Fibonacci

    Design:

   In mathematics, the Fibonacci numbers are the numbers in the following integer sequence: 

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144...

The Fibonacci sequence is named after Leonardo of Pisa, who was known as Fibonacci (a contraction of filius Bonacci, "son of Bonaccio"). Fibonacci's 1202 book Liber Abaci introduced the sequence to Western European mathematics, although the sequence may have been previously described in Indian mathematics.
