question:
This composer reworked an instrumental sarabande into the aria Lascia ch'io planga. He called for improvised solo organ pieces to be placed ad libitum into the later of his organ concertos, a genre he invented to show off. The "Hailstone Chorus" appears in the first part of an oratorio by this man whose second part is "The Song of Moses"; that work is Israel in Egypt. One of this man's works includes a suite in G major that has a rigaudon, a minuet, and five shorter, unnamed pieces, as well as a suite in F major that begins with a (*) French overture. That piece was written to be played on barges floating on the River Thames for King George I. For 10 points, name this Baroque composer who wrote Water Music and the oratorio Messiah.
answer:
Fine Arts


question:
Loewner's inequality relates the area and systole of Riemannian metrics on one of these spaces. Arnold's cat map is a chaotic mapping from one of these spaces to itself. This name is given to connected, compact, abelian Lie subgroups, and any compact Lie group has a maximal one. Dupin cyclides are geometric inversions of these objects, and two Villarceau circles can be created by cutting one of these objects diagonally. N-dimensional versions of these objects, which have genus one, are homeomorphic to the Cartesian product of N circles. Other than the Klein bottle, these are the only closed, compact surfaces with an Euler characteristic of zero. They can be created by revolving a circle around an axis coplanar to the circle's diameter. For 10 points, name these mathematical objects that often look like doughnuts.
answer:
Science
