Quote of the Day: Differential Equations and Star Wars Robots

"You know you're in trouble if the different cases for your differential-equation solutions start sounding like the names of Star Wars robots."

(That is my spontaneous gem from today's lecture. We're doing Frobenius series.)

Alternative Cuss Words

I am highly amused by this pamphlet of alternative cuss words.

Well kiss my grits!

Some of the alternatives (e.g., "cotton pickin" and some others) that are considered ok in this crib sheet are actually really bad if one thinks about them. And some of the ones to "handle with care" seem just fine to me. Also, I'm not sure what game-show hosts like Alex Trebek, Pat Sajak, and Bob Saget have to do with any of this.

Update: Steve Van Hooser pointed out "son of a motherless goat" as a particularly good one. Indeed it is, and I fondly remember its use in the show Perfect Strangers.

"The Interested Reader"

I love how many mathematics papers refer "the interested reader" to various sources for more information.

It is a little-known—but not terribly surprising—fact that most mathematics papers have only a single reader, who may or may not actually be interested in further discussion.

An Ancient Roman Dice Tower

It would be awesome to whip out one of these — ideally, along with an ancient d20 — during a Dungeons & Dragons game.

Dame Frances Kirwan Named "Savilian Professor" at University of Oxford!

Here is some really big news: "Dame Frances Kirwan has been elected to the Savilian Professorship at the University of Oxford. Frances will be the 20th holder of the Savilian Chair (founded in 1619), and is the first woman to be elected to any of the historic chairs in mathematics."

This is a very big deal. (See the Wikipedia entry for a discussion of this professorship.)

I know Frances. (We were colleagues in the Mathematical Institute at University of Oxford, of course) She is awesome (both as a mathematician and as a person).

Frances is somebody who is well-known within mathematics but pretty much unheard of outside mathematics.

Headline: "Massive Wave of Butterflies Lights Up Denver Weather Radar"

How very chaotic. :)

At least the radar wasn't jammed.
