Thank you, Qmechanic. Mar 12 comment How is Gauss' Law (integral form) arrived at from Coulomb's Law, and how is the differential form arrived at from that? I intuit equation (2), but why cube $\delta(\mathbf{r}-\mathbf{r_i})$? Mar 12 accepted Proof that flux through a surface is independent of the inner objects' arrangement Mar 12 comment Proof that flux through a surface is independent of the inner objects' arrangement @joshphysics Thank you; yes I do. It's finally clicked where that derivation fits in to the derivation of Gauss' Law. Thank you all for the patience!
