Next message: george huxtable: "Re: Timing Lunars with a Rock"
This morning I posted a note saying the old nav. manuals recommended using a
string-and-bullet pendulum to check the half-minute glass. I finished with the
unthinking remark: " I suppose you had to give the pendulum a few moments to
settle the length of its swing."
That's nonsense, of course. I think it's true for clock pendulums, where the
pendulum gets a push. But It seems to me a simple string-and-weight pendulum
would swing a shorter distance each beat, while the time of each swing would
remain the same.
