in theory moves

We ring in the year of the rat with a move to wordpress, and to its superior handling of latex.

Please update your bookmarks, your RSS readers, and your blogrolls, to

While all old posts and comments are there, the move has broken the latex hacks, the videos, and the cross-links between posts. This will be taken care of in the "near" future.
