## Fibonacci sequence Gold/Gray - 5"x16"

The Fibonacchi Sequence is a numerical pattern found in mathematics and nature - from flower petals and pinecones to seashells creating versatile designs.

It is characterized by the fact that every number after the first two is the sum of the two preceding ones, i.e., 0, 1, 1, 2, 3, 5, 8 13,21, 34 ... The next number is found by adding up the two numbers before it.

According to the Temple University Math Department, the story began in Pisa, Italy in the year 1202. Leonardo Pisano Bigollo was a young man in his twenties, a member of an important trading family of Pisa. In his travels throughout the Middle east, he was captivated by the mathematical ideas that had come from India through the Arabic countries. When he returned to Pisa he published these ideas in a book on mathematics called Liber Abaci, which became a landmark in Europe. Leonardo, who has since come to be known as Fibonacci, became the most celebrated mathematician of the Middle Ages.

Consider an elementary example of geometric growth - asexual reproduction, like that of the amoeba. Each organism splits into two after an interval of maturation time characteristic of the species. This interval varies randomly but within a certain range according to external conditions, like temperature, availability of nutrients and so on. We can imagine a simplified model where, under perfect conditions, all amoebae split after the same time period of growth. So, one amoeba becomes two, two become 4, then 8, 16, 32, and so on.
