The idea is, for example, if you put two electrons in close proximity they can't have the same spin direction. If you then pull them apart without measuring which electron has which spin, you can separate them by any distance. and if you measure the spin on one electron, you know "instantly" the other must have the opposite spin. But you can't change the spin of either electron. -- Thomas Jones-Low Work: xxxxxx@softstart.com Home: xxxxxx@gmail.com
