The Historical Origin of the World's First Mechanical Tower Clock
The German Peter Henry invented a spring-driven clock in 1500. One day in 1528, 18-year-old Galileo went to the church of Pisa to worship. He accidentally found a bronze lamp hanging on the statue of a deity swinging. And it was found that although the swing amplitude of the chandelier gradually became smaller, the time it took to swing once did not decrease. Therefore, he measured the number of beats of his pulse, and measured the isochronous law of the swing of a single pendulum that the period of the chandelier's swing has nothing to do with the amplitude of the swing.
A few years later, when Huygens read Galileo's paper, he couldn't help but think: "Since the swing of an object is isochronous, then if the force of the swing of the object can be used to drive the gears in the clock to rotate, it will not be possible to get more Is the time accurate?"
Selle põhjal tehti edasine otsus. Ja määrati seos lihtsa pendli vibratsiooni perioodi ja pendli pikkuse ruutjuure vahel. Huygens oli väga elevil ja asus kohe taimeriga katsetama. Ebaõnnestunud, uuesti ebaõnnestunud... Ta töötas väsimatult ja nägi vaeva, et end ära tasuks. Pärast mitmeid katseid konstrueeris Huygens lõpuks pendlimehhanismi, mis asendaks tornikella tasakaaluratta. 1656. aastal tellis ta edu saavutamiseks kellassepa. Et luua kell, mis kasutab aja hoidmiseks pendli vibratsiooni.
