In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

Input: Consider Input: Materials with this property can exhibit a noise arising from self-organized criticality known as the Barkhausen effect. The Ising model was originally formulated to study this phenomenon, in which regions become separated by Bloch walls and materials exhibiting this property are frequently subject to hysteretic effects. The anti variety of this property disappears above the Neel point, while this property itself disappears above the Curie point, where the material transitions to paramagnetism. FTP, identify this form of magnetism resulting from the spontaneous alignment of domains, which is present in metals such as nickel and iron.

Output: Science

Input: Consider Input: Published under the pseudonym Johaness de Silentio, this work is believed by analysts to have two distinct themes. First is the "teleological suspension of the ethical," an example of which is God's order that Abraham kill Isaac. From there the author uses the Abraham/Isaac story to come to terms with the end of his love affair with Regine Olsen. The overall story, then, concerns a contrast between the "tragic hero" and the "knight of faith. " FTP, name this 1843 philosophical work by Soren Kierkegaard.

Output: Social Science

Input: Consider Input: This value appears in both terms of the definition of the Lagrange invariant. Whether this value is in the numerator or the denominator of the expression for momentum is the focus of the Abraham-Minkowski controversy. The square of this value minus one all over the square of this value plus two is equal to four pi over three times number of molecules per unit volume times polarizability. The square of this value is equal to one plus a series of terms with B times lambda squared over lambda squared minus C according to the (*) Sellmeier equation. The difference between its ordinary and extraordinary versions gives birefringence. This value is on both sides of a law which relates the angle of incidence to another angle; that law is named for Snell. For 10 points, name this value symbolized n that is used to measure how much light bends when it moves between media.
