    (as it cools it contracts, when you melt it, it expands. think frozen water)

    You are incorrect sir; water and it's frozen form ice are the exception to the rule in this case.

    Water is at its densest at 4 degrees Celsius; below that, the dimagnetic structure of the molecules comes into play to form six-sided crystals that are actually less dense than the energetic but non-magnetically aligned water.

    This is why ice floats in water, instead of sinking. It's also why ponds don't freeze solid in the winter, and why we have no clue how to put someone into suspended animations and safely revive them yet.

    then maybe i should spread the word on how NewEgg fucked me on replacing my $600 digital camera and wouldn't return EVEN ONE of my e-mail contacts to them? (btw i originally heard about them through positive word of internet-mouth).

    $80 set of cylindrical speakers. Siluro's techno thingies, if you're interested. Bought from new egg. Open the box, and one of the speakers fell apart, the LED is hanging loose by one wire, and the spider on one of the drivers is broken.

    Had to pay to ship it back to NewEgg.

    That's $15 shipping both ways.

    And do they repair it and send it back?

    No, they refund my $80.

    So this christmas I spent $30 to learn that noone should ever buy from newegg ever. I am glad that it wasn't as costly to me as the lesson apparently was to you...

    But $1 would be too costly, IMHO...

  3. Re:Associated Press on Mine The Moon For Helium-3 · · Score: 1

    the only way that is possible is that the mass of the moon is in perfect balance with the distance it is from the earth and velocity that it is moving. if this was not perfect, it would have either floated away, or crashed into the earth years ago.

    Actually, the equations for orbital mechanics do not depend on the mass of the object orbiting. Just like gravity exerts the same acceleration on an object regardless of its mass.

    Now you can get a perturbation of an orbit, making it more elliptical, by changing its moment of inertia. However, the change would have to be very significant. Why? Because the moon-earth orbital system is stable for small perturbations.

    You can see that this is so on any night. Go out and look at the moon. See anything different? Of course not; the moon always shows the same face to earth. It is tidally locked; the effect of tides has caused the moon's rotation to become exactly equal to its orbital period. The same tidal forces tend to pull orbits into circles, which is why most of the larger bodies in the solar system have roughly circular orbits. The closer the body is, the larger this effect (it's an inverse-power law)... that's why the moon's orbit around the earth is nearly precisely circular, and why mercury's orbit around the sun is nearly precisely circular, but Pluto and Jupiter's farthest moons have very elliptical orbits.

    There are only a few factors that govern a body's orbit; mass of the object it is orbiting around, velocity, and distance. Given these three parameters, one can calculate its orbit very well. When the body in question is very massive, you have to run the calculation in reverse as well, meaning that the earth also orbits the moon. Actually, to be more precise, the earth and moon both orbit a point that is on a line between their centers of mass, the position of the point derived by their relative mass. In this case, that point is approximately 4000 mi away from Earth's center, putting it firmly within the crust. If you suddenly move mass from the moon to the earth, this point drops a bit more toward's the center of the Earth, with the effect that the moon will be a bit farther away from this center giving it a more elliptical orbit wrt Earth's center. But this new system is just as stable as the previous one.

    Basically, the formula for calculating orbits is indifferent to small perturbations. Slightly larger perturbations will be eroded away by tidal forces. Very much larger perturbations can cause the type of behaviour you're talking about, but if we have the energy surplus to make that kind of effect on the moon, what the hell are we doing mining He3 for energy?

  7. Re:Violence because of video games ? nahh on Army to use MMOG for Simulation Training · · Score: 1

    Your premise is wrong because you presume that violence is the desired end result, when in reality, the desired end result is soldier safety combined with an end to hostilities.

    Reminds me of Starship Troopers (the book, not the horribly inaccurate movie, horribly inaccurate even by Hollywood's loose standards)

    Early in the book, Rico makes a point that he and his teammates are there to provide violence. His commanders decide something needs to be done, to apply violence in a certain way, and it is his job to do it.

    Then he goes on about how modern war is not about killing your enemy; its about convincing him that you're right. Violence therefore is not a means to kill; in his kind of war, killing is the opposite of what you want. Your enemy has to be alive to be able to agree with you. He's philosophizing about this because he's on a mission on a planet of almost allies that humanity wants to be more firmly on their side. And therefore his mission is to avoid killing, but to decimate the infrastructure wherever possible.

    And then Rico says (paraphrasing), "I've never been asked to kill all the left-handed red heads in a certain area, but if someone decided it needed to be done, me and my men could do it."

    Maybe that's what this is about? After you've trained a soldier, after he has reached the point where physical exertion will never tire him again, after he has learned how to shoot as well as can be expected, operate the 200 or so different pieces of equipment he will run into as a soldier - operate them in the dark while sleeping nonetheless, and given him enough field training to ensure he can survive in a warzone...

    Maybe the next stage is to teach that soldier how to direct all this ability. The soldier has learned how to be violent. Maybe accelerated massively multi-user virtual reality simulations can provide the training necessary to control that violence, to channel it exactly where needed in exactly the amounts needed.

    Think about it; the key to learning any skill is practice and repetition. War games are all fine and good, but they take time to setup. They take time to play. They take time to get to and from. How long does it take for one war game? hours? days?

    What if you could run the soldier through the war game in only the time it takes for him to do his job? What if you could continually run him through it again and again, putting him in different situations each time, grading him, providing feedback? How many tactical situations could you put him through in the same time as the previous war game?

    While I was eyeing the recent flood of media players that hook up to the TV, I was also disappointed that just about every solution I find on the local shelves all require Windows 2000 or Windows XP.

    FYI, what used to be called QCast tuner (before GameShark bought them out) used a Java app, and was out of the box compatible with a variety of host systems.

    Cost is a little steep, though not overly so:

    PS2: $179
    Wireless Adapter: $59
    QCast Tuner: $50

    Total: $288

    Or about $90 more expensive than Gateway's similar product... though when you compare codecs, its apples to oranges... Gateway only supports MPEG 1/2/4

    The PS/2 supports that, DivX, and a few other codecs, not to mention a host of image and audio formats IIRC... also it is capable of supporting new codecs (it grabs the codec and saves it to the memory card)... though I've heard rumors that this is only the case with the QCast tuner, and that the new version does not do that...
