I have the freedom to do what I want... bright people to talk to every day.

To me, mathematics is like playing the violin. Some people can do it - others can't. If you don't have it, then there's no point in pretending.

The pain of childbirth is not remembered. It's the child that's remembered.

It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment.

I think it's much better to have your eyes open, but on the other hand, of course it can do harm if you tell people look, there's all these terrible things you can do and then some idiot may go ahead and do it.

I am saying that all predictions concerning climate are highly uncertain.

All the time worrying about pushing the children and getting them to be mathematically literate and all that stuff. It's terribly hard on the kids. It's also hard on the teachers. And I think it's totally useless.
