In 1911, Toeplitz asked whether every Jordan curve in the plane contains the vertices of a square.  I will explain why this naïve-looking problem is interesting and so difficult to solve.  Then I will discuss recent progress on it using symplectic techniques, specifically Floer homology, and which seem poised to say much more.  This work is joint with Andrew Lobb.
