I'm looking for a book on statistical physics. One's I've used already are Huangs Intro one and Sachs/Sens/Sexton. They're both great and the problems are great but neither provide answers nor are there any solutions to be found online so I have no idea if I understand the material. Could someone suggest a book similar to these but with solutions available or even just answers? Or even better if someone knows of any online resource that has some solutions to the problems in either.
