## The Mathematics of Coral Reef Health

Assistant Professor Julie Blackwood, together with her summer research students and collaborators from Bennington College use mathematics to investigate the deterioration of coral reefs in the Cayman Islands and possible solutions to this problem, including the reintroduction of sea urchins. More information about their work can be found in the following feature story recently published

## Blended Upper Level Math Classes

In September 2016, a team of mathematics faculty, technologists and instructional designers from six leading liberal arts colleges (LACOL member schools Amherst, Haverford, Pomona, Swarthmore, Vassar and Williams) are launching a new collaboration to explore blended course sharing for select topics in advanced mathematics. The goal of the project is to experiment with models for

## SARS at Williams – let’s hope not.

by Prof. Lauren Childs Imagine a SARS outbreak in quaint Williamstown – that’s exactly what Varun Bhadkamkar ’17, Anthony Brooks ’16, Jack Ferguson ’17, Connor Mulhall ’17, and Annie Sher ’17 did in their Math 307 final project. The SARS group built a network model of the Williams College undergraduate population, grouping individuals by dorms

## The Banach-Mazur Game by John Damstra

This spring, I presented my senior colloquium on a topological game called the Banach-Mazur Game. This game was formulated by Stanislaw Mazur in 1935. It is the earliest example of an infinite game with perfect information. The game proceeds as follows. Continue reading. . John Damstra is a senior mathematics major at Williams College.

## Interview with Eyvindur Ari Palsson

Our very own Professor Palsson was featured on the show Meet & Potatoes on WilliNet, the community television for Williamstown. During the show a number of topics were covered including several mathematical in nature. Professor Palsson gave a shout out to the weekly Math Puzzle Dinners – come try them on Wednesday evenings at 5:30 PM
