On this Theme Thursday, we explore Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientifist Problem of His Time. Though focusing on a male contribution to scientific knowledge, Dava Sobel is an New York Times author and American writer of popular expositions of scientific topics. She was presented with the Klumpke-Roberts Award for outstanding contributions to public understanding and appreciation of astronomy in 2008. In 2006, she was the Robert Vare Nonfiction Writer-in-Residence at the University of Chicago. She received the 2001 Public Service Award of the National Science Board for fostering public awareness of science.
From Amazon, “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. The scientific establishment of Europe-from Galileo to Sir Isaac Newton-had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, 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.”
