I especially liked Des' remark about telling Boole about the AI mess but getting no reply.

George Boole died on this day in 1864. en.wikipedia.org/wiki/George_...

His biographer Des MacHale left these flowers at his grave today. en.wikipedia.org/wiki/Des_Mac...

I was the shadow of the waxwing slain
By the false azure in the windowpane

I feel the same way. I am a Michael, not a Mike.

Every day I am thankful that all it takes to verify my humanity is my ability to check a box.

Wow, I complete forgot about that "Irish name, Irish name, German/Yiddish name" gag. I had to remind myself how the whole episode goes.

Honestly, I wouldn't hold back.

I much prefer being mistaken over being incorrect, and I prefer being incorrect over being wrong.

On the other hand, if I'm right, I'm right.

The rain in Maine falls mainly on my mane.

Interestingly, Gibbs, in his 1881 "Elements of Vector Analysis" book (more like a pamphlet), just used the math typeface of his day for i,j,k.

An interesting historical question: when did the use boldface for vectors became common? I don't know the answer.

Yeah, I haven't seen complex exponentials being taught in calculus or below since the early 90's. They and the hyperbolic trig functions usually don't show up until differential equations courses.

They were optional for a few years when I was just starting. But no one had time for them.

I guess it's one of the green ones. I wish they'd have narrowed it down further.

Same, I just doodle a right triangle and go from there. I've never taught hyperbolic trig functions in calculus classes.

Typical instructions for algebra exercises:

"Simplify the following expressions. Assume that all variables are positive."

That second sentence is so important, and so often ignored or forgotten.

(Context: I just graded exams and every student simplified sqrt(x^2) to x instead of |x|.)

Abstract. I think this idea will work.

I hope my coauthor shares my optimism.

At one of those "clarity vs elegance" junctures in my writing of this paper. I'm greedy though, so I hope I'll figure out how to have both.

Well, it's the usual thing: automatic payment after the trial period unless you explicitly cancel. But the way I worded my question was pretty silly. :)

While considering a purchase, I asked "how much does the free trial cost?" so now I have to walk from Denver into the Pacific Ocean.

Now I have the Monty Python "Universe" song stuck in my head

I like rococo artwork in 25 minute intervals, each followed by a 5 minute break.

That is, I like pomodoro rococo.

To every map
in kern, in kern, in kern

Reading a paper that denotes the kernel of a mapping f by
"ker f" but the kernel of a mapping n is denoted by "kern".

K: Have you considered consulting a doctor about that?

Me: I am a doctor. I have a PhD in mathematics

K: No, I meant

Me: and therefore I am an expert in all scientific disciplines

Heck, he could tuck a cello under his chin

I think it's the *only* time I like to use the radical symbol.
