Dramatis persona*

helenhead Helen Chick

I've always wanted a bumper sticker that said "I'm a female, LDS/Mormon, Scout leading, geocaching, piano-playing, bicycling, mathematics educator with a PhD in maths ... and I VOTE"!

I think this makes me a minority group of cardinality 1!

* Since there's only one of me and "personae" is plural (I think), I've gone with dramatis persona.

Hot spots for the second law of thermodynamics

Entropy is basically a measure of how disordered something is, and the second law of thermodynamics basically says that in a closed environment (without the addition of extra energy … such as hard work) entropy increases or, at “best”, remains the same.

In short: things get messier.

There are some notable hot spots where the second law of thermodynamics seems to be enforced particularly rigorously. These include

  • My office (I make a start to clean it up; a day or two later it seems to be worse than before I tried to tidy), and
  • Garages (in general, and mine in particular), and
  • Scout halls (I looked around ours tonight, after we’d done some organising for a forthcoming camp, and I could see bits and pieces that were out of place, and I couldn’t see the bits and pieces that we’d lost, and I could see other odds and ends that needed repairing or replacing or throwing out. This is what happens when you let Scouts near Scout stuff! Oh, and leaders, too).

Yes, the Scout hall will be a major contributor to the heat death of the universe.
