  • Mathematicians and Scientists As Public Figures: Living in Ivory Towers?
    Dept. of Mathematics, Faculty of Education, Masaryk University in Brno, Dept. of Mathematics and Descriptive Geometry, VSB-Technical Univ. of Ostrava, in co-operation with the Union of Czech Mathematicians and Physicists and the Czech Society for History of Science and Technology (Brno branches) cordially invite you to an interdisciplinary workshop in the series Mathematics and Society Mathematicians and scientists as public figures: Living in Ivory Towers? 4 – 7 January 2018, Telč, Czechia In the aftermath of the global financial crisis of 2008, The Financial Times demanded that “mathematicians must get out of their ivory towers”.1 However, have they ever really been there? Is the profession of a mathematician incompatible with that of a politician, as Timothy Gowers suggests?2 Does interest in mathematics or science need to exclude involvement in the public sphere, including politics? In the history of science, there are several prominent examples of scientists who got heavily involved in politics. This was the case of Anton Pannekoek, a prominent astronomer and a socialist theorist. Albert Einstein’s involvement in the Frauenglass affair in the McCarthy era is also quite well known. An example par excellence is Dirk Jan Struik (1894–2000), who was not only involved in politics, but also sought to challenge the view of mathematics as something that gets created in an ivory tower.3 The meeting traditionally strives to support interdisciplinary debate and explore various approaches to history of mathematics. We would like to offer a view of mathematics as an indispensable part of our culture. We welcome contributed talks related to this year’s topic.

  • On Connecting Socialism and Mathematics: Dirk Struik, Jan Burgers, and Jan Tinbergen
    HISTORIA MATHEMATICA 21 (1994), 280-305 On Connecting Socialism and Mathematics: Dirk Struik, Jan Burgers, and Jan Tinbergen GERARD ALBERTS University of Nijmegen, Science & Society, P.O. Box 9108, NL-6500 HK Nijmegen, The Netherlands The Dutch mathematicians, Dirk Struik, Jan Burgers, and Jan Tinbergen, each struggled to find ways to combine their political and scientific aspirations. Although they came from similar social backgrounds and shared much the same scientific training--all were pupils of Paul Ehrenfest--their later approaches to this dilemma varied markedly. Struik's views on mathematics were the most radical, asserting that mathematical conceptions can better be understood in conjunction with larger social and intellectual processes. By contrast, of the three his mathematics changed the least under the influence of external factors. The ap- proaches taken by Burgers and Tinbergen illustrate ways in which the social context can affect a mathematician's work. Their novel ideas helped launch a new paradigm for using mathematics to address social problems, viz., the notion of mathematical modeling, which superseded the conventional approach to applied mathematics. © 1994 AcademicPress, Inc. Die holl~indischen Mathematiker Dirk Struik, Jan Burgers, und Jan Tinbergen bemi~hten sich alle drei darum, einen Weg zu finden ihre politischen und wissenschaftlichenAmbitionen miteinander zu verbinden. Obwohl sowohl ihr sozialer Hintergrund, als auch ihre wis- senschaftliche Ausbildung vergleichbar waren--alle drei waren Schiiler von Paul Ehren- fest--unterschied sich ihr sp~iteres Herangehen an diese Fragestellung. Struiks Ansichten fiber die Mathematik waren die radikalsten: Er bestand darauf, dab mathematische Ideen am besten im Zusammenhang mit dem sozialen und intellektuellen Kontext verstanden werden kfnnten.

  • Galileo, Ignoramus: Mathematics Versus Philosophy in the Scientific Revolution
    Galileo, Ignoramus: Mathematics versus Philosophy in the Scientific Revolution Viktor Blåsjö Abstract I offer a revisionist interpretation of Galileo’s role in the history of science. My overarching thesis is that Galileo lacked technical ability in mathematics, and that this can be seen as directly explaining numerous aspects of his life’s work. I suggest that it is precisely because he was bad at mathematics that Galileo was keen on experiment and empiricism, and eagerly adopted the telescope. His reliance on these hands-on modes of research was not a pioneering contribution to scientific method, but a last resort of a mind ill equipped to make a contribution on mathematical grounds. Likewise, it is precisely because he was bad at mathematics that Galileo expounded at length about basic principles of scientific method. “Those who can’t do, teach.” The vision of science articulated by Galileo was less original than is commonly assumed. It had long been taken for granted by mathematicians, who, however, did not stop to pontificate about such things in philosophical prose because they were too busy doing advanced scientific work.

  • Survey of Mathematical Problems Student Guide
    Survey of Mathematical Problems Student Guide Harold P. Boas and Susan C. Geller Texas A&M University August 2006 Copyright c 1995–2006 by Harold P. Boas and Susan C. Geller. All rights reserved. Preface Everybody talks about the weather, but nobody does anything about it. Mark Twain College mathematics instructors commonly complain that their students are poorly prepared. It is often suggested that this is a corollary of the stu- dents’ high school teachers being poorly prepared. International studies lend credence to the notion that our hard-working American school teachers would be more effective if their mathematical understanding and appreciation were enhanced and if they were empowered with creative teaching tools. At Texas A&M University, we decided to stop talking about the problem and to start doing something about it. We have been developing a Master’s program targeted at current and prospective teachers of mathematics at the secondary school level or higher. This course is a core part of the program. Our aim in the course is not to impart any specific body of knowledge, but rather to foster the students’ understanding of what mathematics is all about. The goals are: to increase students’ mathematical knowledge and skills; • to expose students to the breadth of mathematics and to many of its • interesting problems and applications; to encourage students to have fun with mathematics; • to exhibit the unity of diverse mathematical fields; • to promote students’ creativity; • to increase students’ competence with open-ended questions, with ques- • tions whose answers are not known, and with ill-posed questions; iii iv PREFACE to teach students how to read and understand mathematics; and • to give students confidence that, when their own students ask them ques- • tions, they will either know an answer or know where to look for an answer.

  • Integration by Parts: Wordplay, Abuses of Language, Andmodernmathematicaltheoryonthemove
    MICHAEL J. BARANY* Integration by Parts: Wordplay, Abuses of Language, andModernMathematicalTheoryontheMove ABSTRACT This paper accounts for the intercontinental elaboration of French mathematician Laurent Schwartz’s theory of distributions in the years immediately following World War II by tracing how mathematicians explained the theory to each other, advanced new interpretations, and reconciled existing ones. Situating distributions in mathe- maticians’ changing contexts of funding, travel, and publication, especially in con- nection with the postwar reconstruction of international science, I argue that wordplay and suggestive comparisons—often termed ‘‘abuses of language’’—helped tie com- munities of scholars together across disparate geographies and fields of study. Material limits and linguistic ambiguity, here, offered important resources for asserting *Dartmouth College, 6107 Carson Hall, Hanover, NH 03755, USA. http://mbarany.com/. [email protected].

  • Out of the Ivory Tower: the Significance of Dirk Struik As
    Historia Mathematica 29 (2002), 363–368 doi:10.1006/hmat.2002.2377 COMMEMORATIVE View metadata, citation and similar papers at core.ac.uk brought to you by CORE Out of the Ivory Tower: The Significance of Dirk Struik provided by Elsevier - Publisher Connector ∗ as Historian of Mathematics Henk J. M. Bos Mathematics Department, University of Utrecht, P.O.Box 80-010, Utrecht, 3508 TA, The Netherlands 1. CAPTIVATING The significance of Dirk Struik as historian of mathematics can be stated in very few words: for mathematicians of the past half century, all over the world, he determined the image of the history of their field. He did so through one book, his A Concise History of Mathematics [Struik 1948]. The book was first published in 1948 and from then on it found its way to the bookcases of mathematicians and mathematical institutes, was regularly updated, was translated into many languages, and was adjusted to the regional mathematical cultures of its various publics. Struik’s significance, then, was established through the written word. And he wrote much. His death offers a good opportunity1 once more to browse his famous and less famous writings. They are captivating, and they raise, as good texts do, the question of what secret enables the author to captivate his readers. Naturally the secret has to do with Struik’s personality, but also with his ideas about mathematics, its place in society, and the function of the study of its history. In this article I go in search for that secret—without finding it, obviously—hoping that along the way Struik’s significance as historian of mathematics will appear.
