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.

Lin and Shu proposed the density-wave theory to explain how the structure of these entities is sustained. The most accurate method for measuring the distances to distant ones uses a relation between their maximum rotational velocity and absolute magnitude, which is known as the Tully-Fisher method. They are generally blue because of their high content of old stars, and one type of them features arms that emanate from each end of a namesake structure. They have discs like the lenticular type, but contain much more angular momentum than the elliptical type. FTP name these galaxies, some of which are barred, including the Milky Way.

Franz Boas used the example of the Kwakiutl to argue that this mans theory of matrilineal to patrilineal movement was flawed. In a work that included the sections Growth of Intelligence and Growth of Idea and Government, he added four more levels to an idea of Montesquieus, and he also wrote The American Beaver and His Works. His joint work with Ely S. Parker among the Tonawanda Seneca led to The League of the Iroquois, and in his most famous work, he posited savagery, barbarism, and civilization as three stages of societal evolution. FTP, name this anthropologist and author of Systems of Consanguinity and Affinity and Ancient Society.

The Lorentzian profile due to the natural broadening of spectral lines is due to this statement. Mandelshtam and Tamm used a general observable operator to reformulate an alternative to this statement and other forms of it detail the relation between the phase of the Ginzberg-Landau parameter and the number of electrons in a superconductor. This statement can be viewed as a special case of the Robertson-Schrodinger inequality, and the canonical commutation relation of quantum mechanics can be used to arrive at this relation in its most familiar form. This statement from quantum mechanics comes in energy-time and position-momentum varieties. For 10 points, what statement, named for a German physicist, says that no two non-commuting observables can be simultaneously measured to infinitely high precision
