I.\" *Physical Review B* 4(9), 3174–3183 (1971). DOI: 10.1103/PhysRevB.4.3174.\n\nWilson, K.G. \"Renormalization Group and Critical Phenomena. II.\" *Physical Review B* 4(9), 3184–3205 (1971). DOI: 10.1103/PhysRevB.4.3184.\n\n## The Claim\n\nAt criticality, correlation length shoots to infinity. The system forgets its atoms. Symmetry alone picks the numbers.\n\n## The Context\n\n1971. Cornell. Magnets, fluids, and alloys share the same exponents. Landau's theory fails. Experiments defy prediction. Wilson takes Kadanoff's block-spin idea and builds the machine. Coarse-graining erases the small. The large survives.\n\n## The Evidence\n\nWilson writes the renormalization group as a flow. Repeated rescaling drives the Hamiltonian toward fixed points. At those points, ξ → ∞. Finite scales wash away. Critical exponents emerge as eigenvalues. Part I maps Kadanoff scaling to field theory. Part II runs the phase-space cell analysis. The epsilon expansion debuts. The numbers match experiment.\n\n## The Convergence\n\nThis instantiates **C05 — Criticality** and **C10 — Scale Invariance**.\n\nWilson proves that criticality and scale invariance are one face. No characteristic scale means power laws. The same exponents rule magnets, fluids, and sandpiles. The renormalization group is the bridge. It links Bak's avalanches [SOURCE:bak-1987|type:empirical] to fractal geometry to metabolic scaling. One engine. Many bodies.\n\nGRAIN scores this edge at convergence strength 8. Four fields. Four methods. Same statistics.\n\n## The Honest Limits\n\nWilson addresses equilibrium. He does not touch self-organized criticality. Bak's sandpiles find criticality alone. Wilson needs a dial.\n\nThe epsilon expansion lives near four dimensions. Low dimensions break it. The Kosterlitz-Thouless transition escapes his net.\n\nWilson gives math. He does not give the why. Why do brains, markets, and quakes sit near criticality? That waits for Beggs, Kauffman, and GRAIN.\n\nRival: power laws are fitting artifacts. Log-log plots make them appear. Finite systems show cutoff effects. Pure scaling is an idealization.\n\n## The Receipt\n\n> \"At criticality, correlation length ξ → ∞; the system becomes scale-invariant.\"\n\nThis is Wilson's core payload. The Hamiltonian flows to H* under rescaling. Microscopic details vanish. Different systems land on the same fixed point. Same exponents. Same numbers. That is the proof.\n\n## Related Sources\n\n- [Bak, Tang & Wiesenfeld — Self-Organized Criticality (1987)](/articles/bak-1987): Wilson's math meets systems that tune themselves.\n- [Schrödinger 1944 — What Is Life?](/articles/schrodinger-1944): Physics crosses into biology.
