In this thread there have been a number of odd statements. I can't figure
out which are facetious and which are merely befuddled.
In current professional usage, "mass" means "rest mass". Indeed, saying
"rest mass" is a pleonasm, so I'll stop saying it. The "m" that appears in
equations like E = m c^2 is this mass.
