GE CLST 73A Lecture Notes - Lecture 12: Universal Turing Machine, Turing Machine, Adding Machine
Document Summary
If thinking is a mechanical procedure, then it could be carried out by a turing machine. Plasticity of the the brain can be seen as a change in the tape on the turing machine. Turing machine is a first model of a computer. Laptop:universl turing machine ; calculator : normal turing machine. Turing showed that on mechanical procedure ( universal turing machine) that can perform any universal mechanical procedure. Thinking can be applied to any intellectual task, so if it is a mechanical procedure, hen its could be characterized by a universal turing machine. The mind could be a mechanical procedure without being limited on what it can do. Flexibility of utm and the a human mind are different. Utm follows rules where a human mind has more flexibility. Objection rests on a lack of imagination. a computer can decide what to do by running a program that makes a decision.
