I will discuss the notion of derived completions of rings and ring spectra, which exhibit some very interesting behavior, for example when the rings are non-Noetherian.  I will then show that they are directly applicable to the study of algebraic K-theory, with some surprising results relating the representation theory of the absolute Galois groups with Milnor K-theory.
