This book considers the problem of longitude from a number of viewpoints. While Dava Sobel's book concentrated on the Harrison/Maskelyne controversy, this volume uses historical, mathematical and geographic viewpoints. What is impressive is the genius, dedication and tenacity of the Renaissance scientists. They may not have had GPS but they knew what they were doing.

This review is top notch and comprehensive. It's the book of choice to cover the background and the technology. I'm not a watch or clock fanatic, but I slam dunked this whole book in just a couple days; a 15 hour Qantas flight kept me captive. I wish there was more discussion on the nature of astronomy and how the clocks were calibrated. I want to read up on octants, sextants and basic navigation now. This book deserves five stars. The A&E four hour documentary, "Longitude", this month also deserves high marks. If someone knows of a good read on navigating with astronomy that's more layman oriented, please email me (thanks).

This beautifully presented large hardback is actually a series of essays covering the story of the search for Longitude from the 16th century to the 19th. The essays deal with a range of subjects from the mathematical to the absurd, from astronomy to cartography and has 4 excellent appendices. The book is well laid out with both black&white and color photography in a manner that means you don't need to be a student of the sea of chronology to understand it. A good book to have on the shelf.

Excellent book focused on the Longitude act's of the 1700's. The primary emphasis is on the two technologies Lunar-distance and chonometer for determining longitude with a precision under 1 degree. The relative percentages are: 50% chonometer, 30% lunar distance, 10% Jupiter's moons, 10% general history pre-1600's. I gave it four stars instead of 5 because I thought the book was going to be a balanced discussion ( i.e. equal time)encompassing all methods of determining longitude irrespective of a 1 degree precision. All that said, I would still recommend the book to anyone interested in the topic.
