Pythagoras was a philosopher whose ideas still influence mathematics today. He founded Pythagoreanism in southern Italy and helped people improve their minds in Croton. Born around 585 BC on Samos, Pythagoras did not write his ideas down; most information comes from writers like Plato. He traveled to Egypt and Crete before settling in Croton, where he taught about 300 students. Pythagoras believed numbers were essential. The Pythagorean Theorem, a² = b² + c², shows how the sides of a right triangle relate. He also created the Pythagorean Cup, which promotes moderation in drinking wine. His teachings continue to be important today. https://www.ancient-origins.net/history-famous-people/pythagoras-one-greatest-minds-his-time-007169
