I have seen in this forum number of discussions about problems of spin visualization. I think the problem is that spin usually is visualized as rotating charged billiard ball. But this classical picture requires that this billiard ball after any time interval resembles itself just with different orientation in space. I have taken a bit different approach and I can visualize spin quite fine. That is instead of assuming that this billiard ball resembles itself at any time I assume that it resembles itself only after certain periods of time meaning that it has some phase space where similarities are seen when you compare the same states from phase space. Let me describe this with diagram (elementary 1/2 spin particle - electron): Code (Text): (P->)~( ) after full period (2Pi) ( )~(<-P) after full period (2Pi) (P->)~( ) Now magnetic field of particle comes from periodic displacement of charge between two points in space. Another thing as can be seen from this diagram is that particle has the same orientation in space after two periods. If we take spin 1 particle (photon) instead we have different diagram: Code (Text): (P->)~( ) after full period (2Pi) ( )~(P->)~( ) after full period (2Pi) ( )~(P->)~( ) There we have the same orientation in space after one period. So I thought that maybe someone will find this visualization helpful.
