Re: Planck's Constant: What are light quanta?
- Modern accelerators are used as advanced light sources. Once the
electromagnetic wave leaves the vacuum and interacts with matter, it
may be absorbed and then emitted at the same energy or at a lower
energy via a combination of radiative and nonradiative processes.
Planck thought his constant was a property of matter based on an
idealized blackbody radiator; Einstein thought in 1905 discrete quanta
were a property of light. Later Einstein bemoaned not understanding
photons further and searched for a unified field theory. Bohr's model
described hydrogen and quantum mechanics was unable to find the proper
potential energies to explain atoms beyond helium. Incidentally, the
Copenhagen interpretation may have been a "red herring" which led
German scientist Heisenberg to his uncertainty principle while Bohr
escaped occupied Denmark to warn the US of the Curies 1930's Nobel
Prize and later work by Hahn/Meitner.
Based on different boundary conditions and classical wave mechanics,
Randall Mills has described atoms through n=20 and many molecules. For
all these atoms and molecules, Planck's constant is a fixed absolute
scale factor which converts the frequency of the incoming wave into an
atomic or molecular energy. This understanding of Planck's scale
factor constant extends beyond our understanding of a blackbody
radiator and hydrogen to perhaps in the near future to the entire
periodic table. I don't know why any energy scale factor should
inherently remain the same for different atoms and molecules but it
Advanced light sources are also called advanced "photon" sources.
Apparently these advanced light sources can create many frequencies or
wavelengths at high intensity for which there is no absorption by
matter. I am just suggesting that photons correspond to energies for
which atomic and molecular matter absorbs discretely rather than
continuously like an idealized blackbody radiator. "Photon" light
sources are only useful when we know the set of frequencies for which
to tune the incoming electromagetic wave.

I think you're right on track with that idea. In fact, Sir James
Jeans about a hundred years ago found that the wavelength of a photon
that is either emitted or absorbed by an atom is a constant - that
being several hundred times the diameter of the then conceived "orbit"
of the electron.
So it seems as if this is really a geometry problem. In other words,
how does the movement of energies comprising a photon translate into
the movement of energies comprising an electron orbit or "orbitsphere"
at the time of emission or absorption. The process seems to be
symmetric so that's a strong clue.
Surely the correct model of such a process involves the Haus condition
for radiation or it's converse. Or at least the principal of why
something like the Haus condition should arise, don't you think?
- bobb_bell, it's been nearly two years since you urged the moderator to reject my post for "mentioning religion," but it still bugs me and I'm compelled to get this off my chest.
In fact, while your reply to me (message 446) mentioned religion, my reply to markviverson (message 445) did not. I simply stated my skepticsm that the first living organism on Earth could have spontaneously assembled itself. For all I know, it could have been assembled by a very clever robot named Clarabell.
I want to thank moderator John Farrell for his tolerance during that incident.
Moderator's note: I do remember the incident but not the details (getting old). Although I consider myself an atheist I must agree with DP. After the theory of evolution , the synthesis of urea, and the production of amino acids in the Miller experiment (zap a mixture of ammonia, methane, water and so on; University of Chicago early 1950s) many thought the case was closed against the theists. However, in the same year that Miller published the results of his experiments Watson and Crick published their DNA structure. Almost overnight the attention turned from amino acids and proteins to DNA as the central aspect of life. The Miller experiment was repeated, many times, and no DNA bases were found. Since then many scientists have changed their mind as to which gases the early atmosphere contained and repeated the experiment--still no luck. I know that biologists and chemists have found that lipids do form "bubbles" and can contain chemicals. I know that a lot of research is going into how certain chemicals are formed and how they can organize themselves. I also know that even the simplest organism is extraordinary hard to make from scratch (to put it mildly!). At any rate, I take a wait and see attitude in these matters. After all, reality is stranger than fiction and we still have not determined from whence (and how) we came. As moderator, I consider the relevance of a post to SCP and even then there are limits (for example, some threads run out of steam and have to be ended). If bobb_bell and DP wish to continue this thread they will have to do it without SCP as an intermediary. Best regards to both bobb_bell and DP. I hope DP's chest feels better. John Farrell
