text: is there such a thing as a stupid or dumb genious???   genius only refers to a person's iq rating, which can be just about anywhere on the charts for anyone you meet.  some people have no idea how to start a car, but they could quote to you how to solve algorithims in advanced physics by using pencil shavings.  other people have a very strong practical knowledge (look at a leaky pipe and tell you how to better install plumbing through your house), but have trouble with non-practical knowledge (see the reference to physics above).  everyone is stupid and smart in their own respective ways....that is what makes people so interesting.
