  1. Re:One thing I *NEVER* see ... on SpaceShipThree to be Orbital Spacecraft · · Score: 1
    An orbiting object's energy is one half kinetic energy, one half potential energy, and so slowing down to zero orbital speed relative to the atmosphere still leaves you with 50% of your energy to burn off.
    And you could obviously use a rocket to get rid of both. It should be straightforward to plot a powered descent trajectory that gets you to the stratosphere with minimal heating.
  2. Re:Another Idea. on SpaceShipThree to be Orbital Spacecraft · · Score: 1
    The nuclear plasma engines solve this problem by creating hydrogen plasma at very high velocities and are quite efficient. But the radiation shielding needed to make the crew survive negates the advantages on manned spacecraft.
    This is not at all obvious.
  3. Re:My whacky idea for re-entry on SpaceShipThree to be Orbital Spacecraft · · Score: 1

    Think about the mechanics a bit. The spacecraft will be quickly pulled right down into the atmosphere ahead of the anchor.

    Besides, your cable will melt. If there was anything it could be made of that would withstand the heat you'd just make the spacecraft out of it.

    It will no doubt come as a great shock to you to learn that your local Baptist fundamentalism is not the only religion in the world.

    Speak for your self.

  6. Re:Not quite on Scientists Speed up Light · · Score: 1

    And parts of the information superhighway is made up of electrons ambling down a wire at speeds very much below c.


    Except that the signal in a wire travels quite a bit faster than the electrons (though still slower than c).
  7. Thin Edge on New Technique for Creating Nanotube Sheets · · Score: 1

    The name of the material you are looking for is "thin edge". It comes from an Analog story of the same name published, I believe, in the 1970s.

  8. Re:Functional Psychopaths on Is Your Boss a Psychopath? · · Score: 1
    I believe the inventory referred to in this article simply tests for psychopathic traits, or at least their appearance.
    No. It merely tests whether the person doing the inventory dislikes the person being inventoried.
  9. Don't Forget The Background Check on Is Your Boss a Psychopath? · · Score: 1
    Why not [screen] people who are going to handle billions of dollars?.
    Why not screen everyone?
    The same source also has a quiz (magazine produced it seems) which allows you to test your own boss, too!
    Don't forget to test yourself.
  10. Re:Not a matter for the law on Virtual Muggings in Lineage II · · Score: 1
    If somebody cheated at poker to take things of value, that would be a crime.
    These people were not playing for things of real value.
  11. Re:Where the fault lies... on Virtual Muggings in Lineage II · · Score: 1
    But I also know that if somebody stole money from me, I can expect the police to do something about it.
    That's real money in the real world. We're talking about a guy who cheated at a game to get imaginary stuff.
    But he did cross that line from virtual crime to real world crime, and now he must face the courts.
    The only courts that should be involved should be the civil courts. I can see the game operators suing the miscreant for breach of contract and perhaps the "victim" suing the operators but involving criminal law is ridiculous. No one was injured and no one was deprived of any non-imaginary property.

    Not without buying Sun first.

    > ...in the many areas where Solaris is miles

    After all, it's not as if Linux had the backing of a major computer company with a three letter name.

    Oh. Wait...

  14. Re:MOD PARENT UP (... please ...) on Businesses To Be Censored on Use of Olympics · · Score: 1

    That may be true of professionals such as those in the Olympics, but there are amateurs who don't use drugs.

  15. Re:Already in the US on Businesses To Be Censored on Use of Olympics · · Score: 1

    The US law is not anywhere near as drastic as this UK one (though I'm sure it would be if they could get away with it).

    Yes. They will. The senators will want to know what new laws Microsoft needs in order to better control the "hackers" that are behind all this. To politicians "improved security" means more laws and more cops.

  17. Re:Nice little girl. on Warming Up Mars With Greenhouse Gases · · Score: 1

    You're the one who didn't think it through. It would take millions of years for enough gas to escape to matter.

    And it isn't to blame for global warming: there isn't enough of it released to matter. CO2 is to blame for global warming.

    That won't work in the US. If the object I am offering for sale says "Sony PSP" on it I can say so (not that they might not sue anyway, just for harrassment).

    It's a joke, son. I'm humorously suggesting that the men in the black helicopters have developed (or stolen it from aliens) this technology to the point of not needing seven tesla magnets.
