Since the days of transoceanic voyages, determining the exact location of a vessel at sea was of paramount importance. Determining the precise longitude of a ship at sea was one of the most sought after practical solutions for accurately navigating the earth’s oceans. For centuries, some of the brightest scientific minds have pondered over finding a realistic method for measuring the exact longitude of a ship on voyage, without much luck.

In this review of the book titled ‘Longitude’ – written by Dava Sobel – we find the story of John Harrison, an English carpenter and clockmaker who invented the marine chronometer, which allowed mankind to solve the problem of calculating longitude while at sea.
