    Computational Metaphysics and The Ontological Argument:
News: Our lecture concept on Computational Metaphysics won the central teaching award of Freie Universität Berlin. More information on the course: lecture course proposal and website/schedule.

Visitors of my website are often interested in my ongoing work (in collaboration with Bruno Woltzenlogel Paleo) on the verification and automation of variants and emendations of Kurt Gödel's ontological argument for the existence of God. This work had a media repercussion on a global scale. There are various articles (e.g., Spiegel Online Intl., Die Welt, Wiener Zeitung, Spiegel Online) and interviews (e.g., Telepolis, PC Zoznam, Detector.fm, ORF); a selection of further links to reports worldwide is available here. Unfortunately, and probably unavoidable, there are also a few ill informed, trashy reports like this one. If you want to learn more about our scientific work (and about what we did and what we didn't), then you may have a look at our (peer reviewed) papers at IJCAI-2016 and ECAI-2014 conferences; see also the references therein. Btw, our experiments reported can be recomputed on various computer platforms; a convenient way is to use the experiment package at recomputation.org. Formalization sources, papers and various other related material are freely accessible via our github repository.

I am still a passionate middle and long-distance runner. In the early 90's I lived and trained at the Olympic Centre in Saarbrücken. In 1990 I was German Champion with the men's team in cross-country running. Feel free to beat some of my personal records: 2:25min (1000m), 3:49min (1500m), 8:14 (3000m), 14:13min (5000m), 30:04min (10000m). I am still occasionally starting in some street races; here are some results. Since around the same time, I have also become an enthusiastic diver. Furthermore, I like skiing.
