I am not qualified to have an opinion about Wolfram's A New Kind of Science. I've read it 1.75 times just to confirm this fact. I can't evaluate the claims about how much of what he says is new, but I also sort of don't care, except in a gossip-y sort of way. So why am I interested? First, since I was in high school I've been bothered by the notion of laws. It's a metaphor that scientists immediately reject: there's no governing body, there's no jail time for miscreants. So, then it's just regularities and correlations. But that's not much of an explanation. Wolfram tries to explain phenomena by asking what's the simplest computer program that could have generated it. I don't know that that is any more of an explanation, but it's at least a radically different type of explanation. One indication of its radicalness: some phenomena cannot be predicted by solving an equation but only by running the program. I like the fact that his approach holds hope (but I can't evaluate how much) for understanding complex phenomena. Traditional science often punks out there. I asked a physicist friend of mine about this, a guy who was in grad school with Wolfram btw, and he said that the structure of heavy atoms is too complex to be managed — so far — by our equations. So, here's exactly the sort of problem that Kuhn pointed to, a limit against which the current paradigm bumps. And it's not in some marginal area. Complexity is clearly hugely important, from snowflakes to brains to galaxies. Wolfram may have (I can't tell) made progress in understanding how complexity can be generated from very simple rules. I'm also interested in watching the scientific community's reaction to it. Will it embrace or reject (or take a third path) this? Likewise, will there be sufficient application of Wolfram's ideas to recalcitrant existing problems to establish it as a workable paradigm? Fascinating. And I'm very interested in his metaphysics because it seems to be the apotheosis of a modern trend: the triumph of formalism. The discussion in the comments section of my blog recently about Kurzweil and Searle typifies the deep division in our thought. Many of us find it obvious that the brain is hardware running software, and thus we will be able to move the software into another medium and run it losslessly, just like we can move our copy Sim City and our saved games from one computer to another. But this seems to me to be so fundamentally wrong, for reasons I won't discuss again here. Wolfram takes the brain-as-software idea to its ultimate extension: the universe is software. His books attempts to derive space, time and the fundamental particles of physics from purely formal considerations. Wow. He's also an excellent writer and a truly interesting character. I've had the opportunity to spend a little time with him, and I like him. Although I'm frustrated by my inability to follow his argument past page 500 or so, I also think there's a certain benefit to being forced into agnosticism about his content, for the questions that circle "Is he right?" are fascinating on their own.

Whether you have time to wade through it or even if you can find a volume since I believe it is out of print, you might want to compare Bucky Fuller's Synergetics to this idea of models vs equations.
In Bucky's 4-dimensional (always time too) geometric approach, the large-scale structures are not the subject of the model, but the small-scale structures which add up to and become the larger system. For example, there's nothing about a caterpillar that suggests a butterfly unless you build a model that starts from the genetic strands or even before, perhaps down to the quark or sub-quark (Bucky's A and B modules) and then approach this minimum geometry along the bindings (edge or point), flexing, recombining and accruing additional primative structures, building up through organic growth.
Thus the hairline precision structural component dimensions in a geodesic dome are a bitch to compute, yet we all know nature has no trouble at all constructing an extremely high-frequency geodesic orange peel.
Put another way, Bucky asks,

You might enjoy a famous quote by a famous formalist on the foundations of the purest formalism of them all, mathematics:
As quoted from J.Dieudonné, 1970, "The work of Nicholas Bourbaki", American Mathematical Monthly, 77, 134-145.
Som context: Nicholas Bourbaki was the nom de plume of an influential group of french mathematicans (Dieudonne being one of them) who in a series of text books erected the 'new math' a formidable reworking of all of mathematics from strict formal principles.

You write eloquently about these issues! I know you wrote this entry nearly a year ago. I hope to give a talk at the 2nd NKS conference about how people are responding to fundamental physics ideas of NKS in internet forums, blogs, etc. If you have ideas of what to include in the talk, I would be grateful. Also, you may be interested in my own blog; the entries of most relevance to NKS are cataloged under "philosophy" on my home page.

How does NKS and Walter Russell's "The Universal One" compare with your philosophy and Science? Are you familiar with The writings dating back to 1926 of Walter Russell? his books are available from www.philosophy.org I hope you email me back an answer.SP
