    Which just goes to show the moderators either don't read or don't agree with the guidelines.

    No, it goes to show what people will do for a cheap +5 informative. Why did the GGP post as a reply to the flame? To be at the top of the page. And what did his link to the 300+ planets have anything to do with TFA? That's a planet, these are planets, +5 Informative in no time!

    I'm all for voting things up rather than down, but in cases like this, the entire thread needs to be modded to oblivion.

    Agreed.

    This must be the first Slashdot post with a GNAA subject line that's been modded "informative" in years.

    That's because all the new heres thought GNAA is the crossover interest organization of their dreams: the GNU Astronomy Association.

    Thank you, I did not know about the Abbe number. In the physics classes that I had taken, we had never encountered that. I do appreciate the fix.

    Yes, but you know that. The current disposable tech responsible for tens of federal servers may not know what is in each and every one of them.

    1) next to impossible != impossible
    2) if the feds require multi-pass wipes for non-classified data and media destruction for classified data, why should I settle for anything less?

    Because the feds may very well still be using drives from an era where /dev/zero was not enough to erase the drive completely. Furthermore, the feds may not trust their techs to decide which drives can and which drives cannot be wiped as such.

    Furthermore, the feds don't care about donating their equipment to the needy. Every donation center has a surplus of harddriveless computers. They all need harddrives.

    Its funny how you are so pendantic yet so wrong. C is not the speed of light in a vacuum. You are thinking of c.

    You are right, I choose to use the capital as I was beginning the sentence with it. Thanks.

  10. Re:wavelength = length on A Step Toward an Invisibility Cloak · · Score: 1

    Th refractive index of the material does _not_ depend on the frequency of the light wave, even though different frequencies refract at different angles (think prism). The refractive index depends upon the molecular structure of the material (and temperature to a point). Then, precise refraction can be calculated based upon the refractive index of the entering material, the exit material, and the frequency.

    Why would that be no longer effective? If the cloak reroutes 90% of the light, then you're left with 10% opacity, right? Sure, something that translucent would be very difficult to see, especially from a distance.

    The Predator still got his ass shot up good with that hand-held vulcan gun, because the soldier saw the 10% of light that he couldn't cloak.

    I knew of an African Grey that would say things like "Chaz, don't smoke!" or "Chaz, don't hit your brother!". It annoyed Chaz as much as it made his mother's life easier.

    The deeper we look the more layers we find. It's like finding out that your Commodore-64 is really an 8086-PC emulating the C64, but that the 8086 is really a 286 emulating the 8086. But the 286 is really a 386 emulating a 286, which is really a Pentium emulating a 386 emulating a 286 emulating a 8086 emulating a C64, and new evidence suggests that the Pentium is being emulated also.

    Mathematical regression is also an example of this: the regression formulas can be made to model almost any continuous curve if you throw enough terms into them. However, that does not mean that the resulting equation in any way matches the mechanism that generated the actual curve.

    That is already known to be the case. We call those particles "atoms", which are much larger than the Plank scale and so off limits here. This article refers to sub-subatomic particle structures.
