Hi Jim, long time no see.

A great enrager of Srians are mild questions about the energy (kinetic)
which vanishes
or miraculously appears depending on which "frame" they chose to place the
particle(s) in.

The same is true in Newtonian physics, the kinetic
energy of an object is zero in its rest frame
and the value diffes from frame to frame regardless
of what theory you use.

Nonsense, George. There is only one frame of reference in Newtonian
physics, a universal isometric Euclidean-Galilean-Cartesian-Newtonian
frame of reference whose origin can change but whose metric properties
remain constant unlike second order velocitiy dependent anisometric
properties of reference frames in SR. And that one universal frame of
reference is the reference frame against which all dynamic properties
such as momentum and energy are judged whether at rest or in motion.

...........mostly in the form of the pathetic wail "You just don't
UNDERSTAND SR!!!!!!!!!!

Well that is certainly indisputable.

Especially bring it into arguement regarding "velocities don't add"; I
love it when they totally disregard conservation of energy.

A fine example, energy is of course conserved in SR.

George
