In case anyone noticed, I have been a little more absent than usual lately. Call it the last minute push to get ready for the semester, teaching courses I have taught before but with materials that were brand new to me. Then imagine, the day before classes are to start, discovering you have to scrap most of that and start all over again. That has been the story of the last couple weeks of my life.
I will be back once I am more than a couple days ahead of the students!
