Abstract
Topology illuminates properties of geometric spaces which are independent of scale. Scale-independent features of physical systems play an important role, for example when deducing the large-scale behavior from a small-scale description. After an introduction to basic topological ideas, I will discuss two joint results with Mike Hopkins, one an application to string theory and the other an application to condensed matter theory.
