One might wish your reasoning on this held true, but I'm afraid it is not
that simple. You have over looked the possibility that anyone smart enough
to understand the depth of the theories involved, probably has the social
graces of a leper, having spent his evenings in intensive reading in
private, rather than polite social intercourse.

"Ad hominem" is a much overused phrase. If someone assert something

I take it that you acknowledge that Henry Wilson, Ken Seto, Logicalpike,
Eleaticus, Len Gaasenbeek (sp?) and others of their ilk, aren't deserving
of any consideration since they all go out of their way to viciously
insult those with whom they disagree (i.e. they insult those people who
have actually taken the trouble to understand the theory). The fact is
that the above-mentioned loonies don't care about understanding the
theory, and they actively ridicule any attempts to help them understand
the theory, and they will typically defame those kind people who try to
explain the theory to them. The fact that they absolutely refuse any
help in understanding the theory means that they are not worthy of the
"educate, not ridicule" policy, since such a policy is completely wasted
on them. Eric, like many of us, has no doubt attempted "educate, not
ridicule" with the people I've listed above, but he has wisely dropped the
policy with them because of their continuing offensive behaviour in
response to help proffered to them.

That is what adopting an "explain" policy with Wilson, Seto, Logicalpike,
Eleaticus and Gaasenbeek is akin to: hitting one's head against a brick
wall. Why should one choose to continue such an unproductive course of
action?
David McAnally
In fact, I've attempted on many occasions to explain and help, but I have
met with continual abuse from at least four of the above-named, with
downright abusive defamation from at least one of them for merely trying
to help him, so I know what I'm talking about - because I'm speaking from
experience.
I have also been insulted by Kolker, for which he still owes me an
apology, but that's a different matter - I am beginning to wonder if Ken
Seto may have been right after all in supposing that Kolker believes that
the perceived pitch of an approaching source increases as it gets closer.
Of course, such a belief would be erroneous, but Kolker actually quoted a
bit of a website which could be consistently read with his holding such a
belief.

Ah yes, your ridiculous claim that the frequency of a far away object is
lower than the frequency of a closer object. Well, I heard a dog barking
in the distance recently, and you know what? It sounded like it was
exactly the same pitch as a dog close up - only softer because it was
further away. This observation directly contradicts your claim regarding
frequency decreasing with distance (since pitch is an artefact of
frequency alone), so your entire view on frequency is demolished on a
simple observation of a distantly barking dog.

Only because there is no difference at all, except in your overly fertile

Absolutely. Let all tree top shouting go without a return challenge. Eschew

before you return one.
But that's just my suggestion of one possible path to behave as a

I take for sure you never visited any concert of any kind because there you
will experience a dropoff in the high register frequensies rather fast if
youre leavin, while the low frequent sounds can be heard miles away.
If it depends upon that the lowfrequent sounds carry more energy from the

send signals over great distances, and whales have sound at a frequens

Dirk Vdm
===In addition it is always necessary to take into account attenuation due
to the absorption of ===sound by the air, which may be *substantial at
higher frequencies*. For ultrasound, *air ===absorption* may well be the
*dominant factor in the reduction*.
*** 6.10 What is the doppler effect?
When a sound source is moving, a stationary observer will hear a frequency
that differs from that which is produced by the source. The doppler effect
will be noticed as a marked drop in pitch when a vehicle passes at high
speed. An interesting fact is that doppler for any straight line movement
always sweeps down in pitch!
If one approaches a sound source by moving toward it with a velocity, v, the
frequency of the sound heard is F=Fo(c+v)/c, where Fo is the emitted sound
frequency, c is the speed of sound in still air and v is the speed of the
observer or the moving source. if one moves away from a sound source, the
sign of v is reversed.
But for an approaching sound source, the frequency of the sound heard is
F=Fo*c/(c-v). For a receding source the sign of the velocity, v, term is
reversed.
The speed of sound in air is approximately 340 m/s (see 2.11).
Example 1: A sound source, S, emits 1000 waves per second (1 kHz) and is
moving directly towards an observer, O, at a speed of 100 metres per second
(equivalent to approximately 225 miles per hour).
After 1 second the wave front, which is travelling at the speed of sound,
will have travelled 340 metres from the original source position. Also after
that second the sound source will have moved 100 metres towards the
observer.
0 m 340 m
S | | | | | | | | | O
<-------------- 1000 waves ------------------>
100 m 340 m
S | | | | | | | | | O
<------- 1000 waves --------->
Therefore the same number of waves will occupy a space of 340-100 = 240
metres and the wavelength will be 240/1000 = 0.24 metres. To the observer
the frequency heard will be the speed of sound divided by its wavelength =
340/0.24 = 1416.7 Hz.
Example 2: An observer moving at 100 metres per second directly approaches a
stationary sound source, S, which is emitting 1000 waves per second (1 kHz).
In this example there is no change in wavelength. In one second, the
observer will hear the number of waves emitted per second plus the number of
waves which s/he has passed in the time (1000+100/0.34) = 1294.1 Hz.
Note the interesting result - a stationary observer with moving source will
not hear the same frequency as a would a moving observer with a stationary
source.
Interesting corollaries are that if one is confined to movement velocities
equal to or less than the speed of sound, on approaching a sound source, one
will observe frequencies up to only twice the radiating frequency, but if
one is stationary and approached by a sound source, there is no upper
frequency limit.
Thought teaser: Apply these principles to light, aether, red shift and
quasars. What would cause a "blue shift"?
*** 2.9 How does sound decay with distance?
At distances large compared to the size of the source, sound intensity
diminishes according to the inverse square law.
I = Io/D^2
It is relatively simple to reliably calculate provided the source is small
and outdoors, but indoor calculations (in a reverberant field) are rather
more complex.
If the observation position is at a distance that is small compared to the
size of the source, sound level changes very little with location. One
should be able to determine the "virtual center" of the whole sound field,
whence inverse square law calculations can proceed in reference to that
distance.
The surrounding environment, especially close to the ground and in the
presence of wind and vertical temperature gradients have a great effect on
the sound received at a distant location. Ground reflection affects sound
levels more than a few feet away (distances greater than the height of the
sound source or the receiver above the ground). Wind and air temperature
gradients affect all sound propagation beyond 100 meters over the surface of
the earth.
If the noise source is outdoors and its dimensions are small compared with
the distance to the monitoring position (ideally a point source), then as
the sound energy is radiated it will spread over an area which is
proportional to the square of the distance. This is an 'inverse square law'
where the sound level will decline by 6dB for each doubling of distance.
Line noise sources such as a long line of moving traffic will radiate noise
in cylindrical pattern, so that the area covered by the sound energy spread
is directly proportional to the distance and the sound will decline by 3dB
per doubling of distance.
Close to a source (the near field) the change in SPL will not follow the
above laws because the spread of energy is less, and smaller changes of
sound level with distance should be expected.
In addition it is always necessary to take into account attenuation due to
the absorption of sound by the air, which may be substantial at higher
frequencies. For ultrasound, air absorption may well be the dominant factor
in the reduction.

I have actually been to many concerts, but I don't leave before the
concert is completely finished. I'd consider leaving before the concert
finishes extremely rude behaviour and bad manners. But if you choose to
exhibit rude behaviour and bad manners, that's your look-out. You would
appear to do it all the time, going by your comment.

Whether or not this is true is irrelevant. It's not what Seto claimed.
Seto claimed that the frequency of a wave actually decreases as it gets
further away from its source. He made no comment about attenuation.

Well, at least this contradicts Seto's ridiculous assertion that perceived
frequency increases as the source gets closer.
If you ever thought that you were writing in support of Seto, then you're
wrong - you're contradicting him all the way.

It wasn't supposed to revealing. since revelation is philosophy,
which is exactly what the nonexistent Doppler Effect is.
We were talking about siren and now you want to talk about barking dog??
That's OK. Now tell me when the dog was very far away you didn't hear his
barking at all right?? What does this mean? It means that the received
frequency is zero. Now when the dog get closer you heard him barking. That
means that the received frequency is not zero. That also means that the
approching dog's barking was increased from zero frequency to non-zero
frequency. This also means that the frequency start of low (zero) and
increased to a max level. This is exacvtly what I said. This is also exactly
what we hear from an approaching siren.

Only a stupid mathematician can't see the difference. The difference is as
follows:
If the speed of light is a universal constant:
1. The light path length of a rod (300,000km long) must be the same in all
frames of reference.
2. The absolute duration of a clock second co-moving with the rod must be
the same in all frames of reference.
If the speed of light is a constant math ratio:
1. The light path length of a rod (300,000km long) is dependent on the state
of absolute motion of the rod.The higher is the state of absolute motion the
longer is the light path length. Identify this light path length as
gamma*300,000km
2. The absolute duration of a clock second co-moving with the rod is
dependent on the state of absolute motion of the clock. The higher is the
state of absolute motion the higher is the absolute duration for a clock
second. Identify this absolute duration as gamma*1 ether clock second.
3. The term gamma cancels out and the math ratio for light speed remains
constant in all frames.
Ken Seto
No it doesn't contradict with what I said. It contradict with what you said.
You said: the pitch of a siren remains relatively constant during the
approaching leg and that the increase in volume of the siren is due to its
loudness. Clearly that is not what is observed with an approaching siren. .
>

You are full of shit. If the approaching source is very far away the
receiving frequency is zero. As the source get closer the receiving
frequency is not zero. That means that we have an increase in frequency as
the source is approaching the receiver. This is supported by the increase in
pitch of an approaching siren. This is exactly what I said.
Ken Seto
No it is not irrelevant. It proved that you were wrong.

What is "the frequency of a wave"? However the frequency of a source does
decrease as it gets further away from the receiver. In fact when it get too
far away the receiver will receive no frequency (wave/sec.) at all. Unless
you are a moron you would recognize that means that frequency decreases as
the source gets further away from the receiver.

Radar guns work like any other gun does,

It is not a Top Secret, since it's not even a secret.
Engineers keep telling physicists that they work for the same reason
*TODAY*
as they did *YESTERDAY*, the *DAY BEFORE*, and 10,000 years ago.
And that reason is that scientists are CLUELESS of WORK.
You just have to ask yourself: what does it matter? If educating
won't help them, ridicule certainly won't! But education does help
others following the thread, which ridicule does not. And you have
absolutely nothing to gain by trying to defend your honor when these
people ridicule you because neither you or the crowd of, *ahem*,
"alternative thinkers" will be fooling the readers of
sci.physics.relativity. If Ken Seto says you're an idiot, I will
assume you said something he disagrees with, but not that you were
wrong or that you're an idiot. That judgement comes later after I'm
more familiar with your own opinions.
"Don't lower yourself to their level" actually works surprisingly well

That is an answer, since "scientists" don't even ask questions,
they merely have this recursive gibberish word-game going
with non-existent Dope Effects and enlighment from GAWD.

I agree with Dirk.
But I shouldn't be too surprised that Seto couldn't even pick up that I
was commenting that Thornvall was contradicting him (which is true), and
that I had made no comment about whether reality contradicted him.
I stated that Thornvall had contradicted Seto, and in denying this, Seto
made absolutely no reference to what Thornvall had written, but Seto
instead brought up his individual beliefs about reality, which were
irrelevant to my comments.

Hey stupid mathematician. The following comments from Thornvall support my
claim that the frequency decreases with increasing distance:

you

youre leavin, while the low frequent sounds can be heard miles away.
If it depends upon that the lowfrequent sounds carry more energy from the

Is there no limit to your stupidity? So you think that going from zero
receiving frequency when the source is far away to something greater than
zero frequency is not an increase in frequency due to distance??

Dear David,
It is not quite that simple. Some of the Relativity experts do let the
taunts of others get under their skin, and will fight fire with fire and
deal well with the meat of the issue in the same posting. However, the
quality of a posting is inversly proportional to the amount of ad-homium
material in it, and a poster can easily be judged by the amount of ad-homiun
material they produce. Those who have something worthwhile to say spend
less of their energy taunting and baiting others and responding to that same
sort of stuff.
The same also applies to threads and subthreads. In general, once a thread
has degereated to name-calling, it is time to kill it and look elsewhere for
worthwhile material.

Hey moron, I'll ask again: If I want to hear beethoven's sonata in
c# minor played in A minor, how many rows back from the piano do I sit?
How about if I just want to drop it an octave?
Lower frequencies have larger wavelengths. A basic principle of wave
mechanics is that a wave doesn't interact wit things smaller than
about half its wavelength, so there is less stuff that interacts with
and scatters the energy of lower frequencies.
So you admit that you were unaware that Doppler effects are OBSERVED
by engineers, which you didn't know because you don't know anything
about engineering.
High frequencies are more easily absorbed than low frequencies.
That is why an approaching source with a broad frequency range
sounds higher *but a bit weaker* than a receding source: the latter
sounds lower *and a bit louder*. The drop in loudness is caused
by the filtering of more high frequency waves.

A few weeks ago I posted the formula for Doppler shift as
observed by someone who is not on the line of motion of the
source, i.o.w. with what you call 'angular approach'. I haven't
found the formula on the internet, so I had to derive it myself.
It's not difficult.
Observed frequency of a moving source:
f = f0 * s / [ s + w*sign(x) / sqrt( 1 + (a/(wx))^2 ) ]
where:
f = observed frequency (pitch)
f0 = real frequency (mono, not a range!)
s = speed of sound
w = speed of sound source
a = distance of observer to line of motion
x = distance of source to nearest by point on track
if x < 0 (approach), the formula becomes
f = f0 * s / [ s - w / sqrt( 1 + (a/(wx))^2 ) ]
if x > 0 (receding) it becomes:
f = f0 * s / [ s + w / sqrt( 1 + (a/(wx))^2 ) ]
Look at the drawing:
http://users.pandora.be/vdmoortel/dirk/PickUp/Doppler.gif
As you can see: the frequency constantly drops. It is greater than
the emitted frequency on the left of the vertical (approach) and
lower on the right side.
If you are on the line of motion (a=0), then the horizontal lines
show the result: a sharp drop when the source passes your ear.

Well, David, that is an interesting point. There's quite a bit of
stuff about to convince a rational man that what we call mainstream
science is mostly pseudoscience when it comes to commonly accepted
'theories' about how the universe works. Many of the advocates of
mainstream views actually insist that science has nothing to do with
the pursuit of Truth and, in fact, such persons who themselves are
devoid of truth will insist that truth is not a goal of science. I'm
only left to wonder who it is that they suppose died and left them in
charge as to how to define the ideals of scientific enterprises. I
encourage people to at least read Rene Descartes 'Rules for the
Direction of the Mind' where he is critical of the rampant
pseudoscience that attempted to pass itself off as legitimate science
in his day. Most people are unaware that not much has changed but the
date on the calendar. We've made many technological advances but not
all of those can be directly attributed to the notion that we have
operated with clear ideas about the nature, structure, relationships
and dynamics of the components of the universe. Building a
succeessfully working cell phone bears no relationship at all to the
idea that accepted concepts on the operations of stars have anything to
do with how they actually work. In other words, success in technology
generation does not insure that we have even a close handle on how the
universe works.
So, when I see people advocating some mainstream idea which may have
enjoyed univeral acceptance and popularity for fifty years or more but
which cannot be substantiated by any experimental data then I think I
have the right and duty to point out the rampant pseudoscientific
processes which allowed such ideas to develop and proliferate.

Actually, the confusion is probably because you didn't really believe
anyone would make the claim seto did. seto believes the doppler shift is
related to the distance of the source. Sane people realize the velocity
is resonsible and the fact that the source gets closer or further away
is an artifact of "moving" at some relative velocity, by definition of
what "moving" means. A quote from seto, message id:
<3c803a29$0$1598$4c5e...@news.erinet.com>
"So you think that going from zero receiving frequency when the
source is far away to something greater than zero frequency is not
an increase in frequency due to distance??"
Note the confusion between an increase in the amplitdue of a
particular frequency and an increase in frequency.
No engeneer is this ignorant about basic physics.

Intensity = waves/unit area
Frequency = waves/unit area/unit time
Intensity is dependent on the distance between the source and the receiver.
It is natural to conclude that frequency is also dependent on the distance
between the source and the receiver.

Playing word games again eh Paul? When the Great Dane is far away the high
frequency components interact with the medium and disperse while the low
frequency component is able to reach the receiver. When the Great Dane is
close by both the high frequency components and the low frequency components
are able to reach the receiver and thus the receiver detect a higher
frequency.
Ken Seto
Eric Prebys, Henry Wilson has drawn my attention to the fact that you have
been using my name without permission and in a derogatory way on this
newsgroup. If you do not cease immediately and apologise, I might be
inclined to take further action.
I have a computer business to run. Amongst other things, I set up web pages
for other people. Henry just happens to be one of my clients as well as an
old friend.
I used to take part in this Newsgroup but realized long ago that it was a
total waste of time arguing with indoctrinated people like yourself.
While you're at it, sue me, too, since it takes a lot of gall to give
someone as irrespnsible as henry the use of your internet account and
free run of your web site (btw, what does your isp say about this) and
then try to shuffle off the blame for the confusion you caused on someone
else. (Provided I make the assumption that you and henry really are
different people for the sake of argument). You should feel fortunate
that henry didn't pull his stunts in a newsgroup that takes a dimmer
of view of of those antics.
Oh. And sue henry, too. He was crediting you for helping him program.
Given the answer he gave me to why the recursion relation for the
bessel functions J_n(x) does not give an accurate value for J10, given
J1, you might say that he defamed you.

Don't be a moron. Doing so publicly reduces the credibility of
your legal threats from merely impossible, to absurd. The standard
for defamation here in the US requires that (1) the statements are
false, and (2) proof of damages. (3) Anyone that would spend the
money required to press a frivolous lawsuit they can't win, based
upon being defamed by a usenet article, will have a hard time explaining
to the court that they really aren't stupid.
In the meantime, you might want to research your case at the
cornell law library, where you will find the us civil code and
terms such as "summary judgement".

It's no one's fault but your own that you put henry in a position
put you on the short end of his irresponsible littering of sci.physics.*
with his illogiacal, repetitive diatribes. If henry is a client, why
is he using your website? I'd speculate on this, but I'll save it for
another lawsuit.
>I used to take part in this Newsgroup but realized long ago that it was a

Why is it that this sounds like one of henry's clichès? Not only
that, nobody but henry would be so stupid as to try and obtain an
apology for some imagined insults by insulting the person to whom the
threat is addressed.

Gee, Eric, I wonder why anyone would think that "Henry" and
"Rabbo" might be the same person. Leaving aside that they both
are totally clueless about physics, note the following.
"Rabbo": "45 yrs experience in applied physics."
"Henry": "I have been a physicist for 45 years."
"Rabbo": "I just happen to be a physicist/mathematician with an
extra degree in psychology and genetics."
"Henry": "I have a full degree in physics and maths...I also have
a completely separate science degree majoring in psych and
genetics ."
So "Henry" and "Rabbo" each happen to be physicists and
mathematicians who worked in the field for 45 years, and they
both also have degrees in psychology and genetics. And, the
headers of their posts both bear the imprint "Organization:
Customer of Telstra Big Pond Direct." What an amazing
coincidence!

"Henry Wilson" is incredibly ignorant of physics, and I suspect

Actually, I wasn't insinuating that; I was saying it outright, but

That's not a sufficient explanation. It is rare, if not unheard of, for
two contemporaries to take *exactly* the same courses as university to
that extent. So please tell us: which University did you attend, what
degrees do you have (and from where), and what papers have you published
(and where were they published - i.e. in which refereed journals were they
published) in your stated 45 years as a physicist. Also, what papers have
you published as a mathematician, and in which refereed journals?
