Engineering is the application of mathematics, empirical
evidence and scientific, economic, social, and practical knowledge in order to invent,
design, build, maintain, research, and improve, structures, machines, tools, systems,
components, materials, and processes.
The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.
The term Engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".
Engineering is a broad discipline which is often broken down into several sub-disciplines. These disciplines concern themselves with differing areas of engineering work. Although initially an engineer will usually be trained in a specific discipline, throughout an engineer's career the engineer may become multi-disciplined, having worked in several of the outlined areas. Engineering is often characterized as having four main branches:
Beyond these four, a number of other branches are recognized. Historically, naval engineering and mining engineering were major branches. Modern fields sometimes included as major branches are manufacturing engineering, acoustical engineering, corrosion engineering, instrumentation and control, aerospace, automotive, computer, electronic, petroleum, systems, audio, software, architectural, agricultural, biosystems, biomedical, geological, textile, industrial, materials, and nuclear engineering.

Definition
The creative application of scientific principles to design or develop
structures, machines, apparatus, or manufacturing processes, or works utilizing
them singly or in combination; or to construct or operate the same with full
cognizance of their design; or to forecast their behavior under specific
operating conditions; all as respects an intended function, economics of
operation or safety to life and property.
Sub-Disciplines
Engineering is a broad discipline which is often broken down into several sub-disciplines. These disciplines concern themselves with differing areas of engineering work. Although initially an engineer will usually be trained in a specific discipline, throughout an engineer's career the engineer may become multi-disciplined, having worked in several of the outlined areas. Engineering is often characterized as having four main branches:
- Chemical engineering – The application of
physics, chemistry, biology, and engineering principles in order to carry
out chemical processes on a commercial scale, such as petroleum refining, microfabrication,
fermentation, and biomolecule production.
- Civil engineering – The design and
construction of public and private works, such as infrastructure (airports,
roads, railways, water supply and treatment etc.), bridges, dams, and
buildings.
- Electrical engineering – The design and study
of various electrical and electronic systems, such as electrical circuits,
generators, motors, electromagnetic and/or electromechanical devices, electronic
devices, electronic circuits, optical fibers, optoelectronic devices, computer
systems, telecommunications, instrumentation, controls, and electronics.
- Mechanical engineering – The design of
physical or mechanical systems, such as power and energy systems, aerospace/aircraft
products, weapon systems, transportation products, engines, compressors, powertrains,
kinematic chains, vacuum technology, and vibration isolation equipment.
Beyond these four, a number of other branches are recognized. Historically, naval engineering and mining engineering were major branches. Modern fields sometimes included as major branches are manufacturing engineering, acoustical engineering, corrosion engineering, instrumentation and control, aerospace, automotive, computer, electronic, petroleum, systems, audio, software, architectural, agricultural, biosystems, biomedical, geological, textile, industrial, materials, and nuclear engineering.
