Quotes & Sayings About Electromagnetism

If the hand be held between the discharge-tube and the screen, the darker shadow of the bones is seen within the slightly dark shadow-image of the hand itself ... For brevity's sake I shall use the expression 'rays'; and to distinguish them from others of this name I shall call them 'X-rays'. — Wilhelm Conrad Rontgen

The accumulated knowledge of materials, computing, electromagnetism, product design, and all the rest that we've learned over the last several centuries converts a few ounces of raw materials worth mere pennies into a device with more computing power than the entire planet possessed fifty years ago. — Ramez Naam

As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore. — Edward Witten

Our deepest description of physical reality, in quantum theory and in the four Core Theories of forces (gravitation, electromagnetism, strong and weak forces), bring in concepts that call to mind yin and yang. Niels Bohr, an influential founder of quantum theory, saw strong parallels between his concept of complementarity and the unified duality of yin-yang. He designed a coat of arms for himself, in which the yin-yang figures centrally (see figure 42, page 324). Our Core Theories center on the interplay between lightlike space filling fluids (yang) and substances (yin) they both direct and respond to. — Frank Wilczek

Light brings us the news of the Universe. — William Henry Bragg

I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper ...
The effect was one which could only be produced in ordinary parlance by the passage of light. No light could come from the tube because the shield which covered it was impervious to any light known even that of the electric arc ...
I did not think I investigated ...
I assumed that the effect must have come from the tube since its character indicated that it could come from nowhere else ... It seemed at first a new kind of invisible light. It was clearly something new something unrecorded ...
There is much to do, and I am busy, very busy.
[Describing to a journalist the discovery of X-rays that he had made on 8 Nov 1895.] — Wilhelm Conrad Rontgen

At one point in the story, following a brazen daytime bank robbery, Electro is shown escaping from the authorities by climbing up the side of a building, as easily as Spider-Man . . . we see one observer exclaim, "Look!! That strangely-garbed man is racing up the side of the building!" A second man on the street picks up the narrative: "He's holding on to the iron beams in the building by means of electric rays - using them like a magnet!! Incredible!"

There are three feelings inspired by this scene. The first is wonder as to why people rarely use the phrase "strangely-garbed" anymore. The second is nostalgia for the bygone era when pedestrians would routinely narrate events occurring in front of them, providing exposition for any casual bystander. And the third is pleasure at the realization that Electro's climbing this building is actually a physically plausible use of his powers. — James Kakalios

Way back in 1831, Michael Faraday, one of the founders of our modern understanding of electromagnetism, was asked by an inquiring politician about the usefulness of this newfangled "electricity" stuff. His apocryphal reply: "I know not, but I wager that one day your government will tax it". — Sean Carroll

Michael Faraday demonstrated that if you push a magnet through a coil of wire, an electric current flows. Conversely, if you pass an electric current through a wire it can deflect a nearby magnetic compass. From this, Faraday deduced that electric currents create magnetic fields, and moving magnetic fields create electric currents. Thus was electromagnetism discovered, unifying electricity and magnetism. — Andrew Thomas

Surprisingly now, over a half a century later, time symmetric approaches to electromagnetism, quantum mechanics, gravity, and cosmology might be consonant with the kind of eschatology that a theist such as Pannenberg supports. — Robert John Russell

Planck ... and Bohr ... have invented systems containing electrons of which the motion produces no effect upon external charges ... [N]ot only [is this] inconsistent with the accepted laws of electromagnetism, but I may add, is logically objectionable, for that state of motion which produces no physical effect whatsoever may better be called a state of rest. — G.N.Lewis

No space, no time, no gravity, no electromagnetism, no particles. Nothing. We are back where Plato, Aristotle and Parmenides struggled with the great questions: How Come the Universe, How Come Us, How Come Anything? But happily also we have around the answer to these questions. That's us. — John Archibald Wheeler

Maxwell's theory of electromagnetism is generally studied only by advanced students of physics, but Albert had mastered it by the time he was sixteen years old. — Robert Cwiklik

Laplace's Demon, the hypothetical imp that knows the instantaneous positions and velocities of every particle in the universe, was said to be able to calculate the entire future or past by plugging these values into the equations that express the laws of mechanics and electromagnetism. — Steven Pinker

Faraday is, and must always remain, the father of that enlarged science of electromagnetism. — James Clerk Maxwell

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

The forces that govern our experience, electromagnetism and gravity, are blind to the distinction between left and right. No process moderated by either force can turn something such as your right hand into its mirror image. I cannot — Lawrence M. Krauss

It required unusual inquisitiveness to pursue the development of scientific curiosities such as charged pith balls, the voltaic cell, and the electrostatic machine. Without such endeavors and the evolution of associated instrumentation, initially of purely scientific interest, most of the investigations that lead to the basic equations of electromagnetism would have been missed ... We would have been deprived of electromagnetic machinery as well as knowledge of electromagnetic waves. — Frederick Seitz

The fine structure constant is undoubtedly the most fundamental pure (dimensionless) number in all of physics. It relates the basic constants of electromagnetism (the charge of the electron), relativity (the speed of light), and quantum mechanics (Planck's constant). — David J. Griffiths

Kaluza revealed that in a universe with an additional dimension of space, gravity and electromagnetism can both be described in terms of spatial ripples. Gravity ripples through the familiar three spatial dimensions, while electromagnetism ripples through the fourth. An outstanding problem with Kaluza's proposal was to explain why we don't see this fourth spatial dimension. It was here that Klein made his mark by suggesting the resolution explained above: dimensions beyond those we directly experience can elude our senses and our equipment if they're sufficiently small. — Brian Greene

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

Faraday has the Cage, Tesla has the Coil and Magee has the Sandwich! — Steven Magee

The focus of history and philosophy of science scholar Arthur Miller's (2010) "137: Jung and Pauli and the Pursuit of Scientific Obsession" is Jung and Pauli's
mutual effort to discover the cosmic number or fine structure constant, which is a fundamental physical constant dealing with electromagnetism, or, from a different perspective, could be considered the philosopher's stone of the mathematical universe.
This was indeed one of Pauli and Jung's collaborative passions, but it was not the only concentration of their relationship. Quantum physics could be seen as the natural progression from ancient alchemy, through chemistry, culminating in the abstract world of subatomic particles, wave functions, and mathematics. [Ancient Egypt and Modern Psychotherapy] — Todd Hayen

The brain, which operates on electromagnetic impulses, is as much an activity of the universe as are the electromagnetic storms in the atmosphere or on a distant star. Therefore science is one form of electromagnetism that spends it time studying another form ... science is god explaining god through a human nervous system ... isn't spirituality the same thing? — Deepak Chopra

The importance of C.F. Gauss for the development of modern physical theory and especially for the mathematical fundament of the theory of relativity is overwhelming indeed; also his achievement of the system of absolute measurement in the field of electromagnetism. In my opinion it is impossible to achieve a coherent objective picture of the world on the basis of concepts which are taken more or less from inner psychological experience. — Albert Einstein
