Justification for no properties before measurement

Click For Summary
The discussion centers on the Copenhagen interpretation of quantum mechanics, specifically the assertion that particles lack definite properties until measured. Key points include the Heisenberg Uncertainty Principle and Bell's Theorem, which argue against the existence of hidden variables and suggest that particles cannot possess simultaneous definite values for all properties. While some argue that particles have inherent properties like mass and charge, dynamic properties such as position and momentum require measurement. The Copenhagen interpretation emphasizes the role of measurement as a fundamental concept, positing that the quantum state reflects the observer's knowledge rather than an objective reality. Ultimately, the conversation highlights the philosophical implications of measurement in understanding quantum systems.

This has been good thread, but the OP's question has been answered and its drifting onto other things. Time to close it. Of course if people would like to discuss some of the other issues a new thread can always be started about those issues.

Thanks
Bill
