<p>So apparently there's a newer version of the Intro to Electrodynamics by Griffiths textbook (4th edition) that just came out but the course says the required text is the 3rd edition. Will they be using problems from the book (and thus the version matters) or will it just be reading assigned from that book? Thanks.</p>
<p>Depends on the professor. This fall’s 110A homeworks were all written up independently of the book, and I think this is pretty typical… Can’t say for sure though, so hopefully someone who’s had Wang before can chime in.</p>
<p>Yeah I just emailed him and he said either edition is fine! Thanks!</p>
