每个圣人都有过去，每个罪人都有未来。

I'm tough, I'm ambitious, and I know exactly what I want. If that makes me a bitch, okay.

Climate models are like time machines - they allow us to peer into possible futures.

Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.

你知道的越多，就越明白自己知道的很少。

数学的力量在于它的普遍性和超越文化界限的能力。

Choose a life of action，not one of ostentation.
