Engineering

Engineering is the science, art and profession of acquiring and applying technical, scientific and mathematical knowledge to design and implement materials, structures, machines, devices, systems, and processes that safely realize a desired objective or inventions

The concept of engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel. Each of these inventions is consistent with the modern definition of engineering, exploiting basic mechanical principles to develop useful tools and objects
The term engineering itself has a much more recent etymology, deriving from the word engineer, which itself dates back to 1325. The word “engine” itself is of even older origin, ultimately deriving from the Latin ingenium (c. 1250), meaning “innate quality, especially mental power, hence a clever invention”

Engineering, much like science, 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 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. Historically the main Branches of Engineering are categorized as follows
a. Aerospace engineering - The design of aircraft, spacecraft and related topics
b. Chemical engineering - The exploitation of chemical principles in order to carry out large scale chemical processing, as well as designing new speciality materials and fuels
c. Civil engineering - The design and construction of public and private works, such as infrastructure (roads, railways, water supply and treatment etc.), bridges and buildings
d. Electrical engineering - The design of electrical systems, such as transformers, as well as electronic goods
e. Mechanical engineering - The design of physical or mechanical systems, such as engines, powertrains, kinematic chains and vibration isolation equipment
f. Materials engineering - Investigates the relationship between the structure of materials at both the atomic and molecular scales and how this relationship relates to the materials macroscopic properties
With the rapid advancement of Technology many new fields are gaining prominence and new branches are developing such as Computer Engineering, Software Engineering, Nanotechnology, Tribology, Molecular engineering, Mechatronics etc
