Thank you! I didn't know that the entangled desappears, that's the misunderstanding I was looking for. In this case, how could we know that two particles were entangled. If we measure a property from one, how can we compare with the other? Wouldn't the entanglement disappear prior to the second...
Hi, I've heard about the EPR paradox as follows: Leave two entangled particles A and B carried by scientists A' and B', with a pair of incompatible properties (eg spin up/down and left/right) in possible Green/Yellow and Blue/Red states. If one measures Yellow state (eg, particle B in spin up...
Hi, I was trying to solve the classical two body problem with Lagrangian Principle. I replaced the angular velocity before taking the partial derivatives (which respect to the distance to the virtual particle) and the result was completely different. I would like to ask, therefore, which...
