Aerospace engineers design aircraft for both commercial and military purposes. In addition to airplanes, they also design and manufacture missiles, spacecrafts and other aviation technologies. Often, their job requires creative and innovative thinking. Within aerospace engineering, many specialties exist such as propulsion, control systems and thermodynamics.
Chemical engineers apply principals of chemistry into their jobs of manufacturing daily supplies such as food, beverage, paper, skincare products and energy. They develop, test and produce products and treat the byproducts. They can also work in health care and technology. Graduates of chemical engineering often have a wide array of industries from which to choose.
Civil engineers build roads, highways, buildings, tunnels, sewage and other transportation- and construction-related structures. They engage in all aspects of a construction project including cost estimation, safety review, environmental issues and federal regulations. Civil engineering also splits into sub-disciplines such as structural, construction, transportation, environmental and geotechnical.
Electrical engineers design, develop and test electrical systems. These systems include lighting and wiring in buildings, communication systems, machines, electrical utilities and electrical systems in cars and airplanes.
Mechanical engineers design and produce engines and machines. Many work in the automotive and aerospace industry, but also make other machinery products such as air conditioners, refrigerators, elevators and robots. Mechanical engineering curriculum looks similar to aerospace engineering, except classes have broader subjects.
Mining engineers design mines, shafts and underground tunnels to extract materials from beneath the earth's surface to refine and then use in other products. Some design equipments, some analyze underground materials, and others work on safety and regulation of the mines.
Nuclear engineers use their knowledge about nuclear energy and radiation to construct devices that create nuclear power. Many work for nuclear power plants, and others work for the government or academic institutions. At nuclear power plants, the engineers are responsible for operation and supervision of the facilities, as well as maintaining radiation safety.
