Q: passage: In South Africa, the Firearms Control Act 60 of 2000 regulates the ownership of firearms by civilians. Ownership of a firearm is conditional on a competency test and several other factors, including background checking of the applicant, inspection of an owner's premises, and licensing of the weapon by the police introduced in July 2004. The process is currently undergoing review, as the police are at present, not able to adequately or within reasonable time, process either competency certification, new licences or renewal of existing licences. Minimum waiting period used to exceed 2 years from date of application. The Central Firearms Registry implemented a turnaround strategy that has significantly improved the processing period of new licences. The maximum time allowed to process a licence application is now 90 days.

Q: passage: An especially unusual version of the observer effect occurs in quantum mechanics, as best demonstrated by the double-slit experiment. Physicists have found that even passive observation of quantum phenomena (by changing the test apparatus and passively 'ruling out' all but one possibility), can actually change the measured result. A particularly famous example is the 1998 Weizmann experiment. The ``observer'' in this experiment -- a sophisticated electronic detector -- wasn't human. And yet, possibly because the word ``observer'' implies a person, such findings have led to a popular belief that a conscious mind can directly affect reality. The need for the ``observer'' to be conscious has been rejected by mainstream science as a misconception rooted in a poor understanding of the quantum wave function ψ and the quantum measurement process.
 question: quantum physics tells us that nothing that is observed is unaffected by the observer?

A:
Yes
