Far better solutions are needed. Fortunately, economic science has not stood entirely still. A new paradigm has emerged in the past twenty years from several schools of thought, including behavioral economics and complexity theory, among others. This new thinking comes with a healthy dose of humility—practitioners in many cases acknowledge the limitations of what is possible with the tools at hand. The new schools avoid the triumphalism of Keynes’s claim to a “general theory” and Friedman’s dictum that inflation is “always and everywhere” monetary. The most promising new school is complexity theory. Despite the name, complexity theory rests on straightforward foundations. The first is that complex systems are not designed from the top down. Complex systems design themselves through evolution or the interaction of myriad autonomous parts.

When you apply this paradigm to finance, you begin to see where the currency wars are headed. Complexity theory has a strong empirical foundation and has had wide application in a variety of natural and man-made settings, including climate, seismology and the Internet. Significant progress has been made in applying complexity to capital and currency markets. However, a considerable challenge arises when one considers the interaction of human behavior and market dynamics. The complexity of human nature sits like a turbocharger on top of the complexity of markets. Human nature, markets and civilization more broadly are all complex systems nested inside one another like so many Russian matryoshka dolls. An introduction to behavioral economics will provide a bridge to a broader consideration of complexity theory and how underlying dynamics may determine the fate of the dollar and the endgame in the currency wars.

The best illustration of immanent self-organization, as far as I know, is still jazz group improvisation, to which chapter 1 will add a number of others from a variety of fields (including science, games, and ethology); the concept of immanence they illustrate, in any case, is key to nomadism and nomadology, as first defined by Deleuze and Guattari.24 Some of its roots lie in complexity theory and nonlinear mathematics, which have both formalized and reinforced long-standing impressions that order can and often does arise in systems spontaneously, without being imposed by some transcendent instance standing above or outside the system. Complexity theory supports both the nontotalized view of society and the nonlinear view of history informing nomadology.25 The discovery of emergent self-organization seemed to belie the second law of thermodynamics, according to which entropy is supposed to increase—in any closed system operating close to equilibrium, that is. But the fields to which complexity theory was most dramatically applied were not closed systems and were nowhere near equilibrium: life on earth, for instance, receives practically immeasurable amounts of energy from the sun and thus represents a classic case of negentropy or syntropy rather than en­ tropy.

But the fields to which complexity theory was most dramatically applied were not closed systems and were nowhere near equilibrium: life on earth, for instance, receives practically immeasurable amounts of energy from the sun and thus represents a classic case of negentropy or syntropy rather than en­ tropy. As Stuart Kauffmann (among others) has shown, starting from al­ most trivially simple mathematical models, spontaneous self-organization emerges in all kinds of systems, from inorganic molecule clusters to cells and organisms, to ecosystems, economies, and cultures.26 Of course, de­ bates about the sources or bases of social organization date back to the dawn of philosophy, but complexity theory gave new impetus and added credence to conceiving of various kinds of social order as immanently self­ organizing, and this becomes a key component of the concept of nomad citizenship. The main components of the concept of free-market communism, mean­ while, come from more disparate sources, starting with theories of the free market and Marxist theory itself. Drawing components from such ideo­ logically opposed theories, the construction of the paradoxical concept of free-market communism will clearly have to be quite selective.

But first, it is impor­ tant to note that the distinction presented here (derived from A Thousand Plateaus) between two kinds of science seriously complicates the stark distinction between science and philosophy discussed earlier (and derived from What Is Philosophy?). The fact is that Deleuze and Guattari were very well versed and extremely interested in developments in contempo­ rary science inspired by nonlinear mathematics and complexity theory, as I mentioned earlier.60 Compared to classical mechanics, for example (which may represent the epitome of controlled-variable empirical science), many contemporary sciences pay far more attention to the conditions of emer­ gence of their objects of study, to the virtual intensive processes that give rise to actual objects. There is therefore considerable overlap between the contributions of these sciences and what Jeffrey Bell has called Deleuze’s “historical ontology”—the view he derives from Bergson and Leibniz (among others), according to which each and everything is understood to be simply the result (the “contraction”) of its virtual conditions of actual­ ization or emergence.61 Ultimately, however, the main thrust of Deleuze and Guattari’s philosophy is not ontological: it is political.

This book limns the most imminent threats to the dollar, likely to play out in the next few years, which are financial warfare, deflation, hyperinflation, and market collapse. Only nations and individuals who make provision today will survive the maelstrom to come. In place of fallacious, if popular, methods, this book considers complexity theory to be the best lens for viewing present risks and likely outcomes. Capital markets are complex systems nonpareil. Complexity theory is relatively new in the history of science, but in its sixty years it has been extensively applied to weather, earthquakes, social networks, and other densely connected systems. The application of complexity theory to capital markets is still in its infancy, but it has already yielded insights into risk metrics and price dynamics that possess greater predictive power than conventional methods. As you will see in the pages that follow, the next financial collapse will resemble nothing in history.

If the United States faces severe deflation again, the antidote of dollar devaluation against gold will be the same, because there is no other solution when printing money fails. ■ Market Collapse The prospect of a market collapse is a function of systemic risk independent of fundamental economic policy. The risk of market collapse is amplified by regulatory incompetence and banker greed. Complexity theory is the proper framework for analyzing this risk. The starting place in this analysis is the recognition that capital markets exhibit all four of complex systems’ defining qualities: diversity of agents, connectedness, interdependence, and adaptive behavior. Concluding that capital markets are complex systems has profound implications for regulation and risk management. The first implication is that the proper measurement of risk is the gross notional value of derivatives, not the net amount.

The Sraffian scorecard Though the Sraffian school was fairly influential up until 2000, there have been few developments in it since, certainly in comparison to the growth in post-Keynesian economics since that date. Complexity theory and Econophysics Complexity theory is not so much a school of thought in economics as a group of economists who apply what is popularly known as ‘chaos theory’ to economic issues. Since the first edition of this book, there has also been an enormous growth in the number of physicists taking an active interest in economics and finance, and this new school of ‘Econophysics’ has largely subsumed the complexity theory approach. The concept of chaos itself was first discovered in 1899 by the French mathematician Henri Poincaré. However, knowledge of it languished until the mid-1960s because it could not be fully explored until after the invention of computers.

Modeling Minsky Minsky did develop a mathematical model of a financially driven business cycle in his PhD, which resulted in the one paper he ever had published in a mainstream economic journal, the American Economic Review (Minsky 1957).3 But the model was unsatisfactory for a number of reasons, and he subsequently abandoned it to stick with predominantly verbal reasoning. Minsky’s failure to develop a satisfactory mathematical model was partly due to bad timing: the 1950s pre-dated the development of complexity theory, which made trying to build a model of his hypothesis virtually impossible. Minsky simply added a financial dimension to the dominant linear trade cycle model of the day, which was a particularly unsuitable foundation for his hypothesis.4 In 1993, well after complexity theory had developed, I built my initial Minsky model using the far more suitable foundation of the cyclical growth model developed by the non-neoclassical economist Richard Goodwin (Goodwin 1967). Goodwin’s model considered the level of investment and the distribution of income in a simple two-class model of capitalism.

You would do as well to consult a Ouija board as an economist who rigorously follows economic theory when giving advice. The Sonnenschein-Mantel-Debreu result is one of many that have effectively split the caste of mathematical economists into two sects. One pretends that business as usual can continue, despite the presence of this (and many other) fallacies in the creed. The other is dabbling in alternative religions – such as complexity theory, or evolutionary economics. Sadly, the uninformed majority of the profession believes that the first sect is the bearer of the true religion, and that the members of the second sect have betrayed the faith. A more accurate analogy is that the dabblers in alternative religions are experiencing the first flushes of adolescence, while the majority of the profession remains mired in infancy. Clearly, the Benthamite ambition to portray society as simply an aggregate of its individual members is a failure.

In Pursuit of the Traveling Salesman: Mathematics at the Limits of Computation by William J. Cook


complexity theory, computer age, four colour theorem, index card, John von Neumann, linear programming, NP-complete, p-value, RAND corporation, Richard Feynman, Richard Feynman, traveling salesman, Turing machine

What sets the traveling salesman problem apart is the fact that despite decades of research by top applied mathematicians around the world, in general it is not known how to significantly improve upon simple bruteforce checking. It is a real possibility that there may never exist an efficient method that is guaranteed to solve every example of the problem. This is a xii Preface deep mathematical question: is there an efficient solution method or not? The topic goes to the core of complexity theory concerning the limits of feasible computation. For the stouthearted who would like to tackle the general version of the problem, the Clay Mathematics Institute will hand over a $1,000,000 prize to anyone who can either produce an efficient method or prove that this is impossible. The complexity question that is the subject of the Clay Prize is the Holy Grail of traveling-salesman-problem research and we may be far from seeing its resolution.

Thousands of LP users nonetheless go ahead and include such restrictions in their models everyday, unable to resist the flexibility that integer-only variables bring to the table. The extended framework is known as integer programming, or IP for short. Dantzig himself was the first to document how versatile integer programming can be. In a paper that is fundamental in both the field of optimization and the field of complexity theory, he showed how each member of a long list of important optimization problems can be modeled as an IP problem.29 Dantzig described his work as follows in his 1963 LP book.30 Linear Programming Figure 5.19 Four-coloring of a graph. Our purpose is systematically to review and classify problems that can be reduced to linear programs, some or all of whose variables are integer valued. We shall show that a host of difficult, indeed seemingly impossible, problems of a nonlinear, nonconvex, and combinatorial character are now open for direct attack.

Why would he expect his polyhedral methods to fail on the salesman, after working spectacularly in other cases? Edmonds was coy with his explanation, noting only that it was a legitimate possibility that no good algorithm exists. Four years after this bet, Stephen Cook and Richard Karp developed their theory placing the question in the larger world of P vs. N P. The Complexity Classes Mathematicians like to keep things tidy, and in the case of complexity theory this has led to a focus on decision problems, that is, a focus on problems having yes or no answers. So, for example, does a graph have a Hamiltonian circuit? Yes or no. Or, given a set of cities, is there a tour of length less than 1,000 miles? Yes or no.7 Among decision problems, Richard Karp introduced the short notation P to denote those that have good algorithms. Formally, P is the class of problems that can be solved in polynomial time on a single-tape Turing machine, that is, if n is the number symbols on the input tape, then the machine is guaranteed to halt after a number of steps that is at most C times nk , for some power k and some constant C .

The Golden Ticket: P, NP, and the Search for the Impossible by Lance Fortnow

The most prestigious computer science journal receives a steady stream of papers claiming to resolve the P versus NP question and has a specific policy for those papers: The Journal of the ACM frequently receives submissions purporting to solve a long-standing open problem in complexity theory, such as the P/NP problem. Such submissions tax the voluntary editorial and peer-reviewing resources used by JACM, by requiring the review process to identify the errors in them. JACM remains open to the possibility of eventual resolution of P/NP and related questions, and continues to welcome submissions on the subject. However, to mitigate the burden of repeated resubmissions of incremental corrections of errors identified during editorial review, JACM has adopted the following policy: No author may submit more than one paper on the P/NP or related long-standing questions in complexity theory in any 24 month period, except by invitation of the Editor-in-Chief. This applies to resubmissions of previously rejected manuscripts.

The Association for Computing Machinery is a major society serving computing researchers and professionals, and Communications is the society’s main magazine devoted to articles of interest for that community. At first I tried to push the article onto another computer scientist, but eventually relented. As Moshe put it to me, “If physicists write popular articles (and books) about string theory, we should be able to explain what complexity theory has accomplished, I’d hope.” I wrote the article, aiming for the Communications audience, not just about the status of the P versus NP problem, which can be summarized as “still open,” but about how people deal with hard problems. “The Status of the P versus NP Problem” was published in the September 2009 issue and quickly became the most downloaded article in the Communications’ history. The P versus NP problem remained a story to be told, and the popularity of the article suggested the time was right to tell this story, not just to scientists but to a much broader audience.

Chapter 4 The quotation from Cook is actually a paraphrase in modern terminology of the original quotation from his seminal paper. The original reads as follows: The theorems suggest that {tautologies} is a good candidate for an interesting set not in L*, and I feel it is worth spending considerable effort trying to prove this conjecture. Such a proof would be a major breakthrough in complexity theory.

Deep Survival: Who Lives, Who Dies, and Why by Laurence Gonzales


business climate, butterfly effect, complexity theory, Edward Lorenz: Chaos theory, impulse control, Lao Tzu, loose coupling, Louis Pasteur, V2 rocket

The theory of self-organized criticality, sometimes called Complexity theory, was developed hard on the heels of chaos theory by some of the same people. It asked and suggested answers to questions as fundamental as: Where does order come from? How do you reconcile it with the second law of thermodynamics, which says that everything is heading toward more disorder? In a sense, complexity was an extension of the thinking that gave rise to chaos theory; indeed, it was often referred to as existing at “the edge of chaos.” (There has also been strong objection to linking complexity and chaos and to using the term “complexity.”) Like chaos theory, complexity theory postulated “upheaval and change and enormous consequences flowing from trivial-seeming events—and yet with a deep law hidden beneath.” Complexity theory is a bold attempt to explain everything all at once, and so far it’s done a better job in some ways than either Einstein’s relativity theory or Niels Bohr’s quantum mechanics did.

He failed to anticipate the interaction of forces that would result from his stepping into a stream and flooding his boots. In moments, his feet froze solid. Now under stress, he failed to take in new information: In his haste, he built his fire beneath a tree that was laden with snow. It was one of those nonlinear kickback systems that was tightly coupled and that magnified trouble when upset. The Sand Pile Effect. London described all this long before chaos or complexity theory had been developed. His story touches on the most important elements of surviving in a spare and systematic manner: Each bough was fully freighted. Each time he had pulled a twig [from the tree] he had communicated a slight agitation to the tree—an imperceptible agitation, so far as he was concerned, but an agitation sufficient to bring about the disaster. High up in the tree one bough capsized its load of snow.

In a world governed by an ineluctable order, which pushes through Newtonian physics, Einsteinian relativity, thermodynamics, and quantum theory with all the certainty of gravity or any other encroaching natural law, nothing can truly be said to happen by chance, which is just a word we invented to explain the troublesome boundary between order and chaos. Fate, then, turns out to be the struggle, the tension, between the natural law that dictates that everything should proceed toward disorder (entropy) and the natural law that dictates that everything should be self-organizing (complexity theory). If those are, indeed, the two overarching natural laws, then everything becomes clear and we go forward into the past to find the Chinese concept of yin and yang. Certainly, my father’s survival did not end with his falling from the sky. I watched it take shape, even as it shaped me and my world. It began there, a man with broken legs and broken arms and broken feet and ribs, his nose stuck back on almost as an afterthought by a boy who happened by as he was weeping.

In 1995 Brad Hoyt, a senior project manager at Senco, a Cincinnati toolmaker, recalled a scenario-planning session with Stewart Brand: “He changed my whole life in one scenario planning session. He asked whether we’d heard about complexity theory. . . . Little did I know he’s on the board of the Santa Fe Institute.”36 Over the next year, Hoyt reported reading another dozen books on complexity and came to use complexity theory as a guide to “thinking about the housing industry and other ecosystems affecting Senco.” For executives like Hoyt, the systems-oriented rhetoric of complexity theory, buttressed by the cultural legitimacy of Stewart Brand, offered a compelling framework within which to understand the topsy-turvy economy of the late 1980s and early 1990s. Even at firms with more skeptical executives, GBN quietly brought into the corporate world people and publications that both promoted and modeled a networked sensibility.

I try splitting the difference; then we both jump back in at the same time. A guy can’t catch a break—or more accurately might be he can’t get someone else to catch his breaks. Somehow the timing ballet that feels like second nature in person seems consistently—here, and as a general rule—to break down over the phone. I do the best I can, but it feels, somehow, solitary— Computability Theory vs. Complexity Theory The first branch of computer science theory was what’s come to be known as “computability theory,” a field that concerns itself with theoretical models of computing machines and the theoretical limits of their power. It’s this branch of theory in which Turing made some of his greatest contributions: in the 1930s and ’40s, physical computing machines were so fledgling that it made sense to think idealistically about them and the purely theoretical extents and limits of their potential.

Similarly, computer data encryption hinges on the fact that prime numbers can be multiplied into large composite numbers faster than composite numbers can be factored back into their primes. The two operations are both perfectly computable, but the second happens to be exponentially slower—making it intractable. This is what makes online security, and online commerce, possible. The next generation of computer theorists after Turing, in the 1960s and ’70s, began to develop a branch of the discipline, called complexity theory, that took such time-and-space constraints into account. As computer theorist Hava Siegelmann of the University of Massachusetts explains, this more “modern” theory deals not only “with the ultimate power of a machine, but also with its expressive power under constraints on resources, such as time and space.” Michael Sipser’s textbook Introduction to the Theory of Computation, considered one of the bibles of theoretical computer science, and the textbook I myself used in college, cautions, “Even when a problem is decidable and thus computationally solvable in principle, it may not be solvable in practice if the solution requires an inordinate amount of time or memory.”

In a purely grammatical view of language, the words “uh” and “um” are meaningless. Their dictionary entries would be blank. But note that the idealized form of language which Chomsky makes his object of study explicitly ignores “such grammatically irrelevant conditions as memory limitations … [and] actual performance.” In other words, Chomsky’s theory of language is the computability theory of Turing’s era, not the complexity theory that followed. Very similarly idealized, as it happens, are chatbots’ models of language. Yet it turns out—just as it did in computer science—that there’s a tremendous amount happening in the gap between the “ideal” process and the “actual performance.” As a human confederate, I planned to make as much of this gap as possible. Satisficing and Staircase Wit Economics, historically, has also tended to function a bit like computability theory, where “rational agents” somehow gather and synthesize infinite amounts of information in the smallest of jiffies, then immediately decide and act.

In fact, there is a million dollar prize offered by Clay Mathematics Institute for the first person to give a proof of whether or not P is the same set as NP, some people conjecture that the set of problems that quantum computers can solve in polynomial time contains all of P and also some problems not in P, but not all of NP. But this is a conjecture. The proof would have to show that P is not equal to NP. This area of the theory of computation dealing with the amount of time and storage needed to do computations based on the size of the input is known as complexity theory. These questions are not just of theoretical interest, but have important practical applications. Much of internet commerce requires secure ways of encrypting information. However, many of the current methods of encryption are based on methods that are conjectured, but not proven, to be exponentially difficult to crack. It would be nice to have a proof that our internet banking is safe! Quantum computers and non-deterministic Turing machines may be faster in certain instances, but they are not computationally more powerful than Turing machines.

The contract calls for individuals to surrender all rights (except self-defense) to the sovereign who, like the biblical Leviathan, is responsible only to God. Compared to a war of all against all, a sovereign presiding over the state is far superior and forms the basis for a rational society in which peace and prosperity are available on a mass scale. I have oversimplified the steps in Hobbes' complex theory, but the point is that his reasoning was Euclidean and his system mechanical. He began with metaphysical first principles and ended with an entire social structure. Moreover, because many political theorists consider Hobbes the most influential thinker of the modern age, the connection Hobbes made between politics and science is not dead yet. Science and culture are interactive, not separate and independent, despite attempts by scientists to keep them separate.

Like the alien abduction phenomenon, these are products of the mind, not reality. They are social follies and mental fantasies, driven by a curious phenomenon called the feedback loop. A Witch Craze Feedback Loop Why should there be such movements in the first place, and what makes these seemingly dissimilar movements play out in a similar manner? A helpful model comes from the emerging sciences of chaos and complexity theory. Many systems, including social systems like witch crazes, self-organize through feedback loops, in which outputs are connected to inputs, producing change in response to both (like a public-address system with feedback, or stock market booms and busts driven by flurries of buying and selling). The underlying mechanism driving a witch craze is the cycling of information through a closed system.

And both received the ultimate endorsement of the conservative intelligentsia when they were invited by William F. Buckley to join his team in a television PBS debate on evolution and creation. (Buckley's PBS Firing Line show aired in December 1997, where it was resolved that "Evolutionists should acknowledge creation." The debate was emblematic of the new creationism, employing new euphemisms such as "intelligent-design theory," "abrupt appearance theory," and "initial complexity theory," where it was argued that the "irreducible complexity" of life proves it was created by an intelligent designer, or God.) For my money, however, the quintessential example of a smart person believing a weird thing is Frank Tipler, a professor of theoretical mathematics at Tulane University and one of the world's leading cosmologists and global general relativists. Tipler enjoys close friendships with such luminaries as Stephen Hawking, Roger Penrose, and Kip Thorne.

In my picture the genome encodes this inductive bias, programs that execute, interacting with sensory data, to learn. The learning so innately programmed appears quite automatic, reliably resulting in creatures with similar abilities provided that they are allowed interaction with the world during development. Complexity theory suggests that learning is a hard problem, requiring vast computation to extract structure. Yet we learn so fast that we do not have time to do the requisite computation. This is possible only because creatures are preprogrammed to extract specific kinds of meaning. The bulk of the requisite computation, and thus the guts of the process from the point of view of complexity theory, went into the evolution of the genome. Empirical evidence shows that creatures are in fact programmed with specific inductive biases. If a rat is shocked once at a specific point in its maze, it will avoid that corner.

Natural Intelligence Turing argued compellingly that whatever is happening in the brain, it could be simulated in detail by a computer running the right software. Thus thoughts must be isomorphic to some particular computations. Turing's thesis gives us a precise language which we can use to discuss and model thought, the language of computer programs. This thesis, however, left us with some puzzles. A first important one is: what about this particular code causes it to understand? A second important one is: given that complexity theory has indicated that many computations are inherently time consuming, how does the mind work so amazingly fast? Computational learning theory has explained generalization as arising from Occam's razor. The most studied context is concept learning, where one sees a series of classified examples, and desires to learn a function that will predict correctly whether new examples are examples of the concept or not.

That is why many fewer resources are now devoted to this kind of meteorology, or to economic forecasting models. Some scientists have attempted to establish general principles that might be relevant to all problems of organized complexity. The world center for this research is a spin-off from the U.S. nuclear research establishment at Los Alamos, located at Santa Fe in the mountains ofNew Mexico, and analysis undertaken there goes under the heading of complexity theory. 21 The hope is not to predict the future, but to gain a better understanding of the general properties of complex systems. We cannot know what the weather will be like next June 4. But meteorologists can give an indication of the average temperature to be expected and the likely range. They can assess the probability of rain and make contingent predictions-it is more likely to be sunny on June 4 if it was sunny on June 3.

Simon's example parallels complexity theorist Stuart Kauffman's description of what he calls fitness landscapes. 26 Kauffman is interested in the general mathematical structure of complex systems. Height above sea level in Simon's example might equally be a measure of how well a species is adapted to its environment, or how effectively scarce resources are allocated between competing ends. Kauffman's conjecture is that common models and principles of self-organization describe phenomena as diverse as the emergence of life and the construction of social order. Complexity theory today occupies a strange, perhaps unique, position within the scientific canon. It has attracted the attention of scientists of exceptional distinction and creativity, yet stands somewhat outside the mainstream of professional knowledge. Economists are particularly skeptical. 27 As I shall describe in chapter 28, the analogy with physics is central to their thinking. The most widely used model of spontaneous order in economics follows the structure of "simple system" physical models.

Furthermore, the idea that a completely deterministic process can produce results that are completely unpredictable is of great importance, as it provides an explanation for how the world can be inherently unpredictable while still based on fully deterministic rules.68 However, I am not entirely surprised by the idea that simple mechanisms can produce results more complicated than their starting conditions. We've seen this phenomenon in fractals, chaos and complexity theory, and self-organizing systems (such as neural nets and Markov models), which start with simple networks but organize themselves to produce apparently intelligent behavior. At a different level, we see it in the human brain itself, which starts with only about thirty to one hundred million bytes of specification in the compressed genome yet ends up with a complexity that is about a billion times greater.69 It is also not surprising that a deterministic process can produce apparently random results.

Simultaneously we are rapidly accumulating data on the precise characteristics and dynamics of the constituent parts and systems of the brain, ranging from individual synapses to large regions such as the cerebellum, which comprises more than half of the brain's neurons. Extensive databases are methodically cataloging our exponentially growing knowledge of the brain.3 Researchers have also shown they can rapidly understand and apply this information by building models and working simulations. These simulations of brain regions are based on the mathematical principles of complexity theory and chaotic computing and are already providing results that closely match experiments performed on actual human and animal brains. As noted in chapter 2, the power of the scanning and computational tools needed for the task of reverse engineering the brain is accelerating, similar to the acceleration in technology that made the genome project feasible. When we get to the nanobot era (see "Scanning Using Nanobots" on p. 163), we will be able to scan from inside the brain with exquisitely high spatial and temporal resolution.4 There are no inherent barriers to our being able to reverse engineer the operating principles of human intelligence and replicate these capabilities in the more powerful computational substrates that will become available in the decades ahead.

While there is a great deal of stochastic (random within carefully controlled constraints) process in every aspect of the brain, it is not necessary to model every "dimple" on the surface of every dendrite, any more than it is necessary to model every tiny variation in the surface of every transistor in understanding the principles of operation of a computer. But certain details are critical in decoding the principles of operation of the brain, which compels us to distinguish between them and those that comprise stochastic "noise" or chaos. The chaotic (random and unpredictable) aspects of neural function can be modeled using the mathematical techniques of complexity theory and chaos theory.16 ·The brain uses emergent properties. Intelligent behavior is an emergent property of the brain's chaotic and complex activity. Consider the analogy to the apparently intelligent design of termite and ant colonies, with their delicately constructed interconnecting tunnels and ventilation systems. Despite their clever and intricate design, ant and termite hills have no master architects; the architecture emerges from the unpredictable interactions of all the colony members, each following relatively simple rules.

Recent efforts by NASA and by Rundle to measure fault stress through remote sensing systems like GPS satellites have shown some promise.76 Although the efforts are crude for the time being, there is potential to increase the amount of data at seismologists’ disposal and get them closer to understanding the root causes of earthquakes. • • • These methods may eventually produce some forward progress. If success in earthquake prediction has been almost nonexistent for millennia, the same was true for weather forecasting until about forty years ago. Or it may be that as we develop our understanding of complexity theory—itself a very new branch of science—we may come to a more emphatic conclusion that earthquakes are not really predictable at all. Either way, there will probably be some failed predictions first. As the memory of our mistakes fades, the signal will again seem to shimmer over the horizon. Parched for prediction we will pursue it, even if it is a mirage. 6 HOW TO DROWN IN THREE FEET OF WATER Political polls are dutifully reported with a margin of error, which gives us a clue that they contain some uncertainty.

Quantum mechanics, that brilliantly successful flagship theory of modern science, is deeply mysterious and hard to understand. Eastern mystics have always been deeply mysterious and hard to understand. Therefore eastern mystics must have been talking about quantum theory all along. Similar mileage is made of Heisenberg’s Uncertainty Principle (‘Aren’t we all, in a very real sense, uncertain?’), Fuzzy Logic (‘Yes, it’s OK for you to be fuzzy too’), Chaos and Complexity Theory (the butterfly effect, the platonic, hidden beauty of the Mandelbrot Set – you name it, somebody has mysticized it and turned it into dollars). You can buy any number of books on ‘quantum healing’, not to mention quantum psychology, quantum responsibility, quantum morality, quantum aesthetics, quantum immortality and quantum theology. I haven’t found a book on quantum feminism, quantum financial management or Afro-quantum theory, but give it time.

Unweaving the Rainbow by Richard Dawkins


Any sufficiently advanced technology is indistinguishable from magic, Arthur Eddington, complexity theory, correlation coefficient, David Attenborough, discovery of DNA, double helix, Douglas Engelbart, I think there is a world market for maybe five computers, Isaac Newton, Jaron Lanier, Mahatma Gandhi, music of the spheres, Necker cube, p-value, phenotype, Ralph Waldo Emerson, Richard Feynman, Richard Feynman, Ronald Reagan, Solar eclipse in 1919, Steven Pinker, Zipf's Law

Napoleon didn't have to shoot off James Morris's arm in order to seal young Desmond's fate, and yours and mine, too. Not just Napoleon but the humblest medieval peasant had only to sneeze in order to affect something which changed something else which, after a long chain reaction, led to the consequence that one of your would-be ancestors failed to be your ancestor and became somebody else's instead. I'm not talking about 'chaos theory', or the equally trendy 'complexity theory', but just about the ordinary statistics of causation. The thread of historical events by which our existence hangs is wincingly tenuous. When compared with the stretch of time unknown to us, O king, the present life of men on earth is like the flight of a single sparrow through the hall where, in winter, you sit with your captains and ministers. Entering at one door and leaving by another, while it is inside it is untouched by the wintry storm; but this brief interval of calm is over in a moment, and it returns to the winter whence it came, vanishing from your sight.

None of the three assists our understanding of any of the others. The author is drunk on metaphor, captivated by the idea of the helix, which misleads him into seeing connections which do not illuminate the truth in any way. Calling it poetic science is too kind: it is more like theological science. Recently my incoming mail has registered a sharp rise in the normal load of 'chaos theory', 'complexity theory', 'non-linear criticality' and similar phrases. Now I'm not saying that these correspondents lack the faintest, foggiest clue what they are talking about. But I will say it's hard to discover whether they do. New Age cults of all kinds cure swimming in bogus scientific language, regurgitated, half-understood (no, less than half) jargon: energy fields, vibration, chaos theory, catastrophe theory, quantum consciousness.

Classical management theory: the notion that ‘mainstreaming’ a change within an organisation requires a systematic plan to make it happen. The vision for change must be shared amongst a critical mass of staff, and must be accompanied by planned changes to the visible structures of the organisation, to the roles and responsibilities of key individuals, and to information and communication systems. 6. Complexity theory: the notion that large organisations (such as the UK National Health Service) depend critically on the dynamic, evolving, and local relationships and communication systems between individuals. Supporting key interpersonal relationships, and improving the quality and timeliness of information available locally are often more crucial factors in achieving sustained change than ‘top-down’ directives or overarching national or regional programmes.

The point of Millennium Challenge was to show that, with the full benefit of high-powered satellites and sensors and supercomputers, that fog could be lifted. This is why, in many ways, the choice of Paul Van Riper to head the opposing Red Team was so inspired, because if Van Riper stood for anything, it was the antithesis of that position. Van Riper didn’t believe you could lift the fog of war. His library on the second floor of his house in Virginia is lined with rows upon rows of works on complexity theory and military strategy. From his own experiences in Vietnam and his reading of the German military theorist Carl von Clausewitz, Van Riper became convinced that war was inherently unpredictable and messy and nonlinear. In the 1980s, Van Riper would often take part in training exercises, and, according to military doctrine, he would be required to perform versions of the kind of analytical, systematic decision making that JFCOM was testing in Millennium Challenge.

Do you find it plausible that we, like car salesmen who unconsciously discriminate against certain groups of potential customers, or businesses that appear to favor tall men for CEOs, are not accountable for certain actions because they are a result of social influences rather than our personal beliefs? 16. Do you accept the argument that we are completely oblivious to our unconsciously motivated behavior (like the disturbing IAT results that show 80 percent of test takers have pro-white associations)? Is this just a convenient excuse to justify our biases? Chapter 4 / Paul Van Riper’s Big Victory 17. Van Riper believed that strategy and complex theory were inappropriate and futile in the midst of battle, “where the uncertainties of war and the pressures of time made it impossible to compare options carefully and calmly.” What other “work” situations discount rational analysis and demand immediate “battlefield” decision making? 18. Can one ever really prepare for decisive, rapid-fire scenarios? Is planning for the unpredictable worthwhile or a waste of time and energy?

Engineers learn a variety of skills during their training, first in university classes and then in on-the-job training working on real-world projects. Most important is to learn general principles. In engineering that includes the laws of physics and engineering principles of a particular discipline. In computing that would mean computer science principles such as algorithms, data structures, and complexity theory, as well as the principles of software engineering. In any field, it is important to develop a feel for how things are done. If software applications follow expected norms and are consistently designed, the skillful developer can often intuit the structure and behavior of a new system without searching piles of manuals. It’s also important to provide guidance on how a system works. It’s not enough to list the constituent parts and assume someone can figure out how it is all supposed to work when put together.

I want to draw a parallel to some of the things you’ve already said about your background in physics, where there are lots of layers. What’s applicable and appropriate in one layer is not necessarily appropriate at the other layer, but you also can’t deny the reality of the other layers. James: That’s the whole concept of emergent systems. That’s what science is all about and language is all about. That’s one of the concepts from the concept of complexity theory. You get the sense of emergence, and there’s no one fundamental layer. Certainly people have understood that in computing for a long time. You have multiple layers, and no one of them is the true layer. When you say the pattern movement has left itself very narrow on purpose, do you think it’s stuck at one layer when it should address the whole stack? James: Let me be fair to the pattern movement; there are people that worked at different layers.

If you spend a lot of time generalizing one area, you may find out that’s not the area where the changes need to be. It’s just like optimization. I really think too many programmers have worried about making things run fast in the wrong places. It’s been an obsession in this field for years and years. Even though computers have gotten so much faster, that doesn’t matter. They’re still obsessed with what I’ll call the micro-optimizations. They don’t know complexity theory, they don’t understand the “order-of” stuff, but they’re worried about little, itty-bitty speed improvements. I wrote a subroutine package and then I went and profiled it. You can’t always guess where you need to optimize, you’ve got to go measure, and then you fix those problems. One subroutine took 30% of the time. I fixed that subroutine. People overoptimize. It makes the program more likely to fail, and it may not be a place where it matters.

Number 2 is random because there is no scheme we can come up with apart from simply listing every element, one at a time, as it is in the actual sequence. Kolmogorov complexity theory encapsulates it this way: Something is random when you cannot explain how to derive a sequence using any fewer than the number of elements in the sequence itself. This definition of complexity meshes with our everyday, lay use of the term. We say that a car is more complex than a bicycle, and surely it takes a far larger set of instructions to build a car than a bicycle. Information theory can be applied to organizational systems like the file and folder hierarchy on your computer, or to org charts in a company. And, according to Kolmogorov complexity theory, if the org chart can be described by a small number of simple rules, the company is said to be highly structured.

Sustained concentration and effort is most effective not when fragmented into little pieces by multitasking, but when apportioned into big focused chunks separated by leisure, exercise, or other mentally restorative activities. Multitasking results from information overload, trying to attend to too many things at once. When the many things we’re attending to require a decision, how much information do we need to make optimal decisions? Optimal complexity theory states that there is an inverted U function for how much information or complexity is optimal. Too little is no good, but so is too much. In one study, experimenters simulated a military exercise. Players in the simulated game were college students in teams who were either invading or defending a small island country. Players were allowed to control the amounts of information with which to make their decisions—they received a document that read: The information you are receiving is prepared for you in the same way it would be prepared for real commanders by a staff of intelligence officers.

For instance, he shows, mathematically, that if we represent systems of relations by a graph, the key to generating a small-world phenomenon (which epitomizes a networking logic) is the presence of a small fraction of very long-range, global edges, which contract otherwise distant parts of the graph, while most edges remain local, organized in clusters.100 This accurately represents the logic of local/global networking of innovation, as documented in this chapter. The important contribution of the complexity theory school of thought is its emphasis on non-linear dynamics as the most fruitful approach to understanding the behavior of living systems, both in society and in nature. Most of the work of the Santa Fe Institute researchers is of a mathematical nature, not an empirically based analysis of natural or social phenomena. But there are researchers in a number of fields of science using non-linear dynamics as their guiding principle, with increasingly important scientific results.

Capra shows how cutting-edge research in areas as diverse as cell development, global ecological systems (as represented by the controversial Gaia theory, and by Lovelock’s “Daisyworld” simulation model), neuroscience (as in the work of Gerald Edelman or Oliver Sacks), and studies on the origins of life based on emerging chemical network theory, are all manifestations of a non-linear dynamics perspective.102 Key new concepts, such as attractors, phase portraits, emergent properties, fractals, offer new perspectives in making sense of observations of behavior in living systems, including social systems – thus paving the way for a theoretical linkage between various fields of science. Not by reducing them to a common set of rules, but by explaining processes and outcomes from the self-generating properties of specific living systems. Brian Arthur, a Stanford economist with the Santa Fe Institute, has applied complexity theory to formal economic theory, proposing concepts such as self-reinforcing mechanisms, path dependency, and emergent properties, and showing their relevance in understanding the features of the new economy.103 In sum, the information technology paradigm does not evolve toward its closure as a system, but toward its openness as a multi-edged network. It is powerful and imposing in its materiality, but adaptive and open-ended in its historical development.

Of course, sometimes the natural sciences themselves encountered something commensurable to a crisis in their own fields of endeavor—think of dark matter and dark energy, or the breakdown of causality in the 1920s—but they didn’t respond by evasive maneuvers and suppressing its consideration, as did the economists. In retrospect, appeals to science will be seen to have proven a bit of a red herring in coming to terms with the current crisis. Physical complexity theory or neuromysticism or dark matter won’t save us now. In the heat of battle, economists purported to be defending “science’”when, in fact, they were only defending themselves and their minions. Lesson 4: The failure of the economics profession is a saga of social disfunction The completeness of the [orthodox] victory is something of a curiosity and a mystery. It must have been due to a complex of suitabilities in the doctrine to the environment into which it was projected.

Evolutionary algorithms are adept at handling problems with too many variables to compute precise analytic solutions. The design of a jet engine, for example, involves more than one hundred variables and requires satisfying dozens of constraints. Evolutionary algorithms used by researchers at General Electric were able to come up with engine designs that met the constraints more precisely than conventional methods. Evolutionary algorithms, part of the field of chaos or complexity theory, are increasingly used to solve otherwise intractable business problems. General Motors applied an evolutionary algorithm to coordinate the painting of its cars, which reduced expensive color changeovers (in which a painting booth is put out of commission to change paint color) by 50 percent. Volvo uses them to plan the intricate schedules for manufacturing the Volvo 770 truck cab. Cemex, a $3 billion cement company, uses a similar approach to determining its complex delivery logistics.

A $1,000 personal computer (in 1999 dollars) can perform about a trillion calculations per second.4 Supercomputers match at least the hardware capacity of the human brain—20 million billion calculations per second.5 Unused computes on the Internet are being harvested, creating virtual parallel supercomputers with human brain hardware capacity. There is increasing interest in massively parallel neural nets, genetic algorithms, and other forms of “chaotic” or complexity theory computing, although most computer computations are still done using conventional sequential processing, albeit with some limited parallel processing. Research has been initiated on reverse engineering the human brain through both destructive scans of the brains of recently deceased persons as well as noninvasive scans using high resolution magnetic resonance imaging (MRI) of living persons.

According to general systems theory, conceptions of reduction are incorrect, at least at times. Instead, in general systems theory, a system is characterized by the interactions of its components and the nonlinearity of those interactions. In other words, we take the totality and the complexity of interactions into account simultaneously. Potpourri: General systems theory has a lot in common with chaos theory and complexity theory. Chaos theory addresses the study of complex dynamical systems (i.e., systems that follow a fixed rule over time), where the system is highly dependent on Bringing It All Together initial conditions. This means that very slight fluctuations in the initial conditions can radically affect the end state of the system. So, a ball balancing on a hilltop (using the classic example) may fall in many directions depending on very slightly changing atmospheric conditions.

Reflections on the motive force of life In chapter 2 we peered inside a steam engine to discover that its motive force involved capturing the random motion of the sea of billiard-ball-like molecules and directing the molecular turbulence toward driving the piston within the cylinder. We then asked whether life can be entirely accounted for by the same “order from disorder” thermodynamic principle that drives steam engines. Is life just an elaborate steam engine? Many scientists are convinced that it is, but in a subtle way that needs a little elaboration. Complexity theory studies the tendency of certain forms of random chaotic motion to generate order through the phenomenon of self-organization. For example, as we have already discussed, the molecules within liquids are moving entirely chaotically, yet when your bathtub is draining the water spontaneously flows around the drain in an orderly clockwise or counterclockwise direction. This macroscopic order can also be seen in the patterns of convection flow in a heated pot of water, in hurricanes, tornadoes, the red spot on Jupiter and many other natural phenomena.

Learn Python the Hard Way by Zed Shaw


complexity theory, finite state, index card, web application

This is the only time you are allowed to copy-paste. © Copyright 2010, Zed A. Shaw. Last updated on Jun 24, 2011. Exercise 27: Memorizing Logic Today is the day you start learning about logic. Up to this point you have done everything you possibly can reading and writing files, to the terminal, and have learned quite a lot of the math capabilities of Python. From now on, you will be learning logic. You won't learn complex theories that academics love to study, but just the simple basic logic that makes real programs work and that real programmers need every day. Learning logic has to come after you do some memorization. I want you to do this exercise for an entire week. Do not falter. Even if you are bored out of your mind, keep doing it. This exercise has a set of logic tables you must memorize to make it easier for you to do the later exercises.

The Search for Superstrings, Symmetry, and the Theory of Everything by John Gribbin


Albert Einstein, Arthur Eddington, complexity theory, dark matter, Dmitri Mendeleev, Ernest Rutherford, Fellow of the Royal Society, Isaac Newton, Murray Gell-Mann, Richard Feynman, Richard Feynman, Schrödinger's Cat, Stephen Hawking

—Kirkus Reviews “From the author of In Search of Schrödinger's Cat and In Search of the Big Bang comes yet another enthusiastic exploration on and lucid explanation of scientific theory.… Gribbin's straightforward approach leads the layman through the maze of scientific babble and ideas without either complicating or oversimplifying matters.” —Katrina Dixon, The Scotsman (U.K.) “Writing in his clear prose style, Gribbin introduces the general reader to the mysterious world of high-energy physics—a formidable task because of the complex theories involved; nevertheless, he translates these ideas into a readable, enjoyable narrative. His extensive historical treatment of physics research from the foundation work done in the 19th century to the latest concepts of superstrings is remarkable. Gribbin takes the reader to a world of multidimensions—a fictionlike picture—where scientists are trying to merge the forces of the universe in a grand unified theory called supersymmetry.”


The Life-Changing Magic of Tidying Up: The Japanese Art of Decluttering and Organizing by Marie Kondo


complexity theory, placebo effect

Let me share a secret. Putting your house in order is fun! The process of assessing how you feel about the things you own, identifying those that have fulfilled their purpose, expressing your gratitude, and bidding them farewell, is really about examining your inner self, a rite of passage to a new life. The yardstick by which you judge is your intuitive sense of attraction, and therefore there’s no need for complex theories or numerical data. All you need to do is follow the right order. So arm yourself with plenty of garbage bags and prepare to have fun. Start with clothes, then move on to books, papers, komono (miscellany), and finally things with sentimental value. If you reduce what you own in this order, your work will proceed with surprising ease. By starting with the easy things first and leaving the hardest for last, you can gradually hone your decision-making skills, so that by the end, it seems simple.

Clock of the Long Now by Stewart Brand


Albert Einstein, Brewster Kahle, Buckminster Fuller, Colonization of Mars, complexity theory, Danny Hillis, Eratosthenes, Extropian, fault tolerance, Internet Archive, Jaron Lanier, Kevin Kelly, knowledge economy, life extension, nuclear winter, pensions crisis, phenotype, Ray Kurzweil, Stephen Hawking, Stewart Brand, technological singularity, Ted Kaczynski, Thomas Malthus, Vernor Vinge, Whole Earth Catalog

Another version of the discounting debate emerges around long-term planning. Many have noticed, these decades, that there seem to be fewer long-duration projects, even though there is growing wealth to invest in such work. Kevin Kelly once raised the question at a dinner with complexity scientists. In friendly but acerbic terms they mocked the ambitions of The Long Now Foundation. Kelly paraphrased their argument: Since complexity theory shows that even the fairly near future is inherently unpredictable, any polygenerational plan will guess wrong about what a future generation wants or needs. Suppose a previous generation had expended great effort planning for dirigible ports around the world in the year 2000! Inevitable technology obsolescence and economic discounting renders any long-term return of value impractical. Conservation makes sense for the long term, and so does science (because it is incremental and open-ended), but specific long-term plans will always be based on wrong long-term predictions, and it is best to avoid them.

The amplification and adoption of useful innovation exist throughout natural history as well. Coral reefs are sometimes called the “cities of the sea,” and part of the argument of this book is that we need to take the metaphor seriously: the reef ecosystem is so innovative in its exploitation of those nutrient-poor waters because it shares some defining characteristics with actual cities. In the language of complexity theory, these patterns of innovation and creativity are fractal: they reappear in recognizable form as you zoom in and out, from molecule to neuron to pixel to sidewalk. Whether you’re looking at the original innovations of carbon-based life, or the explosion of new software tools on the Web, the same shapes keep turning up. When life gets creative, it has a tendency to gravitate toward certain recurring patterns, whether those patterns are emergent and self-organizing, or whether they are deliberately crafted by human agents.

The Planet on the Table by Kim Stanley Robinson


complexity theory, Murano, Venice glass

“But could such an addition to the data banks be made?” “It would be easiest done on Earth,” Freya said. “But there is no close security guarding the banks containing old art books. No one expects them to be tampered with.” “It’s astonishing,” I said with a wave of my fork, “it is baroque, it is byzantine in its ingenuity!” “Yes,” she said. “Beautiful, in a way.” “However,” I pointed out to her, “you have no proof— only this perhaps over-complex theory. You have found no first edition of a book to confirm that the computer-generated volumes add Heidi’s painting, and you have found no physical anachronism in the painting itself.” Gloomily she clicked her fork against her empty salad bowl, then rose to refill it. “It is a problem,” she admitted. “Also, I have been working on the assumption that Sandor Musgrave discovered evidence of the forgery.

These were almost impossible to find on the Continent, but anonymous reviews appeared in three young journals in the spring and summer of 1688, and the book’s reputation spread.13 When the Marquis de l’Hôpital wondered why no one knew what shape let an object pass through a fluid with the least resistance, the Scottish mathematician John Arbuthnot told him that this, too, was answered in Newton’s masterwork: “He cried out with admiration Good god what a fund of knowledge there is in that book?… Does he eat & drink & sleep? Is he like other men?”14 Its publication notwithstanding, he had never stopped working on the Principia. He was preparing a second edition. He scoured Greek texts for clues to his belief that the ancients had known about gravity and even the inverse-square law. He contemplated new experiments and sought new data for his complex theory of the moon’s motions. Besides correcting printer’s errors, he was drafting and redrafting whole new sections, refining his rules for philosophy. He struggled with the inescapable hole in his understanding of gravity’s true nature. He twisted and turned: “Tis inconceivable that inanimate brute matter should (without the mediation of something else which is not material) operate upon & affect other matter without mutual contact,” he wrote one correspondent.

But those are old theories and the real action and value-add comes from the data and its handling, including data from field experiments, laboratory experiments, and from randomized control trials. The underlying models just aren’t getting that much better, and when the underlying models are more complicated, they very often are not more persuasive to the typical research economist. I would sum up the blend as follows: (a) much better data, (b) higher standards for empirical tests, and (c) lots of growth in complex theory but not matched by a corresponding growth in impact. Mathematical economics, computational economics, complexity economics, and game theory continue to grow, as we would expect of a diverse and specialized discipline, but they are if anything losing relative ground in terms of influence. Economics is becoming less like Einstein or Euclid, and more like studying the digestive system of a starfish.

Execution: The Discipline of Getting Things Done by Larry Bossidy


Albert Einstein, business process, complexity theory, Iridium satellite, Long Term Capital Management, NetJets, shareholder value, six sigma, social software, Socratic dialogue, supply-chain management

To change a business’s culture, you need a set of processes—social operating mechanisms—that will change the beliefs and behavior of people in ways that are directly linked to bottom-line results. In this chapter, we present a new reality-based framework for cultural change that creates and reinforces a discipline of execution. This approach is practical and completely linked to measurable business results. The basic premise is simple: cultural change gets real when your aim is execution. You don’t need a lot of complex theory or employee surveys to use this framework. You need to change people’s behavior so that they produce results. First you tell people clearly what results you’re looking for. Then you discuss how to get those results, as a key element of the coaching process. Then you reward people for producing the results. If they come up short, you provide additional coaching, withdraw rewards, give them other jobs, or let them go.

Several of her former PhD students stand out as essential contributors to the simple rules ideas. Kathy’s simple rules journey began when she and Shona Brown began studying the strategies of technology-based companies as Shona worked on her dissertation. They were searching for fresh ideas that would break away from the stale paradigms of traditional strategy and organization theory. They found those ideas at the “edge of chaos” in complexity theory, and penned Competing on the Edge: Strategy as Structured Chaos. This project became a precursor to the simple rules research. Kathy is also indebted to another former PhD student, Professor Chris Bingham of the University of North Carolina. Chris was the perfect research partner, and together they pushed forward insights into how simple rules are learned and why they work so well. Nathan Furr, now a professor at Brigham Young University, pitched in with a thoughtful analysis showing the power of learning simple rules over simply accumulating experience.

There is also a fascinating and possibly even more important flip side of chaos: that the repeated application of the same simple rules which lead to chaotic behavior, starting from organized regular motion, can sometimes lead from bland, structureless form to the emergence of beautiful and complex patterns—that we can get order and complexity where there was none before. You start with something without structure, allow it to evolve, and you begin to see structure and patterns spontaneously emerging. This idea has led to the spawning of new academic disciplines known as emergence and complexity theory, which are beginning to play a major role in many diverse areas, from biology to economics to artificial intelligence. FREE WILL When it comes to what all this has to say about the nature of free will (and therefore about the Paradox of Laplace’s Demon), there are still many different philosophical views and the issue is far from resolved. All I can do is give you my opinion as a theoretical physicist.

So the representation of (49) is the following, with the original unpronounced occurrences within angled brackets: (51) a. Which picture of himself does John prefer <which picture of himself> b. Which picture of John does he prefer <which picture of John> The binding principles apply on these richer representations giving the right result: the anaphor is bound by the name in (51a), the name cannot enter into a coreference relation with the c-commanding pronoun in (51b). No complex theory of reconstruction is needed, and the empirically correct result is achieved by simply tracing “movement” back to its elementary computational components (on the adjustments needed to get appropriate operator-variable structures at LF see Chomsky (1993), Fox (2000), Rizzi (2001b); on the fact that it is 43 On nature and language apparently sufficient to bind only one occurrence of the anaphor in (51a) see the references just quoted, and also the discussion in Belletti and Rizzi (1988); on the different behavior of arguments and adjuncts under reconstruction, Lebeaux (1988)).

It would be some two centuries later, with the development of computers with massive computational prowess, until equations that would have taken a stadium full of people working for hundreds of years to solve could be solved in a matter of seconds. Relatively precise solutions to the three-body problem were demonstrated. A new field known by various names, including nonlinear dynamics, fractals, chaos, or complexity theory, began to emerge. The concept of the butterfly effect, whereby a flutter of a butterfly wing might cause a massive change in the weather countries away, became common knowledge. In short, it was now understood that everything affects everything else in multifaceted, often unpredictable ways. The critical middle, the stuff in between, as it were, is the infinite complexity of systems that are totally interactive, interconnected, and interdependent.

That is the sin of greedy reductionism, but notice that it is only when overzealousness leads to falsification of the phenomena that we should condemn it. In itself, the desire to reduce, to unite, to explain it all in one big overarching theory, is no more to be condemned as immoral than the contrary urge that drove Baldwin to his discovery. It is not wrong to yearn for simple theories, or to yearn for phenomena that no simple (or complex!) theory could ever explain; what is wrong is zealous misrepresentation, in either direction. Darwin's dangerous idea is reductionism incarnate,9 promising to unite and explain just about everything in one magnificent vision. Its being the idea of an algorithmic process makes it all the more powerful, since the substrate neutrality it thereby possesses permits us to consider its application to just about anything.

Kauffman's new book, The Origins of Order: Self-Organization and Selection in Evolution (1993), summarizes and extends the research he has been engaged in for several decades, and lets us see for the first time how he himself places his ideas in the context of the history of the field. Many have heralded him as a Darwin-slayer, finally driving that oppressive presence from the scene, and doing it, moreover, with the flashing blade of {221} brand-new science: chaos theory and complexity theory, strange attractors and fractals. He himself has been tempted by that view in the past (Lewin 1992, pp. 40-43), but his book bristles with warnings, fending off the embrace of the anti-Darwinians. He begins the preface of his book (p. vii) by describing it as "an attempt to include Darwinism in a broader context": Yet our task is not only to explore the sources of order which may lie available to evolution.

Deterrence theory was the underpinning of U.S., Soviet, and NATO nuclear strategy during the Cold War. The horror that could be caused by nuclear weapons (and the fear that any use would lead to extensive use) deterred nuclear-weapons nations from using their ultimate weapons against each other. It also deterred nations, both nuclear-armed and not, from doing anything that might provoke a nuclear response. Strategists developed complex theories about nuclear deterrence. Herman Kahn developed a typology with three distinct classes of nuclear deterrence in his works in the 1960s. His theories and analyses were widely studied by civilian and military leaders in both the United States and the Soviet Union. His clear, matter-of-fact writing about the likely scope of destruction in books like On Thermonuclear War (1960) and Thinking About the Unthinkable (1962) undoubtedly helped to deter nuclear war.

Dawes (1999), in fact, makes the stronger argument that human “cognitive capacity shuts down in the absence of a story.” 16. For example, a preference for simplicity in explanations is deeply embedded in the philosophy of science. The famous Ockham’s razor—named for the fourteenth-century English logician William of Ockham—posits that “plurality ought never be posited without necessity,” meaning essentially that a complex theory ought never to be adopted where a simpler one would suffice. Most working scientists regard Ockham’s razor with something close to reverence—Albert Einstein, for example, once claimed that a theory “ought to be as simple as possible, and no simpler”—and the history of science would seem to justify this reverence, filled as it is with examples of complex and unwieldy ideas being swept away by simpler, more elegant formulations.

In these three- to four-day programs for adults and seven- to eight-day programs for teens, stargazers find themselves observing, photographing, and electronically imaging various celestial objects through professional-grade telescopes, devising theories on globular clusters, and identifying near-Earth asteroids that only astronomy professors usually know about. The enthusiastic teacher, Don McCarthy, the University of Arizona professor who heads the programs, is so much fun (he has a whole collection of music about stars—for example, from Annie, Phantom of the Opera, and Cats) and has such a knack for explaining complex theories that past campers keep coming back year after year. In fact, Lisa Roubal, codirector of the program, jokes that she practically has to beg Astronomy Camp alumni to wait a year before returning so there will be room for new campers. Astronomy Camp, which has been going strong since 1988, takes place at Mount Lemmon, a mountaintop observatory just north of Tucson. Although the bulk of the programs are geared for teenagers, the adult programs are scheduled around the phases of the moon and are held several times a year in the spring through fall.

Why should someone have a good memory for sounds and words but not for other things? In music, he was average; tests of visuospatial ability stumped him; he said he couldn’t read maps or figure out new routes. This intrigued her, since it’s often thought that exceptional verbal abilities are associated with limited visuospatial abilities, or vice versa. To give these overlaps some order, she looked to a complex theory known as the Geschwind-Galaburda hypothesis, which links co-occurrences among dyslexia, gender, handedness, and other traits. As examples, there’s a predominance of left-handers among talented visual artists, and males are overwhelmingly more often dyslexic and autistic. In the 1980s, neurologists Norman Geschwind and Albert Galaburda looked to brain development for an answer. They observed that the left hemispheres of the brains of fetal rats developed more slowly if testosterone spiked at certain developmental moments.

If the NSF is going to significantly increase its support for interdisciplinary decision sciences, risk management, and disaster research, integrated social/ economic/ecological/geo-science data are needed. Suppose we had these data? What do we do then? How do we aggregate? Traditional probabilistic risk assessment has obvious limitations for understanding extreme events, but what are the alternatives? Are new approaches such as complexity theory part of the answer? What can we learn from these data that will help us better understand individual and collective behaviors in the face of catastrophes? The NSF itself will not answer these questions, but it is likely to fund leading scholars who will. Their work, informed by both disciplinary and interdisciplinary learning, will ultimately change the way many people think of the world and affect their daily decisions.

Turns out he’s the doc’s son. Clone. I ’spect you knew that, though.” “Sam? Brick shithouse Sam?” There’s a distant, roaring sob and another crash. “Who’d have thought he had it in him?” “Whose side are you on, Ade? What have you been selling these bastards? I expect I’ll be dead by dusk, so you can tell me.” “I told you, but you didn’t listen. There is no conspiracy. The movement is an emergent phenomenon. It’s complexity theory, not ideology. The cloud wants to instantiate an ambassador, and events conspire to find a suitable host and get some godvomit down his throat.” Ade nods at him. “Now the cloud wants the ambassador to commune with something on the American continent, and there you are. How do I know the cloud wants this? Because you are there, on the American continent. QED. Maybe it wants to buy Manhattan for some beads.

The Future of the Brain: Essays by the World's Leading Neuroscientists by Gary Marcus, Jeremy Freeman

The action of the circuit as a whole is fully determined by the sum total of these specific interactions. A corollary is that circuit function is fully decomposable (given complete data) into neat sequences of causes and effects. In this sense, circuits resemble Laplacian models of classical mechanics, with circuit elements exerting purely local effects on each other and with connections mediating specific causal roles. In contrast, modern approaches from complexity theory and network science emphasize that global outcomes are irreducible to simple localized causes, and that the functioning of the network as a whole transcends the functioning of each of its individual elements. One key concept is that of “emergence.” Emergence builds on the basic observation that collective interactions among the elements of complex networked systems often give rise to new properties that do not exist at lower levels of organization.

For seconds, blame Trofim Lysenko for corrupting their science faculty's ability to cope with new findings that contradicted received political doctrine. For thirds, blame the Politburo, which, in the 1950s, looked at the embryonic IT industry, thought "tools of capitalist profit-mongers," and denounced computer science as un-Communist. Proximate results: they got into orbit using hand calculators, but completely dropped the ball on anything that required complexity theory, automated theorem proving, or sacrificial goats. But that was then, and this is now, and we're not dealing with the Union of Soviet Socialist Republics, we're dickering with the Russian Federation. (When we're not trying to save ourselves from the end of the world, that is.) The Russians are no longer dragged backwards by the invisible hand of Lenin. Their populace have taken with gusto to god-bothering and hacking, their official government ideology is "hail to the chief," and Moscow is the number one place on the planet to go if you want to rent a botnet.

In 1795 he managed to secure work as a clerk in a cloth-making concern and, a few years later, as a traveling salesman. In 1826 he finally settled in Paris. Fourier’s first book appeared in 1808; his second not until 1822. These as well as his subsequent works received little attention, thanks to his terrible writing style. Only late in life did he gain a following, but he remained a reclusive bachelor whose complex theories of passionate attraction were cosmically distant from his personal practices.25 Fourier persistently preached that his version of utopia could come about only in small communities whose inhabitants actually knew one another, not in big cities filled with anonymous masses. He asserted the economic and moral superiority of agriculture over manufacturing. Yet Fourier recognized that communal living in itself was no panacea.

One truly influential idea in physics is the famous principle known as Occam’s Razor, attributed to William of Ockham, a fourteenth-century English logician. On the most basic level, it says that if there are competing explanations for why something occurs the way it does, you should pick the one that relies on the fewest assumptions and is thus the simplest. When Renaissance astronomers were trying to explain the movement of the planets, for example, there were many complex theories. The prevailing belief was that orbits were perfect circles, or epicycles, but as planetary observation improved, the models based on circles had to be made extremely complex in order to work. Then, Johannes Kepler hit upon the comparatively simple idea that the orbit of every planet is an ellipse, with the sun at one of two foci within it. The explanation’s simplicity seemed proof that it was the right one—and with that simplicity came great power.

“Newton’s geometry seems to shriek and groan under the strain, but it works perfectly.” There are almost no other historical examples of so strange a performance as this use/nonuse of calculus. To get something of its flavor, we have to imagine far-fetched scenarios. Think, for instance, of a genius who grew up using Roman numerals but then invented Arabic numerals. And then imagine that he conceived an incredibly complex theory that relied heavily on the special properties of Arabic numerals—the way they make calculations easy, for instance. Finally, imagine that when he presented that theory to the world he used no Arabic numerals at all, but only Roman numerals manipulated in obscure and never-explained ways. Decades after the Principia, Newton offered an explanation. In his own investigations, he said, he had used calculus.

Governments should seek to use competitive private enterprise to deliver public utilities and services wherever possible. Getting the public finances into balance should be the overwhelming priority of fiscal policy. Taxation is necessary; but because it tends to disincentivise wealth creation and work, it should be kept as low as possible. Within each of these propositions lurks many a disagreement among academic economists, often informed by subtly complex theory and detailed empirical evidence. But it is not hard to find these views expressed in public debate; and they have dominated the practice of policy-making over recent years. The orthodox model provides an attractively simple framework for thinking about economics and policy. It combines the mathematical elegance of neoclassical microeconomics with plausible claims about the macroeconomy. The fact that many of the policy prescriptions which follow from it favour those in positions of incumbent economic power has given it a powerful grip on public discourse.

Still, it wasn’t obvious how to weave what amounted to a collection of insights about an emotion into a theory of how people make risky decisions. They were groping. Amos liked to use an expression he’d read someplace: “carving nature at its joint.” They were trying to carve human nature at its joint, but the joints of an emotion were elusive. That was one reason Amos didn’t particularly like to think or talk about emotion; he didn’t like things that were hard to measure. “This is indeed a complex theory,” Danny confessed one day in a memo. “In fact it consists of several mini-theories, which are rather loosely connected.” In reading about expected utility theory, Danny had found the paradox that purported to contradict it not terribly puzzling. What puzzled Danny was what the theory had left out. “The smartest people in the world are measuring utility,” he recalled. “As I’m reading about it, something strikes me as really, really peculiar.”

'Show me the Chairman of the Board of the forest, show me the chief financial fish in the pond, show me' (tapping his head) 'the Chief Executive neuron of the brain.' It is indeed true that all this is not applicable just to monetary or business matters. The work pioneered by the Santa Fe Institute on complex adaptive systems has verified these principles in all types of systems physical, biological, social, economic, etc.) which are reaching a certain level of complexity. Complexity theory predicts that contrary to Newtonian logic, complexity does not grow linearly, but occurs in non-linear jumps in episodic stages of 'surfing at the edge of chaos'. These 'near-chaos' periods are when systems regenerate and restructure at the next level of complexity, according to Nobel Prize-winners Ilya Prigogine. I believe we have now started to 'surf at the edge of chaos', that the current crisis of the dominant institutions of modern society is the sign that humanity has started to reorganise at the next level of complexity (see sidebar on the butterfly metaphor).

The End of College: Creating the Future of Learning and the University of Everywhere by Kevin Carey


Albert Einstein, barriers to entry, Berlin Wall, business intelligence, carbon-based life, Claude Shannon: information theory, complexity theory, declining real wages, deliberate practice, discrete time, double helix, Douglas Engelbart, Downton Abbey, Drosophila, Firefox, Frank Gehry, Google X / Alphabet X, informal economy, invention of the printing press, inventory management, Khan Academy, Kickstarter, low skilled workers, Lyft, Mark Zuckerberg, meta analysis, meta-analysis, natural language processing, Network effects, open borders, pattern recognition, Peter Thiel, pez dispenser, ride hailing / ride sharing, Ronald Reagan, Sand Hill Road, self-driving car, Silicon Valley, Silicon Valley startup, social web, South of Market, San Francisco, speech recognition, Steve Jobs, technoutopianism, transcontinental railway, Vannevar Bush

He and two coauthors recently name-checked a well-known article called “The Unreasonable Effectiveness of Mathematics in the Natural Sciences,” which “examines why so much of physics can be neatly explained with simple mathematical formulas such as F = ma or E = mc2. Meanwhile, sciences that involve human beings rather than elementary particles have proven more resistant to elegant mathematics.” “Perhaps when it comes to natural language processing and related fields,” they wrote, “we’re doomed to complex theories that will never have the elegance of physics equations. But if that’s so, we should stop acting as if our goal is to author extremely elegant theories, and instead embrace complexity and make use of the best ally we have: the unreasonable effectiveness of data.” Learning and human cognition are definitely among the “related fields.” Theorists like Vygotsky, Piaget, and their intellectual descendants have improved our understanding of learning in many important ways.

We saw those arrows radiating out from the initial information state, the cosmic singularity, engendering all manner of organizations (figure 2.2). We picked among the arrows—and it was out of sheer self-interest—the one bearing for our little perch in the universe. But all the others are made of the same gossamery stuff. And gossamery is the right word. No matter how physicists and information theorists dealt with it, whether by using Boltzmann’s statistical mechanics, Shannon’s equation, complexity theory, or Planck’s energy-frequency relationship, and no matter how exact the quantifications, it always was, and could not escape being, something ethereal. Well, no longer. The astonishing experiments with quantum-computing molecules dealt with in the preceding chapter give us an almost palpable experience. What is more, they give us a new perspective on the molecular world, where molecules engage in internal quantum information processing and computing as much as in exchanging with each other macroscopic chunks of information.

Geography, unlike its public image, is an entertaining as well as enlightening field, but what follows is also serious—dead serious. READING MAPS AND FACING THREATS It is often said that a picture is worth a thousand words. If that is true, then a map is worth a million, and maybe more. Even at just a glance, a map can reveal what no amount of description can. Maps are the language of geography, often the most direct and effective way to convey grand ideas or complex theories. The mother of all maps is the globe, and no household, especially one with school-age children, should be without one. A globe reminds us of the limits of our terrestrial living space when about 70 percent of its surface is water or ice, and much of the land is mapped as mountains or desert. A globe shows us that the shortest distance between the coterminous United States and China is not across the Pacific Ocean but over Alaska and the Bering Sea.

I'd advise people to consider it for its entertainment value."" IS THAT SO? "Eat Right For Your Type is the diet solution to staying healthy, living longer, and achieving your ideal weight." -Peter D'Adamo86 "Eat Right For Your Type is not only one of the most preposterous books on the market, but also one of the most frightening. It contains just enough scientificsounding nonsense, carefully woven into a complex theory, to actually seem convincing to the uninitiated. Based on his and his father's 'research' and observation of patients, D'Adamo has pieced together the outrageous hypothesis that blood type determines which foods an individual should or should not eat.... Browsing through what at first glance appears to be a fairly impressive list of references, we found none that seem to support a connection between diet and blood type....

THE MATH DEPARTMENT at Bell Laboratories had grown up around a single man, Thornton Fry, the son of a poor Ohio carpenter who was working on a PhD at the University of Wisconsin when Harold Arnold came through town on a recruiting trip in 1916. It was still a few years before the creation of Bell Labs, and Arnold, Western Electric’s research chief, was looking for a young mathematician who could assist the engineers with the complex theory that often accompanied their switching and transmission plans. In a job interview, Arnold asked Fry a number of questions to test his knowledge about the era’s most influential communications engineers. Did the young man know the work of Heaviside, Campbell, or Molina?17 Fry shook his head. He didn’t know a single one. Arnold must have nonetheless seen something encouraging in Fry. He gave him a job offer—$36 a week—and Fry immediately accepted.

The unsustainable inflation in value was incomprehensible to the few that believed in rationality and efficiency. Trend chasers, ‘mo’ (momentum) buyers, kept buying because they kept making money; nobody could explain the overvaluation; the doomsayer’s position became untenable and, puzzled by the duration of overvaluation, even intelligent and honest analysts eventually succumbed, evolving complex theories of why it was different this time. The overvaluation was sustainable after all. Theories of the ‘new economy’ and the good returns allowed suspension of reality for a little longer but eventually, the Ponzi scheme collapsed.3 Every rising market is driven by a new paradigm, every crash is the same as the last crash. In 2001, the Internet bubble burst. The NASDAQ index fell 80%. Eliot Spitzer and the SEC (Securities and Exchange Commission) belatedly took up the issue of the analysts and some were banned from the securities industry.

The smartest person is not always the most successful; the wisest policies are not always those adopted. Recently I spent an hour reading about the Middle East situation, and thinking. I didn’t come up with a solution. Now imagine a hypothetical Speedup SuperIntelligence Machine (as described by Nick Bostrom) that can think as well as the smartest human but 1,000 times faster. I doubt if it would come up with a solution either. Computational complexity theory reveals a wide class of problems immune to intelligence, in the sense that no matter how clever you are, no approach is any better than trying all possible solutions; no matter how much computing power you have, it won’t be enough. There are of course many problems where computing power does help. If I want to simulate the movements of billions of stars in a galaxy or compete in high-frequency stock trading, I’ll appreciate the help of a computer.

The Teeth of the Tiger by Tom Clancy

The Marines were now investing considerable time, money, and effort in learning city fighting, and the hardest part of it was avoiding civilians, women with kids in strollers-even knowing that some of those women had weapons stashed next to little Johnny, and that they'd love to see the back of a United States Marine, say two or three meters away, just to be sure of bullet placement. Playing by the rules had its limitations. But for Brian that was a thing of the past. No, he and his brother were playing the game by the enemy's rules, and as long as the enemy didn't know it would be a profitable game. How many lives might they have saved already by taking down a banker, a recruiter, and a courier? The problem was that you could never know. That was complexity theory as applied to real life, and it was a priori impossible. Nor would they ever know what good they'd be doing and what lives they might be saving when they got this 56MoHa bastard. But not being able to quantify it didn't mean it wasn't real, like that child killer his brother had dispatched in Alabama. They were doing the Lord's work, even if the Lord was not an accountant. At work in the field of the Lord, Brian thought.

But as profits and stock indexes rose, the stars themselves seemed to be aligning, and systems theory was as good a way as any of justifying the same options packages that young programmers would have been embarrassed by just a few years before, when they were antiestablishment hackers. While computer programmers were finding jobs in Silicon Valley, social scientists and chaos mathematicians won contracts at corporate-funded think tanks. The Santa Fe Institute studied complexity theory, and applied its findings to the market. The “four Cs,” as they came to be known—complexity, chaos, catastrophe, and cybernetics—now dominated economic thought. Building on the work of Hayek, the new science of economics held that there was no global, central controller in an economy—only a rich interaction between competing agents. Order, such as it was, emerged naturally and spontaneously from the system—the same way life evolved from atoms or organization emerges from an anthill.

What Happened to Goldman Sachs: An Insider's Story of Organizational Drift and Its Unintended Consequences by Steven G. Mandis

As Harvard Business School professor Scott Snook argues, detecting organizational drift requires a sensitivity to the passage of time; single snapshots won’t do.1 To understand what’s happened to Goldman since the writing of the business principles in 1979, then, we have to look back to its performance over time, how its interpretation of the principles has changed, and the conditions in which it operates. But before we get to that analysis, it’s worth developing a deeper understanding of organizational drift and its implications. Drift into Failure Sidney Dekker, a professor who specializes in understanding human error and safety, has used complexity theory and systems thinking to better understand how complex systems “drift into failure” over an extended period of time. His theories are worth exploring because they, and the ideas of other researchers, provide us with a clear understanding of how systems interact and drift away from intended goals. In some cases, this can end in disaster. In the case of Goldman, it means that there’s a distinct gap between the principles by which the firm purports to steer itself and what it’s actually doing in the world.

MacDonald invited him to lunch three times between November and December 1929 to ask for advice, and appointed Keynes to his Economic Advisory Council. But it soon dawned on Keynes that the timorous MacDonald, for all his radical credentials, was no progressive and in many respects was far less “socialist” than he was. Keynes provided the Macmillan Committee with a bravura performance at which he expostulated at length, and with extraordinary eloquence, his complex theories in language the layman could understand. The chairman, Lord Macmillan, a passionless judge, was so enamored with Keynes’s hypnotic daily lectures that he told him, “We hardly notice the lapse of time when you are speaking.”43 For those who find the ideas in A Treatise hard to grasp, Keynes’s exposition of them in plain language makes for hugely enjoyable reading, not least when he explains the effects of a disparity between savings and investment by invoking the workings of an imaginary banana republic.44 Along with the principles established in A Treatise, Keynes described his views on a number of elements in the economy that would become important in advancing the Keynesian Revolution and would define the difference between his ideas and those of the Austrian School in the impending duel with Hayek.

Studying the behaviour of complex phenomena assumes the existence of a mysterious, hitherto undetected ‘force’ that lies beyond the constituent parts of the system. The emergentists’ counterargument is that interactions between the constituent parts of the system are also important for the behaviour of the system as a whole. However, if interactions are so important, what is the nature of these interactions? And how can we test whether they exist or not? For many scientists, emergentist theories that spring from cybernetics and complexity theory do not seem falsifiable, and are therefore suspiciously non-scientific. Suspicion about theories of emergence reflects the ideological divide between traditional scientific methods of reductionism versus alternative systemic, or holistic, methods. Reductionism is the very successfully applied idea in science whereby one tries to reduce a natural phenomenon to an irreducible level that can be then studied.

Part of the reason, he suspects, is just their “failure to communicate what they can add to philosophy’s conceptual arsenal.” He elaborates: One might think that, once we know something is computable, whether it takes 10 seconds or 20 seconds to compute is obviously the concern of engineers rather than philosophers. But that conclusion would not be so obvious, if the question were one of 10 seconds versus 101010 seconds! And indeed, in complexity theory, the quantitative gaps we care about are usually so vast that one has to consider them qualitative gaps as well. Think, for example, of the difference between reading a 400-page book and reading every possible such book, or between writing down a thousand-digit number and counting to that number. Computer science gives us a way to articulate the complexity of evaluating all possible social provisions for something like an injured shin.

Because Bernoulli’s model lacks the idea of a reference point, expected utility theory does not represent the obvious fact that the outcome that is good for Anthony is bad for Betty. His model could explain Anthony’s risk aversion, but it cannot explain Betty’s risk-seeking preference for the gamble, a behavior that is often observed in entrepreneurs and in generals when all their options are bad. All this is rather obvious, isn’t it? One could easily imagine Bernoulli himself constructing similar examples and developing a more complex theory to accommodate them; for some reason, he did not. One could also imagine colleagues of his time disagreeing with him, or later scholars objecting as they read his essay; for some reason, they did not either. The mystery is how a conception of the utility of outcomes that is vulnerable to such obvious counterexamples survived for so long. I can explain it only by a weakness of the scholarly mind that I have often observed in myself.

It is not a trivial consideration. We are capable of walking on all fours like a typical mammal, but it is uncomfortable: hard work, because of our altered body proportions. Those proportional changes which now make us feel comfortable on two legs originally came about, Kingdon suggests, in the service of a minor shift in food habits -- to squat feeding. There is much more in Jonathan Kingdon's subtle and complex theory, but I will now recommend his book, Lowly Origin, and move on. My own slightly way-out theory of bipedality is very different but not incompatible with his. Indeed, most of the theories of human bipedality are mutually compatible, with the potential to assist rather than oppose one another. As in the case of the enlargement of the human brain, my tentative suggestion is that bipedality may have evolved through sexual selection, so again I postpone the matter to the Peacock's Tale.

These types of systems have emergent properties that simply cannot be predicted. We all know this! Yet proponents of geoengineering research leave that out of the discussion.”22 Indeed in my time spent among the would-be geoengineers, I have been repeatedly struck by how the hard-won lessons about humility before nature that have reshaped modern science, particularly the fields of chaos and complexity theory, do not appear to have penetrated this particular bubble. On the contrary, the Geoclique is crammed with overconfident men prone to complimenting each other on their fearsome brainpower. At one end you have Bill Gates, the movement’s sugar daddy, who once remarked that it was difficult for him to decide which was more important, his work on computer software or inoculations, because they both rank “right up there with the printing press and fire.”

City: Urbanism and Its End by Douglas W. Rae


agricultural Revolution, barriers to entry, business climate, City Beautiful movement, complexity theory, desegregation, edge city, ghettoisation, income per capita, informal economy, interchangeable parts, invisible hand, James Watt: steam engine, Jane Jacobs, joint-stock company, Joseph Schumpeter, manufacturing employment, New Economic Geography, new economy, New Urbanism, Plutocrats, plutocrats, Saturday Night Live, the built environment, The Death and Life of Great American Cities, the market place, urban planning, urban renewal, War on Poverty, white flight, Works Progress Administration

Contact with strangers, handled with responses that allow civil cooperation well short of personal intimacy, is at the heart of Jane Jacobs’ justly celebrated work on urbanism. See Jacobs, The Death and Life of Great American Cities (New York: Random House, 1961). See also Lyn H. Lofland, A World of Strangers (New York: Basic Books, 1973). For a more developed theoretical treatment of contact with diversity, see Richard Sennett, The Uses of Disorder (New York: Norton, 1970). Gerald Frug has constructed an inspiring and complex theory of urban change that hinges to a considerable degree on overcoming the sorting processes of late twentieth-century urban regions. See Frug, City Making: Building Cities Without Building Walls (Princeton: Princeton University Press, 1999). 46. By way of counterpoint, the explicit idea of urbanism was quite commonly used in a positive, normative vein. Thus, in 1934, Columbia University established an Institute of Urbanism.

Write Great Code, Volume 2 by Randall Hyde


complexity theory, locality of reference, NP-complete, premature optimization

For this reason, the optimization process is usually a case of compromise management, where you make tradeoffs and sacrifice certain subgoals (for example, running certain sections of the code a little slower) in order to create a reasonable result (for example, creating a program that doesn’t consume too much memory). Optimization’s Effect on Compile Time You might think that it’s possible to choose a single goal (for example, highest possible performance) and optimize strictly for that. However, the compiler must also be capable of producing an executable result in a reasonable amount of time. The optimization process is an example of what complexity theory calls an NP-complete problem. These are problems that are, as far as we know, intractable. That is, a guaranteed correct result cannot be produced (for example, an optimal version of a program) without computing all possibilities and choosing the best result from those possibilities. Unfortunately, the time generally required to solve an NP-complete problem increases exponentially with the size of the input, which in the case of compiler optimization means roughly the number of lines of source code.

They all learned eventually that intelligence agencies pay poorly (except for CIA, which rewarded treason with real money), but by then it was always too late to turn back. From Walker the Russians had learned how American cipher machines were designed and how their keying systems worked. The basics of the cipher machines hadn't really changed all that much in the preceding ten years. Improved technology had made them more efficient and much more reliable than their stepping-switch and pin-disc ancestors, but they all worked on a mathematical area called Complexity Theory, which had been developed by telephone engineers sixty years earlier to predict the working of large switching systems. And the Russians had some of the best mathematical theorists in the world. It was believed by many that knowledge of the structure of cipher machines might enable a really clever mathematician to crack a whole system. Had some unknown Russian made a theoretical breakthrough?

Had he known that fact earlier in the day, he might have sought permission to give in on the point, but he hadn't and he didn't. To change now would be an admission of error, and Nagumo didn't like to do that any more than anyone else in the world. He decided that he'd suggest an improved offer for licensing rights, instead—not knowing that by failing to accept a personal loss of face, he'd bring closer something that he would have tried anything to avoid. 5—Complexity Theory Things rarely happen for a single reason. Even the cleverest and most skillful manipulators recognize that their real art lies in making use of that which they cannot predict. For Raizo Yamata the knowledge was usually a comfort. He usually knew what to do when the unexpected took place—but not always. "It has been a troublesome time, that is true, but not the worst we have experienced," one of his guests pronounced.
