Primes¶
- Cascade
- The pattern was first studied quantitatively in physical and biochemical systems — nuclear chain reactions, where each fission liberates neutrons that induce further fissions, and enzymatic signaling chains, where one activated molecule activates many copies of the next — and it was given a general mathematical home in percolation theory and the science of self-organized criticality, where the question becomes whether a local flip dies out or sweeps the lattice.
This sourceDevelops the nuclear fission chain reaction and the effective neutron multiplication factor k as the criticality eigenvalue separating sub-critical decay (k < 1) from super-critical growth (k > 1) — the canonical first-quantified cascade and the prototype of the cross-domain criticality parameter.

Textbook supports the nuclear chain-reaction example, with multiplication factor k, but not the history, enzymatic chains, percolation or self-organized criticality.
“neutrons emitted by fissioning nuclei induce fissions in other fissile or fissionable nuclei; the neutrons from these fissions induce fissions in still other fissile or fissionable nuclei”

- Preparation
- In nuclear physics, subcritical assemblies hold fissile material just below criticality so an inserted source produces fast prompt-critical behavior.
This sourceDefines criticality (k=1), subcritical (k<1) and supercritical assemblies, and the role of a neutron source in initiating a chain reaction.

Lamarsh and Baratta define a subcritical system (k<1) as one whose fissions decline each generation; they do not describe source-driven prompt-critical behaviour.
“if k is less than 1, the number of fissions decreases with time and the chain reaction is called subcritical”
- In nuclear physics, subcritical assemblies hold fissile material just below criticality so an inserted source produces fast prompt-critical behavior.
Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 2 of 2 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
