instruction:
In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
question:
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.
answer:
Science


question:
The Providers order that Al-lith marry Ben Ata in one of this author's works, which is the second part of a series that ends with Krolgul and Klorathy returning to Shammat. In addition to The Marriages Between Zones Three, Four, and Five and The Sentimental Agents in the Volyen Empire, both part of this author's Canopus in Argos series, this author wrote about the birth of Ben to Harriet and David Lovatt in The Fifth Child and the cat-dog Hugo that accompanies Emily Cartwright in Memoirs of a Survivor. More well known works by this author include one in which Moses kills Mary, the wife of Dick Turner, and one in which stories from Anna Wulf's life are interspersed with excerpts from the novel Free Women. For 10 pointsname this author of The Grass is Singing and The Golden Notebook.
answer:
Fine Arts


question:
The formation of these compounds shows both a fast and slow relaxation phase, which lead to Aniansson and Wall's stepwise association-dissociation equilibrium model for their formation. Armstrong and Henry developed an HPLC variant that uses them, which analyzes proteins in biological fluids. Milk clotting results from casein forming these structures. One of their properties is determined using steady-state fluorescence quenching; that value is the number of molecules present in one of these structures at their critical concentration, known as the aggregation number. They only form above the Krafft temperature, and inverted ones form in organic solvents and have heads pointed inwards. They are the basis for the action of detergents, and are formed from surfactants. Similar to liposomes, for 10 points, name these spherical structures formed from amphipathic molecules, which have their hydrophobic tails pointing in and heads pointing out.
