Engineering

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".

The Iron Man suit wouldn't exist without Tony Stark's intellect or engineering ability. Tony graduated from MIT at age 15 with a dual degree in physics and engineering, and would later attain three advanced degrees in science and engineering. Inspired by a mentor who taught him to value the principles of science and the world, Tony was able to apply his knowledge to create the pacemaker-like device that saved his life, as well as the scrappy Iron Man suit that gave his life meaning.
