These axes are all wrong! Quality of memes does not define the state of the world, rather the state of the world defines quality of memes. #mathteacher #axesmatter #xisindependent #yisdependent

Teaching my compressible flow course online is giving me the opportunity to answer some long-standing questions, such as: Just how fast *is* that eagle in the @USPS logo going? Turns out, about Mach 4.9...

Is it good/bad/other than I have literally sung “🎵 tell me why 🎶” to my classes when that is the variable we’re solving for?

I can love kids and love being in a classroom, and ALSO be utterly paralyzed and terrified of the idea of returning to the physical schools this fall...

MATH IS NOT APOLITICAL. Y’all ever seen a misleading graph? Seen people with power use numbers manipulated for their benefit to win arguments/contracts? How about who’s ideas are valued and how we portray “genius” in film? MATH IS NOT APOLITICAL.
