Untitled[edit]

I don't agree with the merge suggestion -- Hermann deserves his own article. It just needs to be rearranged, expanded, and wikified... Ezrarez 20:36, 8 March 2006 (UTC)[reply]

Should this be History of...?[edit]

Would this page be better as a history of the CMB, rather than just the discovery? By this, I mean so that it includes a discussion of the various predictions of the CMB temperature, before the discovery, then going on to discuss the major events forrowing the initial discovery - such as COBE, WMAP etc. It would be able to take content from the history section of the Cosmic microwave background radiation, which is starting to get rather long. If so, then I would suggest that the page be relocated to History of the cosmic background radiation, or possibly History of the CMB. Mike Peel 12:46, 19 March 2006 (UTC)[reply]

An Earlier Qualitative Prediction[edit]

Phil said: "I very much disagree that a qualitive prediction has no value. Sometimes one has to do some experiments to get the numbers to plug into equations so that he can make quantitative predictions. Consider Cavendish's experiment which result allowed one to calculate G. This particular experiment had no expected experimental outcome. It was conducted to discover something."

Jonathan said: http://upload.wikimedia.org/wikipedia/en/f/f8/Milne_Model.jpg When Milne predicted "The particles near the boundary tend towards invisibility, as seen by the central observer, and fade into a continuous background of finite intensity." This has been ignored because Milne did not predict that the finite background would correspond to blackbody radiation right around 2.7 Kelvin. Hence, though he published this in 1935, it is completely left off the timeline. —Preceding unsigned comment added by 64.6.6.13 (talk) 14:54, 17 April 2009 (UTC)[reply]

External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on Discovery of cosmic microwave background radiation. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20040816231557/http://www.cr.nps.gov/history/online_books/butowsky5/astro4k.htm to http://www.cr.nps.gov/history/online_books/butowsky5/astro4k.htm

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Shifting Bibliography to References + External links; why were the early measurements missed?[edit]

The history of science is similar to science, in that inline citations - see Wikipedia:Citing_sources#Inline_citations - are more useful for checking individual claims rather than general texts that require much more work from the reader/verifier/Wikipedian. It seems to me that most of the references presently in Bibliography should be shifted to either References when used for inline citations, or to External links if they are generally interesting for a wider context, or removed if they don't add any more evidence for the historical claims. The article at the present has a bit of the "let's tell an exciting, appealing story" aspect of popular science. But this is an encyclopedia, not a blog. :). Let the facts speak for themselves about the excitement. Boud (talk) 12:02, 15 January 2018 (UTC)[reply]

Historical details of pre-Penzias-Wilson measurements and their re-discovery[edit]

What is missing, and would be interesting from the historical point of view, is evidence for or against Penzias, Wilson, Dicke, Peebles being aware of Adams/McKellar's 1941 measurement and Le Roux's 1955 measurement. The reference given in Cosmic_microwave_background#Microwave_background_radiation_predictions_and_measurements is a book by Kragh. A search in the ADS http://cdsads.u-strasbg.fr/abstract_service.html might find a specific publication by Le Roux to justify this. See the timeline on the main CMB article for details that historians should be able to analyse. Boud (talk) 12:02, 15 January 2018 (UTC)[reply]
