Change of progress plans due to cancelled lecture (please read full message)

Due to the cancellation of the lecture today, the progress in theory and exercise sessions for this and next week will change slightly.

In Friday's (26/4-13) exercise class we will not do the assignment set for week 12, but rather go through some preliminary theory on theoretical physics, involving lagrangians, variational principles etc. with applications to scalar fields specifically.

In Monday's (29/4-13) theory class the subject of inflation will be motivated, explained and specified in terms of scalar fields, in essence all of chapter 3 will be taught. As background on scalar fields have been reviewed on Friday, details of this will not be emphasised here.

On the following Friday (3/5-13), we will do both the assignments for week 12 and 13, that is we will start by discussing the concepts from week 12's assignment and then go on to go through one or more of the exercises in week 13's assignement. The compulsory hand in of your solution to either problem 3.1 or 3.2 in the lecture notes is still due on this Friday.
