Anyone alive within the eighteeth century might have recognized that "the logitude problem" was once the thorniest medical obstacle of the day--and were for hundreds of years. missing the facility to degree their longitude, sailors in the course of the nice a while of exploration have been actually misplaced at sea once they overpassed land. hundreds of thousands of lives, and the expanding fortunes of countries, held on a resolution.
The clinical institution of Europe--from Galileo to Sir Issac Newton--had mapped the heavens in either hemispheres in its definite pursuit of a celestial solution. In stark distinction, one guy, John Harrison, dared to visualize a mechanical solution--a clock that will hold percise time at sea, anything no clock had ever been capable of do on land.
