In the early days, it was used for the main church of the Renaissance. It was completely mechanical, powered by heavy hammers, and the clock was completely used to collide the bell for the clock. Therefore, at that time, the construction and mechanical system of a tower clock were very complicated. . On one day in 1528, 18-year-old Galileo went to the church of Pisa to worship. He inadvertently saw a bronze lamp hanging on a Buddha statue shaking. I saw that although the intensity of the chandelier's shaking was gradually reduced, the time used for one shaking was not reduced. Therefore, he calculated by the frequency of his own pulse rate, and measured the isochronous law of single pendulum shaking that the chandelier shaking cycle time is irrelevant to the shaking strength. So, if we can use the falling force of the object to drive the gears in the clock to rotate, can we not get a more accurate time? After a series of experiments, Huygens finally designed a pendulum mechanism to replace the tower clock In 1656, he commissioned a clockmaker to successfully create a tower clock that uses the vibration of the pendulum to time the clock.
