The very existence of Ehrenfest's Theorem says you are wrong. They don't "assume it" -- they have proven it. The theorem doesn't prove that. Yes, it does. Sadly, I can't do your reading comprehension for you. Note the conspicuous lack of the words "conscious", or even "observer". It's hidden in the words "can be known," "physical observable," "physically measurable," and so on. You are now reading what isn't there at all. Clue: your fantasies are not reality. The only way to distinguish unambiguously between the observer and the observed is by making the observer conscious. Otherwise they are the same thing, and so one cannot exercise upon the other an action of which it is incapable until so acted upon itself by that other. As I stated (and as you predictably ignored, and will of course ignore again), even if all of your new-age claptrap was correct, the "observers" are either subject to the dictate of QM itself (ie, there is no distinction between observer and observation, to use your kooky terminology), or they are not. If they are, then they must be microscopic, and you have the problem of identifying these "microscopic consciousnesses". If they are not, then QM as elucidated in any physics textbook can't say anything about them at all -- thus your demands that it do so are without merit. The word "observable" has a precise technical meaning that you are clearly ignorant of. All the "technical meanings" are contrived to avoid recognizing the above. QM was born in mathematics. Some yoyo newage fruitcake reads about "observables" (had they been called "quantifiables" or even "zitnorts", would the nitwits have noticed QM at all?) and elaborates a huge fantasy. But of course, all of this is, as you say, just a conspiracy. And even if "observable" can be construed to mean "conscious observer observing", the plain fact that there are other, completely equivalent, versions of QM that do not use the standard observable formalism basically says you are full of it the "need" for "conscious observers". Which version of QM is correct? Since they make exactly the same predictions, both are. Once again, this is common knowledge in physics circles. The only people who are having problems are the half-educated nitwits like you. And even if "conscious observers" are a requirement, and that the only possible form of QM required wave-function collapse etc, Ehrenfest says that QM is for microscopic stuff. No, Ehrenfest says QM is easier to see in microscopic stuff, which isn't the same thing (and it was already rather obvious). You need to read the theorem again. Derive it, actually. The notion is qualitatively similar to the laws of equilibrium thermodynamics, in that for small ensembles, the laws are regularly violated, but very rapidly -- as ensemble size N increases -- they "take hold" and do not let go. The likelihood of observing a violation of the second law, for example, is non-zero for even a piece of barely visible dust, but so wickedly, superly, incredibly small as to be effectively zero. (Similarly, common microscopic effects like tunnelling ain't gonna happen to macroscopic objects...) Basically, in addition to being supremely ignorant of QM you don't even know where your ill-considered ideas actually lead. To wit: nowhere. This is classic new-age neo-religious bull****. How much mis-education does it take to believe that physical reality does give a **** about what you think? This is a key question, since the very notion is ultimately the core stupidity of the religious, new-age, "conscious observer" bull**** you are spewing. |

writes: Yes, it does. Because you say so? Actually looking at it does not tell me this, so why should I believe your unsupported assertion? As I said: your inability to read is your problem, not mine. Educate yourself. You are now reading what isn't there at all. Clue: your fantasies are not reality. Is there a difference? Are you really this stupid? As I stated (and as you predictably ignored, and will of course ignore again), even if all of your new-age claptrap was correct ... Nothing I'm saying is particularly "new-age." Apparently you are. ... the "observers" are either subject to the dictate of QM itself (ie, there is no distinction between observer and observation, to use your kooky terminology), or they are not. They are not. As conscious entities, they are independent of the physical universe, and thus they can exist without being observed. Then, as I concluded, you are in no position to make any demands of QM. What, then, is your point? (Right: none.) If they are not, then QM as elucidated in any physics textbook can't say anything about them at all ... Conventional science does not address or acknowledge consciousness, since it is a metaphysical phenomenon and science describes only the physical world (the world that can be observed). Baseless assertion. QM was born in mathematics. That's perhaps the most serious problem with it. You inability to understand is the problem. Fortunately, your problem. Some yoyo newage fruitcake reads about "observables" (had they been called "quantifiables" or even "zitnorts", would the nitwits have noticed QM at all?) and elaborates a huge fantasy. What physicists discovered with quantum mechanics had been known to some people for a very long time. But scientists have to discover things for themselves before they'll acknowledge them. Baseless assertion. But of course, all of this is, as you say, just a conspiracy. There is no conspiracy. Context free comment. In addition to an idiot, you are a liar as well? Since they make exactly the same predictions, both are. Ah? In order for them both to be correct, there must not be any objective reality. The two theories are equivalent: they make the same predictions. Basically, your position is lost and you don't know it. Game, set, match -- and you complain there is no more balls. Checkmate, and yet you try and make a move. Is there a better definition of "stupid"? Once again, this is common knowledge in physics circles. The only people who are having problems are the half-educated nitwits like you. Not really. I have it all pretty clear myself. But many scientists must engage in a sort of doublethink to avoid facing some of the metaphysical questions raised by some domains of modern science. The more they learn, the worse this will get, of course. You appeal to a faulty science of your own construction -- a strawman. I attempt to correct you. Now the goalposts are shifted: science is now not important. Stupid, liar, and intellectually dishonest. You need to read the theorem again. Derive it, actually. The notion is qualitatively similar to the laws of equilibrium thermodynamics, in that for small ensembles, the laws are regularly violated, but very rapidly -- as ensemble size N increases -- they "take hold" and do not let go. No, thermodynamics doesn't work that way. Ignorant ****. The likelihood of observing a violation of the second law, for example, is non-zero for even a piece of barely visible dust, but so wickedly, superly, incredibly small as to be effectively zero. It is non-zero. That's the important point to retain. The chances of winning the lottery are effectively zero. Therefore no one has ever won the lottery. Find the error. You are the error. The probabilities in question are far, far, lower. How long do you think you have to wait for all the molecules in the air in your room will rush simultaneously into one corner. Go ahead, compute it. (Similarly, common microscopic effects like tunnelling ain't gonna happen to macroscopic objects...) They are very improbable. They are not impossible, and saying that they will never occur is very risky. They will never happen in the lifetime of this universe. Get back to us if you find yourself spontaneously breathing vacuum. Until then, yours is ignorant drivel. Basically, in addition to being supremely ignorant of QM you don't even know where your ill-considered ideas actually lead. To wit: nowhere. They lead to many things, but most of them are outside of conventional science, and all too often this also means they are outside the ability or will to comprehend of many scientists and others of like mind. Of course, now that you are proven to be wrong on all counts, you retreat into la-la land. Your inability to comprehend is, once more, your problem, not "many scientists". This is classic new-age neo-religious bull****. It has nothing to do with "new-age" or other "new" ideas. Everything you have said is decades old, found in the usual suspects blather. How much mis-education does it take to believe that physical reality does give a **** about what you think? Physical reality is not conscious, and thus cannot care about what I think. Apparently it didn't take much for you... This is a key question, since the very notion is ultimately the core stupidity of the religious, new-age, "conscious observer" bull**** you are spewing. The key questions are the ones that many scientists avoid the most. You are in no position to complain about "avoiding questions", sirrah. |

Actually, it's proven, not merely asserted. Consciousness _is_ a metaphysical phenomenon. Oops - nothing in physics is proven yet as far as I know. It is all about theories and usefullness of the theories. So - how come metaphysic things are proven? The two theories are equivalent: they make the same predictions. Making the same predictions does not make two theories equivalent. Only one can actually correspond to reality; the other is simply wrong. Oh yes - if two theories makes exactly the same predictions - both are equally valid. One of the theories might be less complex or more beautiful. But that does not change the fact that both are equally valid. Epicycles made accurate predictions, too, but they did not correspond to reality. Epicycles made accurate predictions about a part of the reality. So, they were a valid theory for that part. Unfortunately other parts did not meassure up as good. So - we had to give the old theory up. Good thing - the current view on celestial mechanics is not only more accurate - it is also simpler. /Roland |

Oops - nothing in physics is proven yet as far as I know. Who said anything about physics? The metaphysical reality of consciousness is a fact ... but it's not part of physics, which does not address metaphysical reality (physics stops at physical reality, as the name implies). So - how come metaphysic things are proven? In this specific case, because we all have direct experiential proof of the reality of consciousness ... because we are all conscious. The mere fact of being conscious is proof that consciousness is real, and the fact that it cannot be observed is proof that it is metaphysical (the physical world is defined by observation--anything that cannot be observed, in practice or in theory, does not exist physically). Oh yes - if two theories makes exactly the same predictions - both are equally valid. Both may be equally plausible, but only one can be correct. So it depends on what you mean by "valid." If you mean valid = describing reality, a theory may or may not be valid, no matter how accurately it makes predictions. Epicycles made accurate predictions about a part of the reality. So, they were a valid theory for that part. Unfortunately other parts did not meassure up as good. So - we had to give the old theory up. Good thing - the current view on celestial mechanics is not only more accurate - it is also simpler. And it's also incomplete. -- Transpose hotmail and mxsmanic in my e-mail address to reach me directly. |

Then, as I concluded, you are in no position to make any demands of QM. I'm not demanding anything of QM, I'm explaining it. You can't explain what you clearly do not understand. Baseless assertion. Actually, it's proven, not merely asserted. Consciousness _is_ a metaphysical phenomenon. Baseless assertion. You can't even define the word, let alone prove anything about it. The two theories are equivalent: they make the same predictions. Making the same predictions does not make two theories equivalent. Only one can actually correspond to reality; the other is simply wrong. And you are a clueless dweeb. Models are not reality. Epicycles made accurate predictions, too, but they did not correspond to reality. We reject competing models on predictive power combined with bayesian reasoning, not upon whether the model "corresponds to reality". For the simple reason no one knows what the underlying reality is. Many idiots -- religious nutcases of some form or another -- say otherwise of course. The joke is on them though. You appeal to a faulty science of your own construction ... I do not appeal to science, [...] A funny thing to say for someone who purports to offering "explanations" of QM. The probabilities in question are far, far, lower. It doesn't matter how low they are. What matters is that they are not zero. You are completely clueless. They will never happen in the lifetime of this universe. They are _unlikely_ to happen, which isn't quite the same thing. These events will _NEVER_ happen. Actually, it's thousands of years old. The metaphysical aspects of reality were actually known _first_; conventional science began to describe physical reality much later. "To refute the solipsist or the metaphysical idealist all that you have to do is to take him out and throw a rock at his head: if he ducks, he's a liar." -- Edward Abbey I have the rock.

If "consciousness" can't be observed, as you state, then there can't be any "experiential proof". Because if there was such proof, it would constitute an observation, which you claim is not possible. P.S. I still have the rock. Name a place and time and I'll put you to the ultimate test of your idiot beliefs. |
