The Golden Mean
The Golden mean is a number
The Golden Mean, or Golden Section, is a mathematical constant, a ratio that appears in nature and was discovered by Pythagoras in the 5th century BCE This proportional ratio was used in art and architecture by the Greeks and has been used by artists ever since. Leonardo Da Vinci first called it Sectio Aurea (Golden Section). This number, 1.6180339, is the Greek Phi, or Like F, Pi (3.14156), has no end.
Mathematically the golden section is demonstrated by making a point on a line positioned such that the two segments it defines have the property that the short segment has the same proportion to the long segment as the long segment has to the entire line.
The Golden Rectangle, whose sides
have a ratio of F (phi).
A rectangle whose sides are related by phi is said to be a golden rectangle, or one of the sides has length 1(x) and the other has length phi (x).
A golden rectangle has the interesting property that, if you create a new rectangle by swinging the long side around one of its ends to create a new long side, the new rectangle is also golden.
The three oldest Giza pyramids lay on a Fibonacci spiral and the opening to the Hall of Records is geometrically marked by the lines, which bisect the golden rectangle.
The opening to the Halls of Records, which hold the history of the Earth, is found in the right shoulder of the Sphinx.
This has been clearly marked geometrically. Looking at the
picture beneath, if the golden rectangle that fits around the spiral at the Giza
plateau is bisected it passes exactly through the headdress of the Sphinx. Also,
a line extended from the southern face of the middle pyramid and the line that
bisects the golden rectangle form a cross that marks a significant spot on the
right shoulder of the Sphinx.
