Question: Japan's Chikyu Hakken is trying to reach this region, and n-waves travel along its upper boundary. Post-perovskite forms in the bottommost part of this region, the D double prime layer. P-waves slow down and S-waves disappear past the bottom of this region, and its top features a P-wave velocity jump from approximately seven to approximately eight kilometers per second. The low velocity zone of the asthenosphere is found in the upper part of this region. It is sandwiched between the Gutenburg discontinuity and the Moho, and this layer's namesake plumes form hotspots. For 10 points, name this layer of the earth between the crust and the core.

Answer: Science

Question: This composer's Second String Quartet depicts four men who "converse, discuss, argue...fight, shake hands, shut up then walk up the mountainside to view the firmament!" One of this composer's song texts posits a "place in the soul all made of tunes," a phrase which titles J. Peter Burkholder's authoritative study on this composer's use of musical borrowing. This composer theorized a dichotomy between musical "substance" and "manner" in the Epilogue to his Essays Before a Sonata. The dissonances of one movement by this composer were supposedly inspired by the sound of two different (*) marching bands playing simultaneously, and he wrote a piano piece that features optional flute and viola parts. That piece contains a "human faith" melody that is thematically related to quotations of the "Fate" motif from Beethoven's Fifth. For 10 points, name this composer who depicted figures like Emerson and Thoreau in his Concord Sonata.

Answer: Fine Arts

Question: The Knox-Thompson method computes the Fourier Transform of images associated with these objects. The simplest type of these is utilized in hyperfine structure analysis and utilizes a single component known as a Lummer-Gehrcke plate. In some varieties, the Martin-Puplett equation is employed in the calculation of input powers associated with them. A more common variety utilizes a gyroscope and laser, and uses the Sagnac Effect to determine angular velocity. An external modulator is typically used to vary the position of waveguides in the Mach-Zehnder type. FTP, name this common device useful for measuring phase altering media by producing its namesake figures, the most famous of which was used to disprove the existence of the ether by Michelson and Morley.
