The golden horn is closely related to the famous golden ratio. The ancient Greeks thought this ratio was sacred, and Leonardo da Vinci thought that the human body reflected the golden ratio.
Plants with golden angle rotation style also show another interesting mathematical attribute. The seeds on the flower head rotate both clockwise and counterclockwise, and the number of clockwise rotations is different from that of counterclockwise rotations. These two sets of numbers are called diagonal lines of plants.
These diagonal numbers have remarkable continuity. They are usually two groups of continuous Fibonacci numbers, which is another interesting thing in nature. Fibonacci numbers are arranged as follows: 1, 1, 2, 3, 5, 8, 13, 2 1 ... Each number is the sum of the first two numbers.
Fibonacci series often shows the golden section, because the ratio between two Fibonacci series numbers is very close to the golden section ratio, and the larger the two numbers, the closer it is to the golden section ratio. However, this relationship still cannot fully explain why the number of diagonal lines will eventually appear two consecutive Fibonacci numbers.
