>>11233116You fundamentally understand what "observation" is.
There is something in QM called the uncertainty principle. Just like in classical mechanics, all measurements come with some amount of ambiguity, but in QM, this ambiguity is straight up a part of nature and not because our instruments are imperfect. This principle says that the product of the standard deviations of momentum and position are greater than a constant. That is, .
Whenever you measure an objects momentum, you increase the uncertainty of its position and vice versa. Objects where ?p is small are wavelike and objects where ?x are particle like.
There is nothing magic or mysterious about it.
