  1. Velocity = Height (More or less) on Astronauts Pull Off Risky Spacewalk · · Score: 2, Informative
    The difference between physics on the ground and physics in orbit is really hard to 'show' without pictures... In orbit, everything's already moving forward (in this case, at 30,000 kilometers per hour), and being pulled downwards (in this case, at 9.8 meters per second per second.) Along with your current distance to the center of the Earth, these three things determine whether you're currently rising, falling, or staying the same. If you actually interested in learning all the formulas, this is, in fact, what the wiki's good for. Beginner , not-so-beginner , and freakin' huge! . I mean, hard. Yes, that's it.

    To sum it up, though, the total distance from the center of the orbited body and the orbiting object is proportional to the square of the velocity. Small change in velocity = not-quite so small, but still pretty small, change in orbital distance.

  2. Re:Rope to the rescue! on Astronauts Pull Off Risky Spacewalk · · Score: 1
    Do they have a long enough rope? I know they carry tethers for use with tools and such, but I don't know if those would be long enough, or strong enough, to make any difference...

    That does give me an amusing image, though. I can remember more than a few times I've dropped a nice new set of pliers in some ungodly-hard to reach spot on a job site. Can you imagine watching your 1200 dollar ultra-light weight tool set slowly floating past the window, a la 2001?

  3. Pretty hard push.... on Astronauts Pull Off Risky Spacewalk · · Score: 4, Informative
    There's no way a person could push hard enough to get themselves into atmosphere before they froze/suffocated. Everyhing up there is already moving at about 30,000 kilometers per hour - that's what sets their orbital distance at 350 km. Even assuming you pushed off hard enough to go 30 km/ hr relative to the station, that's still a total change of less than .1% in orbital momentum.

    It really doesn't matter what way you push off - down or 'back' (oppostite orbital direction), you end up going lower & slower, up or 'forward', higher & faster. You're still screwed, either way, but it won't be quick. (Well, unless you pop the suit open. That's quick.)

  4. Re:Truth is subjectivity? on When Wikipedia Fails · · Score: 1
    If there are no footnotes or a references section on a Wikipedia article, read the article with interest but don't trust it for anything.

    And if there are references, it's probably a good idea to check and see that they're actually quoted / paraphrased correctly.

    I think it's "sad" that "on the business end of the internet" companies like google can make large quantities of money purely on cult of personality, while not providing any value added to the user when it comes to simply searching the web.

    But if you go over to the cop/hooker and start rifling through her effects, even if she doesn't immediately try to stop you, and you take her wallet, that's not entrapment.

  12. Re:This is why I'm against organ transplants on Patient Revives After 19 Years By Rewiring Brain · · Score: 1
    Relating to the first point, that depends on what identity means to you. Believe it or not, there are at least 3 theories of identity and in two of those theories, who you are you, even if your personality and memories are different. Have a look at this short quiz for more info: http://www.philosophersnet.com/games/identity.htm . It actually covers a case that's very similar to the one provided.

    Okay, I took the quiz. Several times, I wanted to see what all the answers are... and in two out of three, I'd say letting go is the better option..

    1.)Psychological reductionism. - Suffering the kind of damage Mrs. Schiavo did, it's already all gone. Too late to save the self now.

    2.)Existence of a soul - Either it goes when the brain goes, or it hangs around trapped for a few decades. Either way....

    3.)Bodily continuity - I guess I would call this one genetic continuity.

    For the first case, you're already gone - survival of the body, with its new personality, would seem like kind of a moot point. The second case generally supposes some kind of afterlife - not any specific one, but generally religions with souls are religions with afterlives. The third case... I admit, that one I don't get.

    Considering that I was more making the comment that the 'belligerent nationalism' and 'social control' seemed to be some politicians goal of late, and yet the idea of economic controls in an anathema to the Republican party, your response is a bit overdone. But, like you said, this is slashdot, so go ahead and take everything personal.

    When a cop, dressed like a hooker, comes up to you and smiles pretty, and you offer her money, that's not entrapment.

    When a cop, dressed like a hooker, comes up to you and says, "Two hundred for the night", and you try to haggle, that is entrapment.

    Do you see the critical difference?

    Definition of Fascism: "A philosophy or system of government that is marked by stringent social and economic control, a strong, centralized government usually headed by a dictator, and often a policy of belligerent nationalism."

    That's it! As long as the economic controls are more akin to monkeys hitting buttons, they can't call us fascists! You, dear Mr. Thered, deserves an Iron Cross. I mean, a Presidential Medal of Freedom.

    I'm no lawyer, but, computer crime, like wire & mail fraud, is considered to have 'taken place' at end where the numbers get shifted around. So it doesn't matter where you are, it's the computer you're hacking into that determines the laws you have to follow. Kinda sucks, but such is life.

    While what you linked to is informative I don't designate it as indiscriminate since it is terrorists going after Americans who support abortion in some way. Islamic militants don't care about anything except that some of their targets have to be Americans.

    What part of only going after Americans isn't being discriminate?

    Non-pedantically, though, when one burns down a building that's part of a strip mall, and destroys several other buildings at the same time, that kinda starts pushing the bounds of being discriminate.

    If she'd had a living will or durable power of attorney, it wouldn't have happened.

    Depending on how explicit the will was, it probably still would have happened. The (intial) legal avenue the Schindler's appeals were based on was the fact that Mr. Schiavo publicly admitted to being in a relationship with another woman - they wanted to remove him as legal guardian.
