comment History of Gauss' Law
Dear Michael Spivak, you could give a look at this paper of Viktor Katz on the subject, I hope it is useful to you.ingelec.uns.edu.ar/asnl/Materiales/Cap03Extras/Stokes-Katz.pdf

comment what are the killing vector fields on a triaxial ellipsoid?
I have received two answers that are equally very interesting. My question was not restrictive on the kind of proof. Not being possible multiple choices, I have accepted the first posted answer.

comment what are the killing vector fields on a triaxial ellipsoid?
Dear Robert Bryant, I like this argument very much: going along the lines of your sketch, I should have the occasion to give a proof in closed-form. Your and Algol's answers are both very exaustive. Thanks you.

Dear Algol Thanks a lot for the proper reference, and for the explanation.

comment Schwartz space inequality
@Feynmaniac: About an approach which doesn't separate the two cases $|x|\ge 2|y|$ and $|x|\le 2|y|$: couldn't it be possible the following proof? 1)use the triangle inequality $|x|\le |y|+|x-y|$, 2)apply the binomial formula to $(|y|+|x-y|)^l$, 3)apply the hypothesis on $g$, and finally $|y|^k\le(1+|y|)^l$, for any $y\in\mathbb{R}$ and $0\le k\le l$.

comment Algebraic structures of greater cardinality than the continuum?
Dear Qiaochu Yuan: even if not an exact duplicate, the OP could read the answers to the similar question mathoverflow.net/questions/32370/…. Was you refering to it?
