Talk:Alfred Tarski

message: There's a new biography of Tarski out and it looks pretty interesting.  Maybe someone who's read it can update the wp article, or at least add a reference.  I may pick it up soon.  After the success of A Beautiful Mind maybe we're in for a spate of lurid math biographies.
:The biography is Feferman and Feferman 2004, already cited in the references and now mentioned in the article.  I have a copy now and will try to add some biographical material to the wp article if nobody else does it first.
:I too own a copy of F&F 2004. It reveals that Tarski indeed had a far more interesting life than John Nash. It is also lurid; Tarski was a classic case of the Richard Wagner syndrome: "I am a genius and geniuses are exempt from the usual moral rules." An unusual proportion of Tarski's Ph.D. students were women, but his respect for their ability to do math was seldom the sole explanation.202.36.179.65 23:38, 10 March 2006 (UTC)
replies: text: Don't let us slander the ladies. We can list them and cross reference them and if they don't come up red links, we can conclude that they did make contributions. Even the red links should be looked at since non-methematical/scientific factors have sometimes affected the reputation of women in STEM, e.g. most notoriously, Lise Meitner and the Nobel Prize.

message: Much of the material in section (4)-(6) is a review of recent polemics in the philosophy literature, about which the jury is still out; hence Wikipedia is not the right place for such material. Moreover, it's not that well written. It should be replaced with a careful concise exposition of the content of Tarski's best known papers. Tarski's theory of truth, by the way, deserves its own entry.
Smullyan has convinced me that much of the hoopla attending the results of Godel (1931) should instead be accorded to Tarski's Indefinability Theorem (TIT). TIT is not tied to Peano arithmetic, and for that reason its philosophical value is more evident. Moreover, TIT is much easier to prove than Godel's results (although Smullyan has shown that these too are not as hard to prove as people think). Proving TIT requires a bare minimum of syntactic machinery, plus the trick called diagonalisation. I invite someone versed in metamathematics to add a paragraph to this entry fleshing out what I say here.
  
I've done what I could with Tarski the mathematician and logician, and invite others to do more. But anyone doing so had better have done graduate work in the area, and have a copy of Feferman and Feferman at her side! BTW, Tarski's students Steve Givant and Roger Maddux are good expositors of Tarskian mathematics.202.36.179.65 00:21, 11 March 2006 (UTC)

thread_title: Some suggestions

message: On some places year of birth is 1901, but on some places is 1902. What is true year? Date is January 14, but for year of birth I am not sure. Can anyone help about that? --Djordjes (talk) 08:12, 5 June 2006 (UTC)
replies: text: Feferman & Feferman p. 5 says 1901, with an endnote specifically stating "In some biographical articles, Tarski's birthdate has been given incorrectly as 14 January 1902". 71.141.194.163 (talk) 08:04, 24 January 2008 (UTC)
replies: text: This is very strange. Such a discrepancy could almost be explained by the fact that in 1900/1901 Russia (and therefore Warsaw???) still had the Julian calendar. But from Julian calendar#From Julian to Gregorian it looks as if the difference at the time was only 13 days! Another explanation could be the boring "first day of the century" debate. --Hans Adler (talk) 15:25, 24 January 2008 (UTC)
replies: text: Probably just a transcription error someone made somewhere along the way.  A little weirder, the German title of the Warheitsbegriff paper mismatched the bibliography entry in F&F.  The version that I just changed in the article appeared to be a direct translation of the Polish title (the concept of truth in the language of deductive disciplines; instead of ... in formalized languages).  F&F's citation is Studia Philosophica 1, pp. 261-405.  Was there a different German translation in 1936? 75.62.108.101 (talk) 10:26, 29 January 2008 (UTC)

message: I will slowly, as time permits, switch to the more standard (at least on Wikipedia) system of footnotes for references. The current parenthetical referencing is not ideal in such a long article because readers have no easy way to go back and forth between the text and bibliography. Anyone who feels like helping out is more than welcome to do so. I suspect that, along the way, I'll make the article messier but once it's done, it should be an improvement. I'm trying to implement the system used, say, in the recently featured Albert Speer article. Pichpich (talk) 03:52, 20 December 2008 (UTC)
thread_title:  Slowly switching the references 

message: The article cites an American National Biography series (vol. 21) piece about Tarski, attributed to Anita B. Feferman, but elsewhere there's a cite attributing authorship jointly Anita B. Feferman and Solomon Feferman.  If someone here has access to the volume, can they check the authorship of that article?   There is a separate, book-length 2004 biography of Tarski that was co-authored by both Fefermans, so that may have caused confusion.  Thanks.

message: Today the article by JT Smith in American Mathematical Monthly this year has been added to the Logic bibliography. Smith's article shares his research on Mario Pieri. Apparently Pieri's Point and Sphere memoir was translated into Polish and formed the substance of Tarski's geometry course at University of Warsaw 1926/7, contrary to the "original course" asserted in the text of our article at the moment. I note that there are 66 watchers on this important biography, so caution with the rewrites is in order. I expect that now the reference is posted, one of the usual attendants at this site will make adjustments. Smith notes that Tarski served as examiner at Smith's thesis defense, and at that time Tarski mentioned Pieri. It seems remarkable that such an important source in Tarski's career should appear only now through Smith's penetrating investigation.Rgdboer (talk) 23:43, 24 August 2010 (UTC)
replies: text: Another source is Steven Givant (1999) in Mathematical Intelligencer. Further note that the article Tarski's axioms seems to be the place to discuss Pieri's role in the evolution of Tarski's system, which in fact is original with him.Rgdboer (talk) 03:33, 10 September 2010 (UTC)

message: There is an ambiguity in the statement: "No individuals" in the list of logical notions.  If individuals are NOT among the accepted logical notions, then they should NOT be in this list.  Rather, they should be noted below the list as explicitly excluded, as the intro to the list leads the reader to assume that everything listed IS a logical notion.  Alternatively, the intro to the list needs to be rewritten.  Ross Fraser (talk) 08:45, 20 April 2011 (UTC)

message: If Tarski was born in Poland, then he was born as Alfred Tajtelbaum. Where and when the "Teitelbaum" was in use? If there is no sensible answer to my question, then I prefer deleting "Teitelbaum".--93.86.33.191 (talk) 10:54, 20 April 2017 (UTC)
replies: text: There are numerous cases of slight differences of spelling in proper names in the contested territories of Central and Eastern Europe (e.g. "Stravinsky", "Strawinsky.") We'd have to know more about his parents and family. A note in the German language article on Tarski cites the Feferman biography and says, "both forms of names can be found in the Warsaw archives (Tajtelbaum is the Polish spelling, Teitelbaum is the German spelling with the same pronunciation). His first publications came under the name Tajtelbaum." Pascalulu88 (talk) 20:24, 23 July 2023 (UTC)

message: Whether someone is Catholic, or Protestan, or Muslim. What the meaning? In Poland Jews lived together peacefully alongside Christians and Muslims since the 10th century and they are POLEs. In the English Wikipedia, however, the Jewish religion must always be shown, the other religions not and respect, even if the great, great, great grandparents had something to do with the Jewish faith and had been Catholic for ages or only had one ancestor (100 years ago) of Jewish origin. Isn't that important for you? Is an American with a Christian religion a European or an American, with a Hindu religion an Indian or an American citizen? According to your logic, must still be Indian or European. Then please call the 12 million Americans of Polish origin in Wikipedia as Poles because they had Polish ancestors!
Why not do this when the American Wikipedia labels the Jewish religion as Jewish nationality at every step, even if someone has adopted the Jewish religion by marriage or of their own free will.
Is that science?
The article implies that he and his brother were the first in his family to convert to Catholicism but that Tarski was actually an atheist. The fact that a lot of his relatives died in the Holocaust seems sufficent reason to mention Tarski's previous identity as a Jew. — Preceding unsigned comment added by Pascalulu88 (talk • contribs) 20:29, 23 July 2023 (UTC)
replies: text: This material is adequately represented in the body of the article. As a general rule, we mention citizenship but not ethnicity or religion in the lead, unless those things are central to the notability of the subject (for instance, someone notable as an activist for a minority ethnicity, or notable as a religious leader). —David Eppstein (talk) 20:36, 23 July 2023 (UTC)
