Some discoveries alter our perception so fundamentally that they create a void where certainty once stood. Moments when the fabric of our understanding tears open, revealing something that was always there but impossible to see. Like the discovery of the number zero itself these breakthroughs reveal concepts that were always there, hiding in plain sight.

Key points include:</p> <ul> <li><p>The limitation of standard quantum mechanics as being only about laboratory measurements rather than describing reality</p> </li> <li><p>The EPR-Bell argument: EPR shows that either quantum mechanics is incomplete or non-local; Bell proves it must be non-local</p> </li> <li><p>Why the de Broglie-Bohm theory is not just another interpretation but a "rational completion" of quantum mechanics</p> </li> <li><p>Detailed discussion of how the Bohmian theory explains quantum phenomena:</p> <ul> <li>Particles have definite positions but no intrinsic properties like spin</li> <li>The wave function exists in configuration space and guides particle motion</li> <li>Measurements are physical interactions, not discoveries of pre-existing properties</li> <li>Non-locality arises naturally from the wave function in configuration space</li> </ul> </li> <li><p>Critique of alternative approaches:</p> <ul> <li>Problems with Many Worlds interpretation (can't account for probabilities)</li> <li>Issues with GRW/spontaneous collapse theories (ad hoc parameters)</li> <li>Why "statistical independence" arguments against Bell's theorem fail</li> </ul> </li> <li><p>The importance of having a clear ontology in physical theories</p> </li> <li><p>Why tabletop quantum analogue experiments can't capture non-locality</p> </li> <li><p>Discussion of scientific practice and the dangers of excessive skepticism</p> </li> </ul>

And then you ask yourselves, hey, how can I assign sharp values to those things?"</p> <p>• "If you think of the quantization mapping as a mapping within quantum theory, and not the self adjointly operators represent the classical dynamical variables, then Kochen Specker non contextuality is not a plausible assumption because all the most promising quantization mappings, they don't preserve algebraic relations."</p> <p><br /></p> <p>Links/References:<br />• <a href="https://arxiv.org/abs/2106.13502" target="_blank" rel="ugc noopener noreferrer">Introducing the Q-based interpretation of quantum theory</a> by Simon Friederich</p>
