Dava Sobel, former science reporter for The New York Times, wrote an international best seller published in 23 languages when she wrote “Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time.” “In the eighteenth century ‘the longitude problem’ was the thorniest scientific dilemma of the day—and had been for centuries. John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution—a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison’s forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clock making, and opens a new window on our world” (Amazon).
