Which textbook are you referring to that told you that the MMX was the

I'll point out to you that "The Physics of the Atom" is a book about
atomic physics, which has a scant review chapter on relativity,
providing light background material only, and only insofar as it
pertained to the central subject matter of the book. It is NOT to be
taken as a good reference for relativity or for the historical
development of relativity, and in fact it gets much of the historical
development wrong.

If you'd like some better references for the conceptual basis or the
historical development of relativity, I could certainly suggest a half
dozen much better ones.

Sigh, this is so sad.
