Résumé
Sobel describes the work of John Harrison, a London clockmaker, who invented the chronometer. For centuries there was no accurate way to determine longitude, so in 1714 the British parliament offered twenty thousand pounds for a solution. While others looked… for a celestial answer, Harrison worked almost forty years on a mechanical one. 1995.
