当天赋不努力时，努力会战胜天赋。

I don't fear failure. I fear not trying.

计算复杂性的美在于它能够揭示问题的固有难度，而不管用于解决这些问题的具体算法是什么。

I'm not afraid to fail. I'm not afraid to fall. I'm not afraid to be embarrassed. I'm not afraid to be vulnerable.

译文：聪明用错地方了，不如一辈子愚钝；交友不慎，错交朋友，还不如静下心来读书。赏析：聪明反被聪明误，聪明的才智用在正道，才能凸显它的价值，反之则会贻害无穷。朋友在于精，不在于多，狐朋狗友千千万，不如知己一人。

海洋有其风暴和平静，有其漩涡和洋流。

I believe that science has great potential to improve human life.

To solve a mathematical problem is to uncover a piece of the universal puzzle.
