Introduction to the Leaning Tower of Pisa

The Leaning Tower of Pisa is located in the Church Square in the ancient city of Pisa in central Italy. It is a bell tower in a group of ancient Roman buildings. Construction of the Leaning Tower of Pisa started on August 9, 1173, and took two centuries to complete. When the third floor was being built in 1178, the tower began to tilt, and construction stopped for a century. In 1272, architects built a fourth floor with an offset center of gravity to compensate for the tilt of the tower. In 1301, construction of the Leaning Tower of Pisa was stopped again. It was not until 1372 that the construction was completed and a bell was placed on the top of the tower.

Galileo Galilei (1564-1642)

Galileo Galilei was a great Italian physicist and astronomer, a pioneer of the scientific revolution. Historically, he was the first to integrate mathematics, physics and astronomy based on scientific experiments, expanding, deepening and changing mankind's understanding of material movement and the universe. In order to confirm and spread the heliocentric theory of N. Copernicus, Galileo devoted his whole life. As a result, he was persecuted by the church in his later years and imprisoned for life. With his systematic experiments and observations, he overturned the purely speculative traditional view of nature represented by Aristotle, and created modern science with a strict logical system based on experimental facts. Therefore, he is called the "Father of Modern Science". His work laid the foundation for the establishment of I. Newton's theoretical system.
