Chiral Quark-Soliton Model
  The Chiral Quark-Soliton Model of nucleons is based on two ideas: 1) the major role of spontaneous chiral symmetry breaking in hadron physics and 2) the relevance of the large number of colours limit for the real world. In these lectures I review the theoretical foundations of the model, the physics involved, and some of applications.   Contents:   1. How do we know chiral symmetry is spontaneously broken?   2.
