This chapter briefly describes those activities which were initiated to stimulate scientific life in Chemnitz and exchanges with the physics community, i.e. meetings, conferences, summer schools etc.
In the tradition of the "Heimbach" meetings of Wolfgang Richter's group in Berlin and after a first joint meeting "Heimbach VII" in Oberwiesenthal from September 26th to 30th 1993, the group organised their own meetings named after the first host place Holzhau from 1995. The idea is to combine work and leisure in a place remote from the university and daily duties. These multi-day events clearly provide an atmosphere for enhanced scientific exchange amongst group members and a few guests. The programme of talks and discussions interrupted by e.g. hiking in the Saxonian hills has become an important ingredient of scientific and social life. The latter is positively influenced by the high quality of Saxonian beer served during the evening sessions.
