John Horton Conway, one of the most brilliant mathematicians of recent times, died in April 2020. While contributing to many diverse fields of mathematics, he delighted in amusing people. One of his playful contributions to mathematics was in the subject of tiling (tessellations), and is called the "Conway Criterion." Any shape that conforms to his criterion will fill the plane with its copies, fitting together like jigsaw pieces, just by rotating the tile by 180 degrees repeatedly about certain points on its edges. To honor his memory, an app called Conway's Magical Pen has now been developed.

Join us tonight at 6:30pm EDT for an evening of exploration led by artist and technologist Anton Bakker, who will be joined by mathematician Doris Schattschneider and app developers Jonathan Bailey and Herman Tulleken. Learn how you can use the app to make freehand "Conway tiles" that are guaranteed to tile the plane. Your tiles can be simple or complex, straight or swirly, abstract or Escher-like — what you create is limited only by your imagination! Learn more and register at magicpen.momath.org.

Happy #NationalWineDay! Did you know that “wine tears,” the small droplets that fall back into your glass when you swirl your wine, emerge from an unusual circular shockwave in the liquid created by a balance of 3 physical effects: a Marangoni stress effect, gravity, and bulk surface tension (the surface tension of the large pool of wine in the base of a glass)? If you remove any of those three effects, wine tears don't happen...Math is everywhere!

Ethan is holding a true coin and is told that among five identical looking coins on the table, one is counterfeit. The counterfeit is heavier or lighter than a true coin.

How can he find the counterfeit in two weighings using a simple two-pan balance? #MathMonday
