Galileo Galilei

Galileo Galilei was born in 1564 in Pisa, Italy. As a student, he initially studied medicine, but eventually switched to math and philosophy. After he finished his schooling, he taught math at different universities for 21 years. While teaching, he worked on many different theories regarding mechanics and pendulums. After hearing about the invention of the telescope in 1609, Galileo built a better version and made many discoveries about astronomy, most notably the four largest moons on Jupiter. Galileo was outspoken in his support for the Copernican Theory, the theory that said the planets orbit the sun, which was contrary to popular belief at the time. He was tried for heresy in 1614 for his support of this theory and was eventually banned by his church from further teaching the theory. In 1632, he was tried again for heresy for a controversial book he published and was sentenced to permanent house arrest, and he died 10 years later on January 8, 1642.
