The advancement of mathematics is due to those who are driven not by the desire for application but by the joy of discovery.

Data is a precious thing and will last longer than the systems themselves.

Never stop asking questions, because that's where discovery begins.

每一次表演都是新的挑战。

An eye for an eye will only make the whole world blind.

历史的真相往往藏在其沉默之中。

I find I'm so excited. I can barely sit still or hold a thought in my head. I think it the excitement only a free man can feel, a free man at the start of a long journey whose conclusion is uncertain. I hope I can make it across the border.I hope the Pacific is as blue as it has been in my dreams. I hope to see my friend, and shake his hand. I hope.
