Oh, I was just superficially riffing on smells and bookstores.

But I think your dates are probably right: Stoppard's Arcardia being 93 while it's still cool, with Ashton Kutcher in Butterfly Effect in 04 surely a sign it's oversaturated and played out.

"smell of a Starbucks inside a Barnes and Noble" this is still my trips to see my folks in Fargo. Feels like late 90s to me. 91 might be closer to the 80s "mall foodcourt from inside a Waldenbooks" smell

I'm no expert but similarly it's striking to talk about ex-GIs and their experience in the war in this "maybe this caused it" way, but not talk about the GI bill. Society making education and culture a priority.

Transphobia from Mumsnet is exactly where I've personally witnessed the internet radicalising someone close to me.

Huh! Hadn't thought about this before. Does it come up subtly in thermodynamics...(Trying to think where I know logs).

Though I think you want to weaken nonlinear to like, not weighted homogenous. 1/2mv^2 is fine.

Ahhh, I think I left out "classification". There's definitely interesting things otherwise.

They're good groups, Bront.

Isn't it required to at least mention it and give them the link?

Strikes me that it's good training not to be "that guy".

I seem to remember that before they got a math consultant on her speciality was going to be the theory of finite *abelian* groups.

After the Gentle Poet Kobayashi Issa Blossoms at night, like people moved by music Napped half the day; no one punished me! Don’t worry, spiders, I keep house casually.

Napped half the day;
no one
punished me!

Yeah, someone living in a big city is more likely to walk. It's suburban sprawl where all you do is walk to and from car that's going to get you.

But the point about cafe worker makes sense -- any job where you're on your feet much at all I'd think you'd get the steps.

It can work the other way as well -- movement making it easier to talk and let things out. I've had very deep and cathartic conversations on groups runs with people I didn't know particularly well.

I have a daughter of a certain age, pretty sure I know it all. Not a huge karaoke fan but I might need to test this.

Also: not many songs mention fractals, so.

In a square the blue and the green line are perpendicular each other. Find the ratio of the area of the yellow square and the red square.

looool sorry.

Yeah, picking the right framework/viewpoint is important, and people aren't always good at it.

Been thinking about this at a lower level with linear algebra, where algebraic manipulations of determinants and Gaussian elimination gets taught, but geometry makes things clearer.

I don't know. Complex/Lattice is certainly how I think about it. But over Q the structure is so different; people talking about this are interested in things like the rank of E and viewing it as a torus feels the opposite of helpful for that, at least to me.

Also curious!

(I taught myself to cross my sevens and zs to make them more distinguishable. I need to teach myself to not put loops on my 2s so they don't look like alphas or gammas but I'm failing at this one).

Here we go. Same management consultants ruining our universities one by one.

I have never drawn much, but have had thoughts along these lines that make it attractive. If I had infinite time.

People talk a lot about writing being a way of thinking; I see less about drawing being a way of seeing, but that might just be the conversations I'm in and the reading I do.

This week’s horror is our introductory module, which examines the literature, art, music, dialect, film and TV from the region 1500-2025 being forcibly replaced by an entire ‘success in HE’ module featuring two weeks on how to use AI.

I designed my module to incorporate proper study skills…

My favorite bit of I94 in North Dakota is the flat as a pancake continental divide. Bismarck is on the Missouri river which flows I to the Mississippi and down to the Gulf of Mexico; Fargo is on the Red River which flows North into Hudson Bay. But it's just great plain between them.

I clicked through to the HEPI report. It's amazing the disconnect between the headline claim ("public patience with universities is thin as populist sentiment rises") and the content of the report ("the data tell a curious[!] story... most people still like the idea of universities")

I've been thinking about this a lot as I wrestle with my attitude towards all the "skills development" and career prep that is becoming a larger part of my job.

I want to help my students. It's part of the job. But I can't help but feel it distracts from what's really valuable about it all.

inside you are two wolves

One worries incessantly about your job security.

The other wants to rage-quit every time you get an email.

Has anyone written a review of the restructuring going on across UK HE? Trying to understand what is common across institutions: large, team-taught courses, centralised workload models, limited to no research time, promotion directly tied to grant income. How many consultancy firms are pushing this?

Mathematical ‘Urban Legends’ One particular topic at mathoverflow.net has accumulated a large series of incredible stories. While many of them might not be true, they are fantastic. So I thought I would share some of them.

There's also a notion of "blowing up" in Algebraic Geometry, and you get phrases like "blowing up a point of the plane"

Hmmm...guess the two parts don't need to be connected, but I need to sit down and think a little more carefully about cut as being edges vs. partition of vertices.
