Course Description
This course aims to cover the following topics: the
Lagrangian, Hamilton, and Hamilton-Jacobi dynamics, canonical transformations, variational calculus and the least action principle, dynamics of
particles and rigid bodies, Green's functions, oscillations and normal coordinates. The relativistic dynamics, fluid dynamics,
nonlinear dynamics and chaos may be considered as time permits. The course will include
two lectures per week accompanied by a recitation.
