Summary
This module highlights two important concepts in theoretical physics: (i) symmetry and (ii) variational, or action, principles. Symmetry is a powerful notion, both in the development of theories of physical phenomena and in the solution of physical models. In this module the basic aspects of the mathematical language of symmetry will be introduced and applied to a range of physical phenomena. The principle of least action, introduced in Principles of Dynamics, will be further developed. In particular the notion that symmetry principles can be most simply incorporated at the level of the action for a physical system will be considered in detail. The relationship between the presence of symmetries and conservation laws will be explored and the notion of broken or hidden symmetries will be introduced.
