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. The first two talks will be in Savery Hall room 260 and the third will be in Gowen 301.

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 talks.

We will discuss how studying the path of a ball bouncing around a square room connects to the study of fractions and the study of grid patterns. The talk will be elementary and showcase connections between geometry, algebra, and number theory. Lots of pictures and patterns!

**The Life, Legacy, and the Lost Library Books of Leonhard Euler**

April 15 is the birthday of Leonhard Euler – one of the greatest and most prolific mathematicians in history. This talk will examine the life of Euler, and will discuss some of his major accomplishments, in fields ranging from number theory to geometry. We will also tell stories of the speaker's role in creating the online “Euler Archive” and of the fascinating old books by Euler he discovered in several libraries.

**Stable Matching**

Video Recording

In 2012, a Nobel Prize in Economics was given in part for the solution to the following problem: Say we have 100 boys and 100 girls and we want to make them into couples. Everyone makes a list of their ideal partners from 1 to 100 in order of most favorite to least favorite. The question now is whether there is a way to match everyone up so that the matching is “stable”: This means that there is no couple (A,B) in our matching where girl A prefers some other boy to B and boy B prefers some other girl to A.
In this Math Hour, you will learn about an efficient algorithm for solving this problem and the fascinating properties of stable matchings.
