How Did Fibonacci Find The Number Of Rabbitss

Leonardo Fibonacci, also known as Fibonacci and Leonardo of Pisa, was an Italian Mathematician who lived during the 12th and 13th century. On his journey to Africa and Syrian, he learned the Arabic mathematics, which was unknown to Europeans. Fibonacci published a book called Liber Abaci which contributed to Europe adapting the Arabic system of numbers. Liber Abaci included a thought experiment that later became known as the Fibonacci sequence. In his thought experiment, Fibonacci wanted to calculate the number rabbits that could originate from one pair of rabbits in one year. He assumed that none of the rabbits would die and each pair would produce exactly one pair of both sexes as soon as they matured at one month. After one month there are

Fibonacci observed that to find the number of rabbits one can calculate the sum of the pairs of rabbits of the previous two months. Starting with 1 pair, after on month there are 2 pairs, then 3, 5, 8, 13 and so on. The series was later observed in nature and art. The Fibonacci sequence also be explained using geometry. First, draw a square with the length 1, then another square next to it with same length, then another with length 3, then with length 5, then with length 8 and continue along the Fibonacci sequence. When you draw a quadrant in each square a spiral is formed, which is identical to the shells of snails and nautilus. This Fibonacci spiral can also be found in human ears, spiral galaxies, hurricanes, cauliflowers, pineapples, sunflower and each of those spirals in plants contains a number of seeds, florets, bumps or leaves that are equal to a Fibonacci number. Furthermore, when one number of the sequence is divided by the previous number and as the number increases, the result approaches 1.618, getting increasingly accurate, but never quite reaching that ratio. This ratio is known as The Golden Mean or The Devine
