The Fibonacci Sequence: Nature's Code

Männchen der Honigbiene Apis mellifera werden als Drohnen bezeichnet. Eine erschienene, mathematisch-historische Analyse zum Leben des Leonardo von Pisa, insbesondere zu seinem Aufenthalt in der nordafrikanischen Hafenstadt Bejaia im heutigen Algerien , kam zu dem Schluss, dass der Hintergrund der Fibonacci-Folge gar nicht bei einem Modell der Vermehrung von Kaninchen zu suchen ist was schon länger vermutet wurde , sondern vielmehr bei den Bienenzüchtern von Bejaia und ihrer Kenntnis des Bienenstammbaums zu finden ist. Völlig zu Recht, dass diese Fibonacci-Zahlenreihe am kommenden Samstag gefeiert wird! Abos immer bestens informiert Jetzt wählen.

The problem goes as follows: Start with a male and a female rabbit. After a month, they mature and produce a litter with another male and female rabbit.

A month later, those rabbits reproduce and out comes — you guessed it — another male and female, who also can mate after a month. Ignore the wildly improbable biology here.

After a year, how many rabbits would you have? But after a few scant paragraphs on breeding rabbits, Leonardo of Pisa never mentioned the sequence again.

In fact, it was mostly forgotten until the 19th century, when mathematicians worked out more about the sequence's mathematical properties.

But what exactly is the significance of the Fibonacci sequence? Other than being a neat teaching tool, it shows up in a few places in nature.

However, it's not some secret code that governs the architecture of the universe, Devlin said. It's true that the Fibonacci sequence is tightly connected to what's now known as the golden ratio which is not even a true ratio because it's an irrational number.

Simply put, the ratio of the numbers in the sequence, as the sequence goes to infinity , approaches the golden ratio, which is 1.

From there, mathematicians can calculate what's called the golden spiral, or a logarithmic spiral whose growth factor equals the golden ratio.

The golden ratio does seem to capture some types of plant growth, Devlin said. For instance, the spiral arrangement of leaves or petals on some plants follows the golden ratio.

Pinecones exhibit a golden spiral, as do the seeds in a sunflower, according to "Phyllotaxis: A Systemic Study in Plant Morphogenesis" Cambridge University Press, But there are just as many plants that do not follow this rule.

And perhaps the most famous example of all, the seashell known as the nautilus, does not in fact grow new cells according to the Fibonacci sequence, he said.

When people start to draw connections to the human body, art and architecture, links to the Fibonacci sequence go from tenuous to downright fictional.

Divide a number by the second number to its right, and the result is 0. Interestingly, the Golden Ratio of 0. Fibonacci retracements can be used to place entry orders, determine stop-loss levels, or set price targets.

For example, a trader may see a stock moving higher. After a move up, it retraces to the Then, it starts to go up again.

Since the bounce occurred at a Fibonacci level during an uptrend , the trader decides to buy. The trader might set a stop loss at the Fibonacci levels also arise in other ways within technical analysis.

For example, they are prevalent in Gartley patterns and Elliott Wave theory. After a significant price movement up or down, these forms of technical analysis find that reversals tend to occur close to certain Fibonacci levels.

Fibonacci retracement levels are static prices that do not change, unlike moving averages. The static nature of the price levels allows for quick and easy identification.

That helps traders and investors to anticipate and react prudently when the price levels are tested. These levels are inflection points where some type of price action is expected, either a reversal or a break.

While Fibonacci retracements apply percentages to a pullback, Fibonacci extensions apply percentages to a move in the trending direction.

While the retracement levels indicate where the price might find support or resistance, there are no assurances the price will actually stop there.

This is why other confirmation signals are often used, such as the price starting to bounce off the level.

The other argument against Fibonacci retracement levels is that there are so many of them that the price is likely to reverse near one of them quite often.

The problem is that traders struggle to know which one will be useful at any particular time. When it doesn't work out, it can always be claimed that the trader should have been looking at another Fibonacci retracement level instead.

Key Takeaways Fibonacci retracement levels connect any two points that the trader views as relevant, typically a high point and a low point.

The percentage levels provided are areas where the price could stall or reverse. The most commonly used ratios include These levels should not be relied on exclusively, so it is dangerous to assume the price will reverse after hitting a specific Fibonacci level.

Compare Accounts. His idea was more fertile than his rabbits. Just in terms of pure mathematics - number theory, geometry and so on - the scope of his idea was so great that an entire professional journal has been devoted to it - the Fibonacci Quarterly.

Now let's look at another reasonably natural situation where the same sequence "mysteriously" pops up.

Go back years to 17th century France. Blaise Pascal is a young Frenchman, scholar who is torn between his enjoyment of geometry and mathematics and his love for religion and theology.

The Chevalier asks Pascal some questions about plays at dice and cards, and about the proper division of the stakes in an unfinished game.

Pascal's response is to invent an entirely new branch of mathematics, the theory of probability. This theory has grown over the years into a vital 20th century tool for science and social science.

Pascal's work leans heavily on a collection of numbers now called Pascal's Triangle , and represented like this: This configuration has many interesting and important properties: Notice the left-right symmetry - it is its own mirror image.

Notice that in each row, the second number counts the row. There are endless variations on this theme. Next, notice what happens when we add up the numbers in each row - we get our doubling sequence.

Now for visual convenience draw the triangle left-justified. Add up the numbers on the various diagonals Fibonacci could not have known about this connection between his rabbits and probability theory - the theory didn't exist until years later.

What is really interesting about the Fibonacci sequence is that its pattern of growth in some mysterious way matches the forces controlling growth in a large variety of natural dynamical systems.

Quite analogous to the reproduction of rabbits, let us consider the family tree of a bee - so we look at ancestors rather than descendants.

In a simplified reproductive model, a male bee hatches from an unfertilized egg and so he has only one parent, whereas a female hatches from a fertilized egg, and has two parents.

Here is the family tree of a typical male bee: Notice that this looks like the bunny chart, but moving backwards in time.

The male ancestors in each generation form a Fibonacci sequence, as do the female ancestors, as does the total.

You can see from the tree that bee society is female dominated. The most famous and beautiful examples of the occurrence of the Fibonacci sequence in nature are found in a variety of trees and flowers, generally asociated with some kind of spiral structure.

For instance, leaves on the stem of a flower or a branch of a tree often grow in a helical pattern, spiraling aroung the branch as new leaves form further out.

Picture this: You have a branch in your hand. Focus your attention on a given leaf and start counting around and outwards.

Count the leaves, and also count the number of turns around the branch, until you return to a position matching the original leaf but further along the branch.

Both numbers will be Fibonacci numbers. For example, for a pear tree there will be 8 leaves and 3 turns. Many flowers offer a beautiful confirmation of the Fibonacci mystique.

A daisy has a central core consisting of tiny florets arranged in opposing spirals. There are usually 21 going to the left and 34 to the right.

A mountain aster may have 13 spirals to the left and 21 to the right. Sunflowers are the most spectacular example, typically having 55 spirals one way and 89 in the other; or, in the finest varieties, 89 and Pine cones are also constructed in a spiral fashion, small ones having commonly with 8 spirals one way and 13 the other.

The most interesting is the pineapple - built from adjacent hexagons, three kinds of spirals appear in three dimensions.

There are 8 to the right, 13 to the left, and 21 vertically - a Fibonacci triple. Why should this be?

Why has Mother Nature found an evolutionary advantage in arranging plant structures in spiral shapes exhibiting the Fibonacci sequence?

We have no certain answer. In , a mathematician named Wiesner provided a mathematical demonstration that the helical arrangement of leaves on a branch in Fibonacci proportions was an efficient way to gather a maximum amount of sunlight with a few leaves - he claimed, the best way.

But recently, a Cornell University botanist named Karl Niklas decided to test this hypothesis in his laboratory; he discovered that almost any reasonable arrangement of leaves has the same sunlight-gathering capability.

So we are still in the dark about light. But if we think in terms of natural growth patterns I think we can begin to understand the presence of spirals and the connection between spirals and the Fibonacci sequence.

Spirals arise from a property of growth called self-similarity or scaling - the tendency to grow in size but to maintain the same shape.

Not all organisms grow in this self-similar manner. We have seen that adult people, for example, are not just scaled up babies: babies have larger heads, shorter legs, and a longer torso relative to their size.

But if we look for example at the shell of the chambered nautilus we see a differnet growth pattern.

As the nautilus outgrows each chamber, it builds new chambers for itself, always the same shape - if you imagine a very long-lived nautilus, its shell would spiral around and around, growing ever larger but always looking exactly the same at every scale.

This is a special spiral, a self-similar curve which keeps its shape at all scales if you imagine it spiraling out forever.

It is called equiangular because a radial line from the center makes always the same angle to the curve. This curve was known to Archimedes of ancient Greece, the greatest geometer of ancient times, and maybe of all time.
