Quantum physics vs. quantum mechanics

Click For Summary
SUMMARY

Quantum physics serves as an umbrella term encompassing various subfields, including quantum mechanics and quantum field theory. Quantum mechanics specifically focuses on the mathematical framework and principles governing the behavior of particles at the quantum level, while quantum field theory extends these concepts to incorporate fields and particle interactions. The distinction between these terms is significant primarily in academic contexts, where quantum mechanics is tailored for advanced study, whereas quantum physics may be more accessible to beginners.

PREREQUISITES
  • Understanding of basic physics concepts
  • Familiarity with quantum mechanics principles
  • Knowledge of quantum field theory
  • Ability to differentiate between fermions and bosons
NEXT STEPS
  • Research the foundational principles of quantum mechanics
  • Explore the concepts of quantum field theory in detail
  • Study the characteristics and differences between fermions and bosons
  • Investigate the historical development of quantum physics terminology
USEFUL FOR

Students and researchers in physics, educators teaching quantum concepts, and anyone interested in the distinctions between quantum physics, quantum mechanics, and quantum field theory.

I've been thinking about the difference between quantum physics and quantum mechanics. What are the difference?

Is quantum physics just a subfield name, and within that there are quantum mechanics and quantum field theory etc. or are all of these three independent subfields of physics?

Is there a reason why you put THIS much effort into what goes in a "name" such as this?

For me, this type of categorization has no significance and is quite interchangable. It is when a name effects the workings of physics and how it is practiced, then it matters (example: a "fermion" is not interchangable with a "boson" where the characteristics matters).

I apologize for the inconvenience.
 
in the common sense, if one's book use quantum physics
this book is written for beginners.
while quantum mechanics "terminology" is written for graduate oriented students and researchers.
