If you go back to the arbitary boundary of the Gaussian law of statics
and view it as a
Faraday shield it all becomes quite simple. If one adds a time varying
field you have the duplicate of Maxwells laws for radiation, *where
the outside of the boundary is the radiator.
The Faraday shield supplies the transition from a static to a dynamic
field for xmission and
the reverse action *for receiving.
Very basic my dear Watson, and a vindication that particles and not
waves create radiation
which puts it in line with deductions when other methods are applied.

Doesn't look basic, and I suspect it never will to me. The only thing I
can get from this is the idea that a particle model will do what the wave
one does, which isn't surprising but I've been told that particle based
models are usually best left to situations (usually atomic scale quantum
mechanical) where the wave model won't do, and I've never seen anyone suggest
that wave-based theories of electromagnetics were inadequate (or inefficient)
for scales involving obviously large numbers of particles. The other
explanations seemed to grip, but not this one. I'll leave well alone now, but
if anyone else takes up the discussion, I'll read it and only comment if I
can't stop myself..

Yep, that's about right. In fact, my advice if you do get into that
situation (where quantization of energy is important), is to NOT think
of particles or waves, but realize that quanta of electromagnetic
radiation behave exactly as they behave, which is neither exactly like
waves nor exactly like particles. One of Richard Feynman's physics
lectures covered what I think is a lovely example of this: how you
can NOT explain the results of the experiment he sets up, using EITHER
wave OR particle behaviour. I highly recommend it, to arm yourself
against people who get into the particle-vs-wave battle. I believe
it's the sixth of what has been published as Feynman's "Six Easy
Pieces."

That's what I kept telling myself when I first read about it 20 years ago,
that light was neither wave, nor particle, but something else that can appear
as either, or both. It felt like a kind of fence-sitting tautology at the
time, but it really seemed the only way to have any hope of resolving
(sometimes foolish) paradoxes, so it's gratifying to know that Feynman says
it too. I don't know if he's written anything a layman can easily work
through, that doesn't come with lots of maths without which accompanying text
doesn't help much, but if he has I'll try to read it.

I have various thoughts of my own, too off-topic to go into most likely, but
I'll indulge in one of them. The duality/exclusion, etc is often expressed in
various ways, but the one I find most intersting is based not in massenergy
but information, that of isolation and continuity. People have made computers
of both types now, basically the Turing machine and the operational
amplifier. I suspect we have a third type, the brain, that isn't 'modelled'
on either type but uses the quanta as they actually are. Though whether
attempts to make actual quantum computers will be anything like what the
brain does, I have no idea. But it seems to imply that there might be a
'conservation of information' law as there are such laws for mass and energy
or mass-energy. Maybe information is more fundamental than either. If so,
some very strange science is going to emerge (and I suspect it won't be
quantum theory that gets us anywhere, as such, especially given the
Copenhagen Interpretaion and what that implies about 'knowing', but the tools
it enables us to build are another matter, I think they're going to show
plenty, once we have enough new info to interpret).

As continuity as well as isolation is a fundamental aspect of whatever is
'underneath', it means I have no reason to reject a wave model of
electrodynamics if it works, so I won't.

I think one of the key things that made his physics lectures popular
is that they were delivered without a whole lot of math. You could
get into that if you wanted, but you could also get a lot out of just
listening to the _ideas_.

If you drop me an email, perhaps I can send you a bit more about this
particular lecture...

That is oh so true! The masters started with an observation of an
occurence and not from
a rendering of mathematics. With more observations it became natural
to align the Universe via mathematics which, as with a jig saw puzzle,
fits together nicely.,
It would seem today that scientists today are using mathematics via a
computer to churn out bundles of equations leaving the operator to
think of an observation that would fit the math. Of course,
mathematics provide imaginary answers similar to a quadratic equation
that finish up as multiple of false leads and deductions which
eventually requires the multiple use of constants to provide a
semblance of understanding of what has been provided.

Thankyou, I'll go for that. I've also been given two books by Marcus Chown,
who I found has a knack of conveying things clearly at some depth.
Entertaining too. My email is (slightly obfuscated) z dot crow at BTinternet
dot com for as long as I still use their service. (Contract runs out fairly
soon so even though they're ok I'm looking at alternatives..
