Question: sum of the squares of the reciprocals of this function evaluated at the nonnegative integers is equal to the modified Bessel function of the first kind at x=2. The Leviathan Number is found by evaluating this function at 10 to the 666th power. The rising type can be represented with the Pochhammer Symbol. Wilson's Theorem states that this function of any prime minus 1 is also congruent to -1 modulo that prime. Legendre's theorem provides a corollary to determine the number of (*) trailing zeroes of this function evaluated at nonnegative integers. When this function is evaluated at large numbers, Stirling's approximation is used. The gamma function extends this function to all complex numbers other than negative integers. For 10 points, name this function that, for positive integers n, is the product from 1 to n, and which is represented by an exclamation point.

Answer: Science

Question: 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. He is noted for his terms langue, or regularities and patterns in speech, and parole, or actual acts of speech. 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.

Answer: Social Science

Question: Thomas Tatton claimed that there was a crowd of only thirty thousand people at this event, while James Wroe, in the Observer, gave the highest estimate at 153 thousand. Wroe and Richard Carlile were imprisoned for publicizing the story of this incident, which inspired Percy Bysshe Shelley to write The Masque of Anarchy. Samuel Bamford was also imprisoned after this event perpetrated by the 15th Hussars and the Cheshire Volunteers, and Home Secretary Sidmouth responded by proposing the Six Acts. The trouble began when Henry Hunt was arrested and prevented from speaking, and eleven people were killed when cavalry troops overwhelmed the demonstrators in Manchester. FTP, name this 1819 incident, with a name reminiscent of Napoleon's final defeat.
