FYI, the E=mc^2 relationship (where "m" is rest mass, and "E" is the
energy in the rest frame of that mass) also shows up as a consequence
of the equations of Newtonian theory.

Einstein happened to present his 1905 argument using the equations of
LET/SR, but the trick seems to work just about as well either way.
(if anything, the "Newtonian" calculation is marginally simpler).
