Product Description
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. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.
The quest for a solution has occupied scientists for the better part of two centuries when, in 1714, England's parliament upped the ante by offering a king's ransom (£20,000, or approximately $12 million in today's currency) to anyone whose method or device proved successful and reproducible. The scientific establishment throughout Europe—from Galileo to Sir Isaac Newton—had mapped the heavens in its pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to image 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 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. Through Dava Sobel's consummate skill, Longitude opens many new windows on our world.
"As much a tale of intrigue as it is of science . . . A book full of gems for anyone interested in history, geography, astronomy, navigation, clock making, and—not the least—plain old human ambition and greed."—The Philadelphia Inquirer
"This is a gem of a book."—The New York Times
"A simple tale, brilliantly told."—The Washington Post Book World
"Intricate and elegant . . . No novelist could improve on the elements of Dava Sobel's achievement."—Newsweek
"An exquisitely done narrative of the chronometer. It is a wonderful and engrossing achievement."—William F. Buckley, Jr.
"Only someone with Dava Sobel's unusual background in both astronomy and psychology could have written it. Longitude is a wonderful story, wonderfully told."—Diane Ackerman, author of A Natural History of the Senses

Amazon.com Review
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 School Library Journal
YA?Opening with a chapter that outlines what follows, Sobel whets readers' appetites for hearing the colorful details of the search for a way for mariners to determine longitude. In an age when ships' stores were limited and scurvy killed many a seaman, missing a landfall often meant death?as, of course, did running aground. Sobel provides a lively treatment of the search through the centuries for a ready answer to the longitude problem, either through using lunar tables or through making an accurate clock not subject to the vicissitudes of weather and ocean conditions. Her account includes not only scientific advances, but also the perseverance, pettiness, politics, and interesting anecdotes that figured in along the way (it wasn't limes, for example, that first prevented scurvy on English ships, but sauerkraut). A pleasing mixture of basic science, cultural history, and personality conflicts makes this slim volume a winner.?Judy McAloon, Potomac Library, Prince William County, VA

Simple guy solves enormous problem
If you can't get Newton and Galileo to solve your scientific problems, who do you turn to? Well the English government turned to everyone, hoping that some budding scientist could figure out the problem of calculating Longitude at sea. They even offered a huge reward. Why was it important? Without precise longitude, there was no way to steer a ship with any precision. Thus English ships were being wrecked and precious cargo wasn't making its scheduled delivery.
The scientists worked and worked on the problem. Many men including Edmund Halley thought that by mapping the stars, one could use the night sky as a map at sea. Although he knew little about science, a simple clockmaker named John Harrison thought that well-built clock with a dual face would solve the problem. You get to guess which person was right.
Longitude is both a vibrant story of the pains of solving an important problem, and a biography of the man who solved it. I don't tend to read the subject of science all that much, because I find it dry, but not so with this book. Author Dava Sobel lends an understanding of the human element in science. That Harrison has to fight snobbery first and later jealousy demonstrates how ego and self-importance can get in the way of the most important problems facing human beings. Not only will you learn how average people can solve enormous tasks, but you'll nod as the familiar self-promoters try to take the credit.
A Good Beach or Airplane Book
This is a highly readable little book, and I recommend it, with a few caveats.
Sobel presents her material logically and lucidly. She is a good prose stylist and is obviously an accomplished reporter. This book, however, feels like what it is: a series of articles stretched out a little to accomodate a best-seller format. The story is an intriguing one. An 18th century inventor rises from obscurity and against great odds and bias, produces an instrument that will prove of enormous benefit to his country and to humankind.
Just don't go into the reading of this book expecting great historical writing. Sobel acknowledges in a postscript that she doesn't include footnotes "because this book is intended as a popular account, not a scholarly study...". She has culled her research, for the most part, from interviewing historians, attending a seminar, and visiting various sites in England. At least she is forthright about her methodology, so she won't have to face the gauntlet that Kearns-Goodwin and Ambrose have recently had to run (mixed metaphor?).
Another minor irritation arises from the fact that one of the prominent blurbs one finds when opening the book comes from Diane Ackerman, whom Sobel later indentifies in her list of acknowledgments as her "dear friend." Again, at least she's being transparent about it, but it still strikes me as a bit disingenuous.
To her credit, Sobel does include a rather comprehensive bibliography, so those who want to further investigate Harrison's achievement are well guided.
Longitude is a good, quick summer read. For those who want some pith with their punch, however, I would recommend the A&E Sturridge video or CD adapted from this work.
A really interesting read.
If you never knew before what a major problem it was before the world knew how to measure longitude (and I certainly didn't), Dava Sobel tells of both the problem and the man who finally solved it in this easy-to-understand and interesting book. Meet John Harrison, the clockmaker/genius who fights the British scientific establishment to prove his method of measuring longitude does work. I found this book to be a quick, interesting read on a topic, and a man, most people don't know anything about, but should.
