Convergence Edge 4: Criticality ↔ Scale Invariance
C05 (Criticality) recurs-with C10 (Scale Invariance)
Shared pattern: Power-law statistics; no characteristic scale; self-similarity across magnitudes; universality of exponents
Domain distance: Condensed matter physics → Biology → Urban science (large)
Derivation independence: HIGH. Bak (physics, Brookhaven, 1987) derived SOC from sandpile models. Wilson (physics, Cornell, 1971) derived universality from renormalization group. Mandelbrot (mathematics, IBM, 1982) derived fractals from noise analysis. WBE (biology, Santa Fe, 1997) derived allometric scaling from transport networks. Four fields, four methods, same statistics.
Convergence strength (1–10): 8
Note: The edge captures that criticality and scale invariance are two faces of the same phenomenon — no characteristic scale means events of all sizes, which means power laws.
