Almost everything about the universe is astounding. I think the most amazing thing is how gifted we are - we are only monkeys who came down from the trees just recently. We have these amazing gifts of music and mathematics and painting and Olympic running.

Science and religion are, of course, two different ways of looking at the universe; and it's the same universe with two different windows.

Technology must be guided and driven by ethics if it is to do more than provide new toys for the rich.

I don't know, but I think it's quite possible that the more science you teach kids in school the more it turns them off, so I don't know. I mean you never can tell which way it will go.

We must be careful not to discourage our twelve-year-olds by making them waste the best years of their lives preparing for examinations.

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

In the long run, the only solution I see to the problem of diversity is the expansion of mankind into the universe by means of green technology... Green technology means we do not live in cans but adapt our plants and our animals and ourselves to live wild in the universe as we find it... When life invades a new habitat, she never moves with a single species. She comes with a variety of species, and as soon as she is established, her species spread and diversify further. Our spread through the galaxy will follow her ancient pattern.
