ENGINEERING

Engineering best described as the discipline and skill to acquire and apply scientific, economic, social and practical knowledge in order to design and build structures, machines, devices, systems etc.
Engineers apply the sciences of physics and mathematics to find suitable solutions to problems or to make improvements to the status quo.

Engineering, much like other science, is a broad discipline that 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 often characterized as having four main branches: Chemical engineering, Civil engineering, Electrical engineering, Mechanical engineering.

Beyond these four, sources vary on other main branches. Historically, naval engineering and mining engineering were major branches. Modern fields sometimes included as major branches include aerospace, petroleum, systems, audio engineering, architectural, biosystems, biomedical,  industrial, materials science and nuclear engineering.
