Gordon Lecturer, Dr. Alissa Crans Professor of Mathematics at Loyola Marymount University, will present “Frosting Fairness, Finally!” on Friday, March 24th at 3:30 p.m. in Olin 222.
Many of us are familiar with how to slice a cake ensuring equal sized slices for all. But what about those of us who want an equal amount of frosting as well?! This question is a classic with the problem solvers amongst us. In 1975, Martin Gardner considered a square cake cut into 7 pieces in his Scientific American column. More than a decade earlier, H.S.M. Coxeter posed the problem for a square cake sliced into 9 pieces as an exercise in his book, Introduction to Geometry. Together, we will solve this problem for a square cake cut into 5 pieces, and investigate the other cake shapes for which the same procedure will produce slices with equal cake and frosting.
This presentation is sponsored by the Doris G. Gordon Lecture Series and the Department of Math and Computer Science.
