Talk:Dennis W. Sciama

message: I'm removing the claim that Sciama introduced the idea of dark matter.
Fritz Zwicky inferred the existence of dark matter and apparently coined the term in 1933, when Sciama was 7 years old.  See for instance this review article:
.  I'm also a bit skeptical about the claim that Sciama introduced the idea of multiple universes; it's unclear exactly what idea is being ascribed to him there, but I'm leaving it for now.  To whoever put that claim in the article, it would be great if you could find a source to cite for that (the original paper by Sciama if possible).  It's really useful to have links to scientific papers of historical importance in Wikipedia. --Reuben 04:50, 16 August 2005 (UTC)

replies: text: Yes, except there is nothing at that stub to merge which is not said better here.  It should be speedied with a friendly note in the author's user page pointing him at this article.  Not to mention the importance of spelling the subject's name correctly! ---CH 01:25, 27 March 2006 (UTC)

message: I created the original version of this article and had been monitoring it, but I am leaving the WP and am now abandoning this article to its fate.
Just wanted to provide notice that I am only responsible (in part) for the last version I edited; see User:Hillman/Archive.
I emphatically do not vouch for anything you might see in more recent versions, although I hope for the best.
Good luck in your search for information, regardless!---CH 23:19, 30 June 2006 (UTC)

message: Missing from References is this item which I would consider very important:
Alexander Unzicker, 'Einstein's Lost Key: How We Overlooked the Best Idea of the 20th Century' (2015) where references to Sciama appear on pp. 8-9, 114, 134-136, 146-147, and 172. 
For that matter, it seems that Unzicker's showcasing of Sciama's ideas should be mentioned also in the text of article itself.
