Harrison's clocks revolutionized global navigation from "summary" of Longitude by Dava Sobel
For centuries, mariners struggled to accurately determine their longitude at sea, often resulting in disastrous consequences. The quest for a reliable method to measure longitude was a pressing concern for nations with seafaring interests. The British Parliament offered a substantial reward for anyone who could devise a practical solution to this problem. It was John Harrison, an English clockmaker, who rose to the challenge and forever changed the course of navigation. Harrison dedicated his life to creating a timepiece that could withstand the harsh conditions of the open sea while maintaining precision. His clocks, known as marine chronometers, were a remarkable feat of engineering and craftsmanship. Unlike previous methods that relied on celestial observations or complex mathematical calculations, Harrison's chronometers provided a simple and accurate way to determine longitude. By comparing the time displayed by the chronometer with the local time at a known reference point, such as Greenwich, sailors could calculate their position with unprecedented a...
