I'm a student in a master's program, and of course I am working through the obligatory Jackson textbook. I can't help but wonder how useful this is going to be, how applicable. Let's face it, the book does little to further my insight into the actual physics. It's more of a treatise on mathematical methods. Should I be concerned that my knowledge of physics isn't furthered by this text? if I go on to a ph.d program then I'm certain I'll be seeing this book again, perhaps a second go around would help cement the material? Has anyone gained a deeper appreciation for the book after actually taking the course?
