comment Electric field. Linear charge density
That looks correct to me. Are you looking out for unit conversion, i.e. nC to C, cm to m?

comment Book covering Topology required for physics and applications
Sorry, I haven't heard anything of that book. However, judging by the absolutely ridiculous price on Amazon... Anyway, I was also flipping through Nash and Sen's book, and it seemed to treat topology in a very intuitive and clear manner, although at a mathematical price - Amazon reviewers claim that it isn't too mathematically rigorous/comprehensive.

comment How to prove Wick's Theorem (Zee's eq. I.2 (16)) via Gaussian integration?
Ah, got it! I had been doing exactly what you suggested @LuboŇ°Motl, it's just that I was making a silly arithmetic mistake. Thanks for the help, guys! (In hindsight, of course 1 (and all odd multiplicities) would vanish - the integrand is odd!)

Huh, I did so on paper, but I was too lazy to write it out here in LaTeX. I'll try it again haha, sorry!

comment Free particle propagation amplitude calculation
Well yeah, definitely - that would explain the vanished $4\pi$ and the $dp\;p$. But how did the exponential become a sine and how did the $\theta,\phi$ integrals integrate out trivially?
