Introductory Information about the Golden Ratio
About the Golden Ratio: The Golden Ratio can be illustrated within special dimensions of Sprials, Triangles and Rectangles where the ratio of the length of the short side to the long side is .618, was noted by ancient Greek architects as the most visually pleasing rectangle and its dimensions were used to construct buildings such as the Parthenon.
The Golden Ratio has also been used extensively in classical paintings where it was believed to produce the most visually pleasing figures. The ratio also appears all over nature, such as the number of petals on some flowers, biological forms like the nautilus shell, mollusks, animal antlers, leaves, human proportions, galaxy spirals, and the relations between harmonious tones in music.
