Taken at the Phoenix Zoo in Spring 2001, this
is a beautiful closeup of the icosahedron, where the interior structure
of golden rectangles is clearly visible. Notice that the interior
structure and the icosahedron share the SAME vertices. The rectangles being
"golden" means that the longer sides are ~1.618 times that of the shorter
sides. This is a ratio very important in mathematics, seen in many places
in nature, and emulated in art.
If you are unfamiliar with
the Golden Ratio, try looking it up on the web. One good site for this
is Ron Knott's site. Go to google.com and type in "Ron Knott" and "golden
ratio", just like that, with quotes. The Golden Ratio is closely related
to the Fibonacci Numbers, where, starting with {0,1,...}, each "next" number
in the sequence is got by adding the two previous numbers in the sequence.
As the numbers in the sequence get bigger, the ratio between consequtive
numbers gets closer and closer to the Golden Ratio, so that the next
number= ~1.618 x number before it.
