Schmetterling Schmetterling is a German cuss word, created recently, as an urban swear. The definition roughly translates to “b*tch-f*ck”. It also has a double meaning, as it also means “butterfly”, but is rarely used with that meaning.
Jean Bricmont: "All our intuitive notion of causality collapses, because this notion is based on the idea that causes precede effects in an absolute sense that does not de-pend on the reference frame. ... What about QFT or relativistic quantum mechanics ? In standard textbooks, the reduction or collapse of the quantum state is never discussed in relativistic terms−→the question raised by EPR and Bell is not even raised." Oops - Bricmont debunks Quantum Field
@Voidisyinyang Voidisyinyang There is no collapse of the wave function. That is merely an old and meaningless phrase that doesn't want to die. I don't know what Bricmont thinks about these things. You are simply citing out of context. So what? So absolutely nothing. Why do standard QFT textbooks not raise issues like EPR and Bell? Because they are non-issues in physics and QFT is physics. It's not quantum mysticism. ;-)
@Schmetter Ling No offense but do you have any kind of research on this issue? If you read Jean Bricmont's book he is completely against quantum mysticism. On the other hand if you read Nobel Physicist Roger Penrose he is relying on noncommutativity as quantum biology, as is Professor Basil J. Hiley who collaborated with David Bohm. I have corresponded with Professor Basil J. Hiley quite a bit and he does consider the paranormal to be possible in terms of noncommutativity. Why is this? Well if you study the Dirac Dance or Dirac Belt it is a macroquantum example of noncommutativity. I learned the Dirac Dance from my quantum mechanics professor Herbert J. Bernstein who also designed the "donut" noncommutative topology for the quantum teleportation system being tested by NASA. Who did you take quantum mechanics from? Who was your professor? Bernstein worked also on testing Bell's Inequality in the context of David Bohm as well. So Bernstein's view is that the quantum physicist is actually creating a new type of spacetime with each nonlocal quantum measurement. Professor Basil J. Hiley calls this "PreSpace" in terms of the noncommutative measurement as quantum algebra. It's not at all mysticism but rather a higher more advanced science that almost all scientists know nothing about. Yes it's true that there doesn't have to be a "collapse of the wavefunction" when using the noncommutative math. The logical problem of quantum field theory still holds true as Jean Bricmont goes into in the final Q & A part of this video. I'll be happy to transcribe it for you - actually there should be a transcription with this video.
you speak of relativity and you speak of relativistic quantum field theory then i challenge you 1:02:07 to find one book because i didn't check all of them of quantum filtering which where even in the index there is a 1:02:14 mention of words like reduction of the wave function collapse of the wave function and so on so all the quantum 1:02:20 states etc so when you learn quantum mechanics in the first course it's an axiom that you have reduction 1:02:26 when you measure blah blah blah and then when you do quantum Field Theory don't mention it anymore what you do 1:02:34 studying the indeed is scattering cross section on the end that's fine 1:02:39 and it's remarkable but where does the where is the control why is that the quantum theory where is the axiom of 1:02:46 collapse and why isn't there an axiom of collapse well that's simple because the collapse is 1:02:51 is again something happening at the distance instantaneously in EPR experiment 1:02:56 and it's very hard to deal with that in a relativistic way in fact i think it's impossible in the usual way 1:03:02 of thinking about relativity and therefore people don't mention it when they do relativistic quantum 1:03:08 filtering but their quantum Feld Theory is not really relativistic because it doesn't even account for the simple EPR experiment 1:03:17 so let's not put the cart in front of the hose 1:03:23 just tie down your control content gravity and then we'll see how to warn about it okay so uh"
This has nothing to do with quantum mysticism. It is an ontological issue though about the foundation of reality. haha. So for example several scientists are testing Roger Penrose's through that gravity IS the collapse of the wave function - Ivette Fuentes' research team is working on this. And maybe you don't realize that Jean Bricmont cowrote the classic, infamous paper with Sokal castigating against social science using "quantum mysticism." haha.
