Longitude : The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time
Longitude The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time Author:Dava Sobel Anyone alive in the eighteenth 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. Thou... more »sands of lives, and the increasing fortunes of nations, hung on a resolution.
The scientific establishment of 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—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 clockmaking, and opens a new window on our world.« less

Not a book with footnotes, but pleasant to read and my copy is the 14th printing, so it has sold well--a book about 18th C. technology! I think I liked best the last chapter, where the author visits the observatory at Greenwich.....

My sextant is in storage, my sailboat racing days gone, and I've forgotten how to be first over the line anyway. However, this book brought some of it back to me in a very entertaining way. I wish it had been available to me back in the old days when boredom took over in those doldrums.
Ms. Sobel has done a good job of making the longitude problem interesting. Many documentary makers could have used her input. I highly recommend this book to others who may wonder about how sailors survived without GPS and satellites for their computers.
