Participating or Protesting, Always a Nerd

    This week is "Spirit Week" at the High School.  It is a week designed to promote the kinds of things about high school that I avoided like the plague when I was a student:  School Spirit, Class Consciousness, School Colors, Decorating the hallways, pep rallies, etc. (As an adult my feelings may or may not have evolved, depending on the actual activity and my degree of snarkiness that day)

    Today is "Wear your favorite sports jersey to school" day. I, of course, own no such gear.  But Irene reminded me of one of my favorite nerd shirts:

Cardinal numbers are a generalization of the natural numbers used to measure the size of sets. The cardinality of a finite set is a natural number: the number of elements in the set. The transfinite cardinal numbers describe the sizes of infinite sets.

Aleph null is the smallest infinite number. It is the cardinality of the set of natural numbers.

Neither has anything to so with sports so far as I know (but then again I wouldn't know, would I?)

 

So, today I am walking around in this T shirt which I am predicting very few people will ask me any questions about.
