Quantum Mechanics Quotations

God does not play dice with the universe.

God is clever, but not dishonest.

God is subtle, but He is not malicious.

Those who are not shocked when they first come across quantum mechanics cannot possibly have understood it.

If anybody says he can think about quantum problems without getting giddy, that only shows he has not understood the first thing about them.

To Wolfgang Pauli:

We all agree that your theory is crazy, but is it crazy enough?

We must be clear that, when it comes to atoms, language can be used only as in poetry.

If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.

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

There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe that there ever was such a time. … On the other hand, I think it is safe to say that no one understands quantum mechanics. … Do not keep saying to yourself, if you can possibly avoid it, ‘But how can it be like that?’, because you will get ‘down the drain’ into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.
