Ex Input:
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 Output:
Science


Ex Input:
The development section of this work's first movement quotes the panikhida, and those verbal rhythms return in the second and fourth movements, the latter of which Timothy Jackson theorizes was drawn from the composer's final set of Six Romances for voice and piano. Opening with a low bassoon solo over strings, this work's third movement is a boisterous march-scherzo that features an extended fragmentary introduction of its theme. Other innovations in this work include the five-four time signature of the second movement waltz, while basses playing (*) pianiss-iss-iss-iss-issimo end this piece's quiet finale, an Adagio lamentoso. Premiered nine days before the composer's death, for 10 points, name this final symphony of Pyotr Tchaikovsky.

Ex Output:
Fine Arts


Ex Input:
It attempted to implement such changes as the banning of private property and the shift to a solar calendar, and one theory holds that the game of Mah-jongg was created during it by bored army officers. Its king was eventually dethroned by the Xiang Army led by Zeng Guofan and Zuo Zongtang, a man more famously known as General Tso. Its leader, a member of the Hakka ethnic group, added a third book to its official Bible. FTP, name this rebellion whose leader, Hong Xiuquan, believed he was Jesus Christ's younger brother, an uprising that was finally suppressed in 1871 by forces including Charles Gordon's Ever-Victorious Army.
