For 10 points, name this scientist whose eponymous constant is symbolized with a lower-case h.
This man resolved the "ultraviolet catastrophe" by introducing his namesake law of radiation, which describes the electromagnetic radiation of all wavelengths at any temperature. In a hydrogen atom, angular momentum is quantized in units of the reduced form of his constant. In quantum mechanics, his law describes the direct relationship between a photon's energy and its frequency.
