One of these figures named after Riemann represents the complex plane using the stereographic projection.
One of these figures named after Riemann represents the complex plane using the stereographic projection. The eversion of one of these objects is possible by Smale's paradox. One of these figures is homeomorphic to a simply connected closed 3-manifold, according to the Poincare [pwan-ka-REY] conjecture. One of these objects can be transformed into two, each the size of the original, by the Banach-Tarski paradox. The volume of one of these figures is four-thirds pi R cubed. For 10 points, name this three-dimensional object exemplified by a globe or ball
