圖書描述

The tenth anniversary edition of 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 new Foreword by the celebrated astronaut 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 (GBP20,000) 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.

真實的故事，卻比小說更精彩！John Harrison 從一開始為瞭2萬英鎊的巨額奬金開始研究航海鍾，到後來不斷自我突破刷新計時精度，H1,H2,H3,H4,花費數十年窮其一生，不斷推進航海鍾的創新。雖然後期在時鍾法與天體觀測法的爭鬥中受到不公正的待遇，但最終Harrion證明瞭自身偉大的價值。高精度航海鍾的發明，為大航海時代掃除瞭障礙，為日不落帝國的崛起作齣卓越貢獻！有機會定要去倫敦市政廳，參觀下那些代錶技術文明榮耀的展品！
