Fibonacci
From Wikipedia, the free encyclopedia
Fibonacci (around 1175 - 1250) was a famous Italian mathematician. His real name was Leonardo of Pisa or Leonardo Pisano. His nickname Fibonacci was taken from his father, whose name was Bonacci. Fibonacci means son of (a) Bonacci. His mother was Alessandra Larracocci. He was 9 when she died. He had a sister named Saminta. He is considered the "Father of Mathematics".
[change] Fibonacci number sequence
Fibbonacci is best known for the list of numbers called the Fibonacci Sequence. The list never stops, but it starts this way:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
In this list, a person can find the next number by adding the last two numbers together.
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13
8 + 13 = 21
13 + 21 = 34
21 + 34 = 55
34 + 55 = 89
55 + 89 = 144
89 + 144 = 233
144 + 233 = 377
233 + 377 = 610
377 + 610 = 987
610 + 987 = 1597
987 + 1597 = 2584
etc...
This series is also interesting because the ratio of two adjacent numbers in the series approaches the golden ratio, or Phi, as the numbers get bigger.
