E7 Structures are shapes derived from combining a sequence of Fibonacci ratios to form specific and precise shapes.
Fibonacci ratios are a series of ratios derived from a number series called the Fibonacci number sequence.
The Fibonacci numbers sequence is derived from the Fibonacci number series identified by mathematician Leonardo Fibonacci in the 13th century.
In mathematics, the Fibonacci numbers are the numbers in the following sequence : 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 ...
This is the Fibonacci number sequence, and it is characterised by the fact that every number after the first two is the sum of the two preceding ones.
The Fibonacci sequence is not as important as the mathematical relationships between the numbers in the series, expressed as ratios..
These ratios are the Fibonacci ratios.
