User:Paul Wormer

I retired in 2005 from the Radboud University in Nijmegen (The Netherlands) as an associate profesor 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. My research interests are on the crossing of Chemistry, Molecular Physics, and Applied Mathematics. My cum laude Ph.D. thesis was on Group Theory and Intermolecular Forces; both topics still hold my interest. Several times I held an appointment as a visiting research professor in Applied Mathematics at the University of Waterloo in Ontario. From October 2006 until August 2007 I contributed to Wikipedia under the name P.wormer.

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