The gold ratio is a special number that is found by dividing a line into two parts so that the longest part divided by the smallest part is also equal to the whole length divided by the longest part. It is often symbolized using phi, after the 21st letter of the Greek alphabet. In an equation form, it looks like this:
a / b = (a + b) / a = 1.6180339887498948420 ...
As with pi (the ratio of the circumference of a circle to its diameter), the digits come and go, theoretically at infinity. Phi is generally rounded to 1,618. This number has been discovered and rediscovered many times, which is why it has so many names - the Golden Mean, the Golden Section, the divine proportion, etc. Historically, the number can be seen in the architecture of many ancient creations, such as the Great Pyramids and the Parthenon. In the Great Pyramid of Giza, the length of each side of the base is 756 feet with a height of 481 feet. The ratio of the base to the height is approximately 1.5717, which is close to the proportion of gold.
