Math Help: If I have a nonlinear transformation T: R^m -> R^n, what do I call the set of solutions to T(x)=0? Is it just roots or zeros? Or is there a fancier name for it?

Hear me out: Instead of multiple classes meeting 3-4X a week for 15 weeks. One class meets 3-4 hours per day (2 hour morning session + 2 hour afternoon session) for 15 days.

Been seeing lots of @Desmos 3D discussion around surfaces of revolution for Calculus. While parametrics are great for showing the act of rotation (see: desmos.com/3d/1a7f86ac77), I'm also loving this strategy, accessible to students who have seen equations of circles before:

Just finished #GradingForGrowth. If you are even remotely interested in the alternative grading movement, I highly recommend it. Even if you’re not, it might change your mind.

Friends in academia, let this serve as a reminder that a promotion without a significant raise isn’t a promotion, it’s a title change. Also, promotions come with a shift in responsibilities, not only more responsibilities. Don’t sell yourself short.

We need people to do X. We refuse to pay people to do X. Why does nobody want to do X?

Student: Can we talk about D12? Me: The rap group or the standard? Either way the answer is yes.

It’s only a matter of time before students are able to work a problem, scan it, and have AI leave feedback and grade their work. I wish that day was today.

Any #MTBoS folks have suggestions for intro matrices / linear algebra books? I've had success using Holt in the past but am looking into more affordable alternatives.
