My name is Axel Boldt and I teach mathematics at Metropolitan State University in Saint Paul, Minnesota. In addition to mathematics, I'm interested in molecular biology, theoretical computer science, physics, astronomy, free software, (political) philosophy, chess, and many other things. My home page is at http://math-www.uni-paderborn.de/~axel/.
Since I believe that "intellectual property rights" do not exist (as we mere mortals cannot arrogate the right to own parts of Plato's eternal heaven of ideas), every word I write is by default, and always, in the public domain.

[edit] Wikipedia writings
- I think that Wikipedia would be much improved if only people who have provided their real name were allowed to edit the encyclopedia. See real name proposal for the details.
- Let's switch to the CC-BY-SA license
- Adding references to statements in Wikipedia, while useful, does not increase the trustworthiness of the encyclopedia. See References don't increase Wikipedia's reliability.
- I am against advertisements on Wikipedia.
- Notes for a talk about Wikipedia I gave in 2006: Wikipedia Talk.
- How to let go and prevent burnout as a Wikipedia editor: An article is a collection of revisions.
- The support software I endorse for editing Wikipedia: Support Software

 Awarded to AxelBoldt, for being an outstanding contributor with a plethora of fine contributions, particularly to mathematics articles, the barnstar of math and science. Herostratus 17:20, 13 March 2007 (UTC) |
I award this barnstar to AxelBoldt for giving us WikiMoney! (Sorry this is a bit late.) Einsteinewton 05:57, 7 November 2007 (UTC) |
Brewcrewer, a newpage patroller, rarely comes across any great new articles, but when he does, like the Solingen arson attack of 1993, he can't help but plaster its creator's talk page with a barnstar. brewcrewer (yada, yada) 04:52, 27 May 2008 (UTC) |
