@mathyawp I'm teaching it this semester for the first time: using Epp's text (the "brief edition") and mastery grading (inspired by @RobertTalbert). I like all of the other ideas in this thread too!
"I don't think of myself as teaching math. I think of myself as teaching students problem solving. And by problem solving, I mean teaching students to solve problems they've never seen before." -Richard Rusczyk
Richard Rusczyk, founder of Art of Problem Solving, is developing a full elementary math curriculum, with the goal of bringing the problem-solving mindset to more than just self-selected math lovers. https://t.co/ZvYAUci4iT
Last year I wrote a paper on a small connection between entropy, algebra, and topology. Today, I’m happy to share a new article on the same ideas, this time written for a *wide* audience: https://t.co/aBa4CIvdGM A new 5 min. explainer video is out, too! https://t.co/TGeYJVajnb

New video! An adaptation of a post by @ncasenmare on contact tracing and privacy protection. It's highly counterintuitive that you can do this without tracking people's locations.

gravitational 3-body problems are great for chaotic dynamics. one of my favorites is the sitnikov system: given two equal massive bodies rotating about one another on ellipses, add a third tiny mass perfectly poised between them. give it a kick & what happens?
