#MathsToday Solid retention of confidence interval ideas from Tuesday in Applied Stats, some needed notation review, and some more work with hypothesis testing that I think helped!

#MathsToday some good observations from students about different kinds of chi-square tests!

#MathsToday We inducted six students into Pi Mu Epsilon today and gave four students departmental awards. Celebrating all of these incredible students and their mathematical achievements was the best.

Harold E. Brooks received the 2026 AMS Robert H. & Joanne Simpson Mentorship Award for guiding generations of atmospheric scientists. In this Award Spotlight, he reflects on mentorship, severe storms research, and making forecasts meaningful. Read the full conversation here: https://bit.ly/4cmCWH1

Definitely my most historical-heavy Queer Romance roundup for @smartbitches.bsky.social so far! smartbitchestrashybooks.com/2026/04/apri...

#MathsToday Two students came to office hours thinking they were very stuck on some data cleaning, and together we figured it out in about 10 minutes! (And now I know what the trouble spot on this assignment is.)

some very good drama in the two gymnastics regional finals today

In Easter Season, add Alleluia, alleluia, alleluia.

#EasterSkies Day 1, after sunrise service

😭

Clemson *so* close to advancing to nationals, just short of Stanford at the end. They should be really, really proud of what this program has done in so little time.

Almost 150 entries from students in 30 US states, 2 Canadian provinces, and 5 other countries! It was a pleasure and privilege to organize this contest. Go read the winning essays and learn about some very cool people and very cool ways to use math on the job. #MathSky

#MathsToday not-quite-panicked skimming of @mktippett.bsky.social's book before Math of Climate to figure out what I should say about time series and spectra in ~40 minutes of class, but it went well! Didn't do a ton, but good conversations looking at the MJO and then talking about AR models.

#MathsToday: Great day in Applied Stats doing inference for means! Oreo activity and a card sort with different hypothesis setups. And a reminder for me that clear expectations and matter-of-fact-ness help a lot in classrooms running well.

My Red Sox fan student, looking kind of annoyed today: "Did you watch the series?" "I enjoyed it very much!" "I bet you did."

#MathsToday Started reading and discussing a paper about age-period-cohort effects with an independent study student. Did not have enough planned for confidence interval day in Stat Analysis 🙃

#MathsToday sandwiches day in Principles of Data Analysis, and also got to share the corresponding PRIMUS article with coauthors in a "how are we structuring our paper?" conversation

#MathsToday some good regression thinking in Stat Analysis, along with opportunities to clear up confusions.

when the pastor says he'd like to talk to you, gives no indication about what beyond "it's an invitation," and sets a date for almost two weeks from now (understandably, given Holy Week, but...)

YUMA clean Turandot!!!

Skating Queen. 😭😭 Skating will not be the same without her. I’m so grateful for what she’s done to this sport, in her athleticism, her artistry, her leadership, her sportsmanship, her attitude, her seriousness and her levity. I hope she brings all that to the students she coaches. 😭

turns out, you get worse at things when you don't practice them (I accidentally didn't drive for three weeks, whoops)

#MathsToday Running our math contest's solution session is always fun chaos, and in Math of Climate we finished (at long last) the Period 3 Implies Chaos proof! now I just need to write a homework introducing climate indices 😬

Thank you, Kaori Sakamoto. It's been a privilege to watch you skate ⛸️🥹😭🥰💖 #WorldFigure

🥇🥇🥇🥇 That's our queen! 😭

Kaori spelling K A O R I as she walked out 😭

LIA TRENNT MEDAL AHHHH! #WorldFigure

#MathsToday 1) Helpful feedback from students on a colleague's new activity in Principles of Data Analysis 2) Applied Stats ran short for the first time since I switched to strands 3) A student who had solved the problem of the week asked about my offhand mention of doing it with linear algebra

tonight was not the night I would have chosen to watch a Worlds number of short programs in a couple hours, but here we are, thanks Peacock

#MathsToday IRB proposal edits in independent study, hypothesis tests of two independent means (in other words: Double Stuf vs Regular Oreos) with Stat Analysis!

just realized that May 10th will be my 7th time preaching and yet, somehow, my 3rd time preaching on Mother's Day

#MathsToday Started modeling in Principles of Data Analysis -- the students clustered research questions then reclassified them after talking about supervised, unsupervised, and reinforcement learning Calculating confidence intervals in Applied Stats after a while of working with them conceptually!

#MathsToday really rough day in both classes, and a research talk that didn't feel great either. Had a few good atudent conversations outside of class, though, about dynamical systems, a couple problems of the week, and the data analytics minor.

Ashton's Dream has stronger storytelling by Balanchine's by *so* much. I always forget how dramatic the difference is.

#MathsToday A thing I said to Math of Climate students today: "Sometimes people think that reading is reading. But for math papers, reading isn't just reading..." A day of lots of drawing pictures, working through notation, and writing longer versions of the proofs!

Novruz bayramınız mübarək! 🌸

#MathsToday Felt like I mismanaged time on the hypothesis testing portion of stats today, but correlation coefficient and observational study vs experiment went pretty well!

Listening to my grandfather talk about genealogy and family stories is like getting 180 years of gossip all at once

I am literally at an NCAR-hosted, NCAR-led meeting where the future of U. S. radar meteorology - one of our most lifesaving enterprises - is being articulated by 180+ diverse participants. NSF NCAR is the only institution capable of convening our community so effectively.

Eating some chilaquiles now and look, salsa verde is one of the great human achievements.

Today in the 3-4 page game of the brier playoffs will be the 69th and final time Brad Gushue curls against Brad Jacobs (Gushue has won the all time Braddle 35-33)

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.

#MathsToday 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!

#MathsToday 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. 😅

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. www.peter-keep.com/2026-03-02-f...

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. #MathsToday
