, the 50–45 kya-old Enkapune Ya Muto in Kenya probably represents the oldest traces of the first modern humans to disperse out of Africa. The same development can be seen in Europe. In La Riera Cave (23–13 kya) in Asturias, Spain, only some 26,600 molluscs were deposited over 10 kya. In contrast, 8–7 kya-old shell middens in Portugal, Denmark, and Brazil generated thousands of tons of debris and artefacts. The Ertebølle middens in Denmark, for example, accumulated of shell deposits representing some 50 million molluscs over only a thousand years. This intensification in the exploitation of marine resources has been described as accompanied by new technologies — such as boats, harpoons, and fish-hooks — because many caves found in the Mediterranean and on the European Atlantic coast have increased quantities of marine shells in their upper levels and reduced quantities in their lower. The earliest exploitation, however, took place on the now submerged shelves, and most settlements now excavated were then located several kilometers from these shelves. The reduced quantities of shells in the lower levels can represent the few shells that were exported inland. New World During the LGM the Laurentide Ice Sheet covered most of northern North America while Beringia connected Siberia to Alaska. In 1973, late American geoscientist Paul S. Martin proposed a "blitzkrieg" colonization of the Americas by which Clovis hunters migrated into North America around 13,000 years ago in a single wave through an ice-free corridor in the ice sheet and "spread southward explosively, briefly attaining a density sufficiently large to overkill much of their prey." Others later proposed a "three-wave" migration over the Bering Land Bridge. These hypotheses remained the long-held view regarding the settlement of the Americas, a view challenged by more recent archaeological discoveries: the oldest archaeological sites in the Americas have been found in South America; sites in north-east Siberia report virtually no human presence there during the LGM; and most Clovis artefacts have been found in eastern North America along the Atlantic coast. Furthermore, colonisation models based on mtDNA, yDNA, and atDNA data respectively support neither the "blitzkrieg" nor the "three-wave" hypotheses but they also deliver mutually ambiguous results. Contradictory data from archaeology and genetics will most likely deliver future hypotheses that will, eventually, confirm each other. A proposed route across the Pacific to South America could explain early South American finds and another hypothesis proposes a northern path, through the Canadian Arctic and down the North American Atlantic coast. Early settlements across the Atlantic have been suggested by alternative theories, ranging from purely hypothetical to mostly disputed, including the Solutrean hypothesis and some of the Pre-Columbian trans-oceanic contact theories. The Norse settlement of the Faroe Islands and Iceland began during the 9th and 10th centuries. A settlement on Greenland was established before 1000 CE, but contact with it was lost in 1409 and it was finally abandoned during the early Little Ice Age.

A settlement on Greenland was established before 1000 CE, but contact with it was lost in 1409 and it was finally abandoned during the early Little Ice Age.

This setback was caused by a range of factors: an unsustainable economy resulted in erosion and denudation, while conflicts with the local Inuit resulted in the failure to adapt their Arctic technologies; a colder climate resulted in starvation, and the colony got economically marginalized as the Great Plague and Barbary pirates harvested its victims on Iceland in the 15th century. Iceland was initially settled 865–930 CE following a warm period when winter temperatures hovered around which made farming favorable at high latitudes. This did not last, however, and temperatures quickly dropped; at 1080 CE summer temperatures had reached a maximum of . The Landnámabók (Book of Settlement) records disastrous famines during the first century of settlement — "men ate foxes and ravens" and "the old and helpless were killed and thrown over cliffs" — and by the early 1200s hay had to be abandoned for short-season crops such as barley. Atlantic World Christopher Columbus reached the Americas in 1492 under Spanish flag. Six years later Vasco da Gama reached India under the Portuguese flag, by navigating south around the Cape of Good Hope, thus proving that the Atlantic and Indian Oceans are connected. In 1500, in his voyage to India following Vasco da Gama, Pedro Alvares Cabral reached Brazil, taken by the currents of the South Atlantic Gyre. Following these explorations, Spain and Portugal quickly conquered and colonized large territories in the New World and forced the Amerindian population into slavery in order to explore the vast quantities of silver and gold they found. Spain and Portugal monopolized this trade in order to keep other European nations out, but conflicting interests nevertheless led to a series of Spanish-Portuguese wars. A peace treaty mediated by the Pope divided the conquered territories into Spanish and Portuguese sectors while keeping other colonial powers away. England, France, and the Dutch Republic enviously watched the Spanish and Portuguese wealth grow and allied themselves with pirates such as Henry Mainwaring and Alexandre Exquemelin. They could explore the convoys leaving the Americas because prevailing winds and currents made the transport of heavy metals slow and predictable. In the colonies of the Americas, depredation, smallpox and others diseases, and slavery quickly reduced the indigenous population of the Americas to the extent that the Atlantic slave trade had to be introduced to replace them — a trade that became the norm and an integral part of the colonization. Between the 15th century and 1888, when Brazil became the last part of the Americas to end the slave trade, an estimated ten million Africans were exported as slaves, most of them destined for agricultural labour. The slave trade was officially abolished in the British Empire and the United States in 1808, and slavery itself was abolished in the British Empire in 1838 and in the United States in 1865 after the Civil War. From Columbus to the Industrial Revolution Trans-Atlantic trade, including colonialism and slavery, became crucial for Western Europe.
