I forget the exact video, but there are some interesting presentations on YouTube from engineers re the Laplace transform. There's this qualitative analysis they do in phase space without reversing the transform. Very different from the usual DE presentation.

Anyone else reading the new China Mieville book (The Rouse)? I just finished the first section and I'm really liking it so far. It has really beautiful writing and strong empathy for flawed characters.

Maybe "order doesn't matter" really does apply to both? Associativity = "order (of computation) doesn't matter" Commutativity = "order (of inputs) doesn't matter"

I watched A Woman Under the Influence last night. What a great/intense movie. A really interesting exploration of mental health in the context of patriarchy and traditional family structures.

I'm trying Hades again. I'm a little frustrated because I've full cleared silksong and hollow knight (including optional bosses), but I really struggle to stay alive in Hades. Some combination of my impatience and hard to parse graphics probably.

I don't see a bright democratized future with lower barriers to access. I see a future where you have to pay to play and where already overworked reviewers have to contend with a flood of convincing math slop (the crank problem x 100).

Do we really believe tech companies are interested in pure math? Do these mathematicians know the agendas of the companies they are shilling for?

Jared Holshouser @jaredholshouser.bsky.social · 02/08/2026

It's genuinely upsetting to see high level mathematicians be so un credulous at the motives of big tech. No ethical thoughts at all, seemingly. Just oh look this shiny toy they were "nice" enough to give me spat out a theorem.

If you can get access to the book Crest of the Peacock, you'll have lots of non-European locations. Also the book Maps of Knowledge. Unfortunately I don't remember specifics off the top of my head.

One of my remaining bits of snobbiness is I judge people if they only read one genre. I know it's not fair of me, and people read for different reasons, but I can't imagine actively seeking out the tropes that I want to read ahead of time.

I wish I did. My instinct is it's pretty weak but that's all I can say.

You could choose a nonstandard infinite natural N and consider the rays at angle 2pik/N, where k ranges over the N*. For each ray take the coordinate that is distance 1 from the origin. Make the nonstandard polygon with these vertices. Then collect the reals that are near the polygon.

It was fun to figure out how to topologize the ordered compact subsets and the resulting spaces have some really interesting properties.

I've got a new paper that I'm proud of: arxiv.org/abs/2507.17936. While teaching discrete math, we got some results about the topology of finite subsets, finite tuples, and compact subsets of a given space. I was teaching combinatorics, so I wondered about ordered compact subsets. This is the result

An Adaptation of the Vietoris Topology for Ordered Compact Sets

We introduce a natural topology on powers of a space that is inspired by the Vietoris topology on compact subsets. We then place this topology in context with other product topologies; specifically, w...

I can see why you were frustrated trying to make that. It's a really nice end result though, congrats!

AI companies are just like every other profiteer horning in on public education money. They aren't trying to fool educators, who know better. They're trying to fool politicians, who are stupid af and easily bought.

Everyone's experience is different, but I quit caffeine about a year and a half ago and it really helped my anxiety symptoms. I love coffee but apparently my brain didn't.

Today was my first day at a non academic job since I earned my PhD. Academia turned out to be a corrosive environment for me, but I hope to continue my research as a hobby now. I'm hopeful that I can thrive in my new work environment and also do some good for the world.

This. As educators we can easily get too big of a head and take a student's word that we were the first person to ever show them something. I think it's better to give both the student and their former teacher the benefit of the doubt.

I absolutely loved working on this cover art w/ @statsteph.bsky.social, @ivelasq3.bsky.social, & Rebecca Powell! Fantasy maps + data? What a dream. Learn how to do tidy survey analysis in R 👇 🌟 Free online: tidy-survey-r.github.io/tidy-survey-... 📖 Preorder: www.routledge.com/Exploring-Co...

Cover of a book titled "Exploring Complex Survey Data Analysis Using R" by Stephanie Zimmer, Rebecca Powell, and Isabella Velásquez. Illustration is in the style of a fantasy map, but with data represented throughout the landscape. For example, mountain ridgelines are line charts, buildings create a bar chart, a farmer's fields make up a contingency table, light lightposts are lollipop charts, etc.

Have any of y'all ran a senior seminar/independent study in set theory before? I'm running one this fall with an interested, talented student who lacks any real set theory experience. Any advice you have is appreciated.

In honor of the Chinese remainder theorem, I'm going to refer to Newton's method as the British root approximation theorem from here on out.

It's traditionally a very packed class. Vectors, functions from R to R^3 going up to TNB frames for some reason, functions from R^3 to R with optimization and integrals with change of coordinates, oh and then cover Stokes theorem. It's a mess.

Fortunately, the quality of his writing is pretty good too from what I recall. It's not part of a story, but his note about his friends who died from drug abuse at the start of a scanner darkly really gets me.

Inside of you are two numbers that are transcendental. We know at least one way of combining them is also transcendental. That might be you.

I recently saw an academic post about using it to write a job ad and brag about how it made making a first draft easier. All I could think was did they not have an ad from a previous year they could use as a starting point?
