polyhedra

(these are perfectly symmetric three-dimensional fi gures, called polyhedra, where all faces, edges, and angles are the same-there are fi ve such).

So it may be that they also invented this use for polyhedra, but I was unaware of them so I am at least an independant re-inventor.

I had seen a set of models of the regular polyhedra in my High School trig class, and decided that a “12-sided teetotum” must be the 12-sdied thingy (a regular dodecahedron) I had seen in the set.

The zonohedra are based on a different approach to constructing polyhedra.

I was the first person to USE what were then being sold as “Models of the five regular polyhedra” (for mathematics teachers to show to their students), AS DICE.

This set of five polyhedra came with the faces already numbered, to make it easy to see that there were 12 sides on a dodacahedron, or 20 on an icosahedron, which made them easy to use as dice.

“The flexi-hedra started off as a whimsical use of the new flexible path feature,” says Nerd, “Once I'd seen the outcome I was hooked and developed a range of polyhedra to be given the same treatment.”

Yet the homology sphere is a sphere with the rotational group SO (3) “modulo” a discrete set of rotations which describe a polytope or polyhedra.

The physics, as described in Beating Kelvin's Partition of Space, is Denis Weaire and Robert Phelan's discovery of an improvement on Lord Kelvin's 1887 solution (14-sided polyhedra) to partitioning space with minimal interface area.
