Because the primes are trivial to identify in T-space, and trivial to identify as being countably infinite.BlackMephhttps://www.blogger.com/profile/02745499320156194052noreply@blogger.comtag:blogger.com,1999:blog-3826164796564330590.post-36537503704742648532008-04-05T11:45:00.000+02:002008-04-05T11:45:00.000+02:00enginerd, Aigner and Ziegler's Proofs from The Boo...enginerd, Aigner and Ziegler's <I>Proofs from The Book</I> gives six, including this one.<BR/><BR/>The others they give are not nearly as elegant, in my opinion. They are: Fermat numbers are all relatively prime, so there are infinitely many primes; any prime factor of 2^p-1 is greater than p; the number of primes below n is greater than log n; Furstenburg's topological proof; and, the sum of 1/p diverges.Quizhttps://www.blogger.com/profile/01935712406320139010noreply@blogger.comtag:blogger.com,1999:blog-3826164796564330590.post-32604513593726137402008-03-23T04:02:00.000+02:002008-03-23T04:02:00.000+02:00Oh, and btw, you're lucky to have a girlfriend who...Oh, and btw, you're lucky to have a girlfriend whose interested in math.

And it wouldn't work if 1 were prime. That's sort of interesting philosophically, I think, if not mathematically.Enginerdhttps://www.blogger.com/profile/17044844593040395935noreply@blogger.comtag:blogger.com,1999:blog-3826164796564330590.post-72604343224211070092008-03-23T04:00:00.000+02:002008-03-23T04:00:00.000+02:00This comment has been removed by the author.Enginerdhttps://www.blogger.com/profile/17044844593040395935noreply@blogger.comtag:blogger.com,1999:blog-3826164796564330590.post-16748190123105175822008-03-04T11:16:00.000+02:002008-03-04T11:16:00.000+02:00Scientists Ask Congress To Fund $50 Billion Scienc...<A HREF="http://www.theonion.com/content/news/scientists_ask_congress_to_fund_50" REL="nofollow"><BR/>Scientists Ask Congress To Fund $50 Billion Science Thing</A><BR/><BR/>"Another diagram presented to lawmakers contained several important squiggly lines, numbers, and letters. Despite not being numbers, the letters were reportedly meant to represent mathematics too. The scientists seemed to believe that correct math was what would help make the science thing go."Graha/V\https://www.blogger.com/profile/16072516650932490004noreply@blogger.com
