Because a wheel is a circle or, rather, possesses circular properties. Now, when one says "a square can't replace a wheel" one could mean "an abstract geometrical shape can't replace an actual physical object", which would be trite and pointless. What one would be assumed to mean would be "a square profile solid object could not be used as a wheel, which requires and object with a circular profile.
Exactly. Thats why I call you out as displaying dishonest tactics. Everyone here knows that for the last 3 years you have been harping on about ideal turing machines vs. actual physical objects.
Everyone has thought your arguments were trite and pointless -- everyone knows an abstract thing can't replace a physical one.
Furthermore, since all computers are turing machines, and all computers are perfectly capable of operating in the time domain, your latter statement above is inapplicable as well.
Similarly, when I say "a Turing machine can't be used for monitoring and control" I don't mean "a Turing machine is an abstract concept which can't do things in real life", I mean "a Turing machine as implemented according to its specification cannot perform monitoring and control, though it can perform computations."
Why can a turing machine, implemented according to its specification, not perform monitoring and control? Because the specification doesn't include the required time domain parameters? Nonsense. I can claim the same of any of your control mechanisms -- if I try to hook them up to something too fast or too slow for their specifications, they won't work.
If it is a real machine, what is the reason? Because it doesn't account for time? Nonsense, if it is a real machine of course it accounts for time. Because it is too slow? Well, it can monitor and control slow stuff, no? Because it is too fast? Well it can monitor and control fast stuff, no?
If you don't mean an abstract turing machine, then the time problem no longer exists -- all machines in reality deal with the time domain.
What is the difference between a real turing machine and any of your control mechanisms that you yourself have worked with?
The constant stream of snide unpleasantness doesn't characterise someone in any way sure of his arguments. IWasp seems able to debate like a decent adult human being, so I don't accept that it's necessary to constantly act like a bad-tempered petulant child.
Sorry, I don't let people get away with dishonest tactics. I know a thing or two about human nature and politics.
