In discussing the Sagnac effect, both relativists and anti-relativists
make the following mistake:

http://www.mathpages.com/rr/s2-07/2-07.htm
"Quantitatively, if we let w denote the angular speed of the loop,
then the circumferential tangent speed of the end point is v = wR, and
the sum of the speeds of the wave front and the receiver at the "end"
point is c-v in the co-rotating direction and c+v in the counter-
rotating direction.....This analysis is perfectly valid in both the
classical and the relativistic contexts."

The values c-v and c+v above are "perfectly valid" only in the
relativistic context. If by "classical" the author means "Newtonian",
the analysis is by no means "perfectly valid". According to an
observer at rest, in the classical context, the speed of light is c+v
in the co-rotating direction and c-v in the counter-rotating direction
so the correct text would be:

"Quantitatively, if we let w denote the angular speed of the loop,
then the circumferential tangent speed of the end point is v = wR, and
the sum of the speeds of the wave front and the receiver at the "end"
point is c in the co-rotating direction and c in the counter-rotating
direction."

Of course, the implicit assumption above is that photons' subsequent
bumping into rotating mirrors does not change their speed
additionnally (e.g. the speed of photons in the counter-rotating
direction gets even lower than c-v), which is by no means obvious.

If one sticks to the ballistic theory and assumes that, according to
the observer at rest, the speed of the photons is c-v in the counter-
rotating and c+v in the co-rotating direction all along, the following
observation is relevant. The real path of the photons is a polygon
inscribed in the rotating circular loop. It is easy to see that the
sides of the polygon covered by c-v photons are LONGER than the sides
of the photons covered by c+v photons. This seems to be an advantage
allowing c-v photons to arrive at the end point earlier than c+v
photons. The problem is purely mathematical but its rigorous solution
seems difficult for the moment.

Rotation rate w
Tangential speed wR
Speed of light in rotating frame c
Velocity of light in non-rotating frame wR+c, wR-c
Distance travelled by light in rotating frame wRt, -wRt
Distance travelled by light in non-rotating frame ct+wRt, ct-wRt

t(c+wR) = t(c-wR)
OR equivalently,
t(c+v) = t(c-v)
The times are the same, the distances are different.


Einstein set up
x' = x-vt, the transformation from the moving frame to the
stationary frame but
Einstein OMITTED
-x' = -x+vt for the return journey.

Sagnac is isomorphic to Einstein's thought experiment, but Einstein
BLUNDERED the simple algebra at schoolboy level, right here:

Loading Image...

He claimed the return distance is x-vt with time t = (x-vt)/(c+v)
when it is in fact t = (vt-x)/(c+v).

From this BLUNDER he calculated the cuckoo malformations that
he blamed on Lorentz and called "transformations".

The rigorous solution is NOT difficult.

Lets look at what you claim wrt ballistic theory
Post by Androcles
Rotation rate w
Tangential speed wR
Speed of light in rotating frame c
Velocity of light in non-rotating frame wR+c, wR-c
Distance travelled by light in rotating frame wRt, -wRt
Distance travelled by light in non-rotating frame ct+wRt, ct-wRt
so distance is t(c+wR)t and t(c-wR) in the non rotating frame
Post by Androcles
t(c+wR) = t(c-wR)
OR equivalently,
t(c+v) = t(c-v)
How can you equate these .. they are different values ? I think you were a
bit confused in the lines above
Post by Androcles

Yes .. the times are the same in both frames in ballistic theory

In the rotating frame the distance and speeds are the same. The light
leaves the source travelling at speed c in opposite directions, it traverse
the same distance and arrives back at the detector at the same time and the
same speed travelling the same distance for a null Sagnac effect

So where is the detected Sagnac effect?

See http://www.users.on.net/~roger_onslow/Sagnac.html for a ballistic vs
relativistic animation comparison .. no sagnac effect for ballistic theory.

Michelson-Morely, OTOH, contradicts (stationary) aether and supports

You can't even spell "Morley", let alone simulate Sagnac or provide
any mathematics. You are a bullshitter, Sagnac is entirely consistent
with emission fact and isomorphic to the crank Einstein's thought
experiment (without his blunder).

In Einstein's case if you use c+v you can derive c = (c+v)/(1+v/c) from
the cuckoo malformations he blamed on Lorentz. That says you can't
use c+v.

What troll kooks like Schwartz, Poe, McCullough, Roberts, Draper, Lawrence,
Andersen, Nieminen, ewill, Olson, Tom & Jeery et. al. fail to realise is
the existence of isomorphism

http://en.wikipedia.org/wiki/Isomorphism

between Sagnac's real experiment and Einstein's hallucination experiment,
shown here:
http://www.androcles01.pwp.blueyonder.co.uk/TwoSpeedRack.gif

Einstein sends light along the rack and back again, the rack
moving at velocity v in his pipe dream.

Sagnac sends the light around the gear wheel for real.
If you analyse one you should get the same result as the other, but
you cannot use SR to derive SR, that is petitio principii, circularity.
http://en.wikipedia.org/wiki/Begging_the_question

c+v is essential to the derivation of the cuckoo malformations, the
part where Einstein screws up is:
'we establish by definition that the "time" required by
light to travel from A to B equals the "time" it requires
to travel from B to A' because I SAY SO. -- Rabbi Albert Einstein

What he is claiming is that his "definition" is true for all frames of
reference. The absurdity that the velocity of light is the same
in all frames of reference is a consequence of that claim.

Abstract--The famous Fizeau's interferometry experiment
with fowing water is commonly cited as a demonstration
of the velocity transformation in the special relativity.
In this investigation, by taking into account the
modification of the propagation velocity due to the
motion of dielectric medium and the modification of
the propagation length due to the Sagnac effect, an
entirely different interpretation of this experiment
is presented. Physically, the influence of the medium
velocity on the phase velocity is associated with an
effect of the polarization current. Both the medium
velocity and the Sagnac effect depend on earth's rotation,
while its influence on the phase difference
in Fizeau's experiment cancels out substantially.

The values c-v and c+v above are "perfectly valid" only in the
relativistic context. If by "classical" the author means "Newtonian",
the analysis is by no means "perfectly valid". According to an
observer at rest, in the classical context, the speed of light is c+v
in the co-rotating direction and c-v in the counter-rotating direction
"Quantitatively, if we let w denote the angular speed of the loop,
then the circumferential tangent speed of the end point is v = wR, and
the sum of the speeds of the wave front and the receiver at the "end"
point is c in the co-rotating direction and c in the counter-rotating
direction."

"It's also worth noting that there is no Doppler shift involved in a
Sagnac device..."

If this is experimentally confirmed, then the Sagnac effect clearly
confirms the ballistic theory and refutes relativity. The Doppler
shift, just like the gravitational redshift, obeys the formula

F = S/L

where F is the frequency measured by the receiver, S is the sum of the
speeds of the light and the receiver at the moment of reception and L
is the wavelength. According to the ballistic theory (see above), S=c
in both directions and therefore the prediction is: "no Doppler
shift". Relativity gives S=c-v in the co-rotating direction, S=c+v in
the counter-rotating direction and therefore the prediction is: "two
different Doppler shifts".

Obviously bullshit.
You'd know all about bullshit .. you spout enough of it.

As the source and detector are comoving, there would be no Doppler shift ..
you only get Doppler shift when the source and detector are relatively
moving (ie the distance that the light has to travel increases with time).
