comment What is a tensor?
A tensor is a geometrical object whose components transform like that of a tensor.

comment How does the speed of electrons change around a circuit?
The drift velocity is typically around a few centimeters/hour.

comment Why Lorentz Transformation in Special Relativity has to be like this?
You've thought about this before, right?

comment What transformation is the metric of general relativity invariant under?
@Siva Tullio Levi-Civita does both in his original book. I get the feeling that physicists skimmed over it, and just took out the bit defining a tensor as having components transforming in a certain way.

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.

awesome question!

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"

comment If electromagnetic induction generates a potential difference in a loop, where are the “high” and “low” potentials?
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?

Looks nice - very arty ;)

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.
