What the article says around this equation
Pull a molecule apart with an optical trap or an atomic force microscope and record the work done. Repeat the pull hundreds of times under identical conditions and the recorded work values scatter — sometimes wildly — because thermal noise contributes to every individual trajectory. That scatter looks like it should make the equilibrium free-energy difference F unrecoverable from irreversible, far-from-equilibrium pulls.
