The beauty of mathematics lies in its ability to describe the universe in the most elegant way possible.

我从十五岁开始致力于学习，三十岁便能自立于社会了，四十岁对各种事理不再迷惑不解，五十岁懂得了自然界的规律，六十岁对听到的事情能领会贯通，并能辨别是非真伪，七十岁时做事能随心所欲，但又不会超出礼法的规范。

她那时候还太年轻,不知道所有命运赠予的礼物,早已在暗中标好了价格。

"Formal methods are not a silver bullet, but they are an essential tool in the quest for reliable systems."

你输得越多，学到的就越多。
