    160'000 are permanently disabled.

    If they had symptoms that are actually caused by radiation exposure that would be a matter of concern. My only question is what has disabled 160,000 people? Since radiation exposure does not disable people, there must be something else going on.

    The NRC generally recognizes a zero-threshold proportional model for long-term risk from exposure.

    Which is completely unsupported by any of the science of radiation exposure, either in terms of low-dose chronic exposure (people who live at high altitudes) or in terms of what we know about radiation effects at the microscopic level.

    In particular, if the zero-threshold proportional model was correct, the quality factor would be unity for all types of radiation.

    While it's nice that they're at least putting some money in to it, it really isn't a whole lot. Especially when you consider it's 5 separate projects.

    Over five years, so it's a little over 5 million per program per year. A relatively small lab can easily burn half a million a year, so this is funding for maybe ten small labs per program or a couple of larger ones.

    What each program is getting on a yearly basis funds the imperial war machine for just about 5 minutes.

    This is actually a useful number to remember: 600 billion a year comes out to about a million dollars a minute. So when you hear $130 million you should think, "Wow, two hours of military spending!"

    When it says information passed between the two points is information, does it mean it changes energy states?

    No.

    The "thing" that is "teleported" is the quantum state, which is completely different to "teleporting" matter or energy. The state of the "receiver" has exactly the same particle quantum numbers (numbers of photons, electrons, etc) immeiately after the "teleportation" as it does immediately before. As such, "teleporting" a quantum state is completely different from "teleporting" a particle, although for some reason ignorant people keep on claiming otherwise.

    The reason why I have used scare quotes around "thing" and "teleport" in the above is that it is misleading and wrong to use unadorned ordinary language when trying to speak about quantum reality, which is not bound by the same rules of non-contradiction and causality that the world of experience are bound by. A quantum state is not a "thing" in the usual sense at all, which is why it can be "teleported" when the nominally classical particles that carry the state cannot.

    This is /. so I'll try a car analogy, although classical analogies are always tricky with these things. Suppose you have a red car, and a "car colour teleportation device", and I have a blue car, and you trigger your device, which "teleports" the colour of your car to mine (possibliy destroying your car, or its colour, in the process.) So now, whereas before I had a car, I now have a car that is the same colour as yours (was). Then suppose a really ignorant person came along and said, "Wow, a device for teleporting cars! Let me write an article for PopSci on that!" You'd have pretty much the situation we have.

  8. Re:Physics on Instant Quantum Communication Is Near · · Score: 1

    As odd as it sounds, there's not actually any difference between teleporting "only" the quantum state of the photons and teleporting the photons themselves -- provide the state you're teleporting is the entire state of the photon.

    This is an oft-repeated falsehood, promulagated by the vast hordes of ignorant people who swarm around quantum weirdness like moths on a flame.

    If you could "teleport" a photon the photon number at the reciever changes. This is a profound ontological, existential difference from the case where the photon state is "teleported." As it is possible to "teleport" the state of massive particles, perhaps thinking about it in those terms will clear up the mistake for you: if I could "teleport" an electron to the Moon, the electron quantum number, charge, mass and spin of the Moon would be completely different from the case when I "teleport" the state of an electron. Since the two cases are trivially physically distinguishable it is simply false to claim they are the same.

    I really don't know why so many people keep repeating this falsehood.

    But a very simple explanation is that the device always shoots 1 up, 1 down. Sure you don't know if it's up or down until you measure it, but that doesn't make it spooky at all.

    The experimental violation of Bell's Inequalities is inconsistent with this "very simple explanation". That is the whole point of such experiments: they prove that the system is in a (locally) indeterminate state.

    As for "mate competition" - way off there. Wars are no longer fought in order to "git the'r women an' food".

    That whooshing sound you hear is my point passing far over your head. The fact that for some reason you have mentioned "food" in the context of mate competition proves it. War has nothing to do with food, and never has. It's just that really stupid people confabulate impausible bullshit like that to make war sound sensible, when it isn't, ever.

    The "rational" motivation for Germany's attacks on its neighbours that started WWII was the need for land and peasantry to feed the German people. This was the NAZI dream: German imperial rule over Eastern Europe to produce food for Greater Germany.

    Now suppose for a moment that there really was a looming food shortage in Germany. Here are two possible responses:

    1) take a vast quantity of productive labour and other resources out of the economy and put them into killing people and destroying things so that you can repopulate and rebuild in the unlkely event you "win", and after having repopulated and rebuilt in the areas where you have expended enormous otherwise productive labour and resources to kill and destroy, force the people now living there to grow food for you while you continue to expend otherwise productive labour and resources on failing to control the subject population.

    2) Invest in agricultural research and free trade to improve your own agricultural yields and import any shortfall from your more agriculturally gifted trading partners.

    War has nothing to do with control of resources other than (supposed) mating opportunities. No species anywhere ever fights to the death over anything other than mating opportunities. In some species--including humans and and some varieties of deer and elk--control of resources is directly linked to mating opportunities, but those are the only cases where two individuals of the same species will ever fight to the death.

    There is simply no reason to assume that it is any different amongst humans, given that war is always an economic loss: all parties are 100% certain to end up less well off than they would be had they resolved their differences without war. Mate competition is the only motivation that matters.

    It is also a primary motivator in politics.

    So unsurprisingly, I find quoting the dead German I was deliberately riffing of in my statement, "War is a continuation of mate competition by other means" enitrely unconvincing. Clauswitz knew nothing about evolution or economics, and as such he was incapable of appreciating that war makes absolutely no sense (nor do politics, in most cases, as the insane commentatry on Paul Ryan's statist, anti-libertarian health care proposals demonstrates.)

So you are claiming that the segement of the American economy that is least important to overall wellbeing of workers is the one whose activities have driven economic growth. So either your measure of economic growth is unrelated to the wellbeing of workers, in which case it is a very bad metric to use as an arbiter of public policy, or there's something fishy about your claim that offshoring has been a big important deal for Amerian economic growth.

    Also, compared to some other "adventures", [wikipedia.org] the whole thing would be rather cheap

    The challenge for space travel is to get buy-in from the broader population, and to do that it has to have the same visceral, senseless emotional response that warfare has. War is mate competition carried out by other means, and as such engages our deepest emotional responses.

    While exploration is daring and dangerous, the vast majority of people can't participate in it in an active way. We sent 12 people to the Moon, compared to hundreds of thousands rotated through Iraq.

    So from my point of view the problem with exploring other worlds is that we aren't doing enough of it to engage a large enough segment of the population. If some country were to commit to militarizing the Moon, say, we'd see a vast increase in resources flung at space travel, and at this point I'm not sure that wouldn't be a bad thing. Even done by an organization as stupid and inefficient as any standing army, it would be cheaper and vastly less destructive than even a fairly tiny war.
