# Glossary of Key Terms

 I’m grouping by tier so it’s not just an A–Z dump but a hierarchy that reflects how the system actually stacks:

**Core Principles**

* Perception — The act of observing is not passive. It is a physical process of collapse that resolves possibilities into commitments. Perception begins in the body and extends upward into consciousness.
* Collapse — The transition from possibility to embodied record. Once a signal is registered, it cannot be “un-seen” or “un-felt”; the body has committed.
* Observer — Any system that forces an outcome to exist as a record. In Cultural Physics, humans are observers because perception itself collapses possibility into reality.

#### Probability Space

* Amplitude (Probability Amplitude) — The structured distribution of possible perceptions a signal can collapse into. Amplitudes are not flat probabilities; they carry structure that allows reinforcement, cancellation, or interference.
* Wavefunction (Cultural) — The full set of potential interpretations or responses available before collapse. A meme, phrase, or ritual carries a wavefunction of meanings until it resolves.
* Basis (Measurement Basis) — The context or frame in which a signal is encountered. Different bases (channel, medium, tone, setting) determine which component of the amplitude field is even available to collapse.

#### Field Mechanics

* Resonance — Amplification through alignment. When a signal’s rhythm, tone, or frequency matches the natural frequencies of bodies or environments, energy transfers with minimal loss. Small inputs produce outsized responses.
* Coherence — Stability in the field. The degree to which phase alignment holds over time, allowing signals to reinforce each other consistently and groups to maintain rhythm. Coherence turns resonance into infrastructure.
* Decoherence — Breakdown of alignment. When noise, basis rotation, or environmental coupling destroy shared phase relationships, the field loses stability and collapses into drift or fragmentation.
* Q-Factor (Cultural) — The “sharpness” of resonance in a field. High-Q = narrow, selective, amplifying; low-Q = broad, permissive, flatter. Determines whether coherence is brittle or adaptive.

#### Embodied Substrate

* Somatic Marker — Bodily signal (gut feeling, physiological shift) that precedes conscious awareness, guiding perception before thought.
* Neuroception — Continuous, below-awareness scanning by the autonomic nervous system for cues of safety, danger, or life threat.
* Distributed Intelligence — The body as a network of minds: gut brain, heart brain, cranial brain, each processing and sending signals. Intelligence is not localized but spread across tissues.
* Electromagnetic Field (Cultural) — The measurable bioelectric fields generated by bodies (especially the heart). These fields entrain nearby nervous systems, producing shared states that feel like “vibe” or “energy.”

**Cultural Infrastructure**

* Membrane — The boundary of a cultural field. Not a hard border, but a semi-permeable atmosphere that holds rhythm and makes recognition possible.
* Tradition — Repetition of action that stabilizes values over time. Ritualized coherence.
* Value — The center of cultural meaning. What a group consistently protects, repeats, and orients around.
* Drift — Loss of coherence that leads to cultural weakening or fragmentation. Can follow unresolved elevation, noise, or membrane rupture.

### Applied Mechanics (for system use)

* Heartstream — Collective entrainment of bodies into shared physiological rhythm (heartbeat, breath, attention). A marker of coherence at scale
* Somatic Ratio Conversion (SRC) — The weighting of body-first vs cognitive signals in perception. Under pressure, somatic cues dominate collapse.
* Signal Pathway Matrix (SPM) — The mapping of how signals travel across bodies, narratives, and institutions, showing points of reinforcement, distortion, or loss.
* Nodes — Charged sites of cultural memory or meaning that store amplitude histories and can be re-evoked with minimal input.
* Gates — Threshold points that control the basis of measurement (ritual openings, institutional processes, platform affordances). Gates determine how signals collapse by sequencing exposure.
