## Fibbonacci

Fibonacci was an Italian mathematician born around 1170 in the town of Pisa  Italy. Fibonacci’s father was a popular merchant who owned a trading post in North Africa. He was often traveling with his father which gave him many opportunities to learn about different cultures and societies. He began his studying with an Arabic master and as he traveled around he learned about different numerical systems. He went to North Africa for his studies and there he learned his first numeric system which was the Arabic number system. At the age of 30 Fibonacci returned back to Italy and began his writing.

Fibonacci wrote many books such as the Liber Abaci, which explained the Arabic numerical system. The De Practica Geometrie that showed the important parts of the Greco-Arabic geometry system. The Book Of Squares also known as Liber Quadratorum a book on algebra published in dedication of Holy Roman Emperor Frederick II. Fibonacci lived in a time where there was no printing press so the only way to get a copy of a book was to have the copy hand-written. This reason made some other books of Fibonacci less popularized than the others. Fibonacci’s books brought new systems of math and new concepts to Italy and over time his books would make a huge impact.

Fibonacci introduced a new system of numbers now named The Fibonacci Sequence which first came around his his book Liber Abaci. This sequence is converged on phi and is really simple to use. The Fibonacci Sequence can be visualized as a  spiral and then can be put into nature. The spirals of hurricanes, galaxies, and the breeding of rabbits can all be examples of the fibonacci sequence.

This sequence is based off the idea that in order to get a new number you add up the two previous numbers (0,1,1,2,3,5,8,13,21,34,etc.). This sequence is used today mostly with situations that involve money such as the stock market.

Fibonacci had a relationship with the emperor of the Holy Roman Empire, Frederick II, who he dedicated Liber Abaci too. The emperor learned about Fibonacci through his scholars, as he had an interest in mathematics and science, and they quickly started to collaborate together. They all worked on many mathematical problems and eventually posed solutions to problems in the book Flos by Johannes of Palermo. At about the year 1240 Fibonacci was recognized by Rome, for his inspirations to Italy and other locations around the globe, with a fixed salary.

Ever since then there has been many different concepts named after fibonacci such as Fibonacci coding and Fibonacci polynomials. In the town of Pisa Italy there was a statue built to recognize him in the year of 1863. There are many different books that talk about Fibonacci and the Fibonacci sequence.
