On reviewing your one history you are always biased and tend to rewrite it silently. You might consider that bias positive, recapturing Viktor Frankl's saying of flooding the entire life with meaning in retrospect. I am keeping the old versions of my web pages and force myself to re-read, comment and gradually change them. The CV tends to become cluttered, therefore I am providing a current version (2011) which is neither complete nor objective.
I always wanted to know how stuff really works and what makes human beings behave the way they do. As a child I have dismantled a toy car in a way that the grown-ups could not reproduce. I grew crystals of potash alum and blue vitriol (until I destroyed a not so heat resistant glass) and crafted paper polyhedrons (the largest in terms of no. of surfaces was a rhombicosidodecahedron with pyramids on each surface). Later I fired pulsed laser beams on little lumps of ceramic material, took photos of the emitted cloud of evaporated material and let thin films grow from this material. I have tried to understand why this clouds protruded into space in a very peculiar shape and why the electrical resistance of these films became zero at low temperatures (or not).
I was most interested in the reason why (things were as there were). It seemed less important to me to build something useful based on these insights. But I became more and more involved in the latter. Probably this was based on my investigations of the human behavior. Or rather the behavior of systems constituted by human beings. I learned what is required, important, right or opportune. As a small particle in large systems I have made some contributions. Today I am still under the impression of the ambivalent nature of of being the 'techie who saves the world': Fame and glory versus burnout and stoic self-descipline.
Reading the book of my life I am detecting the following recurrent theme: Since nearly 25 years I have been explaining technical and scientific stuff. By explanation I mean the transfer of low-level understanding - of 'talking and thinking science' in the language of mathematics - into examples, action, and stories. I am a true fan of Richard Feynman.
