ryz

rYZ is a notation used in mathematics, physics, and popular culture to denote a quantity that depends on the Y and Z coordinates or dimensions. The exact meaning of rYZ depends on the context in which it appears.

In mathematics, rYZ is sometimes used to denote a radial measure in the YZ plane, defined as rYZ = sqrt(Y^2 + Z^2). In cylindrical or polar-like coordinate systems, rYZ can serve as a local radius for a cross-section perpendicular to the X-axis. In simulations and models, rYZ may denote a distance or interaction radius that depends on Y and Z, expressed as r = f(Y,Z).

Beyond formal usage, rYZ has appeared in science fiction and thought experiments as a placeholder name for a device or boundary that links the Y and Z domains, such as a portal, relay, or interface.

Origin and usage notes: The combination of letters Y and Z with r reflects common coordinate notation, making rYZ a convenient, language-agnostic symbol for a radius-like quantity depending on Y and Z.
