The Phi System
Definition
Andrei's cross-domain framework that uses φ (the golden ratio) as the single proportion connecting his neuroscience research, his identity / brand grid, and his decision-making heuristics.
Why it matters
Domain experts often have one elegant model per field. The Phi System is the bet that, for Andrei's specific stack — Coherence neuroscience, ventures, contemplative practice — One proportion captures something real across all three. It is also the spine of the visual identity used across the site.
Example
The brand grid, the chapter structure of Prisoner of the Mind, and the EEG result all reduce to relationships of the form a : b ≈ b : (a + b).
