Regarding systems at the #EdgeOfChaos
Identifying #PhaseTransition dynamics
Citing @WagnerEvolution on #Robustness
Contrasting it with #Chaos (fragile, hard to predict, etc.)
And then #Criticality, somewhere in the middle... ImageImageImageImage
With #criticality, due to #PowerLaw(-like) distributions:

"Most of the changes will be small, but for some, you can have large changes."

"Fabricating #Clay: #Machines, #Materials, & #Code"

🧵 Today's SFI Seminar by @leahbuechley (@UNM):
"We build the geometry directly by thinking about the PATH that our 3D printer takes. There's no intermediate slicing software [to render CAD as "2D" layers]."

- @leahbuechley, #3DPrinting clay with a 1.5 mm nozzle
"You can start to think about surface textures - like spikes that you can't do with a traditional slicer. Or...here's a path that's a sine wave, but every other layer is rotated. Or...one creature is following THIS path, and the other is chasing it around."

"Argument-Making in the Wild"

Today's SFI Seminar by Simon DeDeo (@LaboratoryMinds), streaming now. Follow our thread for pull quotes and slides:

First, let's divide human history into three eras, or regimes of #knowledge #production and #consumption:

• #premodern/#archaic
• #modern + #postmodern
• the #egregore (online content sharing)

• The premodern era is defined by caloric restriction.
• The modern era is characterized by a small number of sellers of #information vs. a large number of consumers (see also #HerbertSimon's remarks on the "poverty of #attention")
