The disk embedding problem is of fundamental importance in the study of 4-dimensional topology.  I will discuss its significance and difficulty, including how disk embedding makes dimension four intrinsically different from other dimensions.  Then I will present some recent advances toward the existence and non-existence of embedded disks in 4-manifolds.
