Product Description

An exciting scientific adventure from the days of wooden ships and iron men, LONGITUDE is full of heroism and chicanery, brilliance and the absurd. It is also a captivating brief history of astronomy, navigation and clockmaking.

During the great ages of exploration, "the longitude problem" was the gravest of all scientific challenges. Lacking the ability to determine their longitude, sailors were literally lost at sea as soon as they lost sight of land. Ships ran aground on rocky shores; those traveling well-known routes were easy prey to pirates.

In 1714, England's Parliament offered a huge reward to anyone whose method of measuring longitude could be proven successful. The scientific establishment--from Galileo to Sir Isaac Newton--had mapped the heavens in its certainty 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 been able to do on land. And the race was on....

The thorniest scientific problem of the eighteenth century was how to determine longitude. Many thousands of lives had been lost at sea over the centuries due to the inability to determine an east-west position. This is the engrossing story of the clockmaker, John "Longitude" Harrison, who solved the problem that Newton and Galileo had failed to conquer, yet claimed only half the promised rich reward.

From Publishers Weekly
This look at the scientific quest to find a way for ships at sea to determine their longitude was a PW bestseller for eight weeks.

From Library Journal
We take so much for granted. Few of us have ever thought about why and how sailors navigate without becoming lost the moment land is no longer in sight. In fact, prior to the 18th century, whole navies, thousands of lives, and great fortunes were lost because no one knew how to measure longitude. Here is the story of the growing need, the parliamentary offers of huge awards, the politics, the frustrations, and the eventual success of John Harrison. An unschooled woodworker, Harrison developed the chronometer, which was much criticized at the outset in part because competition for the princely rewards was so fierce. The interlocking histories of astronomy, clocks, and navigation reveal the significance of the problem to the seagoing world, the parallel efforts to find answers, and Harrison's drive for perfection and resolution. While the complexities of the problems and personalities are not always easy to follow here, this abridged recording is nonetheless an interesting chronicle of scientific achievement. Reader Jane Jacobs consistently narrates in a clear and distinct manner. Libraries with collections in seafaring and scientific adventure should acquire.?Carolyn Alexander, Columbia Lib.
