There's an artistic sensibility there that one cannot help but admire

I just spent way too long trying come up with a joke combining "p-adic" with "Paddington Bear" and completely failed, so I decided instead to tell a self-deprecating story about how long I spent working on the joke.

Yeah, they've been busy:

I would someday like to see an undergraduate analysis textbook that uses both the Caratheodory derivative and the Henstock-Kurzweil integral. There was one book that used the latter by Depree and Swartz but I think it is out of print.

The only thing I have seen is D.J. Bernstein's notes:

Proven: strange patterns in the prime numbers that require chaos to understand. And a way to beat a 200 year old prime-hypothesis. My latest for Scientific American!

A cissoid is just a cis person with more than one object

Do we? I don't think I've used that word in the plural.

I can raise my right one but not my left one. I have no idea what that means. :)

Although not conclusive, there are some reasons to raise an eyebrow here.

Heh! Did Dwork use the same examples?

skircle versus skycle

Image generated by skircle.me consisting of the avatars of those with whom I have had some interaction. It has some overlap with the skycle version, but they are not identical.

After years of having students not understand me, I gave up sometime around the mid 2000s and just say "x zero".

However, I refuse to compromise about the ∞ symbol, which I refer to in class as "lazy eight". :)

the capsaicin of nonassociativity

The saltiness of analysis, the sweetness of algebra, the umami of algebraic geometry, the bitterness of contradictions, the sourness of dead ends …

I'd be curious to taste mathematics.

Dimension of what, exactly? Solution spaces of many linear PDEs are already infinite dimensional.

Just now looking over a worksheet I created a few years ago, I found a sentence I am surprised I haven't re-used:

"Your grade will depend on the journey, not the destination."

Me: It is common to use first person plural, "we", in mathematical writing. It suggests the author and the reader are working together through the mathematics.

Students: *skeptical looks*

Me: Alternatively, it's the royal we as in "We are not amused"

S: *enthusiastic nodding*

Sincerest condolences for your loss, Joe

I hope someday people refer to "Kinyon's Third Theorem" and can describe it easily, but the reason no can remember what the First or Second Theorem were is that they never existed.

I'm wondering if my life isn't an idle game after all.

I guess I could click once or twice and see what happens.

You'd have to ask user Roland Longbow who made that particular edit on 14 September 2022.

Michael Kinyon @profkinyon.bsky.social · 11d

I don't know what possessed me to post that
