... Galileo came up with the idea of inertia, which was a huge jump from the ideas of Aristotle. Aristotle was very logical and did a systematic study of nature. He thought that the earth didn't move. That makes common sense. He thought that rocks fell down because they're made of earth, and smoke went ...
