There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.

If you keep proving stuff that others have done, getting confidence, increasing the complexities of your solutions - for the fun of it - then one day you'll turn around and discover that nobody actually did that one! And that's the way to become a computer scientist.

I find that teaching and the students keep life going, and I would never accept any position in which somebody has invented a happy situation for me where I don't have to teach. Never.

I have the advantage of having found out how hard it is to get to really know something. How careful you have to be about checking your experiments. How easy it is to make mistakes and fool yourself. I know what it means to know something.

Phenomena complex-laws simple....Know what to leave out.

I love only nature, and I hate mathematicians.

There is no authority who decides what is a good idea.
