Certainly in the United States, you have a constituency in the form of the weapons laboratories, and you also have the branches of the armed services that are involved with nuclear weapons deployment, especially the naval submarine operations and also the air force's land-based ICBM operations. So they have a big lobby in Washington.

Science makes no claim to infallibility; it leaves that claim to be made by theologians.

The deeper our insight into the methods of nature . . . the more incredible the popular Christianity seems to us.

The Universe is a pretty big place... And the one thing I know about nature is it hates to waste anything. So I guess I'd say if it is just us, an awful lot of space is going to waste. The earth is not alone, it is not like a single apple on a tree; there are many apples on the tree, and there are many trees in the orchard.

The thing that I focus on because I don't think it gets enough attention is that among the world's major powers, there is still a nuclear balance of terror - I'm talking about between the United States and Russia, the United States and China.

I am in love with this world. It has been my home. It has been my point of outlook into the universe. I have never bruised myself against it nor tried to use it ignobly.
