[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.
[A]: Science


[Q]: In one story, a goddess was persuaded by a fox to sleep with this figure, and she subsequently fathered eight gods who could cure eight different body parts. This deity was sometimes known as the "Lord of semen," and in one story his semen caused seven different types of plants to sprout from the earth. This figure asked a sun god to make footprints in the ground so that he could fill them with water, giving life to a barren island called Dilmun. This figure saved humanity by warning Atrahasis of a coming flood and, in another story, the misfortunes of humans were a result of a contest between this figure and Ninhursag. This figure causes a confusion of tongues in a speech to Enmerkar, and he was sometimes represented as half-goat and half-fish. Commonly called the "Lord of Abzu," this figure ruled from the city of Eridu and in one story was seduced by the goddess Inanna. For 10 points, identify this Sumerian deity of knowledge, fertility, and water, who was later identified with the Babylonian Ea.
[A]: Social Science


[Q]: A derivative of phthalic anhydride, this compound was freqently used in laxatives until it was discovered that it might be carcinogenic. It is insoluble in water but soluble in most basic solutions or acetone, and for its primary use is most frequently found in a 1% alcohol solution. For 10 points, identify this crystalline organic compound with formula C20 H14 O4, an indicator which turns red above a pH of 9.6.
