"Inhomogeneous Electron Gas" written by Hohenberg and Walter Kohn which discuss how the equilibrium state of interacting electrons can be modeled with just electron density (3 dimension) and doesnt need the full electron state (3xN dimension). This is an extrordinary result that is so simple to follow that its crazy it took almost 6 decades of discovery if quantum theory to identify this. The work provided an elegant and tractable way to model complex chemisry and a lot of physics. Most of molecular level modeling that cuts across electronics, energy and pharma are based on this work.
