Betti, Lukasiewicz and Lesniewski on Contradiction RTF file (33 Kb) A.Kanik, Contribution of Lukasiewicz's Philosophy to Conventionalism Other Links in the World A short biography edited by the MacTutor History of Mathematics archive Presentation Jan Lukasiewicz is known all over the world as the founder of the first non-classical logical calculus, the so-called trivalent or polivalent logic, and as one of the most prominent and significative logicians of this century. But he was also very active in historical research on logic, giving a new and up-to-date interpretation of Aristotle's syllogism and of the Stoics' propositional calculus. His activity is strictly connected to the school founded by Kazimierz Twardowski, whose first pupil he was in Lvov . Maybe less known, but very significant, was his philosophical reflection about science and the role that creativity plays in the invention of theories, regarding which he followed an anti-inductive attitude in many aspects similar to Popper's conceptions.

Lukasiewicz Jan Lukasiewicz [ ] was one of the mid-twentieth century's many luminescently creative middle-European mathematicians. This "Postfix Notation Mini-Lecture" [ ] explains some of his relevance to the theory of computing languages. "PN" in this context can mean either "Postfix ..." or "Polish ..." It's possible that Knuth and HP, in different ways, had hands in popularizing the "Polish ..." reading.
