How Is Nature Asymmetric ? 1. Discrete Symmetries in Particle Physics   and Parity Violation
  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.
