Knowledge geometry

  • Innovation Is a material basis for technology plus a knowledge topology equal to a model of technology? I suspect not - surely there are emergent effects. But there must be a relationship.
  • Spaces of strings
  • String dynamics

Related question: What is the shape of the vocabulary of communicating people? When do we denote new things?

What is the shape of collected human knowledge?

This is vague. I do not have the rigorous definitions to even post the question here, but let me spitball a few ideas about how branches of knowledge might be adjacent to each other ot not. I’m thinking of hyperbolic and other non-euclidean geometries and wondering about how you can project the articles of an encyclopaedia onto them, preserving some notice of similarity, dependency or priority.

But then, because our monkey minds work this way, we seem to project them onto maps:

What kind of knowledge relationship mechanisms are plausible? Could you mine patent networks or theorem networks to parameterise a stochastic process for this model which made it a plausible model for theorem growth? If not, what quality does knowledge posses which this could not encapsulate?

Franka Miriam Brückler’s famous map of Middle Math

Can we represent this as a network (or a landscape?) that accretes around agent activity? Some kind of growth process? (keywords: “models of growth aggregation”, “rough interfaces”, “growth with surface diffusion”, “nucleation”, “morphogenesis”) Is this a constrained growth problem, like the one that governs coral drills?

Investigate configuration spaces of technologies. (See configuration space of the economy.) Genotype-phenotype interactions as a model of knowledge-economic systems? What is the most basic stochastic process that would serve as a model of these?

(Practical aside: How much area must a new thesis carve out from the unmade world?)

Now, going out on a limb, consider a problem domain that looks evolutionary if you squint at it: creating mathematical theorems. Certainly Gödel and Turing invite looking at the things as symbol strings. I saw a presentation (Leibon and Rockmore 2013) suggesting that there was a natural embedding of mathematical field onto hyperbolic geometry. Sure, his data set was Wikipedia mathematical article links, and the whole idea was tongue-in-cheek. But it feels like there is something in there, if not a whole-cloth topological theory of human knowledge. Is there some process driving mathematical innovation that means that the links between fields sit so naturally in hyperbolic space? Is it some characteristic of the subject matter itself? If either of these are true, would they be true of other fields? Science in general? Philosophy? Engineering? Design? Biological fitnesses?
