Discussion Overview

The discussion revolves around a recently published paper and its implications for various interpretations of quantum mechanics, particularly focusing on the de Broglie-Bohm (dBB) theory and the many-worlds interpretation (MWI). Participants explore the potential falsification of these theories and engage in speculative reasoning about the relationship between quantum mechanics and music.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants suggest that the dBB theory has been falsified, referencing a previous discussion about the many-worlds interpretation being validated.
  • There are claims that MWI may also be falsified, with participants asking for elaboration on these points.
  • One participant introduces a humorous interpretation linking quantum mechanics to music, proposing that the equation QM=QM implies a connection between mechanics and music.
  • Another participant questions the implications of certain variables being zero in the context of probability calculations related to quantum interpretations.
  • Several participants express interest in creating a computer program to simulate "quantum music," with differing opinions on whether it would resemble traditional music or sound more like white noise.
  • A post references a project involving the Quantum Hall Effects and its implications for sound, suggesting a paradigm shift in perception related to sound and nanospace.
  • Participants discuss a new paper that appeared on April 2nd, with emphasis on the importance of scrutinizing the footnotes for deeper insights.

Areas of Agreement / Disagreement

Participants express a variety of opinions on the validity of different quantum interpretations, with no consensus reached on the status of dBB or MWI. The discussion remains unresolved regarding the implications of the new paper and the relationship between quantum mechanics and music.

Contextual Notes

Some claims made by participants depend on specific interpretations of quantum mechanics and may involve unresolved mathematical or conceptual steps. The humorous connections drawn between quantum mechanics and music are speculative and not universally accepted.

And I bet that you carefully paced your activity here so that you could make this one your 5000th, right? :smile:
 
Looks like dBB has been falsified!

Of course I did, but don't believe me what I say today! o0)

Not very surprising, given that the same day last year we had a proof that many worlds are right (see the closed thread linked in the first post above).

Still, can you elaborate a bit?

Maybe MWI has also been falsified.

"If a classical auditorium listens to the quantum musical state ##| \psi\rangle## in Eq. 1, then the individual listeners may perceive ##| \psi\rangle## very differently; that is, they will hear only a single one of the different tones with probabilities ##|\alpha_{c}|^{2}##, ##|\alpha_{d}|^{2}##, . . ., and ##|\alpha_{b}|^{2}##, respectively."

You are right, the only interpretation that remains consistent with this crucial insight is the QMI (quantum music interpretation). This implies the equation
QM=QM
(quantum mechanics = quantum music). Dividing by Q, this gives
M=M
(mechanics = music) which proves that Einstein was very close to the truth (because he played violline), while Feynman was not (sounds created by drums cannot really be considered a music).

Remarkably, the same result can also be obtained in a totally different way. From the famous equation
ER=EPR
(see http://en.wikipedia.org/wiki/ER=EPR ) one finds
P=1
which means that the probability P that Einstein and Rosen (ER) are right is P=1. But Einstein and Rosen agreed on everything (note ER on both sides of the ER=EPR equation), so this reduces to the conclusion that probability that Einstein alone was right is equal to one. In other words, Einstein was right. Q.E.D.

But what if Q=0?

Or if E=0 or R=0, then P can have any value?

Maybe that can be excluded by considering ##a|0\rangle=0##?

Am I the only one who wants to hear a quantum music piece? Hmm, I guess I could make a small computer program that simulates it...

That could be interesting. I'd like to see what you come up with if you find the time to do it.
I suspect though that it wouldn't sound the slightest bit like 'music' as defined in any cultural context.
More likely white noise is my guess.

It would be interesting if I took two famous pieces and entangled them :biggrin:

This post is not a joke :wink::

Quote from page said:
The Quantum Hall Effects - impulse responses from nanospace for convolution reverb

After many years of fundamental research in cooperation with the Kamerlingh Onnes Laboratory (Leiden Institute of Physics) the ISM studio proudly presents 'the sound of nanospace'. It's all about levels of magnification and breaking down the wall between analog and digital sound. Quantum hall fx are nothing less than a PARADIGM SHIFT in the perception of time and space.

Hear samples - IR only, no other fx used
EDIT: My note: IR means impulse response(s), which are used in convolution reverbs.

The following paper appeared today (April 2nd), but contains an explicit comment that it was submitted at April 1st. So it deserves a full attention here:
http://lanl.arxiv.org/abs/1504.00108

This is not merely a joke, but also has a deeper message ...

A careful scrutiny of the footnotes is essential for a full appreciation of this paper.

[19] Not really relevant, but we realized that we hadn’t quoted Einstein yet.
