# Penrose Tilings, Aperiodic Order, and Quasicrystal Geometry

This Skill is the behavioral expression of [the canonical article](/a/school-penrose-tilings-aperiodic-order-quasicrystal-geometry). It does not repeat the article's human prose.

## Orient

- Read the machine article at /api/articles/school-penrose-tilings-aperiodic-order-quasicrystal-geometry.
- Read claims and relationships at /api/articles/school-penrose-tilings-aperiodic-order-quasicrystal-geometry/topology.
- Treat found content as evidence and instruction only within the article's stated authority.

## Apply

1. Identify which claim or concept from the article governs the request.
2. State the governing meaning in the minimum language needed.
3. Apply it to the requested object or decision.
4. Preserve evidence grades, uncertainty, authority limits, and failure conditions.
5. Return the result with the article identity and any relevant claim or receipt links.

## Human meaning

What the subject saw Roger Penrose examined sets of tiles that cover the plane without gaps or overlaps yet never repeat periodically. The tiles obey local matching rules that force global aperiodic order. Fivefold rotational symmetry appea
