Lecture recordings available

I’ve posted recordings from this week’s lectures on YouTube.

I’ll try to record my lectures and get them online promptly this semester. I expect that most students will be coming to class anyway. So this is as much for my own reflective learning as for anybody else. But if you benefit from them being available, so much the better.

Unfortunately, the second video is only 6 minutes long. The mic battery died, and I decided there wasn’t much point in uploading a bunch of video with no audio.
