It’s called the golden ratio and also the divine ratio, and its discovery lies thousands of years back when Brahmagupta described the series made by adding one number to the next, to form the next number and so on.
To explain, we start with 0 then 1, then (0+1)=1, then (1+1) 2, then (1+2)=3, then (2+3)=5, then (3+5)=8, then (8+5)=13 and so on.
This same series was introduced to the Western world by the Italian mathematician Fibonacci as the Fibonacci series – 0,1,1,2,3,5,8,13,21,34…
Then the German physicist and psychologist Gustav Theodor Fechner proposed that the ratio between the numbers of this series defines the balance in nature. Which means that the ratios 5/3, 8/5, 13/8 and so on defines the balance of nature, which comes to 1.618
This then is the signature of God in nature and a ratio that has also been used in designing everything from logos to architectural marvels – 1.618 !
Some logos that use the golden ratio are:
