Galileo Galilei was born in Pisa,on February 15,1564.He was an outstanding Italian scientist who made significant contributions to astronomy, physics, engineering, and mathematics. Galileo made significant contributions to the scientific method, emphasizing the importance of experimentation, observation, and mathematical analysis in understanding the natural world. His work laid the foundation for the modern scientific approach.

Galileo’s support for heliocentrism and his defiance of the Church’s geocentric doctrine led to his trial by the Roman Inquisition in 1633. He was forced to recant his views under threat of torture and spent the rest of his life under house arrest. Despite this persecution, Galileo’s ideas continued to influence scientific thought, and his work remains foundational to our understanding of the universe. He died on January 8, 1642, in Arcetri, Italy.
