Engineering

Engineering is the  branch of science and technology concerned with the  application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of efficient and economical structures, machines, processes, and systems.The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application.

Formal 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 and safety to life and property.

Main Branches of Engineering

Historically the main Branches of Engineering are categorized as follows:

• Aerospace Engineering - The design of aircraft, spacecraft and related topics.
• Chemical Engineering - The conversion of raw materials into usable commodities and the optimization of flow systems especially separations.
• Civil Engineering - The design and construction of public and private works, such as infrastructure, bridges and buildings.
• Computer Engineering - The design of Softwares and Hardware-software integration.
• Electrical Engineering - The design of electrical systems, such as transformers, as well as electronic goods.
• Environmental Engineering - The application of science and engineering principles to improve the environment (air, water, and/or land resources), to provide healthy water, air, and land for human habitation and for other organisms, and to remediate polluted sites.
• Mechanical Engineering - The design of physical or mechanical systems, such as engines, powertrains, kinematic chains and vibration isolation equipment.
