I plan to use some of that advice in writing articles, in particular how to distinguish between the sourcing of statements vs. providing good references. Harald88 21:43, 26 October 2006 (UTC)

This was a good edit. CWC(talk) 09:42, 29 October 2006 (UTC)
Hi Harald, Something's wrong here, if I'm not mistaken. I suspect that there is only half a code, and it's screwing up my attempts to add a references section at the bottom. I have made several attempts, but I can't see anything there. Please take a look at it. -- Fyslee 22:20, 2 November 2006 (UTC)
Hi I saw that you added a comment but next deleted it again. Change of mind, reconsideration, ...?

I've found a contempary anti-relativist, of undisputed relevance, verifiable career in academics, enough notability for longish Wikipedia article: William Lane Craig. But whether the argument that an absolute frame of reference is needed for the existence of God will earn him many points here? Nevertheless I'll write Neo-Lorentzian interpretation [2] once I've got enough stuff together. But I won't spend >100 Euro for his ISBN 0792366689. Perhaps KraMuc can buy it ;-) --Pjacobi 17:49, 6 November 2006 (UTC)
Note that even though the centrifugal force is described as 'fictitious' this does not make it any less real. Many other everyday forces such as the force of gravity are actually fictitious forces (in the case of gravity, caused by the distortion of space/time around any object). In a rotating frame of reference the "fictitious" centrifugal force has very real effects, and because of this many people prefer the term 'pseudo force' to denote this.
Saying that it is fictitous implies that it simply doesn't exist; that it's wholy imaginary. The point is that it isn't fictitious, because it is an effect of momentum, which is real.
Thus its fictitiousness is a misnomer.
OTOH:
pseu‧do /ˈsudoʊ/ Pronunciation Key - Show Spelled Pronunciation[soo-doh] Pronunciation Key - Show IPA Pronunciation –adjective 1. not actually but having the appearance of; pretended; false or spurious; sham. 2. almost, approaching, or trying to be.
Seems to me to be precisely true.
(Actually forces in general are arguably pseudo to start with, energy seems much more fundamental, but that's another issue!)WolfKeeper 02:51, 11 November 2006 (UTC)
Do you know/can you recommend:
Seems to be a KraMuc recommendation, which gives me some reservations. --Pjacobi 14:29, 13 November 2006 (UTC)
Harald, why do you keep removing the Tom Roberts reference that clearly disporoves Allais' (mis)interpretation of the Dayton-Miller experiment? Just because it is not published (yet), it doen't mean that it is not correct. The Tom Roberts paper is a very valuable refutation of all the fringe antirelativists misconceptions about the Dayton-Miller experiment. Moroder 16:57, 25 November 2006 (UTC)
harry, please stop adding the reference to a non-peer reviewed Allais paper. You know very well that this is contrary to wiki policy. In addition to this, you are lifting it from the number 1 crank site, the Anti-Relativity Forum. Moroder 16:02, 26 November 2006 (UTC)
harald, why do you keep inserting the incorrect paper by Uniikrishnan as a reference to the "Twin Paradox" article? Even if it was peer reviewed (in an Indian journal!?), it is clearly incorrect. Uniikrishnan uses his own misunderstandings as "corrections" to the mainstream interpretations. Moroder 16:52, 25 November 2006 (UTC)
Moroder, Please keep your opinions to yourself. It doesn't matter if you ridicule certain countries (as long as you don't do it here!), nor does it matter if you think that scientists who have their own opinions are "unscientific" or 'incorrect". Before getting into trouble I advice you to read the policies, starting with WP:NPOV and WP:NOR. Harald88 17:01, 25 November 2006 (UTC)
"The failure of the accepted views and resolutions can be traced to the fact that the special relativity principle formulated originally for physics in empty space is not valid in the matter-filled universe. Planck’s assertion2 that there is no physical method of measurement of the velocity of motion through space is made void by the various markers available in cosmology, especially the dipole anisotropy of the CMBR."
Oh Harald88! By all means you know, that there are zillions of scientific papers published every year. We are advised to use standard textbooks and review papers if available, and use editorial judgement (with the help of the citataion indexes, despite all voiced doubts about their relevance) whether and which research papers to include. --Pjacobi 23:22, 25 November 2006 (UTC)
Hi Harald,
a recurrent theme in your postings is the claim that "nowadays general relativity is regarded as a theory of gravitation".
There is an assessment that takes precedence. Every physicist with a grasp of relativistic physics will endorse that the special theory of relativity is subsumed in the general theory of relativity. (I like to compare it to the way that Kepler's law of areas is subsumed in Newton's theory of motion. Both Kepler's law of areas and Newton's theory are theories of motion, but Newton's theory is way more comprehensive.)
In newtonian dynamics there are separate theories for motion on one hand and gravitation on the other hand. The special theory of relativity is - like newtonian theory of motion - purely a theory of motion. (In fact, in retrospect we know that it is inherently impossible for special relativity to accomodate gravitation.)
The general theory of relativity is way more comprehensive than any of its predecessors. Unlike Newton's universal law of gravitation, it is not just a theory of gravitation, the content of the general theory of relativity is both the full content of the special theory of relativity (theory of motion) and a theory of gravitation.
To my knowledge, the underlying issue that you seek to address, is that you want to argue that nowadays a claim that the general theory of relativity extends the principle of relativity is no longer regarded as tenable. (Problem: the expression, 'extending the principle of relativity' is highly ambiguous. I have seen the expression 'extend the principle of relativity' in several different contexts, with significant differences in intended meaning.)
One thing I can say for sure: the most naive interpretation of the expression 'extending the principle of relativity' is to suggest that acceleration is just as relative as velocity. (Of course, only a moron would suggest such a thing.) Obviously, the general theory of relativity does not extend the principle of relativity in this naive sense.
My personal opinion is that while the general theory is a much more comprehensive theory than its predecessors, the metaphor 'extension of the principle of relativity' is not a suitable methaphor to describe the achievement of the general theory of relativity. But it is just as awkward to suggest that the general theory of relativity is just a theory of gravitation. What takes precedence is that the full content of the special theory of relativity is subsumed in the general theory of relativity. --Cleonis | Talk 02:35, 5 January 2007 (UTC)
Reset indent.
I'd like to recapitulate the essentials:
I apply the following definition: a theory in which acceleration is "just as relative as velocity" would have to be a theory in which in all situations only the relative acceleration between two objects enters the theory. Such a theory is not an option.
In the case of special relativity, reference to a background structure does not enter calculations that involve only uniform velocity.
The general theory of relativity has in common with newtonian theory that in calculations that involve acceleration, reference to a background structure does enter the calculations. In this sense acceleration is not just as relative as uniform velocity, according to GR.
One of the differences between GR and newtonian is that according to the general theory of relativity, inert mass can affect the background structure (even rotate the background structure locally in the form of frame dragging), whereas the newtonian background reference is conceived as immutable.
When Einstein refers to "relativity of acceleration", he is referring to the ability of inert mass to affect the background structure. --Cleonis | Talk 15:14, 10 January 2007 (UTC)
Unfortunately, it would take a lot of words to address the numerous ambiguities. I suppose I should let the matter rest. I can repeat the Einstein quotes that according to me take precedence, but the very fact that you prefer other Einstein quotes than I do is related to unaddressed ambiguities.
The Einstein quotes that in my opinion take precedence:
"To be sure, the accelerated coordinate systems cannot be called upon as real causes for the field, an opinion that a jocular critic saw fit to attribute to me on one occasion." ("Allerdings können als Realursachen für das Feld nicht die beschleunigten Koordinatentsysteme herangezogen werden, welche Meinung ein humorvoller Kritiek mir einmal zuschreiben zu müssen glaubte.") Source: Einstein 1918, Naturwissenschaften
"It is not that in terms of the theory of relativity the case can be construed in such a way that "possibly it is the surroundings (of the train) after all that underwent the change in velocity". We are not dealing here with two different, mutually exclusive hypotheses about the seat of the motion, [...] ("Man darf im Sinne der Relativitätstheorie den Fall nicht in dem Sinne auffassen, "daß es möglicherweise doch die Umgebung (des Zuges) gewesen sei, welch die Geschwindigkeitsänderung erfahren habe". Es handelt sich nicht um zwei verschiedene, einander ausschliesende Hypothesen uber den Sitz der Bewegung, [...]) Source: Einstein 1918, Naturwissenschaften
These are statements about what are overall viable physics hypotheses. Can a change of coordinate system elicit a field in a physical sense? No, declares Einstein: "Allerdings nicht". In the example offered by Herrn Lenard, is it a viable physics hypothesis to suppose that after all it is the surroundings and not the train that comes to an abrupt halt when the train's brakes are slammed on? No, declares Einstein, no two different, mutually exclusive hypotheses.

Thank you for your kind past editing efforts; the heresy of the Aether is now gently available at [5] [6]. Regards --Utad3 17:16, 7 January 2007 (UTC)
[the below mesage ws written on my user page:]
I am partially reverting your 1950 change in mass in special relativity, because 1950 was indeed the referenced start for disuse (please see the references in the article). It is true that Feynman used it, and Melvin Schwartz, and other Nobel Prize winners, but their use was in attempts to explain things to students, to play it down. Thanks. Edgerck 18:48, 6 May 2007 (UTC)
Harald, I wonder if you could help me,I'm trying to find out if the Einstein quote "There is no resolution of the twin paradox within special relativity.", actually appears in his 1918 paper "Dialogue about objections to the Theory of Relativity". I cannot find a copy of this paper online, and I noticed you mention it a few times earlier on. Does it appear?, I would be grateful for your help. ---Swanzsteve 14:14, 26 August 2007 (UTC)
Harald, thanks for the reply, I didnt know Dingle had quoted from Einsteins 1918 paper, I'll have a look at his book again. Is "Dialogue about objections to the Theory of Relativity" the only paper he wrote in 1918? As to the Einstein quote itself: "There is no resolution of the twin paradox within special relativity.", I have seen it on several websites over the years, but couldnt track it down. Most recently I have seen it on a web page by Unnikrishnan, who seems to be quite notorious:- http://www.spectro.jussieu.fr/GREX/Paris05/Talks/Unni2.pdf.
thanks again - Swanzsteve 18:49, 26 August 2007 (UTC)
I have downloaded a copy of Unnikrishnan's paper, and it doesnt include that quote, although the slide show he produced from it appears to show it as a quote. It seems, as you say, to be more of a summary of Einstein's position, since he uses GR to resolve the paradox completely. I would be grateful for copies of the paper and Chang's article since I cant find anywhere to download them, and I'm working in the dark a bit. Do you need my email address? - cheers - Swanzsteve 21:56, 27 August 2007 (UTC)
can you comment here Wikipedia talk:No original research? Slrubenstein | Talk 18:23, 22 September 2007 (UTC)

Because of your participation in discussions relating to the "PSTS" model in the No original research article, I am notifying you that a request for arbitration has been opened here.

The journals you are citing at tired light are all low-impact with respect to the field of interest (astronomy/cosmology). Therefore they have been removed. They will continue to be removed immediately upon you replacing them. Either use articles published in respectable journals or stop this peculiar advocacy campaign. ScienceApologist (talk) 14:44, 31 March 2008 (UTC)
My comments:
1. It is interesting to see how creative ScienceApologist is in bending the Wikipedia rules as part of his continuous efforts to suppress relevant viewpoints that he dislikes - suddenly references need to be "high impact"?! I happen to watch that particular article because it certainly belongs to my field of interest which is physics - even if he tries to take ownership of it with the claim that it exclusively belongs to astronomy/cosmology.
2. Note his recent removal of everything he strives to censor while marking it as "minor change"[7] (I'd call that a dirty trick)!
3. The tactic of information suppression is just one of many in the arsenal of people who try to destroy what Wikipedia stands for[8]. Harald88 (talk) 14:46, 6 April 2008 (UTC)

Do you have any feedback or comments about my "actual" third opinion at Talk:Tired light#Third opinion? Cheers! Vassyana (talk) 05:03, 18 April 2008 (UTC)
Currently I'm taking a long break!
I'm very demotivated by the continued success of contributors who violate the basic values of Wikipedia. In my humble opinion, cranks are not the geatest danger, as they are simply outnumbered. On the same grounds, I see indoctrination and even propaganda by people who want to push the most popular views and hide or misrepresent less popular views as the greatest danger for Wikipedia and the values that Wikipedia stands for. It appears that such people who come here with such wrong motivations (not necessarily consciously) even outnumber all the rest.

Hallo. Although we are not always the same opinion I esteem your knowledge on the history of relativity. Maybe you have a look at s:Wikisource:WikiProject Relativity#Wikisource translations. May plan is to translate all German and French texts of s:Wikisource:Relativity into English. I've noticed that you (?) also translated some texts into English - including the first Poincaré paper. This and the long Palermo-paper were also (independently) translated by me (see June paper and July paper). Currently, I'm translating some texts by Planck and Laue, for example Laue's 1911 text, where he in fact predicted the outcome of a Sagnac type experiment - two years before Sagnac...) --D.H (talk) 15:20, 8 August 2010 (UTC)
