Around Caspar Wesse L and the Geometric Representation of Complex Numbers
Around Caspar Wesse l and the Geometric Representation of Complex Numbers Proceedings of the Wessel Symposiu m at The Royal Danish Academy of Sciences and Letter s Copenhagen, August 1145 1998 Invited Papers Edited by Jesper Lützen Matematisk-fysiske Meddelelser 46:2 Det Kongelige Danske Videnskabernes Selska b The Royal Danish Academy of Sciences and Letters Commission Agent: C .A. Reitzels Forlag Copenhagen 2001 Abstract On March 10 1797 the Norwegian surveyor Caspar Wessel presented an essay On the Analytical Representation of Direction to The Royal Danish Academy of Sciences and Letters in which he described the geometric representa- tion of complex numbers that has since become standard . The paper was printed in the Academy's Journal two years later. In order to celebrate the 200th anniversary of this event the Academy arranged a Wessel Symposiu m on August 11-15 1998 . The contributions to the present volume are based on invited papers presented on that occasion . Their subjects range over a variety of historical themes related to Wessel and his family, to Wessel's wor k as a surveyor, to the geometric representation of complex numbers, and to the emergence of hyper-complex numbers .

The person Julius Petersen The emergence of Danish mathematics on the international scene towards the end of the nineteenth century, and the dominant role played by geometry in Danish mathematical research at that period is closely linked to the work of two mathematicians, Hieronymus Georg Zeuthen and Julius Petersen. As the two professors of mathematics at Copenhagen University they set the tone of Danish mathematics for almost three decades from the 1870’s onward. -
And Earth Sciences
The Academy and the Exact and Earth Sciences One of the greatest services the Academy has rendered to the exact sciences — a term perhaps employed too narrowly in our times for astronomy, physics, chemistry and mathematics - has been to provide economic support. At first this was only slight in financial terms but often of deci sive importance; for example, the support arranged by the tireless Academy Secretary H. C. Ørsted (1777-1851), for the Danish discoverer of the law of conservation of energy, L. A. ColdinG (1815-1888). The expression “Danish discoverer” is used because this was in fact an item of basic knowledge which was brought to light roughly simultaneously in several places in Europe. Later on it was the Carlsberg Foundation, estab lished by the brewer J. C. Jacobsen (1811-1887), that was of invaluable importance for the develop ment of the exact sciences in Denmark. Many of our most influential scientists have been members of the board of this Foundation, which is elected by the Academy, and have therefore been involved in the development of research in this country far beyond their own fields. For chemistry and the associated biological sci ences in particular, the Carlsberg Laboratory, also founded by J. C. Jacobsen in 1876, has been of great significance through the strongly interna- 39 tionally-orientated research that has been, and still is, carried on there. This also applies to the Foundation’s Institute of Biology (1932). Moreover, the Academy has been of importance in maintaining a tradition within the exact sciences in this country. This is exemplified by its publica tion of Ole Rømer’s notebook, Adversaria, in 1910, edited by Thyra Eibe and Kirstine Meyer, the former being the Danish translator of Euclid. -

The Interplay of Various Scandinavian Mathematical Journals (1859–1953) and the Road Towards Internationalization
Available online at www.sciencedirect.com ScienceDirect Historia Mathematica 45 (2018) 354–375 www.elsevier.com/locate/yhmat The interplay of various Scandinavian mathematical journals (1859–1953) and the road towards internationalization Reinhard Siegmund-Schultze University of Agder, Faculty of Engineering and Science, Gimlemoen 25a, Postboks 422, 4604 Kristiansand S, Norway Available online 20 November 2018 Abstract The merger of various Nordic mathematical journals in 1953 into Mathematica Scandinavica (for research) and into Nordisk Matematisk Tidsskrift (for the more elementary topics, from 1979 NORMAT) confirmed increasing cooperation between matured Scandinavian mathematical communities. The merger originated from practical considerations including the wish to have a critical mass for economically viable publications. The present paper presents the basic steps in the development of several Scandinavian mathematical journals from 1859, the year of the foundation of the first general mathematical journal in a Scandinavian language, the Danish Mathematisk Tidsskrift, through various converging and diverging tendencies, towards the events of the year 1953. © 2018 The Author.
