http://websites.umich.edu/~scps/html/02chap/html/JellyBeanExample.htm In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the … See more In the two-dimensional Euclidean plane, Joseph Louis Lagrange proved in 1773 that the highest-density lattice packing of circles is the hexagonal packing arrangement, in which the centres of the circles are … See more Packing circles in simple bounded shapes is a common type of problem in recreational mathematics. The influence of the container walls is important, and hexagonal packing … See more There are also a range of problems which permit the sizes of the circles to be non-uniform. One such extension is to find the maximum possible density of a system with two specific sizes of circle (a binary system). Only nine particular radius ratios permit compact … See more At the other extreme, Böröczky demonstrated that arbitrarily low density arrangements of rigidly packed circles exist. There are eleven circle packings based on the eleven uniform tilings of the plane. In these packings, … See more A related problem is to determine the lowest-energy arrangement of identically interacting points that are constrained to lie within a given surface.
