Please don’t tell me we’re still saying some strings are superior to others. I don't know, but . You might think he spends his ample spare time attacking string theory, but under the covers he’s also promoting and protecting the status quo. ... ''I do not know everything; still many things I understand.'' "A few brilliant theorists came up with the entire concept of quantum physics" The entire history of … A U(1) gauge symmetry is no substitute for that. The solution to the wave equation can be interpreted as leading to the (proper) time indexed flow of a “probability” distribution. I thought they were wrong on certain points. . I didn’t link to the physics detective. Then he asked this: “What is the wave function?” Carroll asked if it’s a complete and comprehensive representation of the world, or whether we need additional physical quantities to fully capture reality. And interesting too. (If they did, they would be taking far too much risk.) The quote, exact words, "If you think you understand quantum mechanics, you don't understand quantum mechanics." I think the answer is interesting because it is telling on several counts. As is “The charge of a single electron polarises the vacuum and an infinite number of electron-positron pairs emerge”. Feynman was known as the great explainer, but he couldn’t explain how a magnet works. It was awaiting censorship, which was duly applied, courtesy of Woit. In the theory of relativity, we can't solve the two-body problem. And then again, when I sort of understand… After a hundred years on the job, our quantum mechanics still don’t understand their subject. I also accidentally came accross a Wikipedia list of famous academic frauds and it added much insight as to the money grubbing that permeates modern science. In contrast, I think that the physics detective blog has provided a space where people can raise non-mainstream issues and consider ideas that genuinely push forward the development of new perspectives in physics. Something similar appears in options pricing in finance. As you pointed out with the behaviour of traders, there are few, if any, real systems that behave like a perfectly random system. Anyway, his last words were music to my ears: “After almost a century of pretending that understanding quantum mechanics isn’t a crucial task for physicists, we need to take this challenge seriously”. It is shame he will not be around to see how things unfold. The first problem is where quantum mechanics uses different rules for quantum objects depending on whether they’re being observed or not. Instead we get fairy tales and lies to children. The control problem is to minimize the price to hedge the option. Maybe their paper might be useful for some things, but I don’t think they come to the right conclusions I’m afraid. It isn’t the only comment that didn’t appear on Woit’s blog. Save my name, email, and website in this browser for the next time I comment. Watching Mr. Apophasia to me is kinda like watching an x-rated circus carnival sideshow , where he projects himself as the carnaval barker and then as the ringmaster, but it turns out he is the circus freak who bites off the heads of the chickens. So much so that on page 161 of Max Born’s 1969 book Physics in my generation, you can read how Einstein told Leopold Infeld that “Here in Princeton they consider me an old fool”. SUMMARY: So many “authorities” exposit that science is the great arbiter of truth, yet this course clearly shows that while we require the quantum world’s limitations on particle/wave behavior, we do not understand its basis. Carroll said the second problem was “we don’t agree on what it is that quantum theory actually describes”. Carroll said until physicists answer these questions, they don’t understand quantum mechanics. Then he pointed out that the reality is exactly backward. He’s a Chief Inspector in the Standard Model Thought Police. Even Physicists Don’t Understand Quantum Mechanics Contact Us The Original "Liberal Forum" - Founded 2003 - America's Political Chat Room Powered by Invision Community I agree. It was Wolfgang Pauli who coined the phrase not even wrong. The can be converted into other particles. At this point, no matter how nice the maths is, we have left the non-linear properties of the real world behind. The Copenhagen interpretation is literally that, an interpretation. I completely agree with his point of view, both for physics and in finance. Nevertheless, Randall's message is: you don't need to understand quantum mechanics to judge the statement. NB: Woit has been badmouthing Carroll some more, using many-worlds ad-hominems. GoletaBeach said “Sean Carroll’s op-ed left me unimpressed”. Then you think some more about electron capture, and then you realise the nuclear force is electromagnetic: It all comes tumbling down. . Richard Feynman famously declared, "I think that I can safely say that nobody really understands quantum mechanics." The existence of such a probability distribution seems mysterious, and has lead to a huge literature. I find his lunatic, narcissistic rants and self indulgent discoveries(?) Oliver Consa has written an excellent article that really should make people question why QED has the status it does. Skimming them, almost all attribute it … They’ve been shying away from understanding it for the thick end of a hundred years, and it’s got to stop, because physics is trapped in an impasse and it’s dying. That we do. Will Kinney said “I guess I was one of the few people who was utterly underwhelmed by Sean Carroll’s Op-ed”. It describes the interaction between light and matter, but it doesn’t describe light or matter or the interaction between light and light. That we do Sean. It certainly is. And particles do not move the way that they do because of vacuum fluctuations. A fine comment. It almost gave Albert Einstein a nervious breakdown: He’s a custodian of ignorance, not a beacon of enlightenment.
