By use of examples from classical mechanics and electrodynamics, the definitions of invariance by space symmetny of intrinsic purity'' and orbitul parity are derived. Then, in quantum mechanics, the possibilities of intrinsic parities are discussed for 0 and 1/2 spin particles with nonvanishing and vanishing (neutrino) rest mass. The Weyl (two component) theory of the neutrino is given. The quantum field treatment of emission and absorption processes is shown, and the total parity conservation theorem is given for P (spatial symmetny) invariant interactions. The experiments of C. S. Wu et al., and of Barwin et al., and of Garwin et al., suggested by the Lee-Yang theory are described. In conclusion, experiments show the P and C (charge conjugation) non- invariance in weak interactions. The Luders-Pauli theorem is mentioned, and the Landau hypothesis of PC invariance is given.
