The Bactra Review Geometry Civilized
As described in a pair of articles by Paulus Gerdes, author of the infamous
Marx Demystifies Caclulus (Minneapolis: Marxist Educational
Publications, 1985, as vol. 16 in Studies in Marxism). This is
one of the silliest books ever written about any mathematical subject, but the
techniques Gerdes describes in those articles are simple and practical enough
that he's probably not screwed them up.
