[Q]: One reactant for this reaction is best prepared by an S N 2 nucleophilic addition of a triphenyl compound, followed by elimination of the hydrogen halide by an organolithium reagent. This reaction itself proceeds through a rather unique intermediate formed when the pi electron from the reagents carbon-oxygen double bond migrates to the positively charged pole of one reactant; this intermediate is called a an oxaphosphetane, from which a triphenyl oxide is eliminated to complete the reaction. The aforementioned positively charged pole is on phosphorous because the aforementioned prepared reactant is a phosphorous ylide. For ten points, name this reaction that produces selectively double-bonded alkenes from aldehydes and phosphorous ylides and that is named for the German 1979 Chemistry Nobel winner.
[A]: Science

[Q]: It causes the weak bluish white glow in polls of water that shield some nuclear reactors. It is created by highly energetic charged particles that displace electrons in the medium through which they travel, and the subsequent electromagnetic wave in the wake of these particles is similar to the bow wave of a fast boat. FTP, what is this light produced when charged particles move through a medium faster than the speed of light in that medium
[A]: Science

[Q]: He painted Guillaime Apollinaire as a red-jumpsuited strongman and himself as a harlequin in his Family of Saltinbanques. Featureless black figures comprise his Don Quixote, while another of his works depicts a mother crying over her dead child on the left while a disfigured horse dominates the center. Parisian prostitutes in (*) African masks appear in this artist's Demoiselles (deh-mwah-ZELZ) d'Avignon. For 10 points, name this painter whose Blue Period works preceded his co-founding of Cubism and creation of 1937's Guernica.
