It was an experiment in skin depth.

Strictly speaking the page describes a demonstration from page 321 of
this book:

G. Bekefi and A. H. Barrett, Electromagnetic Vibrations, Waves and
Radiation, (MIT Press, 1977)

A reviewer comments, "MITonline offers the course based on this book
for free. The course is great! This book is a less engaging, but a
more comprehensive version of A.P. French's original text for the
course. There are many gems in the book, such as insights into
microwave oven fundamentals, that are not present in basic texts.
Beware the softcover binding, it needs a gentle hand. "

What does the book point to, waves or particles? We all have plenty of
books and all cannot agree on the subject on radiation! In other words
they have placed their own interpretations of the observations seen
with the double slit experiment as over ruling of all and cast in
stone. This is what the physics forum sponsered by Scientific American
said to me as they banned me because of my temerety in challenging
their position.In addition they stated that it is not possible outside
the physcics spectrum to challenge anything which thus puts all in the
spectrum of crackpots. Dr Davis of MIT provided the mathematics
that confirmed the presense of particles, but mathematics was not
considered a reputable answer compared to the majority argument that
the mathematical aproach was illegal.
So waves hold the majority in the books but by its very presence all
understanding of radiation has been *stymied for the last hundred
years by the resistance to change without any accumpanying facts and
where physicists refuse to review to re examine what they state is now
"cast in stone." New books are written every year via plagarisation
for personal profit where the professor orders purchase of such books
for his pay off. Not one has come out with a review of radiation and
why progress has been stymied. And that goes for Radcom and QST who
have no real interest in advancing the hobby of its members.

Art,

The double slit experiment clearly points to particles or photons. The slits
are very narrow (otherwise the experiments don't work) and the wave like
properties are caused by the interaction of the particles with the atoms in
the walls of the slit as they pass through. The slit is modulating the
particles if you like.

We know that individual particles are involved because they can be counted
one by one through a detector.
We know that wave like properties are involved because of the effects
observed on a screen placed behind a diffraction grid.

The observed properties are due to influence exerted on the particles as
they pass through the diffraction grid by the atomic structure of the grid
itself. Unless the experiment were carried out at absolute zero, the atoms
in the walls of the slit are vibrating and must influence the photon as it
passes through.

At absolute zero, nothing would be moving, including the photon, so the
experiment collapses at this point.

Photons are particles that display wave like behaviour under particular
conditions.

I totally agree. Many things have attributes that other things have
but humans say that if it has a tail like a dog then it is a dog!
History shows that the interpretations ascertained from this
experiment was expanded to provide *data to conclusavly say that
radiation" is" a accellerated wave and that is carved in stone i.e.
conclusive by physicists who made that descision without over sight
from another discipline.Cast in stone is a finality for physicists
who time after time dtate that their manipulation of mathematics prove
the existence of another particle that is predictable but we have just
not found it!
Now the shoe is on another foot, I have to provide an alternative PLUS
prove it where others don't have to.
To respond I used *EXISTING LAWS and the mathematics that represent
them. Gauss stated his law as a measure of "an instant" in time
recognising that flux is mobile where at any "instant" of time the
boundary was in equilibrium. So I added a length of time where a time
varying *field was added. All this being in cgs units. When the units
were changed to be the same as Maxwells equations (MKS) they showed
that they were one and the same which cemented the position of
particles as being present in the makings of radiation.
I am using common mathematics with established accepted laws and
nothing more but I am being asked to prove its legality which is
beyond reason.This establishes some consistency in the use of both
classical and other strains of physics that when applied to the same
problem also provides the same answer. What more can be said? Articles
now declare that interpretations made years ago are not as we thought,
but it is to late now for change as decisions in physics are the
result of polls and not reality.

As I run through some other physics books I see situations that abound
where a static field is made dynamic! It just doesn't make sense that
hams who consider themselves as experts with respect to antennas can
now suddenly declare that it is now deemed illegal
I suppose with respect to free speech one can say anything if they do
not care about their credability of being an expert.This is not just a
single ham but the majority of the hams
commenting on this group. If a poll is taken then hams have proved
them selves to be in the right and truly expert.
