Electromagnetic Theory Of Light Quotes

Religious creeds are a great obstacle to any full sympathy between the outlook of the scientist and the outlook which religion is so often supposed to require ... The spirit of seeking which animates us refuses to regard any kind of creed as its goal. It would be a shock to come across a university where it was the practice of the students to recite adherence to Newton's laws of motion, to Maxwell's equations and to the electromagnetic theory of light. We should not deplore it the less if our own pet theory happened to be included, or if the list were brought up to date every few years. We should say that the students cannot possibly realise the intention of scientific training if they are taught to look on these results as things to be recited and subscribed to. Science may fall short of its ideal, and although the peril scarcely takes this extreme form, it is not always easy, particularly in popular science, to maintain our stand against creed and dogma. ~ Arthur Stanley Eddington

Even in the darkest of times we have the right to expect some illumination, and ... such illumination may well come less from theories and concepts than from the uncertain, flickering, and often weak light that some men and women, in their lives and their works, will kindle under almost all circumstances and shed over the time-span that was given them on earth ... ~ Hannah Arendt

I joined the Army and was sent to the MIT radiation laboratory after a few months of introduction to electromagnetic wave theory in a special course, given for Army personnel at the University of Chicago. ~ Jack Steinberger

We have already seen that gauge symmetry that characterizes the electroweak force-the freedom to interchange electrons and neturinos-dictates the existence of the messenger electroweak fields (photon, W, and Z). Similarly, the gauge color symmetry requires the presence of eight gluon fields. The gluons are the messengers of the strong force that binds quarks together to form composite particles such as the proton. Incidentally, the color "charges" of the three quarks that make up a proton or a neutron are all different (red, blue, green), and they add up to give zero color charge or "white" (equivalent to being electrically neutral in electromagnetism). Since color symmetry is at the base of the gluon-mediated force between quarks, the theory of these forces has become known as quantum chromodynamics. The marriage of the electroweak theory (which describes the electromagnetic and weak forces) with quantum chromodynamics (which describes the strong force) produced the standard model-the basic theory of elementary particles and the physical laws that govern them. ~ Mario Livio

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

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

Do you suppose it's so much easier to make conversation with someone you already know well than with someone you don't know at all primarily because of all the previously exchanged information and shared experiences between two people who know each other well, or because maybe it's only with people we already know well and know know us well that we don't go through the awkward mental process of subjecting everything we think of saying or bringing up as a topic of light conversation to a self-conscious critical analysis and evaluation that manages to make anything we think of proposing to say the other person seem dull or stupid or banal or on the other hand maybe overly intimate or tension-producing? ~ David Foster Wallace

Chris hurried after him. 'It's so hard to believe we just travelled hundreds of light years.'
'Why?' asked the Doctor.
'I always understood that you cannot travel faster than light,' said Chris.
'Says who?'
'Says Einstein,' said Chris.
'What?' The Doctor stopped and put an arm around Chris's shoulder. 'Do you understand Einstein?'
Chris wasn't sure where this was going. 'Yes.'
'What?' gasped the Doctor. 'And quantum theory?'
'Yes,' said Chris. He basked in the Doctor's astonishment, on firmer ground at last.
'What?' gasped the Doctor. 'And Planck?'
'Yes,' said Chris.
'What?' gasped the Doctor. 'And Newton?'
'Yes!' said Chris.
'What?' gasped the Doctor. 'And Schoenberg?'
Chris paused. Was it a trick question? He recalled reading about the crisis of tonality. He thought he'd caught most of it, so he answered proudly, 'Yes. Of course.'
The Doctor whistled, apparently impressed. Then he said, 'You've got an awful lot to unlearn, Bristol. ~ Gareth Roberts

One of my hobbies is discovering Universal laws. Here's one: if you light a cigarette, the bus always comes immediately. I have tested this theory many years, its a golden rule. If you light the cigarette, the bus ALWAYS comes. ~ Martijn Benders

But if it be true, as every prospect assures us, that the human race shall not again relapse into its ancient barbarity; if every thing ought to assure us against that pusillanimous and corrupt system which condemns man to eternal oscillations between truth and falsehood, liberty and servitude, we must, at the same time, perceive that the light of information is spread over a small part only of our globe; and the number of those who possess real instruction, seems to vanish in the comparison with the mass of men consigned over to ignorance and prejudice. We behold vast countries groaning under slavery, and presenting nations in one place, degraded by the vices of civilization, so corrupt as to impede the progress of man; and in others, still vegetating in the infancy of its early age. We perceive that the exertions of these last ages have done much for the progress of the human mind, but little for the perfection of the human species; much for the glory of man, somewhat for his liberty, but scarcely any thing yet for his happiness. In a few directions, our eyes are struck with a dazzling light; but thick darkness still covers an immense horison. ~ Nicolas De Condorcet

Evolution throws a wonderful light on all the struggles, eccentricities, tortuous developments of the human conscience in the past. It is the only theory of morals that does. And evolution throws just as much light on the ethical and social struggle today; and it is the only theory that does. What a strange age ours is from the religious point of view! What a hopeless age from the philosopher's point of view! Yet it is a very good age, the best that ever was. No evolutionist is a pessimist. ~ Joseph McCabe

Such abstraction which refuses to accept the given universe of facts as the final context of validation, such "transcending" analysis of the facts in the light of their arrested and denied possibilities, pertains to the very structure of social theory. ~ Herbert Marcuse

When I was younger I thought going through something rough would be fun, or uplifting somehow. That sounds odd, but it was how everyone portrayed terrible things. You go through this horrid experience, and suddenly you're a better person. I wanted that; everyone wants to be a better person.
Now, though, after all of this, I realized that wasn't true. Not all the time, at least. Suffering didn't make a person stronger. It didn't make character, or mold someone into a better part of themselves.
It could - don't get me wrong, it could. It could make someone see the light, see the world through a clearer vision. It could change everything. It could make people good and courteous, make them spend their lives trying to save others'. Their past could lead them to something brighter in the future, creating the theory that everything happened for a reason. It could make them grateful for their life instead of hateful, scornful, wishing they were never born.
But it wasn't like that for me; I didn't get better. For me, all pain ever did was hurt. ~ Lauren Evers

Nothing, again, could be more prosaic and impenetrable than the domestic energies of Miss Diana Duke. But Innocent had somehow blundered on the discovery that her thrifty dressmaking went with a considerable feminine care for dress--the one feminine thing that had never failed her solitary self-respect. In consequence Smith pestered her with a theory (which he really seemed to take seriously) that ladies might combine economy with magnificence if they would draw light chalk patterns on a plain dress and then dust them off again. He set up "Smith's Lightning Dressmaking Company," with two screens, a cardboard placard, and box of bright soft crayons; and Miss Diana actually threw him an abandoned black overall or working dress on which to exercise the talents of a modiste. He promptly produced for her a garment aflame with red and gold sunflowers; she held it up an instant to her shoulders, and looked like an empress. And Arthur Inglewood, some hours afterwards cleaning his bicycle (with his usual air of being inextricably hidden in it), glanced up; and his hot face grew hotter, for Diana stood laughing for one flash in the doorway, and her dark robe was rich with the green and purple of great decorative peacocks, like a secret garden in the "Arabian Nights." A pang too swift to be named pain or pleasure went through his heart like an old-world rapier. He remembered how pretty he thought her years ago, when he was ready to fall in love with anybody; but it was like remembering ~ G.K. Chesterton

No surprises" is the motto of the franchise ghetto, its Good Housekeeping seal, subliminally blazoned on every sign and logo that make up the curves and grids of light that outline the Basin. The people of America, who live in the world's most surprising and terrible country, take comfort in that motto. Follow the loglo outward, to where the growth is enfolded into the valleys and the canyons, and you find the land of the refugees. They have fled from the true America, the America of atomic bombs, scalpings, hip-hop, chaos theory, cement overshoes, snake handlers, spree killers, space walks, buffalo jumps, drive-bys, cruise missiles, Sherman's March, gridlock, motorcycle gangs, and bun-gee jumping. They have parallel-parked their bimbo boxes in identical computer-designed Burbclave street patterns and secreted themselves in symmetrical sheetrock shitholes with vinyl floors and ill-fitting woodwork and no sidewalks, vast house farms out in the loglo wilderness, a culture medium for a medium culture. The only ones left in the city are street people, feeding off debris; immigrants, thrown out like shrapnel from the destruction of the Asian powers; young bohos; and the technomedia priesthood of Mr. Lee's Greater Hong Kong. Young smart people like Da5id and Hiro, who take the risk of living in the city because they like stimulation and they know they can handle it. ~ Neal Stephenson

Finally, in 1905, he found the answer. His name was Albert Einstein, and his theory was called special relativity. He discovered that you cannot outrace a lightbeam, because the speed of light is the ultimate velocity in the universe. If you approach it, strange things happen. Your rocket becomes heavier, and time slows down inside it. If you were to somehow reach light speed, you would be infinitely heavy and time would stop. Both conditions are impossible, which means you cannot break the light barrier. Einstein became the cop on the block, setting the ultimate speed limit in the universe. This barrier has bedeviled generations of rocket scientists ever since. ~ Michio Kaku

Hell,huh? Well,hopefully we'll be able to disprove that theory soon.Besides, if it were hell,would I be here with you?"
"I don't know,if hell called for an eternity of annoyance instead of torment,maybe."
"I like you more every day.But neither of us qualifies for hell. We're victims." He smiled, the last word laced with venom. "And if we're occasionally wicked,well, certainly we'd be justified."
i wondered if he was trying to comfort me about Vivian,but he stared into the distance as though anticipating future wickedness. What did he want me to light on fire this time? I didn't think I was up for more destruction. ~ Kiersten White

For Bohr the theory came first, then the philosophical position, the interpretation constructed to make sense of what the theory says about reality. Einstein knew that it was dangerous to build a philosophical worldview on the foundation of any scientific theory. If the theory is found wanting in the light of new experimental evidence, then the philosophical position it supports collapses with it. 'it is basic for physics that one assumes a real world existing independently from any act of perception', said Einstein. 'But this we do not know'. ~ Manjit Kumar

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased. ~ Lee Smolin

Belief Systems contradict both science and ordinary "common sense." B.S. contradicts science, because it claims certitude and science can never achieve certitude: it can only say, "This model"- or theory, or interpretation of the data- "fits more of the facts known at this date than any rival model." We can never know if the model will fit the facts that might come to light in the next millennium or even in the next week. ~ Robert Anton Wilson

one of the twins went for a long trip in a spaceship at nearly the speed of light. When he returned, he would be much younger than the one who stayed on earth. This is known as the twins paradox, but it is a paradox only if one has the idea of absolute time at the back of one's mind. In the theory of relativity there is no unique absolute time, but instead each individual has his own personal measure of time that depends on where he is and how he is moving. ~ Stephen Hawking

Scientific theories never dictate human values, but they can often cast new light on ethical issues. From a sexual selection viewpoint, moral philosophy and political theory have mostly been attempts to shift male human sexual competitiveness from physical violence to the peaceful accumulation of wealth and status. The rights to life, liberty, and property are cultural inventions that function, in part, to keep males from killing and stealing from one another while they compete to attract sexual partners. ~ Geoffrey Miller

While he attends to his rats, Persinger gives me the lowdown on the haunt theory. Why would a certain type of electromagnetic field make one hear things or sense a presence? What's the mechanism? The answer hinges on the fact that exposure to electromagnetic fields lowers melatonin levels. Melatonin, he explains, is an anti-convulsive; if you have less of it in your system, your brain - in particular, your right temporal lobe - will be more prone to tiny epileptic-esque microseizures and the subtle hallucinations these seizures can cause. ~ Mary Roach

Work is style, and there is style without thought; not in theory, only in fact. When I take a sentence in my hand, raise it to the light, rub my hand across it, disjoin it, put it back together again with a comma added, raising the pitch in the front part; when I rub the grain of it, comb the fur of it, re-assemble the bones of it, I am making something that carries with it the sound of a voice, the firmness of a hand. Maybe little more. ~ Donald Hall

The full implications of feminism will evolve over time, as we organize, experiment, think, analyze, and revise our ideas and strategies in light of our experiences. No theory emerges in full detail overnight; the dominant theories of our day have expanded and changed over many decades. That it will take time should not discourage us. That we might fail to pursue our ideas - given the enormous need for them in society today - is unconscionable. ~ Charlotte Bunch

The Undivided Wholeness of All Things
Most mind-boggling of all are Bohm's fully developed ideas about wholeness. Because everything in the cosmos is made out of the seamless holographic fabric of the implicate order, he believes it is as meaningless to view the universe as composed of "parts, " as it is to view the different geysers in a fountain as separate from the water out of which they flow. An electron is not an "elementary particle. " It is just a name given to a certain aspect of the holomovement. Dividing reality up into parts and then naming those parts is always arbitrary, a product of convention, because subatomic particles, and everything else in the universe, are no more separate from one another than different patterns in an ornate carpet. This is a profound suggestion. In his general theory of relativity Einstein astounded the world when he said that space and time are not separate entities, but are smoothly linked and part of a larger whole he called the space-time continuum. Bohm takes this idea a giant step further. He says that everything in the universe is part of a continuum. Despite the apparent separateness of things at the explicate level, everything is a seamless extension of everything else, and ultimately even the implicate and explicate orders blend into each other. Take a moment to consider this. Look at your hand. Now look at the light streaming from the lamp beside you. And at the dog resting at your feet. You are not merely made of the s ~ Michael Talbot

Planck noted that although the Andromedans wouldn't have access to our rulers, scales, or clocks, they would have access to our physical laws, which are the same as theirs. They could measure, in particular, three universal constants:

c: The speed of light.

G: Newton's gravitational constant. In Newton's theory, this is a measure of the strength of gravity. To be precise, in Newton's law of gravity, the gravitational force between the bodies of masses m1, m2 separated by distance r is Gm1m2/r^2.

h: Planck's constant. ~ Frank Wilczek

The myth of quantum consciousness sits well with many whose egos have made it impossible for them to accept the insignificant place science perceives for humanity, as modern instruments probe the farthest reaches of space and time. ... quantum consciousness has about as much substance as the aether from which it is composed. Early in this century, quantum mechanics and Einstein's relativity destroyed the notion of a holistic universe that had seemed within the realm of possibility in the century just past. First, Einstein did away with the aether, shattering the doctrine that we all move about inside a universal, cosmic fluid whose excitations connect us simultaneously to one another and to the rest of the universe. Second, Einstein and other physicists proved that matter and light were composed of particles, wiping away the notion of universal continuity. Atomic theory and quantum mechanics demonstrated that everything, even space and time, exists in discrete bits – quanta. To turn this around and say that twentieth century physics initiated some new holistic view of the universe is a complete misrepresentation of what actually took place. ... The myth of quantum consciousness should take its place along with gods, unicorns, and dragons as yet another product of the fantasies of people unwilling to accept what science, reason, and their own eyes tell them about the world. ~ Victor J. Stenger

In the late 1960's, physicists Steven Weinberg, Abdus Salam, and Sheldon Glashow conquered the next unification frontier. In a phenomenal piece of scientific work they showed that the electromagnetic and weak nuclear forces are nothing but different aspects of the same force, subsequently dubbed the electroweak force. The predictions of the new theory were dramatic. The electromagnetic force is produced when electrically charged particles exchange between them bundles of energy called photons. The photon is therefore the messenger of electromagnetism. The electroweak theory predicted the existence of close siblings to the photon, which play the messenger role for the weak force. These never-before-seen particles were prefigured to be about ninety times more massive than the proton and to come in both an electrically charged (called W) and a neutral (called Z) variety. Experiments performed at the European consortium for nuclear research in Geneva (known as CERN for Conseil Europeen pour la Recherche Nucleaire) discovered the W and Z particles in 1983 and 1984 respectively. ~ Mario Livio

The generalized theory of relativity has furnished still more remarkable results. This considers not only uniform but also accelerated motion. In particular, it is based on the impossibility of distinguishing an acceleration from the gravitation or other force which produces it. Three consequences of the theory may be mentioned of which two have been confirmed while the third is still on trial: (1) It gives a correct explanation of the residual motion of forty-three seconds of arc per century of the perihelion of Mercury. (2) It predicts the deviation which a ray of light from a star should experience on passing near a large gravitating body, the sun, namely, 1".7. On Newton's corpuscular theory this should be only half as great. As a result of the measurements of the photographs of the eclipse of 1921 the number found was much nearer to the prediction of Einstein, and was inversely proportional to the distance from the center of the sun, in further confirmation of the theory. (3) The theory predicts a displacement of the solar spectral lines, and it seems that this prediction is also verified. ~ Albert Abraham Michelson

It is unnecessary to understand electromagnetic theory before wiring a lamp or to study physics in order to repair a pump. We count on our fingers and give no heed to the proliferating implications of the act. ~ James R Newman

String theory is based on the simple idea that all the four forces of the universe: gravity, the electromagnetic force and the two nuclear forces, can be viewed, as music. ~ Michio Kaku

The theory of positivity teaches us to, "always look on the bright side" and to, "point out the bright side to others". However, any highly empathic individual will know, that this mindset alienates us from other people. What connects us with other people is the ability to identify with what they are feeling and thinking, regardless of whether or not we've actually been in their place before. If you want to point someone out to the light, first you need to get into their dark cave with them, light a candle, and say, "Hey, I'm here with you and look, remember what the light feels like?" That's the kind of positivity that actually bears real change in people, in the world. ~ C. JoyBell C.

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

I have a theory," she said. I nodded at her to continue and she said, "There's this fireplace downstairs. I think I went down there for some reason. To hide, maybe. I thought it was all my fault my mother died. And I hit my head on the marble. My brain bled. I died."

She watched me.

"Right," I said. "I don't think that's possible."

"Why don't you think it's possible?" she asked. "Because everyone can see me?"

"It's not that. It's just that it seems to me that the dead only return for love or for revenge. Who did you come back for?"

Neither of us smiled. I felt light-headed I couldn't believe that we were discussing this.

"Love or revenge," she sighed. "Neither."

"Miranda," I said, "You're not dead. Okay?"

"Ore," she said. "I'm not alive. ~ Helen Oyeyemi

Is evolution a theory, a system, or a hypothesis? It is much more it is a general postulate to which all theories, all hypotheses, all systems must henceforward bow and which they must satisfy in order to be thinkable and true. Evolution is a light which illuminates all facts, a trajectory which all lines of thought must follow this is what evolution is. ~ Pierre Teilhard De Chardin

Einstein was remarkable for his powers of concentration; he could work uninterruptedly for hours and even days on the same problem. Some of the topics that interested him remained on his mind for decades. For relaxation he turned to music and to sailing, but often his work would continue during these moments as well; he usually had a notebook in his pocket so that he could jot down any idea that came to him. Once, after the theory of relativity had been put forth, he confessed to his colleague Wolfgang Pauli, "For the rest of my life I want to reflect on what light is." It is perhaps not entirely an accident that a focus on light is also the first visual act of the newborn child. ~ Howard Gardner

One day [Rabbi Spear] talked about his theory of happiness. He proposed that human feelings respond only to contrast and change, not to constancy, just as eyesight responds to contrasts of light and dark and to movement. The rabbi speculated that if emotions are similar to eyesight and other senses, then perhaps emotions were developed by nature as a survival mechanism. ~ Alan Lightman

But now at last the sacred influence
Of light appears, and rom the walls of Heav'n
Shoots far into the bosom of dim Night
A glimmering dawn; here Nature first begins
her farthest verge, and Chaos to retire
As from her outmost works a broken foe
With tumult less and with less hostile din, ~ John Milton

A billion and a half human souls, who had been given the techniques of music and the graphic arts, and the theory of technology, now had the others: philosophy and logic and love; sympathy, empathy, forbearance, unity, in the idea of their species rather than in their obedience; membership in harmony with all life everywhere.
A people with such feelings and their derived skills cannot be slaves. As the light burst upon them, there was only one concentration possible to each of them - to be free, and the accomplished feeling of being free. As each found it, he was an expert in freedom, and expert succeeded expert, transcended expert, until (in a moment) a billion and a half human souls had no greater skill than the talent of freedom. ~ Theodore Sturgeon

But historically the fourth dimension has been considered a mere curiosity by physicists. No evidence has ever been found for higher dimensions. This began to change in 1919 when physicist Theodor Kaluza wrote a highly controversial paper that hinted at the presence of higher dimensions. He started with Einstein's theory of general relativity, but placed it in five dimensions (one dimension of time and four dimensions of space; since time is the fourth space-time dimension, physicists now refer to the fourth spatial dimension as the fifth dimension). If the fifth dimension were made smaller and smaller, the equations magically split into two pieces. One piece describes Einstein's standard theory of relativity, but the other piece becomes Maxwell's theory of light!

This was a stunning revelation. Perhaps the secret of light lies in the fifth dimension! Einstein himself was shocked by this solution, which seemed to provide an elegant unification of light and gravity. (Einstein was so shaken by Kaluza's proposal that he mulled it over for two years before finally agreeing to have this paper published.) Einstein wrote to Kaluza, "The idea of achieving [a unified theory] by means of a five-dimensional cylinder world never dawned on me...At first glance, I like your idea enormously...The formal unity of your theory is startling. ~ Michio Kaku

The nature of catastrophe is, after all, reasonably unvarying in the way it ruins, destroys, wounds and devastates. But if something can be learned from the event - not least something as profound as the theory of plate tectonics - then it somehow puts the ruination into a much more positive light. ~ Simon Winchester

Another anti-theoretical stratagem is to claim that in order to launch some fundamental critique of our culture, we would need to be standing at some Archimedean point beyond it. What this fails to see is that reflecting critically on our situation is part of our situation. It is a feature of the peculiar way we belong to the world. It is not some impossible light-in-the-refrigerator attempt to scrutinize ourselves when we are not there. Curving back on ourselves is as natural to us as it is to cosmic space or a wave of the sea. It does not entail jumping out of our own skin. Without such self-monitoring we would not have survived as a species. ~ Terry Eagleton

I've been wanting to tell people my theory about what goes on after time. It's beyond our consciousness. We get glimpses of it between the infrared and the ultraviolet - the narrow narrow corridor of light that we are able to perceive. ~ Russell Brand

My theory is that everything went to hell with Prohibition, because it was a law nobody could obey. So the whole concept of the rule of law was corrupted at that moment. Then came Vietnam, and marijuana, which clearly shouldn't be illegal, but is. If you go to jail for ten years in Texas when you light up a joint, who are you? You're a lawbreaker. It's just like Prohibition was. When people accept breaking the law as normal, something happens to the whole society, you see? ~ Orson Welles
