As seen in Moe's frame where time t is used:
http://users.pandora.be/vdmoortel/dirk/Stuff/MoeLarryCurly.gif
<Total proper time Larry>
= Int{ 0 to T/2; 1/glout dt } + Int{ T/2 to T; 1/glin dt }
<Total proper time Curly>
= Int{ 0 to T/2; 1/gcout dt } + Int{ T/2 to T; 1/gcin dt }
where the gamma values are given by
glout = 1/sqrt[ 1 - v^2/c^2 ] Larry outbound
glin = 1/sqrt[ 1 - (-v)^2/c^2 ] Larry inbound
gcout = 1/sqrt[ 1 - (-v)^2/c^2 ] Curly outbound
gcin = 1/sqrt[ 1 - v^2/c^2 ] Curly inbound
and you see that
glout = glin = gcout = gcin
so finally
<Total proper time Larry> = <Total proper time Curly>
= 1/g * Int{ 0 to T; dt }
= 1/g * T
= <Total proper time Moe> / g
where
g = 1/sqrt[ 1 - v^2/c^2 ]

Larry and Curly have accellerated equally away from Moe's rest frame in
opposite directions, thus Dirk concludes, nay 'proves' above that from
Moe's rest frame Larry's and Curly's clocks will have ticked equally wrt
Moe upon thier symetric return to Moes frame. Moreover Moe's clock will
have ticked a greater number of times than Larry's and Curly's clocks.
Now let's suppose that Moe, Larry, and Curly were previously all at rest
in Shem's frame, which is identical to Curly's outboud frame above.
Let's also suppose that when Moe, Larry, and Curly departed from Shem's
rest frame to enter Moe's rest frame above, that another party
accellerated equally in the opposite direction to Moe, Larry, and Curly,
wrt Shem's frame in a symetric manner just as in the case above:
Thus we have an identical system as above, that is, accoding to Dirk
Moe's clock must be ticking slower than Shem's clock.
So after Larry and Curly accellerate away from Moe, in Dirks argument
above, then we have:
1) Curly's clock is ticking slower than Moe's clock, wrt Moe.
2) Moe's clock is ticking slower than Shem's clock, wrt Shem
3) Curly's clock is ticking at the same rate as Shem's clock, wrt Shem
If this last sequence is sustained for a very large interval, then the
durations of the acclerations do not enter into the outcome. For all
practical purposes Shem's and Curly's clocks remained at rest wrt each
other throught the total sequence.
Thus according to Shem, Curly's clock is ticking faster than Moe's
clock, but according to Moe Curly's clock is ticking slower than Moes'
clock, these ticking rates are reversed. Shem and Moe cannot agree upon
the relative ticking rates of these clocks. OTOH, there will only be one
objective outcome, which is independent of perceptions of it, thus
either Shem or Moe, or both, are morons for thinking that the Lorentz
transform is invariant wrt frames of reference, and that it has anything
valid to say about the ticking rates of clocks.
No amount of mathematical torture will cure this mishap, SR is
internally inconsistent. OTOH if K is always taken as the frame of the
medium, then no such contradictions arise. Time dilation can only be
logically maintained when it is a function related to some absolute
field such as the gravitational field of a planet, Sun, Galaxy, etc.
Thus the very real need for a 'general' theory of relativity to
eliminate the contradictions of SR, or IOW to undo the mistake that was
SR. It yet remains to be shown how even Einstien's version of the
'general' theory will resolve the pelucid contradiction illustrated
above.

<Total proper time Curly>

where the gamma values are given by

so finally
<Total proper time Larry> = <Total proper time Curly>

= <Total proper time Moe> / g

Splash already :-)
I have *not* proven what you say here, because what
you say is total rubbish, showing that you don't know
what you are talking about.
I have proven above that Larry's and Curly's clocks will
have ticked equally upon their symmetric return to Moe.
Moreover Moe's clock will have ticked a greater number
of times than Larry's and Curly's clocks.
Read it carefully and spot the differences with your
nonsense.
Then try again, but keep in mind that linear algebra and
analytical geometry garantee that my proof is sufficient.
We don't have to check the calculations in other frames
since the Lorentz transformation is linear.
No amount of words rooted in your pathetically malicious
self-inflicted misunderstanding will make that go away.

Hallo Richard,

But obviously you are not!

He still has to collect his own fumbles and post them. The above reply

He has provided the fucking math but better still, you've provided the

Here is the tough one for you and Dirk:
In reality motion velocity is expressed as m/m so it is a dimensionless
number.
Or is it?

Velocity can be expressed as distance per unit time. Or it can be
expressed as a fraction of the speed of light in a specified direction.
Speed as a fraction of the speed of light appears to be dimensionless,
but it isn't.
Bob Kolker
Bob raises a good point!
As he indicates, and this is very important,
"Speed as a fraction of the speed of light appears to be dimensionless,
but it isn't."
When you divide speed by C you end up with a
seemingless dimensionless number,
which is really a tangent function,
as I graphically show in the physics tutorial
which can be downloaded from my web site.
And the tutorial goes on top show that
Special Relativity is basically the law of tangents.

Tom Potter http://tompotter.us
0.8 c is velocity with unit, but the 0.8 is unitless.
Special Relativity is NOT basically the law of tangents.

Sam, I don't, and didn't, expect you to comprehend this fact,
as you have a serious mind lock,
and are an evangelist for the holy algorithm.
I posted this information so that the folks who don't
have locks on their minds,
can take a look at my presentation,
and decide for themselves.
Addition of tangents:
tan(X+Y) = tan(X) + tan(Y) / 1 + tan(X) * tan(Y)
Addition of velocities ( "C" set to one (1)):
velocity(X+Y) = velocity(X)+velocity(Y) / 1 + velocity(X) * velocity(Y)
Velocity != Tangent

Dirk Vdm
Addition of velocities ( "C" set to one (1)):
velocity(X+Y) = [ velocity(X)+velocity(Y)] / [ 1 + velocity(X) *
velocity(Y) ]
As you can see from this example,
and from the graphic development in the physics tutorial
that can be downloaded from my web site,
[velocity / C ] is a tangent function,
and Special Relativity is basically the law of tangents.
In other words, velocities are basically tangents,
and they add according to the law of tangents.
They don't.
If you insist on using your notation
velocity(X+Y) =
[ velocity(X)+velocity(Y)] / [ 1 + velocity(X) * velocity(Y) ]
then that is okay, provided X and Y refer to the so-called "rapidity"
and the velocity function is the *hyperbolic* tangent:
v = velocity(X) = Tanh(X) or c*Tanh(X/c) if we don't take c=1
u = velocity(Y) = Tanh(Y) or c*Tanh(Y/c) if we don't take c=1
*Only* then you can say in a mathematically correct way:
velocity(X+Y)
= Tanh(X+Y)
= [ Tanh(X) + Tanh(Y) ] / [ 1 + Tanh(X)*Tanh(Y) ]
= [ velocity(X)+velocity(Y)] / [ 1 + velocity(X) * velocity(Y) ]
So in this case the notation you used is okay, provided of course
you use the hyperbolic tangent and not the trigonometric tangent.
(see also
http://math.ucr.edu/home/baez/physics/Relativity/SR/velocity.html )
If you are not prepared to do this, you immediately get in
trouble with your notation.
Of course there *is* a connection between velocity and
the trigonometric tangent, but that has nothing to do with
addition of velocities or with relativity. That is purely
elementary calculus and ditto geometry.
Dirk Vdm
Maybe not, but Tom raises an interesting point, although unfortunately
makes a sign error as well, as
tan(a+b) = (tan(a)+tan(b)) / (1 - tan(a)*tan(b))
However, if one looks at the problem abstractedly,
v' = (v + w) / (1 + vw/c^2)
If we state that c = 1 (which can be done by an appropriate
choice of units, we get)
v' = (v + w) / (1 + vw)
which is awfully close to
tanh(a + b) = (tanh(a) + tanh(b)) / (1 + tanh(a) * tanh(b))
So a velocity could be construed as a form of hyperbolic tangent.
Whether it's useful I for one don't know; at this point it's
merely an odd sort of transformation.

It should look similar. The derivation for the lorentz transforms
gives you both rotations and boosts. Does,
x' = \gamma x - \gamma\beta ct
ct' = \gamma ct - \gamma\beta x
resemble:
x' = x cosh(A) - ct\beta sinh(A) = cosh(A)[ x - ct tanh(A)]
ct' = ct cosh(A) - x\beta sinh(A) = cosh(A)[ct - x tanh(A)]
and look similar to:
x' = x cos(B) + y sin(B)
y' = y cos(B) - x sin(B)
-----------
\beta = tanh(A)
\gamma = cosh(A)
\gamma\beta = sinh(A)
