Turing's Machine

Wondering whether a machine can think, the English mathematician Alan Turing described the following thought experiment. He imagined a locked room with a computer inside. Questions can be fed into the room, and its hidden inhabitant must reply. If, based on such a dialogue, we cannot determine whether the inhabitant is human or machine, then the machine can think.
