The clocks of John Harrison

    For those few of you close to Mystic, CT I would like to mention that the Mystic Seaport Museum has a exhibit on the clocks of John Harrison. It is closing March 28 so there is not too much time left. Here is a link

    Its due to the earth's 24 hour rotation so can't simply find it by looking at the stars unless you know the time.
