# Logic loving people: Check out this great description of an OR gate: ” consider an OR gate. A physical system is an OR gate so long as it sat- isfies the following conditions: (1) it takes two inputs during appropriate finite time intervals, (2) it yields an output during the same time intervals, (3) the inputs and outputs are physical variables that stabilize around two different macrostates—usually called 0 and 1—during the relevant time intervals, (4) the mechanism distinguishes between the two macrostates—0 and 1—reliably, and (5) the output is equal to 1 if and only if at least one of the inputs is equal to 1. Condition (5) states the rule followed by the device.”
