A fundamental problem in algebraic geometry is to find rational parametrizations for the solutions of a polynomial equation--or demonstrate that such a parametrization is impossible. Such parametrizations are useful in many fields, from mapmaking and computer-aided design to number theory. The goal of this talk is to summarize very recent progress on these questions due to Voisin and others, while highlighting remaining outstanding open questions.
