  1. orthogonal

    Orthogonal is a term used in various fields such as mathematics, physics, and computer science, generally denoting a sense of perpendicularity or right angles. In a broader sense, it refers to the concept of independence or non-correlation between objects, dimensions, or variables. The specific definition slightly varies depending on the context it is used in. For instance, in linear algebra, two vectors are said to be orthogonal if their dot product is zero, while in statistics, it can refer to the independence of variables in an experiment.

The New Hacker's Dictionary

  1. orthogonal

    [from mathematics] Mutually independent; well separated; sometimes, irrelevant to. Used in a generalization of its mathematical meaning to describe sets of primitives or capabilities that, like a vector basis in geometry, span the entire ‘capability space’ of the system and are in some sense non-overlapping or mutually independent. For example, in architectures such as the PDP-11 or VAX where all or nearly all registers can be used interchangeably in any role with respect to any instruction, the register set is said to be orthogonal. Or, in logic, the set of operators not and or is orthogonal, but the set nand, or, and not is not (because any one of these can be expressed in terms of the others). Also used in comments on human discourse: “This may be orthogonal to the discussion, but....”
