To be honest, I don't have much time to spend on this Wikipedia thing. But as long as I'm here, I figure a little bit of information about myself is in order.
I am a visiting professor of physics at the Claremont Colleges with a specialty in string theory that I continue to study as my teaching duties allow. (I received my Ph.D. in physics at the University of Chicago; as an undergraduate I was at Harvey Mudd College.) In the spirit of sharing my excitement about science with others, I gave a short speech at a scholarship luncheon in the fall of 2003 on the value of science which was fairly well received. Early in 2004, I gave a lecture on the basics of string theory to Chicago's MIT alumni club, which a number of people have found interesting.
I have also been an active participant in the J. R. R. Tolkien newsgroups on Usenet; I am the author of the groups' current FAQ and a number of related resources and essays (most notably the Tolkien Meta-FAQ, my exhaustive essay on Tom Bombadil, and the Custom Tolkien Book List). As a fun aside, I was elected prom king back in high school as a result of a massive practical joke by some of my friends; I've written up my full prom king saga to share the humor with others.
