Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time

In 1714, the English Parliament announced a staggering reward to anyone who could present a successful method of measuring longitude at sea and therefore prevent thousands of deaths from shipwreck and disease.  Most applicants for the reward looked to astronomy, so the committee charged with ascertaining a winner was surprised to receive John Harrison's solution.  Harrison, an unknown clock-maker, claimed to have invented a maritime clock that would function better than the fickle clocks of the age, which often lost whole hours in short spans of time.  Longitude details Harrison's life-long quest to perfect his invention and receive recognition for his work.

“Time is to clock as mind is to brain. The clock or watch somehow contains the time. And yet time refuses to be bottled up like a genie stuffed in a lamp.”
