数学之美不在于其复杂性，而在于其简洁性以及它揭示的关于宇宙的深刻真理。
The beauty of mathematics is not in its complexity, but in its simplicity and the profound truths it reveals about the universe.
The world is before you and you need not take it or leave it as it was when you came in.
There is only one good, which is knowledge, and one evil, which is ignorance.
