How many crossing changes does it take to untie a knot? Which 3-manifolds have simple descriptions? How many different 4-dimensional Euclidean spaces are there? We will give context for such questions and provide some answers using a tool called Heegaard Floer homology. This is joint work is S. Eli, C. Karakurt, T. Lidman, and J.
