They realy do slow

We can't say they 'really slow' but we can say that they appear to run
slow AND that when they return from a round trip they show less elapsed
time.

Sue, on the other hand, claims that the traveling twin's clock
continues to run at the exact same rate as the stay-at-home,
accumulating the same number of ticks on that round trip.

Yes


She goes so far as to propose an extension cord to drive a synchronous
clock. Since the cord's length doesn't change (just the lead dress or
configuration), the signal on the cord doesn't change.

Yes


She DOES ignore the fact that the cord must be 'pre-charged' with
signal before the launch. She does ignore the fact that many cycles
remain on the cord at the end of the trip.

Yes.
Are you going to dispose of all your power mains
synchronised devices for the reasons you stated?

If so, I may give up drinking water because the pipes
have been 'pre-charged' and water will remain
in the pipes after I draw a glass from the tap. :o)

You would take that water into account if you had to pay for any you left
in the pipes. Who pays for liquids left in the pipeline when the line is
disconnected and the liquid wasted?

Hint: the water company's cost are based on moving all the water, not just
the water you drink.
They charge you for MOVING the water AND base the charge on their costs,
pro rated on the basis of the water you used.

They KNOW better than to just charge you for the water you drink. They
charge for delivering it to you.




She thinks that the AC clock would keep the same rate as an atomic
clock or a quartz clock, or even a light clock INSIDE the ship, but a
light clock (and only a light clock) exposed to the 'dielectric' of
space WOULD be slowed as L-E equation shows.

Absent local gravitational influences on the atomic clock yes.
The light in an AC power cord does not weigh much so it
doesn't care whether planets are nearby.


She also thinks that any parameter that is plotted on the i axis is
unreal and unphysical, specifically reactive power and time in
space-time equations.

Many capacitor banks that correct for apparent power can
be removed if I am wrong about this.

NO! You can be wrong and the capacitor banks still be required.

If you were right it would imply capacitor banks are needed IS correct
logic.
If capacitor banks are NOT needed would imply you were wrong IS correct
logic.

But you being wrong has no effect on capacitor banks being needed.
Study your logic again.

http://en.wikipedia.org/wiki/Power_factor_correction

We have discussed this before. I demonstrated that instantanious power
computed by using the voltage at each instant and the current at each
instant and multiplying them together, then integrating yields the correct
answer.
I also told you WHY electricians use RMS meters and multipy the 'so
called' apparent power by the power factor.

It amounts to economics. Why carry an oscilliscope with capability to
integrate the actual power over the entire ac cycle when a cheap RMS meter
and the power factor give the same answer?

That does NOT mean that the 'simplified explanation' given to the
electrican, that the 'volt-amp' power is 'imaginary' is a correct
explanation.

It is NOT a correct explanation. It should never be used because it leads
people[even somewhat educated people, such as you], far astray.

And she accuses others of believing in myths while she retains all
those mythconceptions, none of which are supported by any of the
'credible sources' she cites.

Mathematics does not look to the credibliity of sources.

Right. And 'imaginary power in reactive circuits' ISN'T imaginary.

The waiter did NOT make a dollar vanish. PERIOD!
No appeal to authority can change that.

Right. So admit that you were wrong and get on with life.



Twins can't disagree on the number of orbits
Jupiter's moon makes. PERIOD!
No appeal to authority can change that.

Right. But they can disagree upon how long the orbits took by their clocks.


If you want to argue THEE inertial mechanism
reaches inside ships a lays its thumb on
the balance wheel of a clock, according
to the motion of other clocks, that is
an issue that authoritative appeal might
illuminate.

I don't argue about any 'THEE' mechanism.
I just cite Tau = 1/2 t v^2/c^2 (and other equations developed by Lorentz,
Einstein et al, and tested by many experiments since).

Neither Newton nor Einstein used a theory
of inertia but is clear from GR
that Einstein rejected the absoulte
space that you and Jeckly need to
cause a *real* clock to slow with motion.

The clocks on the GPS satellites have rates that are consistent with the
predictions of Einstein.
Those clocks are real enough for me.
