    As the cat is an active observer inside the box, isn't the whole premise of the thought experiment flawed? On a related topic, in a QM collapsing-the-waveform sense, what does an "observation" mean? Does it mean an observation by an intelligence or just an interaction with another system? If the latter, then wouldn't "interaction" be a better description than "observation"? If the former, then how does the QM system being measured know that the interaction it is experiencing is an observation by an intelligence and not just a random interaction with a passing particle/wave? And finally, how much Scotch does it take to make yourself believe you understand this stuff? Edit: An interesting blog entry on this topic is here[^].

    Well, if the cat is asleep all the time it stays in the box, then it can't be an active observer.

      This discussion is 80 years out of date. Collapse of the wavefunction is an idea from the 1930's.

        "As the cat is an active observer inside the box, isn't the whole premise of the thought experiment flawed?" More importantly than that, whenever I put my cats in boxes, they usually make it known that they are still very much alive without my having to peek inside, not to mention that they are not terribly happy about their predicament either. Cat in a box? Schrodinger obviously never took his cat to the vet :)

          I always thought that the point of the thought experiment was that "you don't know anything until you get off your behind, open the box, and take a look." Without gathering additional information, the cat is both "as good as new" and "as good as dead" as far as the rest of us are concerned - and the cat doesn't get a vote in the matter. Perhaps I missed the point of the lecture way back when... :doh: As far as the use of synaptic efficiency enhancer goes, I think 3 full shots of a reputable single-malt will get you started nicely.

            You're over thinking it. It's a thought experiment and, like an analogy, it only goes so far.

            Even moreso, it was a thought experiment to show "this is ridiculous, that's really what you are planning to use?"

              If there is a TRUE observer this piece of reality needs to be simulated. If the observer is part of the simulation, obviously, it is not needed. If it is not simulated their state remains uncertain... It's a matter of resource saving. So the premise is correct if the cat is not a TRUE observer. Hope this helps ;)

                Your explaination is well put. :) My point exaclty! :thumbsup: Just because it wasn't observed, doesn't mean it didn't happen. Things happen all the time without being observed. Observation proves that stuff does happen and that observed reactions can be reasonably expected to occur again.

                It was broke, so I fixed it.

                  The fact that we make the observation is made , means that the system is not in a quantum state (unknown/variable/anything is possible). and about intelligence , just because my retard friend makes the observation; the outcome doesnt change. (id take a shot at IQ saying that its just bullcrap because QM doesnt vary with IQ)

                    It was only recently when I found out that cats do not, in fact, have nine lives.

                    How do you know he didn't already use up the other eight and you didn't observe it? :-D
