I was reading a book which had some comments on EPR paper (Einstein, Podolsky, Rosen - 1935) like following:
In Newton's physics, when two identical billiard balls hit each other head-on, bouncing off in opposite direction, knowing one ball's position and speed will also indicate other ball's position and speed. However, in quantum physics, when two particles A and B collide, you can either measure A's momentum which let's you infer B' momentum or you can measure A' position instead to infer B's position.
Now, is it possible to measure A's momentum and B' position there by inferring other attributes of each other? I suspect not, but can someone help to explain why not?
Thank you.
