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 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 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.
