The story of scientists' exploration (about 100 words)

Galileo, a famous Italian physicist and astronomer, was a diligent thinker. Galileo was a Catholic. One day, he went to the church in Pisa. Suddenly, a gust of wind blew, making the chandelier swing in mid-air. At this time, Galileo discovered that no matter how big or small the chandeliers are, they are always the same length. Another gust of wind blew, and Galileo was surprised to find that the swing of the chandelier had nothing to do with the swing amplitude. Galileo went home to find a rope, hung a heavy object, changed the way and made it swing. So, he once again found that the time of a swing has nothing to do with the weight of the object, but with the length of the swing.
