Finding the biggest prime number ever

This isn't nerdy at all. This is something I would totally use if I were trying to pick up girls at the bar.

San Francisco, CA - infoZine - A worldwide volunteer computing project called the Great Internet Mersenne Prime Search (GIMPS) has discovered a 12-million-digit prime number, netting $100,000 and a Cooperative Computing Award from the Electronic Frontier Foundation (EFF) for discovering a prime number of over 10 million digits.

The GIMPS PrimeNet network made the discovery on a computer at the University of California, Los Angeles (UCLA) Mathematics Department. Computing manager Edson Smith installed and maintained the GIMPS software at UCLA, and thousands of other volunteers also participated in the search process. The discovery was hailed by Time magazine as the 29th top invention of 2008.

That's freakin' huge number by the way. I'm not sure you could count that one on your fingers.

The winning number is the 45th known Mersenne prime, written shorthand as 2 to the power of 43,112,609, minus 1. A Mersenne number is a positive integer that is one less than a power of two. The GIMPS discovery was announced in the Fibonacci Quarterly journal in August of this year; it is the largest prime number ever discovered.

Yeah this isn't something you'd use on the T-80 in high school.
