### Abstracts and Bio

Sarah J. Greenwald is Professor of Mathematics and
Faculty Affiliate of Gender, Women's and Sexuality Studies at Appalachian State University.
Her PhD in mathematics is from the University of Pennsylvania in Riemannian geometry. She investigates connections between mathematics and society, such as women, minorities,
and popular culture.
She has won several awards for teaching, scholarship and service, most recently a 2018 Association for Women in Mathematics Service Award.
These also include a 2005 Mathematical Association of America Alder Award
for distinguished teaching
and the winner of the
2010 Appalachian State University Wayne D. Duncan Award for
Excellence in Teaching in General Education.
In 2010 she was also inducted into the Appalachian State University College
of Arts
and Sciences Academy of Outstanding Teachers and
in 2011 she was named the College of Arts and Sciences Outstanding Teacher of the Year.
She is the associate editor of the
Association for
Women in Mathematics Newsletter
and a member of the editorial board of PRIMUS. She
co-created the educational website SimpsonsMath.com with Andrew
Nestler. While it is not affiliated with the show, the site was mentioned
in the audio commentary of the 7th season of *The Simpsons*. Her
interactive mathematics lecture
has been distributed on approximately one million DVDs worldwide
as a 25-minute DVD extra for the
20th Century Fox *Futurama* movie *Bender's Big Score*
and it is listed as "Mind-bending." She co-edited the 3-volume
*Encyclopedia
of Mathematics & Society*, which was named a
"Best Reference 2011" by *Library Journal*,
and the 2018 Springer volume *Women in Mathematics: Celebrating the Centennial of the Mathematical Association of
America*.
Dr. Greenwald has spoken about the impacts of scientific popular culture
representations on NPR's Science Friday and all over the country.

### Good News Everyone! Mathematical Morsels from *The Simpsons* and
*Futurama*

Did you know that *The Simpsons* and *Futurama*
contain hundreds of humorous mathematical and scientific references?
What curious mathematical object is used as a bottle for beer in the
31st century? What happens when Homer tries to emulate Thomas Edison?
What is the significance of the number 1729? The only
prerequisite for this talk is an open mind, so come
find out!
We'll explore the mathematical content and educational value
of some favorite moments along with
the motivations and backgrounds of the writers during an interactive talk.
Popular culture can reveal, reflect, and
even shape how society views mathematics, and with careful consideration of
the benefits and challenges, these programs can be an ideal source of fun
ways to introduce important concepts and to reduce math anxiety.
In the process we'll look at related, recent work in geometry
and computational number theory so a calculator and writing utensil will
be useful. For more information, check out SimpsonsMath.com.

### Popular Culture and Mathematics: Gender, Race, and more

Mathematics is pervasive in modern society, and on some level we all use mathematics
in our daily lives. Have you ever known anyone who asserted that they do not have the "math gene"? Where do those messages come from? Popular culture can reveal, reflect, and even shape how society views mathematics and mathematicians, and
we'll analyze examples from a variety of shows and films and consider the intersections of gender, race, class, and ability.
For example, *The Simpsons* and *Futurama* contain hundreds of humorous mathematical and scientific references.
We'll also discuss ways to counter stereotypes and to contribute to research in this area.
At the same time we'll reflect more broadly on what mathematics has to offer,
and the diverse ways that people can succeed to make an impact, including you!
### How and Why AWM was Founded, and Why It's Still Needed in the 21st Century

The Fields Medal, Girl Scouts, GoldieBlox, Wikipedia and more?
We'll explore how these relate to the Association for Women in Mathematics
(AWM) and why AWM is needed today. AWM is a non-profit organization that
supports and promotes female students, teachers and researchers. With more
than 3000 members (women and men), AWM represents a broad spectrum of the
mathematical community - from the United States and around the world. While
AWM was celebrating its 40th anniversary in 2011, I was beginning to research
the history of the organization. We'll look back at how and why AWM was
formed as we learn about the active role it continues to play in the lives
and work of girls and women.

### Geometry of the Earth and Universe

The quest to understand the precise geometry and shape of our universe
began thousands of years ago, when mathematicians and astronomers used
mathematical models to try and explain their observations. We'll explore
historical and current theories related to the geometry of the earth and
universe during an interactive talk.
A globe or child's ball will be useful.
### Rubik's Cube Games on Spheres: Geometry of Spherical Orbifolds

We'll slice up basketballs in order to form new spaces like footballs and
triangular pillows, and then look
at the geometry of the resulting spaces, called orbifolds. Orbifolds
furnish a natural starting point for the study of singular spaces and
they are especially of interest to mathematicians and physicists.
Diverse applications of orbifolds include connections to crystallography,
string theory and music theory.
Many results,
such as those requiring local analysis, generalize easily to the
orbifold setting, but most global results do not. Imagine a
spherical Rubik's game where you can rotate spherical triangles on
the surface of the sphere. This game exists and is called the Impossiball and
we'll use it to
help understand orbifolds, as we look at lots of examples and results
related to the diameter, Euler characteristic, and spectrum.
This talk is aimed at students interested in mathematics or physics who have
taken linear algebra or multivariable calculus.
