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.

Ex Input:
By averaging this quantity, the reduction of a certain intermolecular function to an angle-independent form for polar fluids can be performed in order to express conformal-solution theory. For liquid metals, the upper bound of this quantity can be obtained by the Gibbs-Bogoliubov inequality. It is equal to the negative product of Boltzmann's constant, temperature, and the natural log of the partition function. The change in this quantity is equal to the maximum work accompanying a process, and it is defined as internal energy minus the product of temperature and entropy. For 10 points, name this quantity symbolized by either A or F, a type of free energy named for a German scientist.

Ex Output:
Science

Ex Input:
Instead of employing the Debye-Hull-Scherrer powder method, its namesakes relied on an array of atomic planes. Its namesakes built a vacuum apparatus and employed a hot filament, an accelerating electrode, and an arc-mounted Faraday box. A leak in the vacuum led its namesakes to heat the target, resulting in crystallized nickel, which gave startling results. A plot of collector current against beam energy was explained by constructive interference, and the results in general could be derived by combining Bragg's equation with the de Broglie wavelength for electrons. FTP name this experiment named for two physicists, which proved that electrons diffract.

Science

Ex Input:
Children of this god include Enbilulu, the lord of canals, and Ninazu, the lord of healing, and this god's wife bears the epithet "Lady of the Air". This god raped that wife to produce his first-born child, Sin the moon god. After this god was banished to the underworld he fathered Nergal. According to the legends of Nippur, where this god had a sacred gate, this god's servant was the son of Siris; that servant, the winged demon Anzu, is slain by this god's son, the heroic Ninurta, after stealing the Tablets of Destiny from this god. For ten points, name this Mesopotamian god of winds and lord of storms.
