Thoughts on mathematics and education — their intersection, their differences, and their union.
Can high school students really learn algebraic geometry? And what could it teach us about mathematics education?
My song on the dance game Pump it Up XX is named after a famous theorem from group theory. Here's an explanation of what it's all about.
Those deliberately ambiguous order-of-operations problems that plague social media may actually be evidence of a mathematical "language shift."

A presentation I gave at the Georgia Mathematics Conference, about slyly introducing precalculus students to a discrete version of calculus.
Statement: They're terrible. Reason: They don't help students reason — if anything, they just get in the way.
Who knew the Axiom of Choice could help me decide whether to get guacamole for an extra $1.95?
