Input: Consider Input: One of this man's theories was supported by the discovery that Hittite contained forms in which distinct reflexes of the laryngeals are recorded, and he explained how the vowel alternations of a came about in his first work, Memoir on the Original System of Vowels in the Indo-European Languages.

The work he is most famous for is often considered the foundation for structural linguistics, though Charles Bally and Albert Sechehaye actually published it. FTP name this Swiss linguist whose lecture notes and other materials were posthumously turned into the seminal Course in General Linguistics.

Output: Social Science

Input: Consider Input: Pausanias claims that one member of this profession, an Euboean son of Crius, is the source of an alternative tradition for the name of Pythos. In the Homeric Hymn to Demeter, Demeter pretends to be Dosos, a person wronged by people in this profession.

Input: Consider Input: The Wigner D-matrix satisfies a number of differential properties if space-fixed operators of this quantity are introduced and the summation of this quantity can be governed by using Clebsch-Gordon coefficients. In quantum mechanics, the spherical harmonics are eigenfunctions of this quantity and they obey a commutation relation equal to I times h-bar times this quantity in the mutually (*) orthogonal direction. The time derivative of this quantity is equal to torque and its conservation is demonstrated in Kepler's Second Law. Planck's constant has the dimensions of, FTP, what conserved quantity symbolized L and defined as the cross product of a position vector and linear momentum.
