Polish mathematicians Jan Lukasiewicz (born 21 December 13 February ) was a mathematician born in Lwów Galicia (now L'viv Ukraine ). His major mathematical work centred on mathematical logic . He thought innovatively about traditional propositional logic , the principle of non-contradiction and the law of excluded middle multi-valued logics , including his own three-valued propositional calculus, the first non-classical logical calculus . He is responsible for one of the most elegant axiomatizations of classical propositional logic; it has just three axioms and is one of the most used axiomatizations today. He also pursued philosophy, approaching the human aspects of scientific theory-making with ideas similar to those of Karl Popper Polish notation of 1920 was at the root of the idea of the recursive stack a last-in, first-out computer memory store invented by

Jacques Maritain Center: Thomistic Institute Faith, Reason, and Logic Roger Pouivet Institut de Philosophie F-35700 Rennes (France) roger.pouivet@univ-rennes1.fr As everybody knows, Pope John-Paul II is Polish. In his encyclical, Fides et Ratio , he renews the recommendations of Pope Leon XIII in favor of Thomas Aquinas' philosophy and theology. He quotes a number of Thomists, among them Jacques Maritain and Etienne Gilson; but, rather curiously, the Polish Pope doesn't speak about a very interesting group of Polish Thomists, often referred to as the Cracow Circle. The fact that the philosophical background of John Paul II is mainly phenomenological constitutes only an anecdotal explanation of this omission. Probably the main reason for it is that the encyclical isn't meant to be a philosophical study, and the Pope isn't trying to give an overview of a philosophical topic to be published in an encyclopaedia; he is merely concerned to convey the doctrine of the Church. Nevertheless, I think that it may prove interesting to examine the Cracow Circle's Thomistic stand on the subject of faith and reason I shall maintain that it reflects a serious confusion between rationality and logic, despite my view that the Cracow Circle numbered among its members several excellent, and important, philosophers.

When using Polish notation, the instruction (operation) precedes the data (operands). In Polish notation, the order (and only the order) of operations and operands determines the result, making parentheses unnecessary. The notation for the expression 3(4 +5) could be expressed as x 3 + 4 5 This contrasts with the traditional algebraic methodology for performing mathematical operations, the Order of Operations. (The mnemonic device for remembering the Order of Operations is "Please Excuse My Dear Aunt Sally" - parentheses, exponents, multiplication, division, addition, subtraction). In the expression 3(4+5), you would work inside the parentheses first to add four plus five and then multiply the result by three. In the early days of the calculator , the end-user had to write down the results of their intermediate steps when using the algebraic Order of Operations. Not only did this slow things down, it provided an opportunity for the end-user to make errors and sometimes defeated the purpose of using a calculating machine. In the 1960's, engineers at

I would like to discuss this book and present some of its contents. I hope that I can interest you in learning more about it. 1. Tributes For many years my own knowledge of the book was based on three brief accounts of it. In 1975 I read an article by Boleslaw Sobocinski , written at the time of Lukasiewicz's death. Speaking of this book, he says: He goes on to say that on its logical side the book is dated and sometimes in error; for our knowledge and understanding of logic have grown, partly of course in consequence of Lukasiewicz's own later discoveries. Because Sobocinski's article is admittedly a eulogy of Lukasiewicz, we must read it with some caution to filter out some of its excessive enthusiasm. Later in 1975 I was reading the philosophical autobiography of Stanislaw Lesniewski, where I found the following:

The Rationale for Analog Truth Value Operations in the History of Logic Origination The Greeks developed logic out of a need for their orators to gain a verbal advantage over their rhetorical opponents. Yet not until Aristotle (384 to 322 BC) wrote a book covering the art of discourse called the Organon (meaning instrument or tool) was the methodology of logic clearly defined. Michael Grant (1989) says this about it: "The most significant parts of the Organon are the Prior and Posterior Analytics, containing two books each. The former work reviews the general principles of inductive inference, while the Posterior Analytics applies these methods of proof and definition to the nature and validity of knowledge (epistemology), indicating that there is a proper method of constructing generalizations, applicable to all the sciences, and explaining how language can and should be employed for this purpose." "Aristotle stresses the novelty of his logical writings and even if, contrary to what has sometimes been claimed, he did not invent the discipline of logic (since Parmenides and the sophists and Plato had prepared the ground) he was perhaps the first to comprehend the importance, not only of the content of statements, but of their form, and their formal relation to each other. This was a major breakthrough, for no one had ever before offered a general account of what is valid in argument and what is not."

Lotfi Zadeh: Fuzzy logic-Incoporating Real-World Vagueness By Pragya Agarwal Back to Classics Background Fuzzy logic was first invented as a representation scheme and calculus for uncertain or vague notions. It is basically a multi-valued logic that allows more human-like interpretation and reasoning in machines by resolving intermediate categories between notations such as true/false, hot/cold etc used in Boolean logic. This was seen as an extension of the conventional Boolean Logic that was extended to handle the concept of partial truth or partial false rather than the absolute values and categories in Boolean logic. Philosophers such as Plato had posited the laws of thought and one of these thoughts was the Law of Excluded Middle . Parminedes proposed the first version of this rule around 400 B.C. and stated amidst controversy that statements could be both true and not true at the same time. The Greek Philosopher Plato laid the foundations for the fuzzy logic by proposing a third region between true and false where the two notions tumbled together. In the early 1900s, Lukasiewicz extended on to the conventional bi-valued logic of Aristotle and proposed a tri-valued logic in his paper in 1920 titled On three-valued logic The fuzzy set theory was introduced by Professor Lotfi Zadeh in 1965 and can be seen as an infinite- valued logic. Lotfi Zadeh is currently serving as a director of BISC (Berkeley Initiative in Soft Computing). Prior to 1965 Zadeh's work had been centered on system theory and decision analysis. Since then, his research interests have shifted to the theory of fuzzy sets and its applications to artificial intelligence, linguistics, logic, decision analysis, control theory, expert systems and neural networks. Currently, his research is focused on fuzzy logic, soft computing, computing with words, and the newly developed computational theory of perceptions and natural language.

Attempts by industry and government to prevent the loss of its cargo of Bunker C oil were unsuccessful. Clean-up efforts lasted for the next two years and cost about $4,500,000, but had little useful effect. Thirty-two years later, in June 2002, Environment Canada conducted a three-day training exercise in Chedabucto Bay, and discovered considerable evidence of the wreck of the Arrow. The Liberian-registered tanker, under charter to Imperial Oil Ltd., had been carrying 108,000 barrels of crude oil to Nova Scotia when it sank in high winds and heavy seas.

Home Site Map Tadeusz Kotarbinski from Reism to Pansomatism "I reached the chair of philosophy via logic. Teaching logic became the field of my activity as a university professor of philosophy, a member of other humanistic faculties. Emphasis is here placed on the words 'teaching' and 'humanistic'. For my lectures and classes were conceived as an organon in the classical sense of the term, for philosophers as well as for those who, having completed their course of study, would espouse the cause of disseminating humanistic knowledge and thinking, particularly future secondary school teachers. Somewhat later my activity embraced also law students. My linguistic equipment proved to, be very helpful in this respect. For it seems especially important when the problems of an organon of this kind are conceived historically and is quite crucial when pondering the original Organon of Aristotle (or to be more cautious, of the peripatetic school) and its continuators. Conceived in this manner logic was by no means confined to formal logic, but came to comprise the problems of epistemology, semantics and methodology. It is precisely the latter problems - not those of formal logic - that were of particular interest to my mind. Nevertheless, I felt bound to contribute to the study of formal logic. The feeling was encouraged both by my colleagues at Warsaw University and by my awareness of the precise phase that logic had reached in its historical development. It was precisely the moment when mathematical logic was triumphantly entering the scene. The names of Frege, Bertrand Russell, Peano, Burali-Forti, Couturat and many others were on everybody's minds.
