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".

    Bold, Monster, Engineering Successes

    For many years, I viewed the Saturn V rocket project as the most bold, most wildly successful engineering project ever completed. Most impressive was the lack of tolerance for failure, lack of opportunity for trial and error, achievement of zero complete failures, and the very short timetable...
