These indoctrinated idiots have since then deified another indoctrinated idiot, Einstein the nitwit, the plagiarist, and the liar, to be the god of relativity.  Since then, that stupid god of relativity, Einstein the nitwit, the plagiarist, and the liar, has whispered into the ears of these indoctrinated idiots self-contradictory laws of physics.  <shrug>

There are an infinite numbers of antitheses to SR that have always supported any experiments that have thrown at them.  It is utterly ludicrous for someone to claim one particular valid thesis out of them just because their stupid god, Einstein the nitwit, the plagiarist, and the liar, had whispered into their years.  <shrug>

Indeed, Koobee Wublee sees no reason to admire these indoctrinated fools and idiots that their stupid god, Einstein the nitwit, the plagiarist, and the liar, has been whispering into their ears.  <shrug>

You will not get anywhere by repeating the same words. It's obvious
to the reader that you have nothing to say, you simply feel compelled
to cut and paste the magic phrase "Einstein the nitwit, the plagiarist,
and the liar".

I'm not sure what planet you live on but on my planet saying things
don't make them true.

Saying things is exactly what make them true.

What alternative do you have? Except saying it's
not true?

Well, if you would be willing to discuss some equations, what I would point out is that the velocity transformation for the Lorentz equations is

                     u' = (u-v)/(1-uv/c^2)

                     u=dx/dt
                     u'=dx'/dt'

Now if we take the Galilean transformation equations and use them in the mathematically correct manner, we get the exact same equation for the same two measurements of time, the time of a clock in S and the time of a clock in S'.  

                     x'=x-vt
                     y'=y
                     z'=z
                     t'=t

t is the time of a clock in S.  Notice the two little horizontal lines between t' and t.  They are called an equal sign.  If t is the time of a clock in S, then t' is also the time of a clock in S.  These equations do not say anything about a slower clock in S'.  So since scientists have told us that the transitions of a cesium atom slow down in S', we have to use another set of Galilean transformation equations to show this.  

                     x' = x - (v2)(t2)'
                     y' = y
                     z' = z
                     (t2)'= (t2)

You will notice that the coordinates for this set of Galilean transformation equations are S(x,y,z,(t2)) and S'(x',y',z',(t2)').  (t2)' is the time of the slower clock in S'.  Once again, notice the two little horizontal lines between (t2)' and (t2) which are called an equal sign.  If (t2)' is the time of the slower clock in S', then (t2) is also the time of the slower clock in S'.  t and t' are in the other set of Galilean transformation equations.  Now if the speed of light is measured to be c=300,000 km/sec according to the time of the clock in S, then x=ct, or light travels a distance of x in a time of t.  If this speed of light is measured to be c=300,000 km/sec in S' according to the time of the slower clock in S', then x'=c(t2)'. 

                       x'=x-vt
                       c(t2)' = ct -vt
                       (t2)' = (t-vt/c) = (t-vx/c^2) if x=ct
                       

So now we transform velocities using the times of the clock in S and the clock in S'.  

                      u=dx/dt

                      u' = dx'/d(t2)'

                      x' = x - vt
                      dx' = dx - vdt

                     (t2)' = (t - vx/c^2)
                     d(t2)' = (dt - v dx/c^2)
                
                     dx'/d(t2)' = (dx-vdt)/(dt-v dx /c^2)
                              = dt(dx/dt-v)/dt(1 - v dx/dt /c^2)
                              = (dx/dt-v)/(1 - v dx/dt /c^2)
                              = (u-v)/(1-uv/c^2)

OK, I will repeat the results of this for the scientists once again.  For the Lorentz equations where t is the time of a clock in S and t' is the time of a clock in S',

                      dx'/dt'= (u-v)/(1 - uv/c^2)

For the Galilean transformation equations where t is the time of a clock in S and (t2)' is the time of a clock in S', 

                      dx'/d(t2)' = (u-v)/(1 - uv/c^2)

Once again it seems that scientists do not want to discuss equations.

Say, you bring a clock from x=0 to x = D at speed v. What value will *it* indicate on arrival at D ? Does you eqs give the correct value?

Your aproach/eqs seem to be overkill to the unique use of the LT's

Yes, the Galilean transformation equations give the correct value.  It does not matter what the value is.  Suppose that the clock slows down as Einstein predicted in Special Relativity.  Then the time of the clock is shown by a set of Galilean transformation equations

                         x'= x - (v2)(t2)'
                         y'=y
                         z'=z
                         (t2)' = (t2)
(t2)' is the time of the clock that moved from x=0 to x=D at speed v.  In the above set of Galilean transformation equations, the speed is shown as (v2) because a slower clock results in a slower speed between frame of reference S and frame of reference S'.  Speed v appears in the original set of Galilean transformation equations 

                       x'=x-vt
                       t'=t

where t is time as shown by a clock in S.  t' is also time as shown by a clock in S because the Galilean transformation equations can only show one measurement of time in one set of equations.

Scientists seem to think so.  The difference between the Lorentz equations and the Galilean transformation equations is that the Lorentz equations claim that if a clock in S' is slower than a clock in S, the times of both clocks still result in a speed of v between the frames of reference of the clocks.  Scientists will not discuss this at all.  But suppose Hafele and Keating had used the time of their clock on an airplane to calculate the speed of the airplane.  Would they get the same speed for the airplane if the clock on the airplane was slower than a clock on the ground?  The Galilean transformation equations are the correct equations, as experiment shows.  A slower clock results in a faster speed for the airplane.  A faster clock results in a slower speed for the airplane.  Experiment plainly shows this to be true.

Yes, that is true.  That is the reason why scientists ran the experiments in the first place.  As soon as they confirmed that a clock in S' was slower than a clock in S, they accepted it as proof that SR and the Lorentz equations were true.  The Galilean transformation equations had long since been discarded.  The never once considered using the Galilean transformation equations multiple times for different clock rates with different variables for time instead of just once with Newton's absolute time interpretation.  Nobody did for more than a hundred years until I did it.

Well, perhaps the Galilean transformation equations seem too difficult for scientists, but that does not change the fact that they are the correct equations.  The Lorentz equations give correct answers to some problems because of the velocity transformations.  If u=dx/dt and u'=dx'/dt' in the Lorentz equations, then
  
                        u'=(u-v)/(1-uv/c^2)

If u=dx/dt and u'=dx'/d(t2)' as I have shown in the Galilean transformation equaions, then 

                       u'=(u-v)/(1-uv/c^2)

The only difference between the two sets of equations is that x' in the Galilean transformation equations is not the same distance as x' in the Lorentz equations, and t' in the Lorentz equations is not the same amount of time as (t2)' in the Galilean transformation equations.  But u and v are the same in both sets of equations, so the equations are really identical in result.  If scientists are too lazy to realize that they are using a horse, that is, something that seems easy to them but is not exactly done with correct mathematics, then let scientists do what they do.  Their best efforts to destroy the universe will all fail.

Prove it.

Irrelevant. This is not about E's SR, but *your* model, your eqs. 

<mumbojumbo snipped>

So, no answer to my question? Here it is again: Say, you bring a 
clock from x=0 to x = D at speed v. What value will *it* indicate 
on arrival at D ?

Express your answer as a function T_val = F(D,v)

Well, they are useful since they directly predict the value(s) on clocks (and energies, frequencies etc...)

But the LT's dont predict that; SR doesnt say that.

Not sure what you are geting to with that. Yes, "v" is defined via time, or clocks. "v = dx/dt". In practice, "v" also has operational procedures/definition.

> But suppose Hafele and Keating had used the time of their 
> clock on an airplane to calculate the speed of the airplane. 

How would they do that? They would need a distance. Their distance is always zero wrt themselves. Its <>0 wrt the ground. Its <>0 wrt the sun. "speed" is defined wrt a given frame; its defined via "x and t" of that frame, not of a mixture of frames. 

> Would they get the same speed for the airplane if the clock on 
> the airplane was slower than a clock on the ground?  

The plane observers measure the speed of the "traveling ground". Ground observers measure the speed of the plane. Experimentally, these give the same value and is what SR predicts too. So plane observers just say "our plane has speed v" when technically it should be understood as "the ground has speed v".

It was done many times throughout history. And note that your derivations also use the constancy of speed of light postulate. Basically, you are combining two models together, using twice as many equations, all to get no answers (you havent answered my question, remember?). Your approach is not very useful it seems.

The velo.trans come from the LT's which come from the relativity principle. Its not something extra added to SR. In your approach, you add so many extra "things" to get no answers; hardly useful.

It was answered in the equations I posted.  The Galilean transformation equations show reality.  If you have a clock with some other rate of time, you use a different set of Galilean transformation equations with different variables for velocity and time.  That is the correct way to do it.  If a clock in S shows light traveling at c, and a slower clock in S' shows light traveling at c, Then x=ct and x'=c(t2)'.  What I showed with the velocity transforms was that

           dx'/dt' in the Lorentz equations = dx'/d(t2)' in the Galilean transformation equations. 

But since you say that is wrong, go ahead and prove it.

Dont lie; I didnt say it was wrong. I said that "In your approach, you add so many extra "things" to get no answers; hardly useful."

E.g. If you bring a clock from here to over there, at a speed v, a distance away of D, what value will the moved clock indicate on arrival over there?

They simply use, obey to the convention, nothing more.

They don't care about the relativistic improvisations at all!
The situation is drastically opposite:
they just want keep their actual status.

That position is called as a conformism...
nothing more, nothing new under the sun.

The SR model works good under the strict local conditions...
so, you are naive only, because you don't know even about the your naive theory.
That position is a naked, blind idiot state!

You are just smart like the idiotic inquisitors, which tried
to destroy the Galileo's moons... insitu.

The relativity improvisation is widely known as
an naive approx. of the general, ie. the strict, strong, rationale, real classical theories.

Ah, Alice in Wonderland, wishful thinking. It goes something like this:
"I failed at becoming a genius physicist. So I'm going to declare all
physicists something that I can present at a level lower than myself.
How about "stupid"? Well, this one has already been taken by Maciej,
so let me try another one: "they obey to the convention, nothing more".
Prefect.

No, it's called your ignorance of the actual issues involved.

Indeed...
the QM's 'logics' promoters usually use the Alice
and the stupid, but the very voiced, Bells. :)

It's very impressive composition... for naked babes. :)

The geniuses are possible in your mainstream improvised pseudoscience only.
Any other never exist at all.

Said a bull to the Aristotle... :)

You OBVIOUSLY do not know any physicists. We check our work in as many ways as 
possible, and if SR did not provide accurate answers it would have been 
abandoned long ago.

	And in some situations is HAS been abandoned -- those which are
	outside its domain of applicability.

Again, you don't have a clue about how physicists ACTUALLY behave. Accurate 
answers are more important than "status", because one could not achieve any 
"status" at all without accurate answers.

As when those phenomenon can be explained by means of something else apart 
from SR.

This is not accurate, to the number of decimals necessary. The most of the 
achievable status are achieved by answers shown to be interpreted wrong 
later on.

The SR nothing explains,
therefore everything is explained beyond this model;
typical examples:
- the twins paradox, which is resolved clasically... but still wrong
- the Bells rocket paradox
- a general time paradox - in a rotational motion, ect.
- the stellar aberration, which depends on motion of the observer only,
 never any relative speeds!
- the light speed variability
- every waves phenomena

ect. the list is inffinitely long!

The great claims needs the very great data, unfortunately.

What sort is the 'we'?

Such collective confession is a specialty of:
religion, mysticism, and of pseudoscience.

I one, alone, a single classical being,
can to destroy your the collective naive beliefs... in 5 seconds!

Abandonment of the applied convention is impossible for any conventionalist. :)

Do you can't believe in that?
Look at yourself... HAHA!

at this place I just use your string:

HAHAHAHAHAHA!

Priceless.

When this newsgroup was created, it was done so in order to divert the crank
traffic from sci.physics. But we didn't know there would be so MANY of the
deranged idiots out there. They did clog sci.physics somewhat, mostly with
the unending threads on the twin paradox, but it seems the new forum attracted
many more weirdos. For a student of human mental pathology it's very interesting.
