There is no evidence a Turing machine, or any abstract entity for that matter, has a memory at all; its memory is not infinite and it's not unlimited either but is in fact very limited indeed, limited by zero . A Turing machine has ZERO memory. > > > No physical computer built to date has unlimited memory, > But plenty of physical computers have enough memory to get the job done and all physical computers have nonzero memories. > > > so our approximations of ideal mathematical objects known as Turing > machines, will remain approximations. > But no Turing machine has enough memory to get the job done. No Turing machine has enough memory to get ANY job done. No Turing machine has any memory at all. No Turing machine can do anything whatsoever except to simplify things so we can understand how real computers work. > > > There will be things Turing machines can compute, but our physical > approximations cannot compute > There is no evidence for and no reason to think that a Turing machine can compute anything a physical computer can, or anything a physical computer can't, or that a Turing machine can compute ANYTHING. And that's a shame really because Turing machines would be one hell of a lot easier to make than silicon microchips John K Clark > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
