量子引力问题不仅是物理学的问题，也是科学哲学的问题。

I think the only way to conquer fear is to tell it to go to hell.

我们都受到自己天性的束缚。

Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.

译文：求全责备之心，可以用在自我的修身养性上，不能用在待人接物上；知足常乐的心态，可以用在各种处境的时候，不能用在读书学习上。赏析：严以律己，宽以待人，是做人的根本，是远离祸患的根本。读书学习，我们不能安于现状，要有进取精神。在为人处世时，我们索取无度，贪得无厌，就会自食恶果。
