Principle:
1. Scientist Galileo saw the chandelier wobble by the wind in the church. Using the method of measuring the pulse beat, he first found that the period of the pendulum was basically unchanged regardless of the swing amplitude.
2. Later mathematicians proved this in theory, and physicist Huygens developed pendulum clocks based on this principle. The electromagnetic swing is like a pendulum, no matter how big the swing is, the period of swing back and forth is basically the same. After switch is on, when the swing becomes larger and larger, you can observe that no matter how big the swing is, Swing back and forth swing the time is basically unchanged. This is the principle of simple pendulum cycle invariance.
