An experiment that claims to doom Bohmian Mechanics

Click For Summary

Discussion Overview

The discussion centers on an experiment involving oil droplets that is claimed to challenge Bohmian Mechanics, a deterministic interpretation of quantum mechanics. Participants explore the implications of the experiment and the reliability of the sources discussing it, as well as the relationship between classical fluid mechanics and quantum theories.

Discussion Character

  • Debate/contested
  • Meta-discussion

Main Points Raised

  • One participant references an article claiming that an experiment dooms Bohmian Mechanics but expresses confusion about the details and implications of the experiment.
  • Another participant argues against the validity of the claims made in the articles, suggesting that previous writings by the same author supported Bohmian Mechanics and that the current claims are inconsistent.
  • A different participant expresses skepticism about the accuracy of popular science magazines, stating that they often misrepresent peer-reviewed research.
  • One participant discusses the relationship between classical fluid mechanics and quantum mechanics, suggesting that fluid mechanics serves as an approximation that averages out quantum effects, potentially undermining the relevance of the experiment to Bohmian Mechanics.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the interpretation of the experiment and the reliability of the articles discussing it. There is no consensus on whether the experiment indeed challenges Bohmian Mechanics or if the claims made in the articles are valid.

Contextual Notes

Participants note limitations in the articles' methodologies and the potential for misinterpretation of experimental results. There is an acknowledgment of the complexity of relating classical mechanics to quantum theories, particularly in the context of averaging effects.

I'd ignore this. She had previous written that the experiments might support Bohmian Mechanics. Now it's the opposite. In fact neither article is correct, as the plausibility of Bohmian Mechanics is not related to the experiments being discussed.

I read in the article in Quanta magazine

I would not trust anything I read in any of these pop science magazines. I have yet to see a single claim made in one of them that was a reasonably accurate version of what the actual peer-reviewed paper in question said.

If there is anything classical then it's anything describable by fluid mechanics. From the point of view of quantum-many-body physics fluid mechanics is an approximation of the Boltzmann equation for situations where the medium is close to local thermal equilibrium. Already the Boltzmann equation smears over the microscopic details in a sufficiently coarse way to average out all quantum effects!
