At least 15 types of engineering fields exist, including aerospace, agricultural, automotive, biomedical, chemical, civil, computer, drafting, electrical, environmental, geological, marine, mechanical, petroleum and software engineering. Engineering applies math and science principles to construct engines, bridges, aircraft, plants, ships, roads and mechanical devices.
Aerospace engineering involves design and construction of airplanes, rockets, missiles, spacecraft, satellites and deep-diving submersibles. An aerospace engineer designs, plans, tests, produces and operates aerospace equipment and machinery. Aerospace engineers work for the U.S. government, commercial airlines, military contractors, robotics companies and other organizations.
Electrical engineering involves the use of electricity and light to create tools and devices that improve the quality of life for humankind. Electrical engineers work in fields such as communication, computers, automotive and power generation. Electrical engineering applies the physics of electrons, voltage and electricity to everyday devices, including household appliances, lighting, computers, factory machines and cellular phones.
Geological engineering revolves around mining, forestry and geography. Geological engineers investigate the construction of roads, mines, quarries, dams, railroads, buildings, pipelines and oil rigs. These engineers survey and study subsurface areas for drinking water resources, oil and gas exploration, mineral resources and earthquake potential. Geological engineers work for oil companies, construction contractors, power companies and highway departments.
