Contraction algebras are a class of finite dimensional, symmetric algebras introduced by Donovan and Wemyss as a tool to study the minimal model program in geometry. In this talk, I will give an introduction to these algebras, before then going on to describe how an associated hyperplane arrangement (a simple picture) controls something that, for a general algebra, is considered extremely complicated; namely, the entire derived equivalence class of such an algebra.
