Solution Set: How to Solve Mathematical Puzzles — a six-session minicourse
Tuesday, October 1, 6:30 pm — prorated registration is available
When someone poses a puzzle, is your first instinct to run?  Many very intelligent people think they’re bad at puzzle-solving — and always will be.  And most of them are wrong.  Like many things in life, puzzle-solving is an acquired skill; a bit of experience and a few tips can go a long way.  Of course, there’s no set way to solve puzzles; if there were, they would be textbook exercises, not uniquely tricky conundrums.  Join Peter Winkler, MoMath’s 2019-2020 Distinguished Visiting Professor for the Public Dissemination of Mathematics, as he helps us discover that each puzzle has its own logic.  A world of fun and satisfaction awaits once you find your way in!  Learn more and register at solutions.momath.org.

Math Encounters: “Paradoxes in Probability: Surprising Results and Why They Matter” with Alon Amit
Wednesday, October 2, 4:00 pm and 7:00 pm
Probability theory has a unique distinction among mathematical fields: it is often at odds with human intuition, sometimes very sharply so.  Beyond setting up various apparent “paradoxes” of intuition or logic, those counterintuitive aspects sometimes have quite dramatic manifestations in real-life situations.  Test your intuition on a variety of simple problems and explore how such paradoxes have crept into scientific research, policy making, and even executive boardrooms!  Learn more and register at mathencounters.org.

Meet the Artist: Origami artist Jeannine Mosely
Thursday, October 3, 6:30 pm
Meet artist Jeannine Mosely, well known for her origami models created from business cards, especially her largest models, created from thousands or even tens of thousands of cards.  Jeannine has also developed mathematical techniques for designing and analyzing curved origami models.  Two of her pieces, Hidden Stars and Sails, are currently on display in the Math Unfolded exhibition at the National Museum of Mathematics.  Meet the Artist talks will continue through the end of the year; visit artist.momath.org to register and to see additional dates and artists.

Japanese Puzzle Party
