Leonardo Fibonacci, also known as just Fibonacci, was an Italian mathematician from the Republic of Pisa. Born in 1175 and died in the year 1250, Fibonacci was considered to be the most talented mathematician of the middle ages. In his composition of the ‘Book of Calculations’ written in 1202, he popularized and spread the knowledge of the Hindu-Arabic numeral system in the Western world. Not only did he do his teachings of the numeral system, he introduced Europe to the sequence of numbers which he called the Fibonacci Numbers. Fibonacci numbers consists of a sequence called the Fibonacci sequence. These numbers, no matter where in the sequence you may begin, are characterized by the fact that every number after the first two displayed numbers, when added together creates the sum of the next number in the sequence. This sequence and pattern of numbers goes on infinitely.

This is where the famous Fibonacci Spiral comes into play. Also known as the Golden Spiral, this is a form of a graph that is used to calculate and convey the patterns of the Fibonacci numbers. Nature uses this number sequence for everything that we know. From the blooming and structure of something as simple as a flower, to the galaxy and stars in the sky. This number sequence is strictly all mathematical and geometric. Mathematics plays one of the biggest roles in life. Mathematics is the study of numbers and it is used for us to think logically.

The number of petals on a flower, the number of spirals on the outside of a conch shell, are just two examples of a Fibonacci numbers. When putting this sequence of numbers on a grid, you can create a rectangle, with other rectangles inside. For example, a rectangle that measures at 12.94 by 8 centimeters is in the golden ratio. This is because 12.94 divided by 8 is 1.6175. If we add the length and width of the rectangle together to get 20.94, the ratio between this and the longer side, 12.94 is 1.16182. The number 1.618034 is considered to be of perfect proportion and any number that comes close to this is also considered to be perfect. The longer the sequence of numbers goes on within this graph, the longer the Fibonacci spiral descends.
