  1. A professor at the University of Central Missouri has discovered the world’s largest Mersenne prime number, shattering the previous record prime number according to officials at mersenne.org. It’s only the 48th Mersenne prime to have ever been discovered......

    I'm sure the 17 milliion-digit is the largest known number. There are probably more for people to waste their time finding.

    It's definitely not the largest known number, if you wanted to find that you could paste an infinite amount of 9s. Although this isn't really useful in any way (as far as I know), it's still pretty cool. I actually wanted to set up a program that found prime numbers using GPUs, but never got around to it.

    Anyone else think that this guy should have gotten a grant of more than $3,000? It seems like a trivial amount for what is obviously a historic moment.

    Money for pointless number-crunching... give me a mil, I will get you one 10-times longer, so you can put it in your pipe and smoke, you, time waster, you...

    I *think* you meant " the 17 million digit is NOT the largest".

    If that's what you meant, constants like Planck time and temperature definitely prove your hypothesis. :)
     
  9. from Ars.
    You're missing something there.

    Omg, I so fail at math.

    it was postulated that the 43rd mersenne prime will unlock the gateway to cybertron.

    I'd rather painfully watch justin bieber concert than read this wiki article:

  11. Finding the biggest prime number would break all current cryptographic systems based on random prime numbers

    Are you sh**tin' me? I am so looking forward to Justin Beiber and Taylor Swift releasing a double CD of nothing but duets.......!!

    That would be unconventional, to say the least! They could trash each other, and their exes while looking longingly into each others eyes. And who better to put on the cover but Kanye West, in a referee's uniform......?

    So, the album could be named "Merced", which sounds fairly close to, "mersenne", while meaning "mercy", in Spanish....:p

    LOL, God I crack myself up....

    EDIT: To add a further touch of whimsy & irony, I'd order it through, "Amazon Prime"..
     
  13. Actually, there are uses for large prime numbers. Cryptography is a big one. Just because you don't personally use it does not mean it is useless.

    Wow. That's a big number. Lol I was just thinking what you would use that big of a number for, and you guys gracefully answered my question. hehe nice.

  17. Prime numbers are useful for encryption (and possibly encoding). The larget the prime the better so I would say this is very important.

    Alas, those of us who don't wark in maths do't have much use for it.

    Only $3,000? I guess there's no profit in playing the numbers. :p
