Re: Langevin's paradox again

Let's look at the following scenario:
 - Twin A and twin B are inertial and co-located.
- Twin B accelerates at the proper acceleration 2 c/year
   away from A for 1 light year [ly] in A's rest frame.
- Twin B  coasts (no engine) for 8 light years until he is 9 ly from A.
- Twin B accelerates at 2 c/year towards A. He will reach 10 ly and
   go back to 9 ly when he stops the engine.
- Twin B coasts from 9 ly to 1 ly-
- Twin B accelerates at 2 c/y until he is co-located with A.
 Note:
While B is coasting and inertial we have two inertial twins
moving at the constant speed 0.943 c relative to each other,
and both will measure the other twin's clock to run slow by
the factor 0.333.
Yet B ages 9.18 years while A ages 22.63 y.
 B's accelerations make all the difference.
 The greatest relativistic physicist in the universe
(Richard Hachel) will probably not read this,
and if he does i won't understand it.

Yes, your post appears, and I can read it.
I will answer it.
I think you're making a mistake in the concept, and I should easily explain why.
