Dava Sobel's Longitude tells the story of how 18th-century scientist and clockmaker William Harrison solved one of the most perplexing problems of history--determining east-west location at sea. 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. --Therese Littleton
From Library Journal
Sobel's 1995 volume attracted a large audience, an unusual feat for a historical science title. Her text describes John Harrison's development of the chronometer, an instrument that measured time exactly while at sea and allowed mariners to calculate longitude for the first time and accurately navigate. This handsome edition is profusely illustrated with numerous annotated photos and paintings of the players and the machinery that led to the chronometer's creation.
