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."

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. 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.

Review of 'Longitude' on 'Goodreads'

4 stars

Short, crisp, and quite enjoyable history of the longitude problem. As a help to understand the mechanical devices described in this book, I looked at videos and animations of Harrison's chronometers available online. That helped a lot in understanding the scale of achievement of John Harrison. The author does not attempt to make a "what happened at the end?" mystery out of this story. The summary of what happened is stated right at the beginning. The author instead engages the reader by providing the context of the times, the details of the challenges, and so on. This approach works quite well.
Those of you who work in engineering will find the technology development challenges described in this book quite relatable!
