Hi all-
For a historical review and evaluation, see the recent paper in AJP for
Sept 2002 by Silva and Martens, Vol70, p. 958 ("Polar and axial vectors

"What did Barrow's lectures contain? Bourbaki writes with some
scorn that in his book in a hundred pages of the text there are about 180
drawings. (Concerning Bourbaki's books it can be said that in a thousand
pages there is not one drawing, and it is not at all clear which is
worse.)"
