Symmetry Principles in Solid State and Molecular Physics

This is the authors' abstract. We don't add key points for this paper.

If good books on symmetry were assigned to a spectrum running from the gold mine to the jeweller's shop, then this one would definitely appear in the somewhat sparsely populated region right next to the gold mine. The title is to be taken literally, the realized aim being not to interest the reader in group theory, (several crucial theorems are quoted but not proved), but lo teach him by precept and example how to apply it in realistic detail to nontrivial physical problems.
