WebIn the mathematics of circle packing, a Doyle spiral is a pattern of non-crossing circles in the plane in which each circle is surrounded by a ring of six tangent circles. These patterns contain spiral arms formed by circles linked through opposite points of tangency, with their centers on logarithmic spirals of three different shapes. Webcircle packing on it with nerve isotopic to τ, is homeomorphic to R6g−6. Furthermore, the forgetting map, f : C τ → P g, of C τ to the space P g of projective structures on Σ g which forgets the packing is injective. Namely, the packings are in fact rigid. On the other hand, any projective structure on Σ g has a canonical underlying ... 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 circles. Generalisations can be made to higher dimensions – this is called sph… datcard dicom viewer download images

So if you pack as densely as possible, then a histogram of radii would be highly biased towards the smaller diameters.
