A Quote by Brian Greene
Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.

In quantum mechanics there is A causing B. The equations do not stand outside that usual paradigm of physics. The real issue is that the kinds of things you predict in quantum mechanics are different from the kinds of things you predict using general relativity. Quantum mechanics, that big, new, spectacular remarkable idea is that you only predict probabilities, the likelihood of one outcome or another. That's the new idea.
We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.
One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.
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.
Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It's really counterintuitive.
No one any longer pays attention to - if I may call it - the spirit of physics, the idea of discovery, the idea of understanding. I think it's difficult to make clear to the non-physicist the beauty of how it fits together, of how you can build a world picture, and the beauty that the laws of physics are immutable.
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.
Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics - this is the reason why quantum mechanics seems so foreign to our everyday existence.
To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.
When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'
It is rather fantastic to realize that the laws of physics can describe how everything was created in a random quantum fluctuation out of nothing, and how over the course of 15 billion years, matter could organize in such complex ways that we have human beings sitting here, talking, doing things intentionally.
I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.
Quantum physics is the physics of possibilities. And not just material possibilities, but also possibilities of meaning, of feeling, and of intuiting. You choose everything you experience from these possibilities, so quantum physics is a way of understanding your life as one long series of choices that are in themselves the ultimate acts of creativity.
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
As an adult I discovered that I was a pretty good autodidact, and can teach myself all kind of things. And developed a great interest in a number of different things from how to build a street hot rod from the ground up to quantum mechanics, and those two different kinds of mechanics, and it was really in the sciences, quantum mechanics, molecular biology, I would begin looking at these things looking for ideas, but in fact you don't read it for ideas you read it for curiosity and interest in the subject.
I was not going to be an actor. I was an engineer in physics. That's what I did: I graduated with a physics degree, and I had become a little bit distressed that I'd have to work for somebody - anybody! And I thought, "I'm not going to make a mark on anything. If I can't express myself, then I don't know what the heck I'm going to do with this life." I think it was just one of those germs that said, "No, no, no, you've got to say things. You've got to tell people things. You've got to express your opinion in this life, because that's how you started."
