Summary  NB. This course is delivered *biennially* with the next instance being in 202223. It is anticipated that it would then be delivered every other session thereafter.
This is a course on the calculus of variations and explores a number of variational principles, such as Hamilton's Principle of Least Action and Shannon's Principle of Maximum Entropy. The approach taken in this course lies at the interface of two disciplines: Geometry and Mathematical Physics. In Geometry you will learn about geodesics, minimal surfaces, etc. In Physics you will learn to elevate Newton's laws to a mathematical principle and discuss lagrangian and hamiltonian formulations. A running theme will be the relationship between symmetries and conservation laws, as illustrated by a celebrated theorem of Emmy Noether's. We will not assume, however, any background in either Physics or Geometry. All the necessary vocabulary and concepts will be introduced in the course.

Learning Outcomes
On completion of this course, the student will be able to:
 Derive the EulerLagrange equations for variational problems, including the case of general variations.
