Warsaw School Of Mathematics
Warsaw School of Mathematics is the name given to a group of mathematicians who worked at Warsaw, Poland, in the two decades between the World Wars, especially in the fields of logic, set theory, point-set topology and real analysis. They published in the journal ''Fundamenta Mathematicae'', founded in 1920—one of the world's first specialist pure-mathematics journals. It was in this journal, in 1933, that Alfred Tarski—whose illustrious career would a few years later take him to the University of California, Berkeley—published his celebrated theorem on the undefinability of the notion of truth. Notable members of the Warsaw School of Mathematics have included: * Wacław Sierpiński * Kazimierz Kuratowski * Edward Marczewski * Bronisław Knaster * Zygmunt Janiszewski * Stefan Mazurkiewicz * Stanisław Saks * Karol Borsuk * Roman Sikorski * Nachman Aronszajn * Samuel Eilenberg Additionally, notable logicians of the Lwów–Warsaw School of Logic, working at Warsaw, have i ...

Wolna Wszechnica Polska
Free Polish University ( pl, Wolna Wszechnica Polska), founded in 1918 in Warsaw, was a private high school with different departments: mathematics and natural sciences, humanities, political sciences and social pedagogy. From 1929, its degrees were equivalent to those of university. In the years 1919–1939 the institution employed 70–80 professors. In the academic year 1938/39 educated about 3000 students. The university conducted clandestine courses during the German occupation, but after the war, its activities were not resumed. :pl:Wolna Wszechnica Polska The university was disbanded in 1952.

The Mathematical Intelligencer
''The Mathematical Intelligencer'' is a mathematical journal published by Springer Verlag that aims at a conversational and scholarly tone, rather than the technical and specialist tone more common among academic journals. Volumes are released quarterly with a subset of open access articles. Springer also cross-publishes some of the articles in ''Scientific American''. Karen Parshall and Sergei Tabachnikov are currently the co-editors-in-chief. History The journal was started informally in 1971 by Walter Kaufman-Buehler, Alice Peters and Klaus Peters. "Intelligencer" was chosen by Kaufman-Buehler as a word that would appear slightly old-fashioned. An exploration of mathematically themed stamps, written by Robin Wilson, became one of its earliest columns. In 1978, the founders appointed Bruce Chandler and Harold "Ed" Edwards Jr. to serve jointly in the role of editor-in-chief. Prior to 1978, articles of the ''Intelligencer'' were not contained in regular volumes and were sent out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Holocaust In Poland
The Holocaust in Poland was part of the European-wide Holocaust organized by Nazi Germany and took place in German-occupied Poland. During the genocide, three million Polish Jews were murdered, half of all Jews murdered during the Holocaust. The Holocaust in Poland was marked by the construction of death camps by Nazi Germany, German use of gas vans, and mass shootings by German troops and their Ukrainian and Lithuanian auxiliaries. The extermination camps played a central role in the extermination both of Polish Jews, and of Jews whom Germany transported to their deaths from western and southern Europe. Every branch of the sophisticated German bureaucracy was involved in the killing process, from the interior and finance ministries to German firms and state-run railroads. Approximately 98 percent of Jewish population of Nazi-occupied Poland during the Holocaust were killed. About 350,000 Polish Jews survived the war; most survivors never lived in Nazi-occupied Poland, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treblinka Extermination Camp
Treblinka () was an extermination camp, built and operated by Nazi Germany in occupied Poland during World War II. It was in a forest north-east of Warsaw, south of the village of Treblinka in what is now the Masovian Voivodeship. The camp operated between 23 July 1942 and 19 October 1943 as part of Operation Reinhard, the deadliest phase of the Final Solution. During this time, it is estimated that between 700,000 and 900,000 Jews were murdered in its gas chambers, along with 2,000 Romani people. More Jews were murdered at Treblinka than at any other Nazi extermination camp apart from Auschwitz-Birkenau. Managed by the German SS with assistance from Trawniki guards – recruited from among Soviet POWs to serve with the Germans – the camp consisted of two separate units. Treblinka I was a forced-labour camp (''Arbeitslager'') whose prisoners worked in the gravel pit or irrigation area and in the forest, where they cut wood to fuel the cremation pits. Between 1941 and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warsaw Ghetto
The Warsaw Ghetto (german: Warschauer Ghetto, officially , "Jewish Residential District in Warsaw"; pl, getto warszawskie) was the largest of the Nazi ghettos during World War II and the Holocaust. It was established in November 1940 by the German authorities within the new General Government territory of occupied Poland. At its height, as many as 460,000 Jews were imprisoned there, in an area of , with an average of 9.2 persons per room, barely subsisting on meager food rations. From the Warsaw Ghetto, Jews were deported to Nazi concentration camps and mass-killing centers. In the summer of 1942, at least 254,000 ghetto residents were sent to the Treblinka extermination camp during under the guise of "resettlement in the East" over the course of the summer. The ghetto was demolished by the Germans in May 1943 after the Warsaw Ghetto Uprising had temporarily halted the deportations. The total death toll among the prisoners of the ghetto is estimated to be at least 300,000 kill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
