Scientific Fields or Categories of Science Specialties

That vocation in science concerned with meteorology which is concerned with the mean physical state of the atmospher together with its statistical variations in both space and time as reflected in weather behavior over a period of many years.

1. The art and technique of using words effectively to impart information or ideas.
2. The field of study concerned with the transmission of information by various means; such as, with print or broadcasting or any of the various professions involved with the transmission of information; such as, advertising, broadcasting, or journalism.
3. Employment in science and technology by which information is collected from an originating source, transformed into electric currents or fields, transmitted over electrical networks or space to another point, and reconverted into a form suitable for interpretation by human receivers.

Employment in the branch of science that promotes knowledge which is concerned with information processes, the structures and procedures that represent these processes, and their implementation in the various information-processing systems.

The work specialty in the science of those systems in which one or more outputs are forced to change in a desired manner as time progresses.

The profession in the science of producing and maintaining very low temperatures, of the phenomena at those temperatures, and of technical operations performed at very low temperatures.

A line of work in the branch of science that deals with the geometric description of crystals, their internal arrangements, and their properties.

An occupation in the branch of biological science that deals with the structure, behavior, growth, and reproduction of cells and the function and chemistry of cells and cell components.

The vocation in a branch of engineering concerned with the design of a product or facility according to generally accepted uniform standards and procedures; such as, the specification of a linear dimension, or a manufacturing practice; for example, the consistent use of a particular size of screw to fasten covers.

Employment in the science of the interrelationships between organisms and their enviroments.

An occupation in the science of physical phenomena involving electric charges and their effects when at rest and when in motion.

The word "electricity" was first used by the English physician Sir Thomas Browne (1605-1682) in 1646. The word "electrode" was coined by the English physicist and chemist Michael Faraday (1791-1867). The words "electrolysis" and "electrolyte" were introduced by Faraday at the suggestion of the Reverend William Whewell.

The branch of physics dealing with the observations and laws relating electricity to magnetism, and with magnetism produced by an electric current.

A branch of science and technology relating to the conduction of electricity through gases or vacuum or through semiconducting materials; concerned with the design, manunfacture, and application of electron tubes.

Te science b which the properties of matter and the sources of power in nature are made useful to humans in structures, machines, and other manufactured products.

The field of acoustics that deals with the production, detection, and control of sound by electrical devices, including the study, design, and construction of such instruments as microphones, loudspeakers, sound recorders and reproducers, and public address systems.

The processes of biological and organic change in organisms by which descendants develop differently from their ancestors, and a history of the sequences of such changes.
