Symmetries and Symmetry Breaking
In understanding the world of matter, the introduction of symmetry principles
following experimentation or using the predictive power of symmetry principles
to guide experimentation is most profound. The conservation of energy, linear
momentum, angular momentum, charge, and CPT involve fundamental symmetries. All
other conservation laws are valid within a restricted subspace of the four
interactions: the strong, the electromagnetic, the weak, and the gravitational
interaction. In this paper comments are made regarding parity violation in
hadronic systems, charge symmetry breaking in two nucleon and few nucleon
systems, and time-reversal-invariance in hadronic systems.Comment: 5 Pages, LaTeX, 2 PostScript figures. Talk at 17th International
