I have several machines that are dropping off the Primenet4 server in favor of the v5 server.

Maybe it's better to track the number of accounts? There are 42574 at the moment.

Have to go to class now...

Yay, the US press has finally woken up! Good to see the story spreading well now. A friend of mine tipped me off that it showed up on the News channel on his Nintendo Wii.

I just heard Edson Smith interviewed on the radio (ABC 702 here in Sydney) as I was waking. Good interview, he explained the distributed computing aspect well and promoted GIMPS. The host Adam Spencer also gave GIMPS a follow-up plug a few minutes later.

It was far better than most of the press articles, which make it sound like you need a large network to be involved, and which frequently don't mention GIMPS.

http://blogs.abc.net.au/nsw/702_breakfast/ is Adam Spencer's page on that website. I don't see any mention of Edson Smith. How can we listen to a record of the interview?

I don't see a way on their website. I've sent a message to them asking if it is possible, but I suspect the answer will be no or $. Btw, don't trust everything on Adam's bio page. I think they're shielding his gentle listeners from his maths degree & time as announcer on a rock station.

I seem to remember a post earlier in this thread claiming that one news source claimed that the announcement of the primes was delayed so as to determine which prime was larger. Does anyone have a link? I think it would be even funnier than any comment Letterman could make on it (speaking of whom, do you have a link for his monologue?)

Either the standard conjectures are wrong, or GIMPS has been very, very, very, very lucky.

Poisson distribution with mean 2 and standard deviation SQR(2).


If you calculate the probability that the number of primes is >6
you will find it is considerably greater than that suggested by
the fact that we are 3 standard deviations from the mean.

You are inviting an unwarranted approximation to a normal
(Gaussian) distribution.

As I said before, your judicious choice of 20M-45M also
skews calculations.

Thank you Techworld.... http://www.techworld.com.au/article/...t_prime_number

That paragraph corrects two errors that most media articles have made. Sadly, the article goes on to make a new error.

I'll have to bring that up with Edson Smith next time I see him; at a rate of 2 digits per second, it would take about 2 and a half months.

Here's a link to the 29 September show - the gag line was

"A group of mathematicians have discovered the largest prime number, which has 13 million digits. Coincidentally, that is the price tag on the Federal bailout."
