  1. Re:Of course we can on If We Can't Kill Cancer, Can We Control It? · · Score: 3, Insightful

    We're not ready as a society for elimination of aging. Currently, with money and power generally growing with age, death is the great equalizer. Rich or poor, everybody dies. This is the only thing stopping unfettered hoarding of wealth. Would Bill Gates give away his money if he never aged? I don't know, but it does seem less likely. We'd be stuck in a society where the elders own and control everything, and the young would fight to survive. Murder would replace age-related illness as the leading cause of death.

    For this society to work, the time value of money has to be negative, not positive. Money has to decay with time, not grow. This is the way money should work today, but good luck convincing our overlords.

    Odd integers are true; even integers are false.

    Arrays can be indexed with () or []. This leads to namespace problems with functions which are also called with (). For example:
    x=a(1,2)
    error: undefined variable a.
    If you want to call function a, you have to forward declare it for this reason.
    There's a different syntax for procedures (which don't have a return value) and functions (which do).

    It is required to assign the result of a function to something. You have to write
    dummy = foo(1,2,3)
    as writing
    foo(1,2,3)
    will give an error.

    Most of the time, a single element array is treated the same as a scalar. But not always, and not being very careful will lead to weird errors.
    There are no zero length arrays.
    An array can be length 1; a multidimensional array can be length [1,2,2], but a multidimensional array cannot be length [2,1,1]. If the last dimension has length 1, it simply vanishes to a smaller dimension, unless already 1 dimensional. Example:
    a = make_array(1,2,2)
    ; a has dimensions [1,2,2]
    a = make_array(2,1,1)
    ; a has dimensions [2]
    This means special code must be written to handle any array operations that might end with last dimension 1.

    Array slices are weird.
    b = a[3,*,2]
    means to take a slice of a along the second dimension. I'd expect the answer to be 1 dimensional, since there's only 1 scan in the slice. But the result has dimensions [1,3]
    On the other hand, a[3,2,*] has dimensions [1,1,3], and a[*,3,2] has dimensions [3]. It makes sense in a convoluted way, but it sucks.

  12. Re:Limits of Measurement on More Quantum Strangeness: Particles Separated From Their Properties · · Score: 2

    This isn't a perfect analogy, but think of a kink in the carpet. You can push it around, like a object, but you can't make it disappear without taking out some slack in the carpet. Now if we define this kink as a particle, it IS a particle. Using this definition, the particle doesn't have a precise position, nor a rigid shape. But a quantum particle isn't at all like a classical big object, which still has a precise position although it is extended over space. The difference is that a quantum particle appears to be a point particle whenever you look at it, located randomly on a screen in a region where the screen intersects the quantum particle wavefunction. That is, the wavefunction can be so large that the particle basically should cover the whole screen, but we only see a single dot on the screen somewhere. By 'appears to be a point', I mean that the particle collapses onto the resolution of the screen, no matter how high resolution the screen has, to the limits which we can make screens, and a single particle won't excite two neighboring screen pixels at once. Unfortunately, I don't think there's any way to understand this classically.

    IAAPhysicist. Parent isn't correct. I advise you to not worry too much about what is "real" and accept that physics looks for simple models which match our experiences. You need to think abstractly, and assume less. For example, everyone grows up with some intuition of what an object is, and then project that notion into realms where they don't apply. The letters on this webpage, for example.... These are black objects which move up and down when you scroll the page. Or, is it really the white spaces between the letters which are the real objects, and the black is just void? Actually both are wrong, and the "reality" is that your monitor is doing certain things, depending on how deep you want to look.

    When physicists talk about a particle, they are talking about the smallest step in the amplitude of the fluctuation in some field or combination of fields. A fluctuation doesn't have to be purely one kind of field; for example, a phonon is made out of collective motions of atoms, and polaritons are sort of some mix of photon and phonon. These could be considered particles (but not fundamental particles). This isn't the only way to think about a particle (since it's all just a model anyways), but it is more accurate than billiard balls.

    Heisenburg uncertainty principle exists because you are trying to pinpoint a fluctuation in fields which occupy all space.

    Parent's description of the double slit experiment is fully wrong. Electrons do not interfere with some build up of electrons. Electrons interfere with themselves, because the fluctuation (which is the electron) exists in the full region between the source and screen. The interference pattern is the same no matter how slowly (in terms of electron rate) you fire the electrons, so build up is not a concern. A similar interference pattern exists in photons and neutrons as well, which aren't charged.

Or are you a statist, who thinks that states should enforce contracts that violate rights, by enacting Jim Crow laws. If a contract has to be enforced, then it's not free.
