In 1202, a man named Leonardo of Pisa, otherwise known as Fibonacci, wrote a book entitled Liber Abaci. Fibonacci was the first Western European mathematician to introduce the sequence named for him, though it had been identified by earlier mathematician’s and grammarian’s from India. Fibonaccis’ sequence is a series of numbers in which each number is the sum of the two preceding numbers, thus: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, and so on. Fibonaccis’ work in mathematics is complex; nevertheless, the series has captured the imagination of popular culture. Because his’ sequence appears in nature—for example, the branching of trees, the scales of pinecones, the spirals of seashells, and the curve’s of waves—artists’ and writers’ have given it almost mystical significance. Its featured in The Da Vinci Code, for example, as having a role in the supposedly secret messages found in Leonardo da Vincis’ art. Although the mystical interpretations are based on fiction, Fibonacci’s remarkable accomplishment actually happened in the early 1200s.
