The particular atomic packing scheme in the cluster was then specified by matching the experimental diffraction pattern with that calculated from a model polyhedron, using available information ...

The springs act as touch sensors that change the patterns and colors on the LED ... and wrapped the whole thing up into a 72-sided polyhedron. There’s some impressive mechanical and electrical ...

For most people, the word “polyhedron” conjures up an image of a cube, a tetrahedron, or something similar—a solid figure with flat faces. If the polyhedron is regular, each face has the ...

Besides the regular and semiregular solids, there are just ninety-two other convex polyhedra with regular faces. In 1966, the American mathematician Norman W. Johnson, a student of H.S.M. Coxeter at ...

A polygon is regular if it is uniform and its faces are all alike. The regular convex polyhedra are the five Platonic solids, which have been known since classical Greece. The ancient Greek ...

The roundedness of the Goldberg polyhedra might make them more useful for applications where a spherical shape matters — say, for designing better patterns of dimples on a golf ball. The flat ...
