Physics Quotes

In some sense, gravity does not exist; what moves the planets and the stars is the distortion of space and time.

The history of atomism is one of reductionism – the effort to reduce all the operations of nature to a small number of laws governing a small number of primordial objects.

Leon M. Lederman

For [Wolfgang] Pauli the central problem of electrodynamics was the field concept and the existence of an elementary charge which is expressible by the fine-structure constant ... 1/137. This fundamental pure number had greatly fascinated Pauli, .... For Pauli the explanation of the number 137 was the test of a successful field theory, a test which no theory has passed up to now.

Charles P. Enz

It will reward enough for me if, by the publication of the present experiment, I have directed the attention of investigators to this subject, which still promises much for physical optics and appears to open a new field.

Joseph von Fraunhofer

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

Tapestries are made by many artisans working together. The contributions of separate workers cannot be discerned in the completed work, and the loose and false threads have been covered over. So it is in our picture of particle physics.

Sheldon L. Glashow

It has today occurred to me that an amplifier using semiconductors rather than vacuum is in principle possible.[Laboratory notebook, 29 Dec 1939.]

William Shockley

At his "World of Physics" Web site, Eric W. Weisstein notes that the fine structure constant continues to fascinate numerologists, who have claimed that connections exist between alpha, the Cheops pyramid, and Stonehenge!

Clifford A. Pickover

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

Very high altitude astronomy only works by ignoring established biological science

Steven Magee

Following the path of earlier unificationists, one of Eddington's aims was to reduce the contingencies in the description of nature, for example, by explaining the fundamental constants of physics rather than accepting them as merely experimental data. One of these constants was the fine-structure constant ..., which entered prominently in Dirac's theory and was known to be about 1/137.

Helge Kragh

God is a pure mathematician!' declared British astronomer Sir James Jeans. The physical Universe does seem to be organised around elegant mathematical relationships. And one number above all others has exercised an enduring fascination for physicists: 137.0359991.... It is known as the fine-structure constant and is denoted by the Greek letter alpha (α).

Paul Davies

Don't confound static electricity with ecstatic eccentricity. One will leave your hair up, the other will live up in the air!

Ana Claudia Antunes

The velocities and forces involved in anything at orbital altitudes were enough to kill a human with just the rounding error. At their speeds, the friction from air too thin to breathe would set them on fire.

James S.A. Corey

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

Quite obviously, a theoretical determination of the numerical value of α would signify great progress in our understanding of fundamental interactions. Many physicists have tried to find it, but without significant success to this day. Richard Feynman, the theory wizard of Caltech in Pasadena, once suggested that every one of his theory colleagues should write on the blackboard in his office: 137 -- how shamefully little we understand!

Harald Fritzsch

True, the Standard Model does explain a very great deal. Nevertheless it is not yet a proper theory, principally because it does not satisfy the physicists naive faith in elegance and simplicity. It involves some 17 allegedly fundamental particles and the same number of arbitrary and tunable parameters, such as the fine-structure constants, the muon-electron mass ratio and the various mysterious mixing angles.

Sheldon L. Glashow

George Malcolm: half white, half black, with messy tousled hair, rumpled and tugged between kind of curly and extremely curly. Once, a year or so before, he'd been at our house and he'd pulled out a lock of his hair and used it to teach me about eddies and helixes. It's a circular current into a central station, he'd explained, giving me one to hold. I pulled on the spring. Nature is full of the same shapes, he said, taking me to the bathroom sink and spinning on the top and pointing out the way the water swirled down the drain. Taking me to the bookshelf and flipping open a book on weather and showing me a cyclone. Then a spiral galaxy. Pulling me back to the bathroom sink, to my glass jar of collected seashells, and pointing out the same curl in a miniature conch. See? he said, holding the seashell up to his hair. Yes! I clapped. His eyes were warm with teaching pleasure. It's galactic hair, he said, smiling.At school, George was legendary already. He was so natural at physics that one afternoon the eighth-grade science teacher had asked him to do a preview of the basics of relativity, really fast, for the class. George had stood up and done such a fine job, using a paperweight and a yardstick and the standard-issue school clock, that the teacher had pulled a twenty-dollar bill from his wallet. I'd like to be the first person to pay you for your clarity of mind, the teacher had said. George used the cash to order pizza for the class. Double pepperoni, he told me later, when I'd asked.

Aimee Bender

Highly complex numbers like the Comma of Pythagoras, Pi and Phi (sometimes called the Golden Proportion), are known as irrational numbers. They lie deep in the structure of the physical universe, and were seen by the Egyptians as the principles controlling creation, the principles by which matter is precipitated from the cosmic mind.Today scientists recognize the Comma of Pythagoras, Pi and the Golden Proportion as well as the closely related Fibonacci sequence are universal constants that describe complex patterns in astronomy, music and physics. ...To the Egyptians these numbers were also the secret harmonies of the cosmos and they incorporated them as rhythms and proportions in the construction of their pyramids and temples.

Jonathan Black

The prime number 137 had continuously occupied Pauli's mind. It is an approximate value for a constant appearing in the fine structure theory of atomic spectra which in its theoretical expression ties together electromagnetism, relativity and quantum theory. Pauli saw the fine structure theory of spectra as a key in understanding the deepest contemporary problems of theoretical physics. For that reason the number 137 possessed a mysterious attraction for him.

K. V. Laurikainen

The release of atomic power has changed everything except our way of thinking ... the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker. (1945)

Albert Einstein

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

It did not last: the Devil howling 'Ho, Let Einstein be,' restored the status quo.

John Collings Squire

The claim that the universe *began* with the big bang has no basis in current physical and cosmological knowledge. The observations confirming the big bang do not rule out the possibility of a prior universe.

Victor J. Stenger

I believe that this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth.

John F Kennedy

...Why is it, that from the moment you enter medical school to the moment you retire, that the only disorder you will ever diagnosis with a physics book - is obesity? This is biology folks, it's endocrinology, it's physiology - physics has nothing to do with it. The law of thermodynamics is always true, [but] the energy balance equation is irrelevant...

Gary Taubes

The particles that are the very building blocks of all things, are in all possible locations until observation/measurement causes them to choose a specific position.

Kevin Michel

There are over a million types of fish in the sea as there are flowers in all of the world's gardens. There are at least a million different types of minerals as there are species of birds or monkeys. The possible configurations of lifeforms that could be created from a single atom are infinite. There are at least a billion people on this earth, and no two faces look the same. It is very arrogant to assume that we have seen all of God's miracles.

Suzy Kassem

In a nice little house in Atro City there lived a man called Doktor Gleichstein. He was a kind of scientist, and he was very good at his job, which is why he always worked from home. He looked a little funny because he kept losing his eyebrows. Quantum Physics, is sort of like ordinary Physics, only you tend to spend a lot more time looking for the cat. He worked in the sitting room because he’d blown the garage up once already. Apparently a lot of things happened by accident in Quantum Physics.

Christina Engela

The Hartle-Hawking derivation of the unconditional probability of the existence of a universe of our sort is inconsistent with classical theism. The unconditional probability is very high, near to 1. For purposes of simplification, we are saying the probability is 99 percent; there is a 99 percent probability that a universe of our sort—I will call it a Hartle-Hawking universe—exists uncaused.The universe exists uncaused since the probability amplitude is determined by a summation or path integral over all possible histories of a finite universe. That is, the probability that a Hartle-Hawking universe exists follows directly from the natural-mathematical properties of possible finite universes; there is no need for a cause, probabilistic or otherwise, for there to be a 99 percent probability that a Hartle-Hawking universe will exist.This is not consistent with classical theism. According to classical theism, if a universe is to have any probability of existing, this probability is dependent on God's dispositions, beliefs, or choices. But the Hartle-Hawking probability is not dependent on any supernatural states or acts; Hartle and Hawking do not sum over anything supernatural in their path integral derivation of the probability amplitude.Furthermore, according to classical theism, the probability that a universe exist without divine causation is 0, and the probability that if a universe exists, it is divinely caused, is 1. Thus, the probabilities that are implied by classical theism are inconsistent with the probabilities implied by the Hartle-Hawking wave function of the universe.

Quentin Smith

But every day I go to work I'm making a bet that the universe is simple, symmetric, and aesthetically pleasing—a universe that we humans, with our limited perspective, will someday understand.

George Smoot

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

Thus identified with astronomy, in proclaiming truths supposed to be hostile to Scripture, Geology has been denounced as the enemy of religion. The twin sisters of terrestrial and celestial physics have thus been joint-heirs of intolerance and persecution—unresisting victims in the crusade which ignorance and fanaticism are ever waging against science. When great truths are driven to make an appeal to reason, knowledge becomes criminal, and philosophers martyrs. Truth, however, like all moral powers, can neither be checked nor extinguished. When compressed, it but reacts the more. It crushes where it cannot expand—it burns where it is not allowed to shine. Human when originally divulged, it becomes divine when finally established. At first, the breath of a rage—at last it is the edict of a god. Endowed with such vital energy, astronomical truth has cut its way through the thick darkness of superstitious times, and, cheered by its conquests, Geology will find the same open path when it has triumphed over the less formidable obstacles of a civilized age.

David Brewster

Metaphysics is not the result of understanding the limitations of physics.It’s rather the result of the limitation in understanding physics.

M.R. Shabanali

Is the purpose of theoretical physics to be no more than a cataloging of all the things that can happen when particles interact with each other and separate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?

Julian Schwinger

Leonardo believed his research had thepotential to convert millions to a more spiritual life. Last year he categorically proved the existence ofan energy force that unites us all. He actually demonstrated that we are all physically connected… thatthe molecules in your body are intertwined with the molecules in mine… that there is a single forcemoving within all of us.” Langdon felt disconcerted. And the power of God shall unite us all. “Mr. Vetra actually found a wayto demonstrate that particles are connected?”“Conclusive evidence. A recent Scientific American article hailed New Physics as a surer path to Godthan religion itself.

Mister Geoffrey, my experiment shows that the dynamo and the bulb are both working properly," I said. "So why won't the radio play?""I don't know," he said. "Try connecting them here."He was pointing toward a socket on the radio labeled "AC," and when I shoved the wires inside, the radio came to life. We shouted with excitement. As I pedaled the bicycle, I could hear the great Billy Kaunda playing his happy music on Radio Two, and that made Geoffrey start to dance."Keep pedaling," he said. "That's it, just keep pedaling.""Hey, I want to dance, too.""You'll have to wait your turn."Without realizing it, I'd just discovered the difference between alternating and direct current. Of course, I wouldn't know what this meant until much later.After a few minutes of pedaling this upside-down bike by hand, my arm grew tired and the radio slowly died. So I began thinking, "What can do the pedaling for us so Geoffrey and I can dance?

MUSIC OF THE UNIVERSEWithout the orchestra of the universe,There would be no ether. And without its instrumentationBy the ether, There would be no waves. And without any waves, There would be no sound. And without sound, There would be no music. And without music, There would be no life. And without a life force, There would be no matter. But it does not matter - Because what is matter, If there is no light?

Number ... should not be understood solely as a construction of consciousness, but also as an archetype and thus as a constituent of nature both without and within.

Abhijit Naskar

The fine-structure constant is ubiquitous throughout physics. I’ve already noted its connection to the electromagnetic interaction. In atomic physics, the binding energy, fine-structure splitting, and Lamb shift are all proportional to powers of α. In condensed matter physics, α characterizes Josephson junction oscillations and quantum Hall resistance steps. In addition, α is an important component of our system of fundamental constants. [Physics Today]

Gerald Gabrielse

… there are no arbitrary constants ... nature is so constituted that it is possible logically to lay down such strongly determined laws that within these laws only rationally determined constants occur (not constants, therefore, whose numerical value could be changed without destroying the theory).

Albert Einstein

If and when all the laws governing physical phenomena are finally discovered, and all the empirical constants occurring in these laws are finally expressed through the four independent basic constants, we will be able to say that physical science has reached its end, that no excitement is left in further explorations, and that all that remains to a physicist is either tedious work on minor details or the self-educational study and adoration of the magnificence of the completed system. At that stage physical science will enter from the epoch of Columbus and Magellan into the epoch of the National Geographic Magazine!

Same as you, Arthur. I hitched a ride. After all, with a degree in maths and another in astrophysics it was either that or back to the dole queue on Monday. Sorry I missed the Wednesday lunch date, but I was in a black hole all morning.

Douglas Adams

... who can forget the amazement of a child balancing an adult on a see-saw, simply by being placed at the right position. How could this be? Where did all that extra force come from!?The only wonder nowadays is that a physics student is unlikely to produce a satisfactory answer to this question. Perhaps we will be offered a few mumblings about moments, force times distance, laws of the lever perhaps even the "principle of virtual work". But we probably won't get an answer that seems to explain where that extra force comes from; and it is highly unlikely that we will get an answer that begins by establishing principles about rigid bodies, even though the rigidity of the lever is an absolute necessity for it to work.In fact, the whole path from Newton's Laws, which basically concern "point masses", to bodies whose shape and extent are significant, is often rather dubiously traversed, even though elementary physics courses blithely pose such problems of the most diverse sorts.

Credentials are like potential energy, the compliments of a name on paper, in documents, word of mouth, but faith is like kinetic energy, the motion and the force that which is witnessed. Hence in the end it is the faith rather than the credentials that really takes you places.

Criss Jami

Everything turns in circles and spirals with the cosmic heart until infinity. Everything has a vibration that spirals inward or outward — and everything turns together in the same direction at the same time. This vibration keeps going: it becomes born and expands or closes and destructs — only to repeat the cycle again in opposite current. Like a lotus, it opens or closes, dies and is born again. Such is also the story of the sun and moon, of me and you. Nothing truly dies. All energy simply transforms.
