What is the true nature of reality according to quantum mechanics?

Click For Summary
SUMMARY

The discussion centers on the interpretation of quantum mechanics (QM) and its implications for understanding reality. Participants argue that while quantum physics provides a mathematical framework for predicting atomic and subatomic behaviors, it does not necessarily convey a clear depiction of "reality." The conversation highlights the philosophical divide between scientific realism and the mathematical abstraction of QM, with references to notable figures like Heisenberg and concepts such as the Kochen-Specker theorem. Ultimately, the consensus suggests that QM's mathematical nature complicates its relationship with the concept of reality.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with mathematical modeling in physics
  • Knowledge of philosophical concepts such as realism and anti-realism
  • Awareness of key quantum phenomena like atomic spectra and the uncertainty principle
NEXT STEPS
  • Explore the implications of the Kochen-Specker theorem in quantum mechanics
  • Study the philosophical perspectives on realism in the context of quantum theory
  • Investigate the relationship between quantum mechanics and consciousness theories
  • Learn about Ehrenfest's theorem and its relevance to classical and quantum physics
USEFUL FOR

Physicists, philosophers of science, and students of quantum mechanics seeking to deepen their understanding of the philosophical implications of quantum theory and its mathematical foundations.

It is quite nice to have a mental image that reflects ordinary things we already understand. QM really misses the boat on a LOT of that. Things are just incredibly weird, when compared to ordinary macroscopic things. And some things that attempt to be analogous, such as "spin" really don't quite match.

QM does tell about reality, but does so in non-intuitive ways, that don't fit our expectations that we generalize from macroscopic experiences.

there must be something we could consider as real, even if we do not understand it, and our failure to understand surely cannot be a guiding rule for physics. Further, if we take expectation values, following Ehrenfest's theorem, it is surely as real as classical physics.
Most of the weirdness of quantum mechanics comes from the way the math is interpreted - namely by putting far too much emphasis on pure states and Born's rule. With my
thermal interpretation of quantum physics, which works in the Ehrenfest picture of quantum mechanics that treats quantum expectations as real, most weirdness is gone.
