# What is it?

The UW-Madison math department organizes a series of mathematically based activities 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. Often, students are asked to explore related problems on their own. 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. The level of the audience can vary widely, 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.

# Alright, I want to come!

Great!

Sign up for our email list: https://lists.math.wisc.edu/listinfo/math-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 (and tell us how many people are coming so we can purchase the appropriate amount of pizza!)

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 Ingraham Hall room 120, on the UW-Madison campus).

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

- Directly in front of Ingraham hall, 2 metered spots (25 minute max) in Lot 11 off of Observatory Drive.
- A 0.2 mile walk to Ingraham Hall via these directions, many spots (
**free starting 4:30pm**) in Lot 26 along Observatory Drive. - A 0.3 mile walk to Ingraham Hall via these directions, many spots (
**free starting 4:30pm**) in Lot 34. - A 0.2 mile walk to Ingraham Hall via these directions, 2 metered spots (25 minute max) in front of Lathrop Hall.
- A 0.3 mile walk to Ingraham Hall via these directions 6 metered spots (25 minute max) around the loop in front of Chadbourne Hall .
- For more information, see the UW-Madison Parking Info website.

# Questions?

If you have any questions, suggestions for topics, or so on, just email the **organizers** (Lalit Jain, Dan Erman, Gheorghe Craciun, and Philip Matchett Wood): math-circle-organizers@math.wisc.edu.

## Abstracts

### Betsy Stovall

*Geometric Addition*

Abstract: We will learn some neat geometric tricks for quickly and painlessly computing some surprisingly large sums.

### Jon Kane

*Rows of Roses*

Abstract: Let’s talk about the sine and cosine functions. One does not need to use very much information about these commonly seen functions in order to understand a large number of curves which can be drawn by graphing sine and cosine in Cartesian and polar coordinates. We will see sine curves, sums of sine curves, Lissajous figures, cycloids, hypocycloids, epicyclodes, and, of course, many rows of roses.
