A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. [ 1 ] These measuring tools are used in metalworking or metrology to either set or measure vertical distances; [ citation needed ] the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.
For example: Ψ = Psychology Ψist = Psychologist. Ψ, in biological terms, is a symbol used to represent water potential. Ψ, in astrology, is the symbol that represents Neptune.
The physical symbol system hypothesis claims that both of the following are also examples of physical symbol systems: Intelligent human thought: the symbols are encoded in our brains. The expressions are thoughts. The processes are the mental operations of thinking. English language: the symbols are words. The expressions are sentences.
Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.
Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on. The former type of height gauge is often used in doctor's surgeries to find the height of people. Wire gauge: measuring tool determines the thickness of a wire.
A gauge theory is a type of theory in physics.The word gauge means a measurement, a thickness, an in-between distance (as in railroad tracks), or a resulting number of units per certain parameter (a number of loops in an inch of fabric or a number of lead balls in a pound of ammunition). [1]

In physics, a gauge principle specifies a procedure for obtaining an interaction term from a free Lagrangian which is symmetric with respect to a continuous symmetry—the results of localizing (or gauging) the global symmetry group must be accompanied by the inclusion of additional fields (such as the electromagnetic field), with appropriate kinetic and interaction terms in the action, in ...
