Hi Mr. Green, studied your post

More than it merits, I'm sure.

You've used the term "configurational entropy" twice,

Configurational entropy refers to an entropy term calculated based on
the configuration (distribution in space) of the bits of matter.

Suppose it does classically, the focus of the problem
is the question as to how repeling (LIKE) charges
radiate, and if they do, by what mechanism, then
we need to determine how they absorb photons.

We may at least ask the question purely classically, without a photon
in sight: I give the charge and the field an initial condition, I let
it go, and the system evolves according to the laws of electrodynamics.
I then ask of this solution "is there radiation"? Ambiguities, other
than our ignorance of the actual solution, stem from:

(1) meaning of a charge -- point or finite

(2) meaning of radiation

Perhaps

(1a) nature of mass (electromagnetic or inserted by hand)

<...>

Kindly put. I may repost this question in a fresh thread, on the
theory that most posters will loose interest in a lengthy dialogue, but
will at least give a new topic a once over. Maybe somebody can point
out the fly in my logic.

My sense is we should take care of thinking
classically or in terms of QM. We are naturally
prejudiced to the continuum by our indoctrination
into the newtonian differentials, however as I
pointed out above, Purcell's dW really becomes
Delta W in QM at the particle level.

For what it's worth, having put the question to experts, I'd say the
expanding spherical shell of charge does not radiate, a conclusion
backed with crushing force of logic, and that the expanding pair of
charges probably does radiate, a probability so far backed with
somewhat less than crushing force of logic, but some evidence
admissible in a civil trial. I reserve judgement.
