chain reaction
Let an agent explain chain reactions across chemistry, physics and biology, relay mechanisms and examples from reference sources at a public level, describe chain reactions in living organisms, and distinguish chain reactions from single-step reactions, from domino effects in everyday usage and from the polymerase chain reaction as a named technique, without operational nuclear detail.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain chain reactions across chemistry, physics and biology, relay mechanisms and examples from reference sources at a public level, describe chain reactions in living organisms, and distinguish chain reactions from single-step reactions, from domino effects in everyday usage and from the polymerase chain reaction as a named technique, without operational nuclear detail.
A sequence of reactions in which a reactive product or by-product causes further reactions, so the process can become self-sustaining, as in chemical chain reactions involving radicals in combustion and polymerisation, nuclear chain reactions in which neutrons from fission cause further fissions in reactors, and chain-like cascades in living organisms such as lipid peroxidation and the polymerase chain reaction as a laboratory method; the model describes nuclear chain reactions at a public reference level only.
What it is for: Not applicable; a type of process.
It can be explain mechanisms; relay examples across fields; describe biological cases; distinguish related concepts.
Distinguishing features
Self-propagating
Initiation and termination
Chemical and nuclear
Biological cascades
What it looks like
Not a visible object; a cascade of reactions.
Physical character
chain steps: initiation, propagation, termination list - chemical
first controlled nuclear chain reaction: 1942 year - Chicago Pile-1
Bodenstein chain reaction concept: 1913 year
How it is recognised
Reactions propagated by their own products
Radical chain reactions, nuclear chain reactions, chain reactions in living organisms
Single-step reactions do not propagate; everyday domino effects are metaphorical; PCR is a named laboratory technique
