Talk:Laser schlieren deflectometry

Claim of invention

User:Xjschx has added several times a claim that LSD "was invented by Jan Schäfer in Leibniz Institute for Plasma Science and Technology", along with an external link. It seems obvious to me that a solid reference is needed to support that claim, especially since I fear there may be some conflict of interest at hand here. What references exist to back up this invention statement ? Ariadacapo (talk) 07:19, 14 November 2015 (UTC)[reply]

Here is the reference for the claim: AIE - "Laser Schlieren Deflectometry was invented by J. Schäfer in Leibniz Institute for Plasma Science and Technology in 2011." I am sorry for the confusing editing at the beginning of the article - this is the first one :-) Xjschx (talk) 21:21, 20 November 2015 (UTC)[reply]

The page you point to is just copy-paste of a previous version of this article with just the claim of invention added. It is also a copyright violation. Ariadacapo (talk) 06:40, 21 November 2015 (UTC)[reply]

I can see your point but there is no copyright related with the statement on AIE web page. The text just announces a new key scientific article here. It is a kind of PR or news in science. The text on AIE resulted from a discussion between INP and AIE and no copyright agreement has been signed. 88.102.187.74 (talk) 22:21, 21 November 2015 (UTC)[reply]

Oh! So that’s what the "Copyright © 2010 - 2015 All Rights Reserved" statement in the footer means? Or was it perhaps the other way around: the Wikipedia text and image were plagiarized from the "new key scientific article announcement" web page?

Thank you for your hints. Anyway the claim discussed here has been backed up by refering to AIE - as you required. If you see any further problems with the current version of the article feel free to improve it and help with the appropriate form. 88.102.187.74 (talk) 09:11, 22 November 2015 (UTC)[reply]

To be clear: the claim discussed here has not been backed up. A well-intentioned person has only copy-pasted the Wikipedia article on a website with zero editor input, and added the words they wanted to see written in Wikipedia. Please stop using Wikipedia as a soapbox, and kindly move on. Ariadacapo (talk) 09:37, 22 November 2015 (UTC)[reply]

I am sorry, but your deduction is not true. The announcement of the ‘key scientific article’ was already on 9th November 2015 online (you can check it in google or directly at AIE) and the first version of the Wikipedia article is from 12th November. AIE announcement motivated to share the scientific information and facts on Wikipedia. Therefore, thanks editors of Wikipedia for the help with the first version regarding encyclopedic style, putting references and links... Nevertheless, the link to AIE seems to me to be still a regular web reference as required at the beginning of the discussion. I hope the situation has been made clear as I would like to move on to other topics. Xjschx (talk) 19:07, 22 November 2015 (UTC)[reply]

I think that Ariadacapo is probably mistaken here about the referenced page being copied from Wikipedia. It's not clear to me, though, that the referenced web page is a reliable source for the claim of invention. Was the paragraph written by Dr. Schäfer and colleagues and submitted to AIE? How much editorial control does AIE exert over these "Significance Statements"? I don't really doubt the claim, but it would be better if we had an independent source for the information.--Srleffler (talk) 21:02, 22 November 2015 (UTC)[reply]

Either the AIE page has been copied from Wikipedia or the other way around: Compare one with the other:

"Interestingly, the idea of Laser Schlieren Deflectometry represents a direct mathematical and physical analogy to the famous scattering experiment of Ernest Rutherford from 1911. However, instead of alpha particles scattered by gold atoms, here an optical ray is deflected by hot spots with unknown temperature. The deflection of the ray by a cylindrically symmetric temperature profile is evaluated. A fundamental relation has been derived describing the dependence of the maximum deflection of the ray on the local maximum of the neutral gas temperature. Applying Laser Schlieren Deflectometry to a non-thermal atmospheric pressure plasma jet as a prime example for a steep gas temperature gradient allows unmatched spatio-temporally high-resolved analysis of energy balance, heat transfer processes and temperature in the small gas volume of atmospheric plasmas. Thus, the method makes a strong impact on the characterization of plasma sources which have drawn increasing attention in the last years and which represent a new approach for a large variety of technological applications such as surface treatment, coatings, nanomaterial and nanostructure fabrication, and plasma medicine."

The image, which User:Xjschx uploaded and also presented as his own work on Wikimedia Commons, is also identical. Ariadacapo (talk) 07:18, 23 November 2015 (UTC)[reply]

Yes, clearly the Wikipedia article was based on the AIE page, and is too close a copy. The author should have paraphrased better.--Srleffler (talk) 06:43, 24 November 2015 (UTC)[reply]
