I'm a little disappointed that an article about our understanding of time across history didn't include the marine chronometer. It was a major breakthrough for nautical navigation in the 1700s. It allowed precise longitude determination long before GPS. Prior to the marine chronometer latitude could be precisely determined with celestial navigation, but longitudinal skew due to earth's rotation could not be compensated for without precise timekeeping. https://en.m.wikipedia.org/wiki/Marine_chronometer |
