Question
These objects name natural transformations from a constant diagram to a diagram of the same shape, “universal” examples of which are category theoretic limits. Vector space subsets that are closed under positive scalar multiplication are named for these objects. In the standard parameterization of these objects, replacing the equation “z equals r” with “z equals theta” instead yields a helicoid. “Excesses” and “defects” are derived from these objects in the best-known work by (*) Apollonius of Perga. Slicing a “double” one of these objects with a plane yields hyperbolas and parabolas as namesake “sections.” For 10 points, name these surfaces that contain a volume of one-third pi r-squared h. ■END■
ANSWER: cones [accept cone of a functor or cones of a functor or universal cones or Conics or conic sections or double cones; prompt on nappe by asking, “What is the name of a single nappe?”] (The words “hyperbola” and “ellipse” come from the Ancient Greek words for “excess” and “defect,” respectively.)
