It's finally here! "Linear Optimization: A Geometric Inquiry Course" gives an inquiry based course in linear optimization supplemented by technology for intuition building. A great class for interests in either pure or applied math! Physical Copies now on sale: www.619wreath.com/store/p53/Li...

Please encourage people to apply for the MathAndCobb Fund for ME! youtube.com/shorts/5cVgy...

Tired: -X points per unexcused absence Wired: you're adults show up if you want to idgaf lol Inspired: actually I have some ability to help encourage good habits, so you get X no-questions asked absences, after that you meet with me to discuss your progress and fully waive the grade penalty

I created a ChatGPT replacement that is completely private. The downside is that you have to provide both sides of the conversation. radcliffe.dev/mirrorchat/

He wants you to think he's innocent, but did you know this Goomba once used federal award dollars to fund travel to a non-existent conference on Delfino Island? That's right: Professor Frankly committed grant fraud. #AcademicSky #MathSky

Like Monty Hall, a lot of insight comes from taking the situation to an extreme. One is a boy born on a Tuesday. 👇 One is a boy born on January 2. 👇 One is a boy born on January 2 at 13:45:07. The more you specify the boy, the closer the probably approaches 1/2!

ICARM.io is a new NSF math institute with the goal to support the use of new technologies for mathematical reasoning, including interactive theorem proving, formalization, automated reasoning, and machine learning. They are currently soliciting proposals for workshops, summer schools, and more!

Another free #PreTeXt workshop, this time on a Monday (3/2), only one hour, and focused on creating a worksheet using the pretext.plus online editor. Register here: scholarlattice.org/collections/...

LingoTheGame.com is like if The Witness and a cryptic crossword had a baby, and that baby rejected Jonathan Blow's COVID skepticism (I assume/hope).

Prove the product rule with one weird trick: f(x,y)=xy df/dt = ∂f/∂x dx/dt + ∂f/∂y dy/dt = yx' + xy' Calculus teachers *hate* this!

Although I was joking about how one might "accidentally" do this in one variable calculus, it is actually correct if you view x^x as the composite of the function f(u,v) = u^v with the vector-valued function (u(x),v(x)) = (x,x). What I described is just the multidimensional chain rule.

Telling the 20 year olds about Mr Ed

All in all it's just a 'nother vacuous truth

This is funny, and also how I learned it is "Skull-uta" and not "Skull-tula" as I've seemingly misread it all these years.

Out of a good film already, this was by far the best scene in terms of dialog and framing. #KnivesOut #WakeUpDeadMan

Any other millennials see those emergency buttons on a college campus and get the intrusive thought to slam the buttons like they're beacons on the Agro Crag? Just me?

I before E except after F Unless sounding like "eh" as in reickless or Jeiff

I try not to come off as patronizing when I say this, but it kills me when I do a GitHub-related workshop and so many people insist on setting their repos to private. *Nobody cares about your WIP repos*, except the people trying to help you, and they need the repo to be public in order to do that!

Married with a kid and we're still victims.

Still some room to join our Getting Started With PreTeXt #MathSky @mathtech.org workshop! Sign up at scholarlattice.org/collections/...

I want to get back into the habit of writing and blogging regularly, so here is something: buttondown.com/j2kun/archiv...

Hey #MathSky. I don't talk enough about how amazing my colleagues are in my department, especially when I hear about the internal drama that goes on at some places. I'm very grateful to have both very talented and very collegial faculty to work with. And we're looking for a new department chair.

I gave @digitalocean.com my credit card information so I could be a paying customer, and then they locked my account lol. What a joke.

The best part of being in the math club GroupMe is that when your kid's Cub scout pack has an extra catering tray of chicken fingers left over after the banquet, you know who to call.

Class is cancelled, type starts at 2pm sharp.

Yeah we're watching the S.U.P.E.R. B.O.W.L: Strangers hUrl moon Pies Excitedly for maRdi gras ... B.O.W.L.

The alien ambassador sidled through the museum in awe. "You Humans have so much art! Do you have machines to make all paintings, poems, stories and songs?" "We experimented with that, briefly," the guide said. "But humans are both cheaper and more creative. And, well, we will make art regardless."

Netflix throwing some shade this evening

"Did you figure out how to fix the issue with Firefox?" No, but I did figure out how to put up a notice to try using Chrome when the thing is broken, so at least I'm no longer getting reports. 😅

One of the reasons I so greatly dislike the “can men and women be friends?” nonsense (yes, full stop, shut up) is that it casts suspicion on people with opposite-sex friends instead of where it more often belongs: on people with no opposite-sex friends.

Hey #MathSky, do you have questions about #education, #documents, or #accessibility? The @mathtech.org team is on Zoom for the next hour! mathtech.org/dropin

Our next "Getting Started with #PreTeXt" workshop is next week on Thursday, February 12, 12-2pm EST. Space is limited. Register for free: scholarlattice.org/collections/...

If anyone wants to take the already-fabulous q.uiver.app and create a version that produces PreFigure output (prefigure.org/docs/sec-net...), I would be eternally grateful.

Chips challenge would probably make a good dnd dungeon outline

\epsilon \mapsto \epsilon/2.

oh no someone accidentally made a listserv that includes every tenured faculty member i'm sure everyone with be normal about this and ignore it

ah hell i have to write an SQL query by hand today

Lots of fun at the first #MaPPChallenge this year across the country, here in Mobile, AL hosted by SouthAlabama.edu and Bishop.edu! Learn how to bring fun math research inspired puzzles to your campus at MaPPmath.org!
