Asymmetrisk

Asymmetrisk describes the quality of lacking symmetry or balanced correspondence between parts. It contrasts with symmetric, where a transformation can map an object onto itself. The term is used across disciplines to indicate that one side, component, or aspect does not mirror the other.

In geometry, an object is asymmetrical if it has no nontrivial symmetry operations, such as a reflection or rotation that leaves it unchanged. An irregular shape or a scalene triangle typically lacks symmetry. In design and art, asymmetry can create balance without mirror-imaging by varying weight, color, or proportion.

In physics, symmetry principles underpin many laws and conservation rules. When a system does not behave the same under a given transformation, the symmetry is broken. Examples include parity violation in weak interactions and CP violation, which reflect fundamental differences between matter and antimatter. Time asymmetry, or the arrow of time, arises in processes that increase entropy and do not reverse under time reversal.

In biology, organisms often display left–right asymmetry, such as the typical placement of the heart on the left side. Developmental biology studies how genes and signaling pathways establish consistent asymmetries during growth and embryogenesis.

In chemistry, chirality refers to asymmetry at the molecular level, where mirror-image isomers (enantiomers) can have distinct properties, notably in biological activity and aroma.

In information technology and economics, asymmetry denotes uneven distribution of information or capabilities. Asymmetric cryptography uses different keys for encryption and decryption, while information asymmetry can influence market outcomes and decision making.
