Yes, seen that before. Give Koobee Wublee a break. Transformation of
is asking you if you can derive the energy transformation for Special
Relativity. <shrug>

By the way, it is Koobee Wublee who is asking you this. Why are you
avoiding Koobee Wublee and tried to reply to a person who did not
raise the issue? What are you scared of? Oh, the past experience
dealing with Koobee Wublee still brings back nightmares. :-)

Indeed, paul. What took you so long to realize the Doppler thing is
basically the aberration stuff? If you don?t understand the
aberration stuff is the same as the Doppler thing, how can you accuse
someone else of confusing between aberration and parallax? <shrug>

Have you not read that paper of Einstein the nitwit, the plagiarist,
and the liar? The nitwit did not offer any derivation if you have
noticed. He must have plagiarized from someone else. Don?t you
agree? <shrug>

Oh, by the way. You must have exhausted all the attempts to fudge a
convergence in time elapses for that scenario where both twins travel
with the exact same acceleration profile. Isn?t it about time to be a
man of tall statue and come out to admit the Lorentz transform is just
wrong? <shrug>
