elaborate on the "unsolvable" problems
The article says that Dantzig solved two problems that were initially believed to be unsolvable, but makes no mention of what those two problems were. Could someone with expertise in this field please consider adding details about those two problems? --Ixfd64 (talk) 05:43, 5 September 2008 (UTC)
- I’m not an expert on this topic, but with a little googling around I found the following article , which mentions following facts:
- Dantzig solved those problems in year 1939
- Six week later Dantzig’s professor has prepared one of his two “homework” proofs for publication
- The second problem was not published (except in Dantzig’s PhD thesis) until after the WWII, when another mathematician, Abraham Wald, rediscovered the proof, and they co-published the paper together in The Annals of Mathematical Statistics.
- These facts lead me to believe that the two papers were “Dantzig, G. B. (1 June 1940). "On the Non-Existence of Tests of "Student's" Hypothesis Having Power Functions Independent of σ". The Annals of Mathematical Statistics 11 (2): 186–192. doi:10.1214/aoms/1177731912. ISSN 0003-4851. JSTOR 2235875. ”, and “Dantzig, G. B.; Wald (1 March 1951). "On the Fundamental Lemma of Neyman and Pearson". The Annals of Mathematical Statistics 22 (1): 87–93. doi:10.1214/aoms/1177729695. ISSN 0003-4851. JSTOR 2236704. ”, and thus the two problems are:
- For a family of iid normal random N(μ,σ²) variables with unknown mean and variance, find a test with power function independent of σ. (The answer to this problem is negative: no such test exists).
- (The second is trickier and I cannot quite figure out how to put it in terms simple enough that it could have fit on a blackboard).

- How famous were these problems? The obituary (perhaps with some embellishment?) calls them "two of the most famous unsolved problems in statistics". The Snopes article quotes Dantzig himself calling them "two famous unsolved problems in statistics". But the second wasn't even published until several years later when someone else proved it.... If they were both so famous, a delay seems very strange, especially since his professor wrote up and submitted the first one on his own. 126.96.36.199 (talk) 08:20, 1 May 2011 (UTC)

What does this mean
In the Biography section it says "Early in the 1920s the family moved over Baltimore to Washington." What has Baltimore to do with anything? The family was in Oregon. Is it trying to say "Early in the 1920s the family moved to Baltimore and then to Washington"? -- SGBailey (talk) 20:14, 15 August 2010 (UTC)
"George Dantzig was born in Portland, Oregon, and with his middle name "Bernard" named after the writer George Bernard Shaw. "
Not just his middle name, it appears. George Bernard Dantzig, George Bernard Shaw.
