If you prefer to read a printed copy

... then you can buy the first German edition! I have asked some English and American publishing houses, but hardly got any reaction. I will not ask them on my knees.

The printing of the German edition was possible thanks to generous sponsoring by the following companies and private persons:

sia Abrasives Industries AG, Frauenfeld
Bruker BioSpin AG, Fällanden
Kantonsschule Frauenfeld, Frauenfeld
Hans M. Streit, Dr. sc. nat., Frauenfeld
Stefan Casanova, dipl. natw. ETH, Frauenfeld

I would like to express my gratitude here again. So you can order a paper copy at a extraordinary low price.
