    And if they can think, doesn't that make them people?

    I think what the GP was getting at is that they don't have Tolkien's equivalent for "souls". I'm not saying anything about the existence of souls, but just commenting on my interpretation of GP's interpretation of Tolkien.

    Species is just an approximate categorization with no exact boundaries. The difference between strain or race and species is a matter of degree and convention.

  3. Just like Slashdot moderation on Censorship By Glut · · Score: 1

    Slashdot is a clear example of the Salganik effect. Watch as some random post gets modded +5 insightful, not because its any more insightful than the next post, but because some moderator gave it +1 and it just snowballed from there.

    You are only allowed to rate a song if you haven't looked at the current rating for the song. Ratings are only available after a threshold. Unfortunately, this means that you would be subject to listening to a lot of crap, if you want your opinion heard. Or, in Slashdot terms, you are only allowed to moderate responses in a story if you browse with moderation hidden.

    To be ethical, it's not sufficient to not do evil. You have to do good as well.

  6. Re:Mostly pointless on Benchmarks For Ubuntu vs. OpenSolaris vs. FreeBSD · · Score: 1

    That's the problem with all operating system benchmarks. You are essentially benchmarking the computer, not the OS. What really matters for an OS is how usable and efficient it is for getting things done. This means, of course, that the kernel is mostly irrelevant. The shell is what will influence how efficient a user can use it.

  7. Re:Did you read the page on that theory? on E=mc^2 Verified In Quantum Chromodynamic Calculation · · Score: 1
    It's not exactly right, but that doesn't mean it's wrong. Physics is all about approximations. We make an approximation, and then add perturbations to get closer to the right answer.

    100 standard deviations off is pretty damn good for an ab initio calculation. It suggests that the theory is on the right track, but missing some small terms.

    It's also valid if the "relativistic mass" is used for m.

  9. quantum mechanics + relativity on E=mc^2 Verified In Quantum Chromodynamic Calculation · · Score: 1
    This is wrong. There have been many successful combinations of quantum mechanics and special relativity. Quantum electrodynamics is such a combination, and tests of QED match experiment to extreme accuracy. Quantum chromodynamics is an adaptation to the strong force. The Dirac equation explains (to great accuracy) the fine structure of atoms.

    Rather, it's general relativity that is difficult to meld with quantum mechanics, but there has been some headway. String theories are such a construction. The only problem is that we don't know which, if any, string theory is correct.

  10. Re:I've only got one thing to say... on E=mc^2 Verified In Quantum Chromodynamic Calculation · · Score: 4, Informative
    Newton may have been incorrect, but Newton's laws are still basically correct, as long as you interpret it with a modern point of view.

    The first law defines an inertial reference frame, which should now be thought of as a free-falling frame.

    The second law is correct as long as you use the relativistic definition of momentum.

    The third law is still true in its original form. It basically says momentum is conserved.

  12. thermodynamics on Good Physics Books For a Math PhD Student? · · Score: 1
    Many of the PDEs in physics are fairly simple.

    The wave equation and diffusion equation are technically partial differential equations because of the 3 space dimensions and time, but these are simple PDEs because the three space dimensions are basically the same and the derivatives usually only appear as the Del operator, which treats each direction equally, and the boundary conditions are usually such that the constant of integration is just zero.

    In thermodynamics, you actually have serious PDEs which involve variables that aren't all the same, and the constant of integration must be found by matching arbitrary functions to each other and boundary conditions.

    This probably isn't a book for someone new to physics, but it does use some PDEs.

  13. Re:Halliday or Giancoli are nice on Good Physics Books For a Math PhD Student? · · Score: 1
    I don't recommend either Halliday/Resnick/Crane or Giancoli. They are both undergraduate texts treated at a rather simple level, light on math, and you'll never see a partial differential equation.

    That's the problem. Most texts that are basic physics also assume basic maths.

    Maybe you can handle Jackson Electrodynamics, which is a standard graduate level text. It won't be easy, but it doesn't really assume much foreknowledge, since it lays out the groundwork in the first few chapters (which are review for most students).

  14. Re:15kW is not very much. on Northrop Grumman Markets Weaponized Laser System · · Score: 3, Informative

    I guess you haven't worked with lasers much. A 3 Watt CO2 laser will burn paper in less than a second or so. Light bulbs put out a lot of power. If you hold on to a light bulb that's on, your hand won't last very long. Nevertheless, the destructive power is small compared to conventional weapons. The advantage here is accuracy.

    A desktop computer spends most of its time waiting for user input. If the OS or shell can elicit input and respond more quickly, it's faster.

    If you run a faster shell, you get more done, even if it takes just as long to calculate pi to 1 million digits.
