    I'm aiming straight at the EFF prize of $150,000 for discovering a prime number with at least 100,000,000 decimal digits.

    You can join the effort!

  15. Re:I didn't RTFA by Geoffreyerffoeg · · Score: 4, Informative · on There Are Infinitely Many Prime Twins

    Because as numbers get higher, there are a lot more numbers below that can be factors, and thus the frequency of prime numbers decreases. E.g., between 1-10 we have 5 prime numbers, but between 1000-1030 there are only 4. This amusing animation that generates prime numbers demonstrates that prime numbers are more rare as you approach infinity (i.e., the program's "prime density" drops).

    Thus it would make sense that the probability of having a twin prime would drop. The question is if it drops to zero or not.

    It can be demonstrated that there are infinite primes, though, by saying that if there were a finite set of primes, you can get a new number by multiplying all the known primes and adding one. This number divided by any of the known primes always gives a remainder of one. Thus it has no prime factors, and is prime. We would then tend to believe there are infinite twin primes, but this is not so easily proven.

  19. Detection? How about these.. by Tukai · · Score: 1 · on Robot Mine Smasher

    I sure wouldn't feel safe going to a field after it'd been inspected by a bunch of robots,
    however sophisticated mine detection gadgets they might have.
    Wonder if any common antipersonnel/vehicle mines could survive the hammering this monster can offer?
    RA-140
    theres also one in action:
    Raisu in action
    (ok pics, sorry about the Finnish..)

    The robots might do a good job on really unaccessible terrains but for clearing up bigger areas, these offer more *bang* for a buck I think.
    Cheap, easy to operate and robust.
