Read Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time Online Free - On its 10th anniversary, a gift edition of this classic book, with a forward by one of history's greatest explorers, and eight pages of color illustrations.
Anyone alive in the eighteeth century would have known that "the logitude 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 scientific establishment of Europe--from Galileo to Sir Issac 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 a dramatic human story of an epic scientific quest and 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.

Longitude from Dava Sobel is a fascinating account of how a virtually unknown watchmaker named John Harrison conquered one of the oldest and thorniest problems surrounding the ocean voyages - the problem of accurately measuring longitude -, which stumped even the best of scientific minds for cent...

Really lovely and very interesting reading. Everybody knows about longitude but I guess not so many know the struggles and fights behind the tries to 'conquer' it, including myself.
John Harrison was a genius of his times; beside the fact that he produced the first accurate marine watches for calc...

La Historia está llena de pequeños descubrimientos capaces de cambiar el mundo. Aunque debería decir pequeños vistos desde nuestros días. Este es el caso de la longitud, es decir, esas líneas imaginarias que trazan nuestro planeta desde los polos, dividiéndolo en veinticuatro partes iguales. La l...

In Longitude, Dava Sobel chronicles the world's quest to tame time. In 1714, the English Parliament passed the longitude act. It established the Board of Longitude and offered a prize of 20,000 pounds to anyone who could find a simple and practical method for the precise determination of a ship's...

"The British Parliament, in its famed Longitude Act of 1714, set the highest bounty of all, naming a prize equal to a king’s ransom (several million dollars in today’s currency) for a “Practicable and Useful” means of determining longitude.”
I read this historical and biographical account in one...

An amazing book.

This book was intended for the general reader. Consequently it did not deal much with the details either of the astronomical or mechanical approaches to solving the problem of finding longitude on the high seas. Instead it focused on description of John Harrison's quest to build an ocean chronome...

On October 22, 1707 four English warships crashed into the rocks of the Scilly Isles southwest of England. They quickly sank killing 2,000 men. The cause of this catastrophe was the inability to determine longitude, a problem that beset mariners everywhere. In 1714 the British Parliament set a £2...

I was reminded of this book today because in was on the PageADay Book Lover's Calendar for 3-31-2015. I read it back in the year 2000(+-). I have favorable recollections of the book, and I found it to be in interesting story. The following short review is copied from the calendar.

I take GPS for granted. I don’t use it that much personally, because I don’t tend to go anywhere, but I’m sure all this technology I love to use makes use of GPS. Thanks to GPS, we can forget that calculating longitude without the help of a network of satellites is difficult and requires great ma...
