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:

Math Circle Registration Form

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).

Fall Enhancement Workshop

In addition to allowing students to explore various fields of math through our talks series, our Fall Enhancement Workshop helps them hone the various skills involved in higher mathematics. The workshop, titled the Math Circle Fall Enhancement Program Workshop (FEP) will be held from Sep. 25 through Dec 4, on alternate 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 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 1982, 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?

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 .

Donations

Please consider donating to the Madison Math Circle. Our main costs consist of pizza and occasional supplies for the speakers. So far our costs have been covered by donations from the UW Mathematics Department as well as a generous gifts from private donors. The easiest way to donate is to go to the link:

Online Donation Link

There are instructions on that page for donating to the Math Department. Be sure and add a Gift Note saying that the donation is intended for the "Madison Math Circle"! The money goes into the Mathematics Department Annual Fund and is routed through the University of Wisconsin Foundation, which is convenient for record-keeping, etc.

Alternately, you can bring a check to one of the Math Circle Meetings. If you write a check, be sure to make it payable to the "WFAA" and add the note "Math Circle Donation" on the check.

Or you can make donations in cash, and we'll give you a receipt.
