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."
Everyone knows you can't do the same thing to both sides of a trig identity to prove it... right?
What kind of message does it send that game shows so often get mathematics wrong?
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?
What if we could invent a new notation for logarithms that was consistent with how we write exponents and radicals?
