Mathematics is not a deductive science—that's a cliché. When you try to prove a theorem, you don't just list the hypotheses and then start to reason. What you do is trial and error, experimentation, guesswork.

释义：提醒人们警惕被权力篡改的“官方叙事”。

When words leave off, music begins.

译文：坚贞的操守与日月一样高悬于天，独特的香花随着千山万壑传播到远方。赏析：我们要把自身的德行和操守像香花一样传遍世间，不做违背道德和法律的事情。
