Pythagoras (c.582-c.507 BC)
Pythagoras was a Greek philosopher from Samos who founded the Pythagorean School in Crotona. Not much is known of his actual findings because all his students attributed all their work to Pythagoras whom they ranked among the gods. His school became somewhat of a secret society and was extremely exclusive. Pythagoras and his students are best known for transmigration of souls and the theory that numbers constitute all things in nature. Transmigration of souls is the belief that one soul passes from one entity to another (also known as reincarnation). Pythagoras believed everything could be expressed as numbers. Pythagoras and his followers were revolutionary thinkers of the time. The word “philosophy” was first attributed to Pythagoras. He made many advancements in the fields of mathematics, geometry, astronomy and medicine. He was one of the first to teach that the world is spherical in shape.
Pythagorus is commonly known for his Pythagorean theorem which finds the hypotenuse of a right triangle.
He also recognized the numerical relationships of revolution in the planets, sun and stars. He called these relationships the music of the spheres. Keplar would use this same principle to formulate his model for the solar system.
