Scientists Create Supersolid From Helium

jabberjaw writes "Nature is reporting that Pennsylvania State University researchers Eun-Seong Kim and Moses Chan have created a 'supersolid' from helium-4. Although a crystalline solid, the supersolid can flow much like a liquid. This is due to the fact that the empty compartments in the crystal move coherently, thus waves can progress through the lattice. The supersolid state can be compared to the superfluid state. Perhaps a condensed matter physicist can dumb the article down for layfolk such as myself?"

    Not only is it lighter than air, it can be condensed into this condensate which can in turn be used as a coolant for modern PC CPUs.

    Also, since it is inflammable, helium is safer than trying to use something like liquid hydrogen or liquid peroxide as an intercooler fluid.

    Why is it that otherwise intelligent people can't get their heads round spelling simple words? Or are unable to differentiate between two similarly spelt (yes, spelt, not spelled) words that have different meanings?

    If you don't know the difference between a "principle" and a "principal" then go find out. On principle, I won't spoonfeed you with relevant links; you can go do the legwork yourself for once.

    Perhaps a condensed matter physicist can dumb the article down for layfolk such as myself?"

    When are you doofuses going to figure out that "myself" is only an appropriate pronoun for an referent of "I" or "me"? That's why it's called reflexive. For comparison, consider how stupid this sounds: "Audrey can speak to myself on the telephone."

    People who can't figure out whether to use "I" or "me" would do well to avoid falling back on "myself". At least if you stick with "me" or "I" you have a chance of being correct. This "myself" nonsense has become plague of bad usage in the last year or so.

    BTW, you could have avoided the I/me confusion entirely by simply writing "Perhaps a condensed matter physicist can dumb the article down for us layfolk."

    For what it's worth, though you're mostly correct, it's a falsehood, not a fallacy. A falsehood is a piece of incorrect information - a myth, a popular misconception, a lie. A fallacy is a conclusion reached from information (whether or not the information is correct is unimportant) where the reasoning suffers a flaw.

    Examples:

    "Rubenstein's paper shows that white men named
    Tim have three arms." Falsehood: there is no
    such paper.

    "John Q. Scientist agrees with me, so I'm
    right." Fallacy: appeal to authority
    (argumentum ad verecundiam.)

    "4=5." Falsehood.

    "Because 4=5, and because in a=b a*c=b*c, then
    8=10." Falsehood. The reasoning is correct,
    but the underlying information is in error.

    "Because a*c=b*c and a+c=b+c, then for any
    operator ?, a?c=b?c" Fallacy: operators do
    not have the same rules, so you may not infer
    rules by commonality (Accident, Hasty
    Generalization)

    "Because 4=5, and because a?c=b?c,
    then 4*2=5*2, so 8=10." Both a fallacy and a
    falsehood. I duplicated the above example to
    demonstrate that a fallacy can lead to
    seemingly correct reasoning. I stuck with the
    falsehood to show that fallacious reasoning
    which leads to correct reasoning isn't
    therefore somehow absolved; it's still a
    falsehood.

    "Because 1=1, and because a?c=b?c, then
    1*2=1*2, or 2=2." A fallacy can in fact lead
    to both seemingly good reasoning and seemingly
    correct results. Frequently, someone will
    attempt a bait and switch, using a cursory
    example like this which fails to display a
    flaw in reasoning to try to establish said
    reasoning as correct, and then lead into the
    incorrect results. How many times have you
    heard, in moral rather than mathematical
    context, something like "you wouldn't
    challenge that 2=2, would you? or that
    1*2+3*2=4*2? or that 3*2=1*2+2*2? so then
    if 3^2 + 4^2 = 5^2, then clearly 3+4=5. how
    can you challenge that?" That is argument by
    generalization, and frequently includes
    unrepresentative samples, false analogies,
    and fallacies of exclusion.

    Sorry about the pedantry; I just hate to see people call things fallacies or falsehoods which aren't.
