From: Archimedes Plutonium on 20 Jul 2010 12:28 Based on the below post I should number this post as 4.01 so as to squeeze this thread into my book: From: Archimedes Plutonium <plutonium.archime...(a)gmail.com> Newsgroups: sci.math,sci.logic Subject: Wikipedia's flawed IP and here is how it should read #4; 2nd ed; Euclid's Infinitude of Primes Proof Corrected Date: Sat, 22 Aug 2009 23:15:41 -0700 (PDT) --- end quoting old post --- Now then, recently David Tribble posted the below: Archimedes Plutonium wrote: > David R Tribble wrote: (snipped) > > > > W-1 is not necessarily prime. > > Consider 2 x 3 x 5 x 7 - 1 = 209 = 11 x 19. > > Yours is direct. > > Indirect, W-1 and W+1 are always necessary new primes, but do not feel > bad because most > mathematicians never got that correct either. > > That is why Twin Primes was never proved So David still does not understand the Indirect Method and my answer to him should have been more crisp and better explained. I should have gone into more detail. So let me do that here and now. David, in the Indirect we have (1) Definition of prime (2) Suppose 2,3,5,7 are all the primes that exist where 7 is the largest (3) form P-1 and P+1 which are 209 and 211 (4) both are necessarily new primes because 2,3,5,7 are the only existing primes given the hypothetical supposition and by definition of prime 209 and 211 are indeed primes in this space (5) contradiction that 7 is the largest prime (6) primes are infinite So you see David Tribble and Chandler Davis, that no matter what primes you list for the supposition step, the hypothetical supposition step, the definition of prime in conjunction with the fact that a division leaves a remainder will give you twin primes necessarily in this method. If 3 and 5 are the only primes in existence, then the definition of prime and the Indirect Method entails that 14 and 16 are necessarily two new primes in this space. Now I am including Chandler Davis of Mathematical Intelligencer since by email he also is like David Tribble in not understanding how the Indirect method works and delivers Infinitude of Twin Primes proof. Of course, in the Infinitude of Twin Primes, in the Indirect the twin primes are not numbers like 14,16 nor are they numbers like 209 and 211, but in the proof schemata, they are a pair of generalized twin primes as P-1 and P+1. And Twin Primes are infinite because once I do a proof of one pair say P-1 and P+1, I throw that pair into a recursive second proof and yield out Q-1 and Q+1, and the recursion goes on infinitely many times. So what the Chandler Davis's editing of Hardy/Woodgold article in Mathematical Intelligencer without due reference to Archimedes Plutonium's work that preceded Hardy/Woodgold by 2 decades, is the recognition of Chandler Davis that not only did the math community not understand whether Euclid's proof was constructive or contradiction, but they failed more importantly to see that Euclid's Indirect is a proof of the Infinitude of Twin Primes. Chandler, from his email, fails to recognize that P-1 and P+1 are necessarily new primes in that method. And the only reason Twin Primes was never proven before, is because no- one had a valid Indirect Method in their head. And David Tribble seems not to recognize that the Structure the framework of logic of the method yields two new primes, no matter what example he throws up. David seems oblivious to the idea that if 3 and 5 are the only primes to exist, it is the method that forces 14 and 16 in this hypothetical space are also primes. And then, when you do it on "generalized numbers" of P-1 and P+1, that they truly are two new twin primes from any finite supposed list of all primes. Mathematicians are supposed to be more logical than anything else, but when it comes to Euclid IP indirect, they seemed to have melted away in the hot summer sun of pointing to irrelevant examples. And I do not know how old Mr. Chandler Davis in Toronto is, whether he is too old to want to change and learn a correct Indirect Euclid IP or whether Chandler ever penned a Indirect Euclid IP. I do know that David Tribble is not a mathematician and doing this out of sheer curiosity and so if David can understand that P-1 and P+1 are necessarily two new primes in the Indirect, then Chandler Davis, the editor of Mathematical Intelligencer should be able to see that these are two new primes and that they are the key to a Infinitude of Twin Primes proof.

From: spudnik on 20 Jul 2010 14:06 how can your proof be sufficient, if there is not enough of a characterization of primes to exclude 3x5 +- 1, or of 209? (not sumorial.) I mean, it's sort of like the sieve of Eratosthenes, constructed with big holes (2, 3, 5, 7, 209, 211), and you did not construct the first-four primes, only assumed them ... so, how could such proving, prove any thing? anyway, if there is some sort of isomorphism between inductive & deductive proof, if they lead to the same statement, then there is probably a simple way to exchange them -- and I hav read it in *Mathematics Magazine*. --BP's Waxman's cap&trade, on the docket pour lees ducs d'oil -- the next (last?)

As AP cannot reason in the astract, he lets his "computational experience" prevent him from making correct deductions. Perhaps a concrete example more suitaed to AP's limited intellect will help him see the error of his ways. Imagine a hotel which is simply an unending row of rooms with a first room and no last room, each room being capable of accommodating any number of guests. Each guest has a copy of the Rules of the Hotel, which are: 1) The only guests allowed into the hotel are Americans, Germans or Estonians 2) Every room, except the first, contains a unique combination of guest nationalities 3) Every combination of guest nationality is found in one and only one room 4) No two guests in immediately adjacent rooms have the same nationality. By 3) There is one and only one room, call it room W, that contains an American, a German and an Estonian. Relaxing in room W, the German, a logician, begins to wonder who is next door. "Rule 2) tells us that there must be guests on both sides but as there is an American, an Estonian and a German in this room, by rule 4 there must be a guests of some other nationality in the two rooms next to ours. But that contradicts rule 1). The only nationalities allowed in the hotel are Americans, Germans and Estonians". "No", says the Estonian. "We could be on the immediate right of the first room -that's empty. So we must be in the second room along". "But who's in the third room?" asks the Estonian. Archie Poo the American then says "Don't you see if the third room contains neither an American nor a German nor an Estonian, then by rule 2, the guest in the room next door is necessarily Italian. "But what about rule 1" shout the others. "There are no Italians in the hotel". Archie Poo is very, very, very stupid, belives that everything he says must be right and simply repeats ad inf what he has said before. Babbling about twin prime conjectures, the Riemann hypothesis and such like. So who is/are in room w-1 and room w+1 ? Could it be an Aztec or a Roman ? Say each guest is assigned a prime number Americans = 5 Germans = 2 Estonians 7 The AGE group is assigned room No 2x5x7 = 70 Room w-1 has the number 70-1 = 69 = 3x23 Obviously no guest has the number 2 or 23 Only Archie Poo thinks what you have deduced using the "rules of the hotel" can be applied to the naturals

If you are assuming that 3 and 5 are the only primes then the set of primes, PRIMES = {3,5}. Consequently, the set of nonprimes must be NONPRIMES = {1,2,4,6,7,8,......} =N\PRIMES The definition of prime in this case is n is prime if it has precisely two distinct divisors and belongs to PRIMES. 7 is a nonprime. It has precisly two distinct divisors (1,7) but 7 does not belong to PRIMES. AP thinks that there are naturals that can be simultaneously in PRIMES and NONPRIMES. PRIMES = {2,3,5} NONPRIMES = {1,4,6,7,8,9,10, ...} 2x3x5+1 = 31. 31 has two and only two distinct divisors but 31 is not an element of PRIMES. 8 is a nonprime. It has four distinct divisors (1,2,4,8) GCD(3x5,3x5+1) = GCD(15,16) =1 All this means is that neither 3 nor 5 divides 16. Two consecutive naturals do not share any common factors other than 1 This is true as 16 = 1x16, 2x8, 4x4, 2x2x2x2 16 is not prime, neither is it a product of primes. If it were prime, it would be in PRIMES Of course, in the naturals every n>1 has at least one prime divisor, so the set of PRIMES in the naturals cannot be {3,5} or any other finite set of primes.

I should have > gone into more detail. I notice that both JSH and AP are working on the Infinitude of Twin Primes, but via different methods. JSH is looking at congruences mod various primes, while AP is attempting to modify Euclid's proof so that it works for Twin Primes. Meanwhile, the following isn't directly related to Twin Primes, but I post it here anyway. In another thread, I pointed out that today, the 22nd of July, is known as Pi Approximation Day since pi is approximately 22/7. The question asked in another thread was, does AP believe that pi is _approximately_ 22/7, or _exactly_ 22/7? (If the former, then maybe he considers today to be Pi _Exactness_ Day...) |
