Default what happens to reflected energy ?

Hi hi, Why I find it more hard to translate your writings than another
guys ones? is it a peculiarity of your playing with words or your zone
manners? I am sorry because I miss some of your subtleties or
grammatical tricks and I suspect they have more funny meanings that I
can capture :)


Hi Miguel,

Sorry for the loss in translation. It is what is called "deep
metaphors" that go beyond the simpler ones of mosquitoes against the
windshield.

I believe what we have more here are psychoanalysts not psychiatrists
(I read something about it time ago), but do not worry I am a little
crazy too! :)


You are correct (about analysts...).

Here, the game of language is found in the ellipsis (or the
parenthetical aside - this one being doubly self-referential).

Look, my first idea example was compare difference in marbels size
with hydrogen atom size (about 10^8) to point to granularity, but
inmediately I realized that dealing with differences in size was not a
correct example and turn to Ec example. You said our retinas sometimes
can perceive individual light photons, no?


Yes, in the best of circumstances half of those that impact the
retina. This returns us to background noise and S+N/N.

then I pointed to an eigty
meters photon had 10^-8 smaller energy than green photon.


Hence the eight orders of scale comparison. Yes.

I was telling we are talking about truly classics system therefore
quantum effects (photon) it is useless because in our level of
discussion oscillators/transmitters do not manifest quantum effects
because its very high quantum numbers Of course I know (do I know?,
really?, mmm) correspondence principle.


You can experience one photon, however could you state that it was not
two instead? I have designed with components that are specifically
photon counters. These are called photomultiplier tubes (PMTs for
short). Where they do not match up against the eye for dynamic range,
spectral bandwidth, or quantum efficiency; they do present us with
individual events within a group. Our eyes do not count very well.

Why at room temperature? Do we see if I understood your question... at
room temperature because we Hams usually make our TL Bird Truline
measurements at room temperatures. Answer this your question? (my
freezer do not go beyond -20 Celcius degrees!).


So, I am to understand that you want to measure quantum effects at
energy background levels in excess of 0.04 eV or roughly 10 TeraHertz.
I don't think you can afford the Bird plug for that band.

I come from a field called Metrology. This is so rare that many, many
engineers have never heard of it. It is the science of measurement.
If you want a quantum correlative to frequency, this field abounds in
them. The Atomic Clock (Cesium Beam Standard) comes close, but the
Josephson Junction is a direct translation of frequency to voltage. It
is also an instrument in quantum computing.

I will offer a page for your consideration:
http://www.ptb.de/en/org/2/Inhalte/J...n/_josephs.htm

Anticipating your objection that the frequencies involved are not in
the 80M band; I would offer that is satisfied easily through frequency
multiplication. (The Atomic Clock does this in reverse and no one
complains about that.)

Anticipating your objection that this is not done at room temperature;
true, the junction is cooled far below what is available to you - but
is this about your limited resources, or is it about being done? Don't
join the legions pleading destitution (poverty) as that might migrate
into the metaphors and analogies for a very poor (sorry for the pun)
outcome.

Theorical/extreme
cases are welcomed too but... to rebut normal/standard situations?
I do not believe you has blocking Cecil posts, no no, you say it = we
have a lot of psychoanalysts he one of them are whispering to my
ear just now, you really like him, remember TV series: "The odd
couple"? :D


Yes, I do block him. There are traces that sift through the cracks,
but that doesn't elevate them to poignancy. Again (do I have to
repeat this?), this is about S+N/N.

"The Odd Couple" is a good cultural reference. I would suggest (and I
hope you have access to) "House." Cecil is among those who cannot be
trusted to write on the white board.

If you don't have TV access to this series, try an episode from:
http://www.hulu.com/search?query=house&st=0
You write and understand English quite well, but if listening to it is
not easy, I am sure that watching 10 minutes around that white board
will give you enough "body language" to translate the psychology
easily.

.....
(You see?, I'm lost with some interesting sentences such "However your
VSWR may vary, no Standing Waves were interfered with in the making of
this response." If tomorrow I find my london friend I ask his helping
to translate better your entire post :) )


This might be lost on your English friend too, because it constructed
with cultural references (it is suppose to be bad form to have to
explain a joke - but here we go):
"However your VSWR may vary"
is a variant on YMMV that you may see as shorthand. It means Your
Mileage May Vary. It is a reference to how car gas performance was
reported by those who sold cars. They would quote government tests
that were generally optimistic, and the real experience would
disappoint customers who saw poorer results. The customers would
complain to the vendor. Thus the vendor would qualify with "the
government reports this car gets 50MPG on the Highway - but your
mileage may vary." Thus the usage of YMMV is a cultural joke
indicating disappointment was likely.
" no Standing Waves were interfered with
in the making of this response."
is a variant on the disclosure you see at the end of movies:
"No animal was harmed during the filming of this movie."
You will, no doubt, draw out the meaning of Standing Waves,
interference, and response as being related to soothing those people
who cry uncontrollably when they see the movie "Bambi." We have a
similar class of sob-sisters (your English friend should be able to
translate that).

73, and now being 23:31 I will take my girlfriend LU2ET to a night
trip motorcycle by the city. Well... 2ET has been my XYL for over
thirty years :)
Have you a really nice motorcycle as Cecil? eh?


I drive an engineer's car with a rotary engine (pistons suck): Mazda
RX-7.

However, you would probably like House's ride.
