Stephen Hawking Quotes

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

Anyone not shocked by quantum mechanics has not yet understood it.

No one really understands quantum mechanics.

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

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.

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

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.

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.

On quantum theory I use up more brain grease (rough translation of German idiom) than on relativity.

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

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

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.

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.

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

Quantum physics is teaching us that particles themselves don't create particles. It's what Jesus said 2,000 years ago, that it's the Spirit that gives life and that you don't get particles from more particles.

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

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.

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

If everything is made up of little particles and all the little particles follow quantum mechanics, then shouldn't everything just follow quantum mechanics?

You have nothing to do but mention the quantum theory, and people will take your voice for the voice of science, and belive anything.

[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.

Quantum physics fluctuates all the time. But now the fluctuations are not just particles coming into and out of existence, which happens all the time. It's whole universes coming into and out of existence.

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.
