From: |-|ercules on 12 Jun 2010 06:29 Every possible digit sequence is computable to ALL (an INFINITE AMOUNT of) finite initial substrings. ___________________________________________________________________________________________________ 2 or 3 posters on sci.math have agreed with that statement. BTW: ALL (an INFINITE AMOUNT of) natural numbers are in "all natural numbers" incase any of you want to feign comprehension disability. Is it too much for you to fathom that I disagree whether no box containing the box numbers that don't contain their own box numbers is self referential on some level? MAYBE, just MAYBE there is another explanation than sets larger than infinity? Do you believe there are numerous different digits (at finite positions) all along the expansion of some reals that are not on the computable reals list? What does that mean? The only interpretation is "There is a finite substring between 2 digits (inclusive) that is not computable" which is a clear contradiction. Herc -- the nonexistence of a box that contains the numbers of all the boxes that don't contain their own box number implies higher infinities. - Cantor's Proof (the holy grail of paradise in mathematics)

The set of all sets not containing themselves would be a self- referential (aka. impredicative) definition and hence leads to a contradiction (i.e. there cannot be an object satisfying the definition). OTOH, given a collection F of boxes, where each box has a number and contains some numbers, whether or not one of these boxes contains its own number is a precisely defined predicate. For a single box this can be checked because the number n of the box can be determined by assumption and for each number, including that n, it can be determined by assumption, wehteer or not n is in the box. Finally, it is by means of quantification also possible to talk about whether or not the collection of F has the property that any or none of its boxes contains its own number.

What's wrong is the wacky conclusions mathematicians get every time they self reference a collectic set and negate itself. You only make a point with Russell's set by putting it in perspective. i.e. does it mean that there is no set of all sets? Why accept such a naively defined set at all? The smarter definition would be "the set of all sets, that don't contain themselves, barring the set of all sets that don't contain themselves". Obviously it can't contain itself and be viable, so DECLARE THAT FACT. Collective sets come with an E&OE! Herc

Even wikipedia writes "Although the set of real numbers is uncountable, the set of computable numbers is countable and thus almost all real numbers are not computable. The computable numbers can be counted by assigning a Gödel number to each Turing machine definition. This gives a function from the naturals to the computable reals. Although the computable numbers are an ordered field, the set of Gödel numbers corresponding to computable numbers is not itself computably enumerable, because it is not possible to effectively determine which Gödel numbers correspond to Turing machines that produce computable reals. In order to produce a computable real, a Turing machine must compute a total function, but the corresponding decision problem is in Turing degree 0â² â². Thus Cantor's diagonal argument cannot be used to produce uncountably many computable reals; at best, the reals formed from this method will be uncomputable." So, the computable reals are countable, and Cantor's diagonal argument won't show they're uncountable. No one disputes this. Why do you keep insisting that there are people who do dispute it and keep trying to argue with them? You're arguing with people that don't exist.

All YOU have to do is COMPREHEND THAT statement, and you will be IN TOTAL AGREEMENT WITH us. There are infinitely many FINITE digit-strings. You CAN LIST all of them. This is an infinite list OF FINITE strings. It approximates EVERY real (computable or otherwise) to ANY AND EVERY FINITE length, EXACTLY. But what good does it do any "approximation" to get the first finite X digits right, WHEN IT GETS INFINITELY MANY WRONG AFTER that?? > BTW: ALL (an INFINITE AMOUNT of) natural numbers are in "all natural numbers" > incase any of you want to feign comprehension disability. Nobody is feigning anything. You are just speaking ungrammatically. It's not that we don't understand; it's that you can't speak English. Yes, "all natural numbers" does "contain" every natural number, and yes, that is an infinite amount of natural numbers. But that does NOT MEAN that the infinite list of all these FINITE strings CONTAINS even ONE *infinite* string, let alone all of them! > Is it too much for you to fathom that I disagree whether Just stop RIGHT THERE. THIS SENTENE *IS ALREADY UNGRAMMATICAL*. The word that has to follow "disagree" is WITH, NOT "whether"!! > no box containing the box numbers > that don't contain their own box numbers is self referential So do you DISagree with the claim that it is self-referential, or do you ASSERT that it is self-referential? For any function whose domain and range overlap, the question x=f(x) is legitimate and is NOT "self-referential" in any important way. > on some level? It DOES NOT MATTER whether this is or isn't "self-referential"!! It is NOT directly self referential like "this sentence is false", and it is NOT A PARADOX like "this sentence is false". That sentence STOPS being paradoxical if you translate it into the TM world, in any case! The TM that is trying to evaluate it simply fails to halt! > MAYBE, just MAYBE there is another explanation than sets larger than infinity? No, there isn't. EVERY set IS SMALLER THAN its powerset. That is what we proved. We proved it WITHOUT the axiom of infinity -- IT DOESN'T MATTER whether the set is infinite or not. YOU are the one who thinks the infinite case must be somehow different, so the burden of proof is on YOU: HOW is it different?? The availability of all these finite approximations IS IRRELEVANT: THEY ARE *ALL* FINITE, DUMBASS! That means they are right for the first n positions AND WRONG FOR THE INFINITELY MANY AFTER THAT! EVERY element on your countable list IS WRONG INFINITELY OFTEN for MOST reals! More to the point, this "list of all computable reals" you keep talking about is ITSELF the paradoxical (or nearly paradoxical) entity here, since IT is NOT computable! > > Do you believe there are numerous different digits (at finite positions) all along the expansion > of some reals that are not on the computable reals list? > > What does that mean? > > The only interpretation is "There is a finite substring between 2 digits (inclusive) that is not computable" > which is a clear contradiction. > > Herc > -- > the nonexistence of a box that contains the numbers of all the boxes > that don't contain their own box number implies higher infinities. > - Cantor's Proof (the holy grail of paradise in mathematics) |
