(Photograph courtesy of Wolfram Research, Inc.) Whew. With all that fame, funding, and the freedom to do whatever he wanted, Wolfram chose to study the dynamics of cellular automata. In the spirit of good theoretical physics, Wolfram set out to study the behavior of cellular automata in the simplest form possible—using one-dimensional, two-state cellular automata in which each cell is connected only to its two nearest neighbors (figure 10.4a). Wolfram termed these “elementary cellular automata.” He figured that if he couldn’t understand what was going on in these seemingly ultra-simple systems, there was no chance of understanding more complex (e.g., two-dimensional or multistate) cellular automata. Figure 10.4 illustrates one particular elementary cellular automaton rule. Figure 10.4a shows the lattice—now just a line of cells, each connected to its nearest neighbor on either side.

A cellular automaton rule—also called a cell update rule—is simply the identical rule followed by each cell, which tells the cell what its state should be at the next time step as a function of the current states in its local neighborhood. Why do I say that such a simple system is an idealized model of a complex system? Like complex systems in nature, cellular automata are composed of large numbers of simple components (i.e., cells), with no central controller, each of which communicates with only a small fraction of the other components. Moreover, cellular automata can exhibit very complex behavior that is difficult or impossible to predict from the cell update rule. Cellular automata were invented—like so many other good ideas—by John von Neumann, back in the 1940s, based on a suggestion by his colleague, the mathematician Stan Ulam. (This is a great irony of computer science, since cellular automata are often referred to as non -von-Neumann-style architectures, to contrast with the von-Neumann-style architectures that von Neumann also invented.)

And even if it were possible, the ensuing computation would be achingly slow, not to mention wasteful, since the huge parallel, non-von-Neumann-style computing resources of the cellular automaton would be used to simulate, in a very slow manner, a traditional von-Neumann-style computer. For these reasons, people don’t use Life (or other “universal” cellular automata) to perform real-world computations or even to model natural systems. What we really want from cellular automata is to harness their parallelism and ability to form complex patterns in order to achieve computations in a nontraditional way. The first step is to characterize the kinds of patterns that cellular automata can form. The Four Classes In the early 1980s, Stephen Wolfram, a physicist working at the Institute for Advanced Study in Princeton, became fascinated with cellular automata and the patterns they make. Wolfram is one of those legendary former child prodigies whom people like to tell stories about. Born in London in 1959, Wolfram published his first physics paper at age 15.

This book is also about complexity science, which is an interdisciplinary field (at the intersection of mathematics, computer science, and natural science) that focuses on discrete models of physical systems. In particular, it focuses on complex systems, which are systems with many interacting components. Complex systems include networks and graphs, cellular automata, agent-based models and swarms, fractals and self-organizing systems, chaotic systems, and cybernetic systems. These terms might not mean much to you at this point. We will get to them soon, but you can get a preview at http://en.wikipedia.org/wiki/Complex_systems. A New Kind of Science In 2002, Stephen Wolfram published A New Kind of Science, where he presents his and others’ work on cellular automata and describes a scientific approach to the study of computational systems. We’ll get back to Wolfram in Chapter 6, but I want to borrow his title for something a little broader. I think complexity is a “new kind of science” not because it applies the tools of science to a new subject, but because it uses different tools, allows different kinds of work, and ultimately changes what we mean by “science.”

Can you summarize one or more of the objections that philosophers and historians of science have raised to Popper’s claim? Do you get the sense that practicing philosophers think highly of Popper’s work? What Is This a Model Of? Some cellular automata are primarily mathematical artifacts. They are interesting because they are surprising, useful, or pretty, or because they provide tools for creating new mathematics (like the Church-Turing thesis). But it is not clear that they are models of physical systems. If they are, they are highly abstracted, which is to say that they are not very detailed or realistic. For example, some species of cone snail produce a pattern on their shells that resembles the patterns generated by cellular automata (see http://en.wikipedia.org/wiki/Cone_snail). It is natural to suppose that a CA is a model of the mechanism that produces patterns on shells as they grow.

Turing's Vision: The Birth of Computer Science by Chris Bernhardt

Ada Lovelace, Alan Turing: On Computable Numbers, with an Application to the Entscheidungsproblem, Albert Einstein, Andrew Wiles, British Empire, cellular automata, Claude Shannon: information theory, complexity theory, Conway's Game of Life, discrete time, Douglas Hofstadter, Georg Cantor, Gödel, Escher, Bach, Henri Poincaré, Internet Archive, Jacquard loom, John Conway, John von Neumann, Joseph-Marie Jacquard, Norbert Wiener, Paul Erdős, Turing complete, Turing machine, Turing test, Von Neumann architecture

First we look at Church’s λ-calculus (lambda calculus), then Post’s tag systems, and finally cellular automata. All of these have been shown to be able to do computations. In fact, rather surprisingly, all have computational power equivalent to Turing machines. We start with the λ-calculus. This plays an important role in computer science, especially in the design of computer languages. After our brief foray into λ-calculus we move on to tag systems. Tag systems are easy to describe, but despite their simplicity, they are able to do any computation. Their simplicity is often useful in proving the equivalence of computational systems. For example, the proof that cellular automata can do anything that Turing machines can do involves emulating Turing machines by tag systems. The final topic is the study one-dimensional cellular automata. These are interesting because they yield two-dimensional pictures that show the entire computation.

Quantum Computing since Democritus by Aaranson, The Beginning of Infinity: Explanations That Transform the World by Deutsch, and Gödel, Escher, Bach by Hofstadter are all fascinating. Cellular automata We only looked briefly looked at cellular automata, but they have a long and interesting history. They were first studied by Ulam and von Neumann as the first computers were built. Nils Barricelli was at Princeton during the 1950s and used the computer to simulate the interaction of cells. George Dyson’s Turing’s Cathedral gives a good historical description of this work John Conway, in 1970, defined Life involving two-dimensional cellular automata. These were popularized by Martin Gardner in Scientific American. William Poundstone’s The Recursive Universe is a good book on the history of these automata and how complexity can arise from simple rules.

Chapter 5 In addition to Turing’s approach, there are several different ways at looking at computation. In this chapter we pause to examine at three of these. We begin with the lambda calculus (λ-calculus) of Alonzo Church, then look at an example of a tag system, finally we consider cellular automata. These views of computation seem very different, but each perspective has its own strengths. The λ-calculus leads to programming languages; tag systems are useful for proving different systems equivalent; cellular automata give pictures of complete computations. After this brief detour we return to Turing’s arguments. Chapter 6 Up until now, machines have been described by diagrams. This chapter starts by showing how finite automata and Turing machines can be described by finite sequences of digits, called encodings.

However, expressing continuous formulas in this way is an inherent complication and would violate Einstein's dictum to express things "as simply as possible, but no simpler." So the real question is whether we can express the basic relationships that we are aware of in more elegant terms, using cellular-automata algorithms. One test of a new theory of physics is whether it is capable of making verifiable predictions. In at least one important way, that might be a difficult challenge for a cellular automata-based theory because lack of predictability is one of the fundamental features of cellular automata. Wolfram starts by describing the universe as a large network of nodes. The nodes do not exist in "space," but rather space, as we perceive it, is an illusion created by the smooth transition of phenomena through the network of nodes. One can easily imagine building such a network to represent "naive" (Newtonian) physics by simply building a three-dimensional network to any desired degree of granularity.

I don't have in hand, but I know he's there....What I see is so compelling that it can't be a creature of my imagination.62 In commenting on Fredkin's theory of digital physics, Wright writes, Fredkin ... is talking about an interesting characteristic of some computer programs, including many cellular automata: there is no shortcut to finding out what they will lead to. This, indeed, is a basic difference between the "analytical" approach associated with traditional mathematics, including differential equations, and the "computational" approach associated with algorithms. You can predict a future state of a system susceptible to the analytic approach without figuring out what states it will occupy between now and then, but in the case of many cellular automata, you must go through all the intermediate states to find out what the end will be like: there is no way to know the future except to watch it unfold....Fredkin explains: "There is no way to know the answer to some question any faster than what's going on. "...

It sounds like a good-news/bad-news joke: the good news is that our lives have purpose; the bas news is that their purpose is to help some remote hacker estimate pi to nine jillion decimal places. 63 Fredkin went on to show that although energy is needed for information storage and retrieval, we can arbitrarily reduce the energy required to perform any particular example of information processing. and that this operation has no lower limit.64 That implies that information rather than matter and energy may be regarded as the more fundamental reality.65 I will return to Fredkin's insight regarding the extreme lower limit of energy required for computation and communication in chapter 3, since it pertains to the ultimate power of intelligence in the universe. Wolfram builds his theory primarily on a single, unified insight. The discovery that has so excited Wolfram is a simple rule he calls cellular automata rules 110 and its behavior. (There are some other interesting automata rules, but rule 110 makes the point well enough.) Most of Wolfram's analyses deal with the simplest possible cellular automata, specifically those that involve just a one-dimensional line of cells, two possible colors (black and white), and rules based only on the two immediately adjacent cells. For each transformation, the color of a cell depends only on its own previous color and that of the cell on the left and the cell on the right.

Is there an even simpler system that exhibits a complexity that is easier to analyze? Cellular Automata Another colorful character with a scientifically serious approach to complexity, Stephen Wolfram (figure 13.1) was a wunderkind, the youngest person ever to earn a doctorate in physics from Caltech at the age of 20, and the founder of the Center for Complex Systems Research at the University of Illinois in 1986. Wolfram thought that neural networks were too complex and decided instead to explore cellular automata. The Age of Algorithms 197 Figure 13.1 Stephen Wolfram at his home in Concord, Massachusetts, standing on an algorithmically generated floor. Wolfram was a pioneer in complexity theory and showed that even simple programs can give rise to the complexities of the kind we encounter in the world. Courtesy of Stephen Wolfram. Cellular automata typically have only a few discrete values that evolve in time, depending on the states of the other cells.

In the past, such algorithms were handcrafted by mathematicians and computer scientists working like artisans in guilds. Stephen Wolfram automated the finding of algorithms for cellular automata by exhaustive search, starting with the simplest automata, some of which produced highly complex patterns. This insight can be summarized by Wolfram’s law, which states that you don’t have to travel far in the space of algorithms to find one that solves an interesting class of problems. This is like sending bots to play games like StarCraft on the Internet to try all possible strategies. According to Wolfram’s law, there should be a galaxy of algorithms somewhere in the universe of algorithms that can win the game. Wolfram focused on the space of cellular automata, a small subspace in the space of all possible algorithms. But what if cellular automata are atypical algorithms that exhibits more universality than other classes of algorithms?

are critically important for finding a configuration that displays complex patterns. How common are rules that generate complexity? Wolfram wanted to know the simplest cellular automata rule that could lead to complex behaviors and so he set out to search through all of them. Rules 0 to 29 produced patterns that would always revert to boring behaviors: all the cells would end up in a repeating pattern or some nested fractal pattern. But rule 30 produced unfolding patterns and rule 110 dazzled with continually evolving complex patterns (box 13.1).8 It was eventually proved that rule 110 was capable of universal computation; that is, some of the simplest of all possible cellular automata have the power of a Turing machine that can compute any computable function, so it is in principle as powerful as any computer. One of the implications of this discovery is that the remarkable complexity we find in living things could have evolved by sampling the simplest space of chemical interactions between molecules.

The mathematics of these reactions involves recursive computations emerging spontaneously at the edge of chaos. It looks as if nature is a lover of extreme sports. It adores pushing everything that is precious to the point of breaking up. This deeper link between the emergence of complex behaviour at criticality and recursive computations has also been demonstrated in digital computers using cellular automata, another great invention by John von Neumann. Cellular automata are patterns of 0s and 1s that evolve step-by-step according to a simple set of rules. A new pattern, or ‘generation’, of a cellular automaton emerges after each step. Points on the new patterns will be either 0 or 1 depending on their current value as well as the value of their neighbours. In the early 1980s, the English mathematician Stephen Wolfram conjectured that a particular cellular automaton called ‘Rule 110’ might be ‘Turing complete’,21 a conjecture that was later proved by Matthew Cook.

Platonic thinking, so deeply entrenched in mathematical culture, is evidently at play here! Nevertheless, the correlation between computation and life is indisputable. It is the interpretation of this connection that polarises empiricists and idealists. Perhaps the discovery of Rule 110 is one giant step towards the discovery of a general, mathematical, law for life. There are too many things about cellular automata that make them profoundly similar to physical, living, things. By operating near the edge of chaos, cellular automata evolve with time by responding to their changing environment. They look like a form of ‘artificial life’ existing in the computer that runs the calculations that make and sustain it. Could this artificial life evolve to the point of becoming conscious? And, if so, how similar would this artificial consciousness be to ours? Imagining true AI Let us summarise what we have explored so far.

The journey of the individual parts towards forming a self-organised system appears then to be algorithmically determined: they are ‘attracted’ to self-organisation and, ultimately, to life. We do not yet know whether this attraction is governed by a general law for biology. However, we have discovered something that seems to point towards such a law: Rule 110, a recursive algorithm that is Turing complete and lifelike – and there might be more.23 This profound correlation between cellular automata and biological phenomena suggests that life is governed by recursive computations, probably similar – or identical – to cellular automata. There is one more special feature of complex computations that is worth noting. They are fractal-like and scale-invariant. This means that they repeat themselves at every scale. From microscopic organisms to weather systems and the formation of galactic clusters nature creates similar patterns of organisation and behaviour.

Previous Table of Contents Next ----------- 20.7 Cellular Automata A new and novel idea, studied by Papua Guam [665], is the use of cellular automata in public-key cryptosystems. This system is still far too new and has not been studied extensively, but a preliminary examination suggests that it may have a cryptographic weakness similar to one seen in other cases [562]. Still, this is a promising area of research. Cellular automata have the property that, even if they are invertible, it is impossible to calculate the predecessor of an arbitrary state by reversing the rule for finding the successor. This sounds a whole lot like a trapdoor one-way function. 20.8 Other Public-Key Algorithms Many other public-key algorithms have been proposed and broken over the years.

Daemen suggests that anyone interested in improving MMB should first do an analysis of modular multiplication with respect to linear cryptanalysis and choose a new multiplication factor, and then make the constant C different for each round [402]. Then, improve the key scheduling by adding constants to the round keys to remove the bias. He’s not going to do it; he designed 3-Way instead (see Section 14.5). 13.11 CA-1.1 CA is a block cipher built on cellular automata, designed by Howard Gutowitz [677, 678, 679]. It encrypts plaintext in 384-bit blocks and has a 1088-bit key (it’s really two keys, a 1024-bit key and a 64-bit key). Because of the nature of cellular automata, the algorithm is most efficient when implemented in massively parallel integrated circuits. CA-1.1 uses both reversible and irreversible cellular automaton rules. Under a reversible rule, each state of the lattice comes from a unique predecessor state, while under an irreversible rule, each state can have many predecessor states.

Each exponent is the result of the computation with the previous block; the first exponent is given by an IV. Ivan Damgård designed a one-way hash function based on the knapsack problem (see Section 19.2) [414]; it can be broken in about 232 operations [290, 1232, 787]. Steve Wolfram’s cellular automata [1608] have been proposed as a basis for one-way hash functions. An early implementation [414] is insecure [1052, 404]. Another one-way hash function, Cellhash [384,404], and an improved version, Subhash [384,402, 405], are based on cellular automata; both are designed for hardware. Boognish mixes the design principles of Cellhash with those of MD4 [402, 407]. StepRightUp can be implemented as a hash function as well [402]. Claus Schnorr proposed a one-way hash function based on the discrete Fourier transform, called FFT-Hash, in the summer of 1991 [1399]; it was broken a few months later by two independent groups [403, 84].

“My incredible luck,” he bragged to von Neumann from Los Alamos in February 1952, “was evident in poker (8 successive + earnings) this year.”70 Four of the twentieth century’s most imaginative ideas for leveraging our intelligence—the Monte Carlo method, the Teller-Ulam invention, self-reproducing cellular automata, and nuclear pulse propulsion—originated with help from Stan. Three of the four proved to be wildly successful, and the fourth was abandoned before it had a chance. Monte Carlo was the realization, through digital computing, of what Maxwell could only imagine: a way to actually follow the behavior of a physical system at its elemental levels, as “if our faculties and instruments were so sharpened that we could detect and lay hold of each molecule and trace it through all its course.”71 The Teller-Ulam invention invoked a form of Maxwell’s demon to heat a compartment to a temperature hotter than the sun by letting a burst of radiation in, and then, for an equilibrium-defying instant, not letting radiation out. Ulam’s self-reproducing cellular automata—patterns of information persisting across time—evolve by letting order in but not letting order out.

“Information was never ‘volatile’ in transit; it was as secure as an acrophobic inchworm on the crest of a sequoia.” Data were handled the way ships are moved through locks in a canal. “We enjoyed some interesting speculative discussions with von Neumann at this time about information propagation and switching among hypothetical arrays of cells,” remembers Bigelow, “and I believe that some germs of his later cellular automata studies may have originated here.”20 “We did not move information from one place to another except in a positive way,” emphasizes James Pomerene. “That is used absolutely universally now. I think we were the first to do it. And I regret that we didn’t patent it.” Patentable inventions were being generated right and left. “The original patent agreement provided that the Institute would have title to patents, but they would pay to the inventor all royalties in excess of their costs,” Pomerene adds.

They evidently had a long conversation on a bench in Central Park, leaving no record of their discussion of the Ivy Mike test, but a subsequent exchange of letters hinted at the conversation having extended to the possibility of a digital universe being brought to life. “Only because of our conversation on the bench in Central Park I was able to understand…[that] given is an actually infinite system of points (the actual infinity is worth stressing because nothing will make sense on a finite no matter how large model),” noted Ulam, who then sketched out how he and von Neumann had hypothesized the evolution of Turing-complete (or “universal”) cellular automata within a digital universe of communicating memory cells. The definitions had to be made mathematically precise: A “universal” automaton is a finite system which given an arbitrary logical proposition in form of (a linear set L) tape attached to it, at say specified points, will produce the true or false answer. (Universal ought to have relative sense: with reference to a class of problems it can decide.)

Inspired by Turing’s papers on computation, von Neumann also came up with the modern conception of Babbage’s ‘store’ and ‘mill’ computer structure, in what is now called the ‘von Neumann architecture’, the architecture at the heart of almost all modern computers. Amongst this world-changing productivity, von Neumann also speculated about how computer programs, like genetic organisms, might be able to self-replicate. His ‘cellular automata’ theory closely parallels the actual replication methods of biological DNA, despite the fact that von Neumann’s work was done in advance of the actual structure of DNA being discovered by Watson and Crick in 1953.7 At the same time, statistician George Box suggested ‘evolutionary operations’8 as a methodology for optimizing industrial processes in the late 1950s, though he never implemented the procedure as a computer algorithm, and there are a number of other scientists who also struck close to the ideas that would eventually emerge as evolutionary computation.

So the evolutionary metaphor for computational algorithms was a firmly set context from the very start of computation, but it wasn’t until the late 1960s that the foundational idea of evolutionary algorithms really began to gain traction in various research centres around the world.9 In Germany, a group led by Ingo Rechenberg developed a kind of optimization algorithm called ‘evolutionsstrategies’.10 On the West Coast of the US, a group led by Lawrence Fogel developed another called ‘evolutionary programming’.11 And, at the University of Michigan, John Holland pioneered another form called ‘genetic algorithms’.12 Of all of these researchers, it is John Holland who has the most direct connection with Von Neumann’s early theories, since his PhD supervisor was Arthur Burks,13 who worked on the ENIAC engineering team and extended von Neumann’s work on ‘cellular automata’.14 Furthermore, Holland was granted the first PhD in computer science and went on to teach at the University of Michigan where he advised many students on PhDs that involved evolutionary computation, including my own PhD supervisor, David Goldberg. Goldberg wrote the first textbook on genetic algorithms while I was a part of his research group in 1989. Lots of work from Dave’s research group was in the text, including some of my own, and I helped edit the book’s first draft (by making red ink marks on a ream of dot matrix paper).

These models and algorithms seem to imply that, to be effective, evolution requires a balance between the discipline of using the best-known idea and the chaos of mixing ideas up. Other scientific studies also show that striking a precise balance between the two may be the vital characteristic of living systems. The term edge of chaos was first used by the SFI researchers Doyne Farmer and Chris Langton, while looking at cellular automata models, simplified algorithms invented by John von Neumann to represent self-replicating biology.4 While experimenting with parameters that controlled these programs, they observed that for some parameter settings, the algorithms would settle into uninteresting equilibria, essentially static states. For others, the algorithms just generated complete randomness, never seeming to settle down into any recognizable patterns.

Most incompatibilists would find the concept of free will to also be incompatible with our decisions’ being essentially accidental. Free will seems to imply purposeful decision making. Dr. Wolfram proposes a way to resolve the dilemma. His book A New Kind of Science (2002) presents a comprehensive view of the idea of cellular automata and their role in every facet of our lives. A cellular automaton is a mechanism in which the value of information cells is continually recomputed as a function of the cells near it. John von Neumann created a theoretical self-replicating machine called a universal constructor that was perhaps the first cellular automaton. Dr. Wolfram illustrates his thesis with the simplest possible cellular automata, a group of cells in a one-dimensional line. At each point in time, each cell can have one of two values: black or white. The value of each cell is recomputed for each cycle. The value of a cell for the next cycle is a function of its current value as well as the value of its two adjacent neighbors.

The reason that his book is titled A New Kind of Science is because this theory contrasts with most other scientific laws. If there is a satellite orbiting Earth, we can predict where it will be five years from now without having to run through each moment of a simulated process by using the relevant laws of gravity and solve where it will be at points in time far in the future. But the future state of class IV cellular automata cannot be predicted without simulating every step along the way. If the universe is a giant cellular automaton, as Dr. Wolfram postulates, there would be no computer big enough—since every computer would be a subset of the universe—that could run such a simulation. Therefore the future state of the universe is completely unknowable even though it is deterministic. Thus even though our decisions are determined (because our bodies and brains are part of a deterministic universe), they are nonetheless inherently unpredictable because we live in (and are part of) a class IV automaton.

Like the checkers on a checkerboard, tokens that each represent a collection of molecules get moved among sites based on how the neighboring sites are occupied. This idea has come to be known as Cellular Automata (CAs). From the 1970s onward, the group of Ed Fredkin, Tomaso Toffoli, and Norm Margolus at MIT started to make special-purpose computers designed for CAs. Because these machines entirely dispense with approximations of continuous functions, they can be much simpler and faster. And because a Turing machine can be described this way, a CA can do anything that can be done with a conventional computer. A cellular automata model of the universe is no less fundamental than one based on calculus. It's a much more natural description if a computer instead of a pencil is used to work with the model. BIT BELIEFS + 133 And the discretization solves another problem: a continuous quantity can represent an infinite amount of information.

In particular, the monads’ production rule scheme clearly presages the modern concept of cellular automata. Quoting from Mercer’s work: “The Production Rule of F is a rule for the continuous production of the discrete states of F so that it instructs F about exactly what to think at every moment of F’s existence. Following Leibniz’s suggestion, if F exists from t1 to tn and has a different thought at each moment of its existence, then at every moment, there will be an instruction about what to think next. The present thought occurring at t1, together with the Production Rule, will determine what F will think at t2.” Combined with the monadic property of being able to perceive the states of all other monads, this comes close to being a mathematically formal definition of cellular automata, a branch of mathematics generally agreed to have been invented by Stanislaw Ulam and John von Neumann during the 1940s as an outgrowth of work at Los Alamos.

Combined with the monadic property of being able to perceive the states of all other monads, this comes close to being a mathematically formal definition of cellular automata, a branch of mathematics generally agreed to have been invented by Stanislaw Ulam and John von Neumann during the 1940s as an outgrowth of work at Los Alamos. The impressive capabilities of such systems have, in subsequent decades, drawn the attention of many luminaries from the worlds of mathematics and physics, some of whom have proposed that the physical universe might, in fact, consist of cellular automata carrying out a calculation—a hypothesis known as Digital Physics, or It from Bit. 4. Leibniz insisted that each monad perceived the states of all of the others, a premise that runs counter to intuition, given that this would seem to require that an infinite amount of information be transmitted to and stored in each monad. Of all the claims of monadology, this must have seemed the easiest to refute a hundred years ago. Since then, however, it has been given a new lease on life by quantum mechanics.

That’s a description of how all science has been done for a long time. He’s making the argument that a lot of science doesn’t necessarily fit that mold: biological science, psychology. There are plenty of cases you can point to, even in mathematics, where being able to break things down into its smallest components doesn’t really get you anywhere. It doesn’t give you an explanation that’s really worth anything. If you look at cellular automata, for example: Sure, each automaton can be explained as a unit, but that’s not what’s interesting. What’s interesting is the really complicated emergent behaviors that you can get out of a whole bunch of these things acting at once. There’s really no grid to cross that gap. Yet we’re often led to believe that these things are better understood than they are. Biologists complain that it doesn’t make much sense to talk about having “decoded” the genome when how the coding in genes is used to make proteins is still something of a mystery.

Emergence relates to the dynamic nature of interactions between components in a system (Gallegati and Kirman, 2012). The dynamic character of emergent phenomena is not a property of a pre-established, given whole - but arises and becomes apparent as a complex system evolves over time (Goldstein, 1999). Complexity in a system can arise, after all, from simple rules - this is seen in examples such as cellular automata, neural networks and genetic algorithms (Refer Notes). This is because of the non-linearity of the systems relations. As the system becomes complex, emergence manifests itself in the form of self- organization. In other words, no external forces are needed for the system to take on certain properties and traits and these systemic properties arise from far-fromequilibrium conditions (Morçöl, 2008).

All equations are closely based on assumptions that households maximize their own welfare and firms maximize profits. Examples are models developed by Kydland and Prescott and by Christiano and Eichenbaum. Vector autoregression (VAR) models employ a small number of estimated equations to summarize the dynamic behaviour of the entire macroeconomy, with few restrictions from economic theory beyond the choice of variables to include in the model. Sims is the original proponent of this type of model. Cellular automata (CA): “Automaton” (plural: “automata") is a technical term used in computer science and mathematics for a hypothetical machine that changes its internal state based on inputs and its previous state. (Sayama, 2015). A cellular automaton consists of a regular grid of cells, each in one of a finite number of states, such as on and off. Each cell is surrounded by a set of cells called it neighbourhood.

He's not sure Pamela ever let him see her fully naked: She thought skin was more sexy when it was covered. Annette squeezes him again, and he stiffens. "More!" By the time they finish, he's aching, and she shows him how to use the bidet. Everything is crystal clear, and her touch is electrifying. While she showers, he sits on the toilet seat lid and rants about Turing-completeness as an attribute of company law, about cellular automata and the blind knapsack problem, about his work on solving the Communist Central Planning problem using a network of interlocking unmanned companies. About the impending market adjustment in integrity, the sinister resurrection of the recording music industry, and the still-pressing need to dismantle Mars. When she steps out of the shower, he tells her that he loves her. She kisses him and slides his glasses and earpieces off his head so that he's really naked, sits on his lap, and fucks his brains out again, and whispers in his ear that she loves him and wants to be his manager.

Each of these companies – and there are currently more than sixteen thousand of them, although the herd is growing day by day – has three directors and is the director of three other companies. Each of them executes a script in a functional language Manfred invented; the directors tell the company what to do, and the instructions include orders to pass instructions on to their children. In effect, they are a flock of cellular automata, like the cells in Conway's Game of Life, only far more complex and powerful. Manfred's companies form a programmable grid. Some of them are armed with capital in the form of patents Manfred filed, then delegated rather than passing on to one of the Free Foundations. Some of them are effectively nontrading, but occupy directorial roles. Their corporate functions (such as filing of accounts and voting in new directors) are all handled centrally through his company-operating framework, and their trading is carried out via several of the more popular B2B enabler dot-coms.

Boris lumbers round in place to face her; today he's wearing a velociraptor, and they don't turn easily in confined spaces. He snarls irritably: "Give me some space!" He coughs, a threatening noise from the back of his wattled throat, "Searching the sail's memory now." The back of the soap-bubble-thin laser sail is saturated with tiny nanocomputers spaced micrometers apart. Equipped with light receptors and configured as cellular automata, they form a gigantic phased-array detector, a retina more than a hundred meters in diameter. Boris is feeding them patterns describing anything that differs from the unchanging starscape. Soon the memories will condense and return as visions of darkness in motion – the cold, dead attendants of an aborted sun. "But where is it going to be?" asks Sadeq. "Do you know what you are looking for?"

These originals were transformative, but the postwar variations are limited, obsolete, and if used doctrinally, dangerous. The Austrian understanding of the superiority of free markets over central planning is sound. Still, the Austrian school needs updating using new science and twenty-first-century technology. Christopher Columbus was the greatest dead-reckoning navigator ever. Yet no one disputes he would use GPS today. If Friedrich Hayek were alive, he would use new instruments, network theory, and cellular automata to refine his insights. His followers should do no less. Neo-Keynesian models are the reigning creed. Interestingly, they have little to do with John Maynard Keynes. He was above all a pragmatist; those who follow in his name are anything but. Keynes advocated for gold in 1914, counseled for a higher gold price in 1925, opposed gold in 1931, and offered a modified gold standard in 1944. Keynes had pragmatic reasons for each position.

There may be a cause-and-effect relationship between catalyst and collapse. Still, it is too small to observe and the timing is difficult to forecast. Predicting market crashes is like predicting earthquakes. One may be certain the event will occur, and can estimate its magnitude, yet one will never know exactly when. Laboratory science, in particular sand pile experiments (similar to a snowflake-avalanche dynamic) and computer simulations using cellular automata, reveal degree distributions of extreme events. Still, a million experiments will not let you predict which particular grain of sand causes a certain sand pile to collapse. Systemic instability, not an individual catalyst, destroys your wealth. Anxious investors should not focus on snowflakes, they should stay alert for an avalanche. Nonetheless, the search for snowflakes is seductive. The most sensational snowflake may be a publicized failure to deliver physical gold by a prominent bank.

Schumpeter’s consideration of capitalism’s rise and fall, while not specific to one civilization, is the kind of study to which complexity theory lends valuable tools. Schumpeter eschewed Keynesian models because of the artifice in holding most variables constant while monotonically isolating one as the “cause” of the phenomena under study. Today a twenty-first-century mélange of a Schumpeterian long view and massive computing power—unavailable to Schumpeter—allows for a rapid expansion of recursive functions and simulation of human action via cellular automata. Schumpeter would surely look benignly on such efforts as a reasonable simulacrum of his deep historical processes. Society stands on Schumpeter’s shoulders with new tools of complexity theory to look over a ridgeline at the rise of socialism and fascism, one and the same.

Epigenetics: How Environment Shapes Our Genes by Richard C. Francis

As we have seen, the epigenetic changes in gene expression that determine a cell’s fate are largely determined by the position of that cell in the developing embryo. Therefore, it would be more apt to say that the genes are programmed by cellular interactions. There are other, very minimalist senses of “program” that have become popular in the fields of artificial intelligence and artificial life.26 On this minimalist notion of program, a program provides a few basic rules, and the robots or cellular automata take it from there through interactions with their neighbors and the rest of their environment. But the idea of a central director is gone. This minimalist sense of program looks a lot like epigenesis. So the preformationist notion of an epigenetic (or genetic) program is either false or too squishy to be distinguished from epigenesis. In either case, we would be better served to drop the “program” metaphor altogether, and with it, the temptation to think of genes as software.

From these stem cells, they generated normal-appearing mice. 24. Kulesa, Kasemeier-Kulesa, et al. (2006); Hendrix, Seftor, et al. (2007). 25. Collas (2010) is typical in this regard, in the context of cellular differentiation. 26. For the minimalist notion of programming in situated robotics, see Hendriks-Jansen (1996). Wolfram (2002) is an expanded, semi-mystical view of the significance of a minimalist program, motivated by Wolfram’s research on cellular automata. 27. Passier and Mummery (2003). 28. Moreover, there are subtle differences between embryonic stem cells (ESCs) and induced embryonic stem cells (iPSCs) that are clinically relevant. For example, ESCs have proved much more efficient in promoting neuronal redifferentiation than iPSCs have (Tokumoto, Ogawa, et al. 2010). 29. This is how Conrad Waddington, who coined the term epigenetic, describes its derivation: “Some years ago I introduced the word ‘epigenetic,’ derived from the Aristotelian word ‘epigenesis,’ which had more or less passed into disuse, as a suitable name for the branch of biology which studies the causal interactions between genes and their products which bring the phenotype into being” (Waddington 1968). 30.

These copies would immediately set about making further copies, underwriting an exponential increase in production capacity. Von Neumann’s constructors existed in an entirely virtual universe of possibility. At the time he imagined them, there wasn’t enough computing power in the world to simulate their behavior, let alone physically realize them as anything other than painstakingly inked grids of pen on paper, so-called cellular automata.2 But with its implication of a continuously and geometrically expanding productivity, his vision of a universal constructor inspired generations of engineers. Sometime around the turn of the twenty-first century, one of them—a mechanical engineering professor at the University of Leeds named Adrian Bowyer, troubled by the thought of a world riven by material scarcity—finally took von Neumann at his word.

As a general rule, the more symmetries you have, the simpler things become. 110 This whole checkerboard-worlds idea sometimes goes by the name of cellular automata. A cellular automaton is just some discrete grid that follows a rule for determining the next row from the state of the previous row. They were first investigated in the 1960s, by John von Neumann, who is also the guy who figured out how entropy works in quantum mechanics. Cellular automata are fascinating for many reasons having little to do with the arrow of time; they can exhibit great complexity and can function as universal computers. See Poundstone (1984) or Shalizi (2009). Not only are we disrespecting cellular automata by pulling them out only to illustrate a few simple features of time reversal and information conservation, but we are also not speaking the usual language of cellular-automaton cognoscenti.

Most mathematicians agree that mathematics as we know it has evolved from the basic branches of geometry and arithmetic that were practiced by the ancient Babylonians, Egyptians, and Greeks. However, was it truly inevitable that mathematics would start with these particular disciplines? Computer scientist Stephen Wolfram argued in his massive book A New Kind of Science that this was not necessarily the case. In particular, Wolfram showed how starting from simple sets of rules that act as short computer programs (known as cellular automata), one could develop a very different type of mathematics. These cellular automata could be used (in principle, at least) as the basic tools for modeling natural phenomena, instead of the differential equations that have dominated science for three centuries. What was it, then, that drove the ancient civilizations toward discovering and inventing our special “brand” of mathematics? I don’t really know, but it may have had much to do with the particulars of the human perceptual system.

He is the creator of the symbolic computation program Mathematica and its programming language, Wolfram Language, as well as the knowledge engine Wolfram|Alpha. He is also the author of A New Kind of Science. The following is an edited transcript from a live interview with him conducted in December 2015. Over nearly four decades, Stephen Wolfram has been a pioneer in the development and application of computational thinking and responsible for many innovations in science, technology, and business. His 1982 paper “Cellular Automata as Simple Self-Organizing Systems,” written at the age of twenty-three, was the first of numerous significant scientific contributions aimed at understanding the origins of complexity in nature. It was around this time that Stephen briefly came into my life. I had established The Reality Club, an informal gathering of intellectuals who met in New York City to present their work before peers in other disciplines.

But even with a smart enough machine and smart enough mathematics, we can’t get to the endpoint without going through the steps. Some details are irreducible. We have to irreducibly follow those steps. That’s why history means something. If we could get to the endpoint without going through the steps, history would be, in some sense, pointless. So it’s not the case that we’re intelligent and everything else in the world is not. There’s no enormous abstract difference between us and the clouds or us and the cellular automata. We cannot say that this brainlike neural network is qualitatively different from this cellular-automaton system. The difference is a detailed difference. This brainlike neural network was produced by the long history of civilization, whereas the cellular automaton was created by my computer in the last microsecond. The problem of abstract AI is similar to the problem of recognizing extraterrestrial intelligence: How do you determine whether or not it has a purpose?

Chaos: Making a New Science by James Gleick

Benoit Mandelbrot, business cycle, butterfly effect, cellular automata, Claude Shannon: information theory, discrete time, Edward Lorenz: Chaos theory, experimental subject, Georg Cantor, Henri Poincaré, Isaac Newton, iterative process, John von Neumann, Louis Pasteur, mandelbrot fractal, Murray Gell-Mann, Norbert Wiener, pattern recognition, Richard Feynman, Stephen Hawking, stochastic process, trade route

When Yaneer Bar-Yam wrote a kilopage textbook, Dynamics of Complex Systems, in 2003, he took care of chaos proper in the first section of the first chapter. (“The first chapter, I have to admit, is 300 pages, okay?” he says.) Then came Stochastic Processes, Modeling Simulation, Cellular Automata, Computation Theory and Information Theory, Scaling, Renormalization, and Fractals, Neural Networks, Attractor Networks, Homogenous Systems, Inhomogenous Systems, and so on. Bar-Yam, the son of a high-energy physicist, had studied condensed matter physics and become an engineering professor at Boston University, but he left in 1997 to found the New England Complex Systems Institute. He had been exposed to Stephen Wolfram’s work on cellular automata and Robert Devaney’s work in chaos and discovered that he was less interested in polymers and superconductors than in neural networks and—he says this with no sense of grandiosity—the nature of human civilization.

She'd spoken to Martin about it, piecing together his information with her own. Together they'd pieced together a terrifying hypothesis. "Herman was unusually vague about it," Martin admitted. "Normally he has a lot of background detail. Every word means something. But it's as if he doesn't want to say too much about the Festival. They're—he called them, uh, glider-gun factories. I don't know if you know about Life—" "Cellular automata, the game?" "That's the one. Glider guns are mobile cellular automata. There are some complex life structures that replicate themselves, or simpler cellular structures; a glider-gun factory is a weird one. It periodically packs itself into a very dense mobile system that migrates across the grid for a couple of hundred squares, then it unpacks itself into two copies that then pack down and fly off in opposite directions. Herman said that they're a real-space analogue: he called them a Boyce-Tipler robot.

His description (posthumously published, 1966) of how an automaton would read its own blueprint and then copy it into its new creation anticipated in impressive detail many of the later discoveries about the mechanisms of DNA expression and replication, but in order to make his proof of the possibility of a self-reproducing automaton mathematically rigorous and tractable, von Neumann had switched to simple, two-dimensional abstractions, now known as cellular automata. Conway's Life-world cells are a particularly agreeable example of cellular automata. Conway and his students wanted to confirm von Neumann's proof in detail by actually constructing a two-dimensional world with a simple physics in which such a self-replicating construction would be a stable, working structure. Like von Neumann, they wanted their answer to be as general as possible, and hence as independent as possible of actual (Earthly?

The task of the wise God required to put this world into motion is a task of discovery, not creation, a job for a Newton, not a Shakespeare. What Newton found — and what Conway found — are eternal Platonic fixed points that anybody else in principle could have discovered, not idiosyncratic creations that depend in any way on the particularities of the minds of their authors. If Conway had never turned his hand to designing cellular-automata worlds — if Conway had never even existed — some other mathematician might very well have hit upon exactly the Life world that Conway gets the credit for. So, as we follow the Darwinian down this path, God the Artificer turns first into God the Lawgiver, who now can be seen to merge with God the Lawfinder. God's hypothesized contribution is thereby becoming less personal — and hence more readily performable by something dogged and mindless!

One possible path is bringing existing non-AI and non-blockchain rule-based systems onto the blockchain to further automate and empower their operations. This could include systems like chaining together simple if-this-then-that (or IFTTT) behavior and the open source Huginn platform for building agents that monitor situations and act on your behalf. A second possible path is implementing programmatic ideas from AI research fields such as Wolfram’s cellular automata, Conway’s Game of Life, Dorigo’s Ant Colony Optimization and Swarm Intelligence, Andy Clark’s embodied cognitive robots, and other general agent-based systems. Chapter 3. Blockchain 3.0: Justice Applications Beyond Currency, Economics, and Markets Blockchain Technology Is a New and Highly Effective Model for Organizing Activity Not only is there the possibility that blockchain technology could reinvent every category of monetary markets, payments, financial services, and economics, but it might also offer similar reconfiguration possibilities to all industries, and even more broadly, to nearly all areas of human endeavor.

Conway’s “game” isn’t so much a game played by people as it is a mathematical experiment. The game is an example of emergent behavior because there are only four simple rules that generate an amazing amount of complexity. Conway’s game is also Turing Complete, which means that (given the right initial conditions) the game is as powerful as any “real” computer.

One of the latter was Margaret Hamilton, a young MIT coder who would later become a famous programmer engineering mission-critical NASA systems, helping to land Apollo missions safely on the moon. Back in those early MIT days, she was trying to run a weather-simulation model, but it kept on crashing. Why? Eventually Hamilton learned it was because the hackers had rejiggered the computer’s assembler to suit their desires and hadn’t switched it back. They wanted to muck around with pretty cellular automata; she was trying to do weather science. But the hackers simply hadn’t appeared to think about the repercussions their tinkering had for other people. These guys were companionable with each other but mostly uninterested in talking about their own or others’ inner lives. “I spent my lifetime walking around talking like a robot, talking to a bunch of other robots,” as one of them later said with a sigh.

When you take cheap machines that can do nearly anything you tell them to and hand them over to teenagers with essentially no adult supervision—because their parents had no idea what computers were—you create the infinite-monkeys experiment of software. Soon, teenage coders were cobbling together everything and anything: chatbots that would curse and swear, spellbinding forms of artificial life known as “cellular automata,” casino games, little databases and accounting programs, computer music, and endless varieties of games. Everingham was desperate to join this scene. He was from a lower-middle-class family whose parents couldn’t afford to buy him a computer. So he began frantically picking up every spare job he could—mowing lawns, then shoveling snow when winter came—until he’d saved enough, with a contribution from his mother, to get his own VIC-20.

One approach has been to use non-silicon materials in chips for the first time.53 Another possibility is to move from the current paradigm of ‘2D’ integrated circuits—where transistors are arranged side-by-side on a wafer of silicon—to a ‘3D’ approach where transistors are piled high.54 Another approach might be to abandon silicon altogether in favour of carbon nanotubes as the material for building even smaller, more efficient transistors.55 Yet another approach, currently taken by Google, would be to use more special-purpose computer chips for particular functions—chips that do fewer things but much faster.56 Microsoft increasingly uses a new type of chip that could combine much greater speed with flexibility.57 Looking further ahead, engineers at Google and elsewhere are already hard at work developing ‘quantum computers’ which, in certain tasks, are expected to be able to compute well beyond the capabilities of classical computers.58 Another possible alternative to OUP CORRECTED PROOF – FINAL, 26/05/18, SPi РЕЛИЗ ПОДГОТОВИЛА ГРУППА "What's News" VK.COM/WSNWS Increasingly Capable Systems 41 silicon might be to use 2D graphene-like compounds and ‘spintronic’ materials, which compute by harnessing the spin of electrons rather than moving them around.59 There’s also the growing field of ­neuroelectronics, which seeks to reverse-engineer the neural networks of the human brain while potentially requiring less power than silicon.60 In the still longer term, Quantum Dot Cellular Automata (‘QDCA’) technology may yield an unimaginably small semiconductor capable of doing the work of a transistor, but using much less power and wasting little energy.61 Many of these technologies are still in their infancy and nothing certain can be said about the future of Moore’s Law. But the least likely outcome is that computer science simply grinds to a halt, with hungry young Silicon Valley engineers hanging up their circuit boards and heading for retirement.

‘It was so incompetent when faced with any real-world problems, I didn’t feel I needed to learn about it.’ For years, however, he had been searching for what he refers to as the ‘problem of a lifetime’ to sink his teeth into. An interest in the brain made him consider everything from primate neuroanatomy and insect flight behaviour, to learning in the rat hippocampus or curing Alzheimer’s disease. For a while, Hopfield was fascinated by cellular automata and the prospect of robots that could build copies of themselves. However, after months of research, it led him to a dead end. ‘It is surprisingly difficult to give up on a wrong idea that has been nurtured for a year,’ Hopfield says. But the idea of creating a model of life inside a computer stayed with him. He was fascinated by the idea of using a network to accomplish a task which the brain does rapidly and easily, but which computers were incapable of.

There has been a storm around work by Martin Nowack and his colleagues (which include the biologist E. O. Wilson) about the terminal flaws in the selfish gene theory.fn2 The question is: could it be that much of what we have read about the advances in behavioral sciences is nonsense? Odds are it is. Many people have been accused of racism, segregationism, and somethingism without merit. Using cellular automata, a technique similar to renormalization, the late Thomas Schelling showed a few decades ago how a neighborhood can be segregated without a single segregationist among its inhabitants. ZERO-INTELLIGENCE MARKETS The underlying structure of reality matters much more than the participants, something policymakers fail to understand. Under the right market structure, a collection of idiots produces a well-functioning market.

The Delicate Sound of a Combinatorial Explosion… We’ve introduced the problem and sketched out a rudimentary solution in just a few pages, but imagine how a real system like this might evolve over an extended period of months or even years with a team of people involved. It’s easy to see how the complexity could be overlooked or taken for granted as the nature of the problem we set out to solve. A system can start out simple, but very quickly become complex. This fact has been deeply explored in the study of complex systems and cellular automata. To see this idea in action, consider a classic technique for defining a complex graphical object by starting with two simple objects: “One begins with two shapes, an initiator and a generator…each stage of the construction begins with a broken line and consists in replacing each straight interval with a copy of the generator, reduced and displaced so as to have the same end points as those of the interval being replaced.”

So here was a promising idea, but it just didn’t quite work in the long run. I pulled some of those ideas into UML, but data flow architecture doesn’t seem to replace von Neumann architecture in most cases. So I had my shot and didn’t quite make it. There are also cellular automata. I think over half of my fellow grad students tried to build on them a highly parallel computer. That has to be the right approach, because that’s how the universe is constructed. (Or maybe not. Modern physics is stranger than fiction. The latest speculations suggest that space and time arise out of something more primitive.) But cellular automata seem suited to only certain geometric problems, very important problems to be sure, but not general-case problems. People haven’t figured out how to program them for the general case. Maybe there is no general case. The critical issue seems to be the interface between control flow and data structure.

You get this from the human-computer dialogues: And this from the human-human dialogues: Now if that difference isn’t night and day, I don’t know what is. Over. 1. Some equations (the Newtonian parabolas that projectiles follow, for instance) are such that you can just plug in any old future value for time and get a description of the future state of events. Other calculations (e.g., some cellular automata) contain no such shortcuts. Such processes are called “computationally irreducible.” Future time values cannot simply be “plugged in”; rather, you have to run the simulation all the way from point A to point Z, including all intermediate steps. Stephen Wolfram, in A New Kind of Science, attempts to reconcile free will and determinism by conjecturing that the workings of the human brain are “irreducible” in this way: that is, there are no Newtonian-style “laws” that allow us shortcuts to knowing in advance what people will do.

As well, when Maxis was still a public company, Braun had shown Wright a 1985 Activision game for the Apple II called Little Computer People. Little Computer People was occasionally hilarious and featured a slow-moving cartoonlike character called Darren who would write you letters saying, “I have many hobbies that occupy my time.” To prove it, he watched TV, exercised, and searched for someone to live in his computer with him. Finally, Wright was impressed with John Horton Conway’s theories of cellular automata, which were espoused in The Game of Life. In his 1970s simulation game, Conway showed that you could emulate the complex patterns of the birth and death of organisms living together in society—and everything in between. All these combined to influence Wright as he dreamed up a project whose working title was Home Tactics, the Experimental Domestic Simulator. Wright later tweaked the name to the slightly more appealing Dollhouse.

AND, OR and NOT can all be implemented using NOR gates, so NOR can do everything, and in fact it’s all some microprocessors use. So why can’t it be the Master Algorithm? It’s certainly unbeatable for simplicity. Unfortunately, a NOR gate is not the Master Algorithm any more than a Lego brick is the universal toy. It can certainly be a universal building block for toys, but a pile of Legos doesn’t spontaneously assemble itself into a toy. The same applies to other simple computation schemes, like Petri nets or cellular automata. Moving on to more sophisticated alternatives, what about the queries that any good database engine can answer, or the simple algorithms in a statistical package? Aren’t those enough? These are bigger Lego bricks, but they’re still only bricks. A database engine never discovers anything new; it just tells you what it knows. Even if all the humans in a database are mortal, it doesn’t occur to it to generalize mortality to other humans.

The way the task was accomplished by living organisms of the type found on earth was only one way it could be done. In principle, the task could be done by a machine that could follow a plan, because the plan, and not the mechanism that carried it out, was a part of the system with the special, heretofore mysterious property that distinguished life from nonliving matter. Von Neumann approached "cellular automata" on an abstract level, just as Turing did with his first machines. As early as 1948, he showed that any self-replicating system must have raw materials, a program that provides instructions, an automaton that follows the instructions and arranges the symbols in the cells of a Turing-type machine, a system for duplicating instructions, and a supervisory unit -- which turned out to be an excellent description of the DNA direction of protein synthesis in living cells.

Alan Turing, for example, had written about the possibility the previous year, to receptive audiences on both sides of the Atlantic. McCarthy was thinking about intelligence as a mathematical abstraction rather than something realizable—along the lines of Turing—through building an actual machine. It was an “automaton” notion of creating human intelligence, but not of the kind of software cellular automata that von Neumann would later pursue. McCarthy focused instead on an abstract notion of intelligence that was capable of interacting with the environment. When he told von Neumann about it, the scientist exclaimed, “Write it up!” McCarthy thought about the idea a lot but never published anything. Years later he would express regret at his inaction. Although his thesis at Princeton would focus on differential equations, he also developed an interest in logic, and a major contribution to the field of artificial intelligence would later come from his application of mathematical logic to common sense reasoning.

“I suppose ants can flank,” I said, though I sensed that it was a trick question and that Lio was flanking me with words at this very moment. “Why not?” “By accident, of course they can! You look down on it from above and say, ‘Oh, that looked like flanking.’ But if there’s no commander to see the field and direct their movements, can they really perform coordinated maneuvers?” “That’s a little like Saunt Taunga’s Question,” I pointed out (“Can a sufficiently large field of cellular automata think?”). “Well, can they?” “I’ve seen ants work together to carry off part of my lunch, so I know they can coordinate their actions.” “But if I’m one of a hundred ants all pushing on the same raisin, I can feel the raisin moving, can’t I—so the raisin itself is a way that they communicate with one another. But, if I’m a lone ant on a battlefield—” “Thistlehead, it’s Provener.” “Okay,” he said, and turned his back on me and started walking.

The Orithenans had used a system of computational chanting that, it was plain to see, was rooted in traditions that their founders had brought over from Edhar. To that point, it was clearly recognizable to any Edharian. It was a way of carrying out computations on patterns of information by permuting a given string of notes into new melodies. The permutation was done on the fly by following certain rules, defined using the formalism of cellular automata. After the Second Sack reforms, newly computerless avout had invented this kind of music. In some concents it had withered away, in others mutated into something else, but at Edhar it had always been practiced seriously. We’d all learned it as a sort of children’s musical game. But at Orithena they had been doing new things with it, using it to solve problems. Or rather to solve a problem, the nature of which I didn’t understand yet.

From Boris Kerner, The Physics of Traffic: Empirical Freeway Pattern Features, Engineering Applications, and Theory (Berlin: Springer, 2004), p. 69. each car behind it will stop: One simulation compared the “oscillations” and “amplifications” found in stop-and-go traffic to those found in queues. “Perturbations” in the queue, or the way people stopped and started, were often observed to grow larger from the front to the back of the queue in simulators using cellular automata. See Bongsoo Son, Tawan Kim, and Yongjae Lee, “A Simulation Model of Congested Traffic in the Waiting Line,” Computational Science and Its Applications: ICCSA 2005, vol. 3481 (2005), pp. 863–69. the harder it is to predict: An interesting parallel has been drawn between the way nonlinear traffic flows behave and the way supply chains work in the world of business. Supply chains suffer from what has been called the “bullwhip effect”—the farther a supplier is from the consumer, the higher the potential for variability (e.g., oversupply or undersupply).

The statisticians and cryptographers and physicists and computer scientists go to work. There is structure here; it needs only to be unraveled. The masters of causality search for conditional independence, screening-off and Markov neighborhoods, among bits and groups of bits. The so-called “color” appears to play a role in neighborhoods and screening, so it’s not just the equivalent of surface reflectivity. People search for simple equations, simple cellular automata, simple decision trees, that can predict or compress the message. Physicists invent entire new theories of physics that might describe universes projected onto the grid—for it seems quite plausible that a message such as this is being sent from beyond the Matrix. After receiving 32 × 512 × 256 = 4,194,304 bits, around one and a half months, the stars stop flickering. Theoretical work continues.

What if you build your own simulated universe? The classic example of a simulated universe is Conway’s Game of Life. I do urge you to investigate Life if you’ve never played it—it’s important for comprehending the notion of “physical law.” Conway’s Life has been proven Turing-complete, so it would be possible to build a sentient being in the Life universe, although it might be rather fragile and awkward. Other cellular automata would make it simpler. Could you, by creating a simulated universe, escape the reach of God? Could you simulate a Game of Life containing sentient entities, and torture the beings therein? But if God is watching everywhere, then trying to build an unfair Life just results in the God stepping in to modify your computer’s transistors. If the physics you set up in your computer program calls for a sentient Life-entity to be endlessly tortured for no particular reason, the God will intervene.

Yes, as Dawkins says they are creatures naturally evolved in their physical universe and they cannot violate their physics (Dawkins 2006), but they can violate ours if they want. Make this simple experiment: Run a Game of Life program, choose an initial pattern, and let it evolve for a while. Now, stop the program, flip a cell, and resume the program. You have just performed a miracle: something that goes against the physical laws (the simple cellular automata evolution rules of Life) of the lower-level reality that you are simulating. Of course the Game of Life is too simple to contain conscious observers, but hypothetical observers within the game would observe an event that cannot be understood in terms of the physical laws of their universe. A miracle. Berkeley and Moravec are not only saying similar things, they are saying the same thing using different wording.

The system of the world by Neal Stephenson

bank run, British Empire, cellular automata, Edmond Halley, Fellow of the Royal Society, high net worth, Isaac Newton, James Watt: steam engine, joint-stock company, large denomination, MITM: man-in-the-middle, place-making, the market place, trade route, transatlantic slave trade

Many others have, knowingly or not, contributed to a milieu in which it was possible for me to consider writing something like this without seeming completely mad. And here I am tempted to list the names of a lot of mathematicians and physicists. But out of a concern for their privacy and a desire not to seem like I’m clinging to their ankles, I’ll draw a veil over those conversations. Suffice it to say that the Royal Society crowd written about in these books has many descendants and heirs today, who are capable of talking learnedly about monads, cellular automata, the calculus dispute, absolute time and space, &c. at the drop of a hat, and that it’s been my privilege to know a few of them. They seem pleasantly surprised to learn that someone actually wants to write a novel about such topics, and I in turn have been pleasantly surprised to find that they are actually willing to spend time talking to me, and out of this, quite a few good conversations have arisen over the years.
