Does Matter Really Move Like a Wave and Hit Like a Particle?

Click For Summary

Discussion Overview

The discussion centers around the conceptual understanding of matter's dual nature as both a wave and a particle, particularly in the context of quantum mechanics. Participants explore the implications of this duality and challenge common interpretations and simplifications of these concepts.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that while matter can be described as moving like a wave, it behaves like a particle upon interaction, drawing parallels to a metaphorical description of movement and impact.
  • Others argue that waves can be measured physically through experiments, suggesting that dismissing their physicality is unjustifiable.
  • One participant emphasizes that what is observed in wave phenomena may ultimately reduce to the individual behavior of particles, questioning the nature of what is being measured.
  • Another participant asserts that if something exhibits all properties of a wave, it should be classified as a wave, using an analogy to a duck to illustrate this point.
  • A later reply critiques the initial premise as a misconception, suggesting that the simplification of quantum mechanics into layman-friendly terms may not accurately reflect the underlying theory.

Areas of Agreement / Disagreement

Participants express differing views on the interpretation of wave-particle duality, with no consensus reached on the validity of the initial premise or the adequacy of common explanations.

Contextual Notes

The discussion highlights the complexity of interpreting wave and particle behavior, with participants noting the potential oversimplification of quantum mechanics in popular explanations. There are unresolved questions regarding the definitions and measurements of waves and particles.

TL;DR
Waves are a perceptual phenomena, not a physical one
This is meant as a challenge to look more closely than we usually do to the concepts of "wave" and "particle". You often hear that matters moves as a wave but hits at a particle, making it sound like a super Mohamed Ali's "move like a butterfly and sting like a bee".
To give a simple example I would say that, as a group, water molecules move like a wave, but each molecule moves like a particle.

We can physically measure waves with physical devices in a variety of physical experiments, so saying that they are not physical is rather unjustifiable.

What is being measured is of course physical. But what is being measured?
We all know that all water molecules do is move up and down, and hardly forward and backward. We certainly see a wave, but if we slowed down our vision a few million times or more, all we would see are individual molecules moving up and down.

A wave. What is measured has all of the properties and behaviors that a wave is supposed to have, so it is a wave.

If an object walks like a duck and quacks like a duck and has all of the other properties and behaviors attributed to ducks then it is a duck.

Yes, we often hear that. It is an attempt to simplify quantum mechanics by describing quantum mechanics in layman-friendly language, not an accurate explanation of how quantum mechanics works and the role of "waves" in the theory.

Because the starting point of this thread is a misconception we are closing the thread.
OP is reminded of the forum rule about acceptable sources - "will often hear" is not the starting point for an informed discussion..
