Roger - I think you made it up well, and it does apply. I was surprised the first time I discovered that the dendro of neural "branching" derived from tree-structures.
I'm still puzzling over whether Glen has a deeper or more subtle structure than the "mere"interpenetrating branching structures implied say by capillaries, where the in/out flow is exchanged. I am sensing that there is something "special" about the interface between hierarchical flows and diffusion systems? The veins/arteries deliver/remove blood but there is another type of exchange that goes on in between which is more than diffusion which sort of implies homogenous structure? - Steve On 8/18/18 11:15 PM, Roger Critchlow wrote: > I hadn't thought of trees explicitly, I was working the branching > geometries of neural dendrites and crystals.
