[math-fun] Article in "Science" re learning math via concrete examples vs. via abstractions

Did anyone else see this article: < http://www.nytimes.com/2008/04/25/science/25math.html > ? I'm curious what people's reaction to it was. The original article is not hard to find by googling, though in the interest of probity I shan't post a link. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
