Publisher Description
The dramatic human story of an epic scientific quest: the search for the solution of how to calculate longitude and the unlikely triumph of an English genius. With a Foreword by Neil Armstrong.
‘Sobel has done the impossible and made horology sexy – no mean feat’ New Scientist
Anyone alive in the 18th century would have known that ‘the longitude problem’ was the thorniest scientific dilemma of the day – and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.
The quest for a solution had occupied scientists and their patrons for the better part of two centuries when, in 1714, Parliament upped the ante by offering a king’s ransom (£20,000) to anyone whose method or device proved successful. Countless quacks weighed in with preposterous suggestions. The scientific establishment throughout Europe – from Galileo to Sir Isaac Newton – had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution.
Full of heroism and chicanery, brilliance and the absurd, LONGITUDE is also a fascinating brief history of astronomy, navigation and clockmaking.

Dava Sobel has written a gem of a book…one of the best reads for the non-scientific writing to come along for many a moon." Financial Times
"A true life thriller, jam-packed with political intrigue, international warfare, personal feuds and financial skullduggery." Daily Mail
"Rarely have I enjoyed a book as much as Dava Sobel's Longitude. She has an extraordinary gift of making difficult ideas clear." Daily Telegraph

PUBLISHERS WEEKLY
While sailors can readily gauge latitude by the height of the sun or guiding stars above the horizon, the measurement of longitude bedeviled navigators for centuries, resulting in untold shipwrecks. Galileo, Isaac Newton and Edmund Halley entreated the moon and stars for help, but their astronomical methods failed. In 1714, England's Parliament offered 20,000 (equivalent to millions of dollars today) to anyone who could solve the problem. Self-educated English clockmaker John Harrison (1693-1776) found the answer by inventing a chronometer--a friction-free timepiece, impervious to pitch and roll, temperature and humidity--that would carry the true time from the home port to any destination. But Britain's Board of Longitude, a panel of scientists, naval officers and government officials, favored the astronomers over humble ``mechanics'' like Harrison, who received only a portion of the prize after decades of struggle. Yet his approach ultimately triumphed, enabling Britannia to rule the waves. In an enthralling gem of a book, former New York Times science reporter Sobel spins an amazing tale of political intrigue, foul play, scientific discovery and personal ambition.
