Copenhagen: Restriction on knowledge or restriction on ontology?

Click For Summary
SUMMARY

The forum discussion centers on the Copenhagen interpretation of quantum mechanics (QM), particularly its implications on knowledge and ontology. Participants argue that the interpretation suggests not only limitations on what can be known (e.g., position and momentum) but also asserts that these properties do not exist independently of measurement. The discussion highlights the inconsistency in claiming that nature is local while adhering to the Bell theorem, which implies non-locality if reality exists. Key figures such as Heisenberg, Bohr, and modern interpretations like QBism are referenced, emphasizing the philosophical implications of quantum phenomena and the rejection of classical realism.

PREREQUISITES
  • Understanding of the Copenhagen interpretation of quantum mechanics
  • Familiarity with the Bell theorem and its implications on locality
  • Knowledge of decoherence and its role in quantum measurement
  • Basic concepts of quantum probability and non-Boolean algebra
NEXT STEPS
  • Research the implications of the Bell theorem on local realism
  • Study decoherence and its effects on quantum states and measurements
  • Explore modern interpretations of quantum mechanics, particularly QBism
  • Investigate the philosophical debates surrounding physical realism and ontology in quantum mechanics
USEFUL FOR

Quantum physicists, philosophers of science, and anyone interested in the foundational aspects of quantum mechanics and its interpretations.

It is an illusion however that we could have done otherwise.
Yes, but the illusion is so strong that nobody really thinks that way when one is doing something.

No reality until observed.
I think it would be more accurate to say no values for observables until observation. That is not the same as denying reality.

Perhaps plural values is more accurate. There are values, they just aren't fixed.
