Longitude - why time is one of the most important attributes of our world - the Awesome World of Things
Longitude a geographic coordinate that specifies the east-west position of a point on the Earth's surface and is best determined using time measurements. Galileo Galilei proposed that with accurate knowledge of the orbits of the moons of Jupiter one could use their positions as a universal clock to determine of longitude, but this was practically difficult especially at sea. An English clockmaker, John Harrison, invented the marine chronometer, helping solve the problem of accurately establishing longitude at sea, thus revolutionising safe long distance travel.
