  1. Re:twin primes. on Twin Prime Proof Proffered · · Score: 1

    "All it proves is that there's a prime q <= p1*p2*....*p999*p1000+1"

    Minor nitpick: q isn't necessarily prime. The smallest counterexample:

    2 * 3 * 5 * 7 * 11 * 13 + 1 = 30031 = 59 * 509.

    However, it does prove that there are prime numbers larger than the last prime used to construct q, which is sufficient for the purpose of proving there are an infinite number of primes.

    However, a California voter is MUCH more likely to swing a presidential election that a Montana voter, simply because they can directly affect 54 electoral votes instead of Montana's 3.

    "This statement cannot be proved."

    Of course, Gödel had a lot of i-dotting and t-crossing (heck, even o-dotting!) to do to turn that into the Incompleteness Theorem, but that's what it boils down to. Another good lay-person explanation (along with about 200 logic puzzles to boot) is in Raymond Smullyan's What is the Name of This Book?, ISBN 0139550623.

  7. Re:Damnit it doesn't matter on Slashback: Squashing, N'Synch, Yopy · · Score: 1

    In Mac OS X (10.1.2, anyway), though, typing "America" works (although "amerika" is the common transliteration). It doesn't care about capitalization, and it makes some reasonable guesses for the c_ combos:

    ca ->
    ci ->
    cu ->
    ce ->
    co ->
    cya -> (and so on with the cy_ combos)

    What does capitalization do on other editors? The first thing that I can think of is creating the small characters -- OS X uses a leading "x" for that, so can also be typed as "chixya" (or "tixya").

    Another weird thing: ESPN.com had a feature in their baseball section about the National League pennant race of 1951. They included excerpts of Don DeLillo's novella "Pafko at the Wall," which was the framework for his novel Underworld. ESPN had a link to Amazon.com selling "Pafko at the Wall," which I clicked because I didn't know it was available separately. It didn't have any reviews, so I looked to see what the readers had to say about Underworld.

    Since I've read that book, I probably should've remembered its cover. But, I didn't. Here it is. Compare to this, which got a 2-page spread in Time's special 9-11 issue.

    Actually, all bets (with one exception: a two-line-bet on 0-1-2-3 is really bad) at single-zero roulette in the long run return 97.3% (36/37) of your money. Your system does the same.

    Over 37 spins, you'll spend (say) ¥370. Since each number has a 1/37 probability of being hit, each number can be expected to be hit once in that span. Your expected earnings:

    12 wins on your 1-12 bet (¥5 at 2:1 odds) = 12*¥15 = ¥180
    12 wins on your 13-24 bet (¥4 at 2:1 odds) = 12*¥12 = ¥144
    3 wins on your row bet (¥1 at 11:1 odds) = 3*¥12 = ¥36
    Total gross in 37 spins: ¥180 + ¥144 + ¥36 = ¥360

    I don't think the casinos would have any problem with that.

    If you put all your ¥10 per spin on 2 for 37 spins, you can expect 1 win. At 35:1 odds, you'll win ¥360. (By this, I mean that you can expect in the long run to make back ¥360 of your ¥370. You could very easily double your money at some point -- there's a ~40% chance of hitting 2 in 18 spins.)

    If you put ¥3 on the 17-18-20-21 intersection, ¥2 on red, ¥2 on the first column, and ¥1 each on the digits in your grandfather's birthdate (12, 15, and 19, in my case) for 37 spins, you'll still win ¥360. The actual math (or, as you might say, "maths") is/are left as an exercise for the reader. (It helps if your grandfather was born between 1900 and 1936.)

    As far as maximizing possible earnings, see Duff's comment above. Lots of low-odds bets won't get you far above break-even, and you'll go broke. However, IIRC, single-zero roulette has the best payout of all games against the house unless you're counting cards.

    I truly don't know enough about photography to know if this would even be remotely useful for you, but my Sony DSC-S30 (retail value ~$380) has a 37mm threaded lens mount. It doesn't have a removable lens, though, which I'm guessing is what you'd want.

    A 37mm to T-ring adapter works for astrophotographical purposes, but I don't know (actually, I doubt) if you could do anything constructive with your nice lens on top of the standard lens (f=6.1-18.3mm).

    I'm not really sure how hard it is to go from a picture to a fractal, but it's doable. When you do that, you get a good level of compression. Also, once the picture is encoded as a fractal, you can create much better enlargements than possible with just bicubic interpolation.

    Altamira has a Photoshop plugin, Genuine Fractals, that does this. I haven't tested it out yet, but I remember favorable reviews for it. It only requires a "G1" Mac with 32 megs, so the process of generating the fractals can't be too hard (of course, Photoshop users are accustomed to waiting for ages for something to happen).

    For a (seemingly exhaustive) survey of the state-of-the-art (as of 1999) in fractal image encoding, check out this page, which Google seems to like a lot.

    Actually, from a purely mathematical standpoint, the probability of failure is much greater than that. (Not a statistician per se, but I could've had a BS/Math if I'd filled out the paperwork.)

    There are 6056 out of 6056 safe choices for the 1st wire to fail.

    There are 6052 out of 6054 safe choices for the 3rd wire to fail.
    There are 6050 out of 6053 safe choices for the 4th wire to fail.

    Multiply them up, and that's your probability of a safe launch (it was a launch, wasn't it? I read the article yesterday, and haven't reread it). Subtract that from 1, and you get the probability of a failure.

    Doing the arithmetic, the probability of failure is 1 in 1,009.25. Almost exactly the same as winning a Pick-3 lotto game, of course. :^)
