Mathematics Makes Communication Possible

Wednesday, January 17, 2018, 6:00pm

Blocker 117

Reception 5:30-6 pm, discussion 7-7:30 pm
Everyone is welcome!

Abstract: How do we ensure security in internet communications, for example, when using a credit card to make an online purchase?  How do we efficiently transmit or store data, such as satellite pictures from outer space or music on a CD or an iPhone, in such a way that we can reliably read that data even in the presence of noise, such as electronic interference or a scratch or dust?  In this talk, we will see that the answers to both of these questions hinge on beautiful mathematics that was once thought to be too abstract to be of any practical use. 

Judy L. Walker is Aaron Douglas Professor for Teaching Excellence at the University of Nebraska–Lincoln. She has served as chair of the department of Mathematics as well as Associate Vice Chancellor for Faculty and Academic Affairs at the university. She is the co-founder of the Nebraska Conference for Undergraduate Women in Mathematics and the All Girls/All Math program for high school girls. She has received the Louise Hay Award for Contributions to Mathematics Education from the Association for Women in Mathematics in 2016, and was the Mathematical Association of America George Pólya Lecturer in 2009-2011. She is a fellow of the American Mathematical Society.

The Sue Geller Undergraduate Lecture Series is intended as a venue for undergraduate students to interact with a leading researcher from outside Texas A&M University who has also demonstrated a deep interest in mentoring students. Before 2018 it was known as the Mathematics Undergraduate Research Lecture Series. The 2016 speaker was Richard P. Stanley from MIT, the 2017 speaker Jeffrey C. Lagarias from the University of Michigan.

Sue Geller, known to students as Dr. Sue, is Professor of Mathematics at Texas A&M. She was the founder and long-time Director of Honors in Mathematics, the first department-level honors program at TAMU. She has supervised more than 100 Masters students and has mentored an uncountable (although finite) number of undergraduates. Her honors include the Ron Barnes Distinguished Service to Students Award from the Texas section of the Mathematical Association of America, and the Texas A&M University Distinguished Service Award in Individual Student Relationships.
