Engineering is the application of math, science, and other practical knowledge in order to invent, design, and build. It is also the “E” in STEM (science, technology, engineering, and math) that has become a hot educational focus in the last few years. There are more than two million engineers in the U.S., and demand is growing. What do engineers do? Is it any fun? How hard is engineering school? I found answers to all these questions and more.
