Last chance to ask about the midterm question

During our discussion today it became clear that there are some questions that few students have had time to think about yet, and which there might be some of you who would like to as about or discuss. We therefore agreed to have an additional meeting on Friday in room FV414 (physics building, 4. floor west) at 10:15. Otherwise, you can always send email or come to my office if you have problems (but I am absent the rest of the day today and all day tomorrow).
