String theory confirmed? ;)

  jury still out on string theory and supergravity. that being said… julian casablancas confirmed.

does anyone have an ELI5 on this?

> They found that groups of neurons connect into 'cliques', and that the number of neurons in a clique would lead to its size as a high-dimensional geometric object. So cliques of 11 neurons have been found in the brain? I'd hardly call this 11 dimensional.

  Does that mean this "4D chess" I keep hearing about is just playing chess with a clique of four neurons?

I am guessing that they can't actually mean 11 spacial dimensions. Are they saying something analogous to multi-dimensional data structures? Like these things exist in 3D space but they are akin to arrays of arrays?

  I wonder if it's more like 11 "dimensional analysis" dimensions, rather than space/time+ dimensions. So thinking about something complicated could mean we can process/hold 11 separate variables at a time?

    Maybe they're counting "herbs and spices" as dimensions.
