I agree. But to determine the difference between arithmetical truth and arithmetical falsehood matter that obeys the laws of physics is required. That distinction is important, if Michelangelo had just displayed a huge block of natural marble and said David was inside few would say he was a great artist. >> >> >> You confuse what works from what doesn't; and machines made of nothing >> but pure mathematics *DON'T WORK*. > > > > They don't work in the physical reality, > I know, and I can explain why it doesn't work and you can't. > > > It is up to you to tell us what a physical machine can do that a universal > machine cannot do, > A machine made of matter that obeys the laws of physics can correctly inform John Clark that 2 ^ 57,885,161 − 1 is prime, a machine made of nothing but pure mathematics can not.
