The stratosphere is my favorite. I teach stats & math at Fitchburg State University. Arospec, she/her. Methodist. Texan/Oklahoman in the Northeast. Many sports, dance, books, roller coasters.

anyway this plus a lot of NYCB performances are probably part of why I sometimes get confused that so few skaters used non-Firebird Stravinsky (there are so many cool options!)

but then I remember that it is rhythmically... difficult

Saw Boston Ballet dance Elo's Rite of Spring last night, and it's weird to remember now that in grad school I (mostly unintentionally) saw five different choreographies of RoS in under two years.

Between incoming weather and spring break next week, classes were on the sparse and low energy side today. But we cleaned a dataset in PoDA!

Started talking about age-period-cohort effects with my independent study student.

(very) Paraphrased comment from him: "The good thing about a lot of stats people is they make graphs all the time, so their explanations have visuals that are usually helpful."

Lol did I say end of the chaos day? This was before some snow and freezing rain on an untreated road adventures.

ended the chaos day by getting my eCOTS & Beyond submission in, which was nice

(am not thrilled about this year's theme, but the prompt is pretty wide!)

#MathsToday My prep for classes today was pretty rushed, so things feeling bad/flat very much feels like I set them up poorly.

Did have several students successfully making small fixes to skill quizzes, though! And a chat w/ a stu about baseball in which she gave me grief for being an Astros fan. πŸ˜…

Four Colors and Teaching Mathematics What the Four Color Theorem and its history tells us about the role of humans and proof in mathematics education.

I wrote about the story of the Four Color Theorem that I remember being told and Terence Tao and generative AI and some of my thoughts on teaching.

Threw away part of a plan in Stat Analysis after a student comment, drew a picture of mean squared error instead. Tried to get to a picture of R^2 but didn't quite. Not sure it was a good idea broadly speaking? But we aren't coming back to this until after break, so maybe all right.

Libs complaining about β€œseparation of church and state” re:Adam Hamilton’s potential senate run are really showing their asses.

The FAQ from CoR is *thorough*. For just "considering," it's all a lot.

We only talked about base ten in class, but I had given a prompt on the homework to look at other versions if they had time/interest. (Same with the tent map -- we looked at mu = 2, but I had suggested trying others.)

#MathsToday In Math of Climate, we looked at the decimal shift map and the tent map, and then we started reading "Period 3 Implies Chaos."

It's a big lift for this course, but I think it's doable and important, both content-wise and in terms of practicing reading a math paper.

#MathsToday: Data wrangling today in PoDA, headed quickly towards cleaning! (Just joins left first.)

Cleared up some things with intervals in Applied Stats (though a typo did not help 😬) but will need some more practice with interpretation next week. Snow days have been rough for this course.

To the second point there: this was an activity that involved writing some R code, and it was interesting to see students pull out hard copies of in-class activities (only sometimes included code) as opposed to going to the complementary Quarto files.

Problems:
-not enough practice with relevant skills (most useful HW is due tonight)
-had not practiced efficient methods of finding examples (excited to see stus pull out resources, but weren't always the best ones)
-provided too little team structure (teams that really worked together had success)

#MathsToday completely underestimated the amount of time an activity/assignment would take in Stat Analysis, which will be fine but is not exactly what I was hoping for after losing Monday to snow πŸ™ƒ

just going to keep getting a little emotional about this off and on for a few days, on rotation with feelings about Riku and Ryu, Amber, Alysa, and Kaori

Really happy for Canada and Team Homan. They are now Olympic medalists, and I’m glad they’re happy too

Also happy for Tabitha Peterson! They were fourth. Last year they were ***12th***

I don't really feel like I'm doing justice to this material, though, and it's a little frustrating.

#MathsToday Math of Climate: cobweb diagrams! Comparing the maps 3x_n - x_n^3 vs 0.5*(3x_n - x_n^3)! Chaos enters the picture and things go in all the directions (but in only one dimension). A student noticed topological transitivity totally unprompted, which was my favorite part.
