I met a fellow math professor at a conference several weeks ago who is teaching a class on the idea of infinity. He told me of a story he tells his class about how difficult the idea of "infinity" can be. He described a class that a student wants to sign up for with an infinite number of seats. There are, however, already an infinite number of students enrolled, so each seat is already taken. A new student comes into that class, and wants to enroll, only to find every seat taken.

For my husband and myself, our Thanksgiving weekend was pretty low-key. Turkey at our friends’ house (we only had to cook side dishes!), catch-up on work (our computers are forever on), some yard work, neighborhood walks, a family board game. For my 6th grade daughter, there was a school project. The project was to build a totem pole to represent her family. Guidelines: no more than 5 inches diameter; 12-24 inches high; needs to be stable; use more than two different kinds of materials (clay, wood, cereal boxes, pipe cleaners); “Think outside the box”.
