What is Engineering: Definition and 996 Discussions

Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. 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. See glossary of engineering.
The term engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".

    Is it possible to make science as marketable as Engineering?

    Hi guys. As you may know there is a big distinction between Science and Engineering. Richard Feynman said that Science doesn't have a target, like Engineering has. Science is about studying the universe, and you can do it by focalizing your attention on the Biology, on the Chemistry, on the...
