Hi, I have to study for a solid state physics course and I'm not sure what textbook would be the best. Our professor suggested "Principles of the theory of Solids" by Ziman, or "Solid state physics" by Ashcroft. I'll intend to use both: one I buy, the other one I borrow from the library. But which one to buy ? Also I noticed that our professor didn't assign any exercise during the course... Is It normal for a grad physics course ? I'm majoring in nuclear engineering so I do not really know how a physics grad course should be. I intended to do some problems but Ashcroft's book doesn't contain problems. Is it good or bad ? The exam is an oral examination.
