Pine cones are nature's
Magic when Fibonacci
Numbers fall from trees.

~ Deborah Stark

While browsing the Internet today, I was astonished to read the following:

Pick up a pinecone and count the spiral rows of scales. You may find eight spirals winding up to the left and 13 spirals winding up to the right, or 13 left and 21 right spirals, or other pairs of numbers. The striking fact is that these pairs of numbers are adjacent numbers in the famous Fibonacci series: 1, 1, 2, 3, 5, 8, 13, 21. . . . Here, each term is the sum of the previous two terms. The phenomenon is well known and called phyllotaxis.

Who knew pinecones were so interesting?
