Josef Stefan was an Austrian physicist and mathematician of Slovenian ethnicity who discovered the Stefan-Boltzmann Law, which states that the energy radiated by a black body is proportional to the fourth power of its absolute temperature. He also made contributions on topics such as heat conduction, diffusion, evaporation, and phase transitions. Learn more about his life, discoveries, and legacy.
