While I am describing to you how Nature works, you won't understand why Nature works that way. But you see, nobody understands that.

You see, I get such fun out of thinking that I don't want to destroy this most pleasant machine that makes life such a big kick.

We are very lucky to be living in an age in which we are still making discoveries. It is like the discovery of America-you only discover it once. The age in which we live is the age in which we are discovering the fundamental laws of nature, and that day will never come again. It is very exciting, it is marvelous, but this excitement will have to go.

What Do You Care What Other People Think?

For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

Our imagination is stretched to the utmost, not, as in fiction, to imagine things which are not really there, but just to comprehend those things which are there.

The real problem in speech is not precise language. The problem is clear language.
