The fact that this subject has gotten so much attention proves that engineers and "engineers", ("engineers" - those who think they are but some would challenge) have really big egos, and need to have their titles to feel important.
Anyone can be an engineer in my estimation if they fit the criterial. Orville and Wilber Wright, the 1st and arguable the best aeronautical engineers ever, had no formal engineering training. In fact, Orville didn't even graduate from high school, let alone ABET.
Thomas Alvia Edison. The father of the electrical age, the greatest inventer ever, no formalized engineering training, in fact his mother home schooled him. He never set foot on a college campus.
I could go on forever.
With the great achivements of these men (women) and men (women) like them, only a fool would dare challenge their credentials. These were some of the best engineers the world has yet seen.
Guiness recognizes guiness. Don't look at the title, certificates, or no. of degrees, respect the skills. Real engineers want to be engineers because they love the field. They do things that people say can't be done, or don't want to do. They are a special breed. Real engineers want to feel like engineers. If someone needs to design rockets thats fine. If someone needs to feel like he can solve a differential equation, good enough. If someone needs to know all the asoteric clause of the National Electrical code, good too. If someone needs to come up with a patentable idea, well enough. Regardless, we always recognize our own, the advertisement of a degree makes it obvious, but its not required.
Just so no one says, "he's saying that because he's not an engineer", I have a Bachelors and Masters Degree from an ABET accredited school, I've been practicing for 6 years, and I'm sitting for my PE in April. Yet I still aspire to feel like an engineer.
