A Quote by David Gross

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation.

The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.

Martin Fleischmann

Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child.

Steven Weinberg

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense.

Brian Greene

Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality

Brian Greene

When the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.

Eugene Wigner

If quantum communication and quantum computation are to flourish, a new information theory will have to be developed.

Hans Christian von Baeyer

I count Maxwell and Einstein, Eddington and Dirac, among "real" mathematicians. The great modern achievements of applied mathematics have been in relativity and quantum mechanics, and these subjects are at present at any rate, almost as "useless" as the theory of numbers.

G. H. Hardy

'Participant' is the incontrovertible new concept given by quantum mechanics. It strikes down the 'observer' of classical theory, the man who stands safely behind the thick glass wall and watches what goes on without taking part. It can't be done, quantum mechanics says it...May the universe in some sense be 'brought into being' by the participation of those who participate?

John Archibald Wheeler

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.

Alain Aspect

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.

Brian Greene

I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.

Edward Witten

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.

Dean Koontz

I did my masters in elementary particles. But the foundations of elementary particles is quantum theory and there were too many conceptual problems around quantum theory that I couldn't live with. So I decided I was going to work on the foundations of quantum theory. That's what I did my Ph.D on.

Vandana Shiva

This book is unique. I know of no other which so artfully tackles two of the greatest mysteries of modern science, quantum mechanics, and consciousness. It has long been suspected that these mysteries are somehow related: the authors’ treatment of this thorny and controversial issue is honest, wide-ranging, and immensely readable. The book contains some of the clearest expositions I have ever seen of the strange and paradoxical nature of the quantum world. Quantum Enigma is a pleasure to read, and I am sure it is destined to become a classic.

George Greenstein

While many questions about quantum mechanics are still not fully resolved, there is no point in introducing needless mystification where in fact no problem exists. Yet a great deal of recent writing about quantum mechanics has done just that.
