Summary

Greek philosopher and mathematician — founder of the Pythagorean school — who identified the mathematical relationships in musical harmonics and whose theorem relating triangle sides is the most famous result in mathematics — whose beliefs about the soul's immortality influenced Plato.

Core Contribution

Creates the mathematical description of harmony — Pythagoras's discovery that musical intervals correspond to simple mathematical ratios (octave = 2:1, fifth = 3:2) was the first discovery that mathematics governs natural phenomena and made him the founder of mathematical physics and the belief that the universe has a mathematical structure.
