把这一句，留给此刻的你
The only thing that might have annoyed some mathematicians was the presumption of assuming that maybe the axiom of choice could fail, and that we should look into contrary assumptions.
唯一可能惹恼一些数学家的是这样一种假设，即选择公理可能会失败，而我们应该研究相反的假设。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
The good life is one inspired by love and guided by knowledge.
美好的生活是由爱所激励，由知识所引导。
That is the best part of beauty, which a picture cannot express.
这就是美最好的部分，是一幅画无法表达的。
If you don't make things happen then things will happen to you.
如果你不让事情发生，那么事情就会发生在你身上。
