Now, I am lost, I am stuck with the Heisenberg principle..
Seriously, the more I read papers, standard textbooks, or any books on it, I find I am more lost, nearly all seem to contradict all.
*http://www.kevinaylward.co.uk/qm/ballentine_ensemble_interpretation_1970.pdf
In page 365,
This asserts that what we know as the HUP relation (which, in the context, is called dispersion principle) is not even closely related to a single measurement of position and momentum. ( I understand what it means about the standard deviation )
*A book called "Philosophy of Quantum Mechanics" claims that Heisenberg meant, by his principle, the measurement of one observable that ruins the measurement of the other.
*Wikipedia, then, says that HUP shouldn't be confused with observer effect, so it's different from what we said.
*Others say that position and momentum are meaningless terms unless the measurement defines them, so it's the HUP...
Another problem is that I'm being unable to trust the standard textbooks this while, because of the many writings that contradict them.
I hope you get me out of this..
Are Physicists actually not agreeing on this, or is it me who can't get the point?
I am interested in last view, it is the most meaningful for me, if you clear it up, I will appreciate it.
I ask you too to clarify the other ideas that some people think are the HUP, but they really are not, and whether their content is true or not.Best Wishes
