I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you...
Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning.
I wouldn’t stop until I figured the damn thing out–it would take me fifteen or twenty minutes. But during the day, other guys would come to me with the same problem, and I’d do it for them in a flash....
How I'm rushing through this! How much each sentence in this brief story contains. The stars are made of the same atoms as the earth. I usually pick one small topic like this to give a lecture on. Poe...
Being the word of God connects the ethical and metaphysical aspects of religion. And finally, that also inspires the inspiration, because if you are working for God and obeying God’s will, you are in...

There is a most profound and beautiful question associated with the observed coupling constant, e - the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has be...
In fact the total amount that a physicist knows is very little. He has only to remember the rules to get him from one place to another and he is all right...
I have to keep going to find out ultimately what is the matter with it in the end.
For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy.
It is impossible to explain honestly the beauties of the laws of nature in a way that people can feel, without their having some deep understanding of mathematics. I am sorry, but this seems to be the...
You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing...

What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it...
