I was making a lot of momentous personal decisions. I was still very very young: when the prize was awarded, I was 33; the work I had done when I was 21.

A Swedish newspaper reporter called and said, You've been awarded the Prize. I was quite sure it was a practical joke.

The Nobel Peace Prize is not awarded for what one has done, but hopefully what one will do.

Although I am a public figure, I'm still a little shy. I don't think my own personality is important. I prefer to keep some small dosage of privacy.

I get curious about new things. My real strength is going into a field that has not been investigated before, and finding new approaches to it.

If we have isolated individuals able to inflict enormous harm, imagine what a single lunatic can do with a nuclear weapon. I think the whole base of civil society is at risk.
