One way to be strong was to be knowledgeable. In so many areas, it was not possible to be knowledgeable without getting a Ph. D. and doing a postdoc. Guns and hunting provided an out for men who wanted to be know-it-alls but who couldn't afford to spend the first three decades of their lives getting up to speed on quantum mechanics or oncology.

String theory is extremely attractive because gravity is forced upon us. All known consistent string theories include gravity, so while gravity is impossible in quantum field theory as we have known it, it is obligatory in string theory.

I expect that mathematicians have classified such fuzzy logics. Certainly they have been much used by physicists. But is there not something to be said for the approach of Euclid? Even now that we know that Euclidean geometry is (in some sense) not quite true? Is it not good to know what follows from what, even if it is not necessarily FAPP? Suppose for example that quantum mechanics were found to resist precise formulation. Suppose that when formulation beyond FAPP was attempted, we find an unmovable finger obstinately pointing outside the subject, to the mind of the observor, to the Hindu scriptures, to God, or even only Gravitation? Would that not be very, very interesting?

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.

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.

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.

The quantum hypothesis will eventually find its exact expression in certain equations which will be a more exact formulation of the law of causality.

We don't have enough parallel universes to allow all uses of all junction types—in the absence of quantum computing the combinatorics are not in our favor...

It seems to me that in understanding MOND and its fundamentals we have only scratched the surface. If the developments of quantum mechanics and relativity are any lesson here, departures of such magnitude from long- and well-tested physics may bring with them completely new concepts, not summarized by mere modifications of the governing actions or the equations of motion. MOND may also turn out to bring in concepts that are presently beyond our ken (as hinted perhaps by the cosmological connotations of a0)....

Our book originated with a wide-ranging physics course for liberal arts students that in its last weeks focused on the mysteries of quantum mechanics. When I (Bruce) first proposed the course at a department meeting, that final focus prompted a faculty member to object: Though what you are saying is correct, presenting this material to nonscientists is the intellectual equivalent of allowing children to play with loaded guns.

Quantum mechanics... developed through some rather messy, complicated processes stimulated by experiment. While it's a very rich and wonderful theory, it doesn't quite have the conceptual foundation of general relativity. Our problem in physics is that everything is based on these two different theories and when we put them together we get nonsense.

Nobody on this planet ever really chooses each other. I mean, it's all a question of quantum physics, molecular attraction and timing.

In both quantum theory and general relativity, we encounter predictions of physically sensible quantities becoming infinite. This is likely the way that nature punishes impudent theorists who dare to break her unity.... If infinities are signs of missing unification, a unified theory will have none. It will be what we call a finite theory.

John Bell devoted most of his efforts to conceptual and theoretical questions. Would he have liked that I also stress the importance of the technological revolutions that were, and will be, enabled by the conceptual revolutions? I cannot tell, but we know that he started his career in accelerator design, and that he always showed a profound respect for technological achievements. I like to think that he would have loved quantum-jumps-based atomic clocks, as well as entangled qubits.

While the new physics was developing in the 20th century, the mechanistic Cartesian world view and the principles of Newtonian physics maintained their strong influence on Western scientific thinking, and even today many scientists still hold to the mechanistic paradigm, although physicists themselves have gone beyond it.
However, the new conception of the universe that has emerged from modern physics does not mean that Newtonian physics is wrong, or that quantum theory, or relativity theory, is right. Modern science has come to realize that all scientific theories are approximations to the true nature of reality; and that each theory is valid for a certain range of phenomena.

I believe in God the way I believe in quarks. People whose business it is to know about quantum physics or religion tell me they have good reason to believe that quarks and God exist. And they tell me that if I wanted to devote my life to learning what they've learned, I'd find quarks and God just like they did.

People used to try to hijack quantum mechanics and its inherent mystery to cast a cloud around determinism, in the hope that free will could survive modern physics. But that never worked very well. Since when does random chance equal free will? The only salvation for volition is a soul and faith and you're not allowed to ask me about that.

In the information-communication civilization of the 21st Century, creativity and mental excellence will become the ethical norm. The world will be too dynamic, complex, and diversified, too cross-linked by the global immediacies of modern (quantum) communication, for stability of thought or dependability of behaviour to be successful.

There is really nothing more pathetic than to have an economist or a retired engineer try to force analogies between the concepts of physics and the concepts of economics. How many dreary papers have I had to referee in which the author is looking for something that corresponds to entropy or to one or another form of energy. Nonsensical laws, such as the law of conservation of purchasing power, represent spurious social science imitations of the important physical law of the conservation of energy; and when an economist makes reference to a Heisenberg Principle of indeterminacy in the social world, at best this must be regarded as a figure of speech or a play on words, rather than a valid application of the relations of quantum mechanics.
