[EX Q]: Cardinal Thomas Gibbons' defense of this organization would lead to Pope Leo XIII issuing an encylical, Rerum Novarum, supporting organizations of their kind. In contrast with its inclusive reputation, a chapter of this group was involved in the Seattle riots of 1886. Internal feuding following the failed Missouri Pacific railroad strike of 1886, and the emergence of a rival organization of skilled craftsmen, meant that by 1900, this organization was almost nonexistent. Name this labor organization that helped lobby for the Chinese Exclusion Act and, for 10 points, was founded by nine tailors in Philadelphia in 1869 and reached its peak under Terence V. Powderly.
[EX A]: History

[EX Q]: This rule holds if the operator algebra for some set of observables is non-trivial; that is true because it is derived via the Schwarz inequality applied to the expectation value of the commutator of two observables operators. It formally bounds the product of the dispersions in two observables. An adapted form of this law applies to energy and time; it applies directly to any two components of spin, but it is best known in its application to position and momentum, the product of the standard deviations of which is at least h-bar over two. FTP, name this principle from quantum mechanics that limits the precision of measurements.
[EX A]: Science

[EX Q]: In one work by this author, the speaker laments that "passion sometimes would prevail/Nor could to-night's gay feast restrain/A sudden thought of one so pal". This author of "Abt Vogler" wrote another poem in which the title character wishes to be like Agnolo or Leonardo and competes with The Cousin for the love of Lucrezia. In another poem, the title character "talks to his own self, howe'er he please/touching that other, whom his dam called God"; that poem is based on a god worshiped by a certain character fromThe Tempest.Another poem by this author of "Andrea del Sarto" features an image of Neptune taming a seahorse; its narrator laments that the title character disregarded a centuries-old name, and that poem concerns a painting by Fra Pandolf.
