# What is it?

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.

**Important:** After each talk we'll have **pizza** provided by the department, and students will have an opportunity to mingle and chat with the speaker to ask questions about college, careers in science, etc.

# Alright, I want to come!

Great! If you're 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 on the UW campus). **We'd also appreciate if you email us the dates that your group will be attending**, so we can purchase the appropriate amount of pizza.

If you're a student, speak with your high school teacher about organizing a car pool to the math night (and tell us how many people are coming!)

# Questions?

If you have any questions, suggestions for topics, or so on, just email the organizers: math-night@math.wisc.edu.

## Talks this semester

### Introduction to Mathematical Proofs

October 3rd, 2011

**Introduction to Mathematical Proofs**

The first ever meeting of the Madison Math Circle will describe mathematical proofs using many examples from 2D and 3D geometry, algebra, logic, puzzles, and games (yes, games!). Free and open to the public. Middle school and high school students are invited to attend.
