质量不是一种技术，而是一种哲学。

过去是一个陌生的国度；那里的人们做事方式不同。

Complexity is not just about the number of components in a system, but about the nature of their interactions.

There is no such thing as a quality problem.

The Milky Way’s black hole is our closest laboratory for studying extreme gravity.

你不必总是知道你要去哪里，只要你继续前进。

历史不仅仅是坏人做坏事的故事，也是好人无所作为的故事。
