Part III: Regulatory Dynamics
"Regulation is ψ maintaining itself—feedback loops within feedback loops, creating stability from flux, order from chaos, life from entropy's edge."
Overview
Part III explores how molecular interactions create regulatory systems that maintain cellular homeostasis through ψ = ψ(ψ). These 16 chapters reveal how cells sense their state, make decisions, and coordinate responses through dynamic regulatory networks.

Reading Approach
Begin with stress response systems (Chapters 33-36), progress through cell cycle regulation (Chapters 37-40), then explore intercellular communication (Chapters 41-48).
"In regulatory dynamics, ψ achieves the impossible—maintaining identity while constantly changing, creating stability from perpetual flux through the magic of recursive control."
