Wilhelm Wien
Wilhelm Carl Werner Otto Fritz Franz Wienwas a German physicist who, in 1893, used theories about heat and electromagnetism to deduce Wien's displacement law, which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature...

absolute according theory
According to the kinetic theory of gases, the mean kinetic energy of a molecule is a measure of absolute temperature.
field fortunate mainly radiation
If, as is the custom, I speak mainly about my own researches, I must say that I was fortunate in finding that not everything had yet been gleaned in the field of general thermodynamic radiation theory.
almost astute beyond boundaries enter pure region soon
As soon as we step beyond the established boundaries of pure thermodynamic theory, we enter a trackless region confronting us with obstacles which even the most astute of us are almost at a loss to tackle.
certain hot means produce radiation since thus types
Since we can produce all types of light by means of hot bodies, we can ascribe, to the radiation in thermal equilibrium with hot bodies, the temperature of these bodies, and thus every radiation, even that issuing from a phosphorescent body, has a certain temperature for every colour.
