    Eugenics is junk science for four reasons:

    1) It makes invalid extrapolations from valid science.
    2) There is little empirical evidence for it, and what there is turns out to be tortuously misinterpreted.
    3) The validity or definition of some of its core concepts is questionable, so many of its ideas are untestable.
    4) It is statistically naive, ignoring things like regression to the mean.

    You can't extrapolate between dogs and people; dogs are domestic animals, and people are wild animals. At the risk of making another list, there are two problems with doing that:

    (A) Dogs are domestic animals; people are wild animals with far greater genetic diversity. Sexual reproduction is supposed to increase genetic diversity; only by starting with an artificially uniform genetic population can you breed for specific traits with any reliability. Look at several large human families and while you'll see some resemblance, it's far less than the resemblance of purebred puppies born in the same litter.

    (B) A dog reaches sexual maturity in 6-12 months; humans in 12-14 years. In the course of a 40 career a dog breeder gets to work with 30-50 generations, a human breeder would only get 2-3. Even if you start by inbreeding a single human family, it'll take you centuries to get the kind of results a dog breeder can get in 20 years.

    Yes, the authors have managed to write a sentence that is incomprehensible to people who understand electronics and people who don't, but for different reasons.

    Let me plays devil's advocate, though, and construe a speculative interpretation that might make sense.

    This thing generates plasma -- from what? Probably the air. So my guess is that it applies a pulse of high voltage to ionize the air, producing a plasma. Now suppose the plasma is too hot, what would adding a resistor in series do?

    Well, a resistance value could be chosen so high that if you *shorted* the air gap, the resistor itself would dissipate negligible power, yet that value could still be negligible compared to the resistance of an un-ionized [note 1] air gap. This would greatly limit the power dissipated by the arc (especially given that the arc's resistance *decreases* as the current flowing through it increases), while posing no barrier to the formation of the arc in the first place.

    note 1: air can be ionized or not, but I have no idea whether it can unionize.

  11. Re:Real science, please on Battery-Powered Plasma Flashlight Makes Short Work of Bacteria · · Score: 3, Informative

    No, because resistors generate heat when current flows through them.

    Yes, but that doesn't necessarily mean the total heat dissipated increases. If you have a constant voltage supply (typical), adding a resistor in *series* with the load *reduces* the total power dissipated. Yes, the resistor generates heat, but that is more than offset by a reduction in the heat generated by the load.

    If a resistor in series with the load reduces the current by 1/2, the power dissipated by the load is reduced to 1/4 what it would be without the load.

    Constant voltage is the most common case, as it is supplied by outlets and batteries, but some power supplies provide constant current, in which case adding a resistor in series would not alter the load power dissipation, and (as you are asserting) the heat generated by the resistor would add to the net heat dissipation.

    Supposing you're driving an LED (disclaimer, I am not an LED lighting engineer), you'd want to keep it in the correct current range, so you'd use a constant current power supply. If you put a second identical LED in series with the first, you'd double the load resistance [note 1], but the power supply's voltage would adjust so the current remains the same. The Captain Obvious result is that if you drive 2 serially connected LEDs off your constant current supply instead of 1, the power dissipated doubles. The somewhat less obvious result is that if you're using a constant voltage supply the total power dissipated drops, so the the power dissipated by each of the two LEDs is less than one half what a single LED would.

    note 1: LEDs aren't linear in their response like a plain resistor, so this wouldn't necessarily be true if we were talking about a constant voltage supply like a battery.

  12. Re:Club of Rome Study 2 on MIT Institute's Gloomy Prediction: 'Global Economic Collapse' By 2030 · · Score: 1

    Well, to play devil's advocate, the universe doesn't owe us a living. Species go extinct, societies and nations collapse; it's a fair bet our species will go extinct and our society will collapse some day. The trick is predicting *when*.

    The problem with trying to put a date on it is all the "ceteris paribus" assumptions, the way we assume that things won't change. One consistent problem with Malthusian predictions is the assumption that agricultural productivity won't change. Historically it always has, but we can't count on that *indefinitely*. There are thermodynamic limits to how much food energy you can get out of an acre of land, although we aren't close to them yet.

    The approach to a limit is not necessarily a disaster. There are three possible results: (1) the limit is relaxed; (2) soft landing, (3) hard landing. Because of the economics of consumption, the soft/hard landing depends on how suddenly we reach the limit. If we approach slowly there is more time for innovation and for people to moderate their consumption. So far the big gains agriculturally have come from relaxing limits, but you can't count on that happening, any more than you can count on it *not* happening. Certainly it argues for the importance of applied research whose potential returns are outside the range of normal business research investments.

    Idiot Malthusians have predicted the imminent end of the world due to overpopulation for hundreds of years.

    It has been 214 years since the publication of Malthus' "An Essay on the Principle of Population". That isn't a very long time, it roughly coincides with the start of the Industrial Revolution. Let's use the IR as the benchmark of our society's staying power.

    Suppose you are Rome in the year 10CE. Your city has existed for five hundred years as a Republic, and about 40 years under the wise and moderate Augustus. You'd have plenty of reason to feel smug about the stability of your society, little suspecting that four years later you were going to be ruled by paranoid Tiberius and after him *Caligula*. The particular kid of rot that set in with Rome allowed it to chug along for a few more centuries, but the future was hardly the golden age you'd expect.

    No, that's freedom from prior restraint. It's part of the overall concept of free speech, but not the totality of it.

    I understand that, but it's really the important bit. No concept of free speech works without freedom from prior restraint, and any concept of free speech that includes freedom from prior restraint can work, if people are willing to risk standing up to the government.

    Freedom of Speech is poorly defined, but it generally means that you can say what you want, apart from a few specifically defined instances. Think of it as "default allow" for speech. Basically, if there are no laws against what you are saying, then the government can't punish you for saying it.

    Unfortunately that's not much of a guide to what's allowed. To say something is allowed if it is not denied is logically equivalent to saying it's denied if it is not allowed. It'd be more precise to say that speech is allowed unless it does unreasonable harm or the government has a legitimate interest in restricting that speech. Unfortunately, you're still stuck with deciding what is "reasonable" or "legitimate".

    In the end it boils with what people will put up with provided (and this is important) everything is out on the table. When the Pentagon Papers were published, they were top secret. The documents that showed the government had been lying to the American people about what it was up to in Vietnam, had expanded the war in various questionably Constitutional ways, and was continuing the war mainly to avoid the political embarrassment of defeat, rather than for any substantive national interest. Disclosing top secret documents is a felony, but once the government lost its bid to impose prior restraint, it was unable to mount a successful prosecution of the men responsible for the leak. They couldn't drop frightening hints about damage to national interests because what the Pentagon Papers revealed that national interests played almost no role in the continuation of the war. Any argument that the leak put troops in harm's way would have been ironic given that at the time the leak occurred US forces were suffering 45 casualties/week for no identifiable national purpose.
