The growth Péclet number Pe = VR/2D that controls dendritic solidification maps directly onto the Void Framework's Pe parameter through (anisotropy, undercooling, surface tension) → (O, R, α). The KKL solvability condition σ* ∝ ε₄^ (7/4) is spectral eigenvalue selection on a geometric lattice. Diana's Tree (Arbor Dianae) — silver dendrites grown from mercury amalgam in silver nitrate — is the earliest recorded observation of Pe-controlled morphogenesis, predating Ivantsov's 1947 formalization by three centuries.
Anthony W. Eckert (Sat,) studied this question.
