# From Radiation Field to Social Field **Entity class:** Structural-homology map ## Definition **From Radiation Field to Social Field** maps a transferable mathematical architecture while keeping physical radiation and social influence ontologically distinct. | Physical transport | Social/network analogue | | --- | --- | | radiation source | ideological source, recruiter, propaganda channel, or initiating event | | heterogeneous matter and geometry | heterogeneous social graph, platform structure, barriers, and countervailing relationships | | particle transport | information and influence transmission | | flux or field intensity | exposure intensity or frequency | | accumulated dose | cumulative exposure and reinforcement, only as a loose analogue | | biological or system receptor | individual or cohort | | shielding and response functions | network barriers, protective relationships, and heterogeneous susceptibility | | detector measurements | observable communications, encounters, or behavioral indicators | | inverse transport | reconstructing latent sources or network conditions from incomplete observations | | model reduction | compressing a vast graph into variables or local subnetworks that dominate a forecast | | uncertainty quantification | preserving competing hypotheses, provenance, and confidence | ## Evidence Boundary This is a **structural analogy and transferable mathematical architecture**. It is not evidence that Oden, DTRA, or the cited nuclear project made these substitutions. Oden's documented bridge is to epidemic modeling; radicalization research independently documents the social-network and complex-contagion side. ## Relationships - **general architecture:** [[wiki/Transport as a General Predictive Architecture|Transport as a General Predictive Architecture]]. - **physical side:** [[wiki/Radiation Transport Field|Radiation Transport Field]] and [[wiki/Receptor Layer|Receptor Layer]]. - **social side:** [[wiki/Ideological Transmission as Complex Contagion|Ideological Transmission as Complex Contagion]] and [[wiki/Counterterrorism Predictive Graph|Counterterrorism Predictive Graph]]. - **scale:** [[wiki/Theater-to-Person Scale|Theater-to-Person Scale]]. ## Sources / Provenance - [[research/Oden Institute - Theater-to-Person Predictive Scale|Oden Institute: From Theater-Scale Fields to Person-Scale Receptors]]
