Please be explicit. AG * *I'm not sure what you mean by that. Place a point at the center of a Stern–Gerlach magnet and place another point randomly at any point on the outside circumference, draw a line between those two points in extended in both directions to infinity, that is one axis, arbitrarily call one direction along that axis "up" and the other direction "down". Now draw another line 90° from the first one, that is your other axis, pick one direction along that axis at random and call it "left", and the other direction "right" * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> I don't follow. Isn't UP / DN along the path taken by the electrons when they exit the apparatus? How is RT / LT defined? AG If UP/DN is along the path taken by the electrons as they exit the apparatus, and RT/LT is oriented 90 deg wrt to that axis, then UP or DN cannot be written as linear sum of RT/LT. It's like claiming the unit vector along the x-axis, can be written as a linear sum of unit vectors along the y-axis in the plane.
