from Jackson's own institution, we aren't actually doing any problems out of the text.
If you ever see Charles Kittel wandering around Berkeley, please flip him the finger. He deserves to be banished from the physics community after writing that atrocious solid state book, regardless of anything good he may have accomplished.
The proliferation of solutions manuals on the internet has doubtless made problem sets from the book obsolete.
That's one of the reasons I'm glad we're not given course grades, especially since we're responsible for the prelim and general exams, which will test the same material and be plenty difficult themselves.
I haven't read far in Jackson yet, and I don't expect it to be easy, but I'm actually very pleased with some of the preliminary things in the text. Someone FINALLY explained to me precisely what it means to ground a conductor, and how it can be accomplished (*experimentally) to arbitrary precision. Previously, all profs would say to me is V=0, which is hardly satisfactory. They'd constantly say that grounding a circuit anywhere doesn't affect the circuit, but then i'd say what happens if you ground it in two places? They say then it gets shorted, so how can they say it's unaffected the first time?
Similarly for the grounded plane examples in Griffiths, does it matter where you ground the plane? Afterall if you ground it near the origin (which is what the diagrams for the problem often suggest), the ground wire itself will have a charge buildup that may affect the surroundings... etc... but anyway, all I'm saying is that Jackson's in depth analysis finally shed light on those matters. Also, he finally explained that Coulomb's law is indeed the underlying law of electrostatics, and that the Maxwell equations for div/curl of E were derived from it for solving problems where you don't know the charge distribution! And then he directly derived how the integral equation for V satisfies poisson's equation etc... So it looks like if I want to learn E&M once and for all, this is the right book.
