I’m not exactly sure how I ended up finding this great example of solving a topological problem. In May, The Consumerist reported that after three years of protest, Subway will stop the madness of unnecessary dairy overlap and require employees to flip half of the cheese slices to improve the coverage and taste of its sandwiches. Really, where else would you ever see the words “tessellate” and “cheese” in the same sentence?
