question:
In 1695, Josua de Grave made another study of the same subject as this painting, but from a different angle. In the center fight of this painting, the roof of the Armamentarium is just visible behind a much larger gated building. An anecdote concerning this painting relates that it was chosen personally by William of Orange, although it was most likely purchased by the Rijksmuseum. The top half of this painting depicts only the sky, with very dark clouds at the top of this painting, and at the bottom of this painting, several people are standing by a boat while two women in black dresses are conversing to the side. The foreground and the background of this work are divided by a large river which reflects the buildings of the background. For ten points, identify this cityscape, a work by Jan Vermeer.
answer:
Fine Arts

question:
One of these organic compounds is converted to an alkene by a diorganochromium compound in the Takai olefination. Compounds may be reduced to this functionality via the use of DIBAL-H (die-bahl aitch), and alkynes are formed by a reaction of these compounds with tetrabromomethane and triphenylphosphine named for Corey and Fuchs. When these organic compounds lack a hydrogen atom in the alpha position, their disproportionation can be induced by a base in the Cannizzaro reaction. These organic compounds are oxidized to carboxylic acids by a diamminesilver (I) complex, leading to the precipitation of metal onto the inside of the vessel, giving the positive "silver mirror" result of the Tollens test. For 10 points, name this special class of ketones with one R group being just hydrogen.
answer:
Science

question:
His Productive Thinking was published posthumously in 1945. Earlier, he had earned his doctorate by inventing a lie detector for the objective study of testimony. His greatest discovery came due to the perceptions he experienced on a train trip in 1910, which led him to experiment with a stroboscope. The central tenet of his belief was Pragnanz, or "precision," in organization, a concept he formulated after his enunciation of the phi phenomenon. FTP, name this man who, with Koffka and Kohler, founded Gestalt psychology.
