Galileo Galilei Trivia – Father of Modern Science

Galileo Galilei was born in Pisa in 1564. He studied motion, pendulums and falling objects, insisting on experiments and mathematics rather than relying only on ancient authorities.

In 1609 he built improved telescopes and discovered Jupiter's moons, mountains on the Moon, sunspots and the phases of Venus. These discoveries supported Copernicus's idea that Earth orbits the Sun.

His views brought him into conflict with the Church. In 1633 he was tried and placed under house arrest, but he continued working, publishing Two New Sciences in 1638. He is often called the father of modern science.
