Today I learned that John Milnor wrote a limerick in which Christos Dimitriou Papakyriakopoulos's name spans three lines!

Today is the day I discovered DONUTS, the Database of Original & Non-Theoretical Uses of Topology: https://donut.topology.rocks/

I'm looking to crowdsource some knowledge about current hiring practices in university math departments. To that end, do you recall the dates for application deadline, first round interviews, and campus interviews of your most recent tenure track search?

Feel free to email your response if you prefer: ormsbyk@reed.edu. Thanks!

NASA and the Biden administration could waste a lot of taxpayer money putting atomic clocks on the Moon OR they could appoint me Lunar Time Czar and I would tell them what time it is on the Moon for a very reasonable fee. https://www.reuters.com/science/white-house-directs-nasa-create-time-standard-moon-2024-04-02/

Just in awe of the “Invisible Things” art display at my kid’s school.

Tired. Bored. Worry. The Slepy.

Me too, kid. Me too.

Workshopping titles for my lecture notes on TDA. What do folks think of "Nevertheless, cycles persisted: an introduction to topological data analysis"?

I love imagining the mathematical needs of whoever decided on the unicode math characters.

"Gosh, I'm just always needing notation for when two lines are sorta-but-not-completely perpendicular. I know! ⫡"

"What if something's not just bigger than or much bigger than but WAY FUCKING BIGGER THAN? Aha: ⫸"

"I'm doing so many specialized contour integrals and hate writing with words so much that I'm going to invent a specific symbol for line integration with rectangular path around a pole: ⨒"

"I don't know whether A is a subset of B or B is a subset of A, but at least one of those statements is true, so... A ⫓ B."

"Gosh, I have this element S of the Picard group of a symmetric monoidal category and I want to tensor M with the tensor-inverse of S but don't want to create notation for the tensor inverse. As such, consider M⨸S."

Actually I get all of my math jokes from church signs.

Can someone who knows physics tell me how vector potentials (solutions A to F = curl(A)) are related to gauge theory (at least at the level of electromagnetism)? Wikipedia starts talking about 'suppressing unphysical degrees of freedom' and that just seems wild.

Me: I'd like to see a computation.
Algebraic Topologist: We have computations at home.
The computation at home:

Don’t know who needs to hear this, but: trigonometry = trigon-ometry = measuring trigons (aka triangles). 🤯📐🧮

OEIS may be the only nonempty encyclopedia containing 0% of the subject matter it purports to cover.

At the Serious recreational mathematics session at the joint mathematics meeting. Persi Diaconis’ train is stuck on the way to San Francisco so Erik Demaine is “improvising”, talking about curved origami.

Anyone have a pdf of Boardman's Homotopy structures and the language of trees? I can dig it out of the library on Monday, but I'm a very impatient person.

What are the applicant's chief weaknesses or areas of growth? That would be their lack of access to a cutting edge graduate program that only you can provide!

Serious question for folks involved in formalization projects, especially in Lean: How do we know we can trust all the definitions in mathlib? Couldn't one little mistake make large classes of objects impossible/empty? And last time I checked, universal statements about empty classes are easy to prove but of limited interest.

Whoa. Is Cornell the only math program not accepting PhD students this year, or are there others as well?

Becoming mildly obsessed. Please send help.

I'm trying to help a wildly talented student who wants to go to math grad school but didn't quiiiite finish their undergrad degree. Anyone have experience with grad admissions committees and know if this is in the realm of possibility?

What are LaTeX/BibTeX users doing for bibliography management these days? My 'system' involves time-consuming copy-pasting between old .bib files + using MathSciNet to generate entries for published material, and I'd like to do better.
