Charles Lyell Sir Charles Lyell, 1st Baronet, {'1': ", '2': ", '3': ", '4': "} (14 November 1797 – 22 February 1875) was a Scottish geologist who popularised the revolutionary work of James Hutton. He is best known as the author of "Principles of Geology", which presented uniformitarianism–the idea that the Earth was shaped by the same scientific processes still in operation today–to the broad general public. "Principles of Geology" also challenged theories popularised by Georges Cuvier, which were the most accepted and circulated ideas about geology in Europe at the time.
Aku-Aku Aku-Aku: the Secret of Easter Island is a 1957 book by Thor Heyerdahl published in English the following year. The book describes the 1955–1956 Norwegian Archaeological Expedition's investigations of Polynesian history and culture at Easter Island, the Austral Islands of Rapa Iti and Raivavae, and the Marquesas Islands of Nuku Hiva and Hiva Oa. Visits to Pitcairn Island, Mangareva and Tahiti are described as well. By far the greatest part of the book tells of the work on Easter Island, where the expedition investigated the giant stone statues ("moai"), the quarries at Rano Raraku and Puna Pau, the ceremonial village of Orongo on Rano Kau, as well as many other sites throughout the island. Much of the book's interest derives from the interaction of the expedition staff, from their base at Anakena beach, with the Easter Islanders themselves, who lived mainly in the village of Hanga Roa.
