Summertime & the mathematics is... easy? This summer, SMI-NY will be organizing Sunday Mathematical Feasts on beautiful, bucolic Governors Island, a 15 minute ferry ride from the southern tip of Manhattan. For six Sundays, starting June 5th and running until August 21st, SMI-NY will host mathematical events for visitors from 8 to 80 to get "into" recreational mathematics, whether that be solving "knotty" problems, bulding cube puzzles or mixing the perfect bubble concoction. All events will be held at Building 11 in Nolan Park, with continuous admission from 12 noon to 3:45 pm. Childen under 18 must be accompanied by an adult, with a limit of 2 children per adult. Admission is free, although we do request a $5 donation to cover materials and programming fees.

Knots, Wires & Bands

Explore the mysterious world of topology, the study of distortion. Learn about how to use mathematics to magically tie a knot in a rope without letting go of the ends, as well asperform daring feats of escape. Build a clever "topological puzzle" and perform magic tricks using only a scissor and a strip of paper.

Let’s Party With Parity

“Parity” is an important concept in mathematics; learn more about it by turning over wine glasses, playing card games,
solving equations and flying helicopters. You don’t need a pilot’s license to learn about parity!


August 21st
