FIBONACCI SEQUENCE EXAMPLE IN NATURE SERIES

So this is a way to approximate the theoretical best packing: form 3 seeds every 5 turns, or 5 seeds every 8 turns, or 8 every 13 turns, and so on. You will find that the quotient comes closer and closer to Phi as you use bigger F-numbers. Make fractions that have a Fibonacci number in the numerator and the previous Fibonacci number in the denominator: 5/3, 8/5, 13/8, 21/13, and so on. The Fibonacci Numbers Approximate the Golden Mean Notice that in the last example the “seeds” could be pushed closer and fill the space more efficiently. Notice a decrease in overlap and increased use of space in the last example.Ī diagram showing the progression of 1 to 5 “seeds” per rotation to phi. In the illustration (click to enlarge) the examples progress from 1/2 to 1/6 turn per cell, and then Phi. This will give the least amount of overlap and the best packing. So the ideal pattern would be to produce a new seed every 137.5 degrees of rotation. If you divide a circle by phi, you get 2 angles, the smaller of which is about 137.5 degrees. One such irrational number is Phi, the golden ratio, 1.61803…. The theoretical best fraction would be an irrational number which cannot be expressed exactly by whole numbers. Any rational fraction (the top and bottom are whole numbers) will give this effect. Most of the space between each line of cells is wasted. If cells grow every ½ turn then they pile up in 2 lines, 1/3 turn would give 3 lines, and so on. How much of a circle should the growth center rotate before growing a new cell? If it rotates a whole turn then the cells still pile up on each other in 1 line. As they form, the center of growth is rotating so that the cells don’t end up on top of each other. Plants grow from active tissue called the meristem, most often at the tip of the branches. This optimal packing means that the plant can build a smaller structure to hold them.

The pine scales and seeds are arranged in a way that requires minimum space. The pattern represents an optimization of resources. This gives 1, 1, 2, 3, 5, and so on as above.

FIBONACCI SEQUENCE EXAMPLE IN NATURE SERIES

This series is formed from the starting numbers 1, 1, and then adding together the last 2 numbers to get the next one. The sequence 5, 8, 13, 21, 34, and 55 are members of the Fibonacci series.

The numbers occur in these pairs more often than not. How many in each direction? There can be 5 and 8, 8 and 13, 21 and 34, 34 and 55, and sometimes more. Fibonacci Numbers appear when you count the spirals The spirals can be seen in both clockwise and counterclockwise directions. The scales of the cones and the seeds in the flower trace graceful spirals radiating out from the center. Pine cones and flower heads of the composite family of flowers both show a similar pattern. Thus, we can say that there are infinite numbers in the Fibonacci Sequences.Fibonacci numbers can be found in many remarkable patterns in nature. Simillary adding the previous two terms we can easily find the next term in the Fibonacci Sequence Series. The number in the Fibonacci Sequebce Series are called the Fibonacci Sequence Numbers.Īll the numbers in Fibonacci Sequence are Integers and the starting ten numbers in the Fibonacci Sequence are,Īs we observed that the nth number in the fibonacci sequence is the sum of previous two terms, i.e. Thus, we see that f or the larger term of the Fibonacci sequence, the ratio of two consecutive terms forms the Golden Ratio. Let us now calculate the ratio of every two successive terms of the Fibonacci sequence and see the result. The Fibonacci Spiral is shown in the image added below,Īfter studying the Fibonacci spiral we can say that every two consecutive terms of the Fibonacci sequence represent the length and breadth of a rectangle.

The side of the next square is the sum of the two previous squares, and so on.Įach quarter-circle fits perfectly within the next square in the sequence, creating a spiral pattern that expands outward infinitely. We start the construction of the spiral with a small square, followed by a larger square that is adjacent to the first square. This pattern is created by drawing a series of connected quarter-circles inside a set of squares that have their side according to the Fibonacci sequence.
