K = m c^2 - m_0 c^2 = 1/2 m_0 v^2 + 3/8 m_0 v^4/c^2
+ 5/16 m_0 v^6/c^4 +...

There's also an odd error in the derivation of (11) from (10).
Since m = 0, the values p^2/2m and hbar^2 k^2/2m have no meaning.
In fact as written the equation makes the odd claim that

p^2/2m = pc

or p = 2mc = E/c.

This is not quite consistent.

One might claim is that m_0 of a photon is zero
(since photons are never at rest); since m = gamma m_0
and gamma for a photon is infinite (1/sqrt(1-c^2/c^2)),
a special case can be made available. Therefore
m = 2E/c^2 is reasonable, although it's not clear if it's
actual mass, as opposed to an abstract formula. However,
that doesn't reconcile with (8) or (9), either.

But what if they lose them?
