Title: Uncountable abelian groups that want to be free
Abstract: The title refers to those abelian groups whose failure to be free is caused by set-theoretic rather than algebraic issues. An easy example is the group of infinite sequences of integers (with the operation of componentwise addition). I plan to use the theory of such groups, in particular questions about how far they are from being free, as a motivation for giving quick glimpses of some of the main areas of contemporary set theory.
