Let’s Begin…

When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. But one of his greatest contributions to the field actually came in the form of an odd philosophical footnote in a 1935 paper he co-wrote -- which ended up being wrong. Chad Orzel details Einstein's "EPR" paper and its insights on the strange phenomena of entangled states.

Entangled states produce perfect correlations between measurements on two different objects in two different locations—knowing the outcome of one measurement tells you the result of the other with perfect accuracy. Can you think of a classical example of two measurements whose results are not known in advance but are perfectly correlated?
