Abstract - An experiment is described showing that a 33 GHz microwave
signal received by rotating antennas is not exhibiting the frequency
shift ("transverse Doppler effect") predicted by the relativistic
Doppler formula. The sensitivity of the apparatus used has been tested
to be sufficient for detecting frequency shifts as small as 10-3 Hz
which corresponds to the value of (v/c)2 = 5.10-14 used in the
transverse Doppler shift experiment reported here. From the observed
absence of the transverse Doppler shift it is concluded that either the
time dilation predicted by the standard theory of special relativity
does not exist in reality or, if it does, is a phenomenon which does
not depend on relative velocities but may be a function of absolute
velocities in the fundamental frame of the isotropic microwave
background radiation.
Can that be true?
Are there measurements that show the transverse Doppler?, e.g GPS.
One thing is clear, that many effects can be explained by use of SR,
e.g lifetime of muons.
I don't know any source that can explain this with Newton.
Also there are effects, like Sagnac, that can be explained with SR and
Newton.
But let's say it with Sir Popper: truth has to be confirmed if still
true.
At the moment I'm not sure how to proceed.

The experiment doesn't show that a *real* incompatability
exist with Maxwell's equations and Galiean relattivity
rather than an apparent one. IOW resolution of the two
postulates. While it may shake the foundations of
a few H.G. Wells fans that were reading too much
into to the thought experiments it doesn't seem to
suggest the need to derive time dependent field
equations any differently than we now do.

Simple. If it violates *GR*, then it's interesting.
SR only works within inertial reference frames; if gravity
or spinning is involved, it gives up and goes home. :-)
Since you mention rotating antennas this is probably a Sagnac

xxein: Please show some sort of proof for that statement.
His "proof" is simple. Muon lifetime is known, distance is about
100 km; therefore v = d/t = 150 times lightspeed. That's the
gist of Androcles' "proof". (The error therein is left to
the interested reader, although Dirk probably already knows
what it is; certainly *I* do. :-) )
There is a catch. Ground-based muons also have energy; on
average about 2 GeV. Since muons at rest have m_mu * c^2 =
107 MeV, the measured energy is too small by about 600 x.
This means, of course, that Androcles, world-renowned
scientist and mathematician, has discovered, along with
Planet Androcles circling Beta Persei (aka Algol), a
particle that is exactly like a muon only much lighter --
m_mu' * c^2 = 178 keV.
OR
the muon gives up most of its energy to the air upon transit
(I lack data on this one but other research suggests that the
pion creating said muon is about 6 GeV, and 2/3 of the energy
is lost in the atmosphere. Since this is easily measurable
in a cloud chamber I don't see much problem in doing it, although
I might have a problem googling it.)
OR
the muon is experiencing a gamma contraction of about 150, which
is just enough to squish its subjective transit distance to
660 m. (There are discrepancies, yes, again because of said
atmosphere.)
Other measurements are possible and indeed already have been done;
a simple one would be measuring flux of incoming muons while
traveling in an airplane. Also, high-speed muons are creatable
in a storage ring.

TIME DILATION
Vertner Vergon
ABSTRACT
We examine time dilation as set forth in Einstein's paper and find it
has an inconsistency and a reductio ad absurdum. We ascertain a correct
time variation and illustrate its viability.
There is always an open question as to the accuracy of Scientific
articles. So the question arises, how can we judge the accuracy of an
article that involves a theory?
Firstly, the article (theory) must be consistent both internally and
with empiricism. If it isn't it is flawed.
Secondly, it must not violate any known physics laws. Nor, obviously,
can it lead to a reductio ad absurdum.
Theories necessarily contain speculation - else they are not theories
but simply logical constructs. Such constructs must also meet the above
requirements.
Articles generally contain both theory and reference to facts (such as
experiments). These must be verified.
If an article ( or theory) meets these requirements it cannot be
rejected. If it is, it is done so out of sheer obstinancy and/or
stupidity.
Let us examine the concept of Time Dilation as contained in the Special
Theory of Relativity.
We start our examination of the time dilation concept by going to its
source -- Einstein's paper, On the Electrodynamics of Moving Bodies. We
refer to his gedanken experiment of moving clocks. One of two
synchronized identical clocks remains at rest while the other moves
away and returns. When Einstein perceived the difference of the clock
readings in his calculations, he stated the moving clock "was slow by
...". The immediate perception by the public was that he meant if a
clock was "slow by" - it had to have run slower. He also said the
moving clock was "behind" the inertial clock by ... . These two
statements do not mean the same thing. If one clock is running slower,
then it is running slower, and that has only one meaning.
On the other hand to say one clock is behind the other is open to
alternative explanations, e.g., the moving clock could have traveled a
shorter world line -- or may have traveled faster than observed. In
either case the clock would maintain its normal (proper) rate but for a
shorter duration than the inertial clock and thus be behind. At any
rate the accepted version is that the clock ran slower and thus was
born the concept of time dilation.
This concept is usually presented by an illustration that says if one
were to observe a clock on a fast moving spaceship, they would observe
it to run slowly. It must be emphasized that this running slowly occurs
regardless of the direction or vector of the ship. That is to say it
matters not whether the spaceship is receding or approaching, time runs
slower. Also to be emphasized is that this slowness of time is not just
a matter of observation but actually takes place -- for when the clock
returns it is actually 'behind" the stationary (or Earth) clock.
Since this is the declared case, we are inevitably drawn to only one
conclusion, the moving clock has to be running slowly in its own
coordinate system. Here we are faced with an unforgiving contradiction
for basic relativity states that all clocks keep proper time in their
respective coordinate systems. It is inconsistent that a clock can
actually run slowly in its own coordinate system - and also, the
while, keep proper time; in short the clock would have to keep two
different rates simultaneously, a reductio ad absurdum. This
contradiction requires that the time dilation concept, i.e., t' = t
sqrt(1 - v2/c2) be discarded.
The question arises, is there something to take its place? The answer
is yes.
To lay the foundation for this replacement we note that any known
constant frequency is a clock. The scientific community has chosen the
excited cesium atom as the standard atomic clock. This is an arbitrary
choice. Next, we note that the cesium clock (or any other constant
frequency atom) will never vary in its rate. So they will always keep
proper time. However, observations of these clocks will show a
variation due to the Doppler effect. We declare this variation in
frequency is a variation in observed time. Since the frequency is a
clock, an observed variation in the frequency is an observed variation
in time. Call it Doppler or what one will, that is merely a description
of the mechanics. In the final analysis it is a variation in observed
time.
THINGS ARE NOT ALWAYS WHAT THEY SEEM.
Next, we examine a counter argument which states that the relativistic
Doppler rate is the result of the following: If one takes the
non-relativistic Doppler rate and modifies it by the time dilation
they, come up with the relativistic Doppler rate. This, supposedly,
confirms time dilation. Upon further examination, we perceive that even
if we were to accept that explanation, what we have is the situation
whereby an approaching clock is observed to run fast -- not as fast as
non-relativistic mechanics would have -- but fast. This is contrary to
time dilation which requires an approaching clock to run slowly. That a
reversal in direction results in a reversal of time rate is to be
expected since time variation is the result of velocity vectors - and
vectors are directional.
If a theory conflicts with empiricism, it has to be discarded.
Using the Doppler rate as the time rate will yield the time dilation
effect. And that is the proper way to refer to it -- "time dilation
effect". The reason: The net time differential when the movement of the
clock is complete is the same as though the dilation time was operative
throughout.
What then? What is the explanation for the "effect", but not the
actuality? Particle accelerator operators and Ives & Stillwell claim to
have "directly observed" time dilation. What they have observed is
transverse Doppler rates. And it so happens, by some extraordinary
coincidence, that the transverse Doppler rate is the same as the time
dilation rate.
And now to display the Doppler time resolution of the Twins Paradox:
What is displayed here is the round trip Twins experience with no
paradox. The upward arrow signifies outward bound, the downward arrow
signifies inward bound. The double arrows signify the ship being
observed going outbound while it in actuality is traveling inbound.
(second chart). This, of course, is due to the time it takes light to
travel. The observed velocity is v(.75c). At this velocity the so
called time dilation rate is 1/2 . The distance to far-point is sqrt(3
light seconds). So the elapsed time for the ship's transit is one
second due to the fact its actual velocity is sqrt(3 light seconds/sec)
( See The Dual VelocitiesTheory of Relativity.)*
( For seconds or years, the figures hold.)
This means that four years on earth would be only two years on ship.
The time rates shown in the second chart are the time rates of the ship
as observed by earth. They are Doppler rates.
They have to be. Any invariable frequency -- clock or atom -- will be
observed at Doppler rates. The same is true for observations of earth
by the ship (first chart). So there is a parity of rate observations as
required by the principle of relativity.
NOTICE, there is no time dilation rate observed (1/2 in this case) --
but when the trip is concluded the difference in the clock readings is
as though the ship clock had run at half time to the earth clock, i.e.
, run at dilation time. When Einstein saw that in his calculations
(1905 paper) he said the A clock "ran slow" by ... . This created the
impression that time really ran slower for the ship's clock. The table
below shows this isn't so. It runs at the normal (proper) rate but is
observed to run at the Doppler rate.
It is worth mentioning that according to the Special Theory of
Relativity a clock in the approach mode runs slow - but astronomers
observe clocks in the approach mode, and they are running fast.
Consequently, there is no time dilation observed. There is, however, a
time dilation effect, i.e., the transit time differential on the two
clocks -- and these were created by Doppler time.

So we see that although the final time differential is as though time
dilation were operating - in fact it is the Doppler time-frequency
that operates.
Note: Not only is there a parity of rate observations, but the length
of time each twin is an observer is equal to the time he is observed.
Thus there is a time commonality of observation. This, in a space-time
chart given in Space-time Physics (by Taylor and Wheeler), is labeled
the "line of simultaneity".
* To calculate the Astronomer's observation of the outgoing trip,
we note the following: The distance to far point is 1.732 light
seconds. The velocity of the ship to the astronomer is the relativistic
.866 c. Thus it will take two seconds for transit. But Astronomer will
not observe that until light recording that event arrives at earth.
This will take 1.732 seconds. Adding the 2 seconds and the 1.732
seconds yields the 3.732 seconds of observation (upward arrows).
* Regarding the return trip: Even though the ship is traveling at a
(Newtonian) speed greater than c, it does not surpass the light
recording its journey. Instead, the waves pile up (condense) in front
of it and are observed by Astronomer at the rate of 3.732 times norm.
This phenomenon indicates that light can travel faster than c but the
manifestation of that is an increased frequency (shorter wavelength)
- with the observation of c as the velocity.
HAHAHAHA!!!

The transverse Doppler effect is a FACT, it has been fully verified by
the experiments of Ives and Stilwell.
The TDE is a second order effect (an effect in (v/c)^2), therefore it
is VERY difficult to detect. Normally, the experiments detecting it
have a differential setup.
Occasionally claims like this resurface . A retired engineer who
doesn't understand the TDE sets up an experiment incorrectly, detects
nothing and goes around making ridiculous claims.

You can ignore this if you like. This is an unmoderated

Your actions are pretty close to "flaming", which is something
that is not supposed to happen here.
You are altering the titles of the posts, which makes continuity
of posts problematic. Some newsgroup readers depend on the
titles to decide which thread they belong to.
Could you lighten up a little? You've taught them to do the same

This is the paper:
http://ieeexplore.ieee.org/iel5/7883/21718/01007152.pdf
I have read it, and will claim that the experiment cannot
measure the transverse Doppler shift. In fact, according to SR,
there should not be any Doppler shift of the received signal.
To understand what I write below, the reader will have to
read the paper.
The author correctly states that the receiver antennae,
which are at the rim of a rotating disk, should receive
the blue shifted signal f' = f/sqrt(1-v^2/c^2)
where v is the peripheral speed of the rim (and antennae).
This is because the angle phi in the equation
f' = f*(1-(v/c)cos(phi))/sqrt(1-v^2/c^2)
is the angle between the direction of wave propagation
and the velocity of the receiver _in the rest frame of
of the transmitter_. This angle is pi/2 in this set-up.
But the problem is that the detector is stationary,
and is not on the rotating disk.
There is a strip line along the rim of the disk, acting
as a transmitter. A stationary pick-up antenna is detecting
this signal.
The author states:
"The picked-up signal should exhibit the same frequency
as the signal present on the circular rim due to the circular
symmetry of the rotating disk and no further Doppler frequency
shift is expected to occur for the waves being transmitted
from the rotating strip line into the pick-up antenna."
This is clearly wrong. There is a moving transmitter, and
a stationary receiver. In this case, the angle between
the direction of wave propagation and the velocity of
the transmitter is pi/2 _in the rest frame of the receiver_.
The angle phi' in the rest frame of the receiver relates
to the angle phi in the rest frame of the transmitter thus:
cos(phi') = (cos(phi)-v/c)/(1 - (v/c)cos(phi))
combining this with:
f' = f*(1-(v/c)cos(phi))/sqrt(1-v^2/c^2)
yield:
f' = f*sqrt(1-v^2/c^2)/(1+(v/c)cos(phi'))
which, when phi' = pi/2 simplifies to:
f' = f*sqrt(1-v^2/c^2)
Which shows that SR predicts that the two Doppler shifts
should cancel each other.
Thus the experiment does not test the transverse
Doppler shift predicted by SR at all.
Actually, this should be rather obvious. The transmitter
and the detector are stationary to each other.
If the detector should detect a higher frequency than
is emitted by the transmitter, where should all those
extra cycles come from? If SR had predicted such a Doppler
shift, then SR would be inconsistent.
What SR does predict is that if there were a frequency
measuring device on the moving rim of the disk, then
the clock (reference oscillator) of that device
would run slow as seen from the stationary frame.
This frequency measuring device would then measure
a higher (blue shifted) frequency.
(All the cycles transmitted by the stationary transmitter
per rotation of the disk are received by the moving antennae,
but a reference clock on the moving rim would count
fewer cycles per rotation than would an equivalent reference
clock in the stationary frame.)
But this experiment does not measure the frequency
in the rest frame of the moving receiver antennae.

Mr. Thim did acknowledge other experiments that have claimed such a
transverse Doppler shift. So, the question is who do you believe that
has the valid data? Why do you not believe Mr. Thim using modern

Your analysis would violate the very basic principle of Relativity in
which you are secretly wishing for an absolute frame of reference to
bail you out of this one. You cannot change the rules of mathematics
associated with the Lorentz Transformations (plural indicating
symmetrical reverse transform). SR predicts a symmetric result where
only the relative speed matters. Thus, you will have another
f' = f / sqrt(1 - v^2 / c^2)
According to SR, the overall result would be the product of these two
which is
f' = f / (1 - v^2 / c^2)

In your equation above, E' is the energy of the photon
in the observer's rest frame, while v is the velocity
of the observer in the source's rest frame, and p is
the momentum in the source's rest frame.
The crucial point which you probably missed, is that
if v and p are transverse in the source frame,
they are NOT transverse in the observer's frame,
and vice versa.

If phi' is the angle between the velocity of the source
and the wave vector in the observer's frame, then the unchangeable
rules of mathematics dictates that the Lorentz transform leads to
the following Doppler equation:
f' = f*sqrt(1-v^2/c^2)/(1 + (v/c)*cos(phi'))
In this case, phi' = pi/2 and thus f' = f*sqrt(1-v^2/c^2)

Nonsense.
SR doesn't predict a "symmetric" result in two different cases.

Nonsense.
There are two distinct different cases with very different
experimental set-up, so why the hell should SR predict
the same outcome?
In the former case, the radiation is transverse in the source frame,
leading to a blue shift: f' = f/sqrt(1-v^2/c^2)
In the latter case, the radiation is transverse in the receiver frame,
leading to a red shift: f' = f*sqrt(1-v^2/c^2)
If you don't understand the difference, you should look up aberration.
If you don't agree that the radiation is transverse to the velocity
of the rim in the rest frame of the stationary pick up, I challenge
you to explain why it isn't. General babble about symmetry won't do.
You have to address the specific experimental set-up in the experiment
we are discussing.
But you don't know what we are talking about because
you haven't read the paper we are discussing, have you?
Paul
Yes, it does shame them (with some pathological exceptions). Especially
if the title is coupled with a sound scientific rebuttal. It also
exposes them to a google search,.
Quite.
My statement was indirectly a support of what you said.
SR can handle everything in that experiment perfectly,
there is no need to invoke GR.
The reason why the experiment doesn't contradict SR
is that SR predicts exactly what is observed - no frequency
shift of the detected signal.
An outcome which, BTW, should be pretty obvious.
If a frequency shift had been observed, causality
had been violated.
But causality passed the test. :-)

Why do you ask such a silly question when the very posting you
are responding to shows that Mr. Thim used his modern technology
to devise an experiment which doesn't test anything at all?
I don't "believe" Mr. Thim because I have read his paper
and _know_ that his experiment doesn't test what it was
supposed to test.
And I am sure I am not the first one to see that,
it's rather obvious.
But you choose to believe Mr. Thim without having read
his paper because you like his claimed result, right? :-)
Paul
Thank's for response. Will study it.
My basis is very pragmatic. As long as SR, GR and Newton can
predict/explain the
various effects, I will accept it. If some effects can be explained by
more than one
theory, that is o.k.
What I can say as a "retired el. engineer" is, that SR is very limited.
It is based on c=const and inertial movement and that's all.
E.g. I start from here to Sirius with v=0.866c, gamma = 2
Why does the universe in direction to Sirius know, that it has to
shrink acc. to Gamma?
But there is some non inertial movement at start included.
So in reality -what is this?- it does not shrink, it makes only the
impression for the traveller.
Therefore, because v_earth = v_traveller it is the only explanation to
be within SR.
Acc. to the ship's clock the speed was 2x0.866c on arrival=stopped.
So, all is clear for me,but not satisfying. This will hold on as long
as we have no good explanation for the behaviour of light not to
behave like Newton thought.
I'm not so convinced as Androcles, Andocles pls forgive me, because I
like you very much upon
your clear standpoint if correct or not.
I have not studied to date if some of the GR effects can be expained
with Newton, e.g. GPS clocks correction.
Rudi

Caveats:
- in a vacuum
- only two way speed measurements are allowed for verification
Answer:
The question you ask has the answer of "yes". In high speed particle
experiments, where photons are Compton scattered from a high gamma
charged particle beam, the photons are boosted up to e_0 * gamma^2
(depending on angle of exit), and round trip times from emission to
collision to detection are unsurprising at c. Occultations of high-z
objects by the Moon yields a null result... all objects are occulted
apparently simultaneously, even though the sources have non-null and
detectable path-"velocities".
But we have been through this, and your ingrown claw forbids you from
considering that light cannot be ballistic, and agree with experiment.
Your words can be the last. Welcome back to my killfile.

Stop taking cheap shots. My equation above is the same as yours. If
you have to say silly thing like "...v and p are transverse in the
source frame, they are NOT transverse in the observer's frame...",
you do not understand the very mathematics of the Lorentz transform.

Because the Lorentz transform is symmetrical in mathematics and thus
predicts the same outcome for the receiver and the transmitter.

You did not use the Lorentz transform to do the math in the latter
case. You need to understand what the very mathematics of the Lorentz
transform. Forget about SR. It is confusing you.

It sounds like you have already believed in a result very different
from Mr. Thim's. Whatever his result is is rejected by you because
of this belief in you. You are no different from Hammond. Is God =
Guv? Instead of your religion belief of SR, you ought to do just like
Dr. Roberts would have done and go through Mr. Thim's data to point
out his observation error as well as error bars.
> I don't "believe" Mr. Thim because I have read his paper

What is he suppose to test? If moortel predicts 2 pebbles plus 1
pebble equals to 4 pebbles. You go out and conduct the experiment by
adding 2 pebbles and 1 pebble together. The outcome should be 3
pebbles, but you have already believed in the nonsense of 2 pebbles
plus 1 pebble equals to 4 pebbles. So, you reject your own
experimental result.
You may call your approach a fine scholarship, but I would have harsher
name for you.

I challenge you to prove that you understand
the very mathematics of the Lorentz transform
by solving the following problem:
In a frame of reference S, a photon with momentum p is moving
along the y -axis. The angle phi is thus pi/2
p
^
| phi
-----|---------------------------> x
A frame of reference S' is moving in the x direction of S
with the speed v.
p
^
| phi'
-----|---------------------------> x'
What is the angle phi' ?

Which receiver and which transmitter?
There are two sets of them, have you missed that?
Case #1:
We have an emitter A, and a receiver B.
Case #2:
B, which was the receiver in #1, is now the emitter,
transmitting the same signal as it receives.
We have another receiver C.
A and C are stationary to each other, while B
is moving with the speed v relative to both.
Now you claim that because the Lorentz transform is symmetrical,
C must must see the signal from B Doppler shifted by the same
amount as B sees the signal from A Doppler shifted with.
The scenario bellow satisfies the above description:
A B -> v C
If f is the frequency of the signal emitted from A,
B will according to the Lorentz transform measure
the frequency f' = f*sqrt((c-v)/(c+v)) and thus
transmit the same frequency f'.
C will according to the Lorentz transform measure
the frequency f" = f'*sqrt((c+v)/(c-v)) = f
Thus the Lorentz transform predicts that C measures
the same frequency as is emitted from A.
And that is also what a real experiment would show,
if it didn't, we would have a causality violation.
The scenario above is obviously different from that
of the experiment we are discussing, because the velocity
of B is transverse, and not longitudinal.
But the principle is exactly the same; even if
B is moving transversely will the Lorentz transform
predict that C will measure the same frequency as is
emitted from A.
The Lorentz transform does NOT predict the causality
violation you claim it does.
But since you obviously are completely ignorant
of what aberration is, an thus don't understand
that it is the very reason why the two Doppler
shift cancels, you will probably repeat your
mindless claim.

OK, since you insist. However, I do reserve the right to make my life
similar that is for me to set the velocity of x as observed by x'
parallel to both x and x' axes. The magnitude of the velocity is
positive going from left to right. I am also defining this angle as 0
when your angle = pi / 2. Also defining clockwise phi as positive, we
have
phi' = - cos^-1(v / c)

In the case of Mr. Thim's experiment, we have
** f_B = f_A / sqrt(1 - B^2)
** f_C = f_B / sqrt(1 - B^2)
Thus,
f_C = f_A / (1 - B^2)

Thus, the Lorentz transform obeys the principle of Relativity (from
Galileo) but violate the causality. This is the Twin's paradox. In
order to resolve this paradox, we must abandon the principle of
Relativity. That means abandoning the Lorentz transform as well.

Your cancellation method violates the very mathematics of the Lorentz
transform. You are totally lost.
Because Mr. Thim's apparatus cannot possibly observe the transverse
Doppler effect, but Ives and Stilwell's can (and did!).
As Paul Anderson pointed out, no measurement is made in the moving
frame, and the source and receiver are at rest relative to each other.
with such a setup it is not possible to observe transverse Doppler.
Moreover, the apparatus has been interpreted naively, as if the signal
propagates in a direct line from transmitting antenna to the receiving
antenna(s). This is not true, and the apparatus is more like a poorly
coupled RF cavity -- there will be a standing wave present throughout
the chamber, with many different modes excited (no competent RF engineer
would design such a thing). This wave necessarily has the frequency of
the source (in the lab frame), and is coupled by the rotating antennas
from region to region within the chamber, but all of those couplings
preserve the frequency of the standing wave (in the lab frame).
Modern technology cannot overcome a poorly designed experiment. <shrug>
And many old experimenters did remarkable things with the technology at
hand!
Tom Roberts
Hmmm. I guess I now qualify as a "retired engineer" too. But then, I
retired from telecom engineering to take a job in physics....
Yes, SR is limited in its applicability to local measurements. Still,
the majority of measurements we make are local, and on earth the
approximation involved in using SR is generally negligible for all lab
experiments not involving gravitation.
> It is based on c=const and inertial movement and that's all.
There's a lot more to SR than that. The essence is that the underlying
manifold must be flat. That is a HUGE requirement, and is one not
realized in the real world (except approximately).

That's a very basic misconception. The "universe" isn't "shrinking" at
all, it is your MEASUREMENTS that are affected RELATIVE to the
measurements of an earthbound (or Sirius-bound) observer.

I do admire you that in your elderly age you still possess a sharp mind
despite having lack of integrity. Yes, I have to swallow hard on the
fact that the initial transmit and the final receive are at rest with
each other. In doing so, there should be no Doppler shift.
However, the very mathematics of the Lorentz transform does indicate a
shift twice in the mathematics. To me, this is a clear violation of
the principles of Relativity established since Galileo. Again to me,
this indicates the principle of Relativity has to be appealed just as
the Lorentz transform tries to correct the short comings of the
Galilean transform. Since the principle of Relativity cannot exist
without either the Lorentz transform or the Galilean transform, both
for the logical point of view have to be declared wrong.

You don't have the details of Mr. Thim's setup. You cannot accuse
him of neglecting the most basic methodologies employed by a good RF
engineer.
> Modern technology cannot overcome a poorly designed experiment. <shrug>
The inappropriateness of the experiment is again very subjective. The
analogy is that beauty, evilness, emptiness, etc. are all in the eyes
of the beholders. <shrug>

This cannot be true in general. However, case by case I have no
argument. How much do you know about the exact details of
Ives-Stilwell setup?

Dirk Vdm
Almost right.
The correct answer is phi' = arccos(-v/c) (or phi' = cos^-1(-v/c))
I will assume this is what you meant.
\
\ phi'
----\-----------------------------------> x'
So we can conclude that if v and p are transverse S,
they are NOT transverse in S', because the angle between
v and p is arccos(-v/c) in S'.
Conversely we can conclude that if v and p are transverse in S',
they are NOT transverse in S, because the angle between
v and p is arccos(v/c) in S.
We can sum it up thus:
If phi = pi/2, then phi' = arccos(-v/c)
if phi' = pi/2, then phi = arccos(v/c)
The general equation valid for any angle is:
cos(phi') = (cos(phi) - v/c)/(1 - (v/c)*cos(phi))
or:
cos(phi) = (cos(phi') + v/c)/(1 + (v/c)*cos(phi'))
This is aberration.
Now, if the source is stationary in S, and the observer
is stationary in S' we can conclude:
If the velocity of the observer is transverse to the wave vector
in the source frame S, then phi = pi/2, and the observed Doppler shift
will be:
f' = f*(1 - (v/c)*cos(phi))/sqrt(1 - v^2/c^2) = f/sqrt(1 - v^2/c^2)
This is a blue shift
If the velocity of the source is transverse to the wave vector
in the observer frame, then phi' = pi/2 and cos(phi) = v/c,
and the observed Doppler shift will be:
f' = f*(1 - (v/c)*cos(phi))/sqrt(1 - v^2/c^2)
f' = f*(1 - (v/c)^2)/sqrt(1 - v^2/c^2)
f' = f*sqrt(1 - v^2/c^2)
This is a red shift.
Summed up:
----------------------------------------------------------------
# If the velocity of the observer is transverse to the wave vector
# in the source frame, the observed Doppler shift will be:
# f' = f/sqrt(1 - v^2/c^2)
#
# If the velocity of the source is transverse to the wave vector
# in the observer frame, the observed Doppler shift will be:
# f' = f*sqrt(1 - v^2/c^2)
----------------------------------------------------------------
Since this follows from the very mathematics of
the Lorentz transform which you claim to understand,
I will assume you know this is correct.
In the case you don't agree, I challenge you to show that
the above is NOT what the Lorentz transform predicts.
General talk about symmetry won't do.
You will have to do the math.
So you confirm your claim:
"Because the Lorentz transform is symmetrical, it predicts
that C must must see the signal from B Doppler shifted by
the same amount as B sees the signal from A Doppler shifted
with."
This claim is falsified below:
>> The scenario bellow satisfies the above description:
>>
>> A B -> v C
>>
>> If f is the frequency of the signal emitted from A,
>> B will according to the Lorentz transform measure
>> the frequency f' = f*sqrt((c-v)/(c+v)) and thus
>> transmit the same frequency f'.
>> C will according to the Lorentz transform measure
>> the frequency f" = f'*sqrt((c+v)/(c-v)) = f
>>
>> Thus the Lorentz transform predicts that C measures
>> the same frequency as is emitted from A.
>> And that is also what a real experiment would show,

> Yes, this is true. However, this is not transverse Doppler effect.
But nevertheless it falsifies your claim:
"Because the Lorentz transform is symmetrical, it predicts
that C must must see the signal from B Doppler shifted by
the same amount as B sees the signal from A Doppler shifted
with."

No.
In the case of Mr. Thim's experiment, we have:
v
^
|
A ->p B ->p C
Here the velocity of B is transverse to the wave vector
(or momentum) of the radiation in the stationary frame.
Case #1:
A is the source, B is the observer.
The stationary frame is the source frame.
The velocity of the observer is transverse to the wave vector
in the source frame, and the observed Doppler shift is thus:
f' = f/sqrt(1 - v^2/c^2)
Case #2:
B is the source, C is the observer.
The stationary frame is the observer frame.
The velocity of the source is transverse to the wave vector
in the observer frame, and the observed Doppler shift is thus:
f' = f*sqrt(1 - v^2/c^2)
The Lorentz transform predicts that the two Doppler shifts
will cancel each other, and C will detect the same frequency
as is emitted by A.

you were dividing by zero and Tom Roberts was observing
the earth's rotation with a sight line down between

Few would argue that your calculations were not in

quite proud to be employed by Lucent, although Dork Van de merde

I will give you a tip, Sue.
All the postings are archived on Google.
Bluffing about the content of a year old discussion
isn't very smart.
But thanks for reminding me of the fact that you
never answered the challenge.
No surprise, you never do.
Since you repeat that my expression:
<<N times per Earth rotation.>>
reduces to division by zero, I suppose you still
are unaware of the fact that the Earth is rotating.
Is it very smart to remind us of the fact?

Nobody disputes one rotation.
What you've failed to prove is delta_T <> 0, you assumed it.
A will measure the rotational frequency to be f_g = N/T
while B will measure it to be f_s = N/T, OBVIOUSLY.
||
|| So the ground clock will measure the axle to rotate

No it won't. The oscillators in question are the identical balance
wheels of the clocks.
They have identical frequencies and cannot show different times,
tautologically. If you deny it, that is against the supposition the
balance wheels are identical.
|
|| frequency * duration = number_of_rotations
|| f_g*T = N
|| f_s*(T + delta_T) = N -- wrong.
f_s*T = N
N = T/f_s

f' = (f - v * p / h) / sqrt(1 - v^2 / c^2)
In transverse Doppler case, we always have
v * p = 0
So, we always have

In this scenario, we have
** f_B = f_A (1 - B) / sqrt(1 - B^2)
** f_C = f_B (1 + B) / sqrt(1 - B^2)
f_C = f_A (1 - B) (1 + B) / (1 - B^2) = f_A
You just don't understand how to apply the Lorentz transform.

Wrong. In SR, there is no distinction between who is dong the moving.
So, your Case #2 should be the same as Case #1. The correct math is
also
f' = f / sqrt(1 - B^2)

However, if the movement is linear, we have a different story.
A --->
---> B
---> C
A sends out a photon to B which is traveling at speed = v
perpendicular. A few moments later, B sends out another photon to C.
A and C are stationary to each other.
B will observer a transverse Doppler effect from A by the amount
f_B = f_A / sqrt(1 - v^2 / v^2)
However, the speed v will slow down to v' and changes its direction
to absorb the momentum of the photon received from A.
When B sends out another photon, C will also observe a transverse
Doppler effect of
f_C = (f_B' + v' * p_B' / h) / sqrt(1 - v'^2 / c^2)
Where
** p_B' = Momentum vector of the 2nd photon in which it should be
almost 90 degrees with vector v'
Afterwards, B is going to slow further to v" and changes its course
slightly.
v is velocity in the x-direction only.
There is no mathematical reason for there to be any transverse
shift.
u = v.cos(phi)
w = c.cos(phi)
gamma = 1/sqrt(1- u^2/w^2) = <undefined>
Androcles
That figures.
But I suggest we keep my definition because it is the angle between
the velocity and the wave vector. This is the angle commonly used,
and I see no reason to adopt an unconventional definition.
And the conventional positive direction is counter-clockwise.
I started by defining phi' and I never changed that definition.
So: phi' = pi/2 - your_phi'
And then we agree.
phi' = pi/2 - (-arcsin(v/c)) = arccos(-v/c)
|y'
\ |
ct\ |
\|
---|---|-----------> x'
-vt
No more stupid quarrel over this please.

>
> phi' = pi / 2 - cos^-1(v / c)
>
> In your definition assuming counter-clockwise, it should be
>
> phi' = pi / 2 + cos^-1(v / c)
My definition is the conventional one:
phi' is the angle with the x' axis,
positive direction is counter-clockwise.
Then phi' = arccos(-v/c)
We agree about what the actual angle is.
----------------------------------------
So I repeat what you snipped:
| So we can conclude that if v and p are transverse in S,
| they are NOT transverse in S', because the angle between
| v and p is arccos(-v/c) in S'.
| Conversely we can conclude that if v and p are transverse in S',
| they are NOT transverse in S, because the angle between
| v and p is arccos(v/c) in S.
If you don't agree to this, you contradict what you
calculated right above!
So you agree!
Read the following again, please, having the definition
of phi and phi' in mind:
(unsnip)
The general equation valid for any angle is:
cos(phi') = (cos(phi) - v/c)/(1 - (v/c)*cos(phi))
or:
cos(phi) = (cos(phi') + v/c)/(1 + (v/c)*cos(phi'))
This is aberration.

No, this won't do.
I made no mistake, and I used the conventional definition
of the angle.
If there is anything in the above you think is wrong,
please point it out exactly, chapter and verse.
If you can't do that, it is because it is correct.

And neither will calling it gibberish.
The challenge stands.
No point in going on before this is settled.

Yes you did. v is dx/dt, u =dy/dt, w = dz/dt.
u = v.cos(phi) = v.0
Your stupid gamma gibberish = 1/sqrt(1 - u^2/c^2) = 1, moron.

This experiment is a perfect example of how relativity is about to be exposed
as a complete fraud by modern instruments that can actually detect the very
small changes in light speed that occur around us continually.
The only reason Einsteinian relativity has survived for 100 years is because
until now, the means were not available to test it directly. They now are.

Did you try to say something?
In that case you didn't succeed.
Try again, and express yourself in an intelligible manner, please.
The challenge is still:
I challenge you to point out an inconsistency in the above.

Henri, you are babbling again.
Neither did you read the paper, nor did you read what I wrote below.
You don't know what you are talking about.
I suspect this is beyond your abilities anyway.

This isn't true, of course, but it IS true that modern technology
has made it possible to test SR with higher precision.
The Ives-Stilwell experiment (1938) which verified the transverse
Doppler shift predicted by SR, is repeated with modern equipment:
http://www.mpi-hd.mpg.de/ato/rel/
http://tinyurl.com/ftmjq
http://tinyurl.com/zbczk
So indeed, now it is possible to test the SR Doppler prediction
with unprecedented precision.
Which is done.
SR passed the test and is better confirmed than ever.
The technology used in this experiment:
http://ieeexplore.ieee.org/iel5/7883/21718/01007152.pdf
isn't particularly new, it could have been made in the 1960ies.
But anybody with a reasonable knowledge of mathematics, physics
and microwave technology can see that this experiment tests
nothing but causality.
Causality survived. :-)
BTW, Henri:
Did you know that both Ives and Stilwell were anti-relativists?
They expected to falsify SR with their experiment.
But they were honest scientists, and didn't "doctor" their data
to get the result they wanted.
They reported the truth - their experiment confirmed SR.
Paul
As John Kennaugh once pinted out, the so called 'SR transverse doppler shift'
is just what the BaTh predicts.

Excellent! It proves the BaTh.

I suppose they were aetherists. ...just as bad...

No, Paul, they supported the BaTh.
You are wrong again...

Why do you think that lightspeed plays a role in this experiment?

Paul, obviously you should read their paper again! They expected to prove
not only the reality of time dilation but even its value, and they succeeded
(although it is debatable if they really achieved the required precision).
Harald
Quite.
If John Kennaugh said so, it must be right even if it is wrong.
Right? :-)

It tests nothing, but proves the BaTh.

Paul,
I owe you an apolgy.
That is not to say your argument is wright or wrong.
...but I am wrong to to question your creditentals as
a dedicated educator.

It was correct.
The transverse doppler shift of the BaTh is exactly what SR claims as its own
unique discovery.

The BaTh doesn't need any more proof.

Paul, how can SR be correct? You agree that nothing happens to rods or clocks
because of a velocity change yet you claim that something DOES happen to GPS
clocks, as observed by the original observer in the original frame using the
original time reference?
Tell us what really happens? Do rods and clocks physically change or not?
I don't know what you are talking about.
If you ever questioned my credentials, you didn't
get that message above the noise level of your posting.
But I know what you are NOT talking about.
My challenge to you.
The challenge is still:
Nothing happens to your clock and your rod. Your = clock and rod is at
you not moving.
Others, moving, only measure your clock delayed and your rod to be
shorter and vice versa.
That is not in confict with logic.
As I also said in this thread: according to my clock I travelled to
Sirius with 2x0.866c.
That is equal to the 1st part of the Twin paradox. Otherwise he would
not come back aged less.
You need not to accept SR. What I feel is, that as long as SR and GR
can predict/explain what is going on, it is a good tool, state of the
art. Tomorrow there could be an enhanced theory.
Galilei transformation is not valid near c. If c would have another,
higher value, all the formulas would still be valid near the other
value. So you can't get out.
Only in our thoughts we can imagine infinite speed, making us all the
troubles with Einstein.
Rudi
Henri, the issue is this paper:
http://ieeexplore.ieee.org/iel5/7883/21718/01007152.pdf
You wrote about it:
| This experiment is a perfect example of how relativity is about to be exposed
| as a complete fraud by modern instruments that can actually detect the very
| small changes in light speed that occur around us continually.
But since you have made no attempt to defend your statement, and have
made no attempt to refute my critique of the paper, I will assume
that you have accepted that the experiment does not test what was
supposed to test.
If you don't agree, read the paper, read my critique,
and point out exactly where I am wrong.
General babble is of no interest.

No, of course not, we all see trains move by peristalsis.
