A mathematician's work is never done; there are always new questions to ask and new mysteries to solve.
若我遇你,经年之后,我该如何贺你,以眼泪,以沉默。
The truth is rarely pure and never simple.
The more you accomplish, the more you want to accomplish.
写作是一种自我发现的过程,每一次写作都是一次心灵的旅程。
The beauty of mathematics lies in its ability to connect seemingly unrelated ideas.
