This is an expository talk. Large scale geometry ignores small scale phenomena. We will explore some highlights. Curvature is an infinitesimal property of Riemannian metrics but it has large scale implications. Negative curvature implies geodesics fly apart quickly. This idea can be generalized to metric spaces that are not even connected: Gromov hyperbolicity and delta-thin triangles.
