The problem of constructing flat representations of spherical surfaces arises naturally in geography and astronomy while making maps of the earth and sky respectively. We look at a mathematical formulation of this problem using the notion of conformal mapping and discuss its relation with complex analysis. After reviewing the contributions of Gauss, Riemann, and Poincaré to this problem, we end with some glimpses of 20th century developments.

Refreshments precede the talk at 3:30 p.m. in NH 282.
