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.

Odd question but I will respond to prevent bad thoughts.
For this group this discusion has lasted several years and only two
agree that the theory is worth reviewing. On qrz there have been two
threads which has in the order of 8000 + views including a posting by
Tom W8 TI which pleased me as he always follows up with a full
analysis that destroys various claimes put forward. This time he has
failed to place his resonings in writing so basically he is agreeing
with other hams that it is a fraud. Nobody on QRZ expressed any
confidence in my theory and again nobody provided anything to back up
the opinion of fraud. If one went by poll within the amateur group
there would be rousing agreement that it all is a fraud both in
thought and action. If one was judged in terms of debate then it is
two to zero as they were the only ones to express "why" it was worth
consideration. So If hams are the experts they think they are they do
not have to prove their competance and just go by the polls.
As an aside Jeffries who is the antenna adviser for a U.S.magazine
stated that static had no part in ac or dc circuits. I believe he is a
professor or teacher at a university in Sussex U.K. having held
similar positions in the U.S.
I believe that the above answers are the truth as I see it and what
you asked for.
Kotar has been the most critical and I leave it for you to review the
archives for his postings explaining his position which appears to be
par for the course on this newsgroup.

Interesting video on the double slit experiment which reverses "waves"
back to "particles".
I wonder how long before the books are changed back to the thoughts of
Newton and possibly my proof with respect to particles? Its a shame
that the professors on the physics
forum are still in a pattern against change or just not up to date in
the absence of a new up to date book. Of course it will take much
longer for the ham community to reconcile themselves and it may take a
new generation to adjust.
And a bit longer for QST and Radcom as they have a back log of
articles with respect to soldering connections on coax, morse code key
design and push pull tubes used in radios!
I am extremely happy regarding the helical spin shown which I
determined as a scalar reaction to the rotation of the Earth as it
gives more credability to my position that it is one of the two forces
that make up the Standard Model.( see unwin antenna page) as well as
the notion of tipped verticles to reflect same

Mike you know and I know that the double split experiment was
interpreted as evidence
that radiation is created by a wave and not a particle as in quantum
mechanics. This being in opposition to the thinking of the masters of
the day . The descision made went far beyond the duallity stage when
they made this interporetation. Now it is called the infamaos
experiment as they have now identified the initial observations as a
result of particles. To my knoweledge there is no books available for
University students to get up to date as physicist are reluctant to
change or to admit errors. Until this is done students will
continue to remember what the books state to pass their examinations.
A long time has passed since the time of Maxwell and the books still
force Universities to stick with fields and waves where nobody can
procede in the search for truth as we do not know the mass
of the waves or the energy mechanism of the revolving door of such.
This group who have been taught to memorize what a professor states
and not to question by first principles of what is stated then they
all know what to encircle at exam time from a to c which is what the
professor said and has nothing to do with reality. It is not
surprising that Einstein failed in his quest to describe the Standard
Model as he was building on the shoulders of those that preceded him
on the assumption that they were free from error. Now with computers
we have a tremedous amount of formulas that are built on errors which
leaves huge gaps in understanding and the number of constants and
predicted particles to make sense of all these manufactured formulae
based on error. It is not surprizing that physicists are getting away
with all this tripe by stating that all those outside the discipline
are all crackpots as they have had no instruction on their version of
the discipline of mathematics. Now we are all paying for the multi

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)


http://www.amazon.com/Electromagneti...ion-George-Bek...


http://mitpress.mit.edu/catalog/item...d=7576&ttype=2


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.

Mike you know and I know that the double split experiment was
interpreted as evidence
that radiation is created by a wave and not a particle as in quantum
mechanics. This being in opposition to the thinking of the masters of
the day . The descision made went far beyond the duallity stage when
they made this interporetation. Now it is called the infamaos
experiment as they have now identified the initial observations as a
result of particles. To my knoweledge there is no books available for
University students to get up to date as physicist are reluctant to
change or to admit errors. Until this is done students will
continue to remember what the books state to pass their examinations.
A long time has passed since the time of Maxwell and the books still
force Universities to stick with fields and waves where nobody can
procede in the search for truth as we do not know the mass
of the waves or the energy mechanism of the revolving door of such.
This group who have been taught to memorize what a professor states
and not to question by first principles of what is stated then they
all know what to encircle at exam time from a to c which is what the
professor said and has nothing to do with reality. It is not
surprising that Einstein failed in his quest to describe the Standard
Model as he was building on the shoulders of those that preceded him
on the assumption that they were free from error. Now with computers
we have a tremedous amount of formulas that are built on errors which
leaves huge gaps in understanding and the number of constants and
predicted particles to make sense of all these manufactured formulae
based on error. It is not surprizing that physicists are getting away
with all this tripe by stating that all those outside the discipline
are all crackpots as they have had no instruction on their version of
the discipline of mathematics. Now we are all paying for the multi
million CERN project that is intended to break the smallest particle
known to obtain a lesser mass so the speed of light can be exceeded.As
for the Higgs field
predicted by their wierd forms of mathematics it will be found as a
constant squared divided by the mas of numourous unfound but predicted
particles!

Hi Art,

The problem with many of these discussions is that there is a mathematical,
perfect model and then the real world. The real world is imperfect and full
of minute flaws and discrepances that tend to be smoothed over and cancelled
out at large scales, but have very real effects at molecular and smaller
dimensions. The mathematical models will work just fine at making
predictions in the every day world we are used to, but tend to fail when
scaled up to the truely immense or down to molecular levels. This is not
necessarily a fault of the maths or the theory, it just means that not all
the factors that affect the calculation are known or accounted for.

People have indulged themselves in calculating PI to umpteen decimal places.
What is the point? By the time you get to 100 decimal places you could
probably plot a single atom anywhere in the known universe to within a
fraction of its diameter. A third displayed as a decimal fraction comes out
as 0.333... but we also know that the 0.00...1 does not actually exist. So
there is a flaw in the way that a fraction can be displayed at a very basic
level in mathematics and this does cause errors in calculations. These can
be accounted for by using different methods to arrive at the correct answer,
but the calculation is a lot more complicated using decimal arithmetic than
just adding 1/3+1/3+1/3 and arriving at the correct answer of 1.

So the answers you get seem to depend on the methods you use. The skill is
in deciding what is the most appropriate method that gives a best match to
the observed results and also gives the most accurate predictions for the
results that might be observed in future experiments.

Science creeps along step by step improving accuracy and developing models
that more nearly match the real world with each generation building on the
foundations of those that have gone before.

Maxwell's equations have served pretty well and I'm personally not convinced
that adding a time term to the equations is necessary to improve everyday
predictions of antenna performance. You, of course, disagree because your
antenna designs are supposed to generate RF in a different manner to
conventional designs. I don't have a problem with that at all, you have to
use the most appropriate tools you have to support your ideas. But novel
ideas are always a hard sell and it is always an up hill struggle to
overturn an established orthodoxy, no matter if you are right. Unfortunately
it takes time for new ideas to become accepted. Most of the Nobel prize
winners seem to have waited many years before their achievements are
acknowledged. It seems a shame that they win a prize at the end of their
careers when one wonders what they could have achieved with the additional
funds if they had been available at the peak of their abilities. Such is
life.

Incidently, I'm a great fan of CERN and the fusion projects. I know they are
currently seen as huge white elephants and an unnecessary drain on the
economy, but I believe that they are necessary for future science and
securing a viable means of sustainable power generation. Finding a Higgs
particle may not have a direct effect on your everyday life, but it does
have enormous implications for the future of physics and pedictions about
what may or may not be possible in the future.

Mike g0uli

Look for yourself.

You are such a martyr. My guess is that you were banned from a
moderated forum because you made a nuisance of yourself. But your will
always be able to come to r.r.a.a. and be as absurd as you care to be.
