Many curious phenomena for 4-manifolds have their roots in the fact that certain topologically embedded surfaces cannot be smoothed. For example, there exists a topological 4-manifold with intersection form E8, but no such 4-manifold. I will explain why embedding surfaces is a central problem in dimension four, leading up to the groundbreak work of Freedman and Quinn. I will describe recent advances in finding embedded surfaces in 4-manifolds and focus on a collaborative project aiming to make the work of Freedman and Quinn more accessible.
