Talk:Meghnad Saha

Untitled

I remember having read the Scientific American essay arguing that Saha's work established the field of Astrophysics. But I don't have the reference. We need to add that reference to the article. DaveBorman 19:01, 18 February 2007 (UTC)

Name

M. N. Saha is Megh Nad Saha or Meghnad N. Saha? Is the name correct on the article? STTW (talk) 21:07, 18 March 2007 (UTC)

Name is not correct. It is plain Meghnad Saha. Its not M. N. Saha, Megh Nad Saha or Meghnad N. Saha.GDibyendu (talk) 14:12, 3 April 2008 (UTC)

Actually, this question came up before, and someone showed that Dr. Saha himself used "Megh Nad" to write his name. In WP, the convention is to follow the spelling used by the subject. --Ragib (talk) 15:07, 3 April 2008 (UTC)

Citizenship

Attempts have been made to either omit Meghnad Saha's citizenship or describe him by a sub-identifier like "Bengali". Meghnad Saha became an Indian citizen on 15th of August, 1947 and remained an Indian citizen till his death. He was not even simply a passive Indian citizen - he was more than that and had his role in struggle for Indian nationalism in the British Raj [Source: http://scitation.aip.org/content/aip/magazine/physicstoday/article/69/8/10.1063/PT.3.3267]. Not acknowledging him as an "Indian" would be much the same as calling Mohandas Karamchand Gandhi as "Gujarati" and not Indian. All neutral sources including the mentioned Physics Today article and Britannica encyclopedia refer to him as "Indian" and according to standards of international reading, that is what should be reflected in the main article as well.

Fair use rationale for Image:Meghnad saha.jpg

Image:Meghnad saha.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.BetacommandBot 22:30, 5 June 2007 (UTC)

Proposed move

It seems that this article uses "Meghnad" throughout, and that is also how most external sources refer to his name. If there are no objections, I propose renaming this article to "Meghnad Saha". Shreevatsa (talk) 02:31, 29 December 2008 (UTC)

No, the article was previously at that spelling. However, someone had shown conclusive evidence that the subject himself used the spelling "Megh Nad" instead of Meghnad. If anything needs change, the article content should be changed to reflect the spelling per the subject. --Ragib (talk) 02:41, 29 December 2008 (UTC)

See the log of the move. --Ragib (talk) 02:43, 29 December 2008 (UTC)

Oh, ok. Then the article should mention that he signed his name as "M. N." and "Megh Nad" -- are there any references (perhaps nothing other than "all his papers", I guess)? In any case, the article should say something to reconcile the difference between what he is usually referred to as (I don't know) and what he called himself. Shreevatsa (talk) 02:49, 29 December 2008 (UTC)

I just did a search in Google scholar, and Megh Nad, or M.N. seems to be what he used for his articles. Interestingly, other people tend to refer to him as "Meghnad". Also, typically in Bengali, the name is written as a single word মেঘনাদ, rather than মেঘ নাদ.

I think we can use the spelling used by the subject himself, and give an explanation at the top of the article about alternate spellings. --Ragib (talk) 02:58, 29 December 2008 (UTC)

An explanation for deleting a reference based on a newspaper only

“It is said that the prize committee was of the opinion that one winner in a century from India was more than what Physics could tolerate”

-I have deleted this statement based on just a newspaper (however trustworthy otherwise) entry, as the author Dwaipayan Ghsoh Dastidar, does not cite any reference for the claim he made in that article [was noted here as reference no. 19 --> http://indiatoday.intoday.in/story/scientists-from-india-seldom-get-their-due/1/204028.html] .

Going to this link: http://rsnr.royalsocietypublishing.org/content/61/3/333.full, - “India's Physics and Chemistry Nobel Prize nominators and nominees in colonial and international context” by Rajinder Singh does not mention any such malpractices on any of the nominator’s part. In fact, the American physicist A. H. Compton was the only person to nominate him (M.N.Saha) more than once.

The table there-in (the article mention above by Singh) might also be of some value to dispel these kinds of misconceptions of every deserving Indians as either victimised or being under a conspiracy, when it involved the Nobel Prize, excluding maybe the possibility of the recent one involving E. C. G. Sudarshan.

I would certainly like this reference and this statement “It is said that the prize committee was of the opinion that one winner in a century from India was more than what Physics could tolerate” to find its due place in the article here, if the author Dwaipayan Ghsoh Dastidar, does cite any reference, other than just that one liner he stated in his authored article.

Otherwise it’s just sensationalistic journalism, and lousier wiki-spamming, possibly not much difference to the recent Shouryya Ray episode.

More copyright woes

When I read the article, my suspicions were aroused by the style and tone, so I ran a Gsearch using several strings, and found the similarities too stark. I found: "After B.Sc. came M.Sc. and once again S.N. Bose was his classmate" came from Venkatraraman (pg 3). I don't know how much more there is, but where there is one plagiarised sentence in an article, there are usually plenty more. For your information, there is also "Meghnad got involved with Anushilan Samiti to take part in freedom fighting movement", which is lifted straight out of Venkatraraman (pg 5), and there may be more lifted from this source. And apparently huge chunks were copied from this attributed source. I'm not sufficiently interested in the topic to want to go researching it. However, if anyone can help clean it up, that would be great. Bearing in mind the potential scale of the problem, and the legacy violation, I suspect the best way forward may be a complete rewrite. But I would advise against removing the tag without having surveyed the problem in detail and done the necessary repairs. -- Ohconfucius ^{ping / poke} 07:49, 13 April 2013 (UTC)

While I could not see the page you flagged, I spot-checked the text added in the series of expansion and in this edit checked the words "However Maxwell's theory also predicted that when the size of the object is reduced, the pressure decreases". It brings the same book you flag, page 56. A text comparison reveals the following:

Source text

Article text

The idea of radiation pressure was by itself not new. It was a natural consequence of Maxwell's electromagnetic theory of light, and laboratory experiments had already been performed to demonstrate the existence of radiation pressure. However Maxwell's theory also predicted that when the size of the object is reduced the pressure decreases, becoming vanishingly small when the size dwindles to that of an atom.

The source differs from the text in the article by small matters of punctuation and capitalization until you hit those three added words. Given this and your findings, I have reverted this and will notify the contributor in case he is the author of the 1995 book or otherwise able to verify compatible license. --Moonriddengirl ^(talk) 17:11, 14 April 2013 (UTC)
