Appropriate Concepts in the Formulation of Quantum Mechanics

Click For Summary
SUMMARY

The discussion centers on the inadequacy of classical concepts such as position and momentum when applied to quantum mechanics. Participants argue that these terms, while commonly used, do not accurately represent quantum phenomena and can lead to confusion. They emphasize that position and momentum in quantum mechanics are approximations derived from more fundamental concepts, similar to how spacetime intervals in relativity supersede classical notions of space and time. The conversation also explores the need for a more appropriate conceptual framework in quantum mechanics that parallels the invariant spacetime interval in relativity.

PREREQUISITES
  • Understanding of quantum mechanics fundamentals, including wave-particle duality.
  • Familiarity with Heisenberg's uncertainty principle and its implications.
  • Basic knowledge of special relativity and spacetime intervals.
  • Concept of superposition in quantum systems.
NEXT STEPS
  • Research "Quantum Mechanics and the Concept of Complementarity" to explore analogies with spacetime intervals.
  • Study "Heisenberg's Uncertainty Principle" for deeper insights into the limitations of measuring position and momentum.
  • Investigate "Quantum Field Theory" for advanced concepts beyond classical mechanics.
  • Examine "Wave-Particle Duality" to understand the implications of superposition in quantum systems.
USEFUL FOR

Students of physics, particularly those studying quantum mechanics, as well as educators and researchers seeking to clarify the conceptual foundations of quantum theory.

It should be clear that the atoms/molecules in the ball are in a bound state. If you use a spherical well coinciding with the ball, then you are virtually home free in determining the wave function -- forget atom-atom interactions. A crude model to be sure, but it will capture the basic structure of the interior and provide a physically reasonable wave function.

Sorry, I was probably not clear, I didn't mean to compare the ball's dimension with the wavepacket's spreading; I simply intended to ask how to describe the wavepacket of a macroscopic classical object like that ball; I didn't intentionally use the word "macroscopic" or "classical" just because there exists many macroscopic systems which have a quantistic behaviour and microscopic systems which have a classical one.
