[[Image:logo.png|right|600px]]
The UW-Madison math department organizes a series of talks aimed at interested middle school and high school students throughout the semester. Our goal is to present fun talks that give students a taste of interesting ideas in math and science. In the past we've had talks about plasma and weather in outer space, the way images are shaded in video games, and how credit card numbers are securely transmitted over the internet.

=What is a Math Circle?=
Great! 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 (and tell us how many people are coming so we can purchase the appropriate amount of pizza!)

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.
  
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 Van Vleck Hall room B231, on the UW-Madison campus).
+
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.
'''We'd also appreciate if you click the "Register" link for the date that your group will be attending.'''

'''Parking''' on campus is free at most (but not all) outdoor parking lots after 4:30pm. Parking lots #25 (Elizabeth Waters) and #26 (Observatory Hill) may be the most convenient. These parking lots are on Observatory Drive just west of the intersection with Charter Street. If you park there, then walk east along Observatory Drive to the top of Bascom Hill, then turn right to Van Vleck Hall. See also the map at http://www.map.wisc.edu/?keyword=public%20parking

So you think you can add two numbers, three number, even a lot of numbers together? Well, can you add an infinite number of numbers together?
 
See how thinking about infinite processes can be used to add infinite sums, evaluate repeating decimals, understand infinite continued fractions, and calculate areas and volumes. Also see what strange things can go wrong when dealing with infinity.

==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:
  
Taffy pullers are devices used to make candy or bread. They are very

[http://www.math.wisc.edu/donate Online Donation Link]
interesting mathematically: we can relate the number of folds of dough
 
to some famous mathematical sequences.  Some surprising numbers pop
 
up, like the Golden mean but also its lesser-known cousins.  We can
 
use this knowledge to improve existing devices. (Warning: no actual
 
taffy will be made. Sorry.)
 
  
===Guarding an Art Gallery===
+
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.
  
<span style="background:#00FF00">February 18th, 2013, '''6pm''', Van Vleck Hall room B231, UW-Madison campus</span>

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.
  
How many guards does it take to guard an art gallery so that every spot in the gallery can be seen by at least one guard?  We will explore this question and find an upper bound on the number of necessary guards based only on the number of walls in the gallery.

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

* Posting our [https://www.math.wisc.edu/wiki/images/Math_Circle_Flyer_2020.pdf '''flyer'''] at schools or anywhere that might have interested students.

espionage, treason, and sibling rivalry provided Polish mathematicians the
 
necessary ingredients to break the unbreakable.  This talk is geared towards
 
the general public, with no specific expertise in mathematics assumed.

COVID-19 Update

Due to COVID-19, all math circle events are canceled for Fall 2020.

We look forward to seeing you back in Spring 2021.

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.


MathCircle 2.jpg MathCircle 4.jpg


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 usually have a weekly meeting, Monday at 6pm in 3255 Helen C White Library, during the school year. However, in Spring 2021, we will be meeting virtually on the first Monday of each month at 5pm. See the schedule and link below. 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).
