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

We do not know how much of the environmental change is due to human activities and how much [is due] to long-term natural processes over which we have no control.

The fact that the climate is getting warmer doesn't scare me at all. There's no reason why one should be scared.

What the world needs is a small, compact, flexible fusion technology that could make electricity where and when it is needed. The existing fusion program is leading to a huge source of centralized power, at a price that nobody except a government can afford.

It's us that's really amazing. As far as I can see, our concentration of different abilities in one species - there's nothing I can see that in this Darwinian evolution that could've done that. So it seems to be a miracle of some sort.

So long as you have courage and a sense of humor, it is never too late to start life afresh.

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.
