Question: 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.

Answer: Science

Question: One incident during this conflict saw Redvers H. Buller ordering troops into regions such as Colenso and the Stormberge mountains, only to see them soundly whipped in a period referred to as "Black Week. " After Bullers' replacement by Frederick S. Roberts, one side began a string of military victories which culminated in the defeat of Piet Cronje. A precipitating event of this conflict included the actions of Leander Jameson, while another issue of tension revolved around the discovery of gold in the Witwatersrand region. The wrap up to this war saw Horatio Kitchener setting up concentration camps while fending off guerrilla attacks led by men like Jan Botha and Jan Christiaan Smuts. For 10 points, identify this conflict that lasted from 1899 to 1902 that pitted the British against the Dutch-descended Afrikaners in what is now South Africa.

Answer: History

Question: In an important experiment, its beta subunits were bonded to nickel on a glass surface, and an actin filament attached to its gamma subunit was observed. Its mechanism was elucidated in an experiment when sunlight was shone towards artifical vesicles containing bacteriorhodopsin, and it is inhibited by DCCD and oligomycin. The gamma subunit of the F0 rotates as protons pass through, and the proton motive force releases the product of this enzyme. For 10 points, identify this enzyme present in the mitochondrion, which uses chemiosmosis to catalyze the production of a high energy molecule by phophorylating ADP.
