Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.

Every soul needs rest and relaxation.

Sometimes you just have to pick yourself up and carry on.

The greatest enemy of a good plan is the dream of a perfect plan.

写作就是抵抗遗忘。

我唯一能依靠的就是我自己的不确定性。

一本优秀的传记是过去与现在之间的桥梁。
