Discussion Overview

The discussion centers on the nature of physical matter and its relationship to energy, particularly from the perspective of quantum mechanics (QM). Participants explore whether matter can be considered a specific form of energy and how quantum particles are conceptualized within this framework.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that energy and mass are interdependent, suggesting that physical matter might be a peculiar type of energy that manifests as physical objects.
  • Others argue that while energy is a property of matter and fields, matter possesses additional properties such as momentum, angular momentum, and charge.
  • A participant questions the closest notion that describes physical matter from the perspective of QM, indicating that matter is described as quantum fields and their excitations.
  • Some participants assert that particles are distinct entities and that energy is merely a property of these entities, drawing an analogy to colors and objects.
  • There is a contention regarding the definition of "things," with some asserting that quantum particles are indeed "things," while others challenge this notion.
  • One participant emphasizes that particles cannot be equated with energy, momentum, or spin, and that the state of matter (solid, liquid, gas) is determined by molecular interactions as described by QM and chemistry.
  • Another participant suggests that the distinction between "things" and "not things" may be semantic rather than substantive in the context of physics.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the relationship between matter and energy, with no consensus reached on whether matter can be classified as a form of energy or how quantum particles should be defined.

Contextual Notes

The discussion reflects varying definitions and interpretations of fundamental concepts in physics, particularly concerning the nature of particles and energy, which may depend on specific theoretical frameworks.

TL;DR
The nature of physical matter
Energy and mass are interdependent and electrons can manifest as particles and fields as do all other particles, but is it generally true that physical(classical) matter is a peculiar type of energy that can(for some reason? What?) manifest as physical objects?

Energy is a property of matter and fields, but matter and fields have other properties besides energy: momentum, angular momentum (both vector quantities) and charge, for example.

What is the closest notion that describes physical matter from the point of view of qm? Matter is far from being solid substance and we experience it via exchange particles. These exchange particles, if real, are energy, right?

Matter is described as quantum fields and their excitations.

No. Again, particles are "things", and energy is a property of those things. You don't say that red and apples are the same thing, and in the same way matter and energy are not the same thing.

Quantum particles aren't really things and this is why I was looking for a close counterpart. It seems there is none.

I guess it depends how you define "things" but I think most of us here would agree (at the B level of this thread) that quantum particles ARE things and energy is not.

Matter is decsribed by the standard model of particle physics, which is underpinned by QFT (Quantum Field Theory). Particle interactions (in particular the electromagnetic interaction) can be calculated by considering the exchange of virtual photons. Particles cannot be energy any more than particles can be momentum or can be spin. Particles have energy, momentum, charge and spin.

Why matter is solid, liquid or gas depends on how molecules bind together and that is described by QM and chemistry.

Given that all matter is composed of quantum particles, then anything isn't really a thing! But, saying some things are things and some things aren't things is just playing with words. It's not physics.
