Revision

3 lectures in Easter Term, one by each lecturer

Teaching methods

Lectures: 2 or 3 one-hour lectures per week.

Workshops: These provide an opportunity to work through and digest the course material by attempting exercises and assignments assisted by direct interaction with the lecturers and workshop leaders. Students will be divided into four groups, each of which will attend one one-hour class every two weeks.

Problem exercises: See http://www.dur.ac.uk/physics/students/problems/
