What is the connection between QM and classical mechanics? This has never been obvious to me, but it seems that it would be desirable that we should be able to derive the laws of CM from QM, but I've never really seen that done convincingly. Can you actually show that a very large quantum system will follow the laws of CM, just like you can show that CM is an approximation of relativity at low speeds? Can you give me your opinion on the subject?(adsbygoogle = window.adsbygoogle || []).push({});
