BTW; "tomcat" can also be spelled with the very same "capital 'T'". - Brad Guth I have considerable experience: buzz, click, whir. I have spent considerable time with the U.S. Government. I know both sides of the equation. On the side of the Gov't, we are dealing with the greatest threats that the U.S. has ever faced. Evil from overseas. Evil from above. On the side of the Lefts, we are turning into a military state which is not that desirable for ordinary living. Constantly, there are requests for the military here, and the military there. What, then, is the solution? We must strictly abide by our Constitution and it's safeguards. We must stick with 'Freedom', and not degenerate into 'Facisim'. We must keep a very strong and capable military. And, of considerable importance, we must push our scientific and technological capability through the ceiling. Why? Because it will enhance our military in it's time of need, enhance our economic strength in it's time of need, and by enhancing the forementioned it will eliminate the need for extremist facist unconstitutional measures. The Congress needs to begin serious -- MASSIVE -- funding of chemistry, engineering, physics, mathematics, and bilogy. How? By pumping serious money into both public and private U.S. colleges and universities, earmarked for special projects relating to military, transport, and computer/communications technology. Also, the setting of of 'Chairs' at U.S. colleges and universities. Roughly 2 million dollars will set up a Professor -- A Chair -- funding not only him, but his heirs to the Chair in perpetuity. Such a Professor is a freebee to the school where he stays, usually teaching a course from time to time, but devoting nearly all of his working time to various 'areas' within his field set up by the contract that goes with the Chair. The U.S. thinks nothing of building a submarine for 5 billion dollars. Spend that 5 billion dollars on setting up 'Chairs' for professors and you would establish 2,500 Chairs throughout the many colleges and universities of the United States. Stipulations can be made that research emphasize certain areas and also that the Professors, themselves, have certain qualifications for the Chair. It might be required that a physics professor, for example, spend his time researching anti-gravity, or that a professor have a Ph.D. in the given field and an I.Q. of at least 140 as demonstrated on a government given I.Q. test, or have a given track record in that particular area of study. But, however it is done, our science and technology must blossom to overcome our current difficulties. Simply ordering the military around is not enough. They are very capable but have to have science/technology on their side even when dealing with the 'threat from above'. Good truth avoidance, tomcat. At least now we know the solution isn't going to be via "tomcat" that'll believe in anything his born-again pagan and otherwise LLPOF government tells him. - Brad Guth |

But see: http://scienceworld.wolfram.com/phys...pretation.html Bohr himself had great difficulty adequately resolving this convoluted question. The view he proposed as the second basic tenet of the Copenhagen interpretation was that reality is created only by the act of observation. In the absence of measurement, according to this view, physical entities have no intrinsic properties. As Bohr stated this "creation-by-measurement" theory, "the measuring result is produced only by the measurement itself" (Murdoch 1987, p. 134). Murdoch, D. Niels Bohr's Philosophy of Physics. New York: Cambridge University Press, 1987. -- When you get lemons, you make lemonade. When you get hardware, you make software. You're missing the point. Your references do not address the issue of reality needing anything. Your references address the issue of the ability of observers to come to some agreement about reality and what it might do. This is a distinctly different topic than the one I addressed. Reality is. It is without our help. If you can demonstrate otherwise I would be interested in such a demonstration. Such a "demonstration" would be difficult, but not totally impossible. The Copenhagen Interpretation was borne of necessity. The 'Double Slit Experiment' behaved differently when observed then it did when not observed. Observed the photons were particles while, unobserved, they created a wave interference pattern on the film. Yes, I agree, "Reality is" but not "without our help." For you see, that which perceives, which watches, laughs, feels, remembers, questions, and wills is not itself an object. And, yes, it is 'us'. So, "Reality is" but not without . . . 'us'. No watcher and reality would be no more than an empty equation, a tree falling in the forest, unobserved. Whether or not "Reality" exists when we are not present in animal form to watch, feel, and breathe, is open to question. And, what is it that 'Questions'? Why, us, of course! If one of us dies then "Reality" doesn't go away for the others, but if all of 'us' die then is it even meaningful to reference "Reality". By the way, meaning lies within us too, not Out There. For something to exist in the light of day requires 'the light of day', the light of someone's eyes, or 'possible eyes'.

Please try to read for comprehension. The Copenhagen Interpretation was borne of necessity. The same can be said of every scientifically based theory. Ever hear of Occam's Razor? You go on and on and say absolutely NOTHING. The 'Double Slit Experiment' behaved differently when observed then it did when not observed. On this you are wrong. You should really try doing science before forming opinions about science rather than forming your opinions after reading popularizations that appear on the backs of cereal boxes or on the prizes inside. Take a light source and shade a screen with an opaque material. Cut two fine lines parallel to one another a small distance apart in the shade. You will see that a Fraunhofer pattern for two slits will appear on the screen due to the interference of light that will vary in intensity according to this charge; http://upload.wikimedia.org/wikipedi...Fringespos.png Of course what it looks like is a pattern of MANY light and dark bars on the screen produced by TWO slits. If you have just one slit you get only one bar. This was done first by Thomas Young in 1805. And explained as the interference of light waves coming from each of the slits by Fraunhofer. There was no mystery about it for 120 years! People looked at it,didn't look at it. Nothing was mysterious about it all. Not a goddamned thing! Certainly nothing at all like your asinine comments here. Then in the 1920s the photoelectric effect was discovered and people began to wonder about the corpuscular nature of light. Bohr came up with a pretty reasonable explanation of things and a good model for the hydrogen atom by making certain assumptions about the MATH involved, and folks looked at the math and tried to figure out what it meant physically. Then, they started fooling around with Young's double slit experiment. What they did is figured out mathematically that if you dimmed down the light source below a certain level, and replaced the screen with a photographic film, then THEORETICALLY you would have only ONE photon in the apparatus at a time. There's only so much energy in a particle of light of a given color, and if you reduced the power of the lamp below a certain level, and computed the flight time of the light from the lamp to the photographic film that replaced the screen, then THEORETICALLY you'd have only one light particle in the apparatus at a time. The question was, WHAT WOULD HAPPEN THEN? Well, it took weeks to get a decent exposure, power levels are so low, but at the end of the day, you get a double slit pattern of many bars JUST LIKE YOU WOULD HAVE AT HIGHER POWERS. NOW, ON A THEORETICAL LEVEL - this doesn't make sense. Because there's only ONE PHOTON in the apparatus - THEORETICALLY. But what really happened is that we used photographic film and a very dim light source to carry out a double slit measurement - and got the results we always got. But theoretically, it caused problems. Because it didn't jive with our ideas of how photons should work, after the photoelectric effect was discovered in 1920s. People wondered how a photon could act like a wave and interfere with itself in an apparatus. Theoretically there must be an aspect of the photon that fills the apparatus and carries out the Fraunhofer calculation. A pretty damned smart particle! lol. Theoretically speaking of course. We talk about the wavelength of light. A certain shade of green light has a wavelength of 550 nm. About half a micron. Very tiny. But theoretically there must be an aspect of the photon - the aspect that causes interference effects - that fills all of space, or at least as much space as is taken up by a double slit apparatus. But realistically it was the same damned double slit experiment Young did, with a few changes, in 1805. We just got our shorts in a twist about how our ideas about the photo-electric effect could be right, and still explain the double slit results under very dim conditions involving photographic film. Nobody knows what it all means at a very visceral level. Sure, we can do the math and make predictions. But we're just turning the crank, and getting the answers - we're not really understanding what's going on. Anyone who claims to explain it is a ****ing liar or loon. Now, there were other experiments of a similar type done after the 1920s. These experiments CLAIM to have observed WHICH slit the photons went through. This is a misnomer, I'll describe HOW they did that below and you'll see there are other things introduced. Others, who popularized this sort of thing CLAIM (we're now talking about scientists talking about scientists who missated exactly what they did The popularizers say that when the photons were watched they acted like particles. And when the photons were not watched, they acted like waves. This is a good popularization, one of the best, that covers most of the basics http://www.whatthebleep.com/trailer/...it.wm.low.html But something's screwy... - I mean have you ever wondered HOW a scientist could KNOW which slit a photon went through in flight without disturbing it? lol- Well, its a quantum eraser experiment. And its not easy to do, or describe. And if we can't figure out what's going on with the 1805 experiment I guarantee that we sure as hell don't know what's going on with THIS quantum eraser experiment! lol. I've extracted the following from Physics 556 Course given at Stony Brook University in the summer of 2002; The light used in this quantum eraser experiment is a special state of light consisting of two photons that are said to be entangled. These photons are intimately intertwined, with polarizations that are correlated. The entangled photons are produced by a process called spontaneous parametric down conversion. This takes place in a special nonlinear crystal called beta-barium borate (BBO). A photon from an argon ion pump laser (351.1 nm) is converted to two longer wavelength (702.2 nm) photons. The two photons go off in two different directions. In this experiment, we call one direction p and the other s. The photons that go down path p are called p photons and those that go down s are called s photons. The interference pattern from the double slit is created and measured in the following way. The s photons are the ones that create the interference pattern. They travel through the double-slit to detector Ds. The p photons travel directly to detector Dp. If Dp registers a photon, it sends a "click" to the coincidence counter. The counter waits for the p photon's entangled partner to be registered by Ds. Once this second "click" is detected, a count is recorded. The counts are tallied for 400 seconds. Then detector Ds is moved a millimeter and the number of counts in a 400 second interval is recorded for the new detector position. This is repeated until Ds has scanned across a region equivalent to the screen in the 1805 Young Experiment, or the photographic film in the 1920s experiment. When we do this we get a pattern like all other patterns thus far. Nothing unusual here. That's because we haven't 'observed' anything yet. We're just getting warmed up. To make the "which-way" detector, a quarter wave plate (QWP) is put in front of each slit. This device is a special crystal that can change linearly polarized light into circularly polarized light. The two wave plates are set so that given a photon with a particular linear polarization, one wave plate would change it to right circular polarization while the other would change it to left circular polarization. With this configuration, it is possible to figure out which slit the s photon went through, without disturbing the s photon in any way. Because the s and p photons are an entangled pair, if we measure the polarization of p to be x we can be sure that the polarization of s before the quarter wave plates was y. QWP 1, which precedes slit 1, will change a y polarized photon to a right circularly polarized photon while QWP 2 will change it to a left circularly polarized photon. Therefore, by measuring the polarization of the s photon at the detector, we could determine which slit it went through. The same reasoning holds for the case where the p photon is measured to be y. The presence of the two quarter wave plates creates the possibility for an observer to gain which-way information about photon s. When which-way information is available, the interference behavior disappears. It is not necessary to actually measure the polarization of p and figure out what slit s passed through. Once the quarter wave plates are there, the s photons are marked, so to speak. The coincidence counts were tallied at each detector location, as before, and it was found that indeed the interference pattern was gone. In case you might be suspicious of the quarter wave plates, it is worth noting that given a beam of light incident on a double slit, changing the polarization of the light has no effect whatsoever on the interference pattern. The pattern will remain the same for an x polarized beam, a y polarized beam, a left or a right circularly polarized beam. It is peculiar then, that the presence of the quarter wave plates causes the s photons to so drastically change their behavior. One can't help but ask, how do these photons know that we could know which slit they went through? Increasing the strangeness of this scenario, the next step is to bring back the interference without doing anything to the s beam. A polarizer is placed in the p beam, oriented so that it will pass light that is a combination of x and y. It is no longer possible to determine with certainty the polarization of s before the quarter wave plates and therefore we cannot know which slit an s photon has passed through. The s photons are no longer marked. The potential to gain which-way information has been erased. The coincidence measurements were repeated with the polarizer in place. When that is done the data shows that the interference pattern is back. How does photon s know that we put the polarizer there? Photon s and photon p are entangled. Photon p must be able to communicate to s through some means that is unknown to us. It must be telling s whether it should be producing a pattern or not. But this does not seem to be the case. Things get stranger still. The experiment up to this point has been performed by detecting photon p before photon s. The erasure of the which-way information was performed by modifying the path of p and then measuring s. One could regain a bit of reassurance in commonsense by believing that there must be some form of communication taking place between photon p and s so that s knows whether to interfere or not. Perhaps photon p encounters the polarizer and sends s an immediate message telling it that it can again go the interference route. This is not the case, however, as the next and final portion of the experiment shows. The path of beam p is lengthened (the polarizer and detector moved farther away from the BBO crystal), so that photon s can be detected first. The interference fringes are obtained as before. Then the quarter wave plates are added to provide the which-way marker. And the same set of patterns is obtained as before. Next the erasure measurement is performed. Before photon p can encounter the polarizer, s will be detected. Yet it is found that the interference pattern is still restored. It seems photon s knows the "which-way" marker has been erased and that the interference behavior should be present again, without a secret signal from photon p. How this happening? It wouldn't make sense that photon p could know about the polarizer before it got there. It can't "sense" the polarizer's presence far away from it, and send photon s a secret signal to let s know about it. Or can it? And if photon p is sensing things from far away, we shouldn't assume that photon s isn't. Perhaps the funny business of entanglement plays a more important role than we thought. The two photons are entangled. They are connected together in a special way that doesn't break no matter how far apart they are. It seems that these entangled photons also have some sort of entangled connection with the quarter wave plates and the polarizer. Entanglement is not something we encounter in our everyday world. The concept of locality does not hold for the entangled state like it does for everything in our experience. We encounter things that have a particular location, we can say that a particular thing is here and not there. We certainly do not encounter things that are in two places at once. However, this is possible on the quantum level. Two photons that are in an entangled state can be separated across the universe, but they are still connected together. In this experiment, with each measurement that was performed, the way the photons were entangled changed. This caused the very strange results that were observed. We like to think about photon p as being in one place and photon s as being in another apart from p. But this is not really the case.. We have to start thinking in ways that aren't consistent with what we experience in our larger scale world. Entanglement seems to play a very important role on the quantum scale of the world, so we need to think about it in new ways. This quantum erasure experiment is one of many experiments being done that provides a way for us to better understand the strange nature of quantum mechanics. We have encountered strange concepts like entanglement and non-locality. Perhaps this is just the beginning of a journey to a deeper understanding of the universe and new discoveries. Now, the important point of disagreement I have with tomcat and Guthball is that they claim to know what the hell this all means. Problem is they don't even know what the hell they're talking about let alone what it means! lol. But one thing can be said certainly about their sort of self-congratulatory narcissistic hubris is - its a solid block to real understanding and real progress. And it makes me want to slap them silly when I am unfortunate enough to read something they have to say. the universe is stranger than we can imagine - and we do our selves and the universe a disservice when we don't try to grow to accomodate its realities. Reality does not need our support or understanding or defense to be what it is. We benefit to the degree we understand reality and our relation to it. But we don't control it, it controls us, and that's just fine. Because we are what we are, and reality is what it is, without our help - no matter how vulnerable that makes people like tomcat and Guthball feel. Observed the photons were particles while, unobserved, they created a wave interference pattern on the film. Bull****. The pattern doesn't change because you closed your eyes you freakin' asshole. The experiment is more involved than that. Young's results are easily described as waves. The photoelectric effect gave us some ideas about photons and corpsucles of light that didn't square with the wave idea. And when we dimmed the light down to one corpuscle at a time in the apparatus we still got interference. This alone is a theoretical conundrum that no one can figure out. But the point is the Young experiment just did what it always did - despite our shorts getting in a twist because we couldn't see how the corpuscular nature of light jived with it. Its all in our head, not the experiment. Now, when we fire pairs of photons that are entangled in different directions and use a correlation counter to detect them, and a computer to add up events, and then measure each angle at a time across the plane where Young's screen used to sit - we can do funny things with the photons - ONE AT A TIME - to make the pattern go away or come back - IN THE ACCUMULATED DATA. The experiment doesn't care if we're looking at the apparatus or taking a ****. The universe is what the universe is without our help. Its WE who can't come up with a consistent THEORY of how things should work. We don't have any deep understanding of what the hell is going on. That's ALL we can HONESTLY say. All the other mumbo jumbo is just hanwaving by assholes. .. Yes, I agree, "Reality is" but not "without our help." You would be making an unfounded assertion then. Because the experiment I just described doesn't need your help to get the results it gets. The results are an interpretation of a highly technical process. Whether you're looking at it, or not, or thinking about it or not, doesn't change a damn thing. What you think the results mean in light of your IDEAS about locality, phase and entanglement - does have an impact, the experiment does what the experiment does with or without you. For you see, that which perceives, which watches, laughs, feels, remembers, questions, and wills is not itself an object. Hm... The only things that I have ever encountered that watch, laugh, feel, remember, question, and wills, occur surrounding objects we call human bodies. Has your experience been different? Or have you not noticed? And, yes, it is 'us'. So, "Reality is" but not without . . . 'us'. No watcher and reality would be no more than an empty equation, a tree falling in the forest, unobserved. Utter bull**** without an ounce of relation to what I originally asked, so how could it be responsive? Sheez. Look tomcat, its real simple. If reality requires your consent, or our defense, or our observation even, to be a certain way - please demonstrate it. The 1960s versions of the double slit experiment are inconclusive. They raise more questions than they answer. Any claims that they provide an answer is DISHONEST. So, why don't you be honest for a change. The experiment didn't care whether you farted during it or not, or were watching it or not. It only cared if you had the quarter plate in front of the slit - and that only changed the population count in a register when it happened. WHAT THAT MEANS NO BODY KNOWS! It certainly doesn't mean that we need to take these great loads of bull**** you're spouting and swallow it! lol. Whether or not "Reality" exists when we are not present in animal form to watch, feel, and breathe, is open to question. In your mind perhaps. But reality doesn't care about that. That's the point. And people who feel powerless and threatened in their lives, don't like hearing that. So they grasp at any sort of bull**** to make them feel they're in charge. They're not. We are an epiphenomenon a side effect of processes we have no understanding of.- processes that extend back to the beginning of time and forward to the end of time. What we do, what we think, what we believe, doesn't matter to reality. What we do what we think what we believe is a result of the operation of reality which proceeds totally unaffected by us in any way. And, what is it that 'Questions'? Why, us, of course! Whatever. Whether we ask questions or not isn't responsive to my original point which is that reality doesn't need our support to be what reality is. If one of us dies then "Reality" doesn't go away for the others, but if all of 'us' die then is it even meaningful to reference "Reality". Bull****. By the way, meaning lies within us too, What things mean have nothing to do with my original question about reality. You really go on and on and on about things to avoid a very simple point just because it threatens your weak sense of self. not Out There. For something to exist in the light of day requires 'the light of day', the light of someone's eyes, or 'possible eyes'. Bull****. The double slit experiment in any form doesn't care whether you're looking at it or not! Shaparelli used 'canali' to describe what he saw on Mars and Percevel Lowell immediately concluded that 'canals' existed on mars and alien races! Shaparelli's unfortunate use of words fired up the imagination of the amateur astronomer Lowell, and created a whole wave of bull**** that still hasn't died down. The unfortunate use of the term 'observer' in certain of Planck's writings have had a simliar effect here - unleasing a huge wave of bull**** that shows no signs of abating. "I cannot think of any better reason for there being a World than that it was willed to be." -- William James. These are articles of Faith, not of science and have nothing at all to do with my simple observation that what is true is true and what is false is false and while we might benefit knowing what is true and what is false within the context of our understanding of reality, reality itself doesn't change one iota because of our knowledge since it doesn't require our support or defense to BE what it IS.. |
