John, I think you might want to re-think your equation div
E(x,t)=4\pi\rho(x,t).

It is not my equation--- it is the first Maxwell equation (expressed
using Gaussian units). I did not make it up, nor did I add the
time-dependence as another poster suggested.

Different texts have Maxwell's equations in different order. What text
did you get this from? Becker has it (in Gaussian CGS units) as
div D = 4\pi\rho (where the backslash indicates multiplication, and D
and rho have the usual meanings. You can add the 't' if you want to, but
it's unnecessary. Also, since you're dealing in 3 dimensions, why not
indicate them as in E(x,y,z), or E(x,y,z,t) (if the time means something
to you)?
