Particle Theory Quotes & Sayings

Which is to say that culture is not a reflex of political economy, but
that society is now a reflex of key shifts in music theory and practice ...
[Sampladelia is] the sound made by those early-twentieth-century discoveries
in particle physics and relativiity theory, the projection of the minds of
Einstein, Heisenbery, and Bohr, their fateful explorations of liquid time,
curving space, uncertainty fields and relativity theorems, into densely
configured and fully ambivalent android music tracks — Arthur Kroker

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

In 2002, a Scottish journalist, during a dinner meant to be private, absolutely wanted me to react to Stephen Hawking's comments. I said one shouldn't pay too much attention to what Hawking was saying because he was a celebrity but not a specialist of elementary particle theory. — Peter Higgs

A bit, the smallest unit of information, the fundamental particle of information theory, is a choice, yes or no, on or off. It's a choice that you can embody in electrical circuits, and it is thanks to that that we have all this ubiquitous computing. — James Gleick

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

The full name of string theory is really superstring theory. The 'super' stands for this feature called supersymmetry, which, without getting into any details, predicts that for every known particle in the world, there should be a partner particle, the so-called supersymmetric partner. — Brian Greene

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory. — Richard P. Feynman

I started out working on supersymmetry. The theory predicts that for every particle we know about, there will be an additional particle. — Lisa Randall

An exciting feature of string theory is that the particles emerge from the theory itself: a distinct species of particle arises from each distinct string vibrational pattern. And since the vibrational pattern determines the properties of the corresponding particle, if you understood the theory well enough to delineate all vibrational patterns, you'd be able to explaine all properties of all particles. The potential and the promies, then, is that string theory will transcent quantum field theory by deriving all particle properties mathematically. Not only would this unify everything under the umbrella of vibrating strings, it would establish that future "surprises"-such as the discovery of currently unknown particle species-are built into string theory from the outset and so would be accessible, in principle, to sufficiently industrious calculation. String theory doesn't build piecemeal toward an ever more complete description of nature. It seeks a complete description from the get-go. — Brian Greene

We have one real candidate for changing the rules; this is string theory. In string theory the one-dimensional trajectory of a particle in spacetime is replaced by a two-dimensional orbit of a string. Such strings can be of any size, but under ordinary circumstances they are quite tiny, ... a value determined by comparing the predictions of the theory for Newton's constant and the fine structure constant to experimental values. — Edward Witten

I have a theory that evolutionary biologists are more vain than particle physicists. — Robin Ince

My colleagues in elementary particle theory in many lands [and I] are driven by the usual insatiable curiosity of the scientist, and our work is a delightful game. I am frequently astonished that it so often results in correct predictions of experimental results. How can it be that writing down a few simple and elegant formulae, like short poems governed by strict rules such as those of the sonnet or the waka, can predict universal regularities of Nature? — Murray Gell-Mann

Over the last three decades, theorists have proposed at least a dozen new approaches. Each approach is motivated by a compelling hypothesis, but none has so far succeeded. In the realm of particle physics, these include Technicolor, preon models, and supersymmetry. In the realm of spacetime, they include twistor theory, causal sets, supergravity, dynamical triangulations, and loop quantum gravity. Some of these ideas are as exotic as they sound. — Lee Smolin

We are a manifestation that we perpetuate through space-time. Death is the ceasing of the observation of it whether by direct or indirect influence. — Solange Nicole

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string. — Edward Witten

The Z-particle Pure energy - no mass at all. It may well be the
smallest building block in nature. Matter is nothing but trapped energy. — Dan Brown

Is the universe 'elegant,' as Brian Greene tells us? Not as far as I can tell, not the usual laws of particle physics, anyway. I think I might find the universal principles of String Theory most elegant - if I only knew what they were. — Leonard Susskind

The progress of the sciences toward theories of fundamental unity, cosmic symmetry (as in the unified field theory) - how do such theories differ, in the end, from that unity which Plato called "unspeakable" and "indiscribable," the holistic knowledge shared by so many peoples of the earth, Christians included, before the advent of the industrial revolution made new barbarians of the peoples of the West? In the United States, before spiritualist foolishness at the end of the last century confused mysticism with "the occult" and tarnished both, William James wrote a master work of metaphysics; Emerson spoke of "the wise silence, the universal beauty, to which every part and particle is equally related, the eternal One . . ."; Melville referred to "that profound silence, that only voice of God"; Walt Whitman celebrated the most ancient secret, that no God could be found "more divine than yourself. — Peter Matthiessen

Banishing zero also solves the infinity problems in general relativity. If you imagine a black hole as a string, no longer do objects fall through a rip in the fabric of space-time. Instead, a particle loop approaching a black-hole loop stretches out and touches the black hole. The two loops tremble, tear, and form one loop: a slightly more massive black hole. (Some theorists believe that the act of merging a particle to a black hole creates bizarre particles such as tachyons: particles with imaginary mass that travel backward in time and move faster than light. Such particles might be admissable in certain versions of string theory.) — Charles Seife

Lecter sits in his armchair with a big pad of butcher paper doing calculations. The pages are filled with the symbols both of astrophysics and particle physics. There are repeated efforts with the symbols of string theory. The few mathematicians who could follow him might say his equations begin brilliantly and then decline, doomed by wishful thinking. Dr. Lecter wants time to reverse - no longer should increasing entropy mark the direction of time. He wants increasing order to point the way. — Thomas Harris

Now, from special relativity we know that energy and mass are two sides of the same coin: Greater energy means greater mass, and vice versa. Thus, according to string theory, the mass of an elementary particle is determined by the energy of the vibrational pattern of its internal string. Heavier particles have internal strings that vibrate more energetically, while lighter particles have internal strings that vibrate less energetically. — Brian Greene

Supersymmetry is a theory which stipulates that for every known particle there should be a partner particle. For instance, the electron should be paired with a supersymmetric 'selectron,' quarks ought to have 'squark' partners, and so on. — Brian Greene

Reality is what kicks back when you kick it. This is just what physicists do with their particle accelerators. We kick reality and feel it kick back. From the intensity and duration of thousands of those kicks over many years, we have formed a coherent theory of matter and forces, called the standard model, that currently agrees with all observations. — Victor J. Stenger

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

If Feynman could see beauty as the inspiration for the theory of the rainbow, and if an electron could behave like a wave, and light like a particle, then the little contradiction of Leonard flitting among different subfields of physics, or even among varied careers, would not shake the universe. — Anonymous

Consider the enormity of the problem. Science has proved that the universe exploded into being at a certain moment. It asks: What cause produced this effect? Who or what put the matter or energy into the universe? And science cannot answer these questions, because, according to the astronomers, in the first moments of its existence the Universe was compressed to an extraordinary degree, and consumed by the heat of a fire beyond human imagination. The shock of that instant must have destroyed every particle of evidence that could have yielded a clue to the cause of the great explosion. — Robert Jastrow

So far Unitarian realism claiming to possess positive knowledge about Ultimate Reality has succeeded only by excluding large areas of phenomena or by declaring, without proof, that they could be reduced to basic theory, which, in this connection, means elementary particle physics. — Paul Feyerabend

Indeed, the history of 20th century physics was in large measure about how to avoid the infinities that crop up in particle theory and cosmology. The idea of point particles is convenient but leads to profound, puzzling troubles. — Gregory Benford

I think also of my colleagues in elementary particle theory in many lands, and feel that in some measure I am here as a representative of our small, informal, international fraternity. — Murray Gell-Mann

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

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

The importance of group theory was emphasized very recently when some physicists using group theory predicted the existence of a particle that had never been observed before, and described the properties it should have. Later experiments proved that this particle really exists and has those properties. — Irving Adler

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

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

According to string theory, if we could examine these particles with even greater precision - a precision many orders of magnitude beyond our present technological capacity - we would find that each is not pointlike, but instead consists of a tiny one-dimensional loop. Like an infinitely thin rubber band, each particle contains a vibrating, oscillating, dancing filament that physicists, lacking Gell-Mann's literary flair, have named a string. — Brian Greene
