quantaised nature of photon?

[Mr. Nobody]

They way I understand it is that a photon is a unit, a quantity of something measurable (energy or matter). Photons don't exist, they are not flying nuggets of light, they only represent information of the underlying wave and are used to explain interactions. You don't see a milimeter flying around either. But you can apply that milimeter to measure something.

Let's play imagine this for a moment, and let's pretend that out in space the ones and the zeroes flying around can seem alike, like arcs that are formed out of the spaces they displaced are the same and form little arcs above the one and the next one and the next one and the next one, The formation of the little arc shape is a natural one being the early reaction of bacterial formation that precluded RBC production by millions of years, but set the stage for the geometrical plans to be realized in full size as projected by the quarks to the size of the electron to be. The quarks photomultiplied the size of the electron exactly to the orbit exactly, with no uncertainty. The RNA in 3 types similar to stem cells in 3 types, would work together in matrix form to make the pattern available in a form that would be pleasant to your eyes that would form in your head.

4.5 million year old bacteria get respect. Today, in the lab, it gets cleaned up like garbage. Do we have an open line of communication here? The bacteria that possibly is responsible for Mars Science Behavior(Not Life) Per Se may lead you to where you would like to go if it thought you would not drag it through the proverbial mud. It may be conscious even after 4.5 million years and capable of teaching a class or two in Astrophysics at it's age.

No magic Michele. Consider the anthropic principle to its fullest extent. We are here observing and wondering about the perculiar ratios of this and that because we can not objectively assess how often things went the other way. Granted any other way, would produce a universe that might look very different and might have been short lived or dead on arrival, but who is to say that that has not happened already somewhere, sometime, trimming the possibilities to this very one local reality we exist in today. Look at us humans, and how long it took to get here and again, who is to say we are meant to be the end product, the ultimate....only we feel that way, the dinosaurs most certainly would disagree
All I am saying is that every age, every epoch of the universe will feel unique and special to its observers, and even if only the current time produced observers then the act of knowing does not make us more or less unique either. Taken as a whole, the cosmos has no plans for anything other than perpetual energy exchange (matter alignment) and we are what happened to happen along the way, nothing more nothing less

Hey i just understand what David had mentioned "there is no such thing as a photon". because it has no real mass and it is just a form of energy. We tend to think that the smallest form of energy E = hv can be consider as one photon, but its not true, because that is just the indication of the energy required to generate the smallest amount of "photon". we can use a magnifying glass to increase the intensity of electromagnetic radiation (light). but no photons will have collision with each other.

but one question, i wonder what would happen if we try to split the smallest photon form E = hv by some device. My opinion is that it is not possible. but i don really sure about it.

Photon has a really unique property. It has an absolute time if that is the right way to describe. because it travells about 3.00x10^8 m/s no matter what your inertia frame of reference is. That is probably why we use it to describe our length measurement. and our world revolve around it. In a sense like our length and time just inversely proportional and yet the "c" remains constant.

Kismet;
Maybe this will help to visualize the unit of energy called a photons. The equation, “E=hv”, is the old style when “v” represented frequency; the more common one today is “E=hf” but the main thing to note here is that it is frequency and thus a rate of energy absorption or emission. The photon can be viewed as the portion of a wave front that interacts with an electron. The quantum unit that represents the photon is Planck’s constant “h” and its relative mass can be calculated using E=mc^2 and substituting “E” with “h”, for m=h/c^2. Now you can say how many wave fronts per second it takes to cause the photo electric effect of one electron.
