**Pythagoras**

Pythagoras was born in approximately 569 B.C. His father was Mnesarchus and his mother was Pythais. Pythagoras spent his early years in Samos. There is little known about his child hood and all physical descriptions of Pythagoras are said to be fictitious except for the vivid birthmark on his thigh. It is believed that he had two brothers and some believe there were three.

Pythagoras was extremely well educated. There were three philosophers that influenced him while he was young. One of the most important of these man was a man named Pherekydes. The philosopher that introduced Pythagoras to mathematical ideas was Thales , who lived in Miletus. It was because of Thales that Pythagoras became interested in math, astronomy and cosmology.

Pythagoras was interested in all principles of mathematics. He was intrigued by the concept of numbers and basically numbers themselves. Pythagoras had a theory that all relations were able to be reduced in to some form of number. Pythagoras also derived a theory on ratios and scales being produced with the sound of vibrating strings. He made large contributions to music theory.

He studied many different types of numbers ,for example triangles, odd numbers and perfect squares. He believed that each number had its own personality traits and were all different and unique. For example ten is the best number because it contains four consecutive integers (1+2+3+4=10)

Pythagoras’ greatest contribution to the mathematical society of today is
Pythagoras theorem. It is believed that the theory of a^{2}+b^{2}=c^{2}
was known to the Babylonians 1000 years before Pythagoras but it was he who was
able to prove it.

**The following are a list of theorems contributed by Pythagoras**

1.The sum of the angle is a triangles equal to two right angles.

2.The Pythagorean theorem

3.Construction figures of a given area and geometrical algebra.

4.The discovery of irrationals

5.The five regular solids.

6. Pythagoras taught that the earth was a sphere in the center of the universe.

Pythagoras life came to and end in approximately 475 B.C. Many of his contributions are still used in everyday math of today's generation.
