After explaining why pions are special excitations in QCD, I discuss how the pion mass reflects directly the dynamical scale of the strong interactions (AQcn) and the scale of breaking of the weak interactions (AF).To actually calculate the pion mass, however, requires understanding the origin of the quark masses and so I compare and contrast approaches to this latter problem, based on composite models and on superstrings.§ 1.The pion mass in QCD-dynamical issues
