- 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
- & 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 l&. Thousands of lives & the increasing fortunes of nations hung on a resolution. The quest for a solution had occupied scientists & 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 & chicanery brilliance & the absurd LONGITUDE is also a fascinating brief history of astronomy navigation & clockmaking.
