Your book suggestion does sound interesting, Inky.

I�ll admit to being a weak math student (thought to be underachieving due to high math reasoning scores in K-12. In college, my psychology professor guessed I must be math LD after some IQ testing). In any case, the only time I understood math well was on the few occasions, usually the night before a test, when my parents asked the engineer neighbor to work with me for an hour or so.

I wish every school could waive the certification requirement to allow at least one retired engineer on staff for the math dept.
