Longitude

The story of mariners' centuries-long search for ways of determining longitude that tells not only of the scientific advances but of the perseverance, pettiness, politics, & interesting anecdotes involved. Longitude is the dramatic human story of an epic scientific quest, and of John Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, brilliance and the absurd, it is also a fascinating brief history of astronomy, navigation, and clockmaking. Through Dava Sobel's consummate skill, Longitude will open a new window on our world for all who read it.
