If one observer finds the spin, and the spin of the other particle is automatically known, how is the second observer going to know that he should look at the half-wit number two at the correct time? Would they not need to look *simultaneously* at the particle to find out? Which defeats a purpose somewhere, I think. Not only that, but can the spin be controlled? If not, how can you transfer information? Just thought I'd ask. ------ --------- ------------------------------------------ erhoogerbeet@watmath.uucp "`The Guide says there is an art to flying,' ehoogerbeets@wateuler.uucp said Ford,`or at least a knack.
