This man's namesake hypothetical particle is a small black hole whose Compton wavelength equals its Schwarzschild radius. He solved the problem of ultraviolet catastrophe present in the Rayleigh-Jeans Law, by developing his namesake law, which describes electromagnetic radiation of a blackbody for all wavelengths. His constant appears in expressions for reaction rate and activation energy in the Eyring and Arrhenius equations, and is defined as a photon's energy divided 
This man's namesake hypothetical particle is a small black hole whose Compton wavelength equals its Schwarzschild radius. He solved the problem of ultraviolet catastrophe present in the Rayleigh-Jeans Law, by developing his namesake law, which describes electromagnetic radiation of a blackbody for all wavelengths. His constant appears in expressions for reaction rate and activation energy in the Eyring and Arrhenius equations, and is defined as a photon's energy divided by its frequency. Other quantities named after him include his namesake length, mass, and time. For 10 points, name this German physicist who discovered the quantization of energy.
