82 Engineering Questions and Answers:

1 :: What is engineering?

Engineering is defined in the dictionary as the practical application of science and math - and that definition really does capture what engineering is all about, Bringing science with the help of math to life by creating practical, real-world things. So in a very real sense, engineering is applied science.

2 :: Is engineer would be an applied scientist?

Yes! Someone who takes scientific discoveries and theory out of the laboratory and puts them to work in the real world. In short, engineers turn science into reality. So while traditional scientists produce knowledge, as applied scientists, engineers use that knowledge to produce things - products, structures/buildings, machines, technology, complex systems, etc. Just about anything you can think of that is man-made.

3 :: Suppose if that's not what I thought an engineer was?

Unfortunately, engineers haven't done a good job in getting the word out about what they really do (perhaps because they're too busy doing it!). As a result, a lot of misconceptions exist about what engineering is and what engineers do, with people believing engineers to be anything from locomotive train operators to mechanics/technicians, to construction supervisors, to NASA personnel, to generic computer people. But now you know the truth as applied scientists, engineers turn science into reality.

4 :: How exactly do engineers turn science into reality?

By using their technical knowledge of science and math, along with equal doses of creativity and inventiveness, engineers first design something new or improve the design of something that already exists. They then get involved in manufacturing or building that new or better-designed thing bringing it to life. Finally, if it is a complicated thing (for instance, a power plant), engineers also get involved in operating and maintaining it keeping it alive and running in tip-top shape.

5 :: What specific things do engineers design, help to manufacture, build or help to operate and maintain?

Just look around you for the answers - cars, vans and trucks; roads, bridges and highways; trains, planes and buses; computers, cell phones and MP3 players; refrigerators, air conditioners and heating systems; etc. - the engineer's invisible hand in present in almost everything that you and others use and depend upon each and every day. Plus a multitude of other thing that are not as obvious: medical instruments, fire engines, farming equipment, food processing plants, sports equipment, musical instruments and recording equipment - and the list goes on and on.

6 :: Can engineer really make a valuable contribution to society as an engineer, helping better my community, our nation and the world?

Helping to provide everyday things that we all depend on (such as clean water and electricity) to creating the latest in cutting-edge technology (such as biotechnology and nanotechnology), engineers "make a difference" every day, serving in a very real way as the architects of the modern world in which we live.

7 :: Are all engineers the same?

No. Just like scientists, engineers specialize in a particular field (discipline), based on their academic training. So while the main types of scientists out there are biologists, chemists and physicists, in engineering the main types are civil, computer, electrical and mechanical engineers - about two-thirds of all students studying engineering earn a degree in one of those four disciplines. And again like science, there are many other fields that students can specialize in within engineering, such as aerospace, bio-medical, chemical and industrial/manufacturing, which the next most popular engineering majors out there. So don't worry, there's an engineering major out there waiting for you!
