Transcript of Who Is Leonardo "Fibonacci" Pisano?
By: Keyghan Reed Who Is Leonardo "Fibonacci" Pisano? Who Is Fibonacci? A Challenge Fit For A King Fibonacci: Genius Leonardo Pisano was born in Pisa in 1170, but was educated in North Africa where his father held a diplomatic post. Fibonacci was taught mathematics in Bugia and travelled widely with his father, recognising the enormous advantages of the mathematical systems used in the countries they visited. Returning Home The Holy Roman emperor, Frederick II, became aware of Fibonacci's work. A member of Frederick's court presented a number of problems as challenges to the great mathematician Fibonacci. In Flos, 3 of these problems were solved by Fibonacci. In one, he approximates the solution to 10x + 2x2 + x3 = 20 to 9 decimal places. Throughout his life Leonardo "Fibonacci" Pisano did many great things to help the citizens of Italy and Mathematics everywhere. Thanks to his work with number theory we have the understanding of Mathematics that we do today. Fibonacci ended his traveling around the year 1200 and at that time he returned to Pisa. There he wrote many important books that played an important role in perfecting ancient mathematical skills and he made significant contributions of his own. Out of all of his books we still have copies of Liber abbaci (1202), Practica geometriae (1220), Flos(1225), and Liber quadratorum(1225). Pay Day In 1240, the Republic of Pisa gave him a salary in recognition for the services that he had given to the city, advising on matters of accounting and teaching the citizens. The Fibonacci Sequence is the series of numbers:Full transcript
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...
The next number is found by adding up the two numbers before it.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, ... Fibonacci Number Sequence When you make squares with those widths, you get a nice spiral:
Do you see how the squares fit neatly together?
For example 5 and 8 make 13, 8 and 13 make 21, and so on.
