who published the first map that showed the new world as separate from asia
Waldseemüller map While some maps after 1500 show, with ambiguity, an eastern coastline for Asia distinct from the Americas, the Waldseemüller map apparently indicates the existence of a new ocean between the trans-Atlantic regions of the Spanish discoveries and the Asia of Ptolemy and Marco Polo as exhibited on the 1492 Behaim globe. The first historical records of Europeans to set eyes on this ocean, the Pacific, are recorded as Vasco Núñez de Balboa in 1513. That is five to six years after Waldseemüller made his map. In addition, the map apparently predicts the width of South America at certain latitudes to within 70 miles.[4] However, as pointed out by E.G. Ravenstein, this is an illusory effect of the cordiform projection used by Waldseemüller, for when the map is laid out on a more familiar equirectangular projection and compared with others of the period also set out on that same projection there is little difference between them: this is particularly evident when the comparison is made with Johannes Schöner's 1515 globe.[5]
Second World The concept of "Second World" was a construct of the Cold War and the term is still largely used to describe former communist countries that are between poverty and prosperity, many of which are now capitalist states. Subsequently the actual meaning of the terms "First World", "Second World" and "Third World" changed from being based on political ideology to an economic definition.[1] The three-world theory has been criticized as crude and relatively outdated for its nominal ordering (1; 2; 3) and sociologists have instead used the words "developed", "developing", and "underdeveloped" as replacement terms for global stratification (which in turn have been criticized as displaying a colonialist mindset) [2] â€”nevertheless, the three-world theory is still popular in contemporary literature and media. This might also cause semantic variation of the term between describing a region's political entities and its people.[3]
