It’s done, the “book” is now written, published, and defended. It’ been quite a journey – starting in autumn 2002, working through two research projects, countless (well, almost) teacher assignments on courses, working on the competing home-project (two kids – 2004, 2006). Although the journey never ends, the disputation defense was a welcomed station on the way. The opponent, Prof. Michel Leonard did a very good job of examining the thesis – and I hope that I was not as clueless at it looks on the picture when it comes to answering the posed questions. (Thanks to Nasrin for taking the great action picture!)
