We will discuss questions about the relation between discrete phenomena and their continuous counterparts. This relates to extension of partially defined functions, Bourgain’s work on discretization and almost extension for a quantitative version of Ribe’s rigidity theorem, and differentiation questions that are well understood as infinitesimal phenomena but their macroscopic counterparts remain basic mysteries.
