comment Lagrange Multipliers Versus Generalized Coordinates
@bolbteppa but aren't you asking how Lagrange's equations of the first kind are equivalent to the Euler-Lagrange equations?

+1, it would be more readable if you used $r'_{i}$ for the new coordinates.

comment Would it be possible to develop special relativity without knowing about light?
@Dimension10 wise words from... you're only 13? I'm shocked and awed at the same time.

@Dimension10 please flag it under other as "too localized" so we can close it.

comment Why do we still need to think of gravity as a force?
@SachinShekhar the source of gravity is mass and its effect on space-time

comment What's the purpose of the arbitary additive constants in Einstein's Inertia of Energy Paper?
+1 OK, that's much better, which is what John McVirgo says in the comments of the question.

Ok then, so why didn't Einstein also account for different energy scales, such as temperature, having different multiplicative factors?

-1 he didn't bother with different frames using different standards of measurements in his 1905 paper, so it's safe to assume he didn't do the same here, otherwise he would have said so.

comment What are hidden variables exactly?
@user21847 our ignorance and inability to measure these variables hides them from us.
