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: 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.

Output: Science


Input: Consider 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.

Output: Science


Input: Consider Input: In the beginning of this novel, people in an auditorium listen to the wild music of Scriabin as an example of primitive irrationality. Set in an indeterminate future after the Two Hundred Years War, this novel also describes a riot caused by thousands of people casting dissenting votes during the Day of Unanimity. Its protagonist, a mathematician in charge of building the spaceship Integral, writes For Reason must prevail after he undergoes a forced operation to remove his imagination, which causes him to betray his revolutionary friends to the Benefactor. Written as the diary of D-503, one of the many Numbers that make up the One State, FTP, identify this dystopian novel by Yevgeny Zamiatin.
