    you're kidding, right?

    No, I'm not. I read the indicated section of code as follows: If your party files by the indicated deadline and meets all other requirements, the state must include your candidate's name on the ballot. That's what is meant by "entitled", which is a key word in the law as written.

    It doesn't say squat about late filing. By missing the deadline, they missed the state's guarantee of their names appearing on the ballots. But failing to obtain that guarantee does not somehow imply that the state must prevent their names from appearing on the ballot. Lack of a guarantee is not a guarantee of the opposite thing. I'd expect that election officials can and will include the D and R candidates on the ticket, because there is no legal reason why they shouldn't!

    Of course, it's possible that they could exclude them if they wanted to, because of the missed the deadline, but who would want to throw a monkey wrench that huge into the election process?

    Classical physics tells us that if you know the angle of polarization of a photon, then its chance of passing through a polarizer is the square of the cosine of the difference in angles between the photon and the polarizer. If you have a 45 degree photon, it will always pass a 45 degree polarizer, have a 50% chance of passing a 90 degree polarizer, and will never pass a 135 degree polarizer.

    QM tells us that when you have two entangled photons and measure both of their polarizations, the chance the results will correlate is the square of the cosine of the difference in angles between the two polarizers . If you measure them at the same angle, the results always correlate. If you measure them at 45 degrees apart, the measurements correlate 50% of the time. If you measure them 90 degrees apart, the measurements never correlate (the results are always opposite). No matter how you look at it, this means either the results are predetermined at the time the photons are created based on the angles the polarizers will be at the time the measurements are taken, or that one measurement somehow influences the other later so the past isn't immutable.

    Either way you look at it, it means the universe doesn't work the way we expect it to. If you're a glass-half-full person you want to believe in FTL and time travel, and if you're a glass-half-empty person then you think maybe the universe is deterministic.

  6. Re:Still bound by the speed of light on ET Will Phone Home Using Neutrinos, Not Photons · · Score: 2, Interesting

    Once you observe or measure one particle in an entangled pair, you'll instantly know how the distant "partner" particle is going to look, but doing so breaks the link.

    You're oversimplifying it a bit. There really is something spooky going on there. The full explanation is lengthy, but I'm going to give it a try anyway.

    First off, consider the photon from a classical physics perspective. We know photons can be polarized to discreet angles, and we know how to compute the chances of a photon passing through a polarizer as a function of the difference in angles between the photon and the polarizer. Say you send a beam of incoherent light through a polarizer oriented at an arbitrarily selected 12.34 degrees. 50% of that light will pass through and the other 50% will be absorbed or deflected. But that 50% that passes through will now be oriented at 12.34 degrees. 100% of that beam of light will pass through through one or more polarizers oriented at 12.34 degrees, with no absorption.

    If you pass your beam of 12.34-degree light through a polarizer oriented at 57.34 degrees, you'll find that 50% of that light will be absorbed and the other 50% will pass through, and the 50% that passes through will now be oriented at 57.34.

    If you pass your beam of 12.34-degree light through a polarizer oriented at 102.34 degrees, you'll find that all of that light will be absorbed.

    But, if pass some 12.34-degree light through a 57.34-degree polarizer, and then pass what makes it past that first filter through a 102.34-degree polarizer, you find that 25% of the original beam of 12.34-degree light makes it through. In other words, the light can't be twisted 90 degrees in one step, but it can be done in two steps.

    As it happens, the chance of a photon passing through a polarizer is the square of the cosine of the difference in angle between the photon and the polarizer. For easy remembering, it's 100% at the same angle, 75% at 30 degrees, 50% at 45 degrees, 25% at 60 degrees, and 0% at 90 degrees.



    Now, let's go quantum. In the quantum world, "measuring" the polarization angle of an individual photon has different meaning. If the photon is randomly polarized, you have no way to pin its angle down to a particular value. The best you can do is pass the photon through a polarizer. This will either pass the photon through, aligning the photon's angle to match, or deflect the photon. All that you are allowed to say about the previous polarization angle of a photon that passes through the detector is "well, it wasn't 90 degrees apart from my detector, otherwise it wouldn't have passed through.".

    Now, with entanglement, things become really strange, though. Based on a classical physics view, usinglaws of conservation of this and that you could deduce that a pair of photons created from one subatomic event would have zero net momentum and the same random angle of polarization. You would then go on to predict that if you measured both members of each pair with polarizers set at the same angle, there would be no correlation of results, because each photon would be its own entity with its own 50% chance to pass the deflector or be absorbed by it, each not influenced by the other.

    But quantum mechanics predicts (and I'm actually not 100% clear on why or how) that with entangled photons, the rate of correlation of measurement of their polarization angles is the square of the cosine of the difference in angles between the two detectors. And these predictions are known to be true. There's even a name for them: Violations of Bell's Inequality.

    So, the implications should be pretty clear. If both detectors are at the same angle, their results will correlate 100% of the time. So if Detector A registers a "pass" with one member of an entangled photon pair, Detector B either will have already registered the same result or will eventually register the same result. Note that this applies if you change the orientation of

    A superposition of states simply means that that the particle has an unknown value for the property being discussed. If you pick any random electron up off the street, its spin along any axis you choose to measure is in a superposition of states such that it might be up or down with equal probability. You can't measure this condition of being in a superposition of states because it is not a property of the electron. Rather, it is a condition of the information that you know about the electron. To use a bad coin flipping analogy, if you flip a coin and cover it before looking, you can say it is in a superposition of states between heads and tails with equal probability of each, not because there is anything special about the coin but because you simply don't know the definite answer.

    Entanglement does not allow you to control anything at all about a distant particle. When particles are entangled, that means that measurements taken on both members of an entangled pair will correlate more often than our current understanding of the universe says should be possible. The measuring is a passive thing -- it gets information about the state of the particle. The correlations imply that somehow the entangled particles are linked over distance, or that the future of the pair of particles was predetermined at the time the entangled particles were created.

    It cannot be exploited for communication because in order to even detect the strange correlations, you have to compare measurements, which requires getting information about those measurements to a common location. Suppose I'm doing an experiment with entangled photon polarization, and Alice is trying to send a message by modulating the angle of her polarizer. At Bob's detector, he's getting a 50% hit/miss with each photon that comes his way, no matter what angle Alice sets her polarizer to, and his measurement results are completely random.In order for Bob to decode the message, he has to know what Alice's measurements were.
