Math Hour | Math Hour Olympiad | Past Events | UW Math Circle |

Each spring, Seattle-area middle- and junior high-school students are invited to participate in the Monthly Math Hour on the University of Washington's campus. The Monthly Math Hour at the UW is a series of talks that will take place from **1-2pm on Sunday afternoons** to introduce students to the beautiful and exciting world of mathematics. The lectures are given completely **free** of charge in Savery Hall room 260.

Well-behaved parents and teachers are also welcome to attend with the permission of their children. Siblings are free to join in, too.

There will be time for questions and further discussion after the talk.

To receive information about future events, please check back or click here to join our mailing list.

Do you think that everything there is to know about geometry was already discovered ages ago? Think again. Since the time of Euclid, the history of geometry has been a dramatic saga that your middle school teachers probably won't tell you about. It led, more than a century ago, to the mind-bending mathematical discovery that the three-dimensional space we live in might be "curved," in much the same way as the two-dimensional surface of the earth is curved.

In this talk you'll have a chance to learn what it could possibly mean mathematically for space to be curved, how we can detect it, and the fascinating story of how we got from Euclid to here. Along the way, you'll find out about "proofs" by professional mathematicians that turned out to be wrong, bitter personal battles over who was right and who was wrong, a million-dollar prize for solving a mathematical problem, and a mysterious modern-day Russian mathematician who earned it but doesn't want it.

When you imagine what a mathematician does all day, you probably picture someone standing at a chalkboard covered in equations and numbers. It’s true that many of us do fulfill this stereotype at times, but we also draw amazing and beautiful pictures and think about things that may not seem obviously to be mathematical. In fact, there are many mathematicians who devote their time to thinking about knots. (Think: tying a knot in your shoelace or trying to untangle your headphones.) Some of us even do research on games! We invent interesting games then try to figure out what strategies players can use to win. In my talk, I will show how these two areas of research may actually be combined into an incredibly fun kind of mathematics. We’ll play several games using knots and links and discuss ways we can “stack the deck” and guarantee ourselves a win.

How many museum guards do you need to post to see every bit of wall-space in a weird art gallery having *N* straight walls that meet at funny angles? We'll see why you need *N/3* guards at most and how this relates to cutting polygons into triangles.
