Galileo Galilei

Galileo Galilei was born in Pisa, Italy on February 15, 1564. In 1572, he and his family moved to Florence began to study medicine at the University of Pisa. He never finished degree because he left to study math with Ostilio Ricci. In 1600, he met Marina Gamba and had his first daughter, Virgina. They also had a daughter named Livia, born in 1601 and a son named Vincenzo, born in 1606. Galileo began to question Aristootle's teachings. Galileo Galilei first tested to see if and object the same size and shape, but different weight would fall at different speeds. He had two objects and dropped them off the leaning Tower of Pisa. They fell at the same rate, which means that Aristotle was incorrect because he claimed that the heavier object would hit the ground sooner. In 1610, Galileo began to work with the telescope. Hans Lippershey invented the telescope, but Galileo focused it into the stars. Using the telescope, he discovered the craters on the moon, four of Jupiter's mooons, and the rings of Saturn. He was also able to defend Nicolaus Copernicus' theorey of how the Earth and other planets revolved around the Sun. The church taught that the Sun and planets all revolved around the Earth. He went against the Holy Office of the Inquisition for defending the Coprnican doctrine. He was later sentenced to permanant house arrest for publishing his book Dialogue Concerning the Two Chief World Systems.

Galileo improved it to be able to see stars and planets. Using the telescope, Galileo was able to agree with solid evidence the Copernican doctrine.
