I had a coworker who was kind of obsessed with Christopher Langan's supposed "theory of everything," and one article of evidence he introduced was his thought that the way our eyes are circular and they cross their information to produce our three-dimensional vision, was somehow a biological manifestation of a Venn diagram for two circles. I don't know if this came from Langan's writings, but anyway, I did later note that for n = 11, it seems like there is a Venn diagram that looks similar to our eyes-with-cones, viz. the third sample in the following image (from Wolfram):
Another survey (from The Electronic Journal of Combinatorics) extracts the following from the n = 11 case:
Maybe it's my schizophrenia-spectrum problems causing it, but to me this looks similar to the folding of the brain.
So now, as far as I know, if the original premise was derived from Langan, I think he had a Venn diagram at the "center of reality" (so to speak) where three Venn spheres are in play (for his ultimate "triality"). I don't want to ask this question in the spirit of implicitly defending the claims of an arrogant, prejudiced analyst, yet I don't want to say that this guy is "just wrong about everything" or whatever, either. So at least without leading into some majestic and religious doctrine of three Venn spheres encoding the rest of reality by their "interaction," is it possible to interpret at least brains and their accoutrements as Venn-diagramatic in some physical embedded manner?
