  1. Re:Rats fleeing a sinking ship on Tesla Autopilot Crisis Deepens With Loss of Third Autopilot Boss In 18 Months (arstechnica.com) · · Score: 1

    So, what happens if sellers fail to deliver? Would it be considered financial fraud?

  2. Actual physicist here.

    Most if not all the weird phenomena in quantum mechanics more or less come from the same thing: There is less measurable "information" in the state than the size of the state space. Entanglement isn't any weirder than anything else in quantum mechanics, and is a natural part of it. The measurement problem is the strange thing here. If you measure the spin of an electron, you can only get one of two values, +1/2 or -1/2 (in units of hbar), although the formalism of QM allows the spin to be any point on a sphere, where +1/2 and -1/2 are the poles of the sphere. Now, what was the spin of the electron prior to the measurement? There isn't a clear answer to this. Did the spin "change" to +1/2, when you measured it, or was it +1/2 all along?

    Entanglement merely asks the same question.

    If you previously did not know the state of the electron prior to the measurement, it is natural to assume that the electron was in the measured state all along. And if you repeat this measurement many times, you will find that the measurement is always +1/2 or -1/2. So, if you regard your measurement as giving the state before the measurement, that means your source of electrons is generating electrons in the state +1/2 or -1/2 along some axis. The strangeness is that you can choose the axis with which to measure the spin. Choose a different axis, and you will measure +1/2 or -1/2 on the new axis for all the new electrons. It seems like all the new electrons are now aligned with a different axis. How do the electrons that are generated "know" to be aligned with your measurement device? Therefore, you conclude that electrons must be "changed" by the measurement, even though you can never see the change take place.

    But entanglement shows us that if this measurement effect is a "change", then the change must be non-local (spooky action at a distance). That is, it doesn't seem to occur at any particular place and time, but rather globally, like there is a sort of consistency requirement over the whole history of the universe. The measurement effect is a very special kind of "change" which is different than any kinematic change, and can't transfer information.

  3. I've said it before: Slashdot needs a moderation category: incorrect.
    (Some others have called for a moderation category "wrong", but "incorrect" starts with "in-" and is therefore more correct.)

  4. With entanglement, the entanglement part is not actually science. There isn't any way to disprove that measuring one particle affects the other particle.

    Do you even science, bro? I don't think you even know what entanglement is. Entanglement is a part of standard quantum mechanics. It doesn't say that measuring one particle affects the other particle.

    Well, you can blame capitalism for that. Two people working are more productive than one person. With all our automation, we as a society could easily have a 4 hour work week. But economic efficiency is measured by product produced, and leisure time is just waste.

    I'm not sure from the article how eggs and poultry should be combined, since they come from the same source -- can they be added together? Or does it not work like that for various agriculture reasons -- i.e. spent hens aren't typically used for human food in US.

  11. Do you still drink coffee or eat soy products? Those cause more deforestation than any amount of ranching or livestock raising.

    Bullshit. I won't comment on coffee, but almost all soy grown is used for livestock feed. Human consumption of soy is a drop in the bucket.

    I'm not sure why you are going through the trouble of running permutations of 65536 objects.
    If you want a non-repeating series, it's easy to write an algorithm that will count to 10^241. Even by wastefully representing each digit by a byte, you can easily run the algorithm with just 241 bytes of memory, which any computer can do. The problem is that it would take forever to run. Computers cannot run operations infinitely fast. There is a physical limit, although I am not entirely sure what it is.

    I think the grandparent post is missing a logarithm in the definition of entropy. Entropy isn't proportional to the number of possibilities, but the logarithm of the number of possibilities. It's easy to store numbers greater than 10^241, in just 3 lines of text. On the other hand, it is impossible to store numbers of the magnitude e^(10^241).
