Around 530 BCE, Pythagoras moved to the Greek colony of Croton in southern Italy, where he established a religious and philosophical school. The Pythagorean Brotherhood, as it was called, was both a scientific community and a religious sect. Members followed strict rules, including a vegetarian diet and a belief in the transmigration of souls (reincarnation).

"Pythagorean Theorem"

The most famous contribution attributed to Pythagoras is the Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Although this theorem was known to the Babylonians long before Pythagoras, he and his followers were the first to provide a formal proof.

"Mathematical Contributions"

Beyond the Pythagorean theorem, Pythagoras and his followers made significant contributions to mathematics, including:

The concept of numerical relationships in music, where they discovered the connection between the length of strings and musical pitch.
The study of proportions and ratios.
The belief that numbers have inherent properties and that the universe can be understood through mathematics.
