Hi all-
My GA posting (2d revised edition) is now on the web at http://gate.hep.anl.gov/jlu/quatern.pdf.
Changes: Eq. (1) cleaned up, typo in formula for l-squared
corrected, consistent symbol and correct naming of "eccentricity vector".
Thanks to Cosmas Zachos and Bob Sciamanda for comments and Herb
Schulz for improving fonts. I've invited Hestenes to view the posting.
Regards,
Jack

"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.)"
