Galileo Galilei (scientist)

Galileo Galilei was an Italian scientist and mathematician from the 16th and 17th centuries, often called the father of modern science. He made groundbreaking discoveries using the telescope, such as moons around Jupiter and phases of Venus, which supported the Copernican model that Earth orbits the Sun. Galileo emphasized careful experimentation and observation, helping to shift science from relying on tradition to evidence-based understanding. His work laid the foundation for physics and astronomy, influencing how we understand motion, gravity, and the universe today.
