10. Every third number is even and the difference between each number is .618 with the reciprocal of 1.618. These numbers are know as the “golden ratio” or “golden mean.”
11.
12. It is believed that contributions to the theory began in 200 BC by Indian mathematicians whose studies were based on Sanskirt prosody.
13. The sequence was introduced to Western European mathematics in 1202 by Leonardo of Pisa, aka “Fibonacci”
14. His study of the sequence began with the breeding patterns of rabbits. In which he found rabbit generations duplicated in accordance with the Fibonacci numbers.

17. For instance most daisies have 34, 55, or 89 petals. (The 9th, 10th, and 11 th Fibonacci numbers)
18.
19. The arrangement of seed is based upon the golden mean which corresponds to the “golden angle” of 137.5 degrees.
20. The seeds are arranged in consistent patterns of 137.5 degrees
21. This gives the flower the optimal filling ratio for its seeds.
22.
23. The numbers form what are called Fibonacci rectangles or “golden rectangles”
24. The rectangles are unique because each rectangle has sides equal to the length of the Fibonacci numbers.
25. Within these rectangles we can create a spiral with cross sections equal to exactly 1.618 (the “golden mean” with the corresponding angle of 137.5 degrees
