The MAA endeavors to ensure that all the mathematical sessions at MathFest are accessible to a broad audience and undergraduate students are invited and encouraged to attend any of them. In addition, the MAA provides the following sessions that are aimed specifically at the interests of undergraduate students. Full descriptions of some events are found elsewhere in the program.

## Invited Address

### Pi Mu Epsilon J. Sutherland Frame Lecture

#### The Singular Uniformity of Large Random Systems

*Wednesday, August 1, 8:00 p.m. - 8:50 p.m.*

**Peter Winkler**, *Dartmouth College*

##### Abstract

A random structure could be anything, yet somehow, when that structure is composed of many small parts, it often turns out to be shockingly predictable---at least, in a probabilistic sense. A random graph on a million vertices, for example, has a long list of characteristics each with high probability.

In an attempt to understand this phenomenon, we'll take a little tour from zero-one laws to variational principles, contrasting graphs and permutations along the way.

## Social Event

### MAA-PME Student Reception

*Wednesday, August 1, 4:30 p.m. - 5:30 p.m.*

##### Description

Undergraduate students are invited to come for refreshments and a welcome to MathFest.

## Math Jeopardy

*Wednesday, August 1, 5:30 p.m. – 6:15 p.m.*

##### Description

**Answer:** A fun undergraduate mathematics contest to lead off MathFest.

**Question:** What is Mathematics Jeopardy?

Four teams of students will provide the questions to go with the mathematical answers in many categories. All interested students in the audience can enter their names to be chosen to play on one of the four teams of four players. There will be prizes for all the participants.

Come cheer for your favorite team. The session will be emceed by Michael Berry.

### FAIL: A Mathematician's Apology

*Thursday, August 2, 1:30 p.m. - 2:20 p.m.*

**Laura Taalman**, *James Madison University*

##### Abstract

The job of being a mathematician primarily consists of long periods of failure punctuated by short bursts of success which later seem to be somewhat obvious...but that’s what we love about it! And, as it turns out, 3D printing kind of works the same way. In this talk we’ll take a journey through many mathematical and 3D printing failures and try to laugh about it the best we can.

##### About the Speaker

Laura Taalman is a Professor of Mathematics at James Madison University whose research has included algebraic geometry, knot theory, and games. Dr. Taalman also publishes Calculus textbooks and Sudoku puzzle books, blogs at Hacktastic and Shapeways, and designs and shares hundreds of models with the 3D printing community, where she is known as “mathgrrl”. She consults for 3D printing companies as an “expert amateur”, a completely real thing which here means “a person who is good at doing things that they aren’t particularly good at.” Dr. Taalman is a Project NExT Fellow, a recipient of the Alder Award, Trevor Evans Award, and SCHEV Outstanding Faculty Award, and has been featured on Thingiverse, Adafruit, and Science Friday.

## Undergraduate Student Activity

### The Case of the Missing Vertex

*Friday, August 3, 1:30 p.m. - 2:20 p.m.*

##### Description

A vertex has gone missing in an un-labeled graph and taken all of its edges with it. Can we reconstruct the original graph, or at least some of its properties? What if we have the vertex-deleted graph for each of the vertices? Come join this mathematical investigation of the Graph Reconstruction Problem. This fanciful activity provides an introduction to Graph Theory and leads to an open question in the research. Bring a friend and writing utensil.

##### About the Speaker

Suzanne Dorée is Professor of Mathematics and chair of the Department of Mathematics, Statistics, and Computer Science at Augsburg University in Minneapolis where she has taught since 1989. She earned her Ph.D. in Character Theory from the University of Wisconsin-Madison. Her research interests include curriculum and materials development and directing undergraduate research in graph theory. She enjoys teaching mathematics at all levels using pedagogies that support active and inquiry-based learning. An avid gardener, cook, and designer, she appreciates the importance of getting her hands dirty, and not just in mathematics.

**Suzanne Dorée**, *Augsburg University*

## Panel Session

### Nonacademic Career Paths for Undergraduate Mathematics Majors

*Friday, August 3, 3:00 p.m. – 4:20 p.m.*

##### Description

You’re about to earn a degree in mathematics. Now what? You may be surprised to know that teaching isn’t your only option; in the “real world,” mathematical knowledge is a valued commodity, and there are many interesting job opportunities for mathematicians in nonacademic settings. Whether you are a mathematics student looking for a job once you graduate or an advisor looking for advice to give to future job-seeking students, this session will help you gain new perspectives on nonacademic career experiences and what employers value in their employees. Panelists will share their paths to their current positions and offer advice to others looking for employment in similar venues.

**Organizers:**

**Pamela Richardson**, *Westminster College*

**Violeta Vasilevska**, *Utah Valley University*

**Erin Valenti Bawa**, *Monticello Associates*

**Stephanie Fitchett**, *Transamerica*

**Emilie Purvine**, *Pacific Northwest National Laboratory*

**Tyler Rust**, *Fast Enterprises*

## Estimathon!

*Thursday, August 2, 4:30 p.m. – 6:15 p.m.*

They're called Fermi problems...

How heavy is the Eiffel Tower?

How many prime numbers have distinct digits?

How many calories would you be eating if you had "one of everything" at the Cheesecake Factory?

If you're looking for a mindbending mixture of math and trivia, look no further! Jane Street Capital presents The Estimathon contest: teams will have 30 minutes to work on 13 problems, ranging from totally trivial to positively Putnamesque. Can your team beat the all-time best score?? The top teams will receive prizes!

As in past years, we will run 2 contests. Feel free to show up to either one!

(Please show up 15 minutes before the start time of the contest you want to join.)

Our target schedule is as follows:

3:30 p.m. Welcome, overview of rules and scoring

3:45 p.m. Estimathon contest #1

4:30 p.m. Estimathon contest #2

About 20,000 teams, each consisting of three undergraduates, entered the 2018 Mathematical Contest in Modeling in February. Teams chose one of two real-world problems. Teams have four days to deal with the MCM challenge and may use or access any inanimate source – computers, libraries, the Web, etc. MAA judges choose a winner for each problem. The two MAA winning teams of students will present their results of the MCM four-day challenge.
