p m said:No, it cannot.
Once again, a feature of a genius (not simply a talented person) is to find solutions that no one could think of, often to a problem most people didn't know existed.
This cannot be achieved just by "hard work" - you may be born with it or not. You may never know if you are born with this capability or not, too.
Formal education is quintessential for a "genius" - otherwise he/she would be "reinventing the wheel" at best.
Edit: I felt like I need to clear one point - I am nowhere close to the "genius" category; however, I had a fortune to work with a few people not too far from it. I was always blown away by their ability to relate things that seemed completely unconnected, and make very important decisions quickly and correctly.
Nevermind... We do disagree. You say one on hand "you and Emerson seem to confuse academic excellence with brilliance in engineering," and then that academic genius is "quintessential for a 'genius'..."
Huh? Formal education only tells you ONLY how to reinvent the wheel - Academics teaches you the "box" and the physical rules we are supposed to follow... by definition, does not give you creativity... natural born creativity is what makes a brilliant engineer because only THAT person, with creativity, is prone to finding new ways to solve old problems.
I can - did - study the academic theories and learn them well... but they do NOT tell me how to be creative, nor do they impart brilliance or genius.
So what kind of engineer are you?
