Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost.
A journey is a person in itself; no two are alike. And all plans, safeguards, policing, and coercion are fruitless. We find after years of struggle that we do not take a trip; a trip takes us.
The best way to find out if you can trust somebody is to trust them.
"To travel is to live."
你的手干不了活是因为我。
解决复杂问题的关键在于将它们分解成更简单的问题。
不论这个世界如何打击我,在我内心,总有更强大、更好的东西在反击。
