I retired in 2005 from the Radboud University in Nijmegen (The Netherlands) as an Associate Professor in Theoretical Chemistry. Over the years I (co)authored about 150 research papers published in journals as "the Journal of Chemical Physics", "Molecular Physics", "Physical Review A", etc., see here for a fairly complete list. I got a (cum laude) MSc in Chemical Engineering, but after an internship at a Haber-Bosch plant I decided that Theoretical Chemistry was more my cup of tea. My (cum laude) Ph.D. thesis was on Group Theory and the Theory of Intermolecular Forces; both topics still hold my interest. Most of my working life was on the crossing of Chemistry, Molecular Physics, and Applied Mathematics. Several times I held an appointment as a Visiting Research Professor in Applied Mathematics at the University of Waterloo in Ontario. I was a Visiting Fellow of the Royal Society in Bristol and a Visiting Professor of Theoretical Chemistry in Warsaw.

From October 2006 until August 2007 I contributed to Wikipedia under the name P.wormer. After my relatively late arrival at WP I found that most basic science articles were already in existence, so I added mostly to the niche of more advanced, graduate level, science. After a probation period of nine months I got fed up with continuously defending my work against attacks by science illiterates and fled to Citizendium. On CZ I soon discovered that this encyclopedia was almost virginal and that the foundation in science still had to be laid. So, I will add as many basic science articles as I can to CZ.

I am not a native speaker of English and appreciate it very much when my grammar/spelling/wording is improved. I hate it, however, when content that I contributed is removed without good explanation (in the associated talk page or my personal talk page). So, please, if you feel it necessary to delete some of my work (and possibly replace it with something else), explain to me why you think so. I may even agree with you! In Wikipedia I was sometimes criticized as being too abstruse and I had to agree with that several times, after which I tried to do a better job. So, please let me know if you don't understand my writings; together we can make something nice.

CZ articles

On May 18, 2008 I prepared the following list of 116 CZ articles of which I am a main author (I didn't recheck all articles when preparing this list, so it is possible that to some articles additions may have made that are more important than my contribution).
