Definitions - Fields of Science and Engineering
Fields of science and engineering in this survey consist of eight broad
field categories, each consisting of a number of detailed fields. The broad
fields are life sciences; psychology; physical sciences; environmental sciences;
mathematics and computer sciences; engineering; social sciences; and other sciences,
not elsewhere classified. The term "not elsewhere classified" (n.e.c.) is used for
multidisciplinary projects within a broad field and for single-discipline projects for
which a separate field has not been assigned. The following list presents the detailed
fields grouped under each of the broad fields, together with illustrative disciplines
of detailed fields.
The illustrative disciplines are intended to be guidelines, not sharp definitions;
they represent examples of disciplines generally classified under each detailed
field. A discipline under one detailed field may be classified under another
detailed field when the major emphasis is elsewhere. Research in biochemistry,
for example, might be reported as biological, agricultural, or medical, depending
on the orientation of the project. Human biochemistry would be classified under
biological, but animal biochemistry or plant biochemistry would fall under
agricultural. In no case is the research reported under more than one field. No
double-counting is intended or allowed.
- Life sciences consist of five detailed fields: biological
(excluding environmental); environmental biology; agricultural; medical; and life
sciences, n.e.c. Examples of the disciplines under each of these fields are as
follows:
- Biological (excluding environmental): anatomy; biochemistry;
biology; biometry and biostatistics; biophysics; botany; cell biology; entomology
and parasitology; genetics; microbiology; neuroscience (biological); nutrition;
physiology; zoology; other biological, n.e.c.
- Environmental biology: ecosystem sciences; evolutionary
biology; limnology; physiological ecology; population and biotic community ecology;
population biology; systematics; other environmental biology, n.e.c.
- Agricultural: agronomy; animal sciences; food science and
technology; fish and wildlife; forestry; horticulture; phytopathology; phytoproduction;
plant sciences; soils and soil science; general agriculture; other agriculture, n.e.c.
- Medical: dentistry; internal medicine; neurology; obstetrics and
gynecology; ophthalmology; otolaryngology; pathology; pediatrics; pharmacology;
pharmacy; preventive medicine; psychiatry; radiology; surgery; veterinary medicine;
other medical, n.e.c.
- Life sciences, n.e.c.
- Psychology deals with behavior, mental processes, and individual
and group characteristics and abilities. Psychology in this survey is divided
into three categories: biological aspects; social aspects; and psychological
sciences, n.e.c. Examples of the disciplines under each of these fields are as
follows:
- Biological aspects: animal behavior; clinical psychology;
comparative psychology; ethology; experimental psychology
- Social aspects: development and personality; educational, personnel,
and vocational psychology and testing; industrial and engineering psychology;
social psychology
- Psychological sciences, n.e.c.
- Physical sciences are concerned with understanding of the material
universe and its phenomena. They comprise the fields of astronomy; chemistry;
physics; and physical sciences, n.e.c. Examples of disciplines under each of
these fields are as follows:
- Astronomy: laboratory astrophysics; optical astronomy; radio
astronomy; theoretical astrophysics; X-ray, gamma-ray, and neutrino astronomy
- Chemistry: inorganic; organic; organometallic; physical
- Physics: acoustics; atomic and molecular; condensed matter;
elementary particle; nuclear structure; optics; plasma
- Physical sciences, n.e.c.
- Environmental sciences (terrestrial and extraterrestrial) are, with
one exception, concerned with the gross nonbiological properties of the areas of
the solar system that directly or indirectly affect human survival and welfare.
The one exception is that obligations for studies pertaining to life in the sea or
other bodies of water are reported as support of oceanography and not biology.
Environmental sciences comprise the fields of atmospheric sciences; geological
sciences; oceanography; and environmental sciences, n.e.c. Examples of
disciplines under each of these fields are as follows:
- Atmospheric sciences: aeronomy; extraterrestrial atmospheres;
meteorology; solar; weather modification
- Geological sciences: engineering geophysics; general geology;
geodesy and gravity; geomagnetism; hydrology; inorganic geochemistry; isotopic
geochemistry; laboratory geophysics; organic geochemistry; paleomagnetism;
paleontology; physical geography and cartography; seismology; soil sciences
- Oceanography: biological oceanography; chemical oceanography;
marine geophysics; physical oceanography
- Environmental sciences, n.e.c.
- Mathematics and computer sciences employ logical reasoning with the
aid of symbols and are concerned with the development of methods of operation
employing such symbols and, in the case of computer sciences, with the application
of such methods to automated information systems. Examples of disciplines under
these fields are as follows:
- Mathematics: algebra; analysis; applied mathematics;
foundations and logic; geometry; numerical analysis; statistics; topology
- Computer sciences: computer and information sciences (general);
design, development, and application of computer capabilities to data storage and
manipulation; information sciences and systems; programming languages; systems analysis
- Mathematics and computer sciences, n.e.c.
- Engineering is concerned with studies directed toward developing
engineering principles or toward making specific principles usable in engineering
practice. Engineering in this survey is divided into eight fields: aeronautical;
astronautical; chemical; civil; electrical; mechanical; metallurgy and materials;
and engineering, n.e.c. Examples of disciplines under each of these fields are as
follows:
- Aeronautical: aerodynamics
- Astronautical: aerospace; space technology
- Chemical: petroleum; petroleum refining; process
- Civil: architectural; hydraulic; hydrologic; marine; sanitary
and environmental; structural; transportation
- Electrical: communication; electronic; power
- Mechanical: engineering mechanics
- Metallurgy and materials: ceramic; mining; textile; welding
- Engineering, n.e.c.: agricultural; bioengineering; biomedical;
industrial and management; nuclear; ocean; systems
- Social sciences are directed toward an understanding of the
behavior of social institutions and groups and of individuals as members of a
group. Social sciences include anthropology; economics; political science;
sociology; and social sciences, n.e.c. Examples of disciplines under the fields
of social science are as follows:
- Anthropology: applied anthropology; archaeology; cultural and
personality; social and ethnology
- Economics: economic systems
and development; econometrics and economic statistics; history of economic thought; industrial, labor, and agricultural
economics; international economics; macroeconomics; microeconomics; public finance and
fiscal policy; theory
- Political science: area or regional studies; comparative
government; history of political ideas; international relations and law; national
political and legal systems; political theory; public administration
- Sociology: comparative and historical; complex organizations;
culture and social structure; demography; group interactions; social problems and
social welfare; sociological theory
- Social sciences, n.e.c.: linguistics; research in education;
research in history; research in law (e.g., attempts to assess impact on society of
legal systems and practices); socioeconomic geography
- Other sciences, n.e.c.: This category is used for multidisciplinary
or inter-disciplinary projects that cannot be classified within one of the broad
fields of science already listed.
