Jan 21	comment	What does this quote about the four dimensional divergence of an antisymmetric tensor mean? @joriki I'm the one who voted to migrate to physics.stackexchange. It's true that the OP is asking about mathematical terms, but I suspect that someone familiar with the underlying context (ie the physics of light) might be better equipped to answer the question.
Dec 30	comment	Why does the nature always prefer low energy and maximum entropy? Of course, this raises the question of why entropy doesn't also increase into the past.
Jun 25	comment	Why didn't Newton just propose the 2nd Law and leave it at that? Fair enough, although you wouldn't need to postulate the third law as a separate "law"; it would be a consequence of the symmetries of the potentials you plug in.
Jun 25	comment	Why didn't Newton just propose the 2nd Law and leave it at that? However the third and second law could be condensed into an Only Law: $m\ddot{q} = -\nabla V(q).$

Jun 23	comment	what is the 2D gravity potential? If their velocities are all also colinear, then yes, I would have expected so...
