仅仅活着是不够的……一个人必须有阳光、自由和一朵小花。
"Just living is not enough... one must have sunshine, freedom, and a little flower."
The essence of mathematics lies in its freedom.
未来属于那些拥抱数字化转型的人。
I pursue no objectives, no systems, no tendency; I have no program, no style, no direction.
没有根本的气节，就好像醉汉喝醉酒打人，酒醉时很勇敢，酒醒后勇气全消，没有一点气力。没有以学问为根本的见识，就好像厨师在炉灶前面，面前光亮而背后黑暗。
Making something variable is easy. Controlling duration of constancy is the trick.
改变令人不适，但停滞是致命的。
