Me: In this problem, if you're not sure what properties of the integers you're allowed to assume, just ask me.

Student: Can I assume Fermat's Last Theorem?

Me: Is that going to help you in some way?

S: Well, no, I just wondered if I can assume it anyway.

Me: 🙄

Oooooh, the tunnel song, yes, of course, I was being stupid.

Wait, which song is the creepy one?

See the excellent answer by GEdgar:

Are the elements of a module also called vectors?

Are the elements of a module also called vectors? Or if someone says 'vector', are they talking only about a vector space? If no context is given, are there some standard assumptions?

I just learned a little bit about iatromathematics and now I feel like I should lie down for a little while.

@timhenke.bsky.social How's your ã? One of my closest friends is a João and it took me a lot of practice to get his name right.

I lived in South Bend for 14 years and even though I drove to Valparaiso a handful of times, I never made it as far as Hebron, so I never saw the famous sign. Ah well.

Maybe my students will pay more attention if I have my class autotuned

I recommend Smooth McGroove's videos if you haven't seen any. A capella renditions of video game music, including percussion and with no autotuning.

Every time I teach integral calculus, I forget one of Wolfram Alpha's defaults:
∫1/√(1-x2)dx = arctan(x/√(1-x2)) + C
instead of
arcsin(x) + C

Invariably someone asks why it does that, I reply I don't know, write a note to myself to find out, and then...

Repeat the next time I teach the class

As a superdeterminist, I would tell you my take, but it's been determined that I'm not going to.

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.

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!
