## Main Question or Discussion Point

Suppose you have an EPR pair, it's in a state [tex]|\uparrow>|\uparrow> - |\downarrow>|\downarrow>[/tex].

Then you measure one particle in the [tex]\uparrow[/tex] direction, and the other particle's measured in the [tex]\rightarrow[/tex] direction. So the result is something like [tex]L\uparrow, R\rightarrow[/tex] or [tex]L\uparrow, R\leftarrow[/tex] etc.

The pair started out with 0 angular moment. But the "measured" particles don't have a net 0 angular moment. How is this consistent with angular moment. conservation?
