"Experiment on the Leaning Tower" PPT courseware 4

Galileo Galilei (1564~1642), a great Italian physicist and astronomer, a pioneer of the scientific revolution. The first person to use telescopes to observe celestial bodies and achieve a lot of results, the founder of modern experimental science, and is known as the "Father of Modern Science". Engels called him "one of the giants who was able to break old theories and create new ones regardless of obstacles."

The Leaning Tower of Pisa is in the ancient city of Pisa in western Italy. Founded in 1173. The tower has a total of 8 floors and is 54.5 meters high. When the tower reached the third floor, it was discovered that the foundation began to tilt. When the entire tower was completed, the centerline of the tower top had deviated from the vertical centerline of the tower by about 2 meters. Because the tower "slants but does not collapse", it is famous. In 1590, Galileo performed a free fall experiment on the tower, making the Leaning Tower of Pisa even more famous.
