Niels Bohr Quotes

I think we can safely assume that no one understands quantum mechanics.

Although quantum mechanics has been around for nearly 70 years, it is still not generally understood or appreciated, even by those that use it to do calculations.

Anyone who can contemplate quantum mechanics without getting dizzy hasn't understood it.

No one really understands quantum mechanics.

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

All of modern physics is governed by that magnificent and thoroughly confusing discipline called quantum mechanics ... It has survived all tests and there is no reason to believe that there is any flaw in it. We all know how to use it and how to apply it to problems; and so we have learned to live with the fact that nobody can understand it.

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.

I recently forced myself to read a book on quantum physics, just to try and learn something new. I was confused by the middle of the first sentence and it all went downhill from there. The only thing I can remember learning is that a parallel universe can theoretically be contained on the head of a needle. I don't really know what that means, but I am now more careful handling needles.

I think I can safely say that nobody understands Quantum Mechanics.

If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.

A person who wasn't outraged on first hearing about quantum theory didn't understand what had been said.

Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices.

What're quantum mechanics?" "I don't know. People who repair quantums, I suppose.

If you aren't confused by quantum physics, then you haven't really understood it

Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.

If you have nothing in quantum mechanics, you will always have something.

I never studied science or physics at school, and yet when I read complex books on quantum physics I understood them perfectly because I wanted to understand them. The study of quantum physics helped me to have a deeper understanding of the Secret, on an energetic level.

[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd.

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.

If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.

Spooky action at a distance.

I don’t think anything about Einstein’s theory because I don’t understand it.

The more you study quantum mechanics, the more crazy and incomprehensible it becomes. You truly do need a Ph.D. in very high level math and science to understand it at a high, high level.

[Heisenberg's seminal 1925 paper initiating quantum mechanics marked] one of the great jumps—perhaps the greatest—in the development of twentieth century physics.

The more one chases the quanta, the better they hide themselves.
