Question: Harnik et al. argue against the anthropic principle by proposing a universe that lacks this. One instance of this interaction is modeled with a unitary matrix that includes three mixing angles and a complex phase that models CP violation. A vector minus axial Lagrangian for this force leads to maximal parity violation, making this force only affect left-handed particles. This force is responsible for quark flavor changing, was unified with electromagnetism by Glashow, Weinberg, and Salaam, and is transmitted by the massive W and Z bosons. For 10 points, name this fundamental force involved in radioactive decays.

Answer: Science


Question: The Keo Nua Pass in this country is one of the few passes through the Annamese Cordillera (CORE-dee-YARE-uh). This nation's capital includes the Temple of the Trung Sisters and is located on the Red River. The imperial citadel of Dai Noi is found in this country's onetime capital Hue (hway). For 10 points, name this Southeast Asian nation that was reunified in 1975 after a bloody war between the communist north and U.S.-aligned south.

Answer: Social Science


Question: In 2001, researchers at Lawrence Berkeley Labs discovered it in an aluminum matrix doped with molten lead. A mathematical description of this Wiener process typically begins with the Langevin equation and the Stokes flow for a sphere. Jean Perrin provided evidence for the most famous formulation of this process, for which, in the limit of small times, the rms displacement is proportional to the time squared. In the large time limit, it is a diffusive process which can be described by the Fokker-Planck equation and it has a diffusive constant proportional to the temperature. Observed by its namesake in pollen grains suspended in water, and explained by Einstein using the kinetic theory of gases, FTP name this random motion of small particles in a fluid.
