The Pythagorean theorem is the most demonstrated theorem. It has been demonstrated over 350 times. Pythagoras was not only a mathematician, he was also a musician and a philosopher. But he was a bit of a peculiar philosopher because he studied philosophy by means of mathematics. Thanks to this, he was able to demonstrate the famous Pythagorean theorem .
Pythagoras founded a brotherhood where study philosophy by mathematics.
This philosopher was also important because he found the musical scale by mathematics.
This research project is based on Pythagoras's philosophy and my practical part consists of explaining his demonstrations that I can understand. Finally, I would say that I couldn't do this project without four really important books of Pythagoras's philosophy.
