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.
数学不是一门演绎科学——那是陈词滥调。当你试图证明一个定理时，你不仅仅是列出假设然后开始推理。你所做的是反复试验、实验和猜测。
Language is not innocent. It carries the weight of history and power.
机会总是留给有准备的人。
空容器发出的声音最大。
正是在我们最黑暗的时刻，我们必须集中精力看到光明。
