I think it’s fairly obvious that posting from me is going to be erratic, and this trend will be even greater this week as we wrap up the first half of the spring semester. (Not that the details are important, but I am giving and grading two exams along with starting two new lab activities, plus a backlog of grading I need to catch up on.) As a result, the several draft posts I have simmering will have to wait until I have either a spare moment or two later in the week, or another bout of insomnia. I will do my best, as usual, but the life of a full-time teaching professor isn’t always compatible with the life of a blogger!
