Quotes About Photon

What the photon is it?" "Oh, just some five-million-year-old tape that's being broadcast at us." "A what? A recording?

Another kind of wind, raging out of the Old Sun all the while, but it slips through the hull and the photon sails like they aren't there at all. Dark-wind, some call it. Or ghost-wind or shadow-wind.

If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly.

Compton had in fact demonstrated in 1923 what Einstein had postulated in 1905 in his theory of the photoelectric effect: that light was wave but also simultaneously particle, photon.

Arnold Sommerfeld hailed the Compton effect—elastic scattering of a photon by an electron—as "probably the most important discovery which could have been made in the current state of physics" because it proved that photons exist, which hardly anyone in 1923 yet believed, and demonstrated clearly the dual nature of light as both particle and wave.

He throws the torn paper from his window into the October breeze and returns to bed. He falls asleep watching the little fragment of light vibrate across his wall, thinking how much more efficient it would be filling an hourglass with photons instead of those unruly grains of sand.

Author's Note: Barbara Hand Clow gives a much more detailed description and story about the photon band and the cosmological changes in dimensional relationships we are undergoing in her latest book, The Pleiadian Agenda: A New Cosmology for the Age of Light.]

It is important to bear in mind that this is a property of single photons. Each individual photon must be considered to feel out both routes that are open to it, but it remains one photon; it does not split into two photons in the intermediate stage, but its location undergoes the strange kind of complex-number weighted co-existence of alternatives that is characteristic of quantum theory.

For her PhD, Maria Goeppert Mayer, a theoretical physicist, came up with the idea of multi-photon physics. That means an atom absorbs two or more photons simultaneously.

The idea that light is emitted in discrete quanta of energy related to its frequency is puzzling,

So the energy per cubic centimeter is constant, while the number of cubic centimeters is increasing—the total energy goes up. In a universe dominated by radiation, in contrast, the total energy goes down, as each photon loses energy due to the cosmological redshift

My PhD project was actually doing something that required a high-intensity laser. It was supposed to work in a way that many, many photons of light would interact with an atom all at the same time.

Four thousand A.U. plus is a long trip-and that's as the crow flies. Or, actually, as the photon fires, because of course there aren't a lot of crows in near-interstellar space.

In the early days of atomic physics [before quantum field theory revealed the true meaning of the fine structure constant to be the strength of the coupling between the electron and photon], it was thought to have a value so close to being precisely 1/137 that numerologists started to establish cultish associations with the number 137.

Ama bütün çocuklar gibi kuram da kendi yoluna gitti, Einstein da onu art?k tan?yamaz oldu. 1910'lar ve 1920'ler boyunca büyümesine yön verense Danimarkal? Niels Bohr oldu. I??k enerjisi gibi atomlardaki elektronlar?n belirli bir enerjiyle yaln?zca bir atom yörüngesinden di?erine "s?çrayabilece?ini", bunu yaparken de bir foton sald???n? veya so?urdu?unu anlayan odur.

Orolo said, "What if these two universes—each as big and as old and as complicated as ours—were entirely separate, except for a single photon that managed to travel somehow between them. Would that be enough to wrench A's time and B's time into perfect lockstep for all eternity?

adding travel time lost during the pit stop between photon absorption and re-emission, the total trip lasts about a million years. If a photon had a clear path from the Sun's center to its surface, its journey would instead last all of 2.3 seconds.

The ordinary photon is a member of the boson family.

Love, that most banal of things, that most clichéd of religious motivations, had more power—Sol now knew—than did strong nuclear force or weak nuclear force or electromagnetism or gravity. Love was these other forces, Sol realized. The Void Which Binds, the subquantum impossibility that carried information from photon to photon, was nothing more or less than love.

Particle-antiparticle pairs fluctuating in the vacuum also permit the fusion of two real photons into a single one, in the presence of an external field.

The photon itself, the carrier of the electromagnetic interaction, is electrically neutral. That means all interactions among photons proceed through the mediation of other, electrically charged particles.

A single photon seems to "know" if there are two slits open or only one slit open and it behaves differently accordingly!

The photon is the first example we will encounter of a gauge boson, a fundamental, elementary particle that is responsible for communicating a particular force.

My colleagues and I recently showed that you can think of time travel, the process of going from the future into the past, as a kind of teleportation of information from now to back then. Moreover, we were actually able to use a simple quantum computer to demonstrate this effect. We could investigate what happens when you send a photon billionths of a second backwards in time.
