Indeed. But I think I would like to be oriented better, and not feel completely outside it.

My calculus is strongest; I can deal with that basically. My geometry is so poor that I am surprised I passed my maths A level.

These books excite me because they give back that, er, constructivist thing that has always appealed to me -- Piaget, Papert, Minsky.

I enjoyed your article, thank you for writing it.
