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:
The magnetic moment of a charged particle is equal to this quantity times the g-factor times charge divided by two times the mass. Delta baryons have a value of 1.5 for this quantity, and, like other particles with half-integer values of this quantity, obey Fermi-Dirac statistics, whereas those with integer values obey (*) Bose-Einstein statistics. The Pauli Exclusion Principle states that pairs of electrons in the same orbital sub-shell must have opposite values of this quantity. For ten points, identify this quantum number, the angular momentum of a sub-atomic particle.

Ex Input:
Mobility is related to the zeta potential, dielectric constant, and this quantity in the Smoluchowski equation. For gases, the variation of this quantity with temperature is given by Sutherland's formula. Measured with a Zahn cup, this quantity is squared in the Grashof number, and the ratio of this quantity to thermal diffusivity is the Prandtl number. When this quantity is zero, the Euler equations correspond to the NavierStokes equations. Reynolds number is the ratio of inertial forces to this quantity, which is constant for Newtonian fluids. Measured in poise [PWAHZ], this quantity is zero for superfluids. For 10 points, name this internal friction of a fluid that tends to resist its flow.

The CIZA project determined that it only has 10% of its originally postulated mass, while Bertschinger and Dekel calculated the maximum Sachs-Wolfe anisotropy due to its effects. Partly responsible for the dipole anisotropy, it was originally discovered by a group later dubbed "The Seven Samurai". This structure is associated with a filamentous redshift phenomenon known as the Fingers of God. It was found due to irregularities in the Tully-Fisher relationship, resulting in peculiar velocities of up to 700 kilometers per second in several galaxies, and it contains the Norma and Abell 3627 cluster. It lies directly in front of the Shapley Supercluster and is core is located in giant filament of dark matter called the Great Centaurus Wall. Located in the Zone of Avoidance, for 10 points, name this object 250 million light-years across, named for its tendency to pull galaxies toward it.
