1. The Discoveries of Particle & Nuclear Physics Models and Experimental Facts

2. Background  Discoveries of electron, proton and neutron & quantum mechanics promoted to investigate inside nucleus. (Beginning of nuclear particle physics)  The idea of nuclear force, which used to be the strong force, was given as exchanging particles. (Meson exchange model)

3. Background (cont.)  Accelerators made tons of particles. (Subatomic zoo, mesons, baryons, etc.)  The existence of the internal structure of meson and baryon led to a more profound idea of elementary particles. (Quarks)  A number of particles were classified and explained as models and theories. (Quark model, group theory, QCD, etc)
