This two-part article considers certain fundamental symmetries of nature, namely the discrete symmetries of parity (P), charge conjugation (C) and time reversal (T), and their possible violation. Recent experimental results are discussed in some depth. In the first part of this article we present a general background and discuss parity violation.

In this second part we discuss the violation of two discrete symmetries, CP and T, which follows our discussion in general of the discrete symmetries C, P and T, and that of parity violation in Part 1. We conclude with a synthesis of the ideas presented in the two parts of this article.
