1.5 Neutrinos
The indeterministic electron energy in beta decay raised a requirement of new particle produced in the reaction, recalling Powell’s emulsion picture indicates this new particle should be electrically neutral, eventually led to the family of leptons.

1.2 Photon
solution of Compton scattering may also serve as an exercise of relativity


1.1 the Electrical Era
from J. J. Thomson’s discovery of electron to Bohr’s model of hydrogen


This is an introduction to Griffiths’s classical textbook of Elementary Particles
