The Fibonacci Series
The Fibonacci series is a series of numbers developed by the Italian mathematician Leonard Fibonacci.
The series is calculated by adding two consecutive numbers to find the next in the sequence.
You will note after a bit of study that it is closely related to the Golden Mean.
It begins with 1, 1, 2, 3, 5, 8, 13 , 21, 34, 55, 89 ………. After 13 any number divided by the previous one will give a value of 1.62
the same as the golden mean constant.
A rectangle or other uniform shape such as a cylinder or rectangular box could all use the Fibonacci numbers in the design as depicted below.
