[QUOTE=jinydu;142736]I graduated this June. But I know Edson Smith; he is in charge of the computing lab that I used regularly from my first quarter at UCLA to my last.[/QUOTE]

Congratulations, jinydu! It is nice to know that one of our regulars on this forum has a connection to the discovery. Who knows, perhaps one of the computers that you used may have been the one that made the discovery!

[QUOTE=T.Rex;142589]Hey !! Last time I was in Ottawa, it was VERY hot and sunny. I saw some old French houses, but no igloos !

Yes, we have quite the temperature swing here. It can get hotter than 30C in the summer and colder than 30C in the winter. That doesn't take into account the humidex or the wind chill either.

Hmm, I wonder if Cochet knows what the 47th Mersenne prime is.

Look up the region and the correction will be obvious...

And an other sighting:
[url]http://www.nu.nl/news/1747834/87/Grootste_priemgetal_ooit_ontdekt.html[/url] (crappy since it does not really mention GIMPS nor the prize of EFF but they refer to [url=http://en.wikipedia.org/wiki/Algemeen_Nederlands_Persbureau]ANP[/url] as the source so probably other Dutch newspapers might pick this up sometime this week.

Well done! :lol:

Sorry, yes -30C, I have been dealing with 12.9 million digit numbers lately so I forgot to add the negative. :tu:

[QUOTE=petrw1;142715]CONGRATULATIONS to everyone and I'm proud to be part of it all.

In the immortal words of Steven McCrosky (Lloyd Bridges) in Airplane (1980): "Looks like I picked the wrong week to quit drinking."

Too bad this forum won't let me attach the wav file.[/QUOTE]
