1 week in Köln

Our theoretical paricle physics seminar group met for the fourth time and during this week we learned a lot about supersymmetry. In fact, we have become a "sgroup" ;-) (insider for physicists). In our (little) free time had a guided tour through Köln in the evening, visited the cathredral (Kölner Dom) where we spotted amazing details like a fireman and a steinbock (this word is indeed the same in German and English) on the facade! Of course we also climbed on 533 steps to the tower.
