I grew up in England and we spent most of the time on Latin and Greek and very little on science, and I think that was good because it meant we didn't get turned off. It was... Science was something we did for fun and not because we had to.

I think it's a big mistake to decide too soon what you're going to do with your life.

It's better to get mugged than to live a life of fear.

We should try to introduce our children to science today as a rebellion against poverty and ugliness and militarism and economic injustice.

The purpose of thinking about the future is not to predict it but to raise people's hopes.

For any speculation which does not at first glance look crazy, there is no hope.

The bottom line for mathematicians is that the architecture has to be right. In all the mathematics that I did, the essential point was to find the right architecture. It's like building a bridge. Once the main lines of the structure are right, then the details miraculously fit. The problem is the overall design.
