  1. Re:Collapsing wave functions? on Reimagining of Schrodinger's Cat Breaks Quantum Mechanics -- and Stumps Physicists (nature.com) · · Score: 3, Interesting

    Do you not know how to read? Read the actual link you linked to; there is basically one person who claims this orthodox interpretation is "now widely felt to be unacceptable." Given how wrong Einstein turned out to be about quantum mechanics, it wouldn't be surprising at all if this one Nobel laureate also turned out to be wrong.

    The farthest you can go (and not be laughably wrong) is that there is broad consensus that there is something to be fixed in Copenhagen interpretation—but there is no other interpretation that is more broadly accepted than Copenhagen interpretation.

    The interpretation of QM, called the Copenhagen interpretation, was clearly wrong which is why nobody believes it today.

    If you believe that, you haven't taken a single course in quantum mechanics. Copenhagen interpretation is still taught as the orthodox interpretation of quantum mechanics—maybe everyone has an issue with the whole idea of non-local collapse of wavefunction (or what makes up a "measurement"), but it's more widely believed than any of the other cooky theories, including some that Einstein proposed.

    Indeed. Agreed on the considerations in funding priority. Fundamental science research is basically a speculative venture—you don't want to do none of it (because that means you limit yourself to a box of knowns), but you don't want your next meal coming from it (... which is I guess why the government has to fund a big portion of it).

    Yeah, that's the old chestnut: let's send men to the moon, so that we can invent better pens.

    I am not saying "don't fund BECs" (I have many former colleagues who'd be mad at me if that's what I was saying). I am saying don't just take scientists at their word when they are trying to hype their own work. If you think used-car salesmen are terrible people when they are trying to sell, physicists are even worse people when they are trying to present their tired, old work as "novel".

    While I wouldn't exactly propose a Ginsburg-like time-limit on affirmative action, if you stop using scientists as your exclusive source when you are making funding decisions, you will come to a natural, sensible limit on how long you would fund basic research that overpromises and underdelivers (in that area, BEC isn't actually the worst offender; it's actually string theory, especially given its stranglehold on an entire sub-discipline).

    You don't need to be a specialist to understand that superfluid is not BEC. They are "related" in the sense that they both involve reaching a macroscopic quantum state by approaching the groundstate of a system involving many particles (you can put superconductor in the same category for that; the Internet forum you linked mentioned Cooper pairs).

    But to use that relationship to say that superfluid is BEC is at best oversimplifying (a very dangerous thing to do when you are not a specialist in the field, hence my "bullshitting" comment) and at worst just throwing jargons around (especially your "cooling with superfluid helium" comment).

    They say fear of God is beginning of wisdom—the very first step in becoming a competent physicist is learning when to admit "I don't know" (hopefully well-before somebody smacks you in the head with a metaphorical 2-by-4).

    In any case, my point isn't that BEC doesn't have interesting interactions/properties; it's that BEC doesn't have interesting applications, where by using BEC, you do some things better than you would have without BEC.

    And you are just cherry-picking to, I don't know what you are doing, because you are not saving any face with your continued insistence in ignorary.

    Yes, I've been insulting to you, and that's because you are so willfully ignorant. If you know nothing about low-temperature physics and ultra-cold gases, admit that and say that you don't know, rather than trying to bullshit your way around. I am not going to bother to try to teach to the unteachable.

    Come back when you have learned some humility.

    Are you sure? First invention of maser: 1953 (one of the fruits of the postwar research). Invention of hydrogen maser (part of atomic clock standard—the actual standard, not some pie-in-the-sky dream of a fevered tenure-seeking researcher): 1962. Only 9 years to a discovery that had lasting practical applications both in science and engineering.

    First BEC was produced in 1995. More than 20 years later, still no use for it, either in science or engineering. People are still trying to do stuff with it, but they are not doing it any better with BEC than they can do without BEC.

    I'm not saying all of science research is useless (if that's true, then I'm useless); I'm saying much of scientific "discovery" is useless, and scientists are kinda last people you should listen to when you are trying to judge how worthwhile their work is—they have their own biases that they won't reveal to you, and even if they are perfectly ethical, they're bound to be afflicted with tunnel vision.

    Nope! Look for BEC here, I dare you.

    That's what they claimed BEC could do; no one has done it. The thing is, lifetime of a BEC is so short (last I heard, on the order of a few seconds), that itself puts significant constraints on precision measurements you can do.

    This is what it comes down to—there have been so few truly new discoveries in physics, that many physicists have become hype artists. If they tell you they discovered something new, bet (on even-money odds) that they didn't. If you can find someone who'll take your bet, you'll get rich soon.
