 Daniel Erman Title: Welcome to the Madison Math Circle! Abstract: At the Madison Math Circle, we aim to give a flavor for the creative type of thinking that goes into mathematical research. In this week's interactive activity, students will explore questions related to Mobius strips, developing their own conjectures.

 Betsy Stovall Title: Math is a game! When mathematicians are working to solve a theoretical problem, it often helps to imagine that we are playing a game: What could our opponent do to make our job as difficult as possible, and what is our strategy to defeat them no matter what move they make? In this session, we will try this out by playing several games and trying to come up with winning strategies.

 Rachel Davis Title: Thinking outside the box Abstract: We will try some geometric puzzles related to area, volume, and dimension using techniques such as drawing diagrams, looking at special cases, using symmetry, and changing perspective.

 Solly Parenti Title: Hackenbush Abstract: I come from an alien world where we spend all of our time playing a game called hackenbush. I'd like to introduce y'all to this game so you don't embarass yourself if you come visit my planet.

 Mihaela Ifrim Title: Escape of the Clones! Abstract: We wish to find an invariant (an invariant is a quantity that doesn't change no matter how the process plays out). By playing couple of games will help us find some! The main game we will play is Escape of the Clones! Promise you will like it!

 Ryan Julian Title: Recursion for Fun and Profit Abstract: Beginning with the classic Towers of Hanoi puzzle, we'll explore several puzzles whose solutions can often be found by thinking recursively. We'll also discover how recursion and related methods of simplifying problems can be used to create efficient algorithms to solve a variety of practical problems.

 Speaker Title: Goldbug Variations Abstract ```I'll discuss the motion of little mathematical bugs: they hop around the positive integers, flipping direction arrows as they go. How many such bugs drop off the line at -1, and how many escape to infinity? Next, we tackle a similar problem in the plane, and discover beautiful geometrical patterns, known as Propp Circles. ```

 Speaker TBD Title: How to make it as a Hackenbush player in the planet Zubenelgenubi 4 Abstract: In the distant planet of Zubenelgenubi 4, we live our life without numbers. I know, how do we pass our time if we can't construct a smartphone without numbers? The answer is that we have invented an extremely violent sport about chopping down trees called Hackenbush, and playing this game is an essential social skill in Zubenelgenubi 4. I will teach you how to play the pen and paper version of Hackenbush, and hint at how learning this game leads to a kind of math that is highly illegal in 254,233 planetary systems.

 Speaker: Alisha Zacharia Title: Fractals, Fractions and Fibonnaci. Abstract: Let’s go on a history tour! We’ll visit some math objects that intrigued generations of mathematicians and explore connections between them. We'll observe something that happens a lot in modern mathematics: discovering connections among seemingly unrelated things! Through this talk I hope to introduce you to how vital it is for mathematicians today to be able to effectively communicate with and teach each other even if they work in very different branches of mathematics.
