Quantum Quotes - page 8
You turned into a cat! A SMALL cat! You violated Conservation of Energy! That's not just an arbitrary rule, it's implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get FTL signalling! And cats are COMPLICATED! A human mind can't just visualise a whole cat's anatomy and, and all the cat biochemistry, and what about the neurology? How can you go on thinking using a cat-sized brain?
Eliezer Yudkowsky
A new theory by the author has been added, which draws the physical inferences consequent on the extension of the foundations of geometry beyond Reimann... and represents an attempt to derive from world-geometry not only gravitational but also electromagnetic phenomena. Even if this theory is still only in its infant stage, I feel convinced that it contains no less truth than Einstein's Theory of Gravitation-whether this amount of truth is unlimited or, what is more probable, is bounded by the Quantum Theory.
Hermann Weyl
A new development began for relativity theory after 1925 with its absorption into quantum physics. The first great success was scored by Dirac's quantum mechanical equations of the electron, which introduced a new sort of quantities, the spinors, besides the vectors and tensors into our physical theories. ...But difficulties of the gravest kind turned up when one passed from one electron or photon to the interaction among an indeterminate number of such particles. In spite of several advances a final solution of this problem is not yet in sight and may well require a deep modification of the foundation of quantum mechanics, such as would account in the same basic manner for the elementary electric charge e as relativity theory and our present quantum mechanics account for c and h.
Hermann Weyl
This fact, that all charges are integral multiples of a fundamental unit, is still one of the unexplained puzzles of fundamental physics. It does not in any way contradict electromagnetic theory, but it is not predicted by it, and until we have a more fundamental theory that explains it, we shall not feel that we really understand electromagnetic phenomena thoroughly. Presumably its explanation will not come until we understand quantum theory more thoroughly than we do at present.
John C. Slater
A child's mind is open to learn, and it is a cruel and heartless thing to fill it with myth disguised as history, to impose upon it a bogus lifelong perspective, and close it up again, leaving it proof against common sense and all argument. Surely, if there is a hell, people who do this are the ones who will get their tickets punched.
A judgment by the God who devised the quantum system should be considerably different from the one the Reverend Koestler envisions. I gave you a sky full of stars, and you never raised your eyes. I gave you a brain, and you never used it.
Jack McDevitt
The trouble I have with astrophysics or quantum mechanics is the same problem I have with philosophy; which is: initially it is mind blowing, then it is fascinating, then it is disturbing, then it is almost uncomprehensible, then it's fascinating again, then you disappear up your own ass.
Craig Ferguson
Scientific realism in classical (i. e. pre-quantum) physics has remained compatible with the naive realism of everyday thinking on the whole; whereas it has proven impossible to find any consistent way to visualize the world underlying quantum theory in terms of our pictures in the everyday world. The general conclusion is that in quantum theory naive realism, although necessary at the level of observations, fails at the microscopic level.

I also knew the formula that expresses the energy distribution in the normal spectrum. A theoretical interpretation therefore had to be found at any cost, no matter how high. It was clear to me that classical physics could offer no solution to this problem, and would have meant that all energy would eventually transfer from matter to radiation. ...This approach was opened to me by maintaining the two laws of thermodynamics. The two laws, it seems to me, must be upheld under all circumstances. For the rest, I was ready to sacrifice every one of my previous convictions about physical laws. ...[One] finds that the continuous loss of energy into radiation can be prevented by assuming that energy is forced at the outset to remain together in certain quanta. This was purely a formal assumption and I really did not give it much thought except that no matter what the cost, I must bring about a positive result.
Max Planck
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...If you can figure out how to take advantage of this quantum multitasking, we can build computers that can do computations that no classical computer could do even if it were the size of the entire universe.
Seth Lloyd
The development during the present century is characterized by two theoretical systems essentially independent of each other: the theory of relativity and the quantum theory. The two systems do not directly contradict each other; but they seem little adapted to fusion into one unified theory.
Albert Einstein
The flute sings of an ancient riverbead one hundred fathoms deep, far below the Potaro River that runs to the Waterfall. Two rivers then. The visible Potaro runs to the Waterfall. The invisible stream of the river of the dead runs far below, far under our knees. The flute tells of the passage of the drowned river of the dead and the river of the living are one quantum stream possessed of four banks.
