Well, my "limb" is probably well known ...

I don't think we "know" anything, until we deal with what part the ether
plays in all this ... I see it as we are flying a plane without paying
any heed to the existence of air--I am sure it could be done--just
happen to stumble upon a set(s) of math which would allow it--it is just
a "bunch easier" knowing about the air.

How about: A photon (particle) traveling at the speed
of light causes shock waves in the aether which, when
passed through double slits, causes interference?

Impossible for empty space - but we now know that space
is not empty. :-) Quoting "Alpha and Omega", by Seife,
"Empty space is an incredibly complex substance, and
scientists are just beginning to understand its properties."

Hello Cecil,

I don't believe you can compare the two phenomena.

The photons are created because of an accelerating charge (so the
photon is the wave itself, not the source that created the wave).

However, as far as I know, there is an (almost) equivalent for the
airplane/air shockwave. When you shoot a charged particle (v close to
c0) into a material with rel. eps 1 the particle will not abruptly
slow down when entering the material with high rel.eps. So it can
have a speed that is above the propagation speed of EM waves in that
material. In that case an EM shock wave occurs. Look for Cherenkov
shockwave.

Best regards,

Wim

I should say "characteristic" impedance is 377 Ohms. It also has a
permitivity and permeability of 1 ;-)

I'm sure you mean relative permittivity and relative permeability.

No, this is not correct. The permitivities and permeabilities of all
materials are relative to free space. Free space is assumed to be 1 and
the other values are relative to it.


The characteristic impedance is the square root of permeability divided
by permittivity, so if both are one, the characteristic impedance would
have to be one.

No, this is not correct.



According to "Reference Data for Radio Engineers", published by
International Telephone and Telegraph, fourth edition, page 35:

"Properties of Free Space"

Permeability = 1.257 * 10^-6 henry per meter.
Permittivity = 8.85 * 10^-12 farad per meter.

Characteristic impedance = sqrt(Permeability/Permittivity) = 376.7 ohms

To have a mind set around liquids and solids prevent true
understanding
of the elements and their magnetic fields which is the basis of all
the universe. If one thinks of H2O as being elements with a
electrical
field where the energy contained in that field determines the density
of like particles.
One way of looking at it is the transformation from ice to a gas with
each
transformation being ruled by the change in energy ( latent energy)
One can simulate this action between a solid and a liquid by filling a
vessel with fine particles that is so dense that one cannot poke a
finger into it. When a gas (potentialenergy) is injected (now
kinetic)
into the bottom of the vessel the particles become liquid in form
such
that one can stir the contents in cluster form plus a pressure wave
in advance. Is it not a coincidence that 95% of elements are
diamagnetic
where the difference between that and paramagnetic is very small
and reflected in field strength or potential energy?

Frankly Art, until we move a bit further forward--I am very open to the
arguments/ideas/text you contribute.

My mother has always said, "It is better to listen than to think you
understand [know] it all." And, her advise has served me well in life,
so well, I have never been able to dismiss it.

JS
