Chirality
Difference in shape from a mirror image

Chirality is the property of an object not being identical to its reflection, or mirror image. An object is chiral if it is not identical to its reflection; that is, it cannot be superposed onto itself. Conversely, an object is achiral if its reflection cannot be distinguished from the object, such as a sphere.
Begin with the source’s own compact description: “Chirality” is difference in shape from a mirror image. The dossier treats that line as a proposition to test through Chirality, Difference and shape, not as a finished interpretation.
Why this record matters
The phrase “difference in shape from a mirror image” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 30, 2026.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
