    Not true. If they advertise more, they sell more.

    But the competition advertises as well, and thus in the vast majority of cases the only true effect is that you have increased cost on all products. It's a typical case of prisoner's dilemma: The single company is always better off advertising than not advertising, but on a whole, everyone advertising is worse than everyone not advertising.

    Yes, but that's independent of how you receive your TV. If you watch cable TV, you pay the cable in addition to the GEZ fee, the cable fee doesn't include it.

    At this point, the consumer sees cable or satellite TV service as something you pay for

    In Germany, you don't pay for satellite (you do for cable, though).

  6. The travellers update it themselves? on British Airways Set To Bring Luggage Tags Into the 21st Century · · Score: 1

    The travellers update it themselves? Over the phone (i.e. remotely)? I can't imagine that works well.

    Yes, 99% will probably do it properly. But the remaining 1% will cause no end of trouble. Not to mention when someone hacks it and sends other people's bags around the world for the lulz.

    Why not having it programmed at the check-in? I see exactly zero advantage of doing it per phone. You still need to physically put the bag on the counter. So just have a system that programs the tag there.

  11. Re:Fixed the summary on Proof Mooted For Heisenberg's Uncertainty Principle · · Score: 1

    Not all measurement results can be well-defined deterministic properties of the system. If all of them are determined, they cannot be just system properties, but must depend on the way they are measured (i.e. they are contextual), and if all of them are pure system properties (i.e. non-contextual), they cannot be determined.

    I'm not sure whether the problem also occurs with position and momentum, but I'd not be surprised if it does.

    See Wikipedia for details.

  12. Re:It Still Doesn't Mean Much... on D-Wave Large-Scale Quantum Chip Validated, Says USC Team · · Score: 1

    Because a quantum computer has access to operations that a classical computer does not have access to. A quantum computer can evaluate a function on all classical inputs at once; the problem is that you cannot read out the complete result (you can do so by repeating the calculation exponentially often, but then, you lose the advantage over classical computers). Therefore quantum algorithms are about bringing the interesting features into a form that can be easily (efficiently) read out.

    Nonlocality doesn't just mean that particles affect each other over large distances (for that, long-range forces are more than enough), it means that they do so instantaneously. And anyway, even if you accept nonlocality, there's still the noncontextuality problem.

  18. Re:Fixed the summary on Proof Mooted For Heisenberg's Uncertainty Principle · · Score: 1

    But Bell's inequality shows that quantum mechanics isn't compatible with local realism. So you'll at least have to give up locality if you want to maintain that assumption. Moreover, you'll probably get problems with noncontextuality (even in the de-Broglie-Bohm interpretation the measured momentum is not one of the particle's intrinsic properties, but the measurement value only arises through interaction with the measurement apparatus).

    I don't get your example, I think you omitted the complex part.

    No, I didn't. ar is the real part of a, ai is the imaginary part. Same for br, bi and cr, ci.

    But sometimes spreading an operation over several lines makes it harder to read. For example, given the lines

    ar = br*cr - bi*ci;
    ai = br*ci + bi*cr;

    I can spot immediately that this is a complex multiplication. Spread the same code over several lines each, doing only one operation per line, and It will take me some time to figure out.

    Learn some quantum mechanics. And no, I don't mean popular science versions of quantum mechanics. I mean the real theory.

    And yes, I am a physicist. I have learned that stuff. And no, the uncertainty relation is not just a limit on measurement. The quantum state itself does not and cannot contain information about exact position and exact momentum at the same time. Indeed, even though you can formally write down states where at least one of them is exactly defined, those states are not physical. Physical states have neither a well-defined position nor a well-defined momentum. Independent of any measurement.

  25. Re:But what if two observers look at the particle? on Proof Mooted For Heisenberg's Uncertainty Principle · · Score: 1

    Ah,. now I get how you got relativity in. Well, if we measure the same particle, we necessarily do it at the same location, and the relativity of "same time" only happens for measurement on different places; more exactly, for spacelike intervals. Operators belonging to spacelike separated points commute, and therefore there's no uncertainty relation between them (well, formally there's the uncertainty relation with >=0, but since on the left there are only nonnegative quantities anyway, that inequality doesn't restrict anything).
