...just as it's rare to find an English major that's good at math.
Curiously, though, by far the majority of my math professors have impressed me as being exceptionally well-read, erudite and articulate. I can honestly say they were an inspiration to me, to the extent that I sometimes felt that it would have been worthwhile to study math more than as a discipline incidental to my other studies.
However, honesty compelled me to admit that although I can comfortably handle a differential equation, I would never be more than a plodder in the context of post-graduate math, which is where you only begin to scratch the surface of new ground.
