=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.

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.

==Donations==
Please consider donating to the Madison Math Circle. As noted in our [https://www.math.wisc.edu/wiki/images/Math_Circle_Newsletter.pdf annual report], 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 a private donor. But our costs are rising, primarily because this year we expect to hold more meetings than in any previous year. In fact, this year, we expect to spend at least $2500 on pizza and supplies alone.


So please consider donating to support your math circle!  The easiest way to donate is to go to the link:


[http://www.math.wisc.edu/donate Online Donation Link]
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.


There are instructions on that page for donating to the Math Department.  <b> Be sure and add a Gift Note saying that the donation is intended for the "Madison Math Circle"!</b>  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.
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.  


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. 
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!


Or you can just pay in cash, and we'll give you a receipt.

A classic problem in topology is to decide whether one surfaces can be deformed into another, without creating any holes or connecting any new points (stretching and bending is allowed!). If you can do so, such surfaces are considered 'the same.' We will formalize this notion and classify all closed surfaces, along the way answering such questions as whether a coffee cup is the same as a donut.

|-
| bgcolor="#BDBDBD"  | 
The idea is to give a simple overview of sound waves by introducing sines and cosines and some of their basic anatomy (amplitude and frequency).  We will then have a computational component where the students create their own sound waves by fiddling with parameters in the sines and cosines (again, amplitude, frequency and different superpositions of the sines and cosines). They will actually be able to see plots of their waves AND listen to their waves.  Finally, if time permits, the students will use their own sound waves to make Oobleck dance.  This will bring the exercise full circle in that they will be able to see their very own sound waves in action.

Like most people, I've often considered opening an eight dimensional grocery store.  Of course, the main difficulty with this plan is that I'd need some way of neatly stacking all of the eight dimensional fruit that I'd be selling.  In this talk, we'll explore a variety of elementary counting problems, discover that nearly all elementary counting problems are really the same problem, and we'll apply these new insights to determine how to stack 8 dimensional fruits into neat 8 dimensional pyramids.

A tiling is a way of covering the plane with geometric shapes such that there are no overlaps or gaps. If you have any tile in your home (maybe in your kitchen or bathroom) that is most likely an example of a tiling. Come learn about the cool math behind tilings and about the coolest tiling of all, the Penrose tiling.

|-

GPS is a system of satellites circling the Earth at a height 12,500 miles. That means you could easily fit both Mars and Venus in the distance between your phone and each car-sized satellite hovering in space. Once considered science fiction, GPS is now a part of our everyday life: we can use it through our phones, through our car navigation, and even some watches. Simple math equations lie at the heart of this system, and we will write them down, understand what they mean, and figure out how to solve them.

What do pulling gold coins out of a a hat have to do with the famous Monty Hall "Goat Problem" in which you are a game show contestant trying to pick out the one prize hidden behind one of three doors?  Come and find out while savoring some chocolate gold coins. We will also discuss a jailer problem in which an infinite number of jailers try to free an infinite number of prisoners. If time permits, other fun problems will be discussed.

1, 2, 3,..., infinity? What is infinity? Is infinity plus one bigger than infinity? Beginning by figuring out what we mean when we say to collections of objects have the same number of things we will slowly work our way deep into the world of infinity. This world is often weird and counterintuitive, and we shall explore it!

The question of deciding whether two things are the same comes up in many different places in math. In this session we'll consider the problem of deciding if two networks or "graphs" are the same. This leads to some entertaining and challenging puzzles. We will also learn a bit about how people try to solve similar problems using computers.  This problem has applications in the design of electronic circuits and in searching for organic chemical compounds within large databases.

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).


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!
