I would like to draw your attention to a thread, running on s.p.r., which is closely related to what has been discussed in the (now defunt) thread on the Measurement Problem:

Thanks, I'll check it out tonight.

Thank you sir. I've been following it since your post. The discussion on decoherence has been excellent.

I would like to know, if I may ask, what is your take on the discussion? Do you see any merit to "knowledge" (or change in) being part of the wave function collapse?

I'm just trying to learn here. And I respect your opinions in this.

Regards
Don
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
