2. A naturally occurring group of interacting, interrelated, or interdependent elements, forming a complex whole, existing far from equilibrium, that have evolved together through time, forming a dynamic network where everything is connected to everything else by positive and negative feedback, such that a change in one component affects the states of the other components, exhibiting sensitive dependence, fractal organization, and avalanche behavior that follows a power-law distribution.” What is a System? Clarification Five Again Much of our difficulty with thinking about systems is tied up with,... How we think about systems. This a problem of history, and philosophy, and psychology.

4. The pendulum is an important system because throughout history it has been the emblem of classical mechanics and the epitome of clockwork regularity. In the 19th century the great French mathematician Laplace said: If we were to know with precision the positions and speeds of all the particles in the universe then we could predict the future with certainty. Pierre Simon de Laplace (1749-1827) The Pendulum as a Limit Cycle

5. If that enabled us to predict the succeeding situation with the same approximation, that is all we require, and we should say that the phenomenon had been predicted, that it is governed by laws. But it is not always so; it may happen that small differences in the initial conditions produce very great ones in the final phenomena. A small error in the former will produce an enormous error in the latter. Prediction becomes impossible, and we have the fortuitous phenomenon. Yet, Henir Poincare in a 1903 essay titled “Science and Method” said this: Henri Poincaré (1854-1912) If we knew exactly the laws of nature and the situation of the universe at the initial moment, we could predict exactly the situation of that same universe at a succeeding moment. but even if it were the case that the natural laws had no longer any secret for us, we could still only know the initial situation approximately. The Pendulum as a Chaotic System

6. This tension between the need for complete predictability and certainty, and the real world in which we live - which is anything but predictable - has always existed. But, the question comes down to, does the real world work as classical science says it does? Or, more directly ? How can we test these ideas ? Run Pendulum Can a system that behaves like a classic pendulum - swinging with complete regularity - evolve and change? And, what would be required for it to evolve and change?

9. Have you ever seen a child take apart a favorite toy? Did you then see the little one cry after realizing he could not put all the pieces back together again? Well, here is a secret that never makes the headlines: We have taken apart the universe and have no idea how to put it back together. After spending trillions of research dollars to disassemble nature in the last century, we are just now acknowledging that we have no clue how to continue—except to take it apart further. Reductionism was the driving force behind much of the twentieth century's scientific research.

10. 1.Reductionist1.Holistic and Emergent Classical Science Evolutionary Systems Classical Science and Evolutionary Systems Science To understand a system we must take it apart and understand the pieces. The whole is more than the sum of the parts; the whole must therefore be studied in its own right. 2. Linear2. Non-Linear A system where the effects are proportional to the causes. Of or relating to a system of equations whose effects are not proportional to their causes - sensitive dependence. Such a set of equations can be chaotic. 3. Clear Boundaries3. Diffuse Boundaries The best system is self-contained, isolated, complete in itself so it can be understood without distractions or outside influence. Organic. Coevolving. Because complex systems are open they must exchange energy and information with the surroundings–the environment. Therefore, boundaries are not distinct.

11. 4. Discrete Solutions4. Qualitative Numeric solutions—answers. There is a right answer, and the more precision we have the better. The devil is in the details. 5. Centralized Control Straight forward cause and effect relationships, or clear chains of command. The interactions among the agents are beyond logical analysis, but the outcome of the interactions produce patterns easily observed and compared. The eye is quicker than the mind. 5. Interconnected Systems Every component affects every other component in a complex network of positive and negative feedback. There is no centralized control.

12. “It has been said that if the universe is an elephant, then linear theory (classical science) can only be used to describe the last molecule in the tail of the elephant and chaos (read complex systems) theory must be used to understand the rest. Or, in other words, almost all interesting real-world systems are described by non- linear (complex) systems.” OK, OK. But, really, just how common are these complex systems?

13. "In my graduate school courses, we were always taught that large nonlinear systems were monsters, practically impossible to solve. Yet here was one and it was beautiful. It didn't even seem that hard to understand." Steve Strogatz, 2003, Sync: The Emerging Science of Spontaneous Order What Self Organized Criticality and Deterministic Chaos are saying is abhorrent to classical science – the science taught in most classrooms.

14. So far, all this is well and good, but it still does not provide explainability for the fundamental problem – For example, how does a large city operate without central planning? Millions of people, thousands of stores and merchants. All working more or less independently, each looking after their own selfish interests. Yet the store shelves are always full. The Problem....how do systems become more complex with time, without resorting to a teleological argument.....By what mechanism does complexity increases with time.

15. The Problem of Problems General Solutions to the Problem 3. Naturalism An Inquiry into the Nature and Causes of the Wealth of Nations, 1776 As every individual, therefore, endeavours as much as he can both to employ his capital in the support of domestic industry, and so to direct that industry that its produce may be of the greatest value; every individual necessarily labours to render the annual revenue of the society as great as he can. He generally, indeed, neither intends to promote the public interest, nor knows how much he is promoting it. By preferring the support of domestic to that of foreign industry, he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention. Nor is it always the worse for the society that it was no part of it. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it.

16. The Problem of Problems General Solutions to the Problem 3. Self Organization (the new Naturalism) Self-organization is a process where the organization of a system spontaneously increases without this increase being controlled by the environment or an encompassing or otherwise external system. A process of evolution where the effect of the environment is minimal, i.e. where the development of new, complex structures takes place primarily in and through the system itself. Prigogine called systems which continuously export entropy in order to maintain their organization dissipative structures. It is an “invisible hand”, like the invisible hand of commerce. But, that is like saying the “invisible hand of God.” It puts it in the realm of the supernatural, or magic. Are there any systems or natural mechanisms to explain self organization?

22. Sensitive Dependence in Cellular Automata

24. Power-Law Relationships in Cellular Automata Run an random array until it stops, add a live cell at random, run again until it stops. Avalanche size is the number of generations from initiation until it stops. Most avalanches last only one or a few generations; others may last hundreds of generations. Plotted up the avalanches follow a power-law meaning Cellular Automata (with optimum local rules) are Self Organized Critical systems.

25. So, to refine our definition: A “system” is a group of naturally occurring interacting, interrelated, or interdependent elements, forming a complex whole that have evolved together through time, forming a dynamic network where everything is connected to everything else by positive and negative feedback, exhibiting:  sensitive dependence,  and avalanche behavior that follows a power-law distribution.  fractal organization, What is a System? Clarification Six existing far from equilibrium, (self organized by bottom-up processes) such that a change in one component affects the states of the other components,

26. It is all about how the lithosphere, hydrosphere, atmosphere, and biosphere connect – the links among them - and the positive and negative feedback relations among them that must be understood. Many of the ideas we need to understand, and we need to learn, have not been taught to us. But, we have to begin somewhere and this is as good a place as any, so let’s start here. The Earth and Everything On It Are A System! They cannot be understood in reductionist terms They cannot be understood in linear terms. They cannot be understand through only 1 or 2 disciplines.
