well I hope this clears everything up for you. It leaves me just as confused as ever. But it is a fascinating read...

From the page: But there's another possible interpretation. Perhaps the particle's spin is completely determined -- but depends on something else about the state of the universe. That would be like a player in "Twenty Questions" who has decided his object is a donkey whenever his opponent starts a question with "Is," and that his object a horse otherwise (or using any other arbitrary but consistent rule). For example, if his opponent asked, "Is it something with big ears?" he would say "yes," but if his opponent asked, "Does it have big ears?" he'd say "no." In that case, his answers are predetermined even though he has no single object in mind. Conway and Kochen say that they have now proven that particles' responses can't be pre-determined, even within this possible interpretation. "We can really prove that there's no algorithm, no way that the particle can give an answer that is unique and can be specified ahead of time," Conway says. "I'm still amazed that we can actually manage to prove that."

From the page: "Do subatomic particles have free will?" ... "Kochen and Conway say the best way out of this paradox is to accept that the particle's spin doesn't exist until it's measured." ...

From the page: The finding won't give many physicists a moment's worry, because traditional interpretations of quantum mechanics embrace unpredictability already. The best anyone can hope to do, quantum theory says, is predict the probability that a particle will behave in a certain way.
