Pythagoras
One of the most famous names in the history of mathematics is Pythagoras. He is recognised as the first true mathematician. Pythagoras made influential contributions to philosophy and religion in the late 6th century BC. He is often revered as a great mathematician, mystic and scientist and is best known for the Pythagorean Theorem which bears his name.
Early Life: He was born on the Greek Island – Samos in the eastern Aegean. His birth date is estimated to be somewhere in 570 BC. His father was a merchant and travelled a lot for business. Pythagoras also accompanied his father in various expeditions.
Inspiration: When Pythagoras was 18, he met Thales - the first known Greek philosopher and scientist. It was this meeting which triggered his interest in the science of mathematics and astronomy. Thales advised him to travel to Egypt and explore these avenues. Pythagoras spent years in Egypt in search of all available knowledge and received wisdom from an Egyptian priest Oenuphis of Heliopolis.
Mathematikoi: In around 530 BC, Pythagoras settled in Croton- Italy, where he founded a philosophical and religious school that instantly attracted many followers. He established and headed a society called Mathematikoi. The members of his society lived permanently together and followed strict rules. Pythagoras taught all the members of the society personally.
Pythagorean Theorem: Pythagoras has commonly been credited for discovering the Pythagorean Theorem of geometry. It is widely believed that Pythagoras or his students were the first to construct its proof. Pythagoras believed that numbers had personalities like perfect or incomplete, masculine or feminine, beautiful or ugly. He also studied properties of numbers which would be familiar to mathematicians today like even and odd numbers.
Later years: Pythagoras desired to stay out of politics, yet his society was always affected by politics. In 510 BC Croton attacked and defeated its neighbour Sybaris and there are certainly some suggestions that Pythagoras became involved in the dispute. Then in around 508 BC the Pythagorean Society at Croton was attacked by Cylon, a noble from Croton itself. Pythagoras escaped to Metapontium and the most authors say he died there. His society expended rapidly after 500 BC and its contributions to mathematics are still recognised and respected.
