comment Invariance of Lagrange on addition of total time derivative of a function of coordiantes and time
There isn't an absolute path in Galilean mechanics, the paths ARE different in the two frames where $x' = x -Vt$

comment Why do both plates of a capacitor have the same charge?
user41086's point is a good one. KCL is concerned about currents at a single node, not at multiple nodes.

comment Does the action and Lagrangian have identical symmetries and conserved quantities?
Welcome aboard. Maybe you could click on "tags" or "unanswered" at the top to answer the difficult questions and get your rep up.

comment Discovery of $E=hf$?
@DImension10AbhimanyuPS probably after the edit was added: "The Plank law was first a fit bridging two experimental asymptotics. But it worked so well for different T and with a unique h that Plank started to "derive" this law and introduced those quanta"

What did you use to make the great diagrams?

comment Introduction to string theory
It got five stars on amazon.co.uk so I'm interested in studying from it. With its 700 pages, I guessed it would take me at least a year to read, if I spent two hours every day on it, so I was curious how long it took you.

comment In the topos-theoretic interpretation of Physics by Isham & Doering what role does intuitionistic logic play?
Even if this question can't be answered here at the moment, it'll inspire a few to perhaps learn more about this fascinating subject.

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?

comment Independancy of angular momentum with respect to origin for rotation about center of mass
+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.

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

I don't understand your answer at all, but thanks for the effort.

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.
