Study Finds Similar Structures In the Universe, Internet, and Brain

SternisheFan writes "The structure of the universe and the laws that govern its growth may be more similar than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people, according to a new study. 'By no means do we claim that the universe is a global brain or a computer,' said Dmitri Krioukov, co-author of the paper, published by the Cooperative Association for Internet Data Analysis (CAIDA), based at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego.'But the discovered equivalence between the growth of the universe and complex networks strongly suggests that unexpectedly similar laws govern the dynamics of these very different complex systems,' Krioukov noted."

    I have learned after studying many differing fields of science and engineering, that as you master one field you gain insight into many others. There are certain patterns of organization that repeat throughout nature, and mimicked by man, and if you study anything long enough you are certain to see these patterns. The more you learn, the easier it becomes to learn more because natural things are mostly variations on a finite set of themes that, whether you are aware of them or not, you will discover them and from that point forward, notice them much more quickly.

    This is one example. There are many more.

Since an interpreter is realized-by and realized computations, according to the Church-Turing thesis an equivalent lambda calculus problem exists.

This is not because somebody "made up" mathematics and "chose" it to provide tools for analyzing the physical world as physics. It was because it worked. It was not a choice of "convenience".

      I know it is difficult for someone who has never studied theoretical physics to get that mathematics is so fundamentally profound for any useful understanding of reality. One way of looking at quantum mechanics is to think of it as an attempt to build a mathematical representation of the basic kinds of physical interactions, those occurring on the Plank scale. The results of quantum mechanics seem bizarre and could never have been arrived at without mathematics. We have a poor physical intuition for what is going on at those scales, it's beyond our experience.

      All most people have is painful memories of years of suffering math (mainly just elementary algebra and simple calculus) in a high school classroom. I hated those and this created years of math phobia that I had to work hard to consciously beat.

The beauty then shines through, for me it was once I could see the towering intellectual mountain of theoretical physics.

      It turns on the definition of complexity itself, which is not so straightforward as one might imagine. One of the keys to many definitions of complexity lies not in the number of different parts, but in the non-trivial and adaptive ways those parts interact. Yes, there may be humans in this galaxy, but the relationships between those humans have no effect on the galaxy, qua galaxy. In other words, the interactions that occur on a galactic level produce no appreciable feedback in the system as a whole from human beings. Yet it is feedback and adaptation that occurs in complex systems that make them complex. As a complex system, therefore, the galaxy is not concerned with the presence of humans.

      The same cannot be said of the relationship between neurons as a system and the brain as a system. As the article says, each neuron has its own level of complexity and this is in turn connected to the larger system of the brain, itself having billions of adaptive connections. Yet what is missing, but I think implied, is that the complexity within each neuron is non-trivial to the interactions between neurons.

For those interested in but unfamiliar with these matters, I recommend a volume written a couple of years ago by the physicist Albert-László Barabási called Linked: The New Science of Networks . It is written for a wide audience and is a very readable introduction to the subject. Barabási's based argument is that these common network patterns we see in so many environments is a consequence both growth and preferential attachment in systems. Of course, growth and preferential attachment are going to be present in biological and social systems, as well as things like computer networks, and this is at the heart of why we see similar patterns forming (esp. scale-free topologies).

    As a historian, I find the findings of network science as its been applied to social systems particularly useful. It helps to explain societal changes in ways that older theories of history, whether deriving from Marxian, Annaliste, Weberian, or other schools of thought, would have difficulty. Further, the study of networks and complex systems is inherently interdisciplinary--and this in a refreshingly honest way rather than the mere "interdisciplinarity" rhetoric that's been present in the academy over the years.

Unlike random distributions, scale-free topologies are highly resistant to random failure: i.e. random deaths of animals of different sorts do not cause an ecosystem failure or random power stations failing does not necessarily cause a grid to collapse. This is what network and complex systems theorists call robustness. Scale-free topologies are, however, very vulnerable to directed attacks. Turns out certain creatures occupy more important spaces in ecosystems than others (they're hubs, with a high density of connections). Kill these off and an entire ecosystem can collapse.
