Hmm... Thanks alot. I didn't realize how relevant Maxwell's equations still are. I was under the impression that they just get superseded when you move on to non-classical physics, as does Newtonian gravity (in my understanding).

Excuse me if this is a stupid question. I'm now studying Electricity and Magnetism, and I'm coming toward the end of the course. The thought has been crossing my mind recently of what a shame it is that Maxwell's Equations turned out not to be correct, seeing as they are so beautiful and...

Sorry. It's a layer of charge. The cases referred to here are an infinite flat sheet of charge with uniform charge density, a spherical shell of charge with uniform charge density and then finally any old layer of charge, saying in each case that from one side of the layer of charge to the...

I'm reading the book "Electricity and Magnetism: Vol. II" by Edward M. Purcell, in which he describes Gauss' law as stating that the flux through a closed surface is 4π times the enclosed charge (he uses the Centimeter-Gram-Second system). Later, he refers to Gauss' law as stating that the...
