Not The Course I Expected...

It looks like I'll be teaching this summer after all - a five-week compressed section of Differential Equations I. The person who was supposed to teach it will not be able to, and the Assistant Chair wasn't able to find anyone even remotely willing to take it on but me.

The course begins on July 8, so next week I'll have to go in, get the textbook, and start prepping. (I'll be teaching a normal section of the course this fall, so I was going to have to do this at some point anyway.)

Suspenders & Belt?

Every month, I buy a local pass from the county transit agency. They send it to me promptly - maybe two days between order and delivery - in a nice custom envelope, with their logo and everything on it.

It is always taped shut. One would think that, in custom ordering envelopes, they would make sure that the glue was of good quality as well. Why the tape, then?

My only guess is that it's easier to open an envelope, remove the pass, and reseal the envelope undetectably, if glue is the only seal. It still seems odd to me.
