By Dava Sobel
Learn about John Harrison, an English clockmaker, who solved the Longitude
Problem by developing a clock that would keep precise time at sea. With
that clock, sailors could know what time it was on board and at home when
a single event took place on board (i.e. when the sun reached its highest
point in the sky). And by knowing the difference in hours and minutes
between the two times, they could then calculate their longitude.(More) |
