## 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. Iâ€™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 realtionship 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?

Can we represent this as a network (or a landscape?) that accretes around agent activity? Some kind of growth process? (keywords: â€śmodels of growth aggregationâ€ť, â€śrough interfacesâ€ť, â€śgrowth with surface diffusionâ€ť, â€śnucleationâ€ť, â€śmorphogenesisâ€ť) 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 GĂ¶del 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?
