- At the end of the day, aren't they the same?
The observer effect results from the interaction of a quantum system with a measurement device.
The HUP is more fundamental: it results from the fact that certain quantum measurements cannot be made simultaneously (or, equivalently: certain quantum observables do not commute, most famously - position and momentum).
The relevant wikipedia article says: "Historically, the uncertainty principle has been confused with a related effect in physics, called the observer effect, which notes that measurements of certain systems cannot be made without affecting the system, that is, without changing something in a system."
So, as far as I understand, the HUP is not observer effect. And that's held by the majority of scientists.
How do we know that they are different?Is there an experimental proof or it's all about math? Does the proof depend on the quantum interpretation which is applied?
Any explications of the topic will be appreciated!
