Written by Dava Sobel, this book is about one of the greatest problems that baffled people for centuries: the problem of longitude. Centuries ago, sailors were unable to navigate the seas with the ease and effectiveness as today’s people. While scientists and nations were unable to successfully solve the problem, many shipwrecks and deaths continued at sea. However, as time passed, progress was made in solving the problem and measuring longitude effectively. This book takes readers on that journey, and it shows how the collective ideas of people over time helped change travel over sea, and to some extent, it reshaped the world. People who are interested in science, geography, history, and navigation may find the book interesting. However, even though it is well-written and informative, I found it quite boring, which is why I would give it 3.5 stars.

A lone genius he was, with no equal in our time. The book covers not only his (lunar distance) rivals, but also the more successful "entrepreneurs" having inspired to customize and popularize his timepiece, they may be similar to the lucky few who brought the modern gadgets to our lives today.
A thin volume doesn't skimp on scientific data and mechanical details, which could satisfy the curiosity if well understood, or affect the story little if not.
Hard core science (Astronomy - mastered and being explored by the privileged elite) lost to the mechanical craft (uneducated "clocksmith") on a practical problem solving, where a creative mind applied.
While calculating latitude had historically come relatively easy to ancient scientists and navigators by measuring the height of the sun and stars, there was no comparatively straightforward way to determine longitude -- bad news for ship captains the world over. As recently as 1714, English Parliament offered a prize to anyone who could devise a method of calculating longitude to within a set degree of accuracy. Clockmaker John Harrison accepted the challenge and proceeded to devote the next four decades of his life to this achievement, despite obstacles placed in his path by England's astronomer royal and the Board of Longitude itself. This slim volume is an interesting history behind a scientific concept that we take for granted today.
A quick and fun read about one man's effort to solve a critical problem through experimentation sand tinkering. His struggle was compounded by the theoretical scientists of his day, because they wanted a beautiful mathematical solution to the problem. Their disdain for machinery and their power over the politicians responsible for awarding contracts made for a social challenge as well as a technical challenge.
The 'Lone Genius' was John Harrison, (1693 - 1776). Dava Sobel's well-written book about him brings the story to life. I read the book in 2012 and the following year I saw his plaque in Westminster Abbey. You can see a photo of it (with the longitude for the stone inscribed on the inlaid steel strip) at the Abbey's website: http://www.westminster-abbey.org/our-history/people/john-harrison

This is the fascinating story of John Harrison, the man who single-handedly and without the benefit of high education, technical antecedents, social standing or public or private patronage, solved the age-old problem of determining longitude -- knowing one's precise position in the East-West direction. His solution was blingingly simple but almost impossibly difficult to execute: designing and constructing a highly accurate seagoing clock. As has been so often the case, a true genius and original thinker, far from being honored and rewarded for his achievements and contribution to mankind (in this case, sailors in particular) he is beset by jealous enemies and abused by the authorities of his day almost to the end of his life. Despite every possible obstacle placed in his way, he succeeds in the end.
This book was an interesting and enjoyable read.
I honestly did not expect to enjoy this book, thinking it would merely be "good for me". What a pleasure to be so wrong! Wonderful, personal writing of a significant story. Bonus : now I understand about longitudes.
A good account of a fascinating story - wish it had been more compelling. I wish it was a novel.
