Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
数学不仅仅是关于数字、方程、计算或算法：它是关于理解的。
Anon, who wrote so many poems without signing them, was often a woman.
生命中最美好的不是事物，而是那些瞬间。
直到故事发生了最坏的转折，它才算结束。
每个人都像月亮，有着从来不让任何人看见的黑暗面。
The most dangerous thing is to do nothing.
That’s one small step for a man, a giant leap for mankind.
