Description
This module introduces some fundamental concepts in analytical dynamics, and illustrates their applications to relevant
problems. The module covers the calculus of variations, Lagrangian and Hamiltonian formulations of dynamics, Poisson brackets,
canonical transformations, and HamiltonJacobi equations. The approach is necessarily mathematical and students are advised to
take this optional module only if they have got marks of at least 60% in both PHY1021 Vector Mechanics and PHY1026 Mathematics for Physicists (or in equivalent modules in other departments).
Module Aims
This module will be of interest to students wishing to develop their grasp of theoretical physics.
The subject of analytical dynamics provides advanced theoretical developments which prove elegant and versatile in solving
dynamical problems.
Intended Learning Outcomes (ILOs)
A student who has passed this module should be able to:

Module Specific Skills and Knowledge:
 solve advanced dynamical problems involving classical particles by applying the Lagrangian and Hamiltonian formulations;
 explain the calculus of variations and apply it to the solution of problems;
 state the HamiltonJacobi equations and apply them to the solution of problems;
 describe the relationship between poisson brackets and quantum mechanical commutation relations;
 describe the basic concepts of chaos theory and explain how chaos theory may be used in different disciplines;

Discipline Specific Skills and Knowledge:
 formulate mathematical descriptions of physical systems;

Personal and Key Transferable / Employment Skills and Knowledge:
 use mathematics to solve problems.
