General Relativity (U01429)

? Credit Points : 10 ? SCQF Level : 11 ? Acronym : PHY-5-GenRel

General Relativity presents one of the most interesting intellectual challenges of an undergraduate physics degree, but its study can be a daunting prospect. This course treats the subject in a way which should be accessible not just to Mathematical Physicists, by making the subject as simple as possible (but not simpler). The classic results such as light bending and precession of the perihelion of Mercury are obtained from the Schwarzschild metric by variational means. Einstein's equations are developed, and are used to obtain the Schwarzschild metric and the Robertson-Walker metric of cosmology.
