To start off I'd like to apologize ahead of time for the grammatical errors and lack of eloquence that are sure to follow, it's the middle of the night and my mind is wandering but my cognitive capacity to express my self is pretty low at this time.
With that out of the way, I'd like to ask about something which has been bothering me for quite a time now, I finished my introductory QM course about a month ago and one of the postulates that was mentioned was that upon measurement the state of the system will change/collapse/whatever you'd like to call it to the state corresponding to the measurement, now let's look for example at a harmonic oscillator which is something I've observed in labs ( the classical experiment any how), the thing is that for the whole length of the experiment I had my eyes on the oscillator and classically that's fine, but with QM it seems like it should be collapsing all the time while trying to evolve in time in accordance with the solution for Schrodinger's equation, so can anyone shed light on how am I supposed to understand this situation?
To add to the above, I'm aware of the correspondence principle and have seen that for large energies the probability distribution starts to look like the classical distribution, but again this solution fails to take into consideration that the system is under constant observation.
