How Chaos Theory Unravels the Mysteries of NatureOur lives are an ongoing demonstration of this principle. Who knows what the long-term effects of teaching millions of kids about chaos and fractals will be?

Unpredictability: Because we can never know all the initial conditions of a complex system in sufficient i. Even slight errors in measuring the state of a system will be amplified dramatically, rendering any prediction useless.

Since it is impossible to measure the effects of all the butterflies etc in the World, accurate long-range weather prediction will always remain impossible.

Chaos explores the transitions between order and disorder, which often occur in surprising ways. Mixing: Turbulence ensures that two adjacent points in a complex system will eventually end up in very different positions after some time has elapsed.

Examples: Two neighboring water molecules may end up in different parts of the ocean or even in different oceans.

A group of helium balloons that launch together will eventually land in drastically different places. Mixing is thorough because turbulence occurs at all scales.

It is also nonlinear: fluids cannot be unmixed. Chaos theory looks at this unpredictability of nature and tries to make sense of it.

Chaos theory aims to find the general order of social systems and particularly social systems that are similar to each other.

The assumption here is that the unpredictability in a system can be represented as overall behavior, which gives some amount of predictability, even when the system is unstable.

Chaotic systems are not random systems. Chaotic systems have some kind of order, with an equation that determines overall behavior.

The first chaos theorists discovered that complex systems often go through a kind of cycle, even though specific situations are rarely duplicated or repeated.

For example, say there is a city of 10, people. In order to accommodate these people, a supermarket is built, two swimming pools are installed, a library is erected, and three churches go up.

In this case, these accommodations please everybody and equilibrium are achieved. The Uncertainty Principle prohibits accuracy. Therefore, the initial situation of a complex system cannot be accurately determined, and the evolution of a complex system can therefore not be accurately predicted.

Complex systems often appear too chaotic to recognize a pattern with the naked eye. But by using certain techniques, large arrays of parameters may be abbreviated into one point in a graph.

In the little rain-or-sunshine graph above, every point represents a complete condition with wind speed, rain fall, air temperature, etcetera, but by processing these numbers in a certain way they can be represented by one point.

Stacking moment upon moment reveals the little graph and offers us some insight in the development of a weather system.

The first Chaos Theorists began to discover that complex systems often seem to run through some kind of cycle, even though situations are rarely exactly duplicated and repeated.

Plotting many systems in simple graphs revealed that often there seems to be some kind of situation that the system tries to achieve, an equilibrium of some sort.

For instance: imagine a city of 10, people. In order to accommodate these people, the city will spawn one supermarket, two swimming pools, a library and three churches.

And for argument's sake we will assume that this setup pleases everybody and an equilibrium is achieved. The town expands rapidly to accommodate 20, people; one supermarket is added, two swimming pools, one library and three churches and the equilibrium is maintained.

That equilibrium is called an attractor. Now imagine that instead of adding 10, people to the original 10,, 3, people move away from the city and 7, remain.

The bosses of the supermarket chain calculate that a supermarket can only exist when it has 8, regular customers. So after a while they shut the store down and the people of the city are left without groceries.

Demand rises and some other company decides to build a supermarket, hoping that a new supermarket will attract new people. And it does. But many were already in the process of moving and a new supermarket will not change their plans.

The company keeps the store running for a year and then comes to the conclusion that there are not enough customers and shut it down again. People move away.

Demand rises. Someone else opens a supermarket. People move in but not enough. Store closes again.

Periods with high uncertainty may not be caused just by system dynamics. Environmental factors such as natural disasters, earthquakes, or floods can also cause markets to be volatile as can sudden drops in a single stock.

In finance, chaos theory argues that price is the last thing to change for a security. Using chaos theory, a change in price is determined through mathematical predictions of the following factors: a trader's personal motivations such as doubt, desire, or hope, all of which are nonlinear and complex , changes in volume, the acceleration of changes, and momentum behind the changes.

While some theorists maintain that chaos theory can help investors boost there performance, the application of chaos theory to finance remains controversial.

Show graph. Brought to you by Steam Labs. A positive MLE is usually taken as an indication that the system is chaotic. In addition to the above property, other properties related to sensitivity of initial conditions also exist.

These include, for example, measure-theoretical mixing as discussed in ergodic theory and properties of a K-system.

A chaotic system may have sequences of values for the evolving variable that exactly repeat themselves, giving periodic behavior starting from any point in that sequence.

However, such periodic sequences are repelling rather than attracting, meaning that if the evolving variable is outside the sequence, however close, it will not enter the sequence and in fact, will diverge from it.

Thus for almost all initial conditions, the variable evolves chaotically with non-periodic behavior. Topological mixing or the weaker condition of topological transitivity means that the system evolves over time so that any given region or open set of its phase space eventually overlaps with any other given region.

This mathematical concept of "mixing" corresponds to the standard intuition, and the mixing of colored dyes or fluids is an example of a chaotic system.

Topological mixing is often omitted from popular accounts of chaos, which equate chaos with only sensitivity to initial conditions. However, sensitive dependence on initial conditions alone does not give chaos.

For example, consider the simple dynamical system produced by repeatedly doubling an initial value.

This system has sensitive dependence on initial conditions everywhere, since any pair of nearby points eventually becomes widely separated.

However, this example has no topological mixing, and therefore has no chaos. Indeed, it has extremely simple behavior: all points except 0 tend to positive or negative infinity.

Topological transitivity is a weaker version of topological mixing. Intuitively, if a map is topologically transitive then given a point x and a region V , there exists a point y near x whose orbit passes through V.

This implies that is impossible to decompose the system into two open sets. An important related theorem is the Birkhoff Transitivity Theorem.

It is easy to see that the existence of a dense orbit implies in topological transitivity. The Birkhoff Transitivity Theorem states that if X is a second countable , complete metric space , then topological transitivity implies the existence of a dense set of points in X that have dense orbits.

For a chaotic system to have dense periodic orbits means that every point in the space is approached arbitrarily closely by periodic orbits.

Sharkovskii's theorem is the basis of the Li and Yorke [37] proof that any continuous one-dimensional system that exhibits a regular cycle of period three will also display regular cycles of every other length, as well as completely chaotic orbits.

The cases of most interest arise when the chaotic behavior takes place on an attractor , since then a large set of initial conditions leads to orbits that converge to this chaotic region.

An easy way to visualize a chaotic attractor is to start with a point in the basin of attraction of the attractor, and then simply plot its subsequent orbit.

Because of the topological transitivity condition, this is likely to produce a picture of the entire final attractor, and indeed both orbits shown in the figure on the right give a picture of the general shape of the Lorenz attractor.

This attractor results from a simple three-dimensional model of the Lorenz weather system. The Lorenz attractor is perhaps one of the best-known chaotic system diagrams, probably because it is not only one of the first, but it is also one of the most complex, and as such gives rise to a very interesting pattern that, with a little imagination, looks like the wings of a butterfly.

Unlike fixed-point attractors and limit cycles , the attractors that arise from chaotic systems, known as strange attractors , have great detail and complexity.

Other discrete dynamical systems have a repelling structure called a Julia set , which forms at the boundary between basins of attraction of fixed points.

Julia sets can be thought of as strange repellers. Both strange attractors and Julia sets typically have a fractal structure, and the fractal dimension can be calculated for them.

Discrete chaotic systems, such as the logistic map, can exhibit strange attractors whatever their dimensionality. Finite-dimensional linear systems are never chaotic; for a dynamical system to display chaotic behavior, it must be either nonlinear or infinite-dimensional.

The Lorenz attractor discussed below is generated by a system of three differential equations such as:. Five of the terms on the right hand side are linear, while two are quadratic; a total of seven terms.

Another well-known chaotic attractor is generated by the Rössler equations , which have only one nonlinear term out of seven.

Sprott [43] found a three-dimensional system with just five terms, that had only one nonlinear term, which exhibits chaos for certain parameter values.

Zhang and Heidel [44] [45] showed that, at least for dissipative and conservative quadratic systems, three-dimensional quadratic systems with only three or four terms on the right-hand side cannot exhibit chaotic behavior.

The reason is, simply put, that solutions to such systems are asymptotic to a two-dimensional surface and therefore solutions are well behaved.

In physics , jerk is the third derivative of position , with respect to time. As such, differential equations of the form. It has been shown that a jerk equation, which is equivalent to a system of three first order, ordinary, non-linear differential equations, is in a certain sense the minimal setting for solutions showing chaotic behaviour.

This motivates mathematical interest in jerk systems. Systems involving a fourth or higher derivative are called accordingly hyperjerk systems. A jerk system's behavior is described by a jerk equation, and for certain jerk equations, simple electronic circuits can model solutions.

These circuits are known as jerk circuits. One of the most interesting properties of jerk circuits is the possibility of chaotic behavior.

In fact, certain well-known chaotic systems, such as the Lorenz attractor and the Rössler map , are conventionally described as a system of three first-order differential equations that can combine into a single although rather complicated jerk equation.

Nonlinear jerk systems are in a sense minimally complex systems to show chaotic behaviour; there is no chaotic system involving only two first-order, ordinary differential equations the system resulting in an equation of second order only.

Here, A is an adjustable parameter. The output of op amp 0 will correspond to the x variable, the output of 1 corresponds to the first derivative of x and the output of 2 corresponds to the second derivative.

Similar circuits only require one diode [53] or no diodes at all. See also the well-known Chua's circuit , one basis for chaotic true random number generators.

Under the right conditions, chaos spontaneously evolves into a lockstep pattern. In the Kuramoto model , four conditions suffice to produce synchronization in a chaotic system.

Examples include the coupled oscillation of Christiaan Huygens ' pendulums, fireflies, neurons , the London Millennium Bridge resonance, and large arrays of Josephson junctions.

In the s, while studying the three-body problem , he found that there can be orbits that are nonperiodic, and yet not forever increasing nor approaching a fixed point.

Chaos theory began in the field of ergodic theory. Despite initial insights in the first half of the twentieth century, chaos theory became formalized as such only after mid-century, when it first became evident to some scientists that linear theory , the prevailing system theory at that time, simply could not explain the observed behavior of certain experiments like that of the logistic map.

What had been attributed to measure imprecision and simple " noise " was considered by chaos theorists as a full component of the studied systems.

The main catalyst for the development of chaos theory was the electronic computer. Much of the mathematics of chaos theory involves the repeated iteration of simple mathematical formulas, which would be impractical to do by hand.

Electronic computers made these repeated calculations practical, while figures and images made it possible to visualize these systems.

As a graduate student in Chihiro Hayashi's laboratory at Kyoto University, Yoshisuke Ueda was experimenting with analog computers and noticed, on November 27, , what he called "randomly transitional phenomena".

Yet his advisor did not agree with his conclusions at the time, and did not allow him to report his findings until Edward Lorenz was an early pioneer of the theory.

His interest in chaos came about accidentally through his work on weather prediction in He wanted to see a sequence of data again, and to save time he started the simulation in the middle of its course.

He did this by entering a printout of the data that corresponded to conditions in the middle of the original simulation. To his surprise, the weather the machine began to predict was completely different from the previous calculation.

Lorenz tracked this down to the computer printout. The computer worked with 6-digit precision, but the printout rounded variables off to a 3-digit number, so a value like 0.

This difference is tiny, and the consensus at the time would have been that it should have no practical effect.

However, Lorenz discovered that small changes in initial conditions produced large changes in long-term outcome.

In , Benoit Mandelbrot found recurring patterns at every scale in data on cotton prices. In , he published " How long is the coast of Britain?

Statistical self-similarity and fractional dimension ", showing that a coastline's length varies with the scale of the measuring instrument, resembles itself at all scales, and is infinite in length for an infinitesimally small measuring device.

In , Mandelbrot published The Fractal Geometry of Nature , which became a classic of chaos theory.

Yorke coiner of the term "chaos" as used in mathematics , Robert Shaw , and the meteorologist Edward Lorenz.

The following year Pierre Coullet and Charles Tresser published "Iterations d'endomorphismes et groupe de renormalisation", and Mitchell Feigenbaum 's article "Quantitative Universality for a Class of Nonlinear Transformations" finally appeared in a journal, after 3 years of referee rejections.

In , Albert J. Feigenbaum for their inspiring achievements. There, Bernardo Huberman presented a mathematical model of the eye tracking disorder among schizophrenics.

In , Per Bak , Chao Tang and Kurt Wiesenfeld published a paper in Physical Review Letters [80] describing for the first time self-organized criticality SOC , considered one of the mechanisms by which complexity arises in nature.

Alongside largely lab-based approaches such as the Bak—Tang—Wiesenfeld sandpile , many other investigations have focused on large-scale natural or social systems that are known or suspected to display scale-invariant behavior.

Although these approaches were not always welcomed at least initially by specialists in the subjects examined, SOC has nevertheless become established as a strong candidate for explaining a number of natural phenomena, including earthquakes , which, long before SOC was discovered, were known as a source of scale-invariant behavior such as the Gutenberg—Richter law describing the statistical distribution of earthquake sizes, and the Omori law [81] describing the frequency of aftershocks , solar flares , fluctuations in economic systems such as financial markets references to SOC are common in econophysics , landscape formation, forest fires , landslides , epidemics , and biological evolution where SOC has been invoked, for example, as the dynamical mechanism behind the theory of " punctuated equilibria " put forward by Niles Eldredge and Stephen Jay Gould.

Given the implications of a scale-free distribution of event sizes, some researchers have suggested that another phenomenon that should be considered an example of SOC is the occurrence of wars.

In the same year, James Gleick published Chaos: Making a New Science , which became a best-seller and introduced the general principles of chaos theory as well as its history to the broad public, though his history under-emphasized important Soviet contributions.

Alluding to Thomas Kuhn 's concept of a paradigm shift exposed in The Structure of Scientific Revolutions , many "chaologists" as some described themselves claimed that this new theory was an example of such a shift, a thesis upheld by Gleick.

The availability of cheaper, more powerful computers broadens the applicability of chaos theory. Currently, chaos theory remains an active area of research, [83] involving many different disciplines such as mathematics , topology , physics , [84] social systems , [85] population modeling , biology , meteorology , astrophysics , information theory , computational neuroscience , pandemic crisis management , [17] [18] etc.

Although chaos theory was born from observing weather patterns, it has become applicable to a variety of other situations.

Some areas benefiting from chaos theory today are geology , mathematics , microbiology , biology , computer science , economics , [87] [88] [89] engineering , [90] [91] finance , [92] [93] algorithmic trading , [94] [95] [96] meteorology , philosophy , anthropology , [15] physics , [97] [98] [99] politics , [] [] population dynamics , [] psychology , [14] and robotics.

A few categories are listed below with examples, but this is by no means a comprehensive list as new applications are appearing. Chaos theory has been used for many years in cryptography.

In the past few decades, chaos and nonlinear dynamics have been used in the design of hundreds of cryptographic primitives.

These algorithms include image encryption algorithms , hash functions , secure pseudo-random number generators , stream ciphers , watermarking and steganography.

Robotics is another area that has recently benefited from chaos theory. Instead of robots acting in a trial-and-error type of refinement to interact with their environment, chaos theory has been used to build a predictive model.

For over a hundred years, biologists have been keeping track of populations of different species with population models. Most models are continuous , but recently scientists have been able to implement chaotic models in certain populations.

While a chaotic model for hydrology has its shortcomings, there is still much to learn from looking at the data through the lens of chaos theory.

Fetal surveillance is a delicate balance of obtaining accurate information while being as noninvasive as possible. Better models of warning signs of fetal hypoxia can be obtained through chaotic modeling.

In chemistry, predicting gas solubility is essential to manufacturing polymers , but models using particle swarm optimization PSO tend to converge to the wrong points.

An improved version of PSO has been created by introducing chaos, which keeps the simulations from getting stuck. In quantum physics and electrical engineering , the study of large arrays of Josephson junctions benefitted greatly from chaos theory.

Until recently, there was no reliable way to predict when they would occur. But these gas leaks have chaotic tendencies that, when properly modeled, can be predicted fairly accurately.

Glass [] and Mandell and Selz [] have found that no EEG study has as yet indicated the presence of strange attractors or other signs of chaotic behavior.
