Engineering is the discipline and profession that applies scientific theories, mathematical methods, and empirical evidence to design, create, and analyze technological solutions, balancing technical requirements with concerns or constraints on safety, human factors, physical laws, regulations, practicality, and cost. In the contemporary era, engineering is generally considered to consist of the major primary branches of chemical engineering, civil engineering, electrical engineering, materials engineering and mechanical engineering. There are numerous other engineering sub-disciplines and interdisciplinary subjects that may or may not be part of these major engineering branches.

Chemical engineering

Chemical engineering is the application of chemical, physical, and biological sciences to developing technological solutions from raw materials or chemicals.

Civil engineering

Civil engineering comprises the design, construction, and maintenance of the physical and natural built environments.

Electrical engineering

Electrical engineering comprises the study and application of electricity, electronics and electromagnetism.

Material engineering

Material engineering is the application of engineering principles to understand the properties of materials

Mechanical engineering

Mechanical engineering comprises the design and analysis of heat and mechanical power for the operation of machines and mechanical systems.
