Two examples of the main ideas of the Renaissance were Rebirth and Rediscovery. Galileo Galilei was one of the most important people during the renaissance, due to his research into astronomy, physiscs, and engineering. Considered the "Father of Modern Science", Galileo is most well known for his discovery of the largest four of Jupiter's moons. He also was one of the driving forces behind the popularization of the idea of heliocentrism.
