Talk:Alexander Friedmann

message: The following claim:
"This dynamical cosmological model of general relativity would come to form the standard for the Big Bang and steady state theories. Friedman's work supports both theories equally, so it was not until the detection of the cosmic microwave background radiation that the steady state theory was abandoned in favor of the current favorite Big Bang paradigm."
seems to be false. I'll remove it if no one wants to defend it. Gene Ward Smith 22:42, 25 September 2006 (UTC)
replies: text: In 'Cycles of Time', Roger Penrose writes "However, towards the end of my time at Cambridge, detailed counts of distant galaxies carried out at the Mullard Radio Observatory by (Sir) Martin Ryle (also in Cambridge) were beginning to provide clear observational evidence against the steady-state model." (Penrose's italics.) The report Penrose refers to is available online: http://adsabs.harvard.edu/abs/1955MmRAS..67..106S But see also http://en.wikipedia.org/wiki/Second_Cambridge_Catalogue_of_Radio_Sources. Penrose's wording "were beginning to provide" may be a hint at the epistemological complication of using non-conclusive reasoning to infer something that is confirmed only much later by acceptable reasoning. I seem to remember that something of that sort applied to http://en.wikipedia.org/wiki/Solar_eclipse_of_May_29,_1919 as well, but can't remember right now where I read it. --84.177.62.38 (talk) 12:39, 14 November 2011 (UTC)
thread_title:  Claim 

message: The date of his birth is unclear, but if 1888 as the article states and the date of his death was 1996, he did not die at age 84 unless he discovered the secret of using time dialation in his personal life.
I have no knowledge of the accurate dates, but I can add and subtract without paper and a pencil.
So some attention to this arithmetical detail should be devoted.
thanks, a lover of wiki and learning physics.  —Preceding unsigned comment added by 71.146.6.103 (talk) 19:11, 27 November 2007 (UTC)
thread_title:  Dates of birth and death inaccurate?? 

message: Along with the chronological oversight already noted goes the "bomber" business in the opening graph.
Friedman, I am sure, once held the world altitude record for a balloon flight--23,000 feet.  I infer from that that it is a safe bet that he could have flown in the Russian air force--but please, he may have been a bomber PILOT or a bomber CREWMAN, but hardly a "bomber," as stated.  I figured that out w/o pencil or paper too.  :)  Does anyone have the details of his service record?

thread_title:  Bomber What? 

message: Curious, but how could he live most of his life in Leningrad, when the city was named such in 1924.  That was the year before he died.

thread_title:  Professor at Penn State University 

message: ... because this is a very common name, so Alexander Friedmann (physicist) is required. See for instance Alexander Friedman, the architect from Germany who designed important buildings in Jerusalem and was, of course, wrongly linked to this page on List of Jewish architects.

thread_title: Title is inaccurate

message: Under the heading "Professorship", the article mentions "a static eternal Universe as believed in Newton's time".  This is as per the 22 April 2020‎ edit by user 103.21.127.60‎.  It would be good to have a reference to support the prevalence of this idea in Newton's time. Snowfallout (talk) 20:49, 20 January 2023 (UTC)
