Metrology is "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology" as defined by the International Bureau of Weights and Measures (BIPM).

The field of metrology is important for establishing a common understanding of units, which is crucial in linking human activities.

Modern metrology has its roots in the French Revolution, with the political motivation to harmonize units all over France, a proposal was made to create a length standard borrowed from a natural source.

This led to the creation of the decimal based metric system in 1795 to establish a set of standards for other types of measurements.

Several other countries adopted the metric system between 1795 and 1875 and to ensure conformity between the countries, the Bureau International des Poids et Mesures (BIPM) was established by the Metre Convention.

This has since evolved into the International System of Units (SI) as a result of a resolution made in the 11th Conference Generale des Poids et Mesures (CGPM) in 1960.

Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.

Optics usually describes the behaviour of visible, ultraviolet, and infrared light.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.

The scope and application of a measurement is dependent on the context and discipline.

In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures.

However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales.

Manufacturing is the value added to production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation.

The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale.

Such finished goods may be sold to other manufacturers for the production of other, more complex products, such as aircraft, household appliances or automobiles, or sold to wholesalers, who in turn sell them to retailers, who then sell them to end users and consumers.

In geometry, a coordinate system is a system which uses one or more numbers, or coordinates, to uniquely determine the position of a point or other geometric element on a manifold such as Euclidean space.

The order of the coordinates is significant, and they are sometimes identified by their position in an ordered tuple and sometimes by a letter, as in "the x-coordinate".

The coordinates are taken to be real numbers in elementary mathematics, but may be complex numbers or elements of a more abstract system such as a commutative ring.

The use of a coordinate system allows problems in geometry to be translated into problems about numbers and vice versa; this is the basis of analytic geometry.
