Infinite Horizons Lecture Series (IHLS)

Kennesaw Women in Mathematics (KWIM) logoThe Infinite Horizons Lecture Series (IHLS) is sponsored by the Kennesaw Women in Mathematics (KWIM) Student Organization and the Department of Mathematics. Special funding is received to host invited speakers, giving talks aimed at a more general audience, not just upperclassmen and faculty. IHLS talks and events do not follow a regular set schedule; they can be held at any day/time depending on the travel and availability of the speaker.

Spring 2018

Monday, March 19, 2018

  • SPEAKER: Dr. Kim Ruane, Tufts University
  • TITLE: "Linear Algebra in the Real World"
  • WHEN: 4:00-5:00pm, followed by a reception
  • WHERE: Wilson Student Center, Ballroom B (Marietta Campus)
  • ABSTRACT: After telling you a bit about my days at KSU and how I ended up where I am today, I will discuss some applications of Linear Algebra that I like to cover when I teach this class for undergraduates. The main one I will focus on is the connection between Linear Algebra and the Page Rank Algorithm used by search engines such as Google. There is a very simple idea behind page rank and it uses elementary ideas from Linear Algebra and Graph Theory. Of course, the implementation of this simple idea is much more difficult but the linear algebra behind the basic principle is something we teach in a first year Linear Algebra course. I tend to present applications of linear algebra as soon as I start to see the students freaking out over the abstraction they are faced with in the course!

  • SPEAKER: Dr. Moon Duchin, Tufts University
  • TITLE: "Gerrymandering, geometry, and the shape of fairness"
  • WHEN: 12:30pm, followed by a reception
  • WHERE: Wilson Student Center, Ballroom A (Marietta Campus)
  • ABSTRACT: By controlling the shapes of voting districts, you can often predetermine the outcomes of elections. I'll try to convince you that geometry — from high-school geometry to new ideas at the research frontier — can help detect vote-rigging and promote democracy.
  • BIO: Moon Duchin is an associate professor of Mathematics at Tufts University and is the founding director of Tufts' new interdisciplinary Program in Science, Technology, and Society, which spans scholarly approaches to putting science in social context. She has degrees in math and women's studies and a long-standing interest in the history, philosophy, and anthropology of science. In math, her work is in low-dimensional geometric topology, geometric group theory, and dynamics. She lectures widely on her research and engages in educational outreach to all ages of students, with a particular focus on broadening participation in mathematics. She has a PhD from the University of Chicago, a CAREER grant from the National Science Foundation, and was named a Fellow of the American Mathematical Society "for contributions to geometric group theory and Teichmüller theory, and for service to the mathematical community". Well known before, Dr. Duchin became sort of math celebrity after an article in Chronicle about her work to tackle gerrymandering (part of which she will present during her talk), and after announcing a summer school on the subject Read more about Professor Duchin: or

Monday, November 7, 2016

  • SPEAKER: Dr. Victoria Powers, Emory University
  • TITLE: "Proportional (Mis)representation: The mathematics of apportionment"
  • WHEN: 4:00 - 5:00pm, followed by a reception
  • WHERE: Rotunda Lobby, L.V. Johnson Library (Marietta campus)
  • ABSTRACT: Following the 2010 census, Georgia gained a seat in the U.S. House of Representatives while several states lost a seat. Did you ever wonder how the 435 seats in the U.S. House are divided among the states? This is a problem of apportionment, i.e., turning a set of fractions into integers so that the sum of the integers equals the sum of the fractions.

    In this talk we discuss the mathematics of apportionment and we will discover subtleties and paradoxes that aren't apparent at first glance. We will also look at the history of apportionment in the U.S. House, where we will encounter the first U.S. presidential veto, the Alabama paradox, and other fascinating stories.
