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.

For plasmas suspended in tokamaks, this process is commonly modeled by the Hasegawa-Mima equation. It can be numerically simulated by two-equation k-epsilon or k-omega models, while simpler models include the algebraic Johnson-King and Cebeci-Smith models. A Lagrangian formulation of this process requires using a substantive derivative as a tracer and finding hyperbolic fixed points. Atmospheric instances of this phenomenon can be modeled using the von Karman constant, while like convection, analyzing it often requires averaging the stress tensor over time, a strategy known as the Boussinesq approximation. The rate of energy dissipation to the  power is inversely proportional to its length scale according to the Kolmogorov theory, and the transition to it is characterized by an increased ratio of inertial forces to viscous forces. Characterized by eddies and vortices, for 10 points, name this type of flow that occurs at high Reynolds numbers.

Headings of this work's sections include "A Lamp on Earth" and "The Sand Betrayed. " The author praises political figures such as Abraham Lincoln and Joseph Stalin in "Let the Woodcutter Awaken" and Emiliano Zapata in "The Liberators". One section of this work describes the flora and fauna of the Pre-Colombian era, and other sections discuss mining and the Communist Party, while a section often published separately describes the poet's ascent to Incan ruins. It includes "The Earth's Name is Juan" and "The Heights of Machu Picchu. " For 10 points, name this long poem by Pablo Neruda.

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.
