Aims
To introduce the basic ideas of Einstein’s theory of general relativity. To introduce a basic understanding of differential geometry needed for general relativity.
Module summary
Newton’s theory of gravity, based on the idea of a force of attraction between any two bodies, reigned supreme for about 250 years. In 1916 Einstein banished the notion of a gravitational force to the realms of history with his formulation of the theory of general relativity. This theory is based on the novel idea that the three dimensions of space and one dimension of time be treated as a unified 4-dimensional manifold called spacetime. The presence of matter bends spacetime from its flat Euclidean form, and what was thought of as the presence of an attractive force is now understood as the motion on this curved spacetime geometry. (Matter tells spacetime how to curve; spacetime tells matter how to move.)
The proper mathematical setting for Einstein’s theory of curved spacetime makes use of differential geometry. Because differential geometry plays an important role in other areas of mathematics and mathematical physics, we will spend the initial part of the course developing the necessary machinery in some detail. After encountering the needed mathematical ideas we will present the Einstein field equations, and then study some of the standard solutions. This will lead us into the study of black holes and the classic predictions of the theory of general relativity. We will stress how it is that Einstein’s theory makes different testable predictions from Newton’s theory of gravity.
Outline Of Syllabus
Definition of a manifold; tangent and cotangent spaces; vector and tensor fields; the connection, parallel transport, and covariant differentiation; the curvature tensor. Applications of the mathematics to general relativity; spherically symmetric solutions to the Einstein equations; Schwarzschild solution; perihelion precession, light bending, radar delay; black holes and Hawking radiation.

Teaching Rationale And Relationship
Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Tutorials (within lectures) are used to discuss the course material, identify and resolve specific queries raised by students and to allow students to receive individual feedback on marked work. In addition, office hours (two per week) will provide an opportunity for more direct contact between individual students and the lecturer: a typical student might spend one or two hours over the course of the module, either individually or as part of a group.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
A substantial formal unseen examination is appropriate for the assessment of the material in this module. The coursework assignments are expected to consist of six written assignments of equal weight: the exact nature of assessment will be explained at the start of the module. The coursework assignments and allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose as well as their primary summative purpose.
