Sections on equilibrium statistical mechanics address general principles of many- particle systems, perfect gases and their properties, and quantum systems with strong interactions.
Nowadays, there seems no option but to allow for the effect of strong interactions by introducing the baryon weak and electromagnetic form factors.
