hrmmph! signed, an engineer.
I have known many engineers that operate by saying "I know it is this way. I want it to be this way. And I will keep doing it until it is this way" - ignoring the theoretical underpinnings of the subject.
I even know one who was convicted of fraud against Uncle Sam because of this attitude. He ruined the careers of himself and a number of tother engineers as well. And I don't think it was a coincidence that he was a Creationist.
