A Quote by Richard P. Feynman
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.

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.
It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].
Thus we can get the correct answer for the probability of partial reflection by imagining (falsely) that all reflection comes from only the front and back surfaces. In this intuitively easy analysis, the 'front surface' and 'back surface' arrows are mathematical constructions that give us the right answer, whereas .... a more accurate representation of what is really going on: partial reflection is the scattering of light by electrons inside the glass.
I therefore take the liberty of proposing for this hypothetical new atom, which is not light but plays an essential part in every process of radiation, the name photon.
The question of how the eye works - that is, what happens when a photon of light first impinges on the retina - simply could not be answered at that time.
Light is something like raindrops each little lump of light is called a photon and if the light is all one color, all the "raindrops" are the same.
What we see is the solution to a computational problem, our brains compute the most likely causes from the photon absorptions within our eyes.
Photons come out of nowhere, they cannot be stored, they can barely be pinned down in time, and they have no home in space whatsoever. That is, light occupies no volume and has no mass. The similarity between a thought and a photon is very deep. Both are born in a region beyond space and time where nature controls all processes in that void which is full of creative intelligence.
If a little kid ever asks you just why the sky is blue, you look him or her right in the eye and say, 'It's because of quantum effects involving Rayleigh scattering combined with a lack of violet photon receptors in our retinae.'
When enough electrons within an atom get aligned and a critical mass is reached - as soon as you hit that hundredth monkey, as soon as you hit the one - you have phase transition, and all the rest of the electrons automatically make the change. My mission - what I teach and what I believe in - is that you just get yourself aligned with God-consciousness. If we teach enough people to do it - if enough of us ultimately get there - then we'll start electing leaders with this kind of consciousness. We'll start seeing kinds of shifts taking their place.
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 Heart of Gold fled on silently through the night of space, now on conventional photon drive. Its crew of four were ill as ease knowing that they had been brought together not of their own volition or by simple coincidence, but by some curious perversion of physics- as if relationships between people were susceptible to the same laws that governed the relationships between atoms and molecules
So if we're all quarks and electrons ..." he begins. What?" We could make love and it would be nothing more than quarks and electrons rubbing together." Better than that," I say. "Nothing really 'rubs together' in the microscopic world. Matter never really touches other matter, so we could make love without any of our atoms touching at all. Remember that electrons sit on the outside of atoms, repelling other electrons. So we could make love and actually repel each other at the same time.
The medieval doctors of divinity who did not pretend to settle how many angels could dance on the point of a needle cut a very poor figure as far as romantic credulity is concerned beside the modern physicists who have settled to the billionth of a millimetre every movement and position in the dance of the electrons. Not for worlds would I question the precise accuracy of these calculations or the existence of electrons (whatever they may be). The fate of Joan is a warning to me against such heresy.
What the ultrafast laser does is that because it doesn't have to just cut from the surface, it's only at the intense focal point that it does this damage where the electrons come off the atoms, you could actually put your laser and scan it over your cornea and it would cut underneath that.
When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.
