Life is nature's way to give mind oportunities it wouldn't otherwise had.

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

I'm prejudiced about education altogether. I think it's terribly overrated. It wastes a tremendous amount of time - especially for women, it's particularly badly timed. If they're doing a Ph.D., they have a conflict between raising a family or finishing the degree, which is just at the worst time - between the ages of 25 to 30 or whatever it is. It ruins the five years of their lives.

Some things go better than you expected, other things go worse, so I'm... I think the only sensible thing is just to wait and see and what I'm doing when I'm writing books - I'm not doing science so much anymore.

For a physicist mathematics is not just a tool by means of which phenomena can be calculated, it is the main source of concepts and principles by means of which new theories can be created.

We won't really understand the brain until we can make models of it which are analog rather than digital, which nobody seems to be trying very much.

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