   Preparation of electron spin directions   
   26 Feb 19 19:30:36   
   
   I have just written the following in a draft commentary on (someone   
   else's) Bell model.   
      
   "However, I do not believe that electrons can be aligned exactly in a   
   given direction.  That would require measuring along three base axes   
   simultaneously. That cannot happen as only one measurement axis is   
   permitted at a time.  So preparation of an electron in the direction of   
   vector a is a fuzzy process not an exact one.  Particles can change spin   
   axes on detection to reverse the direction of their spin axes.  That   
   suffices to point them in the general direction of (say) vector a.  That   
   is, clearly pointing more towards say vector a rather than towards   
   vector a*, but not pointing exactly in line with vector a."   
      
   This is broadly-speaking true, isn't it?   
      
   [Moderator's note: Due to possibly garbled characters, the vector names   
   might not be what was intended.  It seems that the point is to   
   distinguish two vectors, above denoted by a and a*. -P.H.]
