Quantum Physicists Quotes & Sayings

The strange feature of partial reflection by two surfaces has forced physicists away form making absolute predictions to merely calculating the probability of an event. Quantum electrodynamics provides a method for doing this-drawing little arrows on a piece of paper. The probability of an event is represented by the area of the square of an arrow. For example, an arrow representing a probability of 0.04 (4%) has a length of 0.2. — Richard Feynman

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

Ancient wisdom and quantum physicists make unlikely bedfellows: In quantum mechanics the observer determines (or even brings into being) what is observed, and so, too, for the Tiwis, who dissolve the distinction between themselves and the cosmos. In quantum physics, subatomic particles influence each other from a distance, and this tallies with the aboriginal view, in which people, animals, rocks, and trees all weave together in the same interwoven fabric. — Huston Smith

Time is just an illusion. Einstein told us that. If this is the first time you have heard it, you may find it a hard concept to get your head around, because you see everything happening - one thing after the other. What quantum physicists and Einstein tell us is that everything is happening simultaneously. If you can understand that there is no time, and accept that concept, then you will see that whatever you want in the future already exists. If everything is happening at the one time, then the parallel version of you with what you want already exists! It takes no time for the Universe to manifest what you want. Any time delay you experience is due to your delay in getting to the place of believing, knowing, and feeling that you already have it. It is you getting yourself on the frequency of what you want. When you are on that frequency, then what you want will appear. — Rhonda Byrne

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

Bohm's interpretation of quantum physics indicated that at the subquantum level, the level in which the quantum potential operated, location ceased to exist. All points in space became equal to all other points in space, and it was meaningless to speak of anything as being separate from anything else. Physicists call this property 'nonlocality.' — Chuck Missler

I'm really fascinated by the parallels between quantum theory and the teachings of some of these ancient texts. So many of the things that quantum physicists are talking about today, like nonlocality and the observer effect, are things the yogis have been saying for thousands of years. — Beryl Bender Birch

Has anyone provided proof of God's inexistence? Not even close. Has quantum cosmology explained the emergence of the universe or why it is here? Not even close. Have our sciences explained why our universe seems to be fine-tuned to allow for the existence of life? Not even close. Are physicists and biologists willing to believe in anything so long as it is not religious thought? Close enough. Has rationalism and moral thought provided us with an understanding of what is good, what is right, and what is moral? Not close enough. Has secularism in the terrible 20th century been a force for good? Not even close, to being close. Is there a narrow and oppressive orthodoxy in the sciences? Close enough. Does anything in the sciences or their philosophy justify the claim that religious belief is irrational? Not even in the ball park. Is scientific atheism a frivolous exercise in intellectual contempt? Dead on. — David Berlinski

Physicists often quote from T. H. White's epic novel The Once and Future King , where a society of ants declares, 'Everything not forbidden is compulsory.' In other words, if there isn't a basic principle of physics forbidding time travel, then time travel is necessarily a physical possibility. (The reason for this is the uncertainty principle. Unless something is forbidden, quantum effects and fluctuations will eventually make it possible if we wait long enough. Thus, unless there is a law forbidding it, it will eventually occur.) — Michio Kaku

In quantum physics, the study of material at the subatomic level, you get down to the tiniest levels. When they take these subatomic particles, put them in particle accelerators and collide them, quantum physicists discover there's nothing there. There's no one home - no ghost in the machine. — Wayne Dyer

My experience has been that times always ends. In theory, you are right, the quantum physicists are right, the religious and romantics are right. Time without end. In practice we both wear a watch. — Jeanette Winterson

What those two young physicists did remains the most important step yet made in the search for quantum gravity. They gave us two general and simple laws, which were the first physical predictions to come from the study of quantum gravity. They are: Unruh's law. Accelerating observers see themselves as embedded in a gas of hot photons at a temperature proportional to their acceleration. Bekenstein's law With every horizon that forms a boundary separating an observer from a region which is hidden from them, there is associated an entropy which measures the amount of information which is hidden behind it. This entropy is always proportional to the area of the horizon. — Lee Smolin

The strength of the familiar electromagnetic force between two electrons, for example, is expressed in physics in terms of a constant known as the fine structure constant. The value of this constant, almost exactly 1/137, has puzzled many generations of physicists. A joke made about the famous English physicist Paul Dirac (1902-1984), one of the founders of quantum mechanics, says that upon arrival to heaven he was allowed to ask God one question. His question was: "Why 1/137? — Mario Livio

Physics is an otherworld thing, it requires a taste for things unseen, even unheard of- a high degree of abstraction ... These faculties die off somehow when you grow up ... profound curiosity happens when children are young. I think physicists are the Peter Pans of the human race ... Once you are sophisticated, you know too much- far too much. Pauli once said to me, "I know a great deal. I know too much. I am a quantum ancient.". — Isidor Isaac Rabi

She figured that the main problem in physics is physicists, that most of them are caught in a mind trap because they're so used to things being made of smaller things. So they instinctively believe that reality, at its most basic level, must be made up of and regulated by almost infinitely small elementary particles. — Rajnar Vajra

The verbal interpretation, on the other hand, i.e. the metaphysics of quantum physics, is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model. — Erwin Schrodinger

Up until now quantum entanglement has generally been considered limited to very small microscopic objects, such as subatomic particles, atoms, isolated molecules, and microscopic crystalline structures. In December 2011 a group of physicists from the University of Oxford, the National Research Council of Canada, and the National University of Singapore announced the successful quantum entanglement, using lasers, of oscillation patterns of atoms in two macroscopic (approximately 3 millimeters in size) diamonds at room temperature and separated by a distance of about 15 centimeters — Robert M. Schoch

[On the practical applications of particle physics research with the Large Hadron Collider.]
Sometimes the public says, 'What's in it for Numero Uno? Am I going to get better television reception? Am I going to get better Internet reception?' Well, in some sense, yeah ... All the wonders of quantum physics were learned basically from looking at atom-smasher technology ... But let me let you in on a secret: We physicists are not driven to do this because of better color television ... That's a spin-off. We do this because we want to understand our role and our place in the universe. — Michio Kaku

In Keynes's time, physicists were first grappling with the concept of quantum mechanics, which, among other things, imagined a cosmos governed by two entirely different sets of physical laws: one for very small particles, like protons and electrons, and another for everything else. Perhaps sensing that the boring study of economics needed a fresh shot in the arm, Keynes proposed a similar world view in which one set of economic laws came in to play at the micro level (concerning the realm of individuals and families) and another set at the macro level (concerning nations and governments). — Peter D. Schiff

Recent scientific experiments in quantum physics have shed enormous light on how this world might function and have confirmed beliefs by early quantum physicists that light is not the fastest moving particle. That information at the quantum level passes instantaneously, and thus is infinitely faster. — Newton Fortuin

Quantum theory was split up into dialects. Different people describe the same experiences in remarkably different languages. This is confusing even to physicists. — David Finkelstein

Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain. — John Stewart Bell

With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation in the laws of quantum electrodynamics. — Richard P. Feynman

The law of attraction is the law of creation. Quantum physicists tell us that the entire Universe emerged from thought! — Rhonda Byrne

I am very excited about Quantum Forgiveness. The pioneers of quantum physics overturned and transcended Newtonian physics and the scientific method. Quantum physicists worked down to the smallest units and realized that everything they thought they knew about the world was not true. The world is about potentiality. In superposition, for example, things appear where we believe they will appear. And that is exciting because it is a science discovery that does not have to stay in the lab. It actually has everything to do with who we are. It is the gateway to our experience of being one with Source! — David Hoffmeister

Quantum mechanics is so counter-intuitive, physicists have never been able to come up with a comfortable picture of how it works. — Taner Edis

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

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

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

Trying to capture the physicists' precise mathematical description of the quantum world with our crude words and mental images is like playing Chopin with a boxing glove on one hand and a catcher's mitt on the other. — George Johnson

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

Through experiments over the past few decades physicists have discovered matter to be completely mutable into other particles or energy and vice-versa and on a subatomic level, matter does not exist with certainty in definite places, but rather shows 'tendencies' to exist. Quantum physics is beginning to realise that the Universe appears to be a dynamic web of interconnected and inseparable energy patterns. If the universe is indeed composed of such a web, there is logically no such thing as a part. This implies we are not separated parts of a whole but rather we are the Whole. — Barbara Brennan

One of the older professors in the department didn't find my talk very convincing and made sure that everyone in the room knew of his unhappiness. The next day he sent an e-mail around to the department faculty, which he was considerate enough to copy to me: Finally, the magnitude of the entropy of the universe as a function of time is a very interesting problem for cosmology, but to suggest that a law of physics depends on it is sheer nonsense. Carroll's statement that the second law owes its existence to cosmology is one of the dummest [sic] remarks I heard in any of our physics colloquia, apart from [redacted]'s earlier remarks about consciousness in quantum mechanics. I am astounded that physicists in the audience always listen politely to such nonsense. Afterwards, I had dinner with some graduate students who readily understood my objections, but Carroll remained adamant. I hope he reads this book. — Sean Carroll

How do fields express their principles? Physicists use terms like photons, electrons, quarks, quantum wave functions, relativity, and energy conservation. Astronomers use terms like planets, stars, galaxies, Hubble shift, and black holes. Thermodynamicists use terms like entropy, first law, second law, and Carnot cycle. Biologists use terms like phylogeny, ontology, DNA, and enzymes. Each of these terms can be considered to be the thread of a story. The principles of a field are actually a set of interwoven stories about the structure and behavior of field elements, the fabric of the multiverse. — Peter J. Denning

The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world. — Alain Aspect

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

Erwin Schrodinger has explained how he and his fellow physicists had agreed that they would report their new discoveries and experiments in quantum physics in the language of Newtonian physics. That is, they agreed to discuss and report the non-visual, electronic world in the language of the visual world of Newton. — Marshall McLuhan

Most 20th century academic physicists, and academia as a whole, simply did not want to touch the subject of consciousness. We have seen psychology grow up, and we've seen the development of neurophysiology and other much more sophisticated science, but only in the recent years have the tools of quantum mechanics been applied to anything representing human scale size. — Edgar Mitchell

The quantum entered physics with a jolt. It didn't fit anywhere; it made no sense; it contradicted everything we thought we knew about nature. Yet the data seemed to demand it ... The story of Werner Heisenberg and his science is the story of the desperate failures and ultimate triumphs of the small band of brilliant physicists who-during an incredibly intense period of struggle with the data, the theories, and each other during the 1920s-brought about a revolutionary new understanding of the atomic world known as quantum mechanics. — David C. Cassidy

It was the discovery of the quantum universe that changed everything, and that universe was so small and so dynamic that it could not be observed directly. Trying to explain their insights, scientists looked at the language of mysticism. At the subatomic level, the parallels between quantum reality and mysticism were striking. For example, the behavior of light: in some contexts it acted like a wave, in others like a particle. Could it be both? Physicists had no concept for grasping this, so they dispensed with Western logic and embraced paradox. (This is important, too, for the notion of vampires being both living and dead.) — Katherine Ramsland

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

Physicists traced the failure to the jitters of quantum uncertainty. Mathematical techniques had been developed for analyzing the jitters of the strong, weak, and electromagnetic fields, but when the same methods were applied to the gravitational field-a field that governs the curvature of spacetime itself-they proved ineffective. This left the mathematics saturated with inconsistencies such as infinite probabilities. — Brian Greene

Einstein and the Quantum is delightful to read, with numerous historical details that were new to me and cham1ing vignettes of Einstein and his colleagues. By avoiding mathematics, Stone makes his book accessible to general readers, but even physicists who are well versed in Einstein and his physics are likely to find new insights into the most remarkable mind of the modern era. — Daniel Kleppner

As we discussed in Chapter 7, we physicists still haven't found a mathematical structure that can describe all aspects of reality, including gravity, but so far, there's no indication that string theory or any of the other most actively pursued candidates for such a description are any less mathematical than quantum field theory. — Max Tegmark
