Leonardo Pisano :: essays research papers

da Vinci PisanoI researched a scientist or rather a mathematician that made contributions to his discipline such that they shake off affected a majority of the people that develop lived on this earth since his time. His name is Leonardo Pisano. It is hypothesized that Leonardo was born in the town of Pisa which is in modern day Italy circa 1170. Leonardo moved at a newfangled age with his sky pilot to a town in northern Algeria. Leonardos father held a diplomatic post where his job was to demo the merchants of the republic. At a young age Leonardo worked with subjects schooling the in and outs of accounting and balancing bears. In Algeria and other countries that he visited with his father he knowing different numbering placements and how they had advantages to the one that he grew up with. In Algeria from the Arabs he learned the base 10 strategy and was amenable to cracking this system across Europe which in eject was spread across the world and is now the most wide ly used number system (Connor 1998). Most people today know Leonardo by his nickname Fibonacci. By the turn of the century Fibonacci had returned to Italy and began to write texts. He wrote on number theory, geometry, algebra, and documented problems and proofs. Fibonacci lived before the printing press had been invented and all copies of his books had to be had written copies from his own hand written copies. Today we still have four of his books Liber abaci (1202), Practica geometriae (1220), Flos (1225), and Liber quadratorum. According to an article by Keith Devlin, Executive Director of the pump for the Study of Language and Information at Stanford University, Fibonaccis first book Liber abaci is the book that gave numbers to the western world. Fibonacci was born in the popish Empire and therefore was taught in his youth the Roman numeral system which is very limiting when one wants to calculate complex equations. As mentioned rather Fibonacci traveled extensively in norther n Africa with his father where he learned the base ten system from the Arabic people who in turn learned it from the people of India who developed it sometime in the first millennium. In his book Liber abaci or The Book of calculation he documented the system in detail that he learned from the Arab traders including its efficiency in playacting arithmetic (Delvin 2002).
