Plato (427 BC-347 BC) was a very knowledgeable person in Greece. He wanted to engage in political activities in his early years, but Plato was disheartened by the execution of Socrates, a philosopher he believed in (June 399 BC). He has received a good education since childhood and is versatile.

In 387 BC, he founded Agademi Academy (Plato Academy) in the garden commemorating the legendary hero of Athens, Agal Hume. This is the first comprehensive higher education school in the west to impart knowledge and research academics. The training object of the college is the children of slave owners and nobles. It integrates imparting knowledge, academic research, political consultation and training scholars and political talents. College students don't pay tuition fees, and the answer must have elementary knowledge of mathematics and physics, and men and women are treated equally. Education is rich in content, including philosophy, natural science, humanities, arithmetic, geometry, astronomy, music theory, grammar, law, history and morality, and physical education is listed as a compulsory course. The college attaches great importance to mathematics, especially geometry. It is said that there is a sign hanging at the entrance of the academy, which says "non-geometricians are not allowed to enter", and some people say that the sign says "those who don't know geometry are not allowed to enter" In short, geometry is the main research content of this school.
