At last, you find the statue! Several others are also milling about. You decide to ask nearby tourists if they know anything about the Liber Abaci.

One person smiles broadly and introduces himself as a math professor. He directs you to several other mathematicians who can help you. Click on the links below to answer the respective questions. Answer them in your historian's journal.

First, you interview the University of St. Andrews Math Department and ask them the following questions: 1) What is the Liber Abaci? 2) How did Fibonacci first begin to think about the Fibonacci Sequence? 3) What is the rule of finding the next number in the Fibonacci sequence?

Next, you interview Dr. Ron Knott at the University of Surrey who mentions the Golden Number. You ask him 1) What is the relationship between the Fibonacci sequence and the Golden Number, also known as the Golden Ratio? 2) What is the Fibonacci Rectangle, also known as the Golden Rectangle, and its relationship to a nautilus spiral? 3) How is the Fibonacci sequence related to plants and flowers?

Finally, you talk with Susan Goldstine at St. Mary's College of Maryland. She shows you some pinecones that she has colored and numbered to show the Fibonacci numbers and spirals. You take careful notes and remember her website as you will be creating your own pinecone.

The math professor encourages you to go to Paris to see the Mona Lisa and find Golden Rectangles in the painting. Click the arrow continue to the Louvre in Paris.
