My apologies for being slow this week ! I've been trying to churn out a little more data for a great talk (to be delivered by our own Andy Z) at the APS March Meeting.
The 2nd and final video for this week "More counting ... " is currently being processed by Panopto. The link should work soon.
I have every intention of finishing grading your work from Week 4 tonight (Monday). Your assignment for Week 5 will be out on Wednesday at the latest!
