Hi!
I know similar questions is in the archives, but please it is a difficult 
problem to grasp (even a little bit).
My question is: if two particals which are correlated from the start are 
separated, and one variable is measured on one of them, you know the value of 
the variable on the other. Whatīs so strange with this??
The particals were sorrelated from the start - one has spin up and the othe spin 
down. If you measure "spin down" on one, the ohter MUST have "spin up", because 
they have the opposite spin from the beginning. I think Iīve got this experiment 
wrong (i.e. I havenīt understood it - although Iīve tried hard to get an 
answer).
Please explain what the curiosity is in this experiment.
Sincerely Mikael!!
