question:
In one story, this god disguises himself as the farmhand Bolverk in a successful attempt to retrieve the Mead of Poetry. This god sits atop the ""high place"" of Hlidskjalf, and that which he cannot see is recalled to him by his two ever-circling ravens, Hugin and Munin. This god, who hung from the world tree on the spear Gungnir to earn mastery of the runes, will be swallowed whole by the wolf Fenrir at Ragnarok. For 10 points, name this one-eyed chief god of the Norse pantheon.
answer:
Social Science


question:
In 1999, McIlroy created an adversary for this algorithm that guarantees that it will run in worst-case time. Its worst-case runtime can be avoided by switching to heapsort after a certain recursion depth, a construction known as introsort. Like mergesort, it is easily parallelizable, and its runtime can be decreased by first selecting the median of the unsorted input list. It was invented by C.A.R. Hoare, and its second phase is the partition function, which splits the original list into lists of elements that are greater or less than the chosen pivot value. For 10 points, identify this divide-and-conquer sorting algorithm which runs in big O of n log n time, named for its speed.
answer:
Science


question:
This man defeated such rival claimants as Pescennius Niger and Clodius Albinus after coming to power, and he attempted to forestall palace coups by replacing the entire Praetorian Guard. After the death of this man, his wife Julia Domna exercised great power over his successors. He bade his time as governor of Upper Pannonia during the chaos following the murder of Commodus, eventually using the unavenged death of Pertinax as a pretext to overthrow a rich man who had won the Imperial throne at an auction, Didius Julianus. For 10 points, name this Roman emperor who ruled from 193 to 211 and was the namesake of a group that included Elagabalus, Geta, and Caracalla, the Severan Dynasty.
