"In 1714, the British Parliament offered . . . L 20,000 ($12 million in today's currency) to anyone who could solve the problem of how to measure longitude at sea. Sobel recounts clockmaker John Harrison's lifelong struggle to win this prize by developing a timepiece impervious to the pitch and roll ofthe sea. His clock {is} known today as the chronometer."
