Good news, I guess. In the course of the last few days I was able to wrap up the chapters in which I introduce the term envelopment (Einhüllung). Because of the seething heat I lost track of my work for a few days, first bathing in the North Sea, then staring at the screen without seeing anything. Either frustration with lack of progress or adaptation to the heat finally set in and pushed me forward again, so that now – for the first time – I feel that I have completed a significant part of my dissertation. It is now quite a bit longer than my diploma thesis. There is land at the other side of the sea of words. Ahoy!
