Named for the British physicist whose double-slit experiment showed that light is a wave, for 10 points, name this elastic modulus describing the ratio of stress to strain in a material.
For a homogeneous, isotropic material, this quantity is given by three times quantity one minus two times Poisson's ratio, all over the compressibility. When a certain criterion holds, resilience can be defined as one over twice this quantity times the square of yield stress. Like pressure, it is measured in Pascals, and according to the generalized Hooke's law, this quantity is equivalent to the slope of a material's stress-strain curve.
