The numbers are also used as a combination that unlocks a safe (Rogak, 2005). While the way the Fibonacci sequence is used makes sense for the story Brown is telling, anyone who is familiar with the origins of the sequence will realize that it is traditionally not used in that way and that the way Brown used it is not what the sequence is for in a more complicated sense. Because Fibonacci numbers are so common in nature, they are also being used in man-made creations such as internet search engines (Beck & Geoghegan, 2010). Additionally, they are used in music to determine tuning and in art to show size or length of some formal elements (Beck & Geoghegan, 2010). Many people find the Fibonacci sequence fascinating because it occurs so often naturally. There must be a reason behind that, and there are all kinds of different arguments about why the Fibonacci numbers were seen biologically so frequently.
The Fibonacci sequence is interesting, and all the more so because it is seen in nature...
Once it was clearly seen in nature, people started taking that information and using it for man-made things. The main issue was that the Fibonacci sequence allowed people to figure out new ways to do things and create programs and useful items that could benefit society. Brown used the sequence to benefit his protagonist, as well, even though he scrambled it and many people did not know what it meant. By using it as an anagram, he used it in a relatively unique way. Whether his understanding of it was "right" or "wrong" can be debated, but the most important issue is that it was successful for the book in the way it was used and it did not do any harm to the current understanding of the Fibonacci sequence and its value.
