The Golden Mean

The golden ratio is represented by the Greek letter phi, an irrational number with the value of approximately 1.618. The golden mean is an aesthetically pleasing ratio derived from the Fibonacci sequence. Because of its visual appeal, creators of photographs, buildings, paintings, etc make use of the golden ratio. In the sequence, any given number is the sum of the previous two numbers. As the digits of the Fibonnaci sequence increase, the ratio between one number and its previous number becomes closer and closer to 1.618. There has been much evidence of the golden ratio in art, including works such as “Vitruvian Man” and “The Last Supper”.
