How to succeed in stacking

Stewart, Ian
July 1991
New Scientist;7/13/91, Vol. 131 Issue 1777, p29
Discusses the solution proposed by mathematician Wu-Yi Hsiang to Kepler's sphere-packing problem. Geometrical proof that when spherical particles pack themselves with maximum density, than a crystalline structure must result; Solid mathematical basis that links the geometrical structure of crystals to the atomic nature of matter.

    Within the framework of the discrete modeling of molecular packings, a metric approach to the investigation of the mechanisms of crystal formation is proposed. This method is based on the construction of a combination of polyhedra in a space in which the space division into polyhedra (or the...

    Using a simple model for local packing of hard spheres in random close packing state and statistical argument, we have shown that the corresponding packing density on average is 0.64. We assume that a central sphere forms a local cluster with three other spheres. Two of the neighboring ones are...

    This study proposes a classification of sphere models for grain packing types of coarse grained clastic soft and hard rocks with special emphasis on Permocarboniferous red-beds. The classification covers the range of principal packing types and different cements. Random sphere packing models are...

    Structures with regular sublattices of vacancies, vacancy clusters, and channels constructed from the fcc and bcc packings of spheres were analyzed. Homologous series of structures were constructed, and formulas were derived to correlate the basic structural characteristics with the composition...

The simulation data have been compared to results for g(3)(r,s,t) which we calculated via...
