At the deepest level, Wolfram argues that—like many of the most important scientific ideas—the principle of computational equivalence allows science to be more general by pointing out new ways in which humans are not "special"; that is, it has been claimed that the complexity of human intelligence makes us special, but the Principle asserts otherwise.
In a sense, many of Wolfram's ideas are based on understanding the scientific process—including the human mind—as operating within the same universe it studies, rather than being outside it. There are a number of specific results and ideas in the NKS book, and they can be organized into several themes.
One common theme of examples and applications is demonstrating how little complexity it takes to achieve interesting behavior, and how the proper methodology can discover this behavior. First, there are several cases where the NKS book introduces what was, during the book's composition, the simplest known system in some class that has a particular characteristic.
Some examples include the first primitive recursive function that results in complexity, the smallest universal Turing Machine , and the shortest axiom for propositional calculus. In a similar vein, Wolfram also demonstrates many simple programs that exhibit phenomena like phase transitions , conserved quantities , continuum behavior, and thermodynamics that are familiar from traditional science. Simple computational models of natural systems like shell growth , fluid turbulence , and phyllotaxis are a final category of applications that fall in this theme.
Another common theme is taking facts about the computational universe as a whole and using them to reason about fields in a holistic way. For instance, Wolfram discusses how facts about the computational universe inform evolutionary theory , SETI , free will , computational complexity theory , and philosophical fields like ontology , epistemology , and even postmodernism.
Wolfram suggests that the theory of computational irreducibility may provide a resolution to the existence of free will in a nominally deterministic universe. He posits that the computational process in the brain of the being with free will is actually complex enough so that it cannot be captured in a simpler computation, due to the principle of computational irreducibility.
Thus, while the process is indeed deterministic, there is no better way to determine the being's will than, in essence, to run the experiment and let the being exercise it. The book also contains a vast number of individual results—both experimental and analytic—about what a particular automaton computes, or what its characteristics are, using some methods of analysis.
The book contains a new technical result in describing the Turing completeness of the Rule cellular automaton. Very small Turing machines can simulate Rule , which Wolfram demonstrates using a 2-state 5-symbol universal Turing machine. Wolfram conjectures that a particular 2-state 3-symbol Turing machine is universal. Every year, Wolfram and his group of instructors  organize a summer school. In , the program was held at Curry College in Milton, Massachusetts. After 14 consecutive summer schools, more than people have participated, some of whom continued developing their 3-week research projects as their Master's or Ph.
D theses. Others found that the work contained valuable insights and refreshing ideas. A tenet of NKS is that the simpler the system, the more likely a version of it will recur in a wide variety of more complicated contexts. Therefore, NKS argues that systematically exploring the space of simple programs will lead to a base of reusable knowledge.
However, many scientists believe that of all possible parameters, only some actually occur in the universe. For instance, of all possible permutations of the symbols making up an equation, most will be essentially meaningless. NKS has also been criticized for asserting that the behavior of simple systems is somehow representative of all systems.
A common criticism of NKS is that it does not follow established scientific methodology. For instance, NKS does not establish rigorous mathematical definitions,  nor does it attempt to prove theorems ; and most formulas and equations are written in Mathematica rather than standard notation.
NKS has been criticized for not providing specific results that would be immediately applicable to ongoing scientific research. Steven Weinberg has pointed out that no real world system has been explained using Wolfram's methods in a satisfactory fashion. The Principle of computational equivalence PCE has been criticized for being vague, unmathematical, and for not making directly verifiable predictions. Wolfram's speculations of a direction towards a fundamental theory of physics have been criticized as vague and obsolete.
Scott Aaronson , Professor of Computer Science at University of Texas Austin, also claims that Wolfram's methods cannot be compatible with both special relativity and Bell's theorem violations, and hence cannot explain the observed results of Bell test experiments. Edward Fredkin and Konrad Zuse pioneered the idea of a computable universe , the former by writing a line in his book on how the world might be like a cellular automaton, and later further developed by Fredkin using a toy model called Salt.
In a review of NKS , the Nobel laureate and elementary particle physicist Steven Weinberg wrote, "Wolfram himself is a lapsed elementary particle physicist, and I suppose he can't resist trying to apply his experience with digital computer programs to the laws of nature. This has led him to the view also considered in a paper by Richard Feynman that nature is discrete rather than continuous. He suggests that space consists of a set of isolated points, like cells in a cellular automaton, and that even time flows in discrete steps.

Pinging is currently not allowed. John Smith says:. May 17, at pm. Tony H. May 20, at pm. Forrest Richey says:. April 15, at am. Want to automatically make an interesting custom piece of art? Just start looking at simple programs and automatically pick out one you like —as in our WolframTones music site from a decade ago.
Want to find an optimal algorithm for something? Well, then just enumerate cellular automata as I did in , and very quickly you come upon rule 30—which turns out to be one of the very best known generators of apparent randomness look down the center column of cell values, for examples.
In other situations you might have to search , cases as I did in finding the simplest axiom system for logic , or the simplest universal Turing machine , or you might have to search millions or even trillions of cases. One finds some tiny program out in the computational universe. One can tell it does what one wants.
We may notice that some particular substance is a useful drug or a great chemical catalyst, but we may have no idea why. But in doing engineering and in most of our modern efforts to build technology, the great emphasis has instead been on constructing things whose design and operation we can readily understand. In the past we might have thought that was enough. What will the world look like when more of what we have is mined from the computational universe?
Today the environment we build for ourselves is dominated by things like simple shapes and repetitive processes. But sometimes they may look quite random, until perhaps suddenly and incomprehensibly they achieve something we recognize. For several millennia we as a civilization have been on a path to understand more about what happens in our world—whether by using science to decode nature, or by creating our own environment through technology. But to use more of the richness of the computational universe we must at least to some extent forsake this path.
We ourselves, as biological systems, are a great example of computation happening at a molecular scale—and we are no doubt rife with computational irreducibility which is, at some fundamental level, why medicine is hard. I was fortunate enough that my own very first field—particle physics—was in its period of hypergrowth right when I was involved in the late s. But today, the obvious field in hypergrowth is machine learning , or, more specifically, neural nets.
I actually worked on neural nets back in , before I started on cellular automata, and several years before I found rule But I never managed to get neural nets to do anything very interesting—and actually I found them too messy and complicated for the fundamental questions I was concerned with. I was also inspired by things like the Ising model in statistical physics, etc. At the outset , I thought I might have simplified too far, and that my little cellular automata would never do anything interesting.
But then I found things like rule But about 5 years ago I suddenly started hearing amazing things: that somehow the idea of training neural nets to do sophisticated things was actually working. But then we started building neural net capabilities in the Wolfram Language, and finally two years ago we released our ImageIdentify.
There are lots of tasks that had traditionally been viewed as the unique domain of humans, but which now we can routinely do by computer. A neural net is really a sequence of functions that operate on arrays of numbers, with each function typically taking quite a few inputs from around the array. And instead of taking inputs from all over the place, in a cellular automaton each step takes inputs only from a very well-defined local region.
Because it shows that out in the computational universe, away from the constraints of explicitly building systems whose detailed behavior one can foresee, there are immediately all sorts of rich and useful things to be found. Is there a way to bring the full power of the computational universe—and the ideas of A New Kind of Science —to the kinds of things one does with neural nets?
I suspect so. And perhaps even it will be possible to invent some major generalization of things like calculus that will operate in the full computational universe. I have some suspicions, based on thinking about generalizing basic notions of geometry to cover things like cellular automaton rule spaces.
What would this let one do? Likely it would let one find considerably simpler systems that could achieve particular computational goals. Because they imply that even neural nets of the kinds we have now are universal, and are capable of emulating anything any other system can do.
In fact, this universality result was essentially what launched the whole modern idea of neural nets , back in But my guess is that there are tasks where for the foreseeable future access to the full computational universe will be necessary to make them even vaguely practical.
What will it take to make artificial intelligence? As a kid, I was very interested in figuring out how to make a computer know things, and be able to answer questions from what it knew. And when I studied neural nets in , it was partly in the context of trying to understand how to build such a system. I returned to the problem every so often, and kept putting it off. And it was this realization that got me started building Wolfram Alpha. But definition is a more difficult and central issue than we might imagine.
As powerful as anything that happens in our brains. It sounds so animistic and pre-scientific. Life , intelligence , consciousness: they are all concepts that we have a specific example of, here on Earth.
But what are they in general? All life on Earth shares RNA and the structure of cell membranes. And so it is with intelligence. But human intelligence as we experience it is deeply entangled with human civilization, human culture and ultimately also human physiology—even though none of these details are presumably relevant in the abstract definition of intelligence.
We might think about extraterrestrial intelligence. We imagine that in doing the things we humans do, we operate with certain goals or purposes. After all, there are definite laws of nature that govern our brains. So anything we do is at some level just playing out those laws. And this is crucial in thinking about AI.
We know we can have computational systems whose operations are as sophisticated as anything. But can we get them to do things that are aligned with human goals and purposes? Now what I more see myself as doing is making a bridge between our patterns of human thinking, and what the computational universe is capable of.
There are all sorts of amazing things that can in principle be done by computation. But what the language does is to provide a way for us humans to express what we want done, or want to achieve—and then to get this actually executed, as automatically as possible. Language design has to start from what we know and are familiar with. In the Wolfram Language, we name the built-in primitives with English words, leveraging the meanings that those words have acquired.
But the Wolfram Language is not like natural language. But it gives us a way to build up arbitrarily sophisticated programs that in effect express arbitrarily complex goals. Yes, the computational universe is capable of remarkable things. But in building the Wolfram Language my goal is to do the best I can in capturing everything we humans want—and being able to express it in executable computational terms.See more about this book on Archive.
