Rmm-Traian Lalescu a Tribute
www.ssmrmh.ro A TRIBUTE TO TRAIAN LALESCU AN OUTSTANDING ROMANIAN GREAT SCIENTIST By D.M.Bătinețu-Giurgiu,Neculai Stanciu-Romania (Born on July 12, 1882 – Died on June 15, 1929) Traian Lalescu’s Problem – Published in Romanian Mathematical Gazette, Vol. VI, 1900-1901, as problem 579, p. 148. Problem 579. Compute the limit: ( + )! − √! → Solution: !≅ ⇒ √!≅ + ( + )! − √ = − = → → RMM-TRAIAN LALESCU www.ssmrmh.ro Traian Lalescu started in this world from Bucharest on July 12, 1882 and there he would find his premature end on June 15, 1929. His father, a modest bank clerk, had the same first name, Traian and was originally from Cornea commune, Caraş-Severin county. In 1876 he wrote a paper on the economic problems of agriculture and another, "The agenda of popular banks and the Lalescu coefficient method", which can be found at the Library of the Romanian Academy. His mother was from the Transylvanian side. The scientist presented himself as a native of the village near Caransebeș. He begins his primary education in his native Bucharest. The first two middle school classes in Craiova. He took the next two middle school classes in Moldova, at Roman, then studied high school at the Boarding School in Iaşi. His name is inscribed on the high school honor roll. Traian Lalescu has always had the imprint of the environment so varied in which he was formed due to the childhood pilgrimages he made with his family: he was as solid as Banat, talkative as Olten, serious as Transylvanian, beautiful lover as Moldovan and with the sprinting spirit like the one from Bucharest. -
Mathematics Education in Romanian at Babes-Bolyai University Cluj
Stud. Univ. Babe¸s-Bolyai Math. 59(2014), No. 4, 399–418 Mathematics education in Romanian at Babe¸s-Bolyai University Cluj-Napoca Dorel I. Duca and Adrian Petru¸sel Abstract. In this paper, we will present the most important moments of the evolution and development of the mathematical education and research activities in Romanian at Babe¸s-Bolyai University Cluj-Napoca. The main figures of the mathematical university staff are also presented. Mathematics Subject Classification (2010): 01A72, 01A73, 01A70. Keywords: University of Cluj, Babe¸s-Bolyai University, Faculty of Sciences, Faculty of Mathematics. 1. A short walk through the history of the university education in Cluj On May 12, 1581 the prince S¸tefan Bathory decided to set up at Cluj a college with three faculties: Theology, Philosophy and Law. This is the first official attestation of a higher education institution in our city. After some climbings and descents and a contradictory evolution of the higher education in Cluj, on October 12, 1872 the emperor Ferenc J´ozsef approves a decision of the Hungarian Parliament for setting up the University of Cluj. This Hungarian university have had four faculties: Law and State Sciences, Medicine, Philosophy, Letters and History and, the last one, Mathematics and Natural Sciences. During this period some pre-eminent mathematicians (such as Gyula Farkas, Lip´otFej´er,Frigyes Riesz or Alfr´ed Haar) have had essential contributions to the development of the Cluj mathematical school. The great wish of the Romanian nation to have their own university with com- plete studies in Romanian was finally accomplish after the union of the province of Transylvania with the Romanian principality in 1918. -
Grigore C. Moisil: a Life Becoming a Myth
International Journal of Computers, Communications & Control Vol. I (2006), No. 1, pp. 73-79 Grigore C. Moisil: A Life Becoming a Myth Solomon Marcus “All what is correct thinking is either mathematics or feasible to be transposed in a mathematical model.” Grigore C. Moisil (1906 - 1973) Grigore C. Mosil, Romanian mathematician, Professor at the University of Bucharest - Faculty of Math- ematics and Computer Science, member of the Romanian Academy, member of the Academy of Sciences in Bologna and of the International Institute of Philosophy, Computer Pioneer Award of IEEE Computer Society (IEEE - 1996). Grigore C. Moisil belongs to the fifth generation of Romanian mathematicians. The first generation includes the founders Spiru Haret and David Emmanuel, both with doctorates at Sorbonne (Paris). They were born at the middle of the XIXth century and have the merit to initiate the high level mathematical research in Romania. (We leave aside Transylvania, with Janos Bolyai, who already in the first half of the XIXth century discovered non-Euclidean geometry). The second generation includes the first Romanian mathematicians with a long career of scientific research: Gh. ¸Ti¸teica,D. Pompeiu (both with doctorates at Sorbonne), Al. Myller and Vera Myller (both with doctorates at Gottingen, Germany). They had already an important impact on Moisil’s formation as a mathematician. The third generation includes Victor Valcovici, Traian Lalescu and Simion Stoilow (considered as the most important Romanian mathematician until the sixties of the XXth century), born in the eighties of the XIXth century. Lalescu died very young (in 1929), but Valcovici and Stoilow became great professors not only before, but also after the second world war. -

History of Informatics. From recursivity to the Turing universal machine and Horn clauses Marin Vlada1, Adrian Adăscăliţei2 (1) University of Bucharest, 14 Academiei Street, RO-010014, Romania (2) ”Gh. Asachi“ Technical University, 67 “D. Mangeron” Blvd., Iaşi, Romania E-mail: vlada[at]fmi.unibuc.ro, adrian.adascalitei[at]yahoo.com Abstract The article describes the contribution of Romanian scientists in several fields of scientific research, on the fundamentals of calculus theory, the fundamentals of cybernetics, the algebra theory of automatic mechanisms, the mathematical logic applied to the construction and use of the first electronic computers, etc. In the 1960s, Romania was considered among the first countries in the world (after the USA, England, USSR, Germany, France, Japan, Austria, the Netherlands, Italy, Denmark) on research and efforts to build an electronic computer. The Romanian School of Mathematics developed under the influence of the Romanian mathematicians who supported their doctorates with prestigious mathematicians from France, Germany, and Italy. Mathematician Gabriel Sudan (1899-1977) published in 1927 (before W. Ackermann, 1928) the first recursive function that is not primitive recursive. Dr. Ştefan Odobleja (1902-1978) - a professional military doctor, is one of the forerunners of generalized theoretical cybernetics and Artificial Intelligence, the author of "Consonant Psychology," published in Paris for the first time in 1938. In the 1950s, Grigore Moisil (1906-1973) developed a new theory of finite automata and proposed what is known today as "Łukasiewicz–Moisil algebras" and which Gr. Moisil applied to the logic of commutation circuits, which is an important contribution to the development of computer science. Keywords: Computation, Recursive function, Turing machine, Computer System 1 Contribution of Romanian scientists to the appearance of electronic computers Motto:“Sciences and theories have an evolution and development, but also a dynamic of concepts and terms that can change through new meanings and new valences. -

NEW ECONOMY Section 151 152 150 YEARS OF ROMANIAN RESEARCH Anda GHEORGHIU∗ Abstract. Internationally, Romania is rather less known for his achievements in the scientific field. Although it has memorable contributions to the advance of the global science, there are few persons who truly are aware of the great value of science accomplishments generated by Romanians. The motivation of this article lies in the desire to make known to the global academic community some of the most significant scientific discoveries of Romanians. Since ancient times, the Romanian principalities (Transylvania, Moldavia, Wallachia) tried to develop a system of knowledge in various fields, such as mathematics, astronomy, engineering mining, milling, medicine. But very few people were truly educated mostly priests, and royal functionaries. Schools of higher education – had existed in the Romanian principalities since the 16th century. The most dynamic and continuing were the “academies” set up in Bucharest (in 1689) and Iasi (in 1707). A program of modernization was adopted after the 1859 Union of the two Romanian Principalities, Wallachia and Moldavia. Universities, commercial, medical and technical schools were established. Many important intellectuals surprised the world with their scientific discoveries. 2016 marks the 150-th anniversary of the founding of the Romanian Academy and 150 years since King Carol I (Hohenzollern Sigmaringen) ascended to the throne of Romanian principalities. A king who had not only military, political and social achievements, but above all, a big role in the advancement of the Romanian culture, technology, infrastructure. This paper is an attempt to present to the public some of the most important achievements of the Romanian scientist in the 150 years. -

Gheorghe Tzitzeica - an Incomplete Bibliography
Gheorghe Tzitzeica - an incomplete bibliography Gabriel Teodor Pripoae and Radu Gogu Abstract The aim of this paper is to provide the reader with: the list of scientific papers and books of Gheorghe Tzitzeica; a record with miscellanea papers (in elementary Mathematics, Educational policy, etc); a bibliography with papers quoting Gheorghe Tzitzeica (in the title, in the key words or in the references list). Both the second and third items are inevitably incomplete, as the subject is too vast, the sources are scarce and erodate in time. Mathematics Subject Classification: 01-02. Key words: Tzitzeica’s papers, Tzitzeica’s bibliography, Tzitzeica’s quotations. The mathematical and cultural work of the Romanian geometer Gheorghe Tzitzeica is a great one, because of its importance, its originality but also due to its dimensions: more than 200 printed papers and books with numerous editions (the problem book in geometry has more than 12 editions). In 1941, two years from the passing into the eternity of Gh. Tzitzeica, the Ro- manian Academy published the first volume of his work, containing a selection of scientific papers and memoirs, through the efforts of Gh. Vr˘anceanu (the succesor of Tzitzeica at the Chair of Geometry of the University of Bucharest) and O. Onicescu. In the Foreword of the respective volume, D. Pompeiu described the project of the Romanian Academy to publish also: - a second volume with the second editions of The projective differential geometry of webs (1923) and Introduction to the projective differential geometry of curves (1931); - a third volume with miscelanneus papers. After more than 60 years, this project is only partially accomplished: the new edition of The projective differential geometry of webs appeared in 1956, but the third volume is still a (forgotten) dream.
