The exp stuff goes here too as so many sums have e or gamma, the latter less known. But if we shared the free software in the schools more, we could up the literacy about history too. We don't do nearly enough with timelines yet (aka "partially overlapping scenarios" -- to echo one of my math teachers, long time subscribers might know which one).
Evelyn Wood Reading Dynamics was a helpful class I took in the Philippines on the side. We met in a skyscraper in Makati, corporate setting. It wasn't the speed reading that stuck with me so much as the emphasis on doing "a recall" after a reading, with an emphasis on graphs for notes, by which I mean edges connecting nodes. Affirmation of that style of note taking was a boost for me. Hypertext came many years later (this was 1970s).
