RIEMANN-GATE : > Relativists are > then able to use the argument of authority to > discredit these critics. (no pun on relativists or relativity and its validity but...) same is done in the math community. they use the argument of authority. even worse , in fact the media requires it ! let me explain : a professor claims no amateur could possible prove RH or claims to have a proof of it himself. he gets published despite being wrong. many others have claimed a proof of RH , and despite the majority probably being wrong , NOBODY of them is being published or even taken seriously. in fact there almost seems to be a ' second hypothesis ' ; only a handfull prof could possibly prove RH and other people are not worth considering , they couldnt succeed. many people send parts of their proofs to profs , to at least try to convince them without giving the full proof ofcourse ( e.g. fear of theft or dishonesty ) but their work is not even considered. in fact , a prof CAN LEGALLY IGNORE EVERY MAIL SEND TO HIM , THEY DONT HAVE ANY RESPONSABILITY IF THEY DONT READ OR REPLY TO INTRESTING MAILS ! in fact , a magazine CAN LEGALLY IGNORE EVERY MAIL SEND TO THEM , THEY DONT HAVE ANY RESPONSABILITY IF THEY DONT READ OR REPLY OR PUBLISH INTRESTING MAILS ! instead of justifying that educational systems , profs , researchers and media blame eachother or otherwise simply: they use the argument of authority. so some people think ; why would they ? there is no money involved in math is there ? YES THERE IS , AND A LOT. fundings , positions , research grants and Millenium prizes for instance. even some less powerfull professors are deliberately ignored by the more powerfull. ( thus its not just about getting a degree first ) no matter how much good math you post , if you start about a proof of RH you lost your career , unless you belong to ' the elite '. i posted about math mistakes of those who are suppose to correct me but in vain. Im willing to bet ; i pay 500 dollar if im wrong , i get 5 000 000 dollar if im correct or the situation is unclear or it turns out the proof already existed or it turns out my math is correct but based on other math told to be true but turning out to be wrong. Using set theory , set topology , vectors , knot polynomials and statistics is not allowed as (or as part of) a disproof of the validity of my proof of RH. seems an unfair bet but if your all so certain ?!? sorry if i started about math , but since this thread is full of critical views , i thought it fitted in. regards tommy1729

From: Pentcho Valev on 4 Feb 2010 05:02 RELATIVITY-GATE: Joseph Goebbels: "If you repeat a lie often enough, it becomes the truth". Nowadays Einsteinians believe that, as they start moving against waves, the wavelength decreases and the speed of the wave remains constant relative to them (so that they can safely sing "Divine Einstein" and "Yes we all believe in relativity, relativity, relativity"): http://sampit.geol.sc.edu/Doppler.html "Moving observer: A man is standing on the beach, watching the tide. The waves are washing into the shore and over his feet with a constant frequency and wavelength. However, if he begins walking out into the ocean, the waves will begin hitting him more frequently, leading him to perceive that the wavelength of the waves has decreased. Again, this phenomenon is due to the fact that the source and the observer are not the in the same frame of reference. Although the wavelength appears to have decreased to the man, the wavelength would appear constant to a jellyfish floating along with the tide." http://www.pitt.edu/~jdnorton/teaching/HPS_0410/chapters/big_bang/index.html John Norton: "Here's a light wave and an observer. If the observer were to hurry towards the source of the light, the observer would now pass wavecrests more frequently than the resting observer. That would mean that moving observer would find the frequency of the light to have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE BETWEEN CRESTS - TO HAVE DECREASED)." A lie that has become the truth CAN be challenged in Einsteiniana but in the end it should be replaced by another lie (the genuine truth should remain buried forever): http://redshift.vif.com/JournalFiles/V17NO1PDF/V17N1GIF.pdf Doppler Shift Reveals Light Speed Variation Stephan J. G. Gift Department of Electrical and Computer Engineering Faculty of Engineering The University of the West Indies St. Augustine, Trinidad, West Indies Email: Stephan.Gift(a)sta.uwi.edu "Light speed variation relative to a moving observer occurring according to classical velocity composition is demonstrated using Doppler Shift. This directly contradicts the light speed invariance postulate of special relativity and confirms ether drift." Pentcho Valev pvalev(a)yahoo.com
From: Pentcho Valev on 8 Feb 2010 11:22 W. H. Newton-Smith, THE RATIONALITY OF SCIENCE, Routledge, London, 1981, p. 3: "For vewed sub specie eternitatis scientists (even physical scientists) are a fickle lot. The history of science is a tale of multifarious shiftings of allegiance from theory to theory." Scientists that are "a fickle lot" kill science much more efficiently than orthodox gatekeepers in science. Nowadays they appropriate and in the end fatally distort any sound heretical idea: http://www.timesonline.co.uk/tol/comment/article7018438.ece Lord John Krebs, Principal of Jesus College, Oxford: "An Oxford colleague, one of the world's top climate scientists, made the same point last week when he said to me: "It's odd that people talk about 'climate sceptics' as though they are a special category. All of us in the climate science community are climate sceptics." http://www.prospect-magazine.co.uk/article_details.php?id=5538 Paul Davies: "Was Einstein wrong? Einstein's famous equation E=mc2 is the only scientific formula known to just about everyone. The "c" here stands for the speed of light. It is one of the most fundamental of the basic constants of physics. Or is it? In recent years a few maverick scientists have claimed that the speed of light might not be constant at all. Shock, horror! Does this mean the next Great Revolution in Science is just around the corner?" http://www.signonsandiego.com/news/2009/dec/13/quantum-challenge-usd-professor/ "Clean-cut and middle-aged, a tenured professor at a conservative Catholic university, Sheehan is hardly a rebel. Yet for years, he and a few other physicists have been pressing peers to re-examine the Second Law of Thermodynamics, one of the most celebrated and cherished tenets of physics. (...) But Sheehan suggests big things are possible if even the tiniest of violations can be proven, and ultimately exploited in an economically feasible way. For example, it might become possible to convert ambient heat into an infinite energy source, he said." Pentcho Valev pvalev(a)yahoo.com

The essence of COSMOLOGY-GATE: http://www.theage.com.au/national/education/wiggles-on-the-dark-side-20100205-nh2d.html "The wavelength of light from a galaxy that is accelerating away from our Milky Way is "stretched" so the light is seen as "shifted" towards the red part of the spectrum." The above fraud is a relatively new version of a classical fraud designed to camouflage the falsehood of Einstein's 1905 light postulate: in order for the speed of light to appear constant, the wavelength should change in an idiotic way (it is granted that the scientific community invariably sings "Divine Einstein" and "Yes we all believe in relativity, relativity, relativity"): http://sampit.geol.sc.edu/Doppler.html "Moving observer: A man is standing on the beach, watching the tide. The waves are washing into the shore and over his feet with a constant frequency and wavelength.

Two years ago Dr. Hubble admitted that the expanding universe might be an illusion, but implied that this was a cautious and colorless view. Last week it was apparent that he had shifted his position even further away from a literal interpretation of the redshift, that he now regards the expanding universe as more improbable than a non- expanding one." http://www.sciscoop.com/story/2008/10/30/41323/484 "Does the apparently constant speed of light change over the vast stretches of the universe?

If so, wouldn't a stick plunged into the pool appear bent as the light is refracted and won't that affect all our observations about the universe. I asked theoretical physicist Leonard Susskind, author of The Black Hole War, recently reviewed in Science Books to explain this apparent anomaly....."You are entirely right," he told me, "there are all sorts of effects on the propagation of light that astronomers and astrophysicists must account for. The point of course is that they (not me) do take these effects into account and correct for them." "In a way this work is very heroic but unheralded," adds Susskind, "An immense amount of extremely brilliant analysis has gone into the detailed corrections that are needed to eliminate these 'spurious' effects so that people like me can just say 'light travels with the speed of light.' So, there you have it.

(...) Take cosmology and the Big-Bang theory of the origin of the universe. Halton Arp was a respected, senior American observational astronomer. He noticed that some pairs of quasars that are physically close together nevertheless have very different redshifts. How exciting! Evidently some redshifts are not Doppler effects, in other words, not owing to rapid relative motion away from us. That means the universe-expansion calculations have to be revised. It may not have started as a Big Bang! That's just the sort of major potential discovery that scientists are always hoping for, isn't it? Certainly not in this case. Arp was granted no more telescope time to continue his observations. At age 56, Halton Arp emigrated to Germany to continue his work at the Max Planck Institute for Astrophysics. But Arp was not alone in his views. Thirty-four senior astronomers from 10 countries, including such stellar figures as Hermann Bondi, Thomas Gold, Amitabha Ghosh, and Jayant Narlikar, sent a letter to Nature pointing out that Big Bang theory: *relies on a growing number of hypothetical . . . things . . . never observed; *that alternative theories can also explain all the basic phenomena of the cosmos *and yet virtually all financial and experimental resources in cosmology go to Big-Bang studies. Just the sort of discussion that goes on in science all the time, arguing pros and cons of competing ideas. Except that Nature refused to publish the letter. It was posted on the Internet, and by now hundreds of additional signatures have been added... (...) Then there's that most abstract of fundamental sciences, theoretical physics. The problem has long been, How to unify relativity and quantum mechanics? Quantum mechanics regards the world as made up of discrete bits whereas relativity regards the world as governed by continuous, not discrete, fields. Since the mid-1970s, there has been no real progress. Everyone has been working on so-called "string theory," which has delivered no testable conclusions and remains a hope, a speculation, not a real theory. Nevertheless, theoretical physicists who want to look at other approaches can't find jobs, can't get grants, can't get published. (...) You begin to wonder, don't you, how many other cases there could be in science, where a single theory has somehow captured all the resources? And where competent scientists who want to try something different are not only blocked but personally insulted?" Pentcho Valev pvalev(a)yahoo.com |
