真相很少是纯粹的，也从不简单。
The more one judges, the less one loves.
想得大，想得远。
科学家不是给出正确答案的人，而是提出正确问题的人。
我已经不再年轻，不再知道一切。
As to the gods, I do not know whether they exist or not, nor what they are like in form; for there are many things that hinder sure knowledge, the obscurity of the matter and the shortness of human life.
感谢所有支持我的人，你们的爱是我最大的动力。
We are all patchworks of our ancestors.
