Pythagoras was born sometime between 495 and 575 B.C. on the island of Samos. There are few documents recording his life therefore little is known about what he did in his life but there are records of things he discovered and studied. All the descriptions that have been recorded about Pythagoras' appearance are most probably made up or embellished, although it is believe that he did have a striking birthmark on his thigh. It is believed that he had two brothers, but some sources say he had three. For many years he lived in Kronton, which is located in Southern Italy. He established a school of philosophy and science there and gained followers and together they came to political power. Both men and women were permitted to join, but were all sworn to secrecy. This secrecy caused the group to be surrounded by suspicion. A group of Pythagorean rivals fought back against them and practically shattered the organization. There are also rumors that Pythagoras traveled to Egypt and Babylon at one time but there is no proof of this. He is said to have adopted customs from Egyptian priests such as abstaining from eating beans, not wearing animal skin clothing, and trying to remain very pure. He died in the early part of the 5th
Pythagoras is known as the first pure mathematician. Mathematically he believed that all things in the universe are numbers. Along with this he believed that numbers gave shape and form to all matter. Pythagoras never intend to solve problems and equations or discover things; he was only interested in the concept of numbers and triangles and abstract proofs. He is probably most famous for the Pythagorean theorem, which states that the hypotenuse of a right triangle equals the sum of the squares of the other two sides. The theorem was actually first discovered by the Egyptians but Pythagoras was the first to actually prove why it was true mathematically. There are several other proofs that are credited to Pythagoras and the Pythagoreans. They discovered that a polygon with n sides has a sum of interior angles which equals 2n-4 and that the sum of the exterior angles equals three hundred and sixty degrees. Pythagoras is also attributed to discovering irrational numbers although many people feel this is not true because it goes against his belief that everything in the universe is made up of numbers. He felt that ten was the greatest number because it is the sum of the first four integers. Pythagoras was very interested in odd and even n
