People tend to take things like roads, bridges, tunnels, and mass transit for granted. They expect the garbage to be picked up and the water to flow from their faucets. But in order for all these mundane aspects of life to be serviceable and available to the general public, there must be a dedicated group of people willing and able to work to keep the infrastructure running. This chapter provides a snapshot of some of those jobs.
Simply put, engineers use science and math to develop solutions to technical problems. There are many kinds of engineers, each specializing in a particular aspect of building, planning, or problem solving. Engineers can find careers in government in the fields of aerospace, agriculture, biomedicine, chemistry, civil engineering, electricity, and the environment. They can also help protect public health and safety, design ocean-going vessels, or develop mechanical innovations in engines and turbines.
Aerospace engineers design and test aircraft, spaceships, and missiles and oversee their manufacture. They develop new technologies in structural design, guidance, navigation and control, instrumentation and communication, and production methods. Some also specialize in specific types of aerospace products, including commercial aircraft, military fighter jets, helicopters, spacecraft, and missiles and rockets. As changing times call for new innovations, including the possibility of a need to fight new kinds of wars, these kinds of engineers are likely to be in demand. There always has been,
