Hi all
Walt is not espousing a theory
Please, give me a name to name it.
Hi Miguel,
Walt is presenting data to support a hypothesis (explanation for the
occurrence of some specified group of phenomena).
They have what is called "internal consistency."
Who are "they", Walter's propositions?
Models have what is called "internal consistency."
Before advance more Richard. All off you share or ascribe a
"existence" notion determinated by observator measurements? It is long
time philosophical question remember, trees, sounds...
You are getting into intederminancy. Is this more about Truth again?
Truth is funny and sad, but not very useful.
A confused statement
I know. Communicate minds takes its time. It is more easy as we share
the basic assumptions neccesary for that. It's what I'm trying.
-------------
Two light waves can pass through each other at the same point in space without affecting or interacting with each other because they are *not collinear*.
You don't need "because" or anything that comes after it. It sounds
like superstition.
Why? As I learnt superposition principle not depends of collinearity.
English Oxford dictionary I have, define "Interact" as "act on each
other", similar concept in spanish I think. I learnt superposition as
involving 'no interaction'. both waves still identical to itself in
superposition (in nonlineal systems they certainly can interact).
Yes.
For pure sinusoidal waves, the transmitted wave, the re-reflected wave, and the constructive interference wave are all coherent and collinear and merge into a single forward wave flowing toward the load. The component waves become inseparable.
More superstition. There is nothing about sinusoidal waves that make
them coherent or colinear. This is probable a problem of poor English
from a native speaker - very common.
I can agree with above paragraph but, for that I just said, I think
not with this...
Therefore, any two coherent RF waves traveling in the same direction in an RF transmission line, will interact and have a permanent effect.
Permanent - another superstition (until the end of time + 1 day?).
As I undestand, two o more superposed waves can be added or
substracted to render a resultant but we do not call that interaction
(I am excude here the observer -Richard's observations- notion for not
to get out of point).
Two traveling waves with same direction, frequency and phase would be
certainly indistinguishable of a single one equal to the vectorial sum
of the two cited, by our instruments. For my conceptual notions adding
or substraction are not interaction.
They interact on the load, not on each other. But as you now phrase
it, being colinear as an initial condition rather than as a subsequent
result, then the possibility of both sources (acting as opposing
loads) cancelling each other may follow.
This says nothing of waves interacting, however. That is sheer
nonsense.
Let's put it another way and agree entirely! Accept that two coherent
waves that are colinear do interact - but only if colinear. That must
be some very, very special mathematics that allows no error in
colinearity (perfection is demanded). Perfection does not exist, the
necessary colinearity does not exist, interaction does not exist.
OK, so near perfection is suitable. -sigh- How much is "near
perfection?" Within one millirad? What is it about 1.000001 millirad
that extinguishes interaction? Oh, 1.000001 millirad works too, but
not more. OK, what is it about 1.000002 millirad that extinguishes
interaction? Oh, 1.000002 works too, but.... Pretty sloppy argument,
I don't see a formula for when interaction stops working, this means
that all angles cause interaction, but we do not see interaction at
any angles.
This "take it on faith" kind of creation (create it as you go) science
returns us to vaudeville (Miguel, maybe I should use the term Commedia
dell'Arte to explain our vaudeville).
"God said let there be a photon... go forth and multiply"
[- low budget creation science definition
for the Sun(s) taken from the first printing of
"How to Kick Start Genesis on One Quanta a Day."]
(Adam, muttering) what a day.... what a day.... (suddenly inspired)
What a beautiful photon-set we are having this, this, this. I think I
shall name this "evening" Eve! What a beautiful photon-se.... Damn!
(whoops - oh I beseech thee to forgive my utterance) it got dark
quick. How long before photon-rise? Are we on photon savings time?
Suppose we are not capable to
perceive any light (or realize of it), only HF spectrum; could you
share (agree?) concepts with our other "blinded" colleagues :) to
analize this stuff?. I believe that is absolutly a "Yes" (of course
you could use your knowledge in optics to devise good RF arguments,
but you have to silence it, because you know they "antenna senses" are
note light sensitive.
Lost in the bushes again.
