An introduction to engineering
Engineering is a profession in which knowledge of the mathematical and physical sciences is applied to the efficient use of the materials and forces of nature. An engineer is therefore a person who has received professional training in pure and applied science; however, there are also individuals such as technicians and drafters who apply scientific and engineering skills to technical problems.

Engineering gained serious ground in the 19th century where a large number of engineering specialities were being introduced; the 20th century saw even greater advances. Today, engineering is characterized by the broad application of systems engineering principles.

Engineers in industry work not only with machines but also with the people using them, to determine, for example, how machines can be operated most efficiently and safely by workers. Engineers spend much of their time asking questions. They may talk with production workers, as well as technical or administrative staff. It is not unusual for engineers to be involved in several projects at once.

Licensing and computerization are the most widespread among various recent trends in the engineering profession. Approvals by professionally licensed engineers are required for construction of public and commercial structures, especially installations where public and worker safety is a consideration. In Britain the Royal Academy of Engineering, founded in 1976, is concerned with the relationship of engineering to society.

The following list includes the main engineering specialities: Aerospace engineering; chemical engineering; civil engineering; electrical and electronic engineering; mechanical engineering; military engineering; nuclear engineering; and sanitary engineering.

There are also many other engineering fields, including: acoustic engineering; architectural engineering; automotive engineering; transport engineering, and textile engineering.
