Kendall's longitude "Lost at sea: every mariner's fear. Maritime navigational tools could find latitude, but finding longitude remained elusive until Harrison developed the reliable sea clock, H4. Building on H4's success, Kendall made a series of nautical timekeepers, K1, K2 and K3. This is the story of the K2 timekeeper; its adventurous voyages, the people it touched, and its place in history. K2's first voyage, accompanied by the young Nelson, was nearly its last in the crushing Arctic ice. The next two expeditions saw it survive kidnappings, nautical intrigue, and gunpowder plots of the American revolutionary wars. The slave coasts of Africa followed. Bligh took K2 on the Bounty, but lost it in a fight with the mutineers in 1789. It was recovered by an American Quaker from Nantucket, only to be stolen by the Spanish. It rode on mules along the Andes before sailing into the Opium Wars. K2 finally returned to Greenwich in 1963."--Provided by the publisher. 2019. • BOOK • 1 copy available. 527
Captain Cook's computer : the life of William Wales, F.R.S. (1734-1798) /by Wendy Wales. A biography of William Wales FRS (1734-98). Wales, a mathematician and astronomer, was employed in 1765 by the Astronomer Royal Nevil Maskelyne at the Royal Observatory Greenwich as a computer, calculating ephemerides that could be used to establish the longitude of a ship, for Maskelyne's Nautical Almanac. Wales was sent by the Royal Society to observe the transit of Venus in 1769 from Hudson Bay and as a result of his work there was invited to accompany Captain James Cook on his second voyage of discovery (1772-75) on HMS Resolution, tasked with testing Larcum Kendall's K1 chronometer. He became Master of the Royal Mathematical School, was elected a Fellow of the Royal Society in 1776, and served as Secretary of the Board of Longitude (1795-98). The author has drawn on Wales's own accounts of his work and travels and provides brief details of the lives of Wales's immediate family and genealogical charts.
