Retail Pick of the Month: Glass Dot & Wave Moiré Coasters
This set of four glass coasters creates mesmerizing moiré patterns when stacked and turned.  When they’re not in use, arrange them to transform a simple dotted grid into a blooming circular array, or a wavy line into a dazzling optical effect.


Counting Connections
Wednesday, October 30, 6:30 pm

Here’s an innocent and well-known question: What is the maximum number of pieces of pizza you can get with n straight cuts?  Join visiting mathematician Paul Zeitz in an investigation that starts with this question and then dives even deeper.  Ultimately, an imaginative reinterpretation of geometric counting leads to a truly mean-spirited multiple-choice question that may just be one of the 20th century’s meanest math questions ever.  Learn more and register at counting.momath.org.

Professional Development at MoMath: “Chasing Rabbits: Building a Lifetime of Curiosity for, and Fascination with, Mathematics through Adventures in Arithmetic”
Tuesday, November 5, 9:30 am to 3:00 pm

In this full-day workshop, Sunil Singh and Dr. Chris Brownell, authors of Math Recess: Playful Learning in an Age of Disruption, will take participants on a wild journey of problem-solving and mathematical thinking that includes games, puzzles, and conundrums from the last 100 years — all rooted in dabbling and tinkering with numbers.  This workshop is geared for all K to 12 math educators who would like to strengthen their understanding of and interest in mathematics.  Learn more and register at pd.momath.org.

Solution Set: How to Solve Mathematical Puzzles — a minicourse featuring Peter Winkler
Tuesday, Nov 5, 6:30 pm — registration for individual classes 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: “Tales of Impossibility: The Problems of Antiquity” with David Richeson
Wednesday, November 6, 4:00 pm and 7:00 pm

“Nothing is impossible!”  While it is comforting to believe this greeting card sentiment — it’s the American dream, after all — there are impossible things.  Ancient Greek geometers and future generations of mathematicians tried and failed to square circles, trisect angles, double cubes, and construct regular polygons using only a compass and straightedge.  Join David Richeson, Professor of Mathematics at Dickinson College and Editor of Math Horizons, to try your hand at some of these unusual geometric construction techniques.  But get ready to fail — after two thousand years, all four of these “problems of antiquity” have been proved to be mathematically impossible!  Learn more and register at mathencounters.org.

The Mathematics of Wordplay
Thursday, November 7, 6:00 pm

Millions of word lovers and puzzle enthusiasts solve crosswords every day, in print and online.  Certainly it helps to have a big vocabulary when solving the daily crossword, but did you know how much math underlies the process of constructing a crossword?  Join puzzle constructor Nathan Curtis in exploring topics from information theory, geometry, and graph theory that explain how a crossword can come to be.  This event is brought to you with the generous support of Saul and Sandra Rosenthal.  Learn more and register at wordplay.momath.org.

Probability and Intuition — a dinner course for executives
Thursday, November 7, 7:00 pm (another standalone session offered on December 12)

99.99% of the decisions we make are made without the use of formal mathematics, yet math plays an important part in shaping our intuition.  Can we improve our intuition?  Can we identify and overcome the difficulties we humans have in dealing with probabilities?  Join Peter Winkler, MoMath’s 2019-2020 Distinguished Visiting Professor for the Public Dissemination of Mathematics, for a series of exclusive dinner events during which probability and decision theory will be explored in the context of puzzles — realistic or contrived — whose answers may surprise us.  The objective?  Have fun while discovering some new ways to deal with our uncertain world.  Attend individual dinners (each held at a local fine dining establishment) or sign up for all of them, but don’t delay — space is extremely limited for these exclusive events.  Learn more and register at intuition.momath.org.

Meet the Artist: Origami artist Matt Shlian

Math Encounters: “Primes and Zeros: A Million-Dollar Mystery” with Brian Conrey
Tuesday, January 7, 4:00 pm and 7:00 pm

Due to the New Year holiday, the January Math Encounters will take place on Tuesday, January 7, instead of Wednesday, January 1.  How can we quickly determine how many primes there are less than some huge number?  The great mathematician Georg Friedrich Bernhard Riemann proposed a solution 160 years ago — but we still haven’t been able to verify his hypothesis.  Join mathematician Brian Conrey, founding Executive Director of the American Institute of Mathematics, as he shares some of the colorful history surrounding the world’s greatest-ever math challenge.  Learn more and register at mathencounters.org.

Exhibit Tangents, new content
Thursday, January 9, 6:30 pm

Join visiting mathematician Paul Zeitz on another deep dive into more of your favorite MoMath exhibits.  You already know the exhibits are fun, but now you can peek under the hood to see the real mathematics lurking inside.  Not only will you enjoy a newfound perspective, but you’ll leave with some thought-provoking challenges you can continue to ponder even after you’ve left the Museum.  No questions are off the table!  Each session in this occasional series explores different exhibits.  Learn more and register at tangents.momath.org.

Family Fridays at MoMath presented by Two Sigma: “Pentagonal Pursuit: Solving a Century-Old Tiling Problem” with Lauren Siegel
Friday, January 10, 6:30 pm

Join MathHappens Foundation Director Lauren Siegel to learn about a remarkable 119-year-old story that has everything — top mathematicians, popular culture, surprise contributors, extreme dedication, tragedy, computer algorithms, and even quilting!  The fifteen pentagons that tessellate, or fill space without gaps or overlaps, will be offered for your enjoyment as wooden tiles ready for exploration and decoration.  You can follow your own observations, intuitions, and creativity or look to some inspiring examples from Marjorie Rice and others to make your own pentagonally pleasing designs.  Thanks to the generous support of Two Sigma, this program is free to attendees.  Register at familyfridays.momath.org.
