Dear Martin,

It is great communicating with someone who has also thought about the
issue. My comments are sometimes too cryptic because I assume that you
would have come to the same conclusions. Let me try (in brown) to identify
some of the differences below.

 The levels identified with the classical description agree with those of
the mechanical (QM) system.

[Exactly, therefore it cannot radiate a photon except to a system w ang.
mom. = hbar. No levels below gnd state have that value.]

There is no reason *given* that the wavelength cannot fit 2 cycles rather
than one. Is it more difficult than having n wavelengths in a single cycle?
(ref Lissajou figures) This is the basis of Mill's hydrino states. The
limiting factor is the photon.

The solution assuming an infinite mass nucleus (hence no deBroglie
wavelength & no resonance) still produces discrete levels. Therefore that
issue cannot be causal.

And, it will be considered valid until experimental evidence show
otherwise. Then, 60 years of mathematical 'proofs' will immediately
disappear. Do you know of any nuclear physicist who would consider the
nuclear Coulomb potential to be a singularity? Even before the quark model
became popular? What is reality, a singular potential that contains all of
the energy in the universe, or a presently measured finite charge density
of the proton and neutron? Feynman jested that the whole universe consisted
of a single electron oscillating back and forth in time. If it was singular
and contained all of the energy in the universe, maybe Feynman's jest was
correct.

Do you consider the proton charge radius to be its field-energy density or
the major extent of its *Coulomb potential* (e.g., the electron Compton
radius)? We haven't defined charge yet have we? [Am I being the
mathematician now for insisting on a valid definition?]

In some frame of reference, the relativistic mass is infinite. However, the
charge field changes in that frame also. In the rest frame, PE is finite
and 1/r must be limited.

 This, like relativity, makes a big difference in some fields of physics.

I think of the surface of a ball of yarn! Only photons can pass thru each
other (or itself), thus the electron is more than a fluid. It is
circulating in *all* directions. Uniquely, it can have an infinity of
angular momenta. That is why it can have spin 1/2 in *any* direction you
wish to chose. That question puzzled since college days; but, I was too
'young' to properly question the 'cant' being fed us. I don't think that
the professors, bright as they were, could have understood my question,
much less answered it. (What about a spin axis along the time direction?)

Introducing the reduced mass (and a nuclear deBroglie wavelength for
'resonance') changes the values, but not the nature, of the discrete energy
levels. The nucleus travels~2000 orbits before it completes a single
deBroglie wavelength. How come the electron is only allowed a maximum of a
single cycle?

Are you assuming that the electron is a wave and not localized? That its
wave function, distributed around the atom and extended to 2 orbits per
cycle, would cancel because of phase reversal? Then what about 3 (or any
odd integer) orbits?

had thought of relativity as applied to the deBroglie wavelength rather
than being fundamental to it. I'm finding that my youthful disinterest in
the history of physics is extracting a penalty now.

I don't have his Thesis handy; but, in his "Theory of Quanta," he does
provide support for your earlier statement about resonance between the
nucleus and electron.

"This is exactly BOHR's formula that he deduced from the theorem mentioned
above
and which again can be regarded as a phase wave resonance condition for an
electron in
orbit about a proton."

If this is also considered resonance, rather than just strict mechanics,
then the energy levels have 3 resonances in coincidence.
