Are Computers Ready to Create Mathematical Proofs?

DoraLives writes "Interesting article in the New York Times regarding the quandary mathematicians are now finding themselves in. In a lovely irony reminiscent of the torture, in days of yore, that students were put through when it came to using, or not using, newfangled calculators in class, the Big Guys are now wrestling with a very similar issue regarding computers: 'Can we trust the darned things?' 'Can we know what we know?' Fascinating stuff."

    > 'Can we know what we know?' Fascinating stuff.

    Reminds me of Rumsfeld... "Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know."

    Mathematics is just Symbol Manipulation. I suspect computers are pretty good at that.

    The obvious solution is to have the computer create a new proof that shows that the algorithm it used to create the original proof is, in fact correct.

    And to prove that the proof of the proof can be trusted, have the computer create a proof of the proof of the proof.

    No matter what the proof, don't we still have to accept blindly on faith that A=A?

    Sure, it seems highly probable but.. I just.. I guess I'm a skeptic. All of logic seems like a joke to me, as long as this one little potentially huge loophole looms in the background...

    Fortunately for you software researchers haven't programmed computers to create their own long sentences with so many prepositions that human readers of the created sentences are unable to remember the subject or figure out which verb, or possibly adjective, the trailing adverb applies to by the time they have read the entire sentence yet!

    "For a famous example, it would provide a great deal of peace of mind if we could prove that P != NP."

    Well, P == NP for N = 1.

    That's the beauty of a counter example.

    What computer?

    A computer whose merest operational parameters I am not worthy to calculate and yet I will design it for you. A computer which can calculate The Question to the Ultimate Answer. A computer of such infinite and subtle complexity that organic life itself will form part of it's operational matrix. And it will be called.. The Earth.
