A polyhedron with seven faces, 14 vertexes, 21 edges, and a hole makes an intriguing lamp.

Wheeler’s more ingenious plane dissections involved polyhedra, cut into smaller polyhedra, that could then be rearranged to form other polyhedra. He and his students first made these models of paper.

The top and bottom faces of this model are regular pentagons and the side faces include pentagons, triangles, and squares. The total number of faces includes thirty-five equilateral triangles, five ...

Chemists have created a molecular polyhedron, a ground-breaking assembly that has the potential to impact a range of industrial and consumer products, including magnetic and optical materials.
