Title: The Math of Mapmaking

Abstract:  Have you ever wondered why the same piece of land can look different in different maps of the Earth? This is not just carelessness on the part of mapmakers! A sphere and a plane have different curvature, so Gauss’s Theorema Egregium tells us that they are not isometric. This means that there is no way to make a flat map of the Earth that preserves all distances. Instead, mapmakers often try to preserve other metric properties like area, local shape, or direction. In my talk, I will discuss the Theorema Egregium and some of the math involved in different map projections.
