Yeah, it's likely it'll take a long time to fix it.

Gerald Tenenbaum [u-nancy.fr] (the guy who pointed out the mistake) is quite well known, so if he feels that this affects the paper badly, it's probably quite true - and it maybe a while before people get around coming up with an alternative.

(I know this because Tenenbaum is known to my advisor, Jean Bellissard [gatech.edu].)

I always have had an obsession with the pattern of prime numbers. Now and then I get motivated and download a current list of those discovered. With that I try to find some magical pattern, in hopes of finding a secret message or formula explaining reality. When that announcement was made in the previous slashdot story, I did find the claim of infinite primes to be troubling. From my own observations, I believe the gaps between primes may fluctuate greatly but the maximum and minimums grow ever higher. To me these gaps look like some sort of waveform. If I had better coding skills in the manipulation of sound, I would write a program to generate a sound wave out of these numbers. Does anyone know if this has been tried and if so, what was discovered?

There are definitely an infinitely large number of primes. Proof: assume a finite number of primes p1,p2,...,pn (counting from smallest to largest). Then p1*p2*...*pn + 1 is divisible by none of these (hence is prime) and is larger than pn. This is a contradiction of the original assumption, which must therefore be wrong. Hence there are an infinite number of primes.

Basicly, if you set it up as a probability statement:

p( prime ) -> 0

p( prime pair ) -> 0

The latter will simply go towards 0 a lot faster than the former. All you would need to prove is that there must be one more pair (which is not trivial) and you're done.

Take the greek proof, where you multiply all known primes and add 1. Imagine if you took say, the 1000 smallest primes. All it proves is that there's a prime q <= p1*p2*....*p999*p1000+1. That product will be much much greater than any one of the primes. All it takes it one in the entire interval, and the total is infinite.

First, I assume you mean twin primes. Proving infinite primes is trivial and from ancient Greece. It is a proved fact that there are arbitrarily large gaps in the prime sequence (i.e. infinitely large gaps). And that primes get rarer and rarer, in the limit, infinitely rare. Neither of those means that the number of primes is finite.They are "rare" in some senses, but not others. There are enough of them, for example, that the infinite sum of their reciprocals diverges.

Minor nitpick: q isn't necessarily prime. The smallest counterexample:

However, it does prove that there are prime numbers larger than the last prime used to construct q, which is sufficient for the purpose of proving there are an infinite number of primes.

less than orequal to p1*...).(Explanation - the number constructed isn't exactly divisible by any of the primes used to construct it, since it is one more than a multiple of all of them, so either it is prime itself, or it has prime factors which are larger than the "largest prime" used to construct it. So there is no "largest prime".)
