数学研究是一次进入未知的旅程，每一次发现都为新的谜题打开了大门。
The study of mathematics is a journey into the unknown, where each discovery opens the door to new mysteries.

做出伟大工作的唯一方法就是热爱你所做的事情。
With a library you are free, not confined by temporary political climates. It is the most democratic of institutions because no one - but no one at all - can tell you what to read and when and how.
