The classical algebraic geometers considered two varieties to be the same not just when they were isomorphic, but when they were "birationally equivalent," which is a weaker notion. The question of which smooth hypersurfaces are birationally equivalent to C^n is deceptively simple; it has a long history and remains very active today. I will discuss some of this history, with pictures and models as far as possible, and then disccuss some modern techniques and results.
