Until 1939 Tarski was a full-time Warsaw high-school teacher, and simultaneously part-time University researcher and lecturer in general courses, particularly for teachers. Tarski attained worldwide attention as a logician.

Tarski was stranded on a lecture tour in the US when the Nazis invaded Poland in 1939. After some hard years he became a professor at Berkeley and founded the world's leading program of logic research. He was the external examiner for my PhD at Regina in 1970.

New information will soon be available for you.

Three Goals Alfred Tarski Early Work in Poland: Geometry and Teaching with a Bibliographic Supplement (1) Translate and provide background for some of Tarski's early work on geometry. With this, all his geometry is now in English. (2) Translate and provide background for all Tarski's work that remained only in Polish. Now, all his work is available in English, French, or German. (3) Update Steven Givant's 1986 Tarski bibliography.

Our book doesn t supplant the Fefermans' wonder ful biography of Tarski, but supplements it.

Cultural remarks Tarski s single axiom D for defining a well-ordered set <Z, R> : ( œ U f Z) ( =/ U (!a 0 U)(œ u 0 U) u R a )

8 December 1924 Warsaw Philosophical Institute Jan Łukasiewicz, On a Certain Way of Understanding the Theory of Deduction, Przegląd filozoficzny 28 Listener s notes? (1935)

Game: Construct Boolean formulas with tiles. Construct proofs using modus ponens and substitution. Łukasiewicz: Deduction has to do with form, not content. Game should be expanded to incorporate œ,. Tarski: This suggests the possibility of "geometric" consistency proofs. Leśniewski: Here is a recursive definition of formula. This shows ( ) not needed.

Some Impact Łukasiewicz officially introduced Polish notation in 1929. 1962 Wff'n Proof game by Layman E. Allen based on the 1929 idea. Allen told me he hadn't known about the 1924 game. Reverse Polish notation now in common use.
