Pythagoras

c.

550-480 B.C.

Greek philosopher and mathematician who founded a philosophical and religious movement based on the belief that all natural systems are determined by mystical numerical relationships. He and his followers established the close relationship between science and mathematics and strongly influenced Plato. The Pythagoreans attempted to apply their principles to all areas of the natural world; it has been suggested that they may have written the Hippocratic Oath.
