Why should Pythagoras be so important?

Pythagoras is important primarily for his contributions to mathematics, particularly the Pythagorean theorem, which establishes a fundamental relationship between the sides of a right triangle. This theorem is foundational in geometry and has applications in various fields, including physics, engineering, and computer science. Additionally, Pythagoras' ideas extended beyond mathematics to influence philosophy, Music Theory, and the concept of number mysticism, making him a pivotal figure in the history of Western thought. His emphasis on the interconnectedness of numbers and the universe laid the groundwork for later mathematical and scientific developments.
