Stuart Hameroff: Penrose's Quantum Consciousness Theory Explained

Stuart Hameroff discusses his quantum microtubule theory of consciousness with Roger Penrose, exploring self‑similarity, Gödel’s theorem, and the hard problem. The conversation also tackles free will, quantum computing, and the relationship between cognition and consciousness.
