Taught Modules

PH-220 Stellar Astrophysics

This module will introduce students to the quantitative physics underlying the formation, evolution and eventual demise of stars. Students will learn how fundamental concepts from diverse areas of physics, such as gravity, thermodynamics, statistical physics and quantum mechanics come together to provide a complete mathematical model of stellar dynamics which is in beautiful and comprehensive agreement with observational data.
PH-355 Mathematical Methods in Physics III

This module introduces a range of important mathematical skill for physicists including advanced techniques for solving differential equations, variational method and group theory. These ideas will be illustrated with applications to well known physical systems.
