Hi I am currently trying to learn quantum physics using David J. Griffiths textbook. However, in chapter 4 and 5 he lost me a little. I would prefer a textbooks that handholds me through solving the PDE's rather than just giving me the solutions. The topic of these chapters are: QM in three dimensions (Schrodinger equation in spherical coordinates, the hydrogen atom, angular momentum, spin) Identical particles (two particle system, atoms, solids, quantum statistical mechanics ) any tips? Maybe a mathematics or physics textbook to complement this?
