Will this upcoming winter quarter be the first wherein I actually register for classes ahead of time instead of just showing up the first day of the term?

It was raining again today, which meant that I needed to switch which bag I use to walk around campus.
Unfortunately, Laureline had decided to make it her bed just before I'd started packing up for the day. It crushed me to have to move her to one of the other bags.
Please think of her today.

A thing that I do with the cats is stroke their foreheads with one of my thumbs, often after I've wet it.
Valérian has recently taken to doing the work for me: he wets my fingers himself by licking them and then rubs his forehead against them.

Have you ever wondered where the word "skosh" comes from?
少し (sukoshi), which is Japanese for "a little."
「今日は少し肌寒いですね。」 It's a little chilly today, isn't it?

Donate money to a food bank or food pantry, then give your extra cans and boxes to a mutual aid org, love fridge, free pantry, etc. in your neighborhood.
Money in formal channels takes advantage of scale, and whatever you can spare in informal channels reaches more neighbors.

spoke with the executive director of my local food bank today and got this really incredible line: "if you donate 1 can of green beans, we can give away 1 can of green beans. but if you donate a dollar, we can give away 6 cans of green beans"

I'm working on a review of Karen Hao's "Empire of AI" that basically boils down to this: the thesis is beautiful and well-supported, but Geoffrey Moore might have a thing or two to offer in re crossing chasms. Most lay readers understand linearly, not in terms of the edges and vertices of a graph.

Another possible bit of assigned reading in rhetoric this quarter was Ethan Mollick's "Co-Intelligence," and a striking number of responses on Canvas can be summed up as: This borders on hagiography.

It's nice that there's an open source slider gadget for visualizing this now, but it has many years before it catches up with Mathematica. (Though, man, I really wish that were today already.)

I've sufficiently trolled the prof I'm reviewing calc with this quarter.
He asked about the parametrization of an osculating circle at a given point on a smooth curve, I had one at the ready, and I have him now strongly considering joining my reading of do Carmo next quarter.

It looks like I'll be covering the first three chapters over eleven weeks and then working toward Gauss-Bonnet the next eleven weeks.
I may see if we can go more in-depth with the covariant derivative and touch on why modern diffgeo tends to be coordinate-free.

I might be doing a reading of (baby) do Carmo next quarter since he only requires multivariate calculus and some of the vector analysis that comes along with it.
I just fear that I'll lose people when we get to the first and second fundamental forms, but we'll see.

I hate to admit that the Look Around You episode on maths helped me develop and assert a core belief:
You absolutely should have a tool roll for your pencils, pens, markers, chalk, and erasers.
You can dispense with the Garry gum though.

I guess it goes to show how little we actually covered in diffgeo when I took it. We got to Gauss-Bonnet, sure, but we left off with the classical presentation of Mainardi-Codazzi and didn't bother absorbing the Christoffel symbols into the covariant derivative.

I somehow never took a college-level rhetoric sequence my first go-around at this whole undergrad thing, so part of this quarter is dedicated to fixing that.
Karen Hao's "Empire of AI" is assigned reading, and the dramatis personae is basically a who's-who of folks who have me blocked on Twitter.

I love breaking folks' brains when I go on about how vectors don't necessarily need a magnitude or a direction.
If you don't have an inner product, you don't have a notion of direction.
