    Actually that's a rather recent development. I remember all the fanfare when they installed the system and thinking to myself, "Wait.. that's NEW?" That's what I got for assuming NASA has PHB teambuilding exercise ropes course technology.

    Good points all, but not quite correct. Orbital mechanics is screwy. If you push off forwards, you go higher, but you actually have less angular velocity in the higher orbit, so the thing you pushed off from will pass you. If you push off backwards, the opposite happens. Pushing up or down also doesn't do what you'd expect.

    Actually, it's both "ape faith" and "human faith." All the axioms are like that. They're the fundamental "first principles" from which everything else is derived. We believe they are the basic laws of the universe, but of course we don't discount the possibility that further research will reveal what we think are the first principles are actually consequences of other more basic laws.

    Yes, it's true that there are TWO sins here: one is the government for requiring many services (who should pay for 911 for instance..) rather than purchasing them like normal entities. The other is the phone company for not folding costs of doing business into their advertised price.

    Someone failed econ.

    If you expand the pool of potential CEOs, you have increased the supply. The number of companies that need CEOs is small compared to the number of business school graduates, so the price will fall to market clearing levels. The thing that maintains CEO salaries at their current level is the apparantly popular meme of the 'corporate savior' which effectively reduces the labor pool.

    Compare to another market, say.. Diamond trade. diamonds aren't even really all that valuable. They are a middling semi-precious stone. Look at the market for non-gem cut natural or industrial diamonds or the secondary market for diamonds. The perception that a NEW, gem-cut natural diamonds are somehow better keeps the price up by encouraging demand for a specific, limited-supply commodity.

    The analogy is particulaly apt, since artificial diamonds can be made even purer than their "more valuable" natural counterparts. The value a result of a clever advertising campaign.

    Though to be fair, one of the goals of any advertising campagn is to increase the percieved value of your product so as to command a higher price. It is up to the consumer to see through the hype and recognize the real value of the product they're buying. Caveat emptor.

  12. Phone bill. on OfficeMax Drops Mail-in Rebates · · Score: 1

    Call your phone company. Those charges aren't taxes. They are passing on the cost of mandated services as separate items in your bill instead of folding them into the price like normal businesses do with costs of doing business. It is unfortunate that ALL of the phone companies do this, so you're stuck. Seems there is a bit of a market failure going on here.

    Incorrect. L1-3 work like that for in-plane perturbations, but nearly-stable orbits can be designed for them using minimal propellent. see SOHO for the textbook example. L4 and L5 are stable. The problem there is accumulation of dust. One wonders why the article said they'd be protected from insolation though, since L4,5 are 60 degrees ahead and behind the earth.

    It's pretty clear from the article that the files were stored on the desktop, not "my documents." presumably for easier access. I'm pretty sure it takes a more than zero amount of tech knowledge to realize that you can put stuff there instead of the default location. I realize it's often the default location for downloaded files, but that wouldn't go in the writer's favor..

    Clearly the techie thought he was doing the guy a favor by cleaning up his desktop. Heck, I do this for my friends and family when they ask me to fix their computers up. Of course, I just move stuff into a folder, since I don't know how valuable it really is to them, but I can see how a nitwit could delete things without realizing they're not garbage. Especially if the dimbulb in question was used to a network environment where the size of the user's desktop profile affects the login time.

    OTOH, suppose the technician read the scripts and figgured that the favor he'd do the world by destroying them was well worth losing his job over...

  19. Re:Just out of curiosity... on The Physics of Superman · · Score: 2, Interesting

    The problems are,

    accleration gradient - you don't want very much of one or your balance will be all screwy.
    coriolis "force" - a result of the transformation to a rotating reference frame. You want to minimize this as well, for balance reasons.

    Fortunately the solution to both is to increase R. Unfortunately, this limits where you can place your rotating habitat and increase the cost to power it.

    So some practical numbers: (i'm not sure how to do the coriolis part, but the rest is pretty easy)

    Suppose we took the land for the cancelled superconductiong supercollider in Texas. It had a radus of approximately 14 km. To get a net force of 2g, we need a rotational acceleration of 1.73g, since we already have gravity working for us. So you'd need to have a tangential velocity of 350 mph. The difference in acceleration between your head and your feet would be of the order 2e-5 g, so I don't think you'd notice much.

    Perhaps if your habitat was a well-lubricated train you could do it. Certainly there have been very fast electric trains before, and over much longer distances than an 80 mile circuit. I would suggest a hanging monorail design so you could achieve multiple accelerations without having to completely redesign the bank angle every time.

    Everyone thinks their second language is better than their first at some point in their studies. It's because of their less intuitive learning process: you learn more of the "whys" directly rather than through imitation and implication during your formative years.

    But there really is no best language. Every one has advantages and disadvantages that are more or less important depending on the concept you're trying to express. In fact, there really is no single language that performs all of these tasks when you consider the largely orthogonal jargon used by the various professionals within a culture. Aerospace engineers and medical doctors for instance use separate enough language that they could almost be considered to be speaking entirely different languages.

    reread.

    not every lethal weapon needs to actually do anything at all to be effective. For instance, only two nuclear bombs have ever been dropped in anger. Since, thousands have been manufactured whose primary purpose is, in fact, not to be fired. Which bombs have had more effect on the world stage do you think, the ones that were dropped or the ones that weren't?
