comment How is Gauss' Law (integral form) arrived at from Coulomb's Law, and how is the differential form arrived at from that?
Thank you, Qmechanic.

I intuit equation (2), but why cube $\delta(\mathbf{r}-\mathbf{r_i})$?

@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!

I'm happy that the divergence theorem holds for general surfaces, but not $\nabla \cdot \mathbf{g}= - \rho G 4 \pi$ that needs to be put into the divergence theorem to get Gauss' Law.

@joshphysics I hope it's clearer now, and yes, that was what I was looking for.
