Lie groups and their algebras arise most often in physics as symmetry groups of dynamical systems. These symmetries are intimately associated with conservation laws. For example, if a physical system is invariant under translations then its linear momentum is conserved; while rotational invariance of a system implies conservation of angular momentum. In modern physics the symmetry groups are not only the geometrical symmetries of space-time, but also new symmetries associated with “internal” degrees of freedom of particles and fields. These symmetries lead to the conservation of more exotic quantities such as isospin, strangeness, charm, etc.
