The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem. 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.

One man, 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 clockmaking, and opens a new window on our world. Read more Read less.

Editorial Reviews Amazon. This lush, colorfully illustrated edition adds lots of pictures to the story, giving readers a more satisfying sense of the times, the players, and the puzzle. This was no obscure, curious difficulty--without longitude, ships often found themselves so far off course that sailors would starve or die of scurvy before they could reach port.

When a nationally-sponsored contest offered a hefty cash prize to the person who could develop a method to accurately determine longitude, the race was on. In the end, the battle of accuracy--and wills--fought between Harrison and arch-rival Maskelyne was ruthless and dramatic, worthy of a Hollywood feature film.

Longitude 's story is surprising and fascinating, offering a window into the past, before Global Positioning Satellites made it look easy. 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. Copyright Reed Business Information, Inc. See all Editorial Reviews.

Paperback Verified Purchase. Longitude is west to east, east to west.

But it's not that simple because, for example, the equator is wider around the earth than the Tropic of Capricorn or the Arctic Circle. Although latitude is fixed by the earth and Columbus could sail a "straight line" in relative to a fixed latitudinal parallel, longitude made sailors feel they were on a train and looking at another train, trying to determine which one just began moving.

After reading a book about Mason and Dixon and all of the incredibly for me complex math and astronomy involved, I was slow to begin this book. Author Dava Sobel, however, cuts through all the more complicated principles like a good pre-calculus teacher. I would even suggest this book could appeal to adventurous 8th graders. The history is impressive. The Harrison family were watchmakers, but as very precise and diligent watchmakers competitive with the Royal Society and haughty astronomers like Nevil Maskelyne.

John Harrison had size, cost, material, temperature fluctuations, moisture, waves, and many more atmospheric obstacles to confront while those relying on lunar readings went much further to produce much less.

Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time

For the record, I had never heard of John Harrison. His predecessors include Halley, Tycho Brahe, and Galileo, whose attempts to time the speed of light is briefly retold here.

This is summer reading, a hero's tale, good defeating bad, The Little Engine that Could. If you or your child is interested in sailing, navigation, astronomy, inventions, machining, or how the British came to rule the word for a time, this is a book to read and re-read.

Kindle Edition Verified Purchase. I was left hoping for more detail and depth. This story is sort of a biography about a person whom the author explains there is not much known.

The subject's work product is and has been well known and studied at length, but there are not enough details about the technology included in this book. At the end of the book the author explains that she purposefully omitted information that she did not think her readers are smart enough to consider. The premise of using a clock to compute longitude is mentioned repeatedly through the first half of the book, but an explanation of the operating principal and technique is only finally hinted at in the later stages of the book.

The idea is that at any instant one can correlate "local" time to some known "reference" time as it occurs at some specific reference location and compute the local angle of longitude in relation to the reference location.

The clocks being discussed are the devices used to reliably transport the "reference" time for comparative use in other locales.

I have been aware of the technique for a long while and it became a guessing game to anticipate when the idea was finally going to be presented to, and shared with, readers.

I think that many readers will enjoy the book much more if the premise is described, in detail, in an earlier portion of the story so that it is more obvious why one may appreciate all the great efforts made in the field of horology to achieve a series of incremental advances in performance and reliability. This book reads like a book report or a term paper rather than as a comprehensive book.
