A certified reference material is a particular form of measurement standard. Reference materials are particularly important for analytical chemistry and clinical analysis. [2] Since most analytical instrumentation is comparative, it requires a sample of known composition (reference material) for accurate calibration.
In contrast to books that are loaned, a reference book or reference-only book in a library may only be used in the library and may not be borrowed from the library. Many such books are reference works (in the first sense), which are usually used briefly or photocopied from and, therefore, do not need to be borrowed.
A general reference is a citation that supports content, but is not linked to any particular piece of material in the article through an inline citation. General references are usually listed at the end of the article in a References section.
Materials science is a highly active area of research. Together with materials science departments, physics, chemistry, and many engineering departments are involved in materials research. Materials research covers a broad range of topics; the following non-exhaustive list highlights a few important research areas.
A material is a substance or mixture of substances that constitutes an object.Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function.
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
Research libraries can be either reference libraries, which do not lend their holdings, or lending libraries, which do lend all or some of their holdings.Some extremely large or traditional research libraries are entirely reference in this sense, lending none of their material; most academic research libraries, at least in the U.S., now lend books, but not periodicals or other material.
In computer science, references are data types that refer to an object elsewhere in memory and are used to construct a wide variety of data structures, such as linked lists. Generally, a reference is a value that enables a program to directly access the particular data item. Most programming languages support some form of
