Electrodynamics Quotes & Sayings

Relativity. Gravity. Quantum. Electrodynamics. Evolution. Each of these theories is true, whether or not you believe in them. — Neil DeGrasse Tyson

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

It was an epiphany when I realized you don't have to call yourself a linguist, a translator, a poet. You can call yourself an artist and you can do all these things. — Jan Peacock

You wait. Everyone has an Antarctic. — Thomas Pynchon

On the Electrodynamics of Moving Bodies" Now let's look at how Einstein articulated all of this in the famous paper that the Annalen der Physik received on June 30, 1905. For all its momentous import, it may be one of the most spunky and enjoyable papers in all of science. Most of its insights are conveyed in words and vivid thought experiments, rather than in complex equations. There is some math involved, but it is mainly what a good high school senior could comprehend. "The whole paper is a testament to the power of simple language to convey deep and powerfully disturbing ideas," says the science writer Dennis Overbye. — Walter Isaacson

Willard Gibbs did for statistical mechanics and for thermodynamics what Laplace did for celestial mechanics and Maxwell did for electrodynamics, namely, made his field a well-nigh finished theoretical structure. — Robert Andrews Millikan

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

If you have bought one of those T-shirts with Maxwell's equations on the front, you may have to worry about its going out of style, but not about its becoming false. We will go on teaching Maxwellian electrodynamics as long as there are scientists. — Steven Weinberg

The attempts to try to represent the electric field as the motion of some kind of gear wheels, or in terms of lines, or of stresses in some kind of material have used up more effort of physicists than it would have taken simply to get the right answers about electrodynamics. It is interesting that the correct equations for the behavior of light were worked out by MacCullagh in 1839. But people said to him: 'Yes, but there is no real material whose mechanical properties could possibly satisfy those equations, and since light is an oscillation that must vibrate in something, we cannot believe this abstract equation business'. — Richard Feynman

In 1956, when I began doing theoretical physics, the study of elementary particles was like a patchwork quilt. Electrodynamics, weak interactions, and strong interactions were clearly separate disciplines, separately taught and separately studied. There was no coherent theory that described them all. — Sheldon Lee Glashow

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

QED [quantum electrodynamics] reduces ... "all of chemistry and most of physics," to one basic interaction, the fundamental coupling of a photon to electric charge. The strength of this coupling remains, however, as a pure number, the so-called fine-structure constant, which is a parameter of QED that QED itself is powerless to predict. — Frank Wilczek

Adolescence is not only an important period in life, but that it is the only period where one may speak of life in the full sense of the word. The attractile drives are unleashed around the age of thirteen, after which they gradually diminish, or rather they are resolved in models of behaviour which are, after all, only constrained forces. The violence of the initial explosion means that the outcome of the conflict may remain uncertain for years; this is what is called a transitory regime in electrodynamics. But little by little the oscillations become slower, to the point of resolving themselves in mild and melancholic long waves; from this moment on all is decided, and life is nothing more than a preparation for death. This can be expressed in a more brutal and less exact way by saying that man is a diminished adolescent. — Michel Houellebecq

That odd capacity for destitution, as if by nature we ought to have so much more than nature gives us. As if we are shockingly unclothed when we lack the complacencies of ordinary life. In destitution, even of feeling or purpose, a human being is more hauntingly human and vulnerable to kindnesses because there is the sense that things should be otherwise, and then the thought of what is wanting and what alleviation would be, and how the soul could be put at ease, restored. At home. But the soul finds its own home if it ever has a home at all. — Marilynne Robinson

I have lived a long life, and I have seen a few things. I walked away from the Last Great Time War. I marked the passing of the Time Lords. I saw the birth of the universe and I watched as time ran out, moment by moment, until nothing remained; no time, no space. Just me. I walked in universes where the laws of physics were devised by the mind of a madman. I watched universes freeze and creations burn. I have seen things you wouldn't believe, I have lost things you will never understand. And I know things, secrets that must never be told, knowledge that must never be spoken. Knowledge that will make parasite gods blaze! So come on then! Take it! Take it all, baby! Have it! You have it all! — Neil Cross

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation. — David Gross

The chance is high that the truth lies in the fashionable direction. But, on the off chance that it is in another direction - a direction obvious from an unfashionable view of field theory - who will find it? Only someone who has sacrificed himself by teaching himself quantum electrodynamics from a peculiar and unfashionable point of view; one that he may have to invent for himself. — Richard P. Feynman

I have no connection with Hollywood. I'm not interested. I don't care. — Adam Carolla

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

Even the young are killing each other. — Pope John Paul I

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

There were several possible solutions of the difficulty of classical electrodynamics, any one of which might serve as a good starting point to the solution of the difficulties of quantum electrodynamics. — Richard P. Feynman

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

From a long view of the history of mankind, seen from, say, ten thousand years from now, there can be little doubt that the most significant event of the 19th century will be judged as Maxwell's discovery of the laws of electrodynamics. The American Civil War will pale into provincial insignificance in comparison with this important scientific event of the same decade. — Richard Feynman

I have a problem with the way the House is run. I believe that a few people at the top of a pyramid of power have controlled this place for a long time. — Dan Webster

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
