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: This quantity for an atomic nucleus is determined using Weizscker's [VAHYTS-zek-uhrs] formula. The no hair theorem states black holes are completely characterized by their angular momentum, charge, and this quantity. The oscillation period of a spring equals two pi times the square root of this quantity over the spring constant. The theoretical value of this quantity for gluons is zero. Linear momentum equals this quantity times velocity. For 10 points, name this quantity measured in kilograms.

Output: Science


Input: Consider Input: In one of his paintings, two men in green and orange hold hats in one hand and staves in the other, while a bearded man in white carrying a backpack goes hiking. Another of his paintings shows a storm raging as the titular animal takes an s-shaped curvature. Other than The Meeting and The Fox in the Snow, this artist also painted a nude woman lying on a white cloth with her raised left arm holding the title creature in Woman with a Parrot. The Shaded Stream and The Hammock are forest scenes reminiscent of his painting of a dead deer hung from a tree while a man plays a horn, The Quarry. In addition to Les demoiselles de village, he also painted a hairy closeup of a woman's genitals in The Origin of the World, and a nude woman standing behind the painter himself working on a landscape in The Artist's Studio. Known for painting a funeral in his hometown, FTP name this artist of Burial at Ornans.

Output: Fine Arts


Input: Consider Input: An extraordinary form of this behavior exists in systems for which the double exchange mechanism is energetically favorable, as exemplified by Heusler cells. Two important tools for studying systems with this property are a chart that has the as its x- and y-intercepts the coercivity and remanence, respectively, and a lattice model with Hamiltonian given by the sum over cells of the product of two numbers from U one, one number for the cell and one for each of its neighbors. Materials displaying this property exhibit near-constant H-fields on structures separated by Nel or Bloch walls and known as Weiss domains, which break down at the Curie temperature. For ten points, identify this form of magnetism studied with the aforementioned hysteresis loops and Ising model and materials displaying which retain a permanent magnetization when placed in an external field.
