What is the difference between quantum mechanics and quantum physics?

Click For Summary
SUMMARY

Quantum physics is an overarching term that encompasses various theories based on quantization, including quantum mechanics, quantum electrodynamics, quantum chromodynamics, and quantum geometroydynamics. Quantum mechanics serves as the foundational theoretical framework within quantum physics, focusing primarily on the behavior of particles at the quantum level. In contrast, quantum physics includes both theoretical and experimental aspects, making it a broader field of study. Understanding these distinctions is crucial for students and enthusiasts in the field of physics.

PREREQUISITES
  • Basic understanding of quantum mechanics principles
  • Familiarity with quantum electrodynamics concepts
  • Knowledge of quantum chromodynamics
  • Introduction to quantum geometroydynamics theories
NEXT STEPS
  • Explore the principles of quantum mechanics in detail
  • Study quantum electrodynamics and its applications
  • Investigate quantum chromodynamics and its significance in particle physics
  • Research quantum geometroydynamics and current theories like string theory
USEFUL FOR

This discussion is beneficial for high school students, aspiring physicists, and anyone interested in the foundational concepts of quantum mechanics and its broader implications in quantum physics.

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.
