As catchy a phrase as Mati's sig line is, one is never a fool just by
mere association.

Here I simply mean that wordpress allows only the contributor to edit
his words. At least, I do not feel comfortable making any changes to
others' submissions, even if possible. I might as well make up fake
criticisms per my own fictional expectations in that case.

It's not _my_ claim, check your local News sites regards Einstein.
Nothing wrong about my choice of word "postulated." Per the Thesaurus,
I could alter it to one of:
postulate
verb
a theory postulated by a respected scientist: put forward, suggest,
advance, posit, hypothesize, propose; assume, presuppose, presume,
take for granted.

I kept dwelling on this and am comfortable with your total energy
equation. Each projectile can be m/2 or there can be just a single
projectile with mass m. Your derivation based upon total energy is
quite unique. So what's your take away conclusion?

In every Internal Combustion Engine, a small unmeasurably amount of

Have you noticed how many modern particle physics articles are
authored by more named individuals than there are total words in the
article itself?
