  1. Re:Score one for The Gipper - yet again. on Laser Weapon Shoots Down Airplanes In Test · · Score: 1

    No concievable missile shield could shoot down any significant number of incoming missiles. The Russians would always be able to overwhelm the defenses with shear numbers, making the system worthless.

    Even if that's true, it makes the system worthless only if your sole benchmark is "does it make us invulnerable to any hostile ICBM force, no matter how large?" But that isn't the only goal. First, there is a defense against a limited strike from a less-powerful adversary. Second, it makes it much, much more difficult to wipe out our ICBM force in a surprise attack and thus remain safe from retaliation. The odds of a given target surviving do not scale linearly with the number of attacking missiles. Consider (using round numbers for simplicity) that we have 1000 ICBMs, and a defense system with a 50/50 chance of shooting down an incoming missile.

    • Prior to having the defense, an enemy surprise attack can destroy our force on the ground using 1000 missiles (leaving aside factors like mechanical failure).
    • After we put in the defense, such an attack would destroy only 500 of our missiles, leaving us with 500 to retaliate with, far more than enough for a devastating return strike, given that we wouldn't need to bother attacking now-empty silos.
    • Suppose that the enemy decides to use twice as many missiles. That means that the odds of any given one of ours surviving is 0.5^2, or 25%. They attack with 2000 missiles. 250 of ours survive, still too much for any country to absorb and continue to effectively exist.
    • They decide to use three times as many. 0.5^3 = 12.5%, so 125 of ours survive to strike back. Still enough to wipe out a majority of the biggest country's military. If this were Russia we were talking about, their reward for destroying our ICBM force would probably be getting conquered by China.
    • 4000 missiles are used. 0.5^4 = 6.25%. Losing 62 major military/industrial assets at once probably wouldn't eliminate a Russia-sized country as a cohesive entity, but they're not going to be invading anyone for a long time, and they're going to have chunks of their territory gobbled up by their neighbors. If they consider getting hit by 50 acceptable, they need to attack with 4322. Down to 10, they need 6643. To get it below 0.5 (i.e. to have the odds favor getting off unscathed) they need 10,965.
    • That's just against a poorly-performing defense. Suppose we have a 90% intercept rate. They need to attack with 28,433 (instead of 4322) missiles to get keep their losses below 50 targets. If we get it to 99%, they need 298,072.

    To sum up after all the numbers: against even a minimally-effective missile defense, it becomes extremely costly for an attacker to field a force big enough for him to strike and wind up in a better strategic position than he started with, which is the whole point of attacking in the first place. As the defense becomes more effective, doing so becomes well-nigh impossible.

    Are you all slaves for the corporations or whatever organization pays your salaries? Is that the only lens through which you can see the world?

    Oh, please. Most corporations don't give a damn about government policies that don't visibly impact them. I highly doubt the upper management of my employer (a software/hardware company) would care what I said about government press funding one way or another. You're basically espousing the Marxist idea of "class interest" (not that I'm calling you a Marxist), the belief that people act to further their perceived interests as "workers" or "the rich" or whatever -- in your case, "corporation" being an equivalent of a "class." Which is, of course, why Larry Ellison and Bill Gates got along so well, and why Apple and Google are in such agreement.

    Actually, now that I think about it, my employer would probably prefer a government-funded press. Our biggest customers are Las Vegas casinos. As the major tax base in Nevada they definitely get listened to by politicians, all the way up to Harry Reid, the Senate majority leader. I'm sure if some news story came along that would hurt the casinos, they'd love to be able to ask Senator Reid to drop a pointed hint to the right people about not covering the story (can't have reporters wasting tax money on something that's "not newsworthy" after all), and what's good for my employer's customers is good for my employer.

    Most words have multiple definitions, and those definitions are for the most part determined by common usage. In the lack of a specific context, when someone uses a word, listeners assume he means the most common definition. The word used to denote a citizen of the United States is "American" both because that's the word people usually use for that purpose and because that's the purpose for which people usually use that word. I have co-workers who come from Bangalore in the Republic of India. Should I start referring to them as "RoIians" so as not to offend citizens of Pakistan and Bangladesh, both of which are located on the Indian subcontinent?

    It only underlines my point, as to the self-centred, narcissistic attitudes of the citizens of the USA that they would claim a continent-wide description for themselves exclusively and not bat an eye at this. I used "USian" here as a shortcut, because it is more precise.

    Yes. Why not? If a government has the power to ban beliefs, it has the power to ban belief in the truth. In fact, with the right person interpreting the rules, hate speech laws could just as easily ban acknowledging the Holocaust as a racist slander against poor innocent Germans.

    You have to draw the line somewhere.

    That line exists where speech becomes planning towards specific acts (see above). Otherwise, as others have noted in this discussion, it's a sticks-and-stones vs. words distinction.

    And I am not saying that I should decide what that line is

    But that's exactly the issue: someone will be drawing that line, and you have no idea to what extent that person will share your intent. Someone will be deciding, in each case, whether the speech in question is "hate speech." You can make whatever rules or guidelines you want, but in the end someone must interpret them. Now, imagine that person is someone 180-degrees from you politically. If you're liberal, pick Michael Savage. If you're conservative, pick Michael Moore. Now craft your "hate speech" definition such that the chosen person won't be able to twist it into something that makes you weep.

    , or exactly where it lies, but I do feel that we should always keep having the discussion on where to draw the line. Just because you *can* say anything you like, it doesn't mean that you should.

    True as far as it goes, but beside the point. Laws are about "must" or "must not"; matters of "should" or "should not" are outside their scope. Arrests of homicide suspects aren't based on laws that say "murder isn't a good idea."

    The folks pushing this don't want the labels so that they can avoid cloned meat. Anyone who really cares about it can buy from sources that target them (fx. the Trader Joe's chain). What they are interested in is making the average non-caring consumer think that there's something wrong with cloned meat, since there's what appears to be a warning label on it, and thus deter producers from using cloning.

    That the FDA is set to allow sale of cloned meat without special labelling means that they've determined that it's not a distinction pertinent to anyone's health. That makes it the secular equivalent of a religious dietary restriction. The costs associated with making sure that the meat in a package isn't cloned should fall on those who care about it, not those who don't. If enough people do want badly enough to avoid cloned meat, specialty stores and sections within stores will cater to that. But it's not a health concern, so it shouldn't be depicted as such on the label. There are "contains nuts" labels because people can have serious allergic reactions to them. But there aren't big red "Warning! Not Kosher!" and "Not Halal!" labels on ham, nor "Contains Beef!" or "Contains Caffeine!" stickers on sausages and energy drinks despite devout Jews, Muslims, Hindus and Mormons not wanting to consume those things. Orthodox Jews pay a premium for kosher products, since they're the ones to whom it matters. So do people who want organic produce or "fair trade" coffee.

Rods (monochromatic) are more sensitive and work in low light, whereas cones (color) require brighter light. If you replace the cones with rods, you get an eye that's more sensitive (hence detects motion better) and works better in darkness, but can no longer see in color. Going from monochromatic to color nightvision gear wouldn't reduce a human's ability to detect motion, because the number of rod cells in their retina would remain the same.

It's a war that's been going on, at a lower level of intensity, for quite a while -- the recent phase having begun in 1979. 9/11 was merely the first time something happened where people couldn't ignore it, and the Middle East military operations under Bush just the first time the US has attempted (whether you agree with how he's conducted it or not) to actually do something about it. It's going to continue, whether we try to influence the outcome or not, and the US will be a target.
