The Pythagoreans

The Pythagoreans were an ancient Greek philosophical and mathematical group who believed that numbers and ratios underpin the universe. They are best known for discovering the Pythagorean theorem, which relates the lengths of a right triangle’s sides. They also saw numbers as the fundamental structure of reality, with concepts like harmony, proportion, and order reflecting the mathematical beauty they observed in nature and music. Their ideas influenced both mathematics and philosophy, emphasizing that understanding numerical relationships can reveal deeper truths about the universe’s underlying harmony.
