Named for the mathematician Leonardo of Pisa, who was known as Fibonacci, his number sequences is o, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 …Each subsequent number is the sum of the previous two. What is amazing about this sequence is that it occurs throughout nature, art, music, literature (it’s the code broken by Sophie in The DaVinci Code) and of course mathematics.
If you count the number of petals in flowers, nearly all will be a number in the Fibonacci sequence-an iris has 3, buttercup 5, delphinium 8, and ragwort 13. For more examples, watch Fibonacci Numbers-Numbers in Nature.
The ratio between successive Fibonacci numbers approximates the “golden mean,” also known as the Golden Ratio, Divine Proportion or Phi 1.618. This ratio has been used for centuries. The first use may have been by the Egyptians when they designed the pyramid.
I’m particularly interested in the Fibonacci sequence as I’m trying to make jewelry based on it. So today’s “take a break” is having fun with Fibonacci. Enjoy some of the following:
