Most people have never heard of
"Einstein's second-most famous
mass/energy equivalency formula"
that he outlays at the end of the
"Out of my Later Years" in terms
of the "Einstein's bridge" concept
if you've heard of that, m m' (1-c)
or what it is, Einstein's "second most
famous mass-energy equivalency formula,
that nobody's every heard of".

Most people have heard of "mc^2",
and furthermore have no idea that
it's m (c^2 + c'^4 + c''^6 ...), "the rest
of the infinitary expansion", in GR.

Anyways the idea is to sort of reverse that,
so it results instead that light speed
arises from the relations of mass,
so that the lifetime of radioisotopes
and electrical current, help to go to show
that of course there abstractly _is_ a
derivation the other way around,
that perhaps if they never even thought
that SR's "mc^2, period", and GR's "mc^2
and the rest of the expansion which it is",
then it could be gently introduced these
multiple ideas at once, in case it may otherwise
be so that some radical SR'ians may violently
react to being told that their SR-first theory
was missing 99+% of the many terms of
the infinitary expression, of mass-energy
equivalency, which is usually used to explain
what the power of atomic bomb is and then
also what the power of matter/anti-matter
reaction would be.

Mostly though because then it would help
that the development would work up some
natural units as for example it's simple that
"SR-ians keeps some things simple at the
cost of others" that according to this sort
of E-principle or Energy-principle for the usual
L-principle or Light-principle, that, because
it's well known already what that is, that
the quite challenging mathematical
derivation as of "run analysis backward",
would yet help show for a simple category
diagram, various ways these theories and
their various relativity theories together,
are interpreted in terms of each other.
