https://en.wikipedia.org/wiki/Turing_machine : In his 1948 essay, "Intelligent Machinery", Turing wrote that his machine consisted of: *... an unlimited memory capacity obtained in the form of an infinite tape marked out into squares, on each of which a symbol could be printed.* So where is there a Turing machine with an actual infinite tape? What building is it in that I can go see it? @philipthrift. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
