Quotes & Sayings About Quantum Theory

I'm very moved by chaos theory, and that sense of energy. That quantum physics. We don't really, in Hindu tradition, have a father figure of a God. It's about cosmic energy, a little spark of which is inside every individual as the soul. — Bharati Mukherjee

Here the attention of the research workers is primarily directed to the problem of reconciling the claims of the special relativity theory with those of the quantum theory. The extraordinary advances made in this field by Dirac ... leave open the question whether it will be possible to satisfy the claims of the two theories without at the same time determining the Sommerfeld fine-structure constant. — Werner Heisenberg

Quantum physics is no longer an abstract theory for specialists. We must now absolutely include it in our education and also in our culture. — Claude Cohen-Tannoudji

There is a mathematical underpinning that you must first acquire, mastery of each mathematical subdiscipline leading you to the threshold of the next. In turn you must learn arithmetic, Euclidian geometry, high school algebra, differential and integral calculus, ordinary and partial differential equations, vector calculus, certain special functions of mathematical physics, matrix algebra, and group theory. For most physics students, this might occupy them from, say, third grade to early graduate school - roughly 15 years. Such a course of study does not actually involve learning any quantum mechanics, but merely establishing the mathematical framework required to approach it deeply. — Carl Sagan

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory. — Michio Kaku

In his first philosophical lecture on modern physics that Pauli gave in November 1934 to the Zurich Philosophical Society he said that only a formulation of quantum theory would be satisfactory which expresses the relation between the value of [the fine structure constant] and charge conservation in the same complementary was as that between the space-time description and energy-momentum conservation. — Charles P. Enz

Quantum theory thus reveals a basic oneness of the universe. It shows that we cannot decompose the world into independently existing smallest units. As we penetrate into matter, nature does not show us any isolated "building blocks," but rather appears as a complicated web of relations between the various parts of the whole. These relations always include the observer in an essential way. The human observer constitute the final link in the chain of observational processes, and the properties of any atomic object can be understood only in terms of the object's interaction with the observer. — Fritjof Capra

Another very good test some readers may want to look up, which we do not have space to describe here, is the Casimir effect, where forces between metal plates in empty space are modified by the presence of virtual particles.

Thus virtual particles are indeed real and have observable effects that physicists have devised ways of measuring. Their properties and consequences are well established and well understood consequences of quantum mechanics. — Gordon L. Kane

Anyone who is not shocked by quantum theory has not understood it. — Niels Bohr

String theory?[pause] It closed the conceptual gulp between relativity and quantum mechanics. It postulates that subatomic particles are not points, but strings, about one planck length long. The rate at which strings vibrate can generate the properties of all known particles. Huh? How did I know that? — Willie Garson

Belief, like fear or love, is a force to be understood as we understand the theory of relativity and principals of uncertainty. Phenomena that determine the course of our lives. Yesterday, my life was headed in one direction. Today, it is headed in another. Yesterday, I believe I would never have done what I did today. These forces that often remake time and space, that can shape and alter who we
imagine ourselves to be, begin long before we are born and continue after we perish. Our lives and our choices, like quantum trajectories, are understood moment to moment. That each point of intersection, each encounter, suggest a new potential direction. Proposition, I have fallen in love with Luisa Rey. Is this possible? I just met her and yet, I feel like something important has happened to me. — David Mitchell

Like the very quantum particles we study, we must be comfortable allowing our view of the world to exist in superposition. — Kevin Michel

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. — Ravi Gomatam

The physicist is familiar with the fact that the classical laws of physics are modified by quantum theory, especially at low temperature. There are many instances of this. Life seems to be one of them, a particularly striking one. Life seems to be orderly and lawful behaviour of matter, not based exclusively on its tendency to go over from order to disorder, but based partly on existing order that is kept up. — Erwin Schrodinger

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables. — Werner Heisenberg

...a useful coorective to the triumphalism of some scientists. For example, Maddox went out of his way to emphasise the provisional nature of much physics - he referred to black holes as 'putative' only, to the search for theories of everything as 'the embodiment of a belief, even a hope' and stated that the reason why the quantum gravity project is 'becalmed' right now is because 'the problem to be solved is not yet fully understood' and that the idea that the universe began with a Big Bang 'will be found to be false'. — Peter Watson

You create reality by looking at it, is what Quantum Mechanics suggests. This may sound outrageously magical. Quantum Mechanics or QM, is the physics of the microscopic world. It is a strange theory that took birth in the early 20th century and continues to dazzle scientists and philosophers today. So much so, that QM is regarded as the gateway to the world of consciousness, bringing science and spiritualty together. Science has entered domain of philosophy and consciousness/spirituality through Quantum Mechanics, making it a hot topic for debate among intellectuals from both scientific and philosophical domains. Some physicists even insist on making philosophy of physics! — Sharad Nalawade

I think that the obscurity of the theory is not the fault of quantum mechanics but is rather due to the limited capacity of our imagination. When we try to "see" the quantum world, we are rather like moles used to living underground, to whom someone is trying to describe the Himalayas. Or like the men imprisoned at the back of Plato's cave. — Carlo Rovelli

The treatment of the indeterminacy principle as absolute and final can then be criticized as constituting an arbitrary restriction on scientific theories, since it does not follow from the quantum theory as such, but rather from the assumption of the unlimited validity of certain of its features, an assumption that can in no way ever be subjected to experimental proof. — David Bohm

Every reflection today, whether nihilist or positivist, gives birth, sometimes without knowing it, to
standards that science itself confirms. The quantum theory, relativity, the uncertainty of interrelationships,
define a world that has no definable reality except on the scale of average
greatness, which is our own. The ideologies which guide our world were born in the time of absolute
scientific discoveries. Our real knowledge, on the other hand, only justifies a system of thought based on
relative discoveries. "Intelligence," says Lazare Bickel, "is our faculty for not developing what we think
to the very end, so that we can still believe in reality." Approximative thought is the only creator of
reality. — Albert Camus

The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as the elementary quantum of action is to the Quantum Theory: it is its absolute core. — Max Planck

The chemist Peter Atkins correctly observed, "Natural selection was a revolution and a stepping-stone to fame; so was relativity, and so was quantum theory. The sheer thrill of discovery is the spur to greater effort. All young scientists aspire to revolution." The same can't be said for theologians (Martin Luther is a rare exception), who either bear their heresies in silence or aspire only to trivial reinterpretations of church doctrine. — Jerry A. Coyne

And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it. — Niels Bohr

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics. — Carl Friedrich Von Weizsacker

Combining quantum entanglement with wormholes yields mind boggling results about black holes. But I don't trust them until we have a theory of everything which can combine quantum effects with general relativity. i.e. we need to have a full blown string theory resolve this sticky question. — Michio Kaku

Unfortunately, most of the prevailing descriptions of quantum theory tend to emphasize puzzles and paradoxes in a way that makes philosophers, theologians, and even non-physicist scientists leery of actually using in any deep way the profound changes in our understanding of human beings in nature wrought by the quantum revolution. Yet, properly presented, quantum mechanics is thoroughly in line with our deep human intuitions. It is the 300 years of indoctrination with basically false ideas about how nature works that now makes puzzling a process that is completely in line with normal human intuition. — Paul Davies

For the most part, quantum theory has been of little practical value in my life. — Jenny Diski

It would take a civilization far more advanced than ours, unbelievably advanced, to begin to manipulate negative energy to create gateways to the past. But if you could obtain large quantities of negative energy - and that's a big "IF" - then you could create a time machine that apparently obeys Einstein's equation and perhaps the laws of quantum theory. — Michio Kaku

Fine Structure Constant: Fundamental numerical constant of atomic physics and quantum electrodynamics, defined as the square of the charge of the electron divided by the product of Planck's constant and the speed of light. — Steven Weinberg

Should a priest reject relativity because it contains no authoritative exposition on the doctrine of the Trinity? Once you realize that the Bible does not purport to be a textbook of science, the old controversy between religion and science vanishes ... The doctrine of the Trinity is much more abstruse than anything in relativity or quantum mechanics; but, being necessary for salvation, the doctrine is stated in the Bible. If the theory of relativity had also been necessary for salvation, it would have been revealed to Saint Paul or to Moses. — Georges Lemaitre

Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things. — Brian Greene

In Einstein's theory of relativity the observer is a man who sets out in quest of truth armed with a measuring-rod. In quantum theory he sets out with a sieve. — Arthur Eddington

No. I do not think that. For the new principle that is involved is a genuinely physical one: it is, in my opinion, nothing else than the principle of quantum theory over again. — Erwin Schrodinger

Twisting space-time into knots requires energy on a scale that will not be available within the next several centuries or even millenia-if ever. Even if all the nations of the world were to band together to build a machine that could probe hyperspace, they would ultimately fail. And, as Guth points out, the temperatures necessary to create a baby universe in the laboratory is 1,000 trillion trillion degrees, far in excess of anything available to us. In fact, that temperature is much greater than anything found in the interior of a star. So, although it is possible that Einstein's laws and the laws of quantum theory might allow for time travel, this is not within the capabilities of earthlings like us, who can barely escape the feeble gravitational field of our own planet. While we can marvel at the implications of wormhole research, realizing its potential is strictly reserved for advanced extraterrestrial civilizations. — Michio Kaku

Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking. — Nathan Myhrvold

The situation today is, we haven't got a good model to explain partial reflection by two surfaces; we just calculate the probability that a particular photomultiplier will be hit by a photon reflected from a sheet of glass. I have chosen this calculation as our first example of the method provided by theory of quantum electrodynamics. I am going to show you "how we count the beans"-what the physicists do to get the right answer. I am not going to explain how the photons actually "decide" whether to bounce back or go through; that is not known. (Probably the question has no meaning.) I will only show you how to calculate the correct probability that light will be reflected from glass of a given thickness, because that's the only thing physicists know how to do! What we do to get the answer to this problem is analogous to the things we have to do to get the answer to every other problem explained by quantum electrodynamics. — Richard Feynman

The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena. — Erwin Schrodinger

Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism - all together in one package, but only if the universe has more dimensions than the ones that we see. — Brian Greene

As Sommerfeld said in his famous text "Spectral Lines and Atomic Constitution," on which a generation of physicists learned the subject, "In the fine structure constant e is the representative of the electron theory, h the appropriate representative of the quantum theory, c comes from relativity and characterizes it in contrast to classical theory. — Emilio Segre

The quantum theory is based on the idea that there is a probability that all possible events, no matter how fantastic or silly, might occur. — Michio Kaku

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased. — Lee Smolin

You have nothing to do but mention the quantum theory, and people will take your voice for the voice of science, and belive anything. — George Bernard Shaw

In fact, the mere act of opening the box will determine the state of the
cat, although in this case there were three determinate states the cat
could be in: these being Alive, Dead, and Bloody Furious. — Terry Pratchett

When you look at a vacuum in a quantum theory of fields, it isn't exactly nothing. — Peter Higgs

Let us begin with the fine-structure constant ... The fine-structure constant is really the ratio of two natural units or atoms of action ... We obtain action when we multiply energy by time ... We are challenged to find a unified theory of electric particles and radiation in which the electrostatic type of action and the quantum type of action are traced to their source. — Arthur Stanley Eddington

Quantum field theory arose out of our need to describe the ephemeral nature of life. — Anthony Zee

Naively, special relativity would therefore tell us that those particles should be able to travel forwards and backwards in time as well. But so far as we know, neither particles nor anything else we are aware of can actually travel backwards in time. What happens instead is that oppositely charged antiparticles replace the reverse-time-traveling particles. Antiparticles reproduce the effects the reverse-time-traveling particles would have so that even without them, quantum field theory's predictions are compatible with special relativity. — Lisa Randall

For bedtime reading, I usually curl up with a good monograph on quantum physics or string theory, my specialty. But since I was a child, I have been fascinated by science fiction. My all-time favorite is 'The Foundation Trilogy,' by Isaac Asimov. — Michio Kaku

Quantum mechanics, that brilliantly successful flagship theory of modern science, is deeply mysterious and hard to understand. Eastern mystics have always been deeply mysterious and hard to understand. Therefore, Eastern mystics must have been talking about quantum theory all along. — Richard Dawkins

All perception is the result of electrical impulses in the brain - the world of the individual is tantamount to a highly advanced computer running and analyzing programs in its working memory. — Kevin Michel

I read a lot of science books - I love cosmology, quantum theory, particle physics. So my idea of a great read would probably put you directly into a coma. — Augusten Burroughs

So we may now pose a question which could be answered only if we have a quantum theory of gravity. What is the nature of the information trapped in a quantum black hole? Keep this in mind as we go ahead and explore the different approaches to quantum gravity, for a good test of a theory of quantum gravity is how well it is able to answer this question. — Lee Smolin

It would probably be wiser to nail up over the door of the new quantum theory a notice, 'Structural alterations in progress - No admittance except on business', and particularly to warn the doorkeeper to keep out prying philosophers. — Arthur Stanley Eddington

According to quantum field theory, fields alone are real. They are the substance of the universe and not 'matter'. Matter is simply the momentary manifestation of interacting fields which, intangible and insubstantial as they are, are the only real things in the universe. — Gary Zukav

If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so. — James Lovelock

I've always been fascinated by science - anatomy, quantum physics, space and time theory. I don't understand these things, but the mystery is a part of what attracts me to them. That the world I live in now is complex beyond my understanding only encourages me to believe that there are wild possibilities in creation beyond even the things of this dimension of time and space. If this universe has alternate dimensions outside of our understanding, isn't it possible that we might exist in a life beyond this one, in another kind of dimension that is fuller and more alive than the one we know? — Bethany Pierce

I have a theory which I suspect is rather immoral,' Smiley went on, more lightly. 'Each of us has only a quantum of compassion. That if we lavish our concern on every stray cat, we never get to the centre of things. — John Le Carre

the most sophisticated diagnostic equipment available in the world, which detects and measures energies and frequencies in the body. This diagnostic equipment includes devices you probably heard of like MRIs (Magnetic Resonance Imaging), PET scans (Positron Emission Tomography), CAT scans (Computed Axial Tomography), EEGs (Electro encephalograms), EKGs (Electrocardiography), ultrasound devices and more. Our medical system diagnoses the body energetically with modern physics (Quantum Field Theory), and then treats with drugs and surgery (Newtonian Science). What is wrong with this picture? — Bryant A. Meyers

A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century. — Carlo Rovelli

I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics. — Brian Greene

There was a long history of speculation that in quantum gravity, unlike Einstein's classical theory, it might be possible for the topology of spacetime to change. — Edward Witten

Despite the earnest belief of most of his fans, Einstein did not win his Nobel Prize for the theory of relativity, special or general. He won for explaining a strange effect in quantum mechanics, the photoelectric effect. His solution provided the first real evidence that quantum mechanics wasn't a crude stopgap for justifying anomalous experiments, but actually corresponds to reality. And the fact that Einstein came up with it is ironic for two reasons. One, as he got older and crustier, Einstein came to distrust quantum mechanics. Its statistical and deeply probabilistic nature sounded too much like gambling to him, and it prompted him to object that "God does not play dice with the universe." He was wrong, and it's too bad that most people have never heard the rejoinder by Niels Bohr: "Einstein! Stop telling God what to do. — Sam Kean

A theory of reality must not only explain reality, but also knowledge about that reality because knowing reality is part of reality. — Ashish Dalela

You said, 'Why do I frighten you?'
Frighten me? Yes you do frighten me. You act as though we will be together for ever. You act as though there is infinite pleasure and time without end. How can I know that? My experience has been that time always ends. In theory you are right, the quantum physicists are right, the romantics and the religious are right. — Jeanette Winterson

Those who are not shocked when they first come across quantum theory cannot possibly have understood it. — Niels Bohr

The scientists often have more unfettered imaginations than current philosophers do. Relativity theory came as a complete surprise to philosophers, and so did quantum mechanics, and so did other things. — Robert Nozick

To leave the atom constituted as it was but to interfere with the probability of its undetermined behaviour, does not seem quite so drastic an interference with natural law as other modes of mental interference that have been suggested. (Perhaps that is only because we do not understand enough about these probabilities to realize the heinousness of our suggestion.) Unless it belies its name, probability can be modified in ways which ordinary physical entities would not admit of. There can be no unique probability attached to any event or behaviour; we can only speak of 'probability in the light of certain given information,' and the probability alters according to the extent of the information. It is, I think, one of the most unsatisfactory features of the new quantum theory in its present stage that it scarcely seems to recognize this fact, and leaves us to guess at the basis of information to which its probability theorems are supposed to refer. — Arthur Stanley Eddington

The current leading candidates for dark matter are particles predicted to exist from supersymmetric theories, extensions of current particle physics that include a new symmetry of Nature. The reader may recognize the "super" in supersymmetry from superstring theory, a candidate theory for unifying general relativity and quantum mechanics. As of the winter of 2014, no evidence for supersymmetry had been found, despite decades of intense search and the enthusiastic support of many physicists. At this point, it is unclear and somewhat doubtful that supersymmetry is realized in Nature. — Marcelo Gleiser

Scientists, therefore, are responsible for their research, not only intellectually but also morally. This responsibility has become an important issue in many of today's sciences, but especially so in physics, in which the results of quantum mechanics and relativity theory have opened up two very different paths for physicists to pursue. They may lead us - to put it in extreme terms - to the Buddha or to the Bomb, and it is up to each of us to decide which path to take. — Fritjof Capra

My training in science is actually one that is very critical of mechanistic science. I was trained in quantum theory which emerged at the turn of the last century. We are a whole century behind in absorbing the leaps that quantum theory made for the human mind. — Vandana Shiva

The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively. — Niels Bohr

It was like bouncing tennis balls off a mystery piece of furniture and deducing, from the direction in which the balls ricocheted, whether it was a chair or a table or a Welsh dresser. — Marcus Chown

The theory of relativity and quantum mechanics argue that you can twist time and space, that something can appear out of nothing, and that a cat can be both alive and dead at the same time. This makes a mockery of our common sense, yet nobody seeks to protect innocent schoolchildren from these scandalous ideas. Why? The theory of relativity makes nobody angry, because it doesn't contradict any of our cherished beliefs. Most people don't care an iota whether space and time are absolute or relative. If you think it is possible to bend space and time, well, be my guest. Go ahead and bend them. What do I care? In contrast, Darwin has deprived us of our souls — Yuval Noah Harari

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

It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct. — Michio Kaku

In Darwin's theory, you just have to substitute 'mutations' for his 'slight accidental variations' (just as quantum theory substitutes 'quantum jump' for 'continuous transfer of energy'). In all other respects little change was necessary in Darwin's theory ... — Erwin Schrodinger

Sometimes, we do not need a lot of words to convey meaning. For example, imagine a lovely sunset. — Richard Gentle

We are at a time when postmodernism defies certainty, truth, and meaning; when spiritualism dabbles in quantum theory; and when randomness has become the order of the day. Isn't it ironic that at the same time, the world is on the edge of financial bankruptcy because we have conducted our financial affairs in a random fashion, as if there are no absolutes? — Ravi Zacharias

The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It's surprising that the theory still hasn't been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate. — Richard P. Feynman

A mathematician says that an electromagnetic wave travels from Andromeda to your eye and that it also extends from Andromeda to your eye. — Bill Gaede

Peace begins when expectations end. — Sri Chinmoy

Realizing its fundamental importance in understanding spectral lines, in atomic physics and in the theory of how light and electrons interact, quantum electrodynamics, Pauli and Heisenberg were determined to derive it from quantum theory rather than introducing it from the start. They believed that if they could find a version of quantum electrodynamics capable of producing the fine structure constant, it would not contain the infinities that marred their theories. — Arthur I. Miller

The quantum hologram is a mechanism to explain this concept of the ancients of the Akashic Records. It also explains Rupert Sheldrake's work among animals [his theory of morphic fields and morphic resonance, leading to a vision of a living, developing universe with its own inherent memory]. — Edgar Mitchell

Wolfgang Pauli, in the months before Heisenberg's paper on matrix mechanics pointed the way to a new quantum theory, wrote to a friend, "At the moment physics is again terribly confused. In any case, it is too difficult for me, and I wish I had been a movie comedian or something of the sort and had never heard of physics." That testimony is particularly impressive if contrasted with Pauli's words less than five months later: "Heisenberg's type of mechanics has again given me hope and joy in life. To be sure it does not supply the solution to the riddle, but I believe it is again possible to march forward. — Wolfgang Pauli

When I was at Berkeley, the framework of quantum field theory could calculate the dynamics of electromagnetism. It could roughly describe the motion of the weak nuclear force, radiation. But it hit a brick wall with the strong interaction, the binding force. — David Gross

One readon why it has taken so long to construct a quantum theory of gravity is that all previous quantum theories were background dependent. It proved rather challenging to construct a background independent quantum theory, in which the mathematical structure of the quantum theory made no mention of points, except when identified through networks of relationships. The problem of how to construct a quantum theoretic description of a world in which space and time are nothing but networks of relationships was solved over the last 15 years of the twentieth century. The theory that resulted is loop quantum gravity, which is one of our three roads. — Lee Smolin

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well. — Roy H. Williams

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

If the deep logic of what determines the value of the fine-structure constant also played a significant role in our understanding of all the physical processes in which the fine-structure constant enters, then we would be stymied. Fortunately, we do not need to know everything before we can know something. — John D. Barrow

Niels Bohr brainwashed a whole generation of theorists into thinking that the job (interpreting quantum theory) was done 50 years ago. — Murray Gell-Mann

Because both quantum theory and Einstein's theory of gravity are united in ten-dimensional space, we expect that the question of time travel will be settled decisively by the hyperspace theory. As in the case of wormholes and dimensional windows, the final chapter will be written when we incorporate the full power of the hyperspace theory. — Michio Kaku

The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle. — Werner Heisenberg

Quantum theory tells us, Mr. Thomas, that every point in the universe is intimately connected to every other point, regardless of apparent distance. In some mysterious way, any point on a planet in a distant galaxy is as close to me as you are. — Dean Koontz

There was quantum mechanics, string theory, and then there was the most mind-bending frontier of the natural world, women. — Marisha Pessl

A successful unification of quantum theory and relativity would necessarily be a theory of the universe as a whole. It would tell us, as Aristotle and Newton did before, what space and time are, what the cosmos is, what things are made of, and what kind of laws those things obey. Such a theory will bring about a radical shift - a revolution - in our understanding of what nature is. It must also have wide repercussions, and will likely bring about, or contribute to, a shift in our understanding of ourselves and our relationship to the rest of the universe. — Lee Smolin

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. — Adam Riess

You are deluded if you think that the world around you is a physical construct separate from your own mind. — Kevin Michel

Chinese dialectical reasoning had an impact on the physicist Niels Bohr, who was highly knowledgeable about Eastern thought. He attributed his development of quantum theory in part to the metaphysics of the East. There had been a centuries-long debate in the West about whether light consists of particles or waves. Belief in one was assumed to contradict and render impossible belief in the other. Bohr's solution was to say that light can be thought of in both ways. In quantum theory, light can be viewed either as a particle or as a wave. Just never both at the same time. — Richard E. Nisbett

You are all wave particles when I close my eyes. I am no more entranced by your entanglement than a butterfly is to a bee. — Solange Nicole

A common refrain among theoretical physicists is that the fields of quantum field theory are the "real" entities while the particles they represent are images like the shadows in Plato's cave. As one who did experimental particle physics for forty years before retiring in 2000, I say, "Wait a minute!" No one has ever measured a quantum field, or even a classical electric, magnetic, or gravitational field. No one has ever measured a wavicle, the term used to describe the so-called wavelike properties of a particle. You always measure localized particles. The interference patterns you observe in sending light through slits are not seen in the measurements of individual photons, just in the statistical distributions of an ensemble of many photons. To me, it is the particle that comes closest to reality. But then, I cannot prove it is real either. — Victor J. Stenger
