Abstract: For a curve in projective space, the varieties parametrising its secant planes are among the most studied objects in classical enumerative geometry. We shall start with an introduction to secant varieties and explain the role of degeneration arguments in understanding their geometry. We shall then explore the connection between the enumerative geometry of secant varieties and Virasoro algebras on one side, and tautological integrals on the other.
