This explains why the Roberts, Andersen, Jerry use of the rotating frame to
explain Sagnac is so pathetically purile. Essentially, all they have done is
prove that a nonrotating Sagnac interfrometer does not rotate.

See what I according to HW have done:
"You have - quite brilliantly, I might add - illustrated how
a rotating observer will view a NONROTATING Sagnac interferometer."

If you are a non rotating observer and think
the interferometer is rotating, then you are
ignoring the imaginary effects.
That's bad, according to Doctor Wilson.
The apparent rotation of the interferometer is a Willusion.
What you really see is what you would have seen
if you were rotating and the interferometer were not.

That's why I have proven that the rotating interferometer
really is non rotating. And non rotating interferometers
are not rotating.
QED!

If this isn't clear to you, ask Henri Wilson
to explain it. He is the only Doctor in this forum
with a deep understanding of imaginary effects like
the non rotation of the rotation.
