I'm sure more examples could be found. GregorB (talk) 06:51, 11 May 2009 (UTC)
replies: text: Also, the publications by him (, ) use "Varićak". Jafeluv (talk) 07:47, 11 May 2009 (UTC)

text: In fact, the article gets it wrong, at least in the Sauer case: PDF at arxiv.org uses "Varićak". (I've changed the spelling in the article to reflect the spelling used by respective sources.) I don't know about the other two. Google Books search finds both spellings. Still, as duly noted by Jafeluv above, all three of his publications that could be found online (dated 1903, 1908 and 1912) use "Varićak", strongly pointing to this spelling as correct.

text: Should be mentioned in the article lead by all means - although Google Books puts it at 97-3 in favor of "Vladimir Varićak", "Vladimir Varičak" spelling is apparently not that rare. GregorB (talk) 20:31, 11 May 2009 (UTC)
replies: text: I have moved it to Vladimir Varićak as requested. Please update the lead of the article, thanks. — Martin (MSGJ · talk) 15:07, 19 May 2009 (UTC)

thread_title:  Requested move 

message: Currently the article claims that Varicak's contribution to kinematics "did not lead to any new physical insight". Arnold Sommerfeld also wrote on the hyperbolicity of the kinematic space, and Scott Walter's article (1999) recounts the link made between relativity and hyperbolic geometry. This meagre interpretation of the fact that these men related the abstract study of pure mathematicians to the new view of space and time puts a damper on science. We should celebrate Varicak's insight and see it as a scientific advance rather than brush his work off as insignificant. Statements like the one quoted evidence a point of view that excludes the supporting role that many scientists have made with their papers that are not frequently cited.Rgdboer (talk) 23:43, 20 July 2009 (UTC)
replies: text: Thank you DH for the "did not lead" edit. Yet I see Scott Walter had a similar comment, amazingly after writing what is now quoted in the article. He considers pressures on Minkowski to avoid too much mathematics. Since relativity is mathematical physics the trend to ever deeper analysis is irresistable. The identification and description of "kinematic space", which Walter traces from Minkowski through Herglotz, Klein, and Sommerfeld to Varicak, is a physical insight itself.Rgdboer (talk) 01:56, 10 September 2009 (UTC)

text: I've translated some papers of Varićak into English and put them on Wikisource (s:Author:Vladimir Varićak). --D.H (talk) 14:52, 22 September 2010 (UTC)

text: As this list was published in 1965, it is certainly not in the public domain in the US and cannot be put on Wikisource (a publication date before 1923 is required). BTW: I only translate German texts. --D.H (talk) 07:51, 23 September 2010 (UTC)
replies: text: On a point of information, does not the 1923 rule apply only to exact reproduction of the original work?  As I understand, a translation is considered a new creation and so, in principle, could be published even if it refers to a recent article. Is that not so? JFB80 (talk) 19:24, 23 October 2010 (UTC)
replies: text: I don't think so, as it is a derivative work. See s:Wikisource:Copyright policy#Translations or recordings of a source work. --D.H (talk) 19:52, 26 October 2010 (UTC)
thread_title:  Physical insight 

message: I dont think Scott Walker's comments should be given such a prominent place because what he says is very much a personal and biased view intending to show that Varićak's work is but a slightly different version of that of Minkowski (supplemented by a little trigonometry). It is not based on an actual reading of Varićak's work and is just not accurate.  Would anyone care to comment? JFB80 (talk) 21:21, 5 August 2011 (UTC)
replies: text: Scott Walter is a contemporary writer that has perspective on both hyperbolic geometry and relativity. His comments are valuable since they show the singular status of Varićak as a mathematical physicist in his time.Rgdboer (talk) 23:14, 5 August 2011 (UTC)
replies: text: But they do not show the singular status of Varićak and do not describe his unique contribution. You remarked above that the article claims that Varićak's contribution to kinematics did not lead to new physical insight and in a similar spirit Scott Walker's comments imply that it was all done by Minkowski - very conjectural because Minkowski made no mention at all of hyperbolic (i.e. Lobachevskian) space. And the comments merely credit Varićak with "recapitulating" a variety of Minkowski's results using hyperbolic functions again implying nothing new. Which results could they be?  Minkowski's results were mainly in electromagnetic theory while Varićak was concerned with optics,  The comments are misleading and could be put into the talk page.  JFB80 (talk) 06:59, 8 August 2011 (UTC)
replies: text: Walter is a well-know historian of science, who commented extensively on Varićak's model. Is there another reputable secondary source, pointing out his "unique contribution" and "singular status"? --D.H (talk) 07:59, 8 August 2011 (UTC)
replies: text: I do not know of another reputable secondary source so that is why it is left to people like myself with an interest and some experience to comment. What makes Varićak's work special is that he was the first to understand and demonstrate that the phenomena and formulae of special relativity follow from the assumption of a hyperbolic instead of Cartesian space. That is remarkable and fundamental and something still not generally known or accepted.. I should add that I find Scott Walter's paper excellent in other respects, especially for the historical references, but that should not make it immune from criticism.JFB80 (talk) 19:41, 8 August 2011 (UTC)
