——《我的回忆》（1911年11月中旬）
"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors."
【译文】水过分清澈就不会有鱼，人过于明察就不会有人为你出主意。世上的聪明人若减少一半，那么愚笨的人也就没有了。
The most common form of despair is not being who you are.
"Hope is a fragile thing, but it is also the most powerful force we have."
音乐是灵魂隐藏的算术练习，它不知道自己正在与数字打交道。
The more we learn about black holes, the more we realize how much we still don’t know.
