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.
Example: In one work this author details the life of a tomb-maker who makes extra money by playing the organ at an insane asylum, while another of his novels sees Swartz give a refugee proper documentation only after he tells him his life story in the title Portuguese city. In addition to The Black Obelisk and The Night in Lisbon, he also wrote about Robert and Otto selling their auto workshop and visiting Patrice in a Swiss tuberculosis sanatorium in his novel The Three Comrades, while the turbulent life of the German surgeon Ravic is told in The Arch of Triumph. Another of his novels, The Road Back, is thought to be a sequel to his most famous book, in which the patriotic teacher Kantorek convinces Paul Bumer and his friends to join the Germany Army during World War I. For 10 points, name this German author who wrote All Quiet on the Western Front.
Example solution: Literature
Example explanation: The text is talking about an author and their works, so it belongs to theliterature category.

Problem: quantity is constant in the body frame of an object, but has a time dependence in the space frame given by the position times this quantity in the body frame times the inverse of the position. For a random object, finding this quantity involves taking the integral of an outer product. Half of the time derivative of this quantity is equal to the scalar virial. This quantity provides the coefficients of the axes in Poinsot's ellipsoid. Euler's equations has this quantity in a dot product with the time derivative of angular velocity. The products of this 2nd order symmetric tensor form the non-diagonal term in the tensor matrix while the principal ones of this tensor form the diagonal in the tensor matrix. Given this quantity for one axis, one can find it for another axis with the Parallel Axis theorem. For 10 points, name this quantity that for a hoop is one-half times mass times the radius of gyration.
Solution: Science
