orthogonality
This term originates from geometry but extends into abstract systems to describe a state of total independence. In a physical sense, it evokes the rigid, clean intersection of a right angle, suggesting a lack of overlap or interference between two directions.
In technical fields like statistics and software engineering, the word shifts from a visual image to a conceptual one. It describes a design where changing one component has no effect on another, creating a modular environment that prevents cascading errors or confounding data.
Meanings
The property of being mutually perpendicular or at right angles to each other.
The orthogonality of the two walls ensures the corner is perfectly square.
The state of being statistically independent or uncorrelated, where one variable does not provide information about another.
The researchers tested the orthogonality of the experimental factors to avoid confounding variables.
In computer science and software design, the property where a small set of primitive operations can be combined in a limited number of ways to build complex structures without unexpected side effects.
The orthogonality of the instruction set allows programmers to combine operations flexibly.
