You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: The Stratton-Chu model of this phenomenon attempts to improve on earlier scalar models such as the Rayleigh-Sommerfeld theory. The equivalence of complementary arrangements in producing this phenomenon is described by Babinets principle. A simple scalar theory of this phenomenon makes use of an integral named for Kirchhoff and Fresnel, and a simple pictorial model of this phenomenon is given by Huygens principle of wave propagation. FTP name this behavior observed in electrons by Davisson and Germer, the bending of waves as they pass obstacles.

SOLUTION: Science

PROBLEM: The reciprocal relationship between the eigenvalues of the mass matrix of these particles is called the "seesaw mechanism"; the larger eigenvalue may be the mass of their "sterile" variety. One phenomenon predicted by Pontecorvo involving these entities was searched for by (*) MINOS. Reines and Cowan used an aqueous cadmium chloride solution to detect them, and other detectors tend to include large volumes of material, such as Super Kamiokande. For 10 points, name these leptons, the nearly massless products of radioactive decay whose varieties include the muon and tau and which are represented by the letter nu.

SOLUTION: Science

PROBLEM: composer used a pun on the word "celebration" to title his piece composed for a millennial in honor of Saints Cyril and Methodius, his Slavimo Slavno Slaveni! He composed the introduction and planned out a work that borrowed the "March of the Puritans" theme from Bellini's I puritani and collaborated with him, Chopin, Czerny, and others. In addition to the Hexameron, he set a Ferdinand Freiligrath poem to the third and most famous of his Liebestraum. His works for two pianos include his Concerto pathetique. He invented a genre which sought to separate concert overtures into a standalone form, examples of which include Prometheus, Orpheus, and Les preludes. This composer of a Piano Sonata in B minor also labeled his Bagatelle without tonality as his fourth Mephisto Waltz. For 10 points, name this composer who used the folk tunes of his homeland to write his nineteen Hungarian Rhapsodies.
