The Epicycles of Life

So it's turning out that I am hanging around a bunch of molecular biology, where PCRs and various -ases happen in daily conversation. The daily commute over the Bridge of Death is a part of life, as long drives once were, and I know this area about as well as I knew Detroit back when the Auburn Hills/Ann Arbor corridor was where I tended to live. Now it turns out that I am starting a project to build a production-based deductive inference system, along the general lines of one I used at the U-M AI lab. It is early summer. Similar things prominent on the mental landscape to ones that happened during my master's time, with one exception.
