Naked female twins, interesting twist.

Very nice. Two suggestions:

1. Put up the equations for the two cases just below the animation,
like the hyperphysics page.

2. There seems to be a slight problem with the graphics animation,
while the clocks show exactly the same results from both A and B
perspectives, the rate of acceleration at takeoff seems different.

That would be a lot of equations cluttering the whole thing up.

2. There seems to be a slight problem with the graphics animation,

perspectives, the rate of acceleration at takeoff seems different.


There is no problem, it is as it should be.
Just about everything seems different from A's and B's perspective.
That includes the reading of the clocks _during_ the journey.
Look at the rate curves. The reading of "the other clock" is the
integral of its rate.

But thanks for running my program.

I forgot something...Paul would you know what is incorrect below:

#1. A light signal and a ball moving at 2/3c with respect to a
platform also moving at 2/3c simultaneoulsy go from Point_A to
Point_B.

#2. For a Rest Frame Observer, light speed remains the same but the
ball's speed is modified using w = u+v/(1+uv/c^2).

T_restframe = T_invariant/gamma does not seem correct to be used for
both the light and the ball moving at w (instead of "u") even though
AtoB distance has contracted the same for both: L_restframe =
L_invariant/gamma?


Where is the error above?

Slight mistake T_restframe = gamma T_invariant

..... because I believe it takes the moving platform longer to achieve
the same invariant distance travel.

But the same problem still exists?
