The art of longitude
Ethan Zuckerman posted “Clifford Ross is trying to find the longitude” today, a fascinating story of invention, time, and the art of longitude:
Clifford Ross is an artist who has found himself becoming an inventor. His talk, “Finding the Latitude - The Art of Invention, the Invention of Art”, begins with the history of the naval chronometer. Ross tells us his hero was John Harrison, who won the 20,000 pound ($20 million in current dollars) prize offered by King Charles the II in the 1714 Longitude Act.

Finding Time
Harrison was an uneducated carpenter who lived ourside of London. He built a grandfather clock entirely our of wood - for fun - in 1718, and took on the challege of the shipboard chronometer in 1730, completing his first clock - commonly called H1 - in 1735. It was an immense technical challenge - a clock that could keep time accurately on a moving ship, through extremes of temperature and humidity.
And this precious tidbit:
Ross notes that “finding the Longitude” became a catchphrase for the pursuits of fools and lunatics.
