What is Galileo's introduction?
Galileo galilei (1564 February 15- 1642 October 8th), an Italian physicist, mathematician, astronomer and philosopher, was an important figure in the scientific revolution. His achievements include improving the telescope and its astronomical observation, and supporting Copernicus' Heliocentrism.

Galileo's experiment proved that the object that feels gravity does not move at a uniform speed, but accelerates; As long as the object is not affected by external forces, it will keep its original static state or uniform motion state unchanged. His work laid the foundation for Newton's theoretical system.

Galileo was the first scientist to introduce experiments into mechanics. He determined some important mechanical laws through the combination of experiment and mathematics. 1582, after long-term experimental observation and mathematical calculation, he got the isochronous law of pendulum, and then dropped out of school at 1585 because of family financial difficulties. When he left the University of Pisa, he deeply studied the works of ancient Greek scholars Euclid and Archimedes.

He wrote his first paper entitled "Balance" based on the principle of lever and buoyancy. Soon after, he wrote a paper on gravity, which revealed the essence of gravity and center of gravity for the first time and gave an accurate mathematical expression, so he became famous at one fell swoop. At the same time, he questioned many viewpoints of Aristotle.
