I've got an abstract mind. I'm good with numbers, vectors, curvatures, tensors... you name it. I guess "abstract mind" is one of the signs of NT-ness (wasn't N the abstract side?) Of course, this means I'm above average intelligence... if you test intelligence with math.
Otherwise, I'm just your average girl. That's why I prefer to say I'm "good at math". It's a bit more modest and a lot more true.
I've once taught a class of future electricians. They assumed that, because I could do these impossible things like finding the zeroes of a parabola (which is, in my opinion, EASY), I was all-round "smart" and knew everything. So they started asked questions about electric circuits. Now, I know Ohms' law and a few other very basic things, but how to build a circuit that can make an electric motor turn both directions, including a safety for when a stupid guy switches the forward moving motor into reverse without stopping it??? No idea.
They were baffled. "But you're INTELLIGENT! You can do math! What are you going to do then when there's some problems with the electricity at your house?"
I had the perfect answer: "Call an electrician, of course. Maybe I'll call YOU!" But they still struggled with the concept that they could be smarter than their math teacher... In my opinion, one of the most important tasks of a teacher is making the students feel they can be smart too.
