① Mathematics
Pythagoras' most famous achievement is to prove the right triangle theorem. This is of course just a shining example. What is important is that he initiated the era of generalizing conclusions from mathematical logic thinking, which made a great leap in human thinking.
② Music
Pythagoras was the inventor of the balance. Specifically, Beecher's music theory points out that when the string length is reduced by one third, the scale is five degrees higher; The chord length is halved and the scale is octave higher. It is said that he was inspired by scales when he heard the high notes and low notes coming from the blacksmith's shop while the iron was being struck.
③ Philosophy
It is said that Pythagoras was the first person to use the term "philosopher". He emphasized the importance of social justice. In fact, Bishop is the pioneer of moral philosophy, much earlier than the famous moral philosopher Socrates.
2. Personal profile
Pythagoras (about 580 ~ 500 BC) was an ancient Greek mathematician and philosopher. Pythagoras was born in a noble family on Samos Island (an island in eastern Greece today) in the Aegean Sea. He was smart and studious since childhood, and studied geometry, natural science and philosophy with famous teachers. Later, because of longing for the wisdom of the East, he traveled to Babylon and India, two ancient civilizations with high cultural level in the world at that time, and Egypt (controversial), and absorbed the culture of Arab civilization and Indian civilization (480 BC). Later, he went to southern Italy to teach mathematics and publicize his philosophical thoughts. Later, he and his followers formed a political and religious group called Pythagoras School.
