"The question of the origin of the universe is one of the most exciting topics for a scientist to deal with. It reaches far beyond its purely scientific significance, since it is related to human existence, to mythology, and to religion. Furthermore, it deals with questions are connected with the fundamental structure of matter, with elementrary particles."

"Almost all of the material phenomena which occur under terrestrial conditions are recognized as quantum mechanical consequences of the electrical attraction between electrons and nuclei and of the gravitational attraction between massive objects. We should be able, therefore, to express all the relevant magnitudes which characterize the properties of matter in terms of the following six magnitudes: M, m, e, c, G, and h; M is the mass of the proton, m and e are the mass and electrical charge of the electron, c is the light velocity, G is Newton's gravitational constant, and—most importantly—h is the quantum of action ..."

"… conferences with open attendance are very important for the stimulation of young people or other people who are new in the field. … The field of high-energy physics is, as you know, very strongly in the hands of a clique and it is hard for an outsider to enter."

"It is possible to apply statistical methods to the calculation of nuclear processes provided that the energies involved are large in comparison with the lowest excitation energies of nuclei."

"In 1936 Weisskopf proposed to set aside in quantum electrodynamics the divergent effects at small distances, and to consider only the charge of the particle observed at long distances. This assertion anticipated charge and mass renormalization. Later he showed that the self-energy of an electron in Dirac theory diverges only logarithmically, a result that was important for the later development of renormalization theory."

"Self-confidence is an important ingredient that makes for a successful physicist."

"The first time I met Wheeler was in 1961, I was an undergraduate... with a somewhat unorthodox academic record. ...The hope was that ...I would be admitted as a graduate student... At the time I was working as a plumber... I was completely enthralled. John was enthusiastically describing his vision of how space and time would become a wild, jittery, foamy world of s when viewed through a tremendously powerful microscope. He told me that the most profound and exciting problem of physics was to unify Einstein's two great theories—General Relativity and Quantum Mechanics. He explained that only at the Planck distance would elementary particles reveal their true nature, and it would be all about geometry—. To a young aspiring physicist, the stuffy businessman exterior had morphed into an idealistic visionary. I wanted more than anything to follow this man into battle."

"Time is nature's way to keep everything from happening all at once."

"Is the very mechanism for the universe to come into being meaningless or unworkable or both unless the universe is guaranteed to produce life, consciousness and observership somewhere and for some little time in its history-to-be? The quantum principle shows that there is a sense in which what the observer will do in the future defines what happens in the past—even in a past so remote that life did not then exist, and shows even more, that 'observership' is a prerequisite for any useful version of 'reality'."

"If I had to confess, under torture, right now, what I think the simple idea is, I would say it's that we ourselves generate the world; the world is self-generated. But it may well be absolutely wrong."

"I like to think that someone will trace how the deepest thinking of India made its way to Greece and from there to the philosophy of our times."

"I had the good fortune of having my first and only heart attack last January ... I call it good fortune because it taught me that there's a limited amount of time left and I better concentrate on one thing: How come existence? How come the quantum? Maybe those questions sound too philosophical, but maybe philosophy is too important to be left to the philosophers."

"Therefore we can afford many mistakes in the search. The main thing is to make them as fast as possible."

"The question is—what is the question?"

"We are participators in bringing into being not only the near and here but the far away and long ago. We are in this sense, participators in bringing about something of the universe in the distant past and if we have one explanation for what's happening in the distant past why should we need more?"

"Today I think we are beginning to suspect that man is not a tiny cog that doesn’t really make much difference to the running of the huge machine, but rather that there is a much more intimate tie between man and the universe than we heretofore suspected…The physical world is in some deep sense tied to the human being."

"Space tells matter how to move Matter tells space how to curve"

"Of all heroes, Spinoza was Einstein's greatest. No one expressed more strongly than he a belief in the harmony, the beauty, and most of all the ultimate comprehensibility of nature."

"Spacetime tells matter how to move; matter tells spacetime how to curve."

"For all our everyday experience, the geometry of space is smooth and flat. But as we examine it more closely, it must show oscillations. And still more closely, it must show foam, a foam-like structure. And that means that down at the very smallest distances, this idea of before and after really lose their meaning."

"What we think of as smooth simple space is really a wiggly business."

"The best way to learn something is to have to teach it."

"We will first understand how simple the universe is when we realize how strange it is."

"There are many modes of thinking about the world around us and our place in it. I like to consider all the angles from which we might gain perspective on our amazing universe and the nature of existence."

"We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance."

"Of all obstacles to a thoroughly penetrating account of existence, none looms up more dismayingly than “time.” Explain time? Not without explaining existence. Explain existence? Not without explaining time. To uncover the deep and hidden connection between time and existence, to close on itself our quartet of questions, is a task for the future."

"It from bit symbolizes the idea that every item of the physical world has at bottom — at a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe."

"The late, great astrophysicist, philosopher and black hole evangelist John Archibald Wheeler, of Princeton, used to say that the past and the future are fiction, that they only exist in the artifacts and the imaginations of the present."

"Some people think Wheeler's gotten crazy in his later years, but he's always been crazy."

"On your way towards becoming a bad theoretician, take your own immature theory, stop checking it for mistakes, don't listen to colleagues who do spot weaknesses, and start admiring your own infallible intelligence."

"The experimenter dealing with nature faces an outside and often hard world. Natures' curriculum cannot be changed."

"Experimental science is a craft and an art, and part of the art is knowing when to end a fruitless experiment. There is a danger of becoming obsessed with a fruitless experiment even if it goes nowhere."

"It is always a good plan for a speculative experimenter to have two experiments going, or at least one going and one being built."

"Common elements of creativity are originality and imagination. Creativity is intertwined with the freedom to design, to invent and to dream. In engineering and science a creative idea is useful only if it meets three conditions: the constraint of the natural laws, the constraint of cost, and the constraint of technical feasibility."

"Imagination and obsession are the keys to getting a good idea. To help your imagination keep your eyes and ears open. Avoid the "not invented here prejudice"."

"For every good idea, expect to have five, ten, twenty wrong or useless ideas. You cannot avoid the bad ideas if you keep your imagination free. There is no spam filter for bad ideas."

"You may turn a bad idea into a good idea — don't kill the bad idea prematurely. A bad idea can evolve into a good idea."

"I always look for colleagues who are smart, and who know a lot in many fields. The obvious advantage is that he or she may be able to solve the problem that has produced trouble in your work. Also smart and knowledgeable colleagues can save you time, and are interesting and inspiring!"

"The best colleagues are those who will think about your ideas, who will talk with you and offer insight, constructive criticism. No one needs to be crushed for having a new idea."

"If you really want to contribute to our theoretical understanding of physical laws — and it is an exciting experience if you succeed! — there are many things you need to know. First of all, be serious about it!"

"Quantum mechanics as it stands would be perfect if we didn't have the quantum-gravity issue and a few other very deep fundamental problems."

"The usual no-go theorems telling us that hidden variables are irreconcilable with locality, appear to start with fairly conventional pictures of particle systems, detectors, space and time. Usually, it is taken for granted that events at one place in the universe can be described independently from what happens elsewhere. Perhaps one has to search for descriptions where the situation is more complex. Maybe, it needs not be half as complex as superstring theory itself. The conventional Copenhagen interpretation of quantum mechanics suffices to answer all practical questions concerning conventional experiments with quantum mechanics, and the outcome of experiments such as that of Aspect et al can be precisely predicted by conventional quantum mechanics. This is used by some to state that no additional interpretation prescriptions for quantum mechanics are necessary. Yet we insist that the axioms for any "complete" quantum theory for the entire cosmos would present us with as yet unresolved paradoxes."

"In practice, quantum mechanics merely gives predictions with probabilities attached. This should be considered as a normal and quite acceptable feature of predictions made by science: different possible outcomes with different probabilities. In the world that is familiar to us, we always have such a situation when we make predictions. Thus the question remains: What is the reality described by quantum theories? I claim that we can attribute the fact that our predictions come with probability distributions to the fact that not all relevant data for the predictions are known to us, in particular important features of the initial state."

"When investigating theories at the tiniest conceivable scales in nature, almost all researchers today revert to the quantum language, accepting the verdict from the Copenhagen doctrine that the only way to describe what is going on will always involve states in HIlbert space, controlled by operator equations."

"... trying to solve a paradox will lead to new kinds of understanding. And I think that the problem of subjecting black holes to quantum mechanics is a fundamental paradox of the same nature, and the same depth, and the same importance as the paradox that Max Planck was studying at the beginning of the twentieth century."

"Deterministic underlying theories for QM are possible. They are still difficult to construct, but simple "toy models" are possible. These models are not good enough to replace today's existing quantum theories."

"Gerard is a Dutchman. The Dutch are the tallest people in Europe, but Gerard is short and solidly built, with a mustache and the look of a burgher. Like Feynman, 't Hooft has a strong competitive streak, but I am sure that I never got the better of him. Unlike Feynman, he is a product of old Europe — the last great European physicist, inheritor of the mantle of Einstein and Bohr. Although he is six years younger than I am, I was in awe of him in 1981, and rightfully so. In 1999 he was awarded the Nobel Prize for his work leading to the Standard Model of elementary particles."

"Now comes the Einstein–Podolsky–Rosen entangled state. Now I see faces, people saying, "Oh..?" Don't worry! When you go to the concert, you don't need to be able to read the music, to enjoy the music. ...So here... [are] equations. It's a pleasure for my colleague physicists. If you can't read the equation, listen to me. I'm not going to sing, but... listen to the words... the words are... a way of describing the equations, and you don't need to know the mathematics..."

"[W]e obtain the same correlations of polarizations as in Aspect's first experiments."

"Experiments with time-like separation... were only possible about twenty years after the first experiments by Aspect."
