The Golden SectionThe Golden Section is a ratio based on a phiThe Golden Section is also known as the
Golden Mean, Golden Ratio and Divine Proportion. It is a ratio or
proportion defined by the number Phi ( It can be derived with a number of geometric constructions, each of which divides a line segment at the unique point where: the ratio of the whole line (A) to the large segment (B) is the same as the ratio of the large segment (B) to the small segment (C).
In other words, A is to B as B is to C. This occurs only where A is 1.618 ... times B and B is 1.618 ... times C. This ratio has been used by mankind for centuriesIts use may have started as early as with the Egyptians in the design of the pyramids,
It was used in the design of Notre Dame in Paris
and continues today in many examples of art, architecture and design. It also appears in the physical proportions of the human body, movements in the stock market and many other aspects of life and the universe. Dr. Stephen Marquardt has discovered a template for human beauty using the Golden Section, with obvious relevance in the plastic surgery industry. Marquardt's analysis takes ethnicity into account, and illustrates variations that are are both numerous and subtle, and clearly important in a plastic surgery guide. |
