Notes to myself.

1. Torsion re: http://en.wikipedia.org/wiki/Torsion_%28differential_geometry%29 re: "It is positive for right-handed spirals and negative for left-handed ones." "spirals" should be "helicies". Wictionary gives spiral as alternate for helix but "not in technical usage". The spiral is a 2D figure and can have no torsion. Check handedness. --SteveZins 02:14, 19 March 2006 (UTC)
