Longitude

This film tells the story about John Harrison, a clockmaker and artisan in the 18th century, who was the first to develop a method for accurately finding longitude at sea. This film provides a historic view of how difficult it was to measure longitude, and how valuable this information was. This was also the first example of the use of highly accurate clocks to measure position on earth. Extremely precise and accurate clocks are still used for mapping the earth today.
