Nature by Numbers

In this beautiful video, "Nature by Numbers," filmmaker Cristobal Vila presents a series of animations illustrating various mathematic principles, beginning with a breathtaking animation of the Fibonacci Sequence before moving on to the Golden Ratio, the Angle Ratio, the Delaunay Triangulation and Voronoi Tessellations. The words are scary-sounding, but the math is beautiful and the film serves to remind us of the intimate relationship between nature and math.

Nature by numbers: The hidden beauty of mathematics

L iving with a mathematician this year has made me realise the unsung contribution mathematics makes when it comes to providing us with the reasoning to better appreciate the beauty of nature. I’d always thought fractal symmetry, which cropped up in my physical chemistry lectures, was solely a chemical concept. You can probably imagine my surprise when I realised that this characteristic actually stemmed from mathematics. It came as an even greater shock to discover that many natural phenomena are, in fact, fractal to some degree. The Fibonacci sequence, which you may think exists only in the pages of a Dan Brown novel, is also visible in some of nature’s most exquisite structures. So, just how many of us are aware of the way in which mathematics provides us with the reasoning to be able to praise the intrinsic beauty of nature? This is exactly what I hope to achieve in this article; to show you how mathematics, something some of us may have dreaded at school, actually explains a lot of the things we see around us.

Fractal symmetry is when the same pattern is seen at increasingly small scales. In fractal symmetry, you find the same pattern within the pattern, which is why this can also be referred to as self-similarity. The best example to think of is a tree. The trunk of a tree separates into branches which then separate into smaller branches and then twigs, and these get smaller and smaller. In this way, we see a repetition. Another example is the Romanesco broccoli, but my favourite would have to be the Lotus effect. The Lotus leaves have a rough surface with micro- and nano-structures including waxy crystals that contribute to making the surface superhydrophobic. This means that any water droplets on the lotus leaves are strongly repelled and slide off the surface. While doing so, they take up the dust particles from the leaves in order to reduce the surface tension, resulting in the cleaning of the lotus leaves. This is an example of self-cleaning in nature and it is the fractal symmetry of the waxy crystals on the surface of the leaves that provides the enhanced hydrophobicity which makes this possible.

Fractal symmetry is when the same pattern is seen at increasingly small scales. In fractal symmetry, you find the same pattern within the pattern, which is why this can also be referred to as self-similarity

Another type of symmetry I wish to discuss is the so-called wallpaper symmetry. This is the mathematical classification of a two-dimensional repetitive pattern inspired by honeycomb structures. Besides often being seen in architecture and other arts such as textiles, this structure has found great use in the field of chemical catalysis. One of the finest examples of the use of catalysis is in catalytic converters used to turn pollutant gases such as nitrogen oxides and carbon monoxides into nitrogen dioxide and carbon dioxide gases, which are safer alternatives. The support for the precious rhodium or platinum metal catalysts used is cordierite monolith. The metal is dispersed on the honeycomb structure of the support which provides a larger surface area to optimise the flow of gases over the catalyst. This is a fine example of symmetry observed in nature that has now been employed on a large industrial scale and is something used by many of us every day.

Fractal and wallpaper symmetry are the two types I wanted to discuss. However, this article would be incomplete without a nod to the spirals that are too often seen in nature. Some of these spirals arise due to the golden ratio of 1.618[…] which is the most irrational number we can get. Put simply, it is the furthest away we can be from a fraction. In this way, the golden ratio gives the best spiral with no gaps. Hence, flower petals and pinecones are guided by the golden ratio, which is related to the Fibonacci sequence. In the Fibonacci sequence, each number is the sum of the two numbers preceding it. What we find is that if we take the ratio of any two numbers from the Fibonacci sequence, we get values very close to the golden ratio. In nature, the flowers and the shells are not genetically, or in any other way, programmed to abide by the mathematics of the Fibonacci sequence. This is purely a result of evolutionary design. Petals and seeds find that the golden ratio offers the best packing with minimum gaps. I find it absolutely amazing that a series of numbers on a piece of paper can explain why many elements in nature have chosen to adopt this particular configuration.

In addition to mathematics, you could not have avoided noticing the not-so-subtle mention of chemistry in this article. As I researched more into maths, I could easily find myself making connections with chemistry and much of the material I have studied to date. Thinking back to one of the conversations I’ve had with my flatmates in the kitchen, it’s clear that mathematics provides the key to untie the knots in many fields both within and outside STEM. As a chemist, I certainly see how fundamental a role mathematics plays. In this article, I hope I have enabled you to at least begin to appreciate just how much a bunch of numbers can explain to us about the universe.

Nature by Numbers

nature by numbers reflection essay

A short movie inspired on numbers, geometry and nature

Project completed in March, 2010

Artists and architects have used since ancient times many geometrical and mathematical properties: we could take some examples simply by observing the refined use of the proportions by architects from Ancient Egypt, Greece and Rome or other Renaissance artists like Michelangelo, Da Vinci or Raphael.

But what is more surprising for me is that many of these properties and mathematical developments are also present in nature. We could find countless cases, but I wanted to refer only three of them on this short animation: The Fibonacci Series and Spiral / The Golden and Angle Ratios / The Delaunay Triangulation and Voronoi Tessellations.

nature by numbers reflection essay

The concepts behind Nature by Numbers

This section is meant to be a complement to the animation, in order to better understand the theoretical basis that you can find behind the sequences. It was also, more or less, the appearance of the screenplay in the days that I was planning this project.

The animation begins by presenting a series of numbers. This is a very famous and recognized sequence since many centuries ago in the Western World thanks to Leonardo of Pisa , a thirteenth century Italian mathematician, also called Fibonacci. So it is known as Fibonacci Sequence , even although it had been described much earlier by Indian mathematicians.

2010_nbyn_about_serie_A

This is an infinite sequence of natural numbers where the first value is 0, the next is 1 and, from there, each amount is obtained by adding the previous two.

The values of this sequence have been appearing in numerous applications, but one of the most recognized is the Fibonacci Spiral, which has always been used as an approximation to the Golden Spiral (a type of logarithmic spiral ) because it is easier to represent with help of a simple drawing compass.

nature by numbers reflection essay

This is the next thing to be shown on the animation, appearing just after the first values on the succession: the process of building one of these spirals.

2010_nbyn_about_espiral

We will create first a few squares that correspond to each value on the sequence: 1×1 – 1×1 – 2×2 – 3×3 – 5×5 – 8×8, etc. And they are arranged in the way how we see in the diagram at left.

Then we draw a quarter circle arc (90°) within each little square and we can easily see how it builds step by step the Fibonacci Spiral, looking at right graphic.

I have introduced a small optical correction in the animation in order to get the resulting curve more like a true Golden Spiral (more harmonious and balanced), as explained on this plate . It’s something similar to what happens when we try to approach to an ellipse by drawing an oval using circular segments: the result is not the same as a true ellipse. And it’s something evident.

IMPORTANT NOTE: while watching the animation conveys the idea that the Fibonacci spiral (or the Golden Spiral, it doesn’t matter) is on the origin of the shape of a Nautilus , this isn’t absolutely right.

It’s funny because if you perform this search at Google Images: “ spiral + nautilus ” you will see how many images suggest that this shell is really based on the construction system described above.

But this isn’t correct, as it’s outlined below, on the “Making of” section.

2010_nbyn_about_naut_vs_fib.png

The truth is that this is something I discovered when I had completely finished the screenplay for this project and I was too lazy to change. Therefore I must confess that I did a kind of cheat with this animation. Or you could explain in a more “genteel” way, saying that I have taken an artistic license 😅

2010_nbyn_about_nautilus.png

Once it has appeared the Nautilus we advance to the second part of the animation. It introduces the concept of Golden Ratio by constructing a Golden Rectangle. We start from a simple square to get that and use a classic method that requires only a ruler and drawing compass. See the complete process on the following series of illustrations:

2010_nbyn_about_aureo_01

This is very special rectangle known since ancient times. It fulfills this ratio, also known as the Golden Ratio or Divine Proportion: the ratio of the sum of the quantities (a+b) to the larger quantity (a) is equal to the ratio of the larger quantity (a) to the smaller one (b).

2010_nbyn_about_aureo_02

The result of this ratio (ie the division of a by b) is an irrational number known as Phi —not to be confused with Pi— and an approximate value of 1.61803399…

Formerly was not conceived as a true “unit” but as a simple relationship of proportionality between two segments. And we find in many works created by the mankind in art and architecture, from the Babylonian and Assyrian civilizations to our days, passing through ancient Greece or the Renaissance.

JUST A CURIOSITY: it isn’t evident on the animation, but there is a deep connection between the Fibonacci Sequence and Golden Ratio.

You have an example at right (we will see another one): if we divide each value in the Fibonacci Series by the previous, the result tends to Phi. The higher the value, the greater the approximation (consider that Phi, like any irrational number, has infinite decimals).

We are going one step further on the animation by introducing a new concept, maybe less known but equally important, the Golden Angle . That is, the angular proportional relationship between two circular segments:

nature by numbers reflection essay

These two circular segments are accomplishing too with the same golden proportionality, but on this case the value of the angle formed by the smallest of them is another irrational number, we can simplify and round it as 137.5 º

And this value is deeply present in nature. This is the next concept we see on the animation: how to configure the structure formed by the sunflower seeds.

Look at the figures below:

2010_nbyn_about_pipas_01.png

  • We add a first red seed.
  • Turn 137.5º
  • Add a second green color seed and make the previous traveling to the center.
  • Turn other 137.5º
  • Add a third ocher seed and make the previous traveling to the center, to stay side by side with the first one.
  • Turn other 137.5º…

…and so on, seed after seed, we will obtain gradually a kind of distributions like the ones you have in the following figures.

2010_nbyn_about_pipas_02.png

This leads to the characteristic structure in which all seeds are arranged into a sunflower, which is as compact as possible. We have always said: nature is wise :-)

ANOTHER CURIOSITY: Do you remember we had commented that there had a deep connection between the Fibonacci Sequence and Golden Ratio? Well, next we have another meeting point between both concepts. Look at the following images of a sunflower:

By observing closely the seeds configuration you will see how appears a kind of spiral patterns. In the top left picture we have highlighted three of the spirals typologies that could be found on almost any sunflower.

Well, if you look at one of the typologies, for example the one in green, and you go to the illustration above right you can check that there is a certain number of spirals like this, specifically 55 spirals. Coincidentally a number that is within the Fibonacci Sequence ;-)

And we have more examples in the two upper panels, cyan and orange, they are also arranged following values that are within the sequence: 34 and 21 spirals.

In principle, all the sunflowers in the world show a number of spirals that are within the Fibonacci Sequence. You could go out to the countryside and look for a plantation to be sure or you can also use this image of a real sunflower.

Finally we reached the third segment of the animation in which we work with a concept that is a little less known than the others: the Voronoi Tessellations , also called Dirichlet Tessellation.

I discovered this issue thanks to Hector Garcia’s personal site , which I visit almost daily (and despite being a blog dedicated to Japanese culture and everything that is related to that country, also delights us from time to time with other interesting topics, like this one about Delaunay and Voronoi ).

These geometric formations are based on a distribution pattern that is easily recognisable in many natural structures, like the wings of some insects or these small capillary ramifications in some plant’s leaves.

It is also widely used to optimise the distribution systems based on areas of influence, at the time to decide, for example, where to install phone antennas, or where to build the different delegations for a pizza chain.

Let me show you a very intuitive way to understand how it forms a Voronoi Tiling:

2010_nbyn_about_voronoi_01

Imagine we have two points: one red and another blue (top left). Start by drawing a segment joining these dots and then a second orthogonal line who is right in the middle. We have just found the bisector of the segment joining these two points.

Above right we added a third green point, generating two new bisectors that intersect with the first.

If we continue adding points to generate succesive bisectors, with their intersections, will lead to a series of polygons —Voronoi Tiles— around a set of “control points”. Thus, the perimeter of each one of these tiles is equidistant to neighboring points and defines their area of influence.

All these segments that interconnect the points form a triangular structure called Delaunay Triangulation . In the illustration below you can see the process as we continue adding points:

We can find interactive sites on the internet (like this ) to draw points, move them, and check how the structure becomes updated in real time.

In fact, if we have a series of random dots scattered in the plane, the best way of finding the correct Voronoi Tessellation for this set is using the Delaunay triangulation. And in fact, this is precisely the idea shown on the animation: first the Delaunay Triangulation and then, subsequently, the Voronoi Tessellation.

But to draw a correct Delaunay Triangulation is necessary to meet the so-called “Delaunay Condition”. This means that: a network of triangles could be considered Delaunay Triangulation if all circumcircles of all triangles of the network are “empty”.

Notice that actually, given a certain number of points in the plane there is no single way to draw triangles, there are many. But only one possible triangulation meets this condition. It is very simple: we draw a triangle using 3 points only if the circumcircle created using these 3 points is “empty” (not enclosing any other dot).

You see that in the graph below, from Wikipedia:

2010_nbyn_about_voronoi_02.png

We could rotate 90 degrees each side of the triangle using the the midpoint after defining the Delaunay Triangulation (top left), to construct the Voronoi Tiling (top right). This is exactly what the animation shows just before that the camera pulls back to show us the structure of our dragonfly wing.

We could also use the centers of each circle, marked in red, as they describe the vertices of Voronoi Tilings.

2010_nbyn_about_ala_det.png

Of course, I am pretty sure of one thing: if we take a real dragonfly, and we analyze their wings with the help of a magnifying glass or microscope ( example ), we find exceptions and deviations. But it is clear the similarity of both structures.

2010_nbyn_about_ala.png

Making of Nature by Numbers

Building a “true” golden spiral.

The genuine ancient Golden Spiral should be created drawing circular arcs connecting the opposite corners of squares in the Fibonacci multisquare tiling. In fact this should be considered an “approximate” Golden Spiral. As you can see here, the red spiral used on this animation has a subttle corrections to made it more harmonious, with a continuous curvature, since the circular arcs give us some discontinuity perception. Anyway this is too another rough approximation to a True Golden Logarithmic Spiral using the Illustrator Bezier Curves.

2010_nbyn_mo_fibonacci.png

On the next picture we can see again the difference between the golden spiral and that other one present on nautilus shell:

2010_nbyn_mo_naut_vs_fib.png

Nautilus shell: 3D model process

The shell modeling was a great challenge. On the next gallery you will find a small step by step, with descriptions on each image:

nature by numbers reflection essay

And here is a close-up render showing the final result of that modelling process:

2010_nbyn_mo_nautilus3d_final

Building the wing structure

The wing skeleton was planned and designed using Illustrator, looking at some Flickr photograph references. All the geometrical structures were easily solved there and then exported to Cinema4D where I converted all to tubes, exported to Modo to integrate with the overall dragonfly body geometry and finally come back to Cinema4D again to proceed with texture and animation work. Yes: kind of convoluted pipeline, but it worked great for me :-)

2010_nbyn_mo_wing_structure.png

Sunflower 3D model

A small curiosity: those small florets around the central seeds are, actually, the REAL flowers. The sunflower itself is a “head”, a so called “composite flower”.

2010_nbyn_mo_sunflower_model.jpg

Dragonfly 3D model

As many other models on this project, the dragonfly was modelled in Modo and then exported to Cinema 4D to be textured, rigged and animated. Here are some screen-captures from Modo:

nature by numbers reflection essay

Procedural animation

This project, Nature by Numbers, was a milestone in my day to day with Cinema4D. Working on it I learned a lot of techniques within the field of what we could call  “procedural animation” (or even better: “not key-framed animation”) thanks to the use of Xpresso, a kind of visual programming system by graphical nodes. Read notes for each image once is enlarged:

Nature by Numbers

The quest for understanding the self and search for the meaning of life is as old as memory. No one can give us the correct answer because for each one of us, the path to the answer is different. But clues are all around in nature because understanding Self is linked to understanding life . In this post, we look for answers in nature by numbers and see where they lead us. Many people are afraid of Math because no one helped them make friends with numbers. Nobody introduced them to the wonder and wisdom that is hidden in the language of the Universe.

nature by numbers reflection essay

After all the positive feedback for our Healing forest learning program and requests for more nature games, meditations and mindfulness activities we have come up with this interesting walk format. We hope these mindfulness exercises help you create new learning and a new respect for yourself. Because nature and numbers are a part of you, just as you are a part of them. But first, here’s an inspiring film by Cristobal Vila.

NATURE BY NUMBERS FILM

NUMBERS IN NATURE & MEDITATION

Let us take a slow and gentle walk in nature. Our aim is to observe and reflect. Walk with a few like minded friends or go alone. Carry a pen and paper to note down your insights and experiences. And be open to try something new. ( A free download of all nature meditations in this article is given at the very end.)

Math is like love; a simple idea, but it can get complicated.

nature by numbers reflection essay

9 Numbers in Nature:  We begin the walk with an exercise to start seeing numbers in nature. Participants have to find the numbers 1 to 9 in their surroundings. Everyone can quickly strike off 1 and 2 as we all have one nose and two ears. The other numbers have to be found outside of the human body. For example a flower with 5 petals, an ant with 6 legs.  All participants are given a time limit of 10 minutes to find as many of the remaining numbers as possible. The exercise is to be done individually or in pairs. The group reassembles at the end of the time to work together as a team and find any missing number that no one could find.

nature by numbers reflection essay

8 Patterns in nature:   Nature is full of patterns that have astounded mathematicians and poets alike for centuries. One such pattern is called the Fibonacci. The Fibonacci sequence starts like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and so on forever. Each number is the sum of the two numbers that come before it. It’s a simple pattern, but it appears to be a kind of built-in numbering system to the cosmos. The numbers in the pattern can be found in our own DNA as well the spirals of the Galaxy. The numbers of the Fibonacci sequence are very commonly seen in petals of flowers . Examples include the lily, which has three petals, buttercups, which have five, the chicory’s 21, the daisy’s 34. These are all numbers from the Fibonacci sequence.

Nature Meditation: The aim of our exercise is to find interesting patterns in nature and take pictures. Try and see if you can collect a similar pattern in two different objects of nature.

7  Colours:  Every Colour that you see is a number. Light travels as a wave and each colour in the spectrum has a specific wavelength and frequency. Our visual sense is not only able to gauge and see different colours but also associates certain emotions with them subconsciously.

nature by numbers reflection essay

Nature Meditation: The aim of our next exercise is to spot all the 7 rainbow colours during your nature walk. Each individual makes a list of at-least 7 different colours they can observe during the walk. The aim is also to spend a little time with each separate colour and become aware of how the colour makes us feel. At the end of the exercise people who are drawn to the same colour can group together to see whether they share other common personality traits.

6 Geometry: Have you ever marvelled at the beauty and shape of a spiral sea-shell?  Geometry is all about shapes and their properties. Lines, curves and shapes that can be drawn on paper make up plane geometry, while 3 dimensional objects are part of solid geometry.  The spiral curve is one of the many examples in nature that give us a hint of the underlying simplicity which gives rise to the complexities in nature. The study of geometry allows us to become aware of the larger design of Nature. Here’s a short film on the curve called ‘life’. Watch it patiently to find a beautiful lesson for the ups and downs of life.

Nature Meditation: Creating a spiral. This can be done individually or in a group. The intention is to create a beautiful spiral with objects found in nature. Make it as big as you can. Each person starts from the same center point and creates one arm of a spiral radiating outwards. After working on it for 10 minutes, the creator stands on the outer edge of their spiral arm and starts to walk back to the center slowly and mindfully following the path of their spiral. The last person to reach the center wins. (You cannot pause and have to continue walking inward as slow as you can).*Don’t forget to erase your spiral and disperse everything back in nature, before you leave.

5 Senses are our window to the world. Every person perceives the world differently based on  how each of their different senses have developed. Staying in the city does take a toll on our overall sense perceptions where some senses can be overloaded like our sight and some underdeveloped like our smell. Being in nature allows us to relax our senses and sharpen them so that our experience of the world can become richer. Nature Meditation: Walk or sit silently in the forest. Focus on any one sense at a time for a short period of 2-3 minutes. Make a note of all the unique things you can observe and sense. Repeat the exercise with another of your senses. Notice how each sense reveals something new about the nature around us. The aim of this exercise is to bring us into the present moment and stop our thoughts from leaping into the past or future.

nature by numbers reflection essay

4 Breath of 4: In this exercise we focus on our breath to bring our mind to the present moment and take the help of numbers to build mindfulness. We use counting to stay focused on the breath. This is a very good exercise for creating alertness and concentration. The exercise is known as Box Breathing where we breathe in 4 stages. Inhale – Hold – Exhale – Hold , all with equal durations, from 2 to 5 seconds. For example, inhale for 3 seconds, hold your breath for 3 seconds, exhale for 3 seconds, hold your breath for 3 seconds. And repeat that. Do it any time you can for a few minutes This meditation makes us realise that numbers live with us as part of our lives and we can always turn to them for focus, attention and peace of mind.

3 Triangles: One of the most interesting things about triangles is that  if you sum up the three angles within any triangle, they will always total 180 degrees . The Triangle is a favorite among architects. As a geometrical object, the triangle is the strongest shape, capable of holding its shape, having a strong base, and providing immense support. 

Nature Meditation: Just like the 3 sides of a triangle, there are 3 stages that connect all life on our planet. An interesting exercise with number 3 is to observe the 3 different stages of life. Birth. Maturity. Death. Find and take pictures of objects in different stages. Reflect on how everything is changing from one stage to another.

π Circles: Take a circle. Any circle in the world. Measure it’s length, all the way around the circle. Then measure it across, from one edge to the other edge. Now divide the two lengths. You will always get the same number. 3.14… This number is called Pi and is often written using the greek symbol π. What’s strange about Pi is that the division is never complete. You can go on dividing without reaching an end. π has been calculated to over two quadrillion decimal places and still there is no pattern to the digits.   Nature Meditation: Spot the circles. Count the maximum number of circular objects one can notice in your surrounding nature within a time frame of 5 minutes. If you can, try and measure the circumference and diameter of any circle and divide them to find your own Pi. 

nature by numbers reflection essay

2 Opposites: Nature is made up of opposites. Day and night. Left and right. Sound and silence. Hot and cold. To observe the two opposing sides of nature is to understand our own true nature.  Nature Meditation: For this exercise participants divide into 2 equal groups ‘Positives’ and ’Negatives’. Members of the 2 groups walk in separate directions  and each individual (depending on their group) makes a list of 5 positives or 5 negatives they observe in nature. The groups reassemble after 5 minutes and make pairs between the positives and negatives group. Each pair then tries to see how many matching opposites do they have between their 2 lists. For e.g.: If one person wrote ‘light’ and the other person wrote ‘shadow’ then it is considered a successful match. With this exercise we observe that perception of life – positive or negative is based on our mind. And the mind can be trained to choose. * Some wise people might raise a doubt and say that in nature there are no positives and negatives. Everything just is. They are right. Agree with them and tell them it’s just a game.

1 Oneness:   Have you ever wondered why we only count in multiples of 10 ? A counting base of 10 is natural probably because we have 10 fingers. In ancient societies, a base 10 system wasn’t always used. The Sumerians used a base 60 system. This is why we count time in bases of 60 (60 minutes in an hour, 60 seconds in a minute). Machines are built using switches, so it is natural for them to count only off (0) and on (1).This system is called binary.  There can be many other number systems, but one thing connects them all. Numbers are concepts which only have meaning when they relate to each other. In a sense, it is this relationship that gives each number a specific meaning in the larger number system. For e.g 5 is related to 10,15,20,25 in a certain way. Here’s another chain of relationships: 1,2,6,24, 120….Can you figure out the next 2 numbers in this chain? Nature Meditation:  Participants take some time out to observe the many relationships that exist in nature. Each person comes up with a chain of nature relations. For e.g. Sun – Plant – Flower – Bee. The aim is to see who can come up with the longest chain of relationships… and perhaps to realize that we are all part of multiple chain of relationships, which give our life true meaning.

0The number Zero is widely seen as one of the greatest innovations in human history. Zero is both a number and a concept meaning the absence of any quantity. With the help of Zero we can do complicated equations and perform calculus. It is also at the heart of the language of computers which speak in 0’s and 1’s. In philosophical terms it represents nothingness or emptiness out of which all existence arises. We end our nature walk by taking a few minutes to walk in silence and reflect on the concept of zero.  Meditating on zero is a meditation in humility. It is to become aware that in the vastness of the Universe – both in space and time, our small individuality amounts to nothingness. And yet, just like the importance of zero, one can realize how significant even the most insignificant thing in the world can be.

Nature by Numbers

Today, I would like to share one of my favorite things: a short film by the very talented Cristóbal Vila called Nature by Numbers . The film melds the beautiful composition “Often a Bird” by minimalist composer Wim Mertens with some wonderfully imaged examples of mathematics in the natural world. I highly recommend that you watch the film in HD—it is utterly worth it.

As a work of art, I think that the film stands very well on its own. Even to a person who knows nothing about mathematics, the link between mathematics and nature is made very clear, even if the mathematics itself is obscure to the viewer. That being said, I think that there is value in going a step deeper. In the interests of fostering that deeper understanding, I would like to examine some of the mathematics on display in the film.

The Fibonacci Sequence

The film begins by introducing the Fibonacci sequence. The Fibonacci sequence is a fascinating gem of mathematics. The sequence itself, which can be described fairly simply, shows up in many branches of mathematics, including number theory, analysis, and geometry. The sequence was first described in relation to the following problem:

If a pair of [newborn] rabbits is placed in an enclosed area, how many rabbits will be born there if we assume that every month a pair of rabbits produces another pair, and that rabbits begin to bear young two months after their birth? 1 http://www.math.temple.edu/~reich/Fib/fibo.html

The rabbit population can be summarized in the following table:

In each column, we see the sequence \(1,1,2,3,5,\ldots\) This sequence, which appears in the film, is the Fibonacci sequence. In the table above, the value in each cell could be calculated using information from other cells. For instance, if we wanted to know how many newborns there would be in May, we would look at the number of mature pairs of rabbits in May, which is in turn found by adding the number of one month old and mature rabbits from April. That is, bot the rabbits that were mature in April and the rabbits that were one month old in April will bear young in May.

This can be generalized a little. In any cell after February, the value will be equal to the sum of the two cells directly above. For instance, the number of newborn rabbits in August will be equal to the sum of newborn rabbits in July and June.

Removing the context of rabbits, we can talk about the sequence in purely mathematical terms. We start with two terms: 0 and 1 (these are the zeroth and first terms, respectively). In order to get the next term in the sequence, we add the two previous terms. This means that the second term of the sequence will be \(0+1 = 1\); the third term will be \(1+1 = 2\); the fourth term will be \(1+2 = 3\); &c.

In mathematical notation, we can define the Fibonacci sequence in terms of the following equation: \(F_n = F_{n-1}+F_{n-2}\) where \(F_n\) is the \(n\)th term of the Fibonacci sequence and \(F_1=F_2=1\) (the first two terms are 1). It is conventional to define \(F_0 = 0\) 2 Chandra, Pravin and Weisstein, Eric W. “Fibonacci Number.” From MathWorld–A Wolfram Web Resource. http://mathworld.wolfram.com/FibonacciNumber.html .

The Golden Ratio

Skip ahead now to the 1:25 mark in the film, and watch until the 1:40 mark. The mathematics on display here go by quickly, but the content is definitely worth spending a little time on—the images presented represent one of the most pervasive mathematical concepts in art and nature.

We start by considering a particular rectangle. The rectangle that we are considering has a long side of length \(a\) units, and a short side of length \(b\) (shown in blue, below). If a square with sides of length \(a+b\) is appended to our rectangle, something interesting happens. The ratio \(a:b\) will be the same as the ratio \(a+b:a\).

The Golden Rectangle

This rectangle that we are considering is called the golden rectangle, and the ratio \(a:b\) is called the golden ratio. As this ratio appears to have been incorporated into many of the works of the ancient Greek sculptor Phidias, the 20th century mathematician Mark Barr suggested that this ratio be called \(\varphi\) (“phi”) in his honor 3 Weisstein, Eric W. “Golden Ratio.” From MathWorld–A Wolfram Web Resource. http://mathworld.wolfram.com/GoldenRatio.html . Using this notation, we have \({a\over b}={a+b\over a}=\varphi\).

It is possible to get a numerical value for \(\varphi\). The details are presented below, but feel free to skip them if it isn’t your cup of tea.

If we simplify the middle fraction, we get \({a+b\over a} = 1+{b\over a}\). As \(\varphi={a\over b}\), this implies that \(1+{b\over a} = 1+{1\over\varphi}\). Putting this together with the original equation, we have \(1+{1\over\varphi} = \varphi\). Multiplying both sides by \(\varphi\), we get \(\varphi+1=\varphi^2\), and moving all of the terms to the left side, we end up with \(\varphi^2-\varphi-1 = 0\).

Applying the quadratic formula, we get \(\varphi = {1\pm\sqrt{1^2-4(1)(-1)}\over 2(1)} = {1\pm\sqrt{5}\over 2}\). Of the two possible solutions, only one is positive. As we are comparing the lengths of two sides of a rectangle a negative solution doesn’t make sense, so we can ignore that solution. The remaining solution, \(\varphi={1+\sqrt{5}\over 2} \approx 1.618\), is the golden ratio.

When we defined \(\varphi\approx 1.618\) above, we did it in terms of a rectangle that has the interesting property that, when a square is appended to one side, the new rectangle has the same proportions as the original rectangle. However, this ratio appears throughout nature and the arts. For instance, the golden ratio can be seen in the construction of the Parthenon, in the proportions of Da Vinci’s Vitruvian Man , and in the arrangement of leaves along the stems of plants.

The golden ratio even seems to have some relevance to how attractive people find each other. People seem to consider faces to be more attractive when they are proportioned according to the golden ratio. This includes the general shape of the head (which might fit into a golden rectangle), the proportions of the nose (the ratio of height to width may be the golden ratio), and the ratio of the distance between the pupils of the eyes and the edges of the eyes (also a golden ratio).

It is also interesting to note that the Fibonacci sequence and the golden ratio are, in fact, very closely related. Consider the ratio of two consecutive terms in the Fibonacci sequence. The first several such ratios are listed below.

\(F_2/F_1 = 1/1 = 1\) \(F_3/F_2 = 2/1 = 2\) \(F_4/F_3 = 3/2 = 1.5\) \(F_5/F_4 = 5/3 \approx 1.667\) \(F_6/F_5 = 8/5 = 1.6\) \(F_7/F_6 = 13/8 = 1.625\) \(F_8/F_7 = 21/13 \approx 1.615\) \(F_9/F_8 = 34/21 \approx 1.619\) \(F_{10}/F_9 = 55/34 \approx1.618\)

As we get deeper into the Fibonacci sequence, the ratio between successive terms gets closer and closer to \(\varphi\). In fact, while it is beyond the scope of this post, it is possible to prove that as \(n\) goes to infinity, the ratio \(F_{n+1}/F_n = \varphi\). This is a really interesting and startling result.

The Fibonacci and Golden Spirals

If we rewind the film a bit to the section that starts at the 0:25 mark, we can see yet another connection between the golden ratio and the Fibonacci sequence.

The Fibonacci spiral.

Consider a square which measures 1 unit on a side (a in the figure above). To that square, attach a second square which measures 1 unit on a side (b). Together, these squares form a rectangle that is 2 units by 1 unit. On the long side of this rectangle, attach a square which measures 2 units on a side (c). We now have a rectangle which measures 2 units on one side, and 3 units on the other. We can continue this process (d-g) to get the above figure.

Now, let’s play with that figure a little bit. In the first square that we drew, we are now going to make an arc that starts in one corner, and ends in the opposite corner. Continuing that arc, we get a semi-circle which goes through the first two squares that we drew. From there, we continue the arc, always going from the initial corner of a square to the opposite corner. The result is shown below.

Squares made from the Fibonacci sequence.

This figure is called the Fibonacci spiral. This spiral is closely related to another spiral, called the golden spiral. The golden spiral is created by plotting the equation \(r = e^{90\cdot\theta\cdot\ln(\varphi)}\) 4 Plotting points on a polar plane works much like plotting points on the Cartesian plane. On the Cartesian plane, we have an x -coordinate and a y -coordinate. The x -coordinate tells us how far to the left or right to go, and the y -coordinate tells us how far up or down to go. In this system, both coordinates give us a distance. In a polar system, we use the coordinates r and \(\theta\). r is a distance (it stands for radius), but \(\theta\) is an angle between 0 and 360 degrees. To get a handle on polar coordinates, think about trying to get from point A to point B using a map and compass. \(\theta\) tells you which direction to go—if \(\theta\) is 0 degrees, then you go due east; if \(\theta\) is 90 degrees, go due north; &c.—and r tells you how far to go. For more information, I suggest reading the Wikipedia article on polar coordinates . . This spiral grows by a factor of \(\varphi\) every quarter rotation. That is, if the distance from the center of the spiral to the edge of the spiral is 1 unit at some angle, then 90 degrees farther along the spiral, the distance from the center to the edge will be about 1.618 units.

The golden spiral.

At this time, please take a second to look at the two spirals above. They look very similar. The Fibonacci spiral is made up of quarter circles which grow in relation to the Fibonacci sequence, while the golden spiral grows at a constantly increasing rate. It seems odd that they should look so similar. Yet it turns out the the Fibonacci spiral is a very good approximation of the golden spiral 5 If you are mathematically inclined, the reason that this happens is that the ratio between Fibonacci numbers approaches the golden ratio. Hence as the Fibonacci squares get larger, the amount of growth from one square to the next approaches the golden ratio, meaning that growth over a quarter turn gets closer and closer to the golden ratio, thereby matching the golden spiral. . To hammer home the point, have a look at this:

The Fibonacci spiral and the golden spiral on the same plane.

Note that, while the two spirals are not exactly the same, they line up very closely. If we continued the figure farther out (by adding more squares), we would see the two spirals converge more and more.

Now for one quick connection to the natural world: in the film, a Fibonacci spiral morphs into the shell of a chambered nautilus. As it grows, the nautilus builds shell chambers around itself for protection. As the animal grows at a constantly increasing rate, the chambers get larger at a constantly increasing rate. It turns out that the creature’s rate of growth closely matches the golden ratio.

Ultimately, both the Fibonacci and golden spirals are easily described, and can be visualized with minimal expertise. However, because of constraints placed upon living organisms, the clinical mathematical curves are mirrored in the graceful, organic curves of those organisms. Mathematics is often used as a tool for describing the universe, but I can think of few examples that are more beautiful and arresting than the Fibonacci spiral and the chambered nautilus.

The Golden Angle

Imagine that you are a sunflower. Like all living organisms, you have evolved to reproduce your genes. In your case, this is best accomplished by producing as many offspring as you possibly can. An obvious question arises: how can you best produce offspring?

The answer is probably to produce as many seeds as possible, as cheaply as possible. More seeds mean more offspring, and cheaper seeds mean a better chance that you will have the resources to survive long enough to allow your seeds to mature.

You could produce a long string of seeds (legumes like peas and lima beans seem to be successful doing this), but there may be some problems. First, the string of seeds that you produce can only be as long as you are tall, otherwise they might rot on the ground before maturing. Also, the cost of producing those seeds goes up, as you have to get nutrients to all of them, many of which may be at the end of long strings. In the long run, this could hurt.

So, instead, you pack your seeds as tightly as you can at the head of your flowers. The next question is then: how do you most efficiently pack your seeds?

A sunflower.

In order to address this question, we first need to figure out what constrains seed growth. There are some biological constraints which we must consider. New florets (which will become seeds when pollinated) form in the center of the sunflower head. As new florets are produced, older florets are pushed out from the center. Moreover, new florets form next to old florets, separated by a particular angle.

To model where the seeds end up as they mature, are going to get into some more notation. If you don’t like notation, just skip the box, and examine at the pictures after the box.

We can model the final locations of the seeds of a sunflower using the following equations:

\(r = c\sqrt{n}\) \(\theta = n\gamma\)

In these equations, \(r\) and \(\theta\) (the Greek letter “theta”) are the coordinates of a point in a polar plane; \(n\) is an index (this is basically the age of the seed); \(c\) is a constant scaling factor (this doesn’t actually have an effect on the overall configuration of the seeds, but is useful for fitting all of the plotted seeds into a smaller or larger area); and \(\gamma\) (the Greek letter “gamma”) is the angle between a new seed and its closest neighbor.

The value of \(r\) represents the fact that as new seeds are produced, older seeds are pushed out from the center. If the seeds were all in a straight line, then each new seed would push older seeds out by a constant unit. However, the seeds are filling a two dimensional space, so the farther out from the center a seed has been pushed, the less it has to move in order to accommodate new seeds. Because two dimensional spaces and one dimensional spaces are related by the square root, the distance that the seed has to move is related to the square root of its index. It turns out that the only thing affecting the distance of a seed from the center is the age of the seed.

The value of \(\gamma\) controls the angle between seeds. For instance, if \(\gamma = 90^{\circ}\), then each time a new seed is created, it will be offset from the previous seed by 90 degrees. This means that seed 1 will be at 0 degrees, seed 2 at 90 degrees, seed 3 at 180 degrees, and so on. Note that in this case all seeds with indices which are multiples of 4 will be at 0 degrees.

Ultimately, the configuration of seeds is dependent upon the angle between the seeds, and no other variables. Suppose that the angle between seeds is exactly 90 degrees. Then we end up with the following configuration of 605 seeds:

Configuration of seeds with gamma = 90 degrees.

There are a couple of problems here. First, note that near the end of each line, the seeds are practically on top of each other. If a real sunflower were configured in this manner, the seeds would probably kill each other. Each seed needs more space in order to grow and mature. Secondly, there is a ton of wasted space on the flower head. Wasted space means wasted resources. A more efficient configuration is definitely needed.

The next four images give other possible values of \(\gamma\). Starting in the upper left corner, and going clockwise, the values of \(\gamma\) are 45 degrees, 10 degrees, 138 degrees, and 14 degrees.

Configuration of seeds with gamma = {45, 10, 138, 14} degrees.

Looking at these configurations, it seems that \(\gamma = 138^{\circ}\) is the most efficient—it packs the seeds pretty closely together, and doesn’t waste as much space as the other configurations. But it still doesn’t look quite like a real sunflower (in fact, the \(\gamma = 14^{\circ}\) configuration looks closer to a real sunflower), and there is still quite a bit of wasted space. Can we find a more efficient configuration?

It turns out that we can, and that the ideal configuration is related to the golden ratio. The solution is demonstrated in the film starting around the 1:40 mark. Take a circle, and divide it into two arcs, such that the ratio of the length of the longer arc to the length of the shorter arc is the golden ratio. In the figure below, this implies that \(a/b = \phi \approx 1.618\). The smaller angle created by doing this is the golden angle (shown in blue), which measures about 137.5 degrees.

Construction of the golden angle.

For reasons that are well beyond the scope of this post, this golden angle is the ideal angle for arranging sunflower seeds. Mathematically speaking, we cannot find a better angle for packing seeds onto a flower head. Using this angle, we get the following configuration 6 The images of hypothetical sunflower seed configurations were made with an Excel spreadsheet, which I have made available for download . The spreadsheet was made with Excel 2004, and should work happily with any relatively recent version of the program (say, 2003 and later). Have fun! :

Configuration of seeds with gamma = the golden angle.

Qualitatively, this looks quite a bit like a real sunflower head. Here is the truly humbling fact: the mathematics discussed in this section, which have been fairly well understood for a century or two, are the result of thousands of years of rational thought and reasoning. Nature came up with an almost identical solution, but did so without the benefit of rational and intelligent guidance, working only through the mechanisms of evolution. One of the pinnacles of human reason turns out to be a problem solved through an unthinking, uncaring, irrational process. We have not discovered or invented any mathematics, but are merely describing the complexity and splendor of the world that we inhabit. Even then, our descriptions are simplified and impoverished in comparison to the real thing. How can one feel anything but humility when presented with such majesty?

Nature by numbers

Primary tabs.

The animation begins by presenting a series of numbers. This is a very famous and recognized sequence since many centuries ago in the Western World thanks to  Leonardo of Pisa , a thirteenth century Italian mathematician, also called  Fibonacci . So it is known as  Fibonacci Sequence , even although it had been described much earlier by Indian mathematicians.

This is an infinite sequence of natural numbers where the first value is  0 , the next is  1  and, from there, each amount is obtained by  adding the previous two .

The values of this sequence have been appearing in numerous applications, but one of the most recognized is the  Fibonacci Spiral , which has always been used as an approximation to the  Golden Spiral  (a type of  logarithmic spiral ) because it is easier to represent with help of a simple drawing compass. This is the next thing to be shown on the animation, appearing just after the first values on the succession: the process of building one of these spirals.

We will create first a few squares that correspond to each value on the sequence: 1x1 - 1x1 - 2x2 - 3x3 - 5x5 - 8x8, etc. And they are arranged in the way how we see in the diagram at left. Then we draw a quarter circle arc (90°) within each little square and we can easily see how it builds step by step the  Fibonacci Spiral , looking at right graphic. I have introduced a small optical correction in the animation in order to get the resulting curve more like a true  Golden Spiral (more harmonious and balanced), as explained on  this plate . It's something similar to what happens when we try to approach to an ellipse by drawing an oval using circular segments: the result is not the same as a true ellipse. And it shows.

IMPORTANT NOTE:  while watching the animation conveys the idea that the  Fibonacci spiral  (or the  Golden Spiral , it doesn't matter) is on the origin of the shape of a  Nautilus , this isn't absolutely right. It's funny because if you perform this search at Google Images: “ spiral + nautilus ” you will see how many images suggest that this shell is really based on the construction system described above. But this isn't correct, as it's outlined on  this other page .

The truth is that this is something I discovered when I had completely finished the screenplay for this project and I was too lazy to change. Therefore I must confess that I did a kind of cheat with this animation. Or you could explain in a more "genteel" way, saying that I have taken an  artistic license  ;-)

Once it has appeared the Nautilus we advance to the second part of the animation. It introduces the concept of  Golden Ratio  by constructing a  Golden Rectangle . We start from a simple square to get that and use a classic method that requires only a ruler and drawing compass. See the complete process on the following series of illustrations:

This is very special rectangle known since ancient times. It fulfills this ratio, also known as the  Golden Ratio  or  Divine Proportion : the ratio of the sum of the quantities ( a+b ) to the larger quantity ( a ) is equal to the ratio of the larger quantity ( a ) to the smaller one ( b ).

The result of this ratio (ie the division of  a  by  b ) is an  irrational number  known as  Phi  —not to be confused with  Pi — and an approximate value of  1.61803399… Formerly was not conceived as a true "unit" but as a simple relationship of proportionality between two segments. And we find in many works created by the mankind in art and architecture, from the Babylonian and Assyrian civilizations to our days, passing through ancient Greece or the Renaissance.

JUST A CURIOSITY:  it isn't evident on the animation, but there is a deep connection between the  Fibonacci Sequence  and  Golden Ratio . You have an example at right (we will see another one): if we divide each value in the Fibonacci Series  by the previous, the result tends to Phi . The higher the value, the greater the approximation (consider that Phi, like any irrational number, has infinite decimals).

We are going one step further on the animation by introducing a new concept, maybe less known but equally important, the  Golden Angle . That is, the angular proportional relationship between two circular segments:

These two circular segments are accomplishing too with the same golden proportionality, but on this case the value of the angle formed by the smallest of them is another irrational number, we can simplify and round it as  137.5 º And this value is deeply present in nature. This is the next concept we see on the animation: how to configure the structure formed by the  sunflower seeds . Look at the figures below:

  • We add a first red seed.
  • Turn 137.5º
  • Add a second green color seed and make the previous traveling to the center.
  • Turn other 137.5º
  • Add a third ocher seed and make the previous traveling to the center, to stay side by side with the first one.
  • Turn other 137.5º…

…and so on, seed after seed, we will obtain gradually a kind of distributions like the ones you have in the following figures.

This leads to the characteristic structure in which all seeds are arranged into a sunflower, which is as compact as possible. We have always said: nature is wise :-) ANOTHER CURIOSITY:  Do you remember we had commented that there had a deep connection between the  Fibonacci Sequence  and Golden Ratio ? Well, next we have another meeting point between both concepts. Look at the following images of a sunflower:

By observing closely the seeds configuration you will see how appears a kind of  spiral patterns . In the top left picture we have highlighted three of the spirals typologies that could be found on almost any sunflower.  Well, if you look at one of the typologies, for example the one in green, and you go to the illustration above right you can check that there is a certain number of spirals like this, specifically  55 spirals . Coincidentally a number that is within the  Fibonacci Sequence  ;-)

And we have more examples in the two upper panels, cyan and orange, they are also arranged following values that are within the sequence:  34  and  21 spirals . In principle, all the sunflowers in the world show a number of spirals that are within the  Fibonacci Sequence . You could go out to the countryside and look for a plantation to be sure :-)  You can also use this  image of a real sunflower  or go to  this website where this is explained, along with another curiosities. By the way, I recommend the rest of the  Ron Knott   site , a mathematician at the  University of Surrey  in England. His web is full of invaluable and educational information, all very well explained and with large doses of curious and funney elements .

Finally we reached the third segment of the animation in which we work with a concept that is a little less known than the others: the  Voronoi Tessellations , also called Dirichlet Tessellation. I discovered this issue thanks to  Hector Garcia's personal site , which I visit almost daily (and despite being a blog dedicated to Japanese culture and everything that is related to that country, also delights us from time to time with other interesting topics, like  this one about Delaunay and Voronoi ). These geometric formations are based on a distribution pattern that is easily recognizable in many natural structures, like the wings of some insects or these small capillary ramifications in some plant's leaves. It is also widely used to optimize the distribution systems based on areas of influence, at the time to decide, for example, where to install phone antennas, or where to build the different delegations for a pizza chain. Let me show you a very intuitive way to understand how it forms a Voronoi Tiling:

Imagine we have two points: one red and another blue (top left). Start by drawing a segment joining these dots and then a second orthogonal line who is right in the middle. We have just found the bisector  of the segment joining these two points. Above right we added a third green point, generating two new bisectors that intersect with the first. If we continue adding points to generate succesive bisectors, with their intersections, will lead to a series of polygons  —Voronoi Tiles— around a set of "control points". Thus,  the perimeter of each one of these tiles is equidistant to neighboring points  and defines their area of influence. All these segments that interconnect the points form a triangular structure called  Delaunay Triangulation . In the illustration below you can see the process as we continue adding points:

We can find interactive sites on the internet (like  this ) to draw points, move them, and check how the structure becomes updated in real time. In fact, if we have a series of random dots scattered in the plane, the best way of finding the correct  Voronoi Telesación  for this set is using the Delaunay triangulation. And in fact, this is precisely the idea shown on the animation: first the  Delaunay Triangulation  and then, subsequently, the  Voronoi Tessellation . But to draw a correct  Delaunay Triangulation  is necessary to meet the so-called  “Delaunay Condition”.  This means that:  a network of triangles could be considered Delaunay Triangulation if all circumcircles of all triangles of the network are “empty”. Notice that actually, given a certain number of points in the plane there is no single way to draw triangles, there are many. But only one possible triangulation meets this condition. It is very simple: we draw a triangle using 3 points only if the circumcircle created using these 3 points is "empty" (not enclosing any other dot). You see that in the graph below, extracted from Wikipedia:

We could rotate 90 degrees each side of the triangle using the the midpoint after defining the  Delaunay Triangulation  (top left), to construct the  Voronoi Tiling  (top right). This is exactly what the animation shows just before that the camera pulls back to show us the structure of our dragonfly wing. We could also use the centers of each circle, marked in red, as they describe the vertices of  Voronoi Tilings .

Of course, I am pretty sure of one thing: if we take a real dragonfly, and we analyze their wings with the help of a magnifying glass or microscope ( example ), we find exceptions and deviations. But it is clear the similarity of both structures.

Something beautiful for a sunday morning.

This is extraordinary animation from Etérea studios which is the work of a single person: Cristóbal Vila.

Note the appearence of the golden mean or golden ratio which is an irrational mathematical constant , approximately 1.6180339887.  It appears everywhere in nature and in art and appears somehow hardwired into our appreciation of beauty.

Although I was already aware of it, the beau­ty of this film­mak­er’s demon­stra­tion increased my too sim­ple notion. Thank you!

Nature's numbers

Human beings have been aware of patterns in nature for as long as they have been human. Without such an awareness, human culture cannot function. Agriculture is impossible without an understanding of the seasons; even before agriculture, hunting depended upon animal life cycles and patterns as simple as the trajectory of a thrown rock. Humans have discovered that one of the most effective tools for grasping nature's patterns is mathematics.

Some physicists think that the universe is made of mathematics. Even if this is an exaggeration, there is no doubt that the universe often behaves as if mathematics is a central component of it. It is a message that goes back well before Plato, with his celebrated image of the real world as the shadow on a wall, cast by an ideal mathematical world that we glimpse only imperfectly. It was Pythagorean philosophy which maintained that all is number. Later thinkers added geometry as well; Johannes Kepler discovered that the orbit of Mars is an ellipse, a curve that featured prominently in the geometry of Euclid. It was this geometric pattern which led Isaac Newton to formulate the law of gravity. In so doing, he introduced new mathematical tools such as calculus and dynamics, and his "System of the World" was so successful that it became a model for succeeding generations.

But models change, and today we are starting to glimpse a new vision of mathematics in nature, one that is more flexible and adaptable than the numerology of Pythagoras or the rigid geometry of Euclid. This vision is providing a mathematical understanding of nature's processes as well as its structures.

hidden within the Newtonian paradise was a philosophical time bomb; it has just exploded. For centuries science made a plausible assumption: that the key to understanding nature is to find the simple laws which underpin it. Once the laws are known, all else follows. Not so. Thanks to various scientific mavericks, we now know that simple laws can give rise to behaviour of endless complexity-and conversely, that highly complex systems often exhibit well defined, but apparently acausal, patterns.

One area that stands to benefit from this new knowledge is biology. There are many biological phenomena that we do not understand in depth. One is the evolution of organised structure in the living world; another, our main focus here, is the occurrence of mathematical form in an organism.

The maverick who led the way in this field was Sir D'Arcy Wentworth Thompson: a Scot born in Edinburgh in 1860, both zoologist and classical scholar. At a time when most zoological studies were purely descriptive, D'Arcy Thompson became convinced that many aspects of biological form hinged on universal mathematical principles. In 1917 he assembled the evidence in his book On Growth and Form.

It led its readers from basic principles to generalities-demonstrating, for instance, that the body-plans of two different species of fish can be matched one-to-one by a simple co-ordinate transformation. It related the biology of dividing cells to the mathematics of surfaces of least area and the physics of soap bubbles. It assembled insights into the geometry and numerology of plants that spanned several centuries, centred upon the strange predilection of the plant kingdom for Fibonacci numbers-the sequence 1, 2, 3, 5, 8, 13, 21, 34, 55...-in which each number is the sum of the preceding two. Most flowers have a Fibonacci number of petals.

Despite Thompson's dazzling collection of biomathematical relationships, the mathematics of living form has proved less tractable than Sir D'Arcy expected. One reason is that genetic influences play a far greater role in determining biological form than he realised. A living creature does not follow some free-flowing pattern of growth; instead, chemical instructions written in its genes organise and constrain its growth in a manner that ultimately derives from the evolutionary imperative of survival. The simplest way to sum up what we now know is to say that Thompson was almost always wrong in important details, but almost always right in spirit.

One of the problems with being ahead of your time is that you have to work with inadequate tools. But a series of recent discoveries have given us a much more organic understanding of how mathematical rules create patterns. Indeed, our very conception of what a pattern is has begun to change. Chaos theory has taught us that simple deterministic rules can create intricate and apparently random effects, which means that we must distinguish between the patterns of structure that are made explicit by the rules, and the more subtle patterns of behaviour that the rules implicitly define. Complexity theory has shown that simple large scale patterns can "emerge" from the interactions between individual units, so that the capabilities of the whole may transcend those of its parts. Global principles such as symmetry and topology have provided ways to characterise and organise not only static patterns, but the dynamics that give birth to them, and how they grow or evolve.

Some of these discoveries originated thanks to another maverick who embellished Thompson's insights-a homosexual genius who, in an age of moral intolerance, took his own life. He was Alan Mathison Turing, remembered today as a father of the electronic computer and artificial intelligence. But Turing was also a pure mathematician, making important discoveries in number theory and abstract algebra; a logician, who found a simple route to Kurt Gödel's epic discoveries about the limitations of axiomatic systems as a base for mathematics; as well as a biomathematician. He sought a mathematical theory for the patterns which appear on animals-stripes, spots, dapples, patches. Unlike Thompson, his ideas went far beyond description: he proposed a general mechanism for the formation of biological pattern, inspiring a new branch of mathematics known as reaction-diffusion equations.

According to Turing, the development of mathematical patterns in animal markings arises through the combination of two processes. One involves some chemical "trigger" for pattern formation, a morphogen, which diffuses across the embryonic creature's surface, or even through its body. The other is a local chemical reaction, taking place inside each cell, which interacts with the diffusing morphogen. Mathematicians call the resulting system a reaction-diffusion equation.

One fascinating example is a celebrated laboratory experiment known as the Belousov-Zhabotinskii reaction (mercifully shortened to BZ), after the Russian who discovered it. Until then chemists expected all reactions to happen and then stop, but Belousov's reaction cycled through the same sequence of changes over and over again; in the process forming intricate spatial patterns. A dish containing a thin layer of evenly mixed red BZ liquid, left to its own devices, will develop a blue spot which grows into an ever-expanding series of concentric red and blue rings like an archery target. If the rings are broken they curl up into spirals.

Where do the patterns come from? The answer is that the patterns arise when a uniform distribution of morphogen becomes unstable. In a stable distribution, tiny irregularities are automatically smoothed out, but this does not always happen. In suitable circumstances, a tiny random fluctuation-triggered perhaps by the thermal vibration of atoms-may grow, and the bigger it becomes the faster it grows, until eventually other influences limit its size.

Like Thompson, Turing suffered the usual fate of brilliant mavericks: although right in spirit, he was wrong in detail. His choice of equations fails to predict such things as the dependence of pattern on temperature. The large iridescent spots on the tail of a peacock seem, at first sight, to be prime candidates for Turing's theory, but the spots extend across the many filaments of a single feather as if there were no joins, whereas a diffusing morphogen would get trapped at the boundaries. Moreover, the patterns are laid down long before the mature shape develops, but it is on the adult that we see the perfect Turingesque spots. So biologists lost confidence in Turing's equations, and forgot the greater insight, which is about mathematical structure, not specific equations.

Even now, Turing's theory undergoes periodic revivals. Last year two Japanese biomathematicians found that stripes on a particular species of tropical fish obey Turing's equations accurately. Their clinching argument was that over about three months the stripes on the fish move-and the changes are precisely as Turing's equations predict. But Turing's reaction-diffusion equations are only one example of a million possibilities with similar pattern-forming features. Over the last decade variants on Turing's scheme have been devised which come much closer to capturing biological realities: among these are the "mechano-chemical" equations, which perceive growth and pattern as an interaction between chemistry and geometry. The concentrations of various chemicals, at some position in or on an organism, determine not just its surface patterns, but also its growth rate, and hence the way its shape changes. On the other hand, changes in shape can stimulate or suppress the production of those very chemicals, so that shape and chemistry form an endless feedback loop.

while mathematically-minded scientists were developing general theories of pattern formation and applying them to everything they could lay their hands on, biology was marching to a different drumbeat. Two more mavericks, Francis Crick and James Watson, had discovered what Crick modestly called "the secret of life." With a mixture of calculation and guesswork, published results and gossip, and a spate of molecular model-building, Crick and Watson stumbled upon the double helix structure of DNA. Following this breakthrough, biologists were led to the genetic code, whereby triplets of DNA "bases" define the structure of the complex proteins from which living creatures are made. The genetic code underpins nearly all of our current understanding of how living organisms replicate, develop, mutate, and evolve; and it has led to the image of life as a kind of computer algorithm, programmed in DNA and implemented in protein. At first sight, such an image leaves little room for mathematical equations such as Turing's: programmes are flexible-you can write anything you want-but equations are constrained, they can do only what the mathematics permits. So today's biology has mostly turned its back on the mathematicians, seduced by the molecular biologists.

But the latest generation of science mavericks, still in hot pursuit of the principles underlying biological form and pattern, is attempting a kind of mathematico-biological fusion which, like the jazz-rock fusion of some 1980s pop music, tries to get the best of both worlds. Successes include an explanation of those puzzling Fibonacci patterns in flowers. Stephane Douady and Yves Couder, two French mathematicians, have traced the numerology to the dynamics of cell movement: seeds, sepals, and petals begin their existence as "primordia," little clumps of cells that emanate from the tip of the plant and drift outwards from it as the plant continues to grow. Each new primordium is crowded by the previous ones, so gets pushed into the biggest available gap. The result is that successive primordia appear along a tightly wound spiral, separated at intervals by the "golden angle," which is 137.5 degrees; the Fibonacci numbers show up as fractional approximations to this golden angle. So genetics can choose between Fibonacci numbers, or even (within limits defined by the same dynamical theory) choose a few other numbers instead, but it cannot escape the mathematical constraints of plant cell dynamics.

This kind of synthesis is wonderful when it succeeds, but it is a dangerous game because anybody can stick two different things together in a superficial way. The point is to create something that transcends either component-a kind of synergy that Jack Cohen and I, in The Collapse of Chaos, call "complicity." The American biomathematician Stuart Kauffman believes he can already discern the general framework needed. His inspiration is drawn from different areas of late 20th century science: chaos theory, artificial intelligence, computer simulation, non-equilibrium thermodynamics, fuzzy logic, cellular automata. It doesn't greatly matter what these names mean, but it is important to understand that the sources of inspiration are diverse and that each, individually, is seen by the orthodox as distinctly flaky. This makes the task of today's mavericks even harder, because a strange mixture of knowledge is required to understand what they are trying to say.

The concept that sums up this flaky proto-framework is "complexity theory," which is associated with the Santa Fe Institute set up in 1984 by the Nobel prize-winning physicist Murray Gell-Mann. Complexity theory is strong on computer simulations and short on rigorous mathematics. It has an unfortunate-but, as we shall see, inevitable-flavour of mysticism. Wildly interdisciplinary, it hops from history to economics to quantum mechanics and back. It stresses the failures of much current orthodoxy, instead of basking in its own successes. It attracts scientific journalists who can always find a good story; but it repels scientific conservatives who see the public face of complexity theory and don't like it, and who are not going to waste time trying to grasp the weird concepts which allegedly lie behind it.

The underlying theme of complexity theory is that systems composed of large numbers of simple agents, interacting with each other according to simple rules, often develop curious large scale patterns. Instead of trying to solve the mathematical equations for such systems (currently impossible), or to describe them verbally (too imprecise), complexity theorists simulate them on computers and analyse the results with strange new techniques.

What they find is stunning. For example, assemblies of simple mathematical "cells" (far simpler than any biological cell) equipped with simple rules for growth, division, relocation, and chemical constitution, spontaneously assemble themselves into complex structures, patterns, shapes. You don't have to try hard to get them to do this: almost any reasonable set of rules will do. Similarly, in complexity models of evolution, the typical phenomena are those which have puzzled evolutionary theorists for decades: sudden bursts of diversity, long periods of stagnation, the spontaneous increase of order, rudimentary forms of "social" and "sexual" behaviour. In complexity models of economics the typical events are stockmarket crashes, which conventional economic theory could never explain. Complexity models have a habit of corresponding to the real world. (Adjusting more conventional models to mimic such behaviour usually requires a great deal of effort and special pleading.)

What do these simulations teach us? Literal- minded biologists look at the simple rules programmed into the complexity theorist's model of cells, and observe that a real cell is far more complex. So they argue that the model is unrealistic, hence no use. But that's only true if you think the game is to reproduce nature exactly. Complexity theorists are playing a different game: gaining insight. Simple rule-based models often produce the same kind of structures and self-organisation which real biology does. There seems to be a kind of "universality" to the spontaneous patterns of rule-based complex systems. The hope is that this can be understood, so that the simplified models can be used to explain how real cells perform some-not all, but some important ones- of their remarkable functions.

Unfortunately, it is technically difficult to pin down what this universality consists of, when it is valid, and why it occurs. The current way to get round this is to examine dozens of different sets of rules and see whether the same kinds of patterns occur-a sort of Monte Carlo statistical sampling. What most scientists, orthodox or not, would prefer is a coherent logical deduction along mathematical lines. But this may be difficult or even impossible, because the patterns observed in complex systems are usually emergent: that is, they are not obviously built into the component parts or how these interact; they seem to transcend the possibilities available to their components.

This is where complexity theory cannot avoid becoming mystical-or, at least, giving that appearance. Philosophers have struggled for a long time with emergence, and they have reached very few significant conclusions. Emergence has a mystic feel- for example, human consciousness may well be an emergent property of nerve cells, but saying so doesn't bring us any closer to understanding consciousness scientifically. Some philosophers have become very confused about emergence and causality: they feel that because mind is emergent, and (apparently) possesses free will, a conscious mind can choose to interfere with the operation of its own nerve cells and thereby subvert the laws of physics.

The solution lies in a better understanding of emergence. The word "transcend" is too strong. Emergent phenomena do not disobey rules of causality. What makes them appear to lack a cause is that the chain of cause-and-effect leading from the behaviour of the components to that of the whole is so intricate that human beings cannot grasp it. Thus, even though a mind with free will cannot discern the complex causal chain from which its freedom emerges, it cannot choose to disrupt that chain without affecting itself. Emergence is like a mathematical theorem whose statement is simple but whose proof is so long that nobody can follow it.

Complexity theory seems mystical because it is a serious attempt to develop a coherent mathematical theory of emergence. And many of the problems that worry scientists centre upon emergent phenomena. A stock market crash, for example, is the result of a very complex series of trading decisions made by thousands of individuals. It need not have a single obvious cause; it is just one of the universal emergent properties of that sort of system. This does not answer the question "why do stock markets crash?" and it certainly does not help us predict crashes. But the first step in doing this must be to place the problem in the right context-and that context is emergent behaviour in complex systems, not the over-simplifications of conventional mathematical economics.

There are drawbacks too. Although complexity theory is good at reproducing the qualitative behaviour of the real world, it is not yet developed enough on the quantitative side. To critics this shows that the new ideas are all form and no substance, but to enthusiasts it merely underlines the need for further development. Cohen and I call this the "Rolls Royce problem." Someone comes along to your car factory with (they claim) a revolutionary new idea, and you say "I'll believe you if you can improve on a Rolls Royce." But years of effort by thousands of people went into the creation of the Rolls Royce. However good the new idea is, it won't be able to compete unless it is given sufficient opportunity to develop.

Should it be given that chance? Does anything important hinge on the tendency of the natural world to produce mathematical patterns? Why do we want to know how such patterns form, anyway? It would be hard to suggest that the occurrence of, say, Fibonacci numbers in flower petals has any great economic or technological significance. Our new-found understanding of the processes that create this particular pattern is a contribution not to technology, but to what used to be called "natural philosophy." This is often characterised as knowledge for its own sake, but knowledge doesn't have a sake-we do. The natural philosophers sought knowledge because they saw it as the key to understanding, and understanding as the key to power.

More than 250 years ago a group of mathematicians became interested in the vibrations of a violin string. The long term result was the discovery of radio waves, leading to radar, television, and satellite navigation systems. The connection is that electromagnetic fields can form waves, just as the violin string does-on a mathematical level there is no significant difference. The mathematicians were not looking for wireless telegraphy when they studied the vibrations of the violin. They weren't even trying to build a better violin. They just thought that waves were interesting, and wanted to understand them. Had they not done so, physicists would not have noticed that the laws of electromagnetism imply the existence of radio waves, and engineers would not have tried to build the requisite equipment to turn them into a communications medium.

There is an even better reason for studying the patterns of living creatures than just the interconnectedness of the whole. The distinction between BZ style spirals and target patterns is crucial to our own continued existence. The pacemaker wave of electrical activity that spreads over the muscle tissue of your heart, causing it to contract as a whole and thereby function as an effective pump, is a target pattern written in electricity rather than chemicals. If that pattern is disrupted, then-just like the chemical BZ pattern-it turns into masses of swirling spirals. Your heart fibrillates, its muscle fibres no longer contracting in synchrony, and you rapidly die.

More generally, the new ideas tell us that biological form and behaviour are determined by mathematics as well as by recipes encoded in DNA. A recipe alone is not enough: it has to be cooked, and as every cook knows, a perfectly reasonable recipe can sometimes turn into a disaster when it is implemented using real ingredients. You will not avoid such a disaster by studying the recipe book; instead, you must study the dynamics of cookery.

The financial structure of today's science makes it poor at supporting fascinating but flaky new ideas. A committee which must justify its actions to political or industrial masters (who may view any failure as wastage) will prefer to fund yet another piece of mainstream work rather than to gamble on novelty. This is why we need science mavericks like those who are uncovering nature's numbers.
