however, it is now clear that the uncertainty principle is a property of all wave-like systems. it arises in quantum mechanics simply due to the matter wave nature of all quantum objects. thus, "the uncertainty principle actually states a fundamental property of quantum systems, and is not a statement about the observational success of current technology". "measurement" does not mean just a process in which a physicist-observer takes part, but rather any interaction between classical and quantum objects regardless of any observer&lt;/u/l&gt;.
