My first PhD student’s thesis was related to this topic. If we ever cross paths in real life, I would be happy to tell you all about it. Couple years ago I wrote an internal grant proposal judged by broad audiences titled “can one hear the shape of a donut?” They loved it.

The National Science Foundation has indicated that, as of February 4, 2026, they are not yet prepared to announce their fellowship recipients. While the NSF stated that results might be released in the coming weeks, this delay places both job-seekers and hiring institutions in a difficult position.

Not yet. They promised February 1st. Maybe today?

Behind the disturbing image of ICE snatching a half-naked, elderly Hmong American from his home DHS has claimed without evidence that they were looking for someone else when they took ChongLy Scott Thao.

New — I wrote about ChongLy Scott Thao, the elderly Hmong American wrongly arrested and forced out of his home by ICE in his underwear during the punishing Minnesota winter, what witnesses saw, and DHS's racist claim that he fit the description of another Asian man they were looking for.

A black and white cat is lying on its back in a gray pet bed. Its paws are curled up near its chest. Next to the cat is a metal dish filled with catnip. Is he high or not? That's the question.

guilty or not??

Me: How much rice to fill 16 peppers for dolma?
Google AI: 12 peppers usually take 1 cup of rice. So for 16 peppers, you would need about 3-3.5 cups.

I didn’t know what dilogarithm was until the 3rd year of grad school. Grace Work and I were computing co-volumes of some Veech groups and when I first saw that some integrals resulted in dilogarithm I knew we were cursed. Somehow magically they all cancelled each other out!

I've wanted to write something about academic accommodations for a while, and in the absence of other inspiration, I'm just going to put it here.

I have a few points to make but first a bit of context about me. I'm profoundly deaf in my right ear. Basically can't hear anything in it. 1/

Yes! Put it! Also lol at the second comment.

Three actions of D₄: on itself by multiplication, on itself by conjugation, and on its subgroups by conjugation. Action graphs of each are shown.

This week, I recorded 4 new #VisualAlgebra YouTube videos on group actions. I heavily use the following concepts:

1. G-sets
2. Action graphs
3. Group switchboards
4. Fixed point tables.

Interested? I'll give you a preview here. Please share!
