A slightly harder question

In surevers (fwiw) almost nobody expresses a preference for rectagles laid out in that ratio aestetcially. Most architect don't use it - but believes other do. It happens to be useful in laying ouy leaves in nature. It is often used as an ratio in body parts.
However I could probably define the ratio of distance between the average arse and elbow as the golden ratio and find enough cases where the number appeared relevant.Last edited by ASB; 12 May 2009, 13:44.Comment

Originally posted by conned tractor View PostNot much interest in trying to solve it but here is the answer.
If you take the fibinacci series, 1, 1, 2, 3, 5, 8, 13, 21.... a natural solution to many problems, something like multiplying rabbits or something like that, can't remember an example.
Then take the ratio of consecutive numbers in this series, i.e., 1/1, 2/1, 3/2, 5/3, 8/5, 13/8....this gives the sequence shown. it converges to what is known as the golden number which is 1.618....
Now the golden number is used many times throughout history and in nature, the ancient greeks used to build important buidings to the ratio as it was considered to be the most aesthetically pleasing ratio for a rectangle. Whereby the width was, for example, 1.618 * height. Thus the height was 1/1.618 * width, 1/1.618 being 0.618.
It is also a root of the quadratic x^2 - x - 1. The other root being the exact inverse of this, i.e. 1.618 = 1/0.618 which as shown is also the reciprical.
Also, some sea shells and certain proportions of humans exhibit the proportionality from what I can remember. Anyway, there are much more details here:
