在物理学中，我们经常发现最美丽的解决方案来自于最混乱的问题。
In physics, we often find that the most beautiful solutions emerge from the messiest problems.
You are too generous to trifle with me. If your feelings are still what they were last April, tell me so at once. My affections and wishes are unchanged, but one word from you will silence me on this subject for ever.
You forget what you want to remember, and you remember what you want to forget.
不要让任何人告诉你你做不到。证明他们是错的。
The light of truth never goes out.
