Article: The assumption that black-body radiation is thermal leads to an accurate prediction: the total amount of emitted energy goes up with the temperature according to a definite rule, the StefanBoltzmann law (187984). But it was also known that the colour of the light given off by a hot object changes with the temperature, so that "white hot" is hotter than "red hot". Nevertheless, Wilhelm Wien discovered the mathematical relationship between the peaks of the curves at different temperatures, by using the principle of adiabatic invariance. At each different temperature, the curve is moved over by Wien's displacement law (1893). Wien also proposed an approximation for the spectrum of the object, which was correct at high frequencies (short wavelength) but not at low frequencies (long wavelength). It still was not clear why the spectrum of a hot object had the form that it has (see diagram).

Question: What characteristic of the light emitted by a hot object changes with temperature?
Ans: the colour of the light given off

Article: During the 19th and 20th centuries there was a major dispute known as the Greek language question, on whether the official language of Greece should be the archaic Katharevousa, created in the 19th century and used as the state and scholarly language, or the Dimotiki, the form of the Greek language which evolved naturally from Byzantine Greek and was the language of the people. The dispute was finally resolved in 1976, when Dimotiki was made the only official variation of the Greek language, and Katharevousa fell to disuse.

Question: Which language was considered the language of the people?
Ans: Dimotiki
