For a long time its vast territories were possessed by the great Ottoman, Austro-Hungarian, or Russian empires. In XIX century, however, the empires grew weaker and their military defeats, of which the ultimate was the I World War, allowed for a restoration of old national states and birth of new ones like Bulgaria, Romania, Hungary, Czechoslovakia, Poland, Lithuania, Latvia, Estonia, Russia proper. Ambitious but backward, these states strived to reach the level of more developed countries in Central and Western Europe, then leading cultural and scientific centres. Exact sciences ‒ mathematics, physics, mechanics, astronomy, chemistry ‒ seem to be an area where those struggles for excellence manifested themselves particularly intensely. By their very nature, exact sciences are international in character, but for some time the Central-Eastern Europe was on the receiving side. It was apparent both in long stays of western scientists in Central-Eastern European territories (e.g., S. Lhuillier in Poland, L. Euler and Ch.M. Bartels in Russia, O. Volk in Lithuania) and, more efficiently, in sending young people to leading centres in Western Europe and allowing for development of their talents after return (e.g., professors of Royal University in Warsaw, M.V. Ostrogradski and V.J. Bunjakowski in Russia, W. Bolyai in Hungary). Another instance of this process were voyages of Czech mathematicians to new states of the Balkans (Croatia, Slovenia, Serbia, Bosnia, Herzegovina, Bulgaria), where they served as pioneers of mathematical life there. These examples pertain to mathematics but analogous ones can be offered for other exact sciences as well, including chemistry, where such exchanges were followed by development of domestic chemical industry, e.g., in Poland. After decades of more or less passive assimilation of ideas from the West, the general situation became ripe enough to allow for the birth of local mathematical centres of worldwide distinction. The greatest significance was achieved by two of them: Moscow mathematical school, whose most distinct leader was N. Lusin, and Polish mathematical school with Sierpiński at its head. As a result, the Central-Eastern Europe achieved in XX century the equal footing with the world science. The main motive for organizing a conference devoted to raising the level of scientific culture in backward countries of Central-Eastern Europe was a strong conviction of historical significance of those processes both on a local scale of national cultures and on a global scale of the world science. Perhaps some specific characteristics of that development may serve as a model to adapt in other conditions. The present volume contains lectures and posters presented at the conference “The reception of exact sciences in Central-Eastern Europe in 1850‒1920”, which took place in September 2013 in Cracow, along with other papers related to the subject. The Conference met with substantial interest and hopefully will be continued in the future.

Słowa kluczowe: Uniwersytet Litewski, matematyka, geometria różniczkowa, teoria funkcji, historia matematyki, filozofia matematyki * Juozas Banionis, Lithuanian University of Educational Sciences. 6 1. Introduction In the independent Republic of Lithuania, Otto Theodor Volk became the most prominent scholar in mathematics among professors of Lithuanian University. On 16 February 1922, when Lithuanian University was established, the core of the Faculty of Mathematics and Natural Sciences of the university was created. The rest of the research staff of the faculty was to be formed on a competitive basis. Vacant positions at the faculty were announced in the daily newspaper Lietuva on 22 July 1922. The announcement was also addressed to Universities in Berlin, Munich, Königsberg, Vienna, Tartu, Riga, Zürich, and Helsinki. Among the candidates who applied for the position of a professor of differential equations and higher algebra there was an associate professor doctor O. T. Volk from Munich University1. 2. Beginning of the story of O.T. Volk’s life On 13 July 1892, a fifth child was born to the family of the Volks who lived in a town of Neuhauzen on the Filder plateau south of Stuttgart, in the Baden-Württenberg Land2. The child was given a Christian name Otto and brought up following catholic traditions. O.T. Volk studied at gymnasiums in Rottenburg and Ehingen. After passing school- -leaving examinations, he studied in Tübingen University, Munich Technical Higher School and Munich University. Besides mathematics, O.T. Volk took courses in astronomy, history and philosophy. He attended the lectures of such famous scientists as O. Perron, K.O.H. Liebman, C.L.F. von Lindemann, A. Voss, A. Pringsheim. O.T. Volk finished studies in 1917 and passed examinations for teacher’s qualification in Stuttgart. In 1919, under the supervision of a specialist in differential geometry K. Liebman, he wrote a research work A Study of Potential Theory: The Problem of the boundary Values and defended the work in Munich Technical Higher School acquiring Doctor’s degree in Engineering. After working as teacher for a short time in Swabia, in 1919 O.T. Volk moved to Munich University to work as an assistant of C. Lindemann, who was a well- -known specialist in number theory and algebraic geometry. A year later, O.T. Volk presented another scientific work Expansion of Complex Functions of one Variable in terms of Elliptic Cylinder Functions. He was awarded Doctor’s degree in Philosophy (PhD) for this work. This scientific work enabled O.T. Volk as a young scientist to highlight the importance of computational methods. O.T. Volk was awarded Doctor’s degrees in engineering and philosophy for scientific works in the field of mathematics3. In subsequent research he concentrated on special functions and extension of the calculations of differentials by fundamental functions. On 4 March 1922, O.T. Volk completed the habilitation procedure and acquired the rank of Associate Professor in Munich University. O.T. Volk worked at Munich University until his invitation to Lithuania. 1 J.

Invitation to Kaunas On 24 September 1922, the Board of the Faculty of Mathematics and Natural Sciences of Lithuanian University considered the applications of the candidates for the university’s vacant teaching positions and approved O.T. Volk’s application, inviting him to teach at Lithuanian University4. The newly established Lithuanian University had great expectations from O.T. Volk. These expectations were fulfilled, especially in the field of mathematics. What were the key factors which shaped the decision to invite O.T. Volk to Lithuanian University? First of all, O.T. Volk was a graduate of Munich University,

  • THE-POLISH-TRACE-Ebook.Pdf
    8 THE POLISH TRACE COMPOSED FROM COMMONLY AVAILABLE SOURCES BY LECH POLKOWSKI FOR IJCRS2017 FOREWORD It is a desire of many participants of conferences to learn as much as possible about the history and culture of he visited country and place and organizers try to satisfy this desire by providing excursions into attractive places and sites. IJCRS2017 also tries to take participants to historic sites of Warmia and Mazury and to show elements of local culture. As an innovation, we propose a booklet showing some achievements of Polish scientists and cryptographers, no doubt many of them are known universally, but some probably not. What bounds all personages described here is that they all suffered due to world wars, th efirst and the second. These wars ruined their homes, made them refugees and exiles, destroyed their archives and libraries, they lost many colleagues, friends and students but were lucky enough to save lives and in some cases to begin the career overseas. We begin with the person of Jan Czochralski, world famous metallurgist, discoverer of the technique of producing metal monocrystals `the Czochralski methode’ and inventor of duraluminum and the `bahnalloy’ who started his career and obtained its heights in Germany, later returned to Poland, became a professor at the Warsaw Polytechnical, played an important role in cultural life of Warsaw, lived in Warsaw through the second world war and the Warsaw Uprising of August-September 1944 and after the war was accused of cooperating ith occupying German forces and though judged innocent was literally erased from the public life and any information about him obliterated.

Jana Czochralskiego (1885–1953), wybitnego polskiego chemika, metaloznawcy i krystalografa oraz mecenasa sztuki, poety i pisarza. Z bogatego dorobku naukowego naszkicowane zostały trzy najważniejsze jego osiągnięcia: radiomikroskop, który można uważać za pierwowzór skaningo- wego mikroskopu analizującego (SPM) nagrodzonego Nagrodą Nobla w 1986 r., stop do łożysk kolejowych znany jako „metal B”, który przyniósł Czochralskiemu sławę i bogactwo, oraz tz w. metoda Czochralskiego otrzymywania monokryszta- łów, dzięki której nazwano uczonego „ojcem współczesnej elektroniki”. Nie bez znaczenia są inne jego wynalazki, takie jak płyn do trwałej ondulacji czy „proszek od kataru z Gołąbkiem”. 1 Tekst referatu wygłoszonego na posiedzeniu Komisji Historii Nauki PAU w dniu 18 grudnia 2013 roku; opracowanie redakcyjne – Michał Kokowski.

Jednak, po ostatecznym udowodnieniu wiosną 2011 roku faktu jego współpracy z Armią Krajową, przywrócono mu dobre imię na Politechnice Warszawskiej. Słusznie więc rok 2013 został przez Sejm RP ogłoszony Rokiem Jana Czo- chralskiego.

  • On the Origin and Early History of Functional Analysis
    U.U.D.M. Project Report 2008:1 On the origin and early history of functional analysis Jens Lindström Examensarbete i matematik, 30 hp Handledare och examinator: Sten Kaijser Januari 2008 Department of Mathematics Uppsala University Abstract In this report we will study the origins and history of functional analysis up until 1918. We begin by studying ordinary and partial differential equations in the 18th and 19th century to see why there was a need to develop the concepts of functions and limits. We will see how a general theory of infinite systems of equations and determinants by Helge von Koch were used in Ivar Fredholm’s 1900 paper on the integral equation b Z ϕ(s) = f(s) + λ K(s, t)f(t)dt (1) a which resulted in a vast study of integral equations. One of the most enthusiastic followers of Fredholm and integral equation theory was David Hilbert, and we will see how he further developed the theory of integral equations and spectral theory. The concept introduced by Fredholm to study sets of transformations, or operators, made Maurice Fr´echet realize that the focus should be shifted from particular objects to sets of objects and the algebraic properties of these sets. This led him to introduce abstract spaces and we will see how he introduced the axioms that defines them. Finally, we will investigate how the Lebesgue theory of integration were used by Frigyes Riesz who was able to connect all theory of Fredholm, Fr´echet and Lebesgue to form a general theory, and a new discipline of mathematics, now known as functional analysis.

    Jan Czochralski While everybody in the semiconductor world knows the "Czochralski grown crystals", (almost) nobody knows Jan Czochralski. He was born 1885 in Kcynia, a small town in Western Poland, which then was part of Prussia; i.e. the German Advanced empire. Around 1900 he moved to Berlin, 1907 he worked as an engineer for the "Allgemeine Elektrizitäts Gesellschaft (AEG), a formerly large and famous company, defunct since about 1980 (the last remnants were swallowed by Daimler-Benz). During this time he also studied Chemistry and Metallurgy at the "Charlottenburg Technical University" and Fine arts at the Berlin university. 1917 he organized the well-equipped research laboratory of "Metallbank und Metallurgische Gesellschaft"; and he was the director of that institution until 1928. 1929 he moved back to Poland to become a Professor of Metallurgy and Metal Research in in the Chemistry Department of the Technical University in Warsaw. All the time he was involved in metallurgical research, active in many scientific organizations and advising companies and other professional entities. The second world war put an end to all this - J. Czochralski was active in supporting his co-workers and the polish underground army. After the war he returned to his native town of Kcynia were he run a small drug firm. He died in 1953 and is buried in the family tomb in Kcynia. He was quite well-known for many contributions in metallurgy, especially for this studies of the velocity of metal crystallization, and, of course, for his method of monocrystalline growth, published in 1916. "Czochralski grown crystals" are a cornerstone of modern material science, and J.

  • Theoretical Physics in Poland Before 1939*
    THEORETICAL PHYSICS IN POLAND BEFORE 1939* 1. INTRODUCTION Science, and in particular the exact sciences, is not a part of culture easily accessible to people outside a small group of experts in the given field. There is, however, at least one aspect of science - which seems not to be always duly appreciated - that can be found equally interesting and worthy of attention by both specialists and non-specialists, scientists and non-scientists. It is the history of science, of scientific institutions and of the people of science. The main goal of this work is to describe the genesis and development of theoretical physics in Poland till 1939. In the sketch presented here I begin by recalling the history of physics as a whole in Poland up to the moment when theoretical physics became a distinct field. This happened in the late 19th century. From that moment on I will focus only on theoretical physics. On its substance, I find it reasonable to split the history of physics in Poland before 1939 into the following periods: - first: up to the establishment of the Commission for National Education; - second: up to the end of the 19th century; - third: up to World War II. It is probably no coincidence that the abovementioned stages correspond roughly to the stages we find in the history of science, and of physics in particular, in the rest of the world. One may say that the first period is that of the origins of modern physics as an empirical and rational science, crowned by the works of Newton and their development in the 18th century.

  • Jan Hilary Lachs (1881-1942)
    Miłosz Pietrzyk Jan Hilary Lachs (1881–1942) e was born in Warsaw on the 15th of November 1881 into a traditional HJewish family. Up until the age of twelve, Yiddish was his only language. His father, Bernard, was a Warsaw merchant and his mother was Regina. He studied at the 2nd Government Secondary School in Warsaw and, in 1902, he obtained his school leaving certifi cate and, as a result of the low education- al standards within the Russian area of partition, he went to study abroad. Young people from the territory of the former Congress Kingdom most oft en went to study mathematics and the natural sciences in Germany and Switzer- land. Jan H. Lachs chose the Higher Technical School in Karlsruhe to do his degree. It was there that he started to study Chemistry. From 1904 to 1905 he studied at the University of Leipzig, attending the lectures of Professor Wilhelm Ostwald, one of the most eminent physical chemists of his day, the author of the fundamental textbook Lehrbuch der allgemeinen Chemie. From Leipzig he was to transfer to the university in Heidelberg, where he studied under the supervision of Ostwald’s pupil: Prof. Georg Bredig. Under his tu- torage he wrote his doctoral dissertation in chemical kinetics Adiabatische und simultane Reaktionskinetik des Diazoessigesters. His Ph.D. he obtained in 1910 and, in 1911, he went to Berlin and found employment at the Biological Laboratory of the Municipal Hospital, directed by Prof. Leonor Michaelis. In this laboratory he carried out research into the adsorption of neutral salts. He — 141 — also spent a few months of 1911 in Brunswick, where he became acquainted with the techniques and methods of research into adsorption under the di- rection of Professor Herbert Freundlich of the Brunswick Higher Technical School.

  • HARDY SPACES the Theory of Hardy Spaces Is a Cornerstone of Modern Analysis
    CAMBRIDGE STUDIES IN ADVANCED MATHEMATICS 179 Editorial Board B. BOLLOBAS,´ W. FULTON, F. KIRWAN, P. SARNAK, B. SIMON, B. TOTARO HARDY SPACES The theory of Hardy spaces is a cornerstone of modern analysis. It combines techniques from functional analysis, the theory of analytic functions, and Lesbesgue integration to create a powerful tool for many applications, pure and applied, from signal processing and Fourier analysis to maximum modulus principles and the Riemann zeta function. This book, aimed at beginning graduate students, introduces and develops the classical results on Hardy spaces and applies them to fundamental concrete problems in analysis. The results are illustrated with numerous solved exercises which also introduce subsidiary topics and recent developments. The reader’s understanding of the current state of the field, as well as its history, are further aided by engaging accounts of the key players and by the surveys of recent advances (with commented reference lists) that end each chapter. Such broad coverage makes this book the ideal source on Hardy spaces. Nikola¨ı Nikolski is Professor Emeritus at the Universite´ de Bordeaux working primarily in analysis and operator theory. He has been co-editor of four international journals and published numerous articles and research monographs. He has also supervised some 30 PhD students, including three Salem Prize winners. Professor Nikolski was elected Fellow of the AMS in 2013 and received the Prix Ampere` of the French Academy of Sciences in 2010. CAMBRIDGE STUDIES IN ADVANCED MATHEMATICS Editorial Board B.
