Introductory Problem Solving Workshop
Presented by: Joyce Gong and Arin Cushman
New to math competitions and problem solving? Join our free relaxed problem solving workshop based on AMC 8 and MATHCOUNTS material. Suitable for middle school students. Enjoy pizza after the end of the class.
If this problem set is too hard, then you are not ready yet.
If this problem set is too easy, then consider our other classes.
Location: Brownson Hall BR-108, Manhattanville University

Recreational Math Seminar
Our main event, open to all levels. Presenters and topics vary from week to week.
Location: Brownson Hall BR-108, Manhattanville University
Time: Tuesdays 6-7:30 pm
Sept 8
Title: Word Puzzles and Monte Carlo Markov Chains
Speaker: Prof. Gautam Chinta
Abstract: Can randomness help solve a word puzzle? In this talk, we embed word puzzles into vast search spaces and construct a random walk to explore the possibilities. Using substitution cryptograms and computer demonstrations, we will watch nonsense gradually become readable English, investigate why purely greedy methods get stuck, and see how carefully designed randomness can make an enormous search manageable.
Bio: Professor Chinta is Professor of Mathematics at CUNY. He received his PhD in Mathematics from Columbia University and his undergraduate degree from Yale.
Sept 15
Title: Rubber Bands and Coffee Mugs
Speaker: Dr. Matt Cushman
Abstract: It's sometimes said that a topologist is a mathematician who can't distinguish between a coffee mug and a donut. We'll talk about why that is, and take a look at some other shapes to decide whether or not a topologist could tell them apart. What about a balloon with a string, versus one without? What about two linked donuts, versus two unlinked? We'll even work some of these configurations out with actual rubber bands and coffee mugs. We'll finish with a foray into the mathematics that studies HOW you can decide systematically if two shapes are the same or not.
Bio: Matt Cushman helps run the Westchester Area Math Circle. He has a PhD in Mathematics from the University of Chicago, BS and MS in Mathematics from Carnegie Mellon and worked in quantitative finance.
Sept 22
Title: Unlocking the Mysteries: The Enduring Power of Mathematical Constants
Speaker: Dr. Henry Ricardo
Abstract: Some numbers are so ordinary that we hardly notice them. Others are so strange that mathematicians have spent centuries trying to understand them. (Why does π keep appearing in places that have nothing to do with circles?). In this talk, we’ll take a tour through some of mathematics’ most curious constants, numbers from geometry, algebra, analysis, and combinatorics, and see surprising connections along the way. Bring your curiosity. I’ll bring the numbers.
Bio: Dr. Henry Ricardo Dr. Ricardo has been involved in the world of higher mathematics for almost 60 years, in both the academic field and in industry (IBM). He has graded AP Calculus exams for the College Board and has written two college textbooks. From 2008 to 2011 he served as Governor of the Metropolitan NY Section of the Mathematical Association of America. He retired from the City University of New York as Professor of Mathematics in 2009. He has been affiliated with the Westchester Area Math Circle since 2017, giving talks and conducting sessions on various topics for students participating in math competitions.
