11) Nonlocal correlations between the Canary Islands
This is an excellent blogpost on the blog
BackReaction. It discusses the role of nonlocality in Bell's theorem, in particular the
locality loophole and the
freedom-of-choice loophole.
Prerequisite: Understanding of
Light cones. Here are some
practice questions on light cones.
12) Is the moon there when nobody looks? Reality and the quantum theory
This is a very intuitive article by David Mermin. He introduces machines that have 3 settings and two lamps (red and green) and shows that assigning 3 "real" properties to particles results in a contradiction.
13) Spooky Actions At A Distance?: Oppenheimer Lecture
A lecture by David Mermin on EPR and Bell's theorem. Here, he uses three entangled particles (see
Greenberger–Horne–Zeilinger state) instead of two.
I recommend watching this lecture after you have read
12).
