Program for Sonia Kovalevsky Math Day
NOTE: schedule from SKMD 2019; to be updated.

Please come to Kemeny Hall

9:30 - 10:00

Continental Breakfast

10:00 - 10:15

A "Welcome" by the organizers, followed by a short biographical sketch of Sonia Kovalevsky

10:15 - 11:00

Workshop: Code Girls

Abstract: Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. In this workshop, we will learn some codebreaking strategies and apply them to unlock a sequence of secret messages.

Graduate Leaders:

Samantha Allen and Marisabel Rodriguez

11:00 - 11:45

Plenary Lecture: Build your own polyhedra

Bjoern J. Muetzel, Professor, Dartmouth College

Abstract: A solid where any side is the same regular polygon and that looks the same at each vertex is called a Platonic solid. We find all five Platonic solids and show that there can be only five. Then we look at what happens if we allow for different regular polygons at different sides and explore the Archimedean solids. This talk is interspersed with hands-on activities where we build these solids with geometiles.

11:45 - 12:30

Workshop: The Graceful Tree Problem

Abstract: Imagine you have several circles connected by line segments. Fill the circles with consecutive odd integers. What happens if you subtract the numbers in connected circles? If you fill the numbers in the circles differently, what happens to the differences? In this workshop, we'll investigate this seemingly simple problem which leads to some surprising conclusions.

Graduate Leaders:

Emma Hartman and Lizzie Tripp

12:30 - 1:30

Buffet Lunch

1:30 - 2:15

Workshop: Eulerian Paths

Abstract: Imagine that you are standing on the corner of the Green at Dartmouth, and you want to walk along all of the walkways without walking on the same path twice. How can you do this? Is it even possible? What if you wanted to end your walk in the same place that you started? In this workshop, we will find the answers to these questions in any possible set-up of paths..

Graduate Leaders:

Sara Chari, Melanie Dennis and Alex Wilson

2:15 - 3:15

Panel Discussion: Why study Math?




3:15 - 3:30
