Eridi

Eridi is a term used in the fictional field of sociotechnical systems to denote a unit of network coherence. In the speculative framework, an eridi measures the integrated capacity of a system to coordinate information, actions, and responses across its components. One eridi is defined as the baseline level of coherence observed in an idealized triad of interacting nodes under steady-state conditions; more complex networks yield eridi values scaled by topology, connectivity, and load.

Etymology: The word is drawn from the imagined Eridanic language in the universe where the concept originated; eri- meaning connect and -di a nominal suffix for unit.

Usage: Researchers compute eridi by aggregating normalized indicators such as information throughput, latency, fault tolerance, and cross-node synchronization. An eridi is context-dependent; it has no fixed numeric value across all systems, and comparisons require a common reference topology and load.

Variants: Some authors discuss eridi points, eridi index, or eridi density as alternative descriptors that emphasize intensity, quality, or spatial distribution of coherence.

History: The concept emerged in worldbuilding literature and theoretical discourse in the 22nd to 23rd centuries within the fictional Eridan Institute. It has since circulated in speculative papers and educational media to illustrate concepts of emergent coordination in networks.

Criticism: Critics argue that eridi blends qualitative and quantitative aspects and can be sensitive to measurement choices and network structure, limiting cross-study comparability.
