Quantum entanglement is the strangest quality of quantum reality. Einstein called it "spooky," because, well, it is. Join Brian to explore the basic ideas visually and then take a look at the essential equations. | World Science Festival

Albert Einstein and his colleagues Podolsky and Rosen proposed a simple way to rid quantum mechanics of its most disturbing feature--called non-locality--in which an action undertaken here can affect the result of a measurement undertaken there, even if here and there are far apart. John Bell came up with a way to test Einstein's vision of reality, ultimately showing that Einstein's vision was wrong. | World Science Festival
