Time out from research

I've spent the last couple of days mostly working on revamping material for a course I'll be teaching this fall, which will be partially on-line. While I've used some on-line material before, this time I'll be taking it a little further. Instead of meeting with students three times a week, we'll meet twice a week, and the students will have assignments to do on-line the remaining day I'd normally lecture. This requires the on-line material to be a little more beefy than I've had before.
