AI Thread Summary
Nonclassical observations can indeed influence classical outcomes, as demonstrated by experiments showing that quantum measurements lead to macroscopic effects. The correspondence principle suggests that while statistics may average out, specific experimental arrangements can reveal significant impacts of quantum choices. The discussion references "Schroedinger's cat" as an illustration of how quantum measurements affect macroscopic systems. This highlights the interconnectedness of quantum phenomena and classical realities. Ultimately, the relationship between quantum measurements and macroscopic possibilities remains a compelling area of exploration.

Can the choices of quantum measurement ever affect subsequent macroscopic possibilities, or do their statistics always average out overall, a la the correspondence principle?
 
Physics news on Phys.org
It is possible to arrange experiments so that the averaging does not wash out the effects. After all, all the "quantum weirdness" experiments show macroscopic effects (bands on a screen or whatever) from quantum causes.
 
That was the whole point of "Schroedinger's cat" wasn't it- that quantum measurements can affect macro systems?
 
Thanks, folks, I just needed to be reminded.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
