Exercises
The exercises will take place every Friday 1618h c.t. in AVZ I, Room 0.033. Exercise sheets are handed out Wednesday and will be collected the second Wednesday after it has been handed out. Please work together in groups of up to three (not mandatory but highly recommended). Problem sheets will be discussed in the same week they are handed in. The week after, we will answer questions about the lecture, give detailed calculations or take our time to elaborate the problem sheets in more detail.
The tutors are Michael Kajan (kajan(at)th.physik.unibonn.de) and Marvin Lenk (mlenk(at)th.physik.unibonn.de).
