Math Horizons Contents—November 2017

Math Horizons November 2017 Cover

Congressional gerrymandering is currently a hot-button topic that has been the subject of news articles, court cases, and . . . mathematics seminars. Yes, Temple University mathematician Moon Duchin has been on the front lines, encouraging mathematicians to look at the mathematics of drawing the boundaries of congressional districts. In our cover story, Duchin chats about this work and her view that, contrary to what G. H. Hardy wrote, mathematicians want to get involved in outreach.

Also, in this issue, Jim Propp discusses his use of geometry and symmetries to create fair teams at his son's paintball birthday party. Ray Rosentrater discusses how mathematics can be used to identify possible cases of fraud. And Lawrence Brenton describes the surprising appearance of geometry in religious rituals throughout history and around the globe. Enjoy these articles and more in the November issue of Math Horizons. —David Richeson, Editor

Volume 25, Issue 2
