Torque,
A surgeon once said to me that he could teach me to take somebody's kidney stones out in a couple of hours. But it would then take him another 5 years to teach me how to deal with everything else that might go wrong whilst you were doing so.
I think this principle probably applies to Engineering and it's various licenses, or to flying and an ATPL. I certainly find regularly, particularly in tracking down problems, I'm using all sorts of apparently unrelated Engineering theory.
