To Scientist Eng Jaques Lavau ,

thank you for your comments i just have an important issue to add:

"i recommend you as a Quantum mechanical experts to revist and revisit the light quantization as a form of non- photon ,, i mean light quantization in the form of a standard photon is too far from reality because :: i suggest :::

not all photons are similar "

photon can never be a unit of light such as a kg for mass or meter for length nor sec for time , photons are neither similar in spatial nor in temporal shape .

a big problem on the quantum mechanical understanding will be solved if this issue is corrected

i will do my best to re arrange my emails

I apologize, for not knowing

Dear Dr.Eng.Preston Guynn ,

Your explanation are fabulous . many thanks for your great interest , i am just reading your answer now I found it right now . It will take me 2 days to read your 2 attached papers of Electrostatic force and thomas precession ,

I was just reading the Einstein's paper explaining the theory of stimulated emission from the following link::

https://einsteinpapers.press.princeton.edu/vol6-trans/238

I am stuck from equation 10 to equation 20 as if Einstein had some discontinuity on this part , the insersion of brownian motion in the stimulated emission needs more explanation , do you have any suggestion or idea to understand this part from equation 10 to 20 , many thanks indeed

Preston Guynn ,

Dear Dr.Eng.Preston Guynn ,

i confess that your papers you sent to me are exactly what i have been searching since a long time , but your papers electrostatic force is still difficult for me ,

my brain is badly step by step, but certainly your paper is step by step ,

i always try to understand everything like why 1+1= 2 ,,

so can i ask you please to recommend to me the document to read to be able to understand your great logic papers ? for example which book chapter or document or paper to read to understand your paper of electrostatic force , after reading your paper i will be too honored if we make an audio conference using zoom or skype , this will be step number 2 if you have time and accept it , but first could i have any pre paper or book chapter , many thanks

Preston Guynn

Dear Dr.Preston Guynn,

My appreciation to you for your valuable answer to my question , while reading your logic and marvelous explanation i said to myself ; if i were you i add these explanation to my paper and republish it , i expect the impact factor of your paper after feeding it with your explanation will boom , because this area all over the world is lacking explanation , as you know better that the whole world now is a very logic one, so this subject is too dark to most of scientific and specialized people as well .People who are in that domain suffer a severe lack of understanding internationally, think about it . Feeding 5 equations between each 2 equations in your papers and adding your comments will become tremendously fruitful. Moreover it will allow scientists, researchers to know its weight.

scientists are too shy now to say i know such equations as is or by heart , they live with it , waiting for explanation . This is my modest opinion . I return now back to your answer to start the 5th paragraph . will come back to you in few hours after reading your answer reflecting it to your paper then commenting

Dear Dr.Preston Guynn,

i suppose my knowledge in mathematics can allow me understanding your paper ,

my knowledge in mathematics it is o.k , calculus o.d.e , p.d.e., ,, mathematical induction , binominal theorem with all its exponents, permutations combinations ,analytic geometry 2d -3d , hyperbola, parabola ellipse , and its generated shapes hyperbolic paraboloids etc , descriptive geometry ,

fourier series, fourier transform, laplace transform, z transform, special functions alpha beta , bessel , , numerical modeling with moment methods , matrices , determinants , eigen value , matrices functions

modeling using time domain.model , frequency domain model , now working on mixed time frequency domain (wigner transform) ,

most important is the transition from one equation to another on your paper, certainly this is not only in your paper it is common on many advanced papers this is a major problem international problem .

Dear Dr.Preston Guynn,

I am progressing on eistein's paper and peacefully reached equation 14 below,,

https://einsteinpapers.press.princeton.edu/vol6-trans/239

soon i will come back to your great papers that i recommended , great work is yours and will be greater if you feed it with more explanations and equations between your originally ones .

a photon is going to be absorbed by an electron located inside an atom to go from a lower energy level to a higher energy level

a similar photon is going to be absorbed by a molecule of atoms oscillating at a certain oscillation mode to make (the atoms inside the molecule) a transition to a higher oscillating mode .

both similar photons in the 2 cases they are same photons but the first absorbed by an electron and the similar second photon one is absorbed by a full molecule

in both cases the emitter is the same but the absorber of the photon is totally different , one is the electron that directly absorbs the photon and raises its potential energy or p.e+k.e and in the second case , the molecule absorbs the energy and transfers it to the atoms ,,

what is the receiver of the energy inside the molecule in the second case ???

how the molecule transfers this energy to the atoms ?

what is the transient behavior till reaching the full higher oscillating new mode of oscillation?

Dear Dr.Preston Guynn,

I was reading Einstein Paper on quantum radiation and was blocked by equation 14 below (from where was it deduced any idea please or even hint) many thanks

the link is below

https://einsteinpapers.press.princeton.edu/vol6-trans/239

The only way I imagine a photon is a finite wave train, with more or less well defined frequency, of about a meter or so long. If you do a certain amount of work in a lab, in optics or spectroscopy, you eventually arrive at something close to this.

You cannot just use any old distance to see interference effects for radiation from a common source, you are limited by the extent of the wave train. It can be longer in the case of lasers, if they are good lasers. You loose the coherence of the light beyond such distance.

Preston Guynn ,

Dear Dr.Preston Guynn,

I am too thankful for your help and documents you sent but if you could send a link please or any document or paper that is from beginning to its end it will be more helpful to me difficult to me to start from a part of a paper or book , any link that explains what you said will be too appreciated

Preston Guynn

Dear Dr.Preston Guynn , Many thanks , i was searching for a smaller paper for example or a pdf arixv for example i will try myself , if you got thanks for forwarding it

Juan Weisz

Dear Dr.Juan Weisz ,

I read and reread your answer , you quoted :

"The only way I imagine a photon is a finite wave train, with more or less well defined frequency, of about a meter or so long."

you also quoted :

" It can be longer in the case of lasers, if they are good lasers. You loose the coherence of the light beyond such distance"

I could not get your point please expand your explanation in a simpler way , many thanks

Magdy

To get interference the photon, as a wave, should interfere with itself. It cannot do so beyond the distance defined by its length. This is called coherence length.

Juan Weisz

i certainly understand temporal and spatial coherence and teach them , but the link between your answer and my question is difficult to understand , any paper or extra document to explain your words ? thanks

I thought you are asking how long a photon is and how long it lasts.

If I say it is for example 2 mt long, it would be absorbed at the speed of light, you work out the time using the speed of light. Basically the time for an atomic transition. For emission also.

If you measure it, use coherence length.

You can look through Quantum Optics, but they dont give you very simple answers.

If you can measure line width, you use the uncertainty principle. It should give you about the same time.

Juan Weisz ,

please comment on the following thought regarding heisenberg uncertainity:

in a maser for example delta E (between 2 energy levels ) is too close so

the uncertainity in energy according to heisenberg is the difference between the 2 energy levels we can treat it as if as if the electron is uncertain on existing in any of these 2 levels , as the electron can exist on any of these 2 levels so we can consider it as this delta E to be the uncertainity in an atomic system where the transition will take place so:

delta E X delta T= delta E X (T2-T1) or =h plank

from which delta E (difference between 2 energy levels)= hX2XpiXf=hX omega

which is N.Bohr postulate derived from E.Heisenberg

I would perhaps leave as delta T, uncertainty or error in a single timeT, for transition time between the two levels. If the time is very short, you just use the time itself.

For a level transition deltaE = hbar omega = hf

hbar= h/(2 pi).

Thus the uncertainty in delta E, is also the uncertainty of hf, there is a finite line width in frequency of the radiation.

In general delta E is uncertainty in energy, not level difference in energies. For this special case they are the same, since levels are very close.

If delta E is uncertainty, delta E delta T =h

Use two different deltas, for two different meanings.

The more proper law is greater or equal to h/2, but people write it this way as an estimation.
