Fibonacci sequence in nature tree series#

If we extend the series out indefinitely, the ratio approaches ~1.618:1, a constant we call phi, that is represented by the greek letter φ 3 petals One common natural example is the number of petals on flowers, though of course there are exceptions. Here's an interesting example called the Fibonacci series, named after an Italian mathematician of the Midde Ages, though the Greeks clearly knew all about it much earlier, as evidenced in the design of classical architecture such as the Parthenon. A Stature of Fibonacci was erected in Pisa, Italy in his honor and the date November, 23 (11-23) was set aside to honor this great mathematician.Math is at the heart of many of the patterns we see in nature. For all his work Fibonacci is considered to be one of the most influential Mathematicians of the Middle Ages and throughout history. Fibonacci published other important volumes including a journal that employed algebraic methods to solve complex geometrical problems and the use of squares and square roots as part of the numbering system. This book is cited as one of the leading forces behind Europe’s adoption of the present numbering system and the development of Fibonacci sequence in popular culture. Fibonacci published the book Liber Abaci (Book of Calculations) in 1202 that both detailed the repeating sequence of numbers and explained why the Hindu – Arabic numerical system was easier and more accurate than the Roman Numerical system that was still widely used throughout Europe. As part of his travels he was exposed to the Hindu Arabic numerical system (our present system of numbering 1, 2, 3 etc.) for conducting business and may have learned about repeating sequence of numbers from the ancient journals of Indian Mathematicians. Leonardo Fibonacci (1170 -1250) traveled extensively throughout the Mediterranean Region and Middle East during his formative years. Scientists believe that this radial pattern is the most effective way to organize plant parts to optimize space along a stem and maximize exposure to sunlight, etc., so that plants exhibiting these characteristics would have a competitive advantage over those that do not.

In nature Fibonacci numbers normally create a spiral shape when they are plotted and you can often see this shape in the way flower petals, tree limbs, sea shells etc. This can be illustrated arithmetically by Xn = Xn-1 + X n-2. The Fibonacci sequence normally begins at 0 or 1 and the next number corresponds to the sum of the previous two numbers. This Fibonacci sequence is often called nature’s numbering system because it is so commonplace. This sequence of numbers was named the Fibonacci sequence in honor of Leonardo Fibonacci an Italian Mathematician who referenced this order of numbers in a book he wrote in 1202. In the natural world there are certain patterns of numbers that repeat themselves over and over again, in the way flower petals are attached to a stalk, branches grow from a tree, bracts are arranged on a pine cone, leaves are arranged on a stem, etc. Consider yourself lucky if you find a four leaf clover because they are rare in nature.
