Emi, resting 😷

Unless you mean you have to actually write down a function. In which case I'm very sorry for your suffering.

Have you considered the algebra student's best friend, the Sylow theorems

I guess when I see my own cookbooks I usually think "oh, right, maybe I'll start doing that again someday" or perhaps I'll think about a recipe in it I wanted to try. But also I usually think of these things as temporarily on hiatus, not permanently abandoned.

*if this isn't true, come on, get a better function.

I would say btw that the identity map from R to R is not the same function as the identity map from (0, \infty) to itself. So for me, domains are very much baked in to the definition of a function. This is probably because I'm an algebraist.

Firm yes, because we'd like "domain" to be meaningful lol.

But you can always* take a smaller domain so it's fine for your example. Eg the identity mapping and 1/x are both defined on (0, \infty) or C without 0 or the strict upper half plane in C or... whatever.

But also no unless your domain is like. Really unusual. Or unless you're defining your function in a really unusual way. So maybe! But probably no.

What do you mean "the" domain

I see y'all out at #JMM2025 without masks and I'm disappointed in you.

Learning should be a communal endeavor almost always imo. I would go to great lengths to find even one (1) pal to be confused with, rather than trying to do it all on my own.

I would do "enough" problems 🥰 i.e. I would work through problems to understand whatever the thing is and then a couple more to test my understanding.

Which is unhelpful for a student with no pedagogy training bc it's hard to evaluate your own work!

But also I think problems assigned vs problems available is very different and students should (usually) do more than is mandatory! So I am pro 72 problems in textbook.

Depends on what the problems are for, I think. Like the problems I provide for an in-class introduction to a topic are way more granular and hand-holdy than homework.

But I would always rather carefully evaluate a few problems done thoroughly than a lot of problems done sloppily or by rote.

2 seats still open in this one-shot!

Yes, we have critical mass—we are, confirmed, definitely playing on Sunday!

It's even better than that—it's $10 for you and $10 for another player, who will probably use it on more sessions with me, lol. So, in a way, $20 for me!

Omg yes just saw! Very exciting!

Play Dungeons & Dragons 5e Online | Palace of the Snow Queen | Festive! | LGBTQ+/Newbie Friendly 🌈 It's the winter solstice, and your party is celebrating the longest night of the year with the rest of the town. It's all fun and games and spiced cider...until the Snow Queen, an archfey of legend, k...

Poking my head back in to advertise...a beginner-friendly festive one-shot, this Sunday afternoon!

This is my last one-shot of the year, featuring talking animals, a mysterious ice palace, and a quest to save a friend. Expect whimsy and lots of roleplay.

This sounds so fun—and recruiting other players is THE easiest way to make sure there's enough people to play!

(But before anybody actually makes a StartPlaying account, let me know, because I've got referral codes for $10 off your first session.)

So if your wife has specific date/time requests...let me know and I'll see if I can make them happen!

I could! I generally schedule one-shots by 1) player request, or 2) my own scheduling preferences, in that order.

A one-shot with one guaranteed player is quite likely to meet its minimum and actually happen. E.g. the 29th date was a player request, so I expect that one to fill up.

In addition to professionally Dungeoning and Dragoning, these days I also do independent math tutoring! If you've got students who need help and can afford a private tutor, send them my way. To toot my own horn, I'm very good at it.

Logistics are amazingly not character-limit-friendly—DM if you'd like to talk details?

For gifting purposes, it's also possible to request a custom booking if you're looking for a game not on my usual schedule—and this can be set up so it's "pre-paid", essentially.

So glad you asked—this is def a thing people do!! StartPlaying does have gift cards, which is easiest. Or you could set up an account for your wife and book a session the normal way, which can be cheaper.

(One person can also pay for multiple seats in a single game, if you wanted to try it out.)

Retweets very appreciated, thanks for your support of this exciting professional change, and so forth.

If you're DnD-curious, and/or want to hear about future games, and/or want 50% off the price of this one-shot, shoot me a DM :)

Hi, twitter migrants! I don't often math tweet anymore—instead, you can find me professionally running games of DnD. And YOU could play in them!

I'm running a very fun, very silly, very beginner-friendly one-shot this weekend and next:

Like I'm pretty sure this problem would go away if I, too, was rich and had a lawyer friend I could ask to write a legally threatening little letter back to her. Unfortunately, we live in hell, so.
