Our editorial aim
We aim to explain a concept accurately and in context: what it means, how it works, where it is used and where an explanation stops being applicable.
Research and evidence
Articles should link to the sources supporting their substantive claims. Primary technical documentation, standards, research and official publications are preferred when they address the question. Source quality and relevance matter more than the number of references.
AI assistance
AI tools may assist with research organisation, drafting and illustrations. AI output is not evidence. Claims, references and any calculations require checking before publication.
Scope and limitations
This is general explanatory material. A definition or mechanism alone is not a purchasing recommendation, professional opinion or site-specific operating instruction. Safety-sensitive work requires appropriate expertise.
Updates and corrections
Changes to a substantive explanation should be reflected in its update information. If you identify a problem, use our corrections process. We do not imply professional review unless a real reviewer and review scope are identified on the article.
