    There are two canonical limits on assassination as a means of political expression: retaliation and the death of the assassin. Retaliation (if you assassinate our leader we'll assassinate yours) doesn't apply to terrorist groups, but presumably the ability of suicide bombers to get close to political leaders is poor enough that for the most part we see them being deployed against soft targets. That is, there are crazy people willing to blow themselves up to kill innocents, but not very many crazy people willing to bet on long odds to kill political leaders. The average political assassin will die (or get caught) without killing their victim, and apparently even nutjobs don't think that's a good trade-off.

When its a machine, you can just scrub the logs, scrap the device, and claim that an unpredictable hardware failure resulted in the peaceful protestors being gunned down.

    Killer robots, like machines that kill generally, are a stupid idea, and engineers who work on them should be ashamed of themselves.

    Aristotle's physics was based on exactly the kind of informal observation and narrative reasoning you are deploying here. If you reject the utility of Aristotelian physics, you need to explain why you do not reject your own reasoning in this case. It's a serious question, and there is no doubt the discipline of science is really, really hard.

    Most people can't practice the discipline of science: their anecdotal, narrative cloaking of reality is too powerful and comfortable, and stripping it away makes them feel vulnerable and uncomfortable. But for those few of us who can, in the end it's worth it, because it allows us to create solutions to problems that actually work, rather than pursuing policies that have failed before and will fail again.

    You've really posed a political question, which is what "philosophical questions" become when anyone cares about them.

    "What abstract category shall we put this concrete reality in" only matters to people who think abstractions exist independently of knowing subjects, which is say, idiots.

    Nothing "is" a "failure" or a "success". Things actively assigned to the categories failure and success by knowing subjects. The act of assignment is useful. It reduces the extreme cognitive burden we face when thinking about more than five or ten things. But when we turn around and treat those categories as more than cognitive conveniences, and therefore treat it as a matter of import which one we assign a concrete reality to, we are almost always engaged in some kind of political act.

  13. Gold Standard? on Why P-values Cannot Tell You If a Hypothesis Is Correct · · Score: 4, Interesting

    That means "outmoded and archaic", right?

    I realize I have a p-value in my .sig line and have for a decade, but p-values were a mediocre way to communicate the plausibility of a claim even in 2003. They are still used simply because the scientific community--and even moreso the research communities in some areas of the social sciences--are incredibly conservative and unwilling to update their standards of practice long after the rest of the world has passed them by.

    Everyone who cares about epistemology has known for decades that p-values are a lousy way to communicate (im)plausibility. This is part and parcel of the Bayesian revolution. It's good that Nature is finally noticing, but it's not as if papers haven't been published in ApJ and similar journals since the '90's with curves showing the plausibility of hypotheses as positive statements.

    A p-value is the probability of the data occurring given the null hypothesis is true, and which in the strictest sense says nothing about the hypothesis under test, only the null. This is why the value cited in my .sig line is relevant: people who are innocent are not guilty. This rare case where there is an interesting binary opposition between competing hypothesis is the only one where p-values are modestly useful.

    In the general case there are multiple competing hypotheses, and Bayesian analysis is well-suited to updating their plausiblities given some new evidence (I'm personally in favour of biased priors as well.) The results of such an analysis is the plausibility of each hypothesis given everything we know, which is the most anyone can ever reasonably hope for in our quest to know the world.

    [Note on language: I distinguish between "plausibility"--which is the degree of belief we have in something--and "probability"--which I'm comfortable taking on a more-or-less frequentist basis. Many Bayesians use "probability" for both of these related by distinct concepts, which I believe is a source of a great deal of confusion, particularly around the question of subjectivity. Plausibilities are subjective, probabilities are objective.]

    That no libertarian anywhere is actually opposed to oppression by legally-privileged corporations tells you they are either a) ignorant or b) dishonest. I was an ignorant libertarian for many years, so I know whereof I speak.

    To be absolutely clear on this: corporations are legally privileged by very specific legislative intervention into markets. These legal privileges are generally encoded in something called the "Companies Act" or the like, and derive from the original Companies Act reforms that occurred in Britain in the mid-1800's that gave birth to the modern corporation to which we owe so much in terms of wealth.

    Adam Smith opposed corporations because he opposed Nanny State interference in free markets, but he didn't appreciate the huge benefits the corporate form of organization could yield. Unfortunately, like fire and governments, corporations are powerful servants and dangerous masters, and we have reached a point where the corporate wild-fire is well and truly out of control, in part thanks to "libertarians" who either don't understand markets or choose to falsely claim that corporations are not legally privileged forms of collective organization.

    The theory they are based on, curiously, predicts that they are free in the medium they exist in, which was something of a surprise. That is, in an infinite BEC, they would be free to move anywhere, making them much more like "true" monopoles than expected.

    Whether or not you call these "real" monopoles is a matter of taste. The reality is that at sufficiently large distances no experiment you could perform would be able to distinguish them from a monopole particle, making them extremely practical mechanisms for investigating the physics of monopoles.

    One interesting thing is that Dirac showed the existence of a single monopole anywhere in the universe could explain why the electron charge was quantized, because for a given monopole strength there is only one value of electron charge that can interact with it consistently (any other value requires the electron wavefunction to have multiple values at same point in space-time, which would imply a breakdown of quantum mechanics.) I don't know if these pseudo-monopoles are sufficient to impose that condition.

I know people who can't go below on a relatively calm day without turning green and losing their lunch, and I know people who have cast-iron stomachs. There are enough of the latter about that it is unlikely we'll need to build truly huge structures for long-term space flight.

It has a warm interior, with a thermal gradient near the surface that might well power molecular machines.

    Also, Ceres orbits at just under 3 AU, so the solar flux on its surface is about 10% of what we get on Earth, which would make the integrated solar flux comparable to what is seen on Earth at about 55 degrees latitude in winter, well below the (ant)arctic circle.
