Problem sheets

pdf files with the problems will be downloadable a few days before the problem sessions.

8/9 No class

15/9 Problem set 1

22/9 Problem set 2

29/9 Problem set 3

6/10 No new problem set - discussion of sets 1, 2 and 3

21/11 A take-home exam for extra credit can be obtained from Pablo or Ana. It is due on the day of the exam, December 7th.

Final exam: Wed 7/12, room Huygens 106/107, 14:00 - 17:00

It will be a written exam. There is a first part without book (about one hour) and a second part with open book. To the first part you can bring a one-page summary (formulas, etc). The conditions for the second part are: you can bring a) Povh, Griffiths and another book, b) van Holten's notes, c) your own handwritten notes from lectures and werkcolleges (including your own solutions to the problems - no photocopies), d) a calculator.

The final grades for the course can be found here . Please contact me (by email) if you want to check your grading and/or if you are intending to take the resit exam.
