Louis de Broglie 1923 electron experiment showing waves

Click For Summary

Discussion Overview

The discussion revolves around the behavior of electrons in experiments demonstrating wave-particle duality, particularly focusing on why electrons exhibit wave-like properties even when fired individually. Participants explore concepts related to ether theory, the influence of gravity, and the effects of magnetic fields on electron behavior.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants question why electrons behave like waves when fired one at a time, suggesting the possibility of an underlying medium or ether influencing their behavior.
  • Others argue that the wave-like behavior is a result of wave-particle duality, with the explanation varying depending on the chosen interpretation of quantum mechanics.
  • One participant proposes that gravity could be a more logical explanation for the behavior of electrons than wave-particle duality, which they describe as "pure QM magic."
  • Another participant speculates on the effects of magnetic fields on electron trajectories, questioning whether previous interactions with magnetic fields could influence subsequent electrons.
  • Concerns are raised about the potential for materials in the apparatus to retain magnetic influences, affecting the behavior of electrons fired afterward.
  • There is a suggestion that the proximity of the electron emitter to the electrons themselves could play a role in influencing their paths.

Areas of Agreement / Disagreement

Participants express differing views on the mechanisms behind electron behavior, with no consensus reached on the explanations provided. The discussion remains unresolved regarding the influence of external factors like gravity and magnetism on electron behavior.

Contextual Notes

Participants reference various interpretations of quantum mechanics and the historical context of ether theory, indicating a reliance on differing assumptions and definitions that are not fully explored in the discussion.

I was just wondering why they act like waves if the electrons are only fired one at a time and can't influence one another yet they do, is this why some physicist supported the ether theory, that there must be some medium without mass that allows transmission of light and such or maybe just influences the electrons by keeping tabs in a way?

I assume by 'act like waves' you mean that there distribution is the same as a diffraction pattern. Why they interfere with themselves, is simply down to wave-particle duality, a deeper explantion would be dependent on the QM interpretation that was choosen.

No physicist holds to the ether theory as was, this died out with advent of special relativity before the advent of QM.

Maybe because they are bound by gravity. That's a more logic explanation than particle.wave duality (which is pure QM magic!). Aspect's particles are emitted at the same moment. EPR tests show that groups of particles emitted at 'different' moments can have different spin, but each group emiited at the same moment has the same spin.
 
I wonder if a single electron was fired and the the apparatus was passed over with a magnet like deguassing then would the next fired electron not be so effected but travel more as a particle instead of wave. Like on my computer monitor if a get a magnet close enough it severely distorts the colours and bends the paths of the electrons, even after taking the magnet away the colour distortion remains, although I don't recommend anyone do this because I have a degaussing button any could otherwise harm the monitor, but I wonder if the materials of the housing of the monitor are retaining some of the magnetic influence and so influencing the next electrons in this way, and if so then might a single electrons fired in the apparatus influence the material of the apparatus like the magnet to influence the next electron or could it be in the vacuum itself? If it's in the vacuum then there ought to be something in the vacuum that retains the influence, is this the general idea of the choosen QM interpretation?
Thanks for bringing up the other thread jc.
Another thing is what if it where the proximity of the electron emitter to the electron itself or the space directly in front of the emitter that was being affected as a magnetic affects a monitor that was affecting the flight paths of the subsequent particles, I mean if the charge retainment is extremely close then it wouldn't have to be very strong to affect the flight path.
I'm fairly sure the the remaining slight colour distortion of the plastic and glass and wires of the monitor is a very sensitive indicator of the influences of magnetism on materials long after the magnet is moved away.
