I would say you are close enough to say you are correct. Because you
chose a dipole which is in a state of equilibrium and thus particles
projected from the dipole cannot collide with other particles from
other parasitic radiators. Aren't you not basically refering to the
foundations of Poyntings vector which like Gauss is refering to an
item in equilibrium when subjected to a time variable of zero value ?
If the item is not in a state of equilibrium collision
of particles may well occur without a radiation field reaction thus
one cannot calculate the resultant field since energy transfer due to
particle collision prevents the return of particles to the mother
radiator.


I've been reading Art's posts for some time now, mostly for the
entertainment value. Some of the recent posts were starting to make
sense, and this was causing me some concern: that my bafflegab
filter in the computor (sic) had gone out. Well, the above quote was
a wakeup call... I don't have a clue what he's saying. Can someone
translate, please.

Mike, you must first understand that that two unlike particles in
combination from the same radiator creates radiation. Lock that into
your mind. Other collisions or combinations do not creat radiation so
their energy has to be ascertained so they do not finish up on the
radiation side of the equation. If the radiating article is in
equilibrium there is no other radiator in competition in the same
space to create radiation thus the single radiator is free to emit
particles in isolation where errent collisions or combinations can not
occur. You must also note that all particles emitted from a single
radiator do not all finish up on the radiation side of the equation
since some return to the mother element with the same kinetic impact
that was imparted on them in the first place and thus these must be
accounted for in any equation. If one is to ascertain the final
arrangement of any energy transfer from a black box it is desirable
not to introduce energy exchange phenomina by introducing rival or
cumulative exchanges which cannot be accounted for. All equations that
do not allow for the unit of time are purely mathematical exercises of
theory thus one must be absolutely sure that the numbers add up on
both sides of the equation to justify the addition of that very
important symbol called equal. That is why the subject of ther terms
of "time" and "equilibrium" is important to transform an equation from
a fantasy form to one of reality in both Poyntings vector and the
Gaussian equation.
