Ups, but still you didnt clarify what you are talking about. But what i wrote does not translate to what you wrote you see, M does not equal m, C does not equal c and E does not equal e. Its like linux, capital letters matter and mean completely different things.

(SQR means Square root)
Notation aside, what is your point? This algebraic manipulation is trivial.

You think there is one?

"Ups"? I don't know what United Parcel Service has to do with it either.

But that's true, E does not equal e. I was lazy about capitalization.

I'm giving him the benefit of the doubt (iow, enough rope for a workable noose).

8. I'll do obvious thing and go through the damn algebra. Why not.
• MC = SQRT(EM)
• (MC)^2 = EM (square both sides)
• M^2 * C^2 = EM (distribute square)
• M * C^2 = E (divide both sides by M)
• E = MC^2 (rearrange that stuff)

If E = e (notation for energy), M = m (notation for mass), and C = c (notation for speed of light), and if e = mc^2 is intended to represent that ol' famous general relativity equation and is assumed to be true, then the original statement is true.

(aside from stupid technical stuffs, e.g. potential division by 0 in step 4 there, which limits the domain of the equation etc. etc.)

9. Genius level = ENFJ!
