> ..research at #Kirikongo has revealed a,, socio-political sequence, with the development of institutionalized inequalities over the course of the 1st millennium CE, followed by an egalitarian revolution in the early 2nd millennium CE. The consequent social formation, despite being structurally egalitarian was actually more complex than the vertically oriented system.. and..question common assumptions of #directionality in #SocioPoliticalEvolution.

Will we transform by design or by disaster? In our post for the LSE Impact Blog, @KBBogner, Sophie Urmetzer, and I discuss
#transformativeresearch and how it can help to address issues of
#directionality, #legitimacy, and #responsibility in #transformations, using the example of #just and #sustainable #MobilityTransitions https://blogs.lse.ac.uk/impactofsocialsciences/2023/01/31/transformation-by-design-or-by-disaster-why-we-need-more-transformative-research-now/

Working on my #bot to explore escape-time fractals, rendered with distance estimator colouring using my #et project. It's a #bash script that calls out to #ghc #haskell for calculator functionality, plus image fitness function in custom #C code (using #openmp for #parallel processing).

Flatness of #directionality #histogram seems to be a good #metric to add into the #fitness function for exploring #fractals algorithmically, because stretched/skewed images will have strong directionality peaks, while more #isotropic regions will be flatter.

I implemented it using 5x5 #Sobel filters as suggested on the #ImageJ website. Nothing fancy (like Earth Mover's Distance, which I haven't figured out for circular arrays yet) for the histogram comparison, just Euclidean vector distance.
