What is a Math Circle?

The Madison Math Circle is a weekly series of mathematically based activities aimed at interested middle school and high school students. It is an outreach program organized by the UW Math Department. Our goal is to provide a taste of exciting ideas in math and science. In the past we've had talks about plasma and weather in outer space, video game graphics, and encryption. In the sessions, students (and parents) are often asked to explore problems on their own, with the presenter facilitating a discussion. The talks are independent of one another, so new students are welcome at any point.

The level of the audience varies quite widely, including a mix of middle school and high school students, and the speakers generally address this by considering subjects that will be interesting for a wide range of students.

After each talk we'll have pizza provided by the Mathematics Department, and students will have an opportunity to mingle and chat with the speaker and with other participants, to ask questions about some of the topics that have been discussed, and also about college, careers in science, etc.

The Madison Math Circle was featured in Wisconsin State Journal: check it out!

All right, I want to come!

Our in person talks will be at, Monday at 6pm in 3255 Helen C White Library, during the school year. New students are welcome at any point! There is no fee and the talks are independent of one another. You can just show up any week, but we ask all participants to take a moment to register by following the link below:

All of your information is kept private, and is only used by the Madison Math Circle organizer to help run the Circle.

If you are a student, we hope you will tell other interested students about these talks, and speak with your parents or with your teacher about organizing a car pool to the UW campus. If you are a parent or a teacher, we hope you'll tell your students about these talks and organize a car pool to the UW (all talks take place in 3255 Helen C White Library, on the UW-Madison campus, right next to the Memorial Union).

Spring Enhancement Workshop

This Spring, we have a guest organizer for our Math Circle: Peter Juhasz teaches mathematics (grades 7-12) at Szent István Secondary School in Budapest. He has extensive experience teaching mathematics and mathematics education to college/university students, as well as teaching mathematics to secondary students. Péter is the chief organizer of various mathematics camps in Hungary, including those founded by Lajos Pósa and the Camp of Mathematical Amusements. He directs the Joy of Thinking Foundation, whose aim is to promote mathematics education of gifted students in Hungary.

Our Spring Enhancement Workshop helps students hone the various skills involved in higher mathematics. The workshop, titled the Math Circle Spring Enhancement Program Workshop (SEP) will be held from February 19 through May 6, on Mondays from 6:00pm - 7:00pm at the UW-Madison campus. Please see our schedule below for details.

The topics for this workshop will cover an introduction to constructing mathematical arguments and proofs, understanding how to generalise simple mathematical ideas, and learn how to discover math for one's self. We will build these skills through collaborative problem solving sessions while learning about graph theory, game theory, and other cool areas of mathematics.

We want to invite any middle school or high school students curious about math to join! If you are interested, please register using the form below:

As always, this workshop is free and only requires your curiosity and participation! We hope to see you there!

Abstract 10/2

Uri Andrews

Title: How many paradoxes are there?

"This statement is false". That's the so-called liar's paradox. (Think through why that statement cannot be either true or false). A paradox is a statement or collection of statements that cannot be meaningfully assigned truth values. Aristotle thought that all paradoxes were essentially the same as the liar's paradox. In 1985, Yablo found a different paradox (though there is some disagreement here). A brand new paper claimed to show that there are only 2 paradoxes (Yablo and the liar's paradox). I'll talk about all these topics and also a brand new paradox. Are there more than 2 paradoxes after all?

Diego Rojas La Luz

Title: How to Not Die While Eating a Poisoned Chocolate Bar

We are going to talk about Chomp, a game where you take turns eating chocolate and you try not to die from poisoning! This is one of those very easy-to-state combinatoric games which happens to be very hard to fully analyze. We'll see that we can say some rather surprising things regarding winning strategies, so stay tuned for that. Who wants to play?

Abstract 10/30

Oh Hoon Kwon

Title: Your (Life) Turning Points: Chasing Angles for Proofs

We're bringing a fresh approach to Euclidean geometry by incorporating physical movements involving a pencil to illustrate proofs related to angle concepts. This inventive method acts as a potential link between inductive, exploratory techniques and deductive proofs. It provides students with a new perspective on Euclidean geometry, particularly in the context of angle concepts, making it an enjoyable and captivating way to engage with the subject.

Abstract 11/13

Aleksandra Cecylia Sobieska

Title: Trapezoid Numbers

Perfect squares are numbers that can be represented as a square arrangement of dots, like 1, 4, 9, 16, and so on. This Math Circle, we will investigate a similar question: what numbers can be represented as a trapezoidal arrangement of dots?

Directions and parking

Our meetings are held on the 3rd floor of Helen C. White Hall in room 3255.

Parking. Parking on campus is rather limited. Here is as list of some options:

There is a parking garage in the basement of Helen C. White, with an hourly rate. Enter from Park Street.
A 0.5 mile walk to Helen C. White Hall via these directions, many spots (free starting 4:30pm) in Lot 26 along Observatory Drive.
A 0.3 mile walk to Helen C. White Hall via these directions, many spots (free starting 4:30pm) in Lot 34.
A 0.3 mile walk to Helen C. White Hall via these directions, 2 metered spots (25 minute max) in front of Lathrop Hall.
A 0.2 mile walk to Helen C. White Hall via these directions 6 metered spots (25 minute max) around the loop in front of Chadbourne Hall .
