Now offering online programming!

Tween Primes, MoMath's book club for tweens and teens: This month, Tween Primes features Humble Pi: When Math Goes Wrong in the Real World by Matt Parker.  What happens when math goes wrong in the real world!  In this hilarious book, stand-up comedian and mathematician Matt Parker explores the glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team.  Learn about the bizarre ways that a misplaced decimal point upended the stock market, a unit conversion error caused a plane to crash, or when someone divided by zero and stalled a battleship in the middle of the ocean.  Getting it wrong has never been more fun.   Friends and good math reads: what better way to spend an evening?  5:30 pm – 6:30 pm ET (New York).

Unlimited is back, in a new online format!  Come spend an hour or more with your peers, enjoying interesting activities and interactive social games, all led by an experienced MoMath educator.  6:30 pm – 8:00 pm ET (New York).

These are live-streamed events.  Occasional video recordings are made available for a fee at
