To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature.

Physics isn`t the most important thing. Love is.

What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school - and you think I'm going to explain it to you so you can understand it? No, you are not going to be able understand it. [...] You see my physics students don't understand it either. That is because I don't understand it. Nobody does.

People are always asking for the latest developments in the unification of this theory with that theory, and they don't give us a chance to tell them anything about what we know pretty well. They always want to know things that we don't know.

The "paradox" is only a conflict between reality and your feeling of what reality "ought to be".

Poets say science takes away from the beauty of the stars - mere globs of gas atoms. Nothing is "mere." I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one-million-year-old light. A vast pattern - of which I am a part - perhaps my stuff was belched from some forgotten star, as one is belching there. Or see them with the greater eye of Palomar, rushing all apart from some common starting point when they were perhaps all together. What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined!

We cannot define anything precisely! If we attempt to, we get into that paralysis of thought that comes to philosophers, who sit opposite each other, one saying to the other "You don't know what you are talking about!" The second one says "What do you mean by know? What do you mean by talking? What do you mean by you?", and so on.

Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.

I think I can safely say that nobody understands quantum mechanics.

The first principle is that you must not fool yourself, and you are the easiest person to fool.

I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong.

Scientific knowledge is an enabling power to do either good or bad - but it does not carry instructions on how to use it.

Science is what we have learned about how to keep from fooling ourselves.

I think it`s much more interesting to live not knowing than to have answers which might be wrong.

It doesn`t seem to me that this fantastically marvelous universe, this tremendous range of time and space and different kinds of animals, and all the different planets, and all these atoms with all their motions, and so on, all this complicated thing can merely be a stage so that God can watch human beings struggle for good and evil - which is the view that religion has. The stage is too big for the drama.
