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

The science window gives you a view of the world, and the religion window gives you a totally different view. You can't look at both of them at the same time, but they're both true.

If women are 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.

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.

You have this world of mathematics, which is very real and which contains all kinds of wonderful stuff. And then we also have the world of nature, which is real, too. And that, by some miracle, the language that nature speaks is the same language that we invented for mathematics. That's just an amazing piece of luck, which we don't understand.

Do not imagine that you have to know everything before you can do anything. My own best work was done when I was most ignorant.
