You'll have received an application from Mr Freeman Dyson to come to work with you as a graduate student. I hope that you will accept him. Although he is only 23 he is in my view the best mathematician in England.

In our time, in the period 1960-1980, we have seen particle physics emerge as the playground of group theory.

Mr Dyson is absolutely unusual in his ability and accomplishments. I can say without reservation that he is the best I have ever had or observed.

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

I know that if I'd had to go and take an exam for acting, I wouldn't have got anywhere. You don't take exams for acting, you take your courage.

I grew up in Cambridge in England, and my love of mathematics dates from those early childhood days.

'I go to U.C. Berkeley and I'm studying engineering, which is totally not related to music, but I really like music. I want to make music my living.'
