Philolaus

Philolaus (ca. 480 BC – ca. 385 BC, Greek: Φιλόλαος) was a Greek Pythagorean and Presocratic. He argued that all matter is composed of limited and unlimited things, and that the universe is determined by numbers. He is credited with originating the theory that the earth was not the center of the universe.
