I've been SUPER busy this month what with:
i) faculty job interviews at a couple places,
ii) a bad cold, thankfully now over,
iii) a minicourse I'm currently teaching at the University of Maryland.

Note: the cartoon has nothing to do with the equation above (or the sentence partially displayed below). But feel free to try to figure out what the equation means, if you can!
