The rays of light will
not meet at the origins of both frames of reference. So from A, an
observer will only observe the bell in A to ring, from B an observer
will only observe the bell in B to ring.
With my equations, the bell in A will ring first, then the bell in
B. You will hear both bells in both frames of reference.
Now, YBM, explain the same events using the Lorentz equations.
I did here :http://groups.google.com/group/sci.physics.relativity/msg/a39fe2523de...
There is no such absurdities in SR : for SR, the bell
rings in both frames... It just happens that in frame
B they were emitted at coordinates
(-a/sqrt(1-v^2/c^2),0,0) at time va/(c^2*sqrt(1-v^2/c^2))
for the "left" light ray, and :
(a/sqrt(1-v^2/c^2),0,0) at time -va/(c^2*sqrt(1-v^2/c^2))
Uh huh.
Is there something you don't understand above ?
But if you put a bell at the origin of each frame of
reference, what will happen?

So it is quite certain that you didn't read.
No, I read it, YBM. So explain what happens if there are two bells,
one at the origin of each frame of reference.
Look carefully at the coordinates of events I've provided
above. Then figure out yourself :
- at what time in B does both light rays have been emitted ?
are they the same ?
Because of relativity of simultaneioty that the Lorentz equation
require, the beams of light are not emitted at the same time in B.
right.

Therefore, according to you only the bell at the origin of A will ring
as observed by the observer in A.
- are the positions of the points of emission in frame B symetric
with respect to the origin of B ?
The points of emission are equal distances from the origin of B.
right.

- given that velocities of the light rays are c and -c in B
are they going to meet at the origin of B ?
I say they will, but the Lorentz equations say they will not.
At least you should notice that the Lorentz equations are
perfectly coherent.

If you
have a bell at the origin of A and a bell at the origin of B, only one
of the bells will ring.
You mean according to LT, right ?

So, now you "theory" says : both bells will ring, right ?
(even if this not what your formulas implies).

This is sooooo utterly absurd that I suggest you to take
a rest and think a bit about it.- Hide quoted text -

Well, I have thought about it. �The Lorentz equations say both bells
will ring,

DEFINITELY NOT !

This is really amazing ! So far :
- you lied about what Galilean Transformations say
- you lied about what your formulas say
- you lied about what LTs say

but only if you consider the problem from both frames of
reference, the same way I did with the Galilean transformation
equations, treating each frame in turn as a preferred frame of
reference.

there is no preferred frame of reference in GT.

Both bells will ring by anyone's equations. �But the objections you
make to my interpretation of the Galilean transformation equations can
also be applied to the Lorentz equations because under their current
interpretation, an observer in one frame of reference cannot see both
bells ring without a consideration from the other frame of reference.

Wrong, silly, stupid, meaningless, ill, all of that is so few words !- Hide quoted text -

I forgot something about the Lorentz equations. OK, they show that
only the bell at the origin of A would ring. The ether theory of the
Galilean transformation equations shows that A would be a preferred
frame of reference, regardless of what you believe about it. My
question is, why don't you run the experiment?
Why go around in doubt? I say both bells would ring, you say only
the one in A would ring. So run the experiment and find out.
