Of course, technical authors avoid absolute assertions because they know that almost all knowledge is proven inaccurate sooner or later by the additional acquisition of human knowledge driven by finer-tuned experiments. What you don't seem to understand is that technical knowledge builds upon technical knowledge so that the latest theories that support the latest experiments are the best "knowledge" that we have so far. Without the 19th century giants in the field of physics, we couldn't have progressed this far, but those giants were simply ignorant of 21st century physics. Today we too, are still ignorant to a certain extent, but hopefully less ignorant than 19th century folk.

But authors then said different. They say things that are not agreed to
by author today who no knowing what they are meaning.

Or something like that.

Light may also be treated as photons.

Yes. In one chapter as waves and in the next as particles.

But it means only that you do not know what the light is.

The Giants discovered in XIX century that light is the oscillatory flow of
electrons.

Today we too, are still ignorant to a certain extent, but hopefully less
ignorant than 19th century folk.

In XX century was done the first rectenna: "A rectenna is a rectifying
antenna, a special type of antenna that is used to convert microwave energy
into direct current electricity. "
In XXI century are the optical rectennas.

But the first were the crystal radio:
"The simplest crystal radio receiver, employing an antenna and a
demodulating diode (rectifier), is actually a rectenna".
From: http://en.wikipedia.org/wiki/Rectenna

You wrote "latest theories that support the latest experiments are the best

But there are plenty of theories. Which one is the best?

Every time yet another post on this subject arrives, I can't help
thinking of the limerick about the 'Young man of Devizes' (a small town
in Wiltshire, England). Those who have no idea what I'm talking about
can Google.

Perhaps there's a similar one about a radio amateur whose dipole had
unequal wire sizes?

Oh dear! The Wiki page tells us that a rectenna converts microwave energy
then says, inconsistently, that crystal radios (which operate on MW and LW)
are rectennas.
I think the rectenna was mentioned by Szczepan several months ago - are we
going around the loop once more?

Is it worth commenting about scientific method, theory and fact?
I'll say that reading Szczepan's postings makes a good spectator sport.

But that has since been proved not to be a fact, i.e. their theory has been disproved. Just as Issac Newton's discoveries were a little off, so were the "Giants" about which you speak. In RF conductors, electrons do oscillate but they are much too slow to "flow". I can crawl on my knees faster than electrons flow in a wire and that has been proved by actual measurements. The RF fields/waves that are flowing around a conductor at the speed of light are photons like the ones you are using to read this screen, just at a different frequency. When you realize what is the nature of the thing that is incident upon your retina, you will understand EM radiation.

But there are plenty of theories. Which one is the best?

The one that agrees with the latest experimental measurements. Einstein's theory that gravity curves space was just a theory until proved valid by actual experimental measurements. The CERN Large Hadron Collider is providing actual experimental measurements as we speak. If the measurements disagree with the Standard Model, we will have to change the Standard Model.

To have knowledge means know the facts not theories.

We will probably never know all the "facts" - the best we can do is become less ignorant. All of our models of reality exist in human minds filtered through human senses none of which are perfect. For instance, entangled particles seem to violate the spirit of the speed of light limit, yet they have been proved to exist by experiments. And how is it possible for a huge carbon Buckyball to pass through two slots at the same time and interfere with itself on the other side? Seems to me that the particle is creating a wavefront in the structure of space.

The best models are the ones that best match the latest experimental evidence. Some of yours do not match the latest experimental evidence at all, i.e.. seems that you are deliberately choosing to remain ignorant (or just pulling our legs).

"End-Fed Center-Fed Dipole (AKA Coaxial Vertical Dipole)

Really, that description is correct. Primarily constructed with coaxial
cable the one half wave vertical dipole is fed from its bottom but the coax
shield is left in place only up to near the center point (about ¼ wave but
the exact end point for terminating the shielding is determined by tuning)
which becomes the actual "feed-point" ergo, the description. The center
conductor continues up for about ¼ wave past the point of termination of the
shield." From:
http://forums.qrz.com/showthread.php...ter-Fed-Dipole

Are the wires equal or unequal?
Is it dipole, monopole or "dipole"?

What in the hell are you babbling about with "one chapter" and "next"?

But it means only that you do not know what the light is.

Everyone but you knows what light is.

You are an ignorant, babbling, ineducable idiot who knows absolutely
NOTHING about anything.

How many antennas have you built in your lifetime?

Why do you refuse to answer the question?

Is it because you have built zero antennas and you are trying to say all
the people that have successfully built hundreds that they are all wrong
and you don't want to admit you are an ignorant, inducable, idiot?

Why can't you obtain and read a university level textbook on anything
in any language?

Is it because you are too stupid to be able to understand the material?

The "Giants" were wrong, light is no such thing, and you are a moron.

Irrelevant to anything to do with the nature of light.

From: http://en.wikipedia.org/wiki/Rectenna

Irrelevant to anything to do with the nature of light other than to show
light and radio waves have the same properties.

You wrote "latest theories that support the latest experiments are the best
"knowledge" that we have so far".

But there are plenty of theories. Which one is the best?

Generally, the latest ones which have more experiments and data to back
them up.

To have knowledge means know the facts not theories.

To be Szczepan Bialek means to be an ignorant, ineducable, moron.

You are an ignorant, babbling, ineducable idiot who knows absolutely
NOTHING about antennas or how they work.

You don't even understand what an antenna is or the difference between
an electric field, a magnetic field, and an electromagnetic field.

An antenna is a device that converts the AC electrical energy at it's
teminals into electromagnetic energy which radiates from the antenna
and also coverts the electromagnetic energy which antenna intercepts
into AC electrical energy at it's terminals.

A rectenna is simply an antenna with something that acts as a diode at
it's terminals to convert the AC to DC.

How many antennas have you built in your lifetime?

Why do you refuse to answer the question?

Is it because you have built zero antennas and you are trying to say all
the people that have successfully built hundreds that they are all wrong
and you don't want to admit you are an ignorant, inducable, idiot?

Why can't you obtain and read a university level textbook on anthing

They jump off from the end (corona) after the time equal to speed of light.
They do not flow from the transmitter to the end of antenna. They kick the
next ones. It is the oscillatory flow.

In textbooks are Heaviside's and Pointing's EM. Are They Giants?

Hertz did the experimental measurements of waves from the dipole
(polarisation, refraction etc.)
Do you know something about the Marconi antenna?

The papers of Giants are now available. Try to compare the papers by
Heaviside-Pointing and Dirac.
Dirac was an engineer so he was tought on Heaviside-Pointing's EM. Dirac
never even mentioned EM.

Ia trying to pull you from the textbooks (where all is simplified) to the
paper of Giants.
