I'm a guy who knows a bit of physics. I've been participating in the Wikipedia since December 10 2001, and have written a fairly large number of articles, mostly on physics (particularly quantum mechanics and related topics.) Some of these are listed below. Apart from that, I have written an Emacs major mode for editing Wikipedia articles offline, which can be found at wikipedia-mode.el.
