Fall 2022 Schedule

We are offering 4 free sessions every week. All the sessions below are free and open to the public, but we do take donations!

Descriptions


  1. Recreational Math Seminar

Our main event, open to all levels. Presenters and topics vary from week to week.

Location: Brownson Hall 14, Manhattanville College

Time: Tuesdays 6-7:30 pm (weekly)


  1. Introductory Problem Solving Workshop

Presented by: Grace Lin, Chen Li

This is a relaxed problem solving workshop based on Moscow Math Circle material. The course will be on a similar level like last year, but it will include new problems only.

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 14, Manhattanville College

Time: Tuesdays 5-5:50 pm (weekly)


  1. Intermediate Problem Solving Workshop

Presented by Chinmayi Goyal, Jai Paradkar, and Jason Shi

Topic based seminars covering algebra, geometry, combinatorics, and number theory. The fall semester will concentrate on AMC 10/12 problems. The spring semester will introduce AIME level problems.

Online only

zoom: https://us06web.zoom.us/j/89028596167?pwd=MWQ1UktDRERBSW9oY1dDVkNhMlg1Zz09

Time: Thursdays 6-6:50 pm (weekly)


  1. ARML Training

Presented by: Mathew Zhao, Jason Zhong, and Andrew Tu

This class is designed for those who are comfortable with the AMC 10/12 and wish to train for more advanced contests. We will be using past ARML problems.

Location: Brownson Hall 14, Manhattanville College

Time: Sundays 3-4:30 pm (weekly)

Recreational Math Seminar

Time: Tuesdays 6-7:30 pm (weekly)

Sept 20, Matt Cushman - Platonic Solids

We all know what a triangle, square and hexagon are. You may have learned about polygons and regular polygons in geometry class. All of these objects dwell in two dimensions.. what would be their analogue for three dimensions? Join us as we explore this question, touching on a web of ideas running from the ancient Greeks (Plato), through Descartes and Euler through Gauss.


Sept 27, Yi Lin - Bayes Rules

Yi Lin will be leading a discussion of Bayes Rule:

Bayes Rule is the foundation for much of statistical and scientific reasoning. It's even been described as the most important equation for Machine Learning! Join our discussion of basic concepts in conditional probability with examples leading to Bayes formula and its applications.


Oct 4 Matt Cushman - "Fermat's L(ittle) Theorem"

Abstract: Fermat's Last Theorem famously was proved in the 1990s by Andrew Wiles after centuries of work by brilliant mathematicians. Fermat has another "L" theorem, which is actually much more important and which he actually proved. Known as "Fermat's Little Theorem", this forms the basis for a lot of number theory and algebra. We will discuss it, and a couple of different proofs as well as some applications.


Oct 11, Henry Ricardo (Professor of Mathematics at CUNY, retired)

Title: Digital Roots and the Hidden Design of the Universe

Abstract: Mystical qualities have been attributed to numbers by philosophers and mystics throughout the

ages. In particular, the digital root of a number has been endowed with cosmological

significance.

We will discuss (mathematically) the definition and basic properties of this number-theoretic

function, as well as more sophisticated results. For the purposes of our math circle, we note that

the digital root and related concepts have appeared in various mathematical and programming

competitions over the years. Audience participation will be encouraged. Exercises and

references will be provided.


Oct 18, Jon Lenchner (Research Scientist, IBM)

Title: On Some Card Games Related to the Card Game SET

Abstract: Dr. Lenchner will describe two mathematical card games that I have created that have some similarities to the popular card game SET. I will describe various mathematical properties of these games, allow the audience to play a few sample hands, and then I will describe the making of the physical and online versions of the games. I will also mention a handful of open problems connected to the games.

Nov 1, Yicheng Zhong (title and abstract TBA)

Other Contests?

If you think there are other contests we should be hosting or sending teams to, please let Paul know. Please note that he is unable to provide extra labor, and so this is only possible if you are also vounteering your time to organize the event.
