(i) My scientific papers I wrote in the 70ies are about laser chemistry and photochemical reactions. In the 70ies and 80ies I was with Siemens AG concerned with laser isotope separation.  Because of competition with similar scientific groups in the US and other countries none of my papers were allowed to be published. However, some remarkable results would have been worth it, e.g. - for specialists only! - the high resolution UV spectra of  a big octahedral molecule which showed classical P-Q-R-structures at 30 Kelvin. Nobody had expected this at the time, because of some negative remarks of Edward Teller in Herzberg's famous book about molecular spectra. I don't know if then or even later any scientist discovered again those fantastic spectra.

Later, I buried all this and turned my interests to what I had missed most of all: rational thinking in our every day life; rational thinking as it is used in some scientific circles: imaginative and highly speculative thinking combined with phases of rigorous criticism.

(ii) Since the 90ies I published philosophical papers, gave public lectures and lectures at the Universities of Bamberg and Passau (Germany), and I wrote my first book  about critical rationalism. In this book I tried to generalize Poppers idea of rationally discussing metaphysics in a new way thus developping a new rational method of ethical thinking and decision making. I also stressed   the idea of critical rationalism as a general and very useful  method of problem solving. ...

Some of my philosophical papers are written in English, and of course the book 'Karl Popper and the Two New Secrets of Life', Tübingen (Mohr Siebeck) 2014.
