* Focus: Why We Can’t Remember the Future

Why can we remember the past but not the future? It might seem like a bizarre question, but it’s not obvious why our psychological “arrow of time” should move in the same direction as that dictated by the second law of thermodynamics, which implies that events unfold in the direction that increases net entropy. A report inPhysical Review E suggests that these two arrows of time are forced to coincide by the constraints on what it actually means to remember something.
