So last week there were only a handful of comic strips which mentioned mathematics in any detail. That is, that brought up some point that I could go on about for a paragraph or so. There were more that had some marginal mathematics content. I gather them here for the interested.

Gordon Bess’s **Redeye** rerun for the 7th mentions mathematics as the homework that the chief is helping his son with. It could be any subject, but arithmetic is easy to fit into one panel of comic strip. And it’s also easy to establish that the work is on a low level. The comic originally ran the 18th of February, 1973.

Bob Shannon’s **Tough Town** for the 7th has an appearance by a Rubik’s Cube. I’m always going on about that as a group theory artifact.

**Tough Town** on the 9th also mentioned algebra as a tough subject for students.

John Allen’s **Nest Heads** for the 10th mentions sudoku. Also the trouble with accounting.

John McPherson’s **Close to Home** for the 11th mentions percentages. The joke’s built on doing a meaningless calculation. And a bit of convention, in which the label has been reduced to the point people could mis-read it. You just know this guy would tell the “scanner didn’t pick it up, it must be free” joke if he thought of it that fast.

Paige Braddock’s **Jane’s World** for the 11th is part of a sequence from 2002 in which Jane concludes the problems in her life came from the introduction of algebra. Her niece is having fun with algebra, a thing I understand. Algebra can be a more playful, explorative kind of mathematics than you get with, like, long division. For some people it’s liberating. This one’s a new tag, so I’m sure to be surprised that I have ever mentioned **Jane’s World** sometime in the future.

Wiley Miller’s **Non Sequitur** for the 11th presents a Sphere of Serenity. Or, as Danae’s horse points out, a Cube of Serenity. There are ways that the difference between a sphere and a cube becomes nothing. If the cube and the sphere have infinitely great extent, for example, then there’s no observable difference between the shapes. Or if we use certain definitions of distance then the sphere — as in, the points all an equal distance from a center — can be indistinguishable from a cube. That’s not what the comic is going for.

There were no comic strips with any mathematical content last Saturday, it turns out. There have already been a couple comic strips I think I can discuss. One comic strip, anyway. I should have my essay about it for eager readers on Sunday. Thanks for your patience.
