Text: "Running backwards the Mermin device: Causality in EPR correlations." At the microlevel, causality has no time arrow (direction in time). This sort of hard paradox requires a paradigm shift in physics. The familiar (although far from clear cut) concepts of reality, locality, and causality, are all more or less challenged by the actual existence of the "paradox" as experimentally demonstrated. American Journal of Physics. 51(6), June 1983. p. 513-516.
