	Joseph Stefan - Wikipedia, the free encyclopedia
		Joseph Stefan (Slovene Jožef Stefan) (March 24, 1835 – January 7, 1893) was a Slovene-Austrian physicist, mathematician and poet.
		Stefan was born in an outskirt village St.
		Stefan provided the first measurements of the thermal conductivity of gases, treated evaporation, and among others studied diffusion, heat conduction in fluids.

		The Austrian physicist Josef Stefan made important contributions in the fields of acoustics, electromagnetism, optics, and the thermal sciences, and is the eponym of an important scientific constant, a physical law, and a series of dimensionless variables.
		Josef Stefan was born March 24, 1835, in the small village of St. Peter, just outside the town of Klagenfurt.
		Stefan was personable and outgoing, a well-liked teacher and administrator, but very focused on his work, so much so that he had few friends outside of the institute and almost no social life.

	Ludwig Boltzmann
		In contrast of his revered teacher Josef Stefan and to his older, beloved frie nd, the remarkable physicist and chemist Josef Loschmidt, he did not have to work his way up from village poverty to a university position.
		He did not have to help illiterate parents on their farm like Stefan, nor did he have to tend cattle in his youth and then earn his way by tutoring and by working as a factory chemist like Loschmidt.
		After working with Stefan for two more years he was appointed the Professor of Mathematical Physics at the University of Graz in the province (Kronland) of Styria.

		Josef Loschmidt, a pioneer of 19th-century physics and chemistry, deserves to be better known in the English-speaking world.
		At the urging of Josef Stefan, he was given a faculty position at the University of Vienna in 1866.
		By contrast, Stefan, Maxwell, Boltzmann, and other leading physicists were very receptive to Loschmidt's determinations of molecular size and mass, and to his later work in physics.

	Stefan, Josef
		His law was one of the first important steps toward the understanding of flbody radiation, from which sprang the quantum idea of radiation.
		At the University of Vienna, Stefan rose from lecturer in mathematical physics in 1858 to professor ordinarius of physics in 1863 and to director of the Physical Institute in 1866.
		Five years after he derived his law empirically, it was derived theoretically by Ludwig Boltzmann of Austria and hence became known as the Stefan-Boltzmann law.

		A breakthrough occurred when it was realized that even though a theory describing the radiation emitted from a hot object is difficult to construct without a microscopic knowledge of the exact processes involved, considerable progress can be made using the general principles of thermodynamics coupled with Maxwell’s predictions for the radiation pressure of electromagnetic radiation.

		By placing all but one of his actors under hypnosis, Herzog achieved his desired effect, eliciting performances that seem oddly detached and trancelike, perfectly appropriate to a story about 19th-century Bavarian villagers who have lost their collective vision, cast adrift and descending into madness.
		They've lost the life-sustaining secret to the magical ruby-red glass that was once made in the local glassworks, and their predicament cannot be solved by the mystic (Josef Bierbichler, the only actor not hypnotized) who appears with premonitions of the fate of all humankind.
		All of this is mere pretense for Herzog's loftier (and not altogether successful) ambition: to present haunting, mysterious images that seem directly drawn from our collective subconscious.
