Dividing the 5 faces of a pentagon into a ratio of 2:3
produces the Golden Section (the ratio of the length of
the dividing chord to the length of a face is 1.61818...)

A cylinder is a 2-dimensional expansion of a circle, and a
sphere is a 3-dimensional expansion of a circle. The
ratio of proportion between a sphere and the cylinder
which encloses it is 2:3.
As The 5 Platonic Solids advance in size, they alternate
vertices to edges and faces to edges ratios of 2:3.
All larger numbers can be expressed as groupings of 2's & 3's.
