For all my close friends who I've chatted with about today's adventure: I'm home, and doing fine. But seriously, ouch.
I've been using StumbleUpon to find new webpages on a variety of subjects when I am bored, and as you might have seen from other blog postings (although not so many recently), mathematics is one of those things that I actually find kind of interesting to think about. While scanning around this morning, I found a link to the Feature Column from the AMS, which has many interesting articles on a wide variety of mathematical topics. I found the December 2008 article on the mathematics of clock making to be particularly interesting.
