Richard P. Feynman Quotes

No one really 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 not shocked by quantum mechanics has not yet understood it.

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

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

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.

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

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

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.

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

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.

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

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

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

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

Both the old and new physics were dealing with shadow-symbols, but the new physics was forced to be aware of that fact - forced to be aware that it was dealing with shadows and illusions, not reality.

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

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.

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