Galileo and The Lamps (4)
By experimenting in various ways Galileo at last discovered how to attach pendulums to timepieces as we have them now. Thus, to the swinging lamps in the cathedral, and to Galileo's habit of thinking and inquiring, the world owes one of the commonest and most useful of inventions, the pendulum clock.

You can make a pendulum for yourself with a cord and a weight of any kind. You can experiment with it if you wish, and perhaps you can find out how long a pendulum must be to vibrate once in two seconds.
