To solve the ultraviolet catastrophe, he posited that radiation has discrete allowed energies or quanta given by n times v times his namesake constant.
This man sometimes names the earliest epoch, when quantum gravitational effects were significant. A 2009 mission attempting to map the CMB was named for this man. This man also names a hypothetical, subatomic black hole whose Compton wavelength is equal to its Schwarzchild radius. The Langevin equation, a stochastic differential equation, is used with the Chapman-Kolmogorov identity to derive a partial differential equation describing the time evolution of the probability (*) density function that is named after Fokker and this man. This man's law is approximated at low frequencies by the Rayleigh-Jeans law and accurately describes the intensity radiated by a black body. To solve the ultraviolet catastrophe, he posited that radiation has discrete allowed energies or quanta given by n times v times his namesake constant. For 10 points, name this German physicist.
