Tom Potter wrote: As can be seen by the debates on and about General Relativity, and the amount of the taxpayers money that is spent on education, seminars, publications, supporting G.R. experts, etc. and the lack of useful applications for it, General Relativity consumes more time and resources to support, than it returns in terms of productivity. So if it can't be applied, the theory shouldn't be studied? And tell me, how does one spend money to "support" a theory. Most work being done on GR is trying to find a situation in which it does not apply, ie. trying to _disprove_ or improve it. Until that is done sucessfully, scientists will continue to apply it to make sense of our universe and it will continue to be taught. For example, I challenge Bill to post how G.R. would model a mass spring system, model a simple series-parallel resistance circuit, or compute the ionization potentials of a few simple atoms. How's this: general relativity is used in GPS systems to compensate for the small delay in time due to the change of the earth's gravitational field between the ground and the satellite. GPS measurements are so fine that this correction becomes significant. Several posters have claimed that "general relativity is used in GPS systems to compensate for the small delay in time due to the change of the earth's gravitational field between the ground and the satellite. GPS measurements are so fine that this correction becomes significant." but I have challenged all of these posters to provide the data that proves their assertion, and so far no one has provided the data. All they have provided are specifications and solutions to equations, which prove nothing. And even if the GPS clocks are offset by some calculated amount to compensate for effects that other models do not provide, this does not mean that G.R. is a cost effective, viable physics theory. In other words, daily adjustments are made to the GPS clocks, and even if the clocks had large drifts, this are compensated for by the daily adjustments. The bottom line is, if a theory is not cost effective, and a simpler theory can do everything the costly theory can do, why waste time, money and resources on the less viable theory? For example, using a theory that gives results to ten decimal places is of no values, if the system artifacts are in the one percent range. This is like calculating a length to ten places, and using an ax to make the cut. As I indicated, I'd like to see a few real world calculations that prove the viability of G.R. in computing spring-mass systems, simple series-parallel resistance circuits, ionization potentials of a few simple atoms, etc. No doubt there are problems such as stresses in critical system components with complex shapes, where it is desirable and perhaps essential to use tensors to generate useable numbers, but this is not G.R. The question is: Is G.R. a viable, cost-effect tool that benefits society, or an over hyped,. limited application, model? -- Tom Potter http://tompotter.us |

Thanks Bill I suggest that the folks who object to General Relativity do so, not because they believe "that it must be a conspiracy of the establishment" but because it is not a viable theory. Those who object to GR should do so for the simple reason that establishment ****heads have never had a viable theory of gravity. As can be seen by the debates on and about General Relativity, and the amount of the taxpayers money that is spent on education, seminars, publications, supporting G.R. experts, etc. and the lack of useful applications for it, General Relativity consumes more time and resources to support, than it returns in terms of productivity. The amount of taxpayer money that spent on GR is close to zero compared to the amount of taxpayer money spent on Calculus and Newton moron gravity. So your comments have been stricten from the cosmic record. Since for one reason the only people who spend taxpayer money on GR are Astronomers, not Mathematician and Chemist ****heads. Who only spend money on particle-nothing. For example, I challenge Bill to post how G.R. would model a mass spring system, model a simple series-parallel resistance circuit, or compute the ionization potentials of a few simple atoms. The few applications that General Relativity models better than more viable theories, do not require G.R. as the practical limits of all but extremely tightly controlled experiments can be modeled by more viable theories, and even the few cases where G.R. makes for an elegant curve fit, the more viable theories can be adapted to account for variations from the simpler expressions of the theory. String Theory has already been trough out. Due to the initial condition that scientients are more clueless about dimensions than they are about taxes. No doubt, elegant theories should be pursued, in the search for subtle effects that can be profitable applied for the advancement of mankind, but as it is, G.R. is a waste of time and resources, and is essentially, a means by which modern day priests extract money from the general public, and charlatans hide behind to pretend to be privy to useful, esoteric knowledge (As a means of stroking their egos, or impressing people.). But, since the Choice in Gravity is limited to Einstein and Feynmann, we've stuck with Einstein by default, since Feynmann was a MORON. To sum up, rather than read the ego tripping, and insults and the rationalizations of the people who defend G.R. I'd like to see objections to my position be expressed in viable, real world calculations such as a spring mass system, a series-parallel circuit, ionization potentials, etc. That's quite trivial. Since the only people who have ever defended GR are mathematicians. Of which Einstone was one. And he would have even had troubles locating a Circuit Court Judge, nevermind a Judge who's opinion really mattered. |

Tom,
The question is: Is G.R. a viable, cost-effect tool that benefits society, or an over hyped,. limited application, model? Probably not. Would you only learn something new if you could apply it to your job so that you can get a raise? If not, why waste money on a book? Just because the knowledge does not directly benefit society monetarily does not mean it is not worth persuing. Man is a curious animal. In my view, far better is it to satiate this curiosity than to save a few extra bucks that you would spend on things that don't really benefit society anyway. |

And when is trying to understand the world a waste of time and money? Now the real world applications of GR may be limited AS YET but for SR it is the plaything of the work a day engineer - I have been assured by one that without SR the cathode ray tube your probably writing this on would not be able to be designed.

They're certainly there, I come across them now and then, even published in the last few years, but I've never tried to make any kind of comprehensive search. First, you're painting with way too broad a brush... It isn't going against the establishment the gives me problems it is the refusal to: 1. Not acknowledging the establishment is usually fully in accord with experiment and so is a perfectly valid theory I can think of several such as Petr Beckmann, Burniston Brown, Herbert Dingle, Thomas G. Barns, Tom Van Flandern, Harold Puthoff, Halton Arp... etc. that challenge conventional perspective. I don't think that ANY would meet this criteria... 2. The belief that you are somehow brighter and better than all the smart people that created the establishment This is simply a red-herring. At the time of many (such as Galileo, Newton, ...etc.) they WERE! This has been the case throughout history, and only history (after the fact sorts it out). Usually those are due to intuitive insights that all others simply do NOT think about! Many aren't of course, but the argument is simply false in the face of history... 3. The discovery of some point that has escaped the attention of generations of students and physicists since Einstein or whoever published their works and when you point out this is highly unlikely - nonsense such as your not independently thinking or whatever is all they can say. That also happens (or are you claiming it does not?). However, science is never injured by ideas. It is severely injured by closed minded bigotry... Since the scientific method sorts it out ideas and philosophical perspectives are beneficial NOT harmful. 4. Delusions of grandeur where that believe they have found something that puts them in the same class as people like Landau of Feynman when their idea is obviously wrong or similar things have been known for some time This is a complaint of personal ego, like Feynman loved to say, "what do you care what other people think". Again, the bottom line is explanatory power. 5. Failure to elucidate the physical basis for their beliefs when simple considerations indicate that what their proposing is more complicated than generally accepted theories. It is even worse when you point this out and the response indicates they do not even understand the fundamental point your making. I suggest you remember what Einstein said about simplicity. Somtimes simplicity leads to extreme complexity. 6. The attacking of the person that originated the theory as if this somehow undermines the countless other people who have written on it as well. And, for the most part (and certainly not always) the perceived attack is transfered in the mind of the reader. The old addage you don't want to be the bearer of bad news to people with extreme egos (like Saddam)... I could go no but I am sure you get the idea. These probably would not apply to articles published is respectable journals. I suspect the tone of the paper would give them away but not reading a lot of journal articles I would not really know.

It isn't going against the establishment the gives me problems it is the refusal to: 1. Not acknowledging the establishment is usually fully in accord with experiment and so is a perfectly valid theory Maybe scientists around the world think they successfully work with a theory that's obviously and fatally flawed, or they know something that the crank doesn't. If experiment shows fast pions to live longer than slow pions, no amount of pontificating to the contrary will change that. But if you've watched some of these discussions closely, it's completely irrelevant to them whether it's fully in accord with experiment. In fact, some of them have mocked the very idea that accord with experiment even matters! They think they know something about how the universe REALLY works, not just appears to but REALLY does, knowledge revealed to the prophet, as it were, and the prevailing theory ain't it. "Einstein's math makes all the right predictions, but the theory is wrong because that's not how nature really works." The quote is a paraphrase because I don't remember exactly how it went, but I'm not otherwise making it up. 2. The belief that you are somehow brighter and better than all the smart people that created the establishment Relativity disproven with nothing more complicated than high school algebra. Gosh, why didn't anyone see that before? See comment on point one. I could go no but I am sure you get the idea. These probably would not apply to articles published is respectable journals. I suspect the tone of the paper would give them away but not reading a lot of journal articles I would not really know. Every once in a while I see the accusation that mainstream journals wouldn't dare publish anything that doesn't agree with "the party line". I don't think the people making those accusations read a lot of journal articles, either. But moreover, they're just plain wrong. E.g. Van Flandern in Phys Lett A (1998) examines some measurements and concludes that the speed of gravity must be greater than 2e10 c. And something related in 1999 that I haven't looked up yet but was referenced in Carlip's reply. And somewhere I have an otherwise mainstream article about acceleration in special relativity that managed to get in some words about local aether theories. You can't just do a keyword search for something like "aether" and get a comprehensive listing of those sorts of articles (but try it and you'll find some). Or the accusation that nobody in "the establishment" cares about the anomalous Pioneer 10 acceleration. Make even the smallest effort to search the literature or arXives and you'll see it discussed. Or other statements about how physicists and the industry of physics works when it's clear they're making **** up. That's something that bugs me. As near as I can figure they assume Usenet is a representative cross-section of the professional work of physics. -- "When the fool walks through the street, in his lack of understanding he calls everything foolish." -- Ecclesiastes 10:3, New American Bible |

Hi Gregory A great idea, but someone is a way ahead of you in doing this. If you are trying to invent new theories in any area of science then I highly recommend the series of books on scientific anomalies by William R Corliss. He has a general anomalies volume and then a further dozen or more, one on each branch of science. His articles are almost all drawn from peer-reviewed journals and are arranged for easy reference. He does have a web site - http://www.science-frontiers.com/ Ray Tomes |

It isn't going against the establishment the gives me problems it is the refusal to: Bill you have had a lot of replies to this, but why not one more perspective. In general a lot of your comments have validity as it applies to many people who post new theories. However there are subtle little errors of generality and exceptions in almost every case. 1. Not acknowledging the establishment is usually fully in accord with experiment and so is a perfectly valid theory This may be largely true (although I would add "observation" as well as "experiment" to cover astronomy). However there are notable exceptions and some of these are in the areas where people make new suggestions. For example, in astronomy the existence of periodicities in redshifts is pretended to not exist as are physical connections between objects at very different redshifts. 2. The belief that you are somehow brighter and better than all the smart people that created the establishment Not brighter than all the ones that created it, just brighter the reactionaries that try to stop any further progress. :-) 3. The discovery of some point that has escaped the attention of generations of students and physicists since Einstein or whoever published their works and when you point out this is highly unlikely - nonsense such as your not independently thinking or whatever is all they can say. The mistakes in papers concerned with EPR / Bell's inequality / Aspect experiment do actually qualify as generations of mistakes, surprising as it may seem. These mistakes relate to the fact that the vast majority of people (scientists included) cannot do statistics, particularly when it relates to conditional probability and subsamples. This has been proven by several people and published in peer-review jouirnals, but the mistakes continue. 4. Delusions of grandeur where that believe they have found something that puts them in the same class as people like Landau of Feynman when their idea is obviously wrong or similar things have been known for some time Definitely not in the same class as Feynmann. I would never for example make the mistake of saying that light is a particle. ;-) 5. Failure to elucidate the physical basis for their beliefs when simple considerations indicate that what their proposing is more complicated than generally accepted theories. It is even worse when you point this out and the response indicates they do not even understand the fundamental point your making. Good comments. 6. The attacking of the person that originated the theory as if this somehow undermines the countless other people who have written on it as well. Yes, this is a serious problem. One reactionary wrote a thing that he called "The crackpot index" for awarding points to crackpots, so I did an alternative one called "The reactionary index" for the other side of the problem. All in jest, but many a true word ... I could go no but I am sure you get the idea. These probably would not apply to articles published is respectable journals. I suspect the tone of the paper would give them away but not reading a lot of journal articles I would not really know. There are many incomprehensible articles in journals, and many mistakes of all kinds in others. Most are never picked up because most journal articles are never critically studied by anyone. A much smaller number of mistakes are perpetrated for decades by "the establishment". I will list a few of these in my opinion: A. The fundamental calculation error in EPR / Bell's inequality which does not understand the difference between a sample and a sub-sample. There is nothing mysterious happening. B. The resulting FTL communication of quantum events that is rubbish. The intelligent physicists know that FTL information transfer is not achieved by EPR experiments and therefore popularised articles are nonsense. C. The belief that M-M experiment disproved an aether. It really proved that matter is made of the same stuff as light, and a further generation had to pass before DeBroglie said a similar thing. However the garbage M-M explanation had by then stuck. D. The big bang theory has been proven to be quite false. Keeping it as a serious theory is an act of religious faith (they want a creation). E. The "Collapse of the Wave-function" is a nonsense. There is no such thing as a "photon in flight". Quantisation exists only at emmission and absorption events and the E/M field is continuous exactly as Maxwell stated. An absorbed photon may be related causually to an emitted photon but it is not "the same photon" as a single emmission may result in more than one absorption events. That is enough to show that stupid ideas can persist in physics for generations. Also, in the group sci.physics.research you cannot even post some experimental results that have been published in peer-review journals because it contradicts the beliefs of the moderators. That is not science, it is religion. Ray Tomes |
