Pythagoras was a Greek philosopher who lived between 580-520 B.C. He founded a philosophical and religious school in Croton, which made outstanding contributions to the field of mathematics. Pythagoras and his cult members believed that everything was related to mathematics and agreed that, ultimately, "all is number".
Pythagoras is also famous for his study of acoustics and his theorem relating the lengths of the sides of a right triangle, which confirmed the existence of irrational numbers.
