[[Image:logo.png|right|600px]]
<font size="4" color = red>We are thrilled to announce that, starting on September 28, we have a beautiful new room for our Math Circle: Room 3255 in the Helen C White Library, which is right next to the Memorial Union on the UW Campus.  We apologize for the inconvenience that our room changes have caused but we think this will be a great fit.</font>
 
  
=Weekly Meeting=
+
For the site in Spanish, visit [[Math Circle de Madison]]
We have a weekly meeting, <b>Monday at 6pm in 3255 Helen C White Library</b>, during the school year.  <b>New students are welcome at any point! </b> There is no required registration, no fee, and the talks are independent of one another, so you can just show up any week. See below for directions.

=COVID-19 Update=
 +
UW-Madison is canceling all major events and moving to “virtual instruction” for the rest of the Spring 2020 semester. The Madison Math Circle will also be canceling all in-person Math Circle meetings for the remainder of this semester.
  
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).

'''We will have a few virtual Math Circle meetings on Monday, April 6, April 13, and April 20 at 4-4:45pm. Please join our email list (send a blank email to join-mathcircle@lists.wisc.edu) to receive updates about these virtual meetings and links to join us each week! We plan to send out a video about an interesting math topic to watch and think about beforehand and will answer questions and discuss the video during the meeting.'''

==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.  Our costs have been covered so far by donations from the UW Math Department plus 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.

''How to SEE Sound''
 
  
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.

A shape in the plane (i.e. a shape you can draw on a piece of paper) is called Kakeya if we can place the needle within the shape, and by only rotating and shifting the needle within the shape (no lifting!) we can get the needle to point in all directions. We will think about what sort of shapes are and aren't Kakeya, how this affects their geometry, and how small these shapes can be.

Have you ever sat next to someone in the airport or airplane who plays sudoku? Have you ever tried to play yourself? When you play, do you have some strategies that help you to complete the puzzle? It turns out that there is some deep mathematics behind this simple game. Come to math circle this week to learn about it, and maybe you can help the person next to you solve his/her sudoku!

''The Geometry of Hockeysticks and Eight Dimensional Oranges''
 
  
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.

''Are these networks the same?''
 
 
 
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.

''Donuts and coffee cups: the topology of surfaces''

[https://www.math.wisc.edu/wiki/index.php/Math_Circle_Presentations  Advice For Math Circle Presenters]
  
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.

COVID-19 Update

UW-Madison is canceling all major events and moving to “virtual instruction” for the rest of the Spring 2020 semester. The Madison Math Circle will also be canceling all in-person Math Circle meetings for the remainder of this semester.

We will have a few virtual Math Circle meetings on Monday, April 6, April 13, and April 20 at 4-4:45pm. Please join our email list (send a blank email to join-mathcircle@lists.wisc.edu) to receive updates about these virtual meetings and links to join us each week! We plan to send out a video about an interesting math topic to watch and think about beforehand and will answer questions and discuss the video during the meeting.

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!

We have a weekly meeting, 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, so 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).


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:

Email list

The best way to keep up to date with the what is going is by signing up for our email list. Send an empty email to join-mathcircle@lists.wisc.edu

Contact the organizers

The Madison Math Circle is organized by a group of professors and graduate students from the Department of Mathematics at the UW-Madison. If you have any questions, suggestions for topics, or so on, just email the organizers here. We are always interested in feedback!

Donations

Please consider donating to the Madison Math Circle. As noted in our 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:

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

Help us grow!

If you like Math Circle, please help us continue to grow! Students, parents, and teachers can help by:

  • Like our Facebook Page and share our events with others!
  • Posting our flyer at schools or anywhere that might have interested students.
  • Discussing the Math Circle with students, parents, teachers, administrators, and others.
  • Making an announcement about Math Circle at PTO meetings.
  • Donating to Math Circle.

Contact the organizers if you have questions or your own ideas about how to help out.

Date Location Speaker Title Abstract
October 7, 2019 2:45pm East High Solly Parenti Tangled Up in Two Every tangled cord you have ever encountered is secretly a number. Once you learn how to count these cords, cleaning your room will be as easy as 1-2-3.
November 4, 2019 2:45pm James Madison Memorial Caitlyn Booms Sneaky Segments We call a line segment drawn between two lattice points in the coordinate plane sneaky if it does not pass through any other lattice points. During this presentation, we will try to understand exactly when this happens, and we'll discuss how to calculate the probability that two randomly chosen lattice points are connected by a sneaky segment.
November 11, 2019 2:45pm East High Maya Banks Tic-Tac-Topology Tic-Tac-Toe is a game usually played on a flat piece of paper. In this standard setting, there is winning strategy--that is, if the player who goes first chooses their moves correctly, they will never lose. But we can also play Tic-Tac-Toe on a surface that isn't lying flat in a plane! In this talk, we will explore the game of Tic-Tac-Toe on cylinders, donuts, and even some wilder surfaces. We'll look for optimal strategies, and learn some topology in the process.
December 16, 2019 2:45pm James Madison Memorial Daniel Erman Really Big Numbers We will discuss the role that really really, really big numbers play in modern mathematics and in science. This will be a discussion of estimation and an introduction to some of the ways that mathematicians express unfathomably big numbers.

March 9, 2020 2:45pm East High Michel Alexis Kakeya Needle Sets Take a 1-inch needle. A shape in the plane (i.e. a shape you can draw on a piece of paper) is called Kakeya if we can place the needle within the shape, and by only rotating and shifting the needle within the shape (no lifting!) we can get the needle to point in all directions. We will think about what sort of shapes are and aren't Kakeya, how this affects their geometry, and how small these shapes can be.
