Books

During years of teaching I got some expirience. Some things were evident to me but not to others. To explain these things I started to write. Strangely enough I wrote not articles but books. I don't like long explanations and try to write short. So my books are mainly thin. To avoid monologues I first discuss my texts with my friends. They have clever ideas too, so we usually write together. Here you can see the results of our work.
