What is the difference between quantum mechanics and quantum physics?

Click For Summary

Discussion Overview

The discussion revolves around the distinction between quantum mechanics and quantum physics, exploring whether these terms are synonymous and what each encompasses in terms of study and application.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants propose that "quantum physics" is an umbrella term that includes various theories based on quantization, such as quantum mechanics, quantum electrodynamics, and quantum chromodynamics.
  • Others argue that quantum mechanics is a subset of quantum physics, primarily focused on theoretical aspects, while quantum physics encompasses both theoretical and experimental components.
  • A later reply presents a more abstract view, suggesting a philosophical or poetic interpretation of quantum mechanics.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between quantum mechanics and quantum physics, with no consensus reached on their definitions or scope.

Contextual Notes

Some definitions and interpretations may depend on specific contexts or educational backgrounds, leading to potential ambiguities in the terms used.

I'm a grade 10 student and very much interested in physics. Just wondering the difference between quantum mechanics and quantum physics. Are they synonyms? What would you expect to study in quantum physics and quantum mechanics?

Help please..

"Quantum physics" is an umbrella term that refers to any physical theory based on the notion of quantizing some quantity, like energy.

Quantum physics begins with quantum mechanics, but proceeds into quantum electrodynamics (the quantum theory of electromagnetism), quantum chromodynamics (the quantum theory of nuclear forces), and quantum geometroydynamics (quantum theories of gravity, such as string theory, which are incomplete and under tremendous active study).

I think of "quantum mechanics" as being a subset of "quantum physics." Loosely speaking, quantum mechanics is the theoretical stuff, whereas quantum physics also includes the experimental and observational stuff.
