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!

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, typo? winter<30C summer>30C doesn't seem like much of a swing if winter is 29 and summer is 31.

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

Perhaps colder than -30°C ?

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

And an other sighting:
http://www.nu.nl/news/1747834/87/Gro...t_ontdekt.html (crappy since it does not really mention GIMPS nor the prize of EFF but they refer to ANP as the source so probably other Dutch newspapers might pick this up sometime this week.

Well done!

(...) Gegenproben des weltweiten Primzahlsuch-Projektes «Gimps» (Great Internet Mersenne Prime Search) hätten bestätigt, dass die Zahl der amerikanischen Forscher (2 hoch 43112609)-1 die größere der beiden sei. (...)

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

Too bad this forum won't let me attach the wav file.
