He was born around 580 BC in Samos, Greece. His father’s name was Phytagoras Mnesarchus and his mother’s name was Pythais. He is a mysterious figure. Often, he is described as a pure mathematician, because he is considered an important figure in the development of mathematics. However, his achievements in mathematics are unknown. He also saw the mathematical order in astronomy. He believed that the planets circled the sun at intervals related to the length of the harmonic string. He assumed that the movements of the planets gave birth to a musical sound called “harmony of the sphere”. However, this view is not eternal. In addition, he stated that morning stars and night stars are the same object. Furthermore, the Greeks called the star Aphrodite, while the Romans named it Venus.

Pythagoras is famous for his contributions in the field of geometry. He developed the Pythagorean Theorem, where the length of the square of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. Although the Egyptians had used this theory earlier, it was Pythagoras who understood the difference between an empirical estimate and a strong mathematical proof.

Phytagoras died in 475 BC.
