    ON THE WORKS OF EULER AND HIS FOLLOWERS ON SPHERICAL GEOMETRY ATHANASE PAPADOPOULOS Abstract. We review and comment on some works of Euler and his followers on spherical geometry. We start by presenting some memoirs of Euler on spherical trigonometry. We comment on Euler's use of the methods of the calculus of variations in spherical trigonometry. We then survey a series of geometrical resuls, where the stress is on the analogy between the results in spherical geometry and the corresponding results in Euclidean geometry. We elaborate on two such results. The first one, known as Lexell's Theorem (Lexell was a student of Euler), concerns the locus of the vertices of a spherical triangle with a fixed area and a given base. This is the spherical counterpart of a result in Euclid's Elements, but it is much more difficult to prove than its Euclidean analogue. The second result, due to Euler, is the spherical analogue of a generalization of a theorem of Pappus (Proposition 117 of Book VII of the Collection) on the construction of a triangle inscribed in a circle whose sides are contained in three lines that pass through three given points. Both results have many ramifications, involving several mathematicians, and we mention some of these developments. We also comment on three papers of Euler on projections of the sphere on the Euclidean plane that are related with the art of drawing geographical maps. AMS classification: 01-99 ; 53-02 ; 53-03 ; 53A05 ; 53A35. Keywords: spherical trigonometry, spherical geometry, Euler, Lexell the- orem, cartography, calculus of variations.

  • A Synoptic Overview of Selected Key People and Key Places Involved in Historical Transits of Venus
    MEETING VENUS C. Sterken, P. P. Aspaas (Eds.) The Journal of Astronomical Data 19, 1, 2013 A Synoptic Overview of Selected Key People and Key Places Involved in Historical Transits of Venus Christiaan Sterken Vrije Universiteit Brussel, Brussels, Belgium Per Pippin Aspaas University of Tromsø, Norway Abstract. This paper presents an overview of the dramatis personae et situs, or significant characters and places dealt with in this book. Several geographical and political maps, and timelines are provided as an aid to the reader. 1. Introduction The transits of Venus are landmarks in the history of science, principally because of their use in historical attempts to measure the scale of our solar system. Eight transits of Venus have occurred since the prediction of the first such event by Jo- hannes Kepler in 1629. These transits appeared in four pairs spaced by 8 years, with each pair separated by a time interval of more than one century.1 The transit pairs alternatively happen in early June and in early December. Figure 1 shows the timeline of occurrence of the events, together with the publication date of four historical works that played a crucial role in the transit of Venus science, viz., 1. In 1629, Johannes Kepler published in his De raris mirisq[ue] Anni 1631. Phaenomenis, Veneris put`a& Mercurii in Solem incursu,2 the very first pre- dictions that a transit of Mercury will occur in November 1631, followed by a transit of Venus one month later. Kepler died a year before the events. 2. Isaac Newton’s Philosophiae naturalis principia mathematica, that layed down the theoretical basis for Kepler’s laws, was published in London in 1687.

  • Transit Observations As Means to Re-Establish the Reputation of the Russian Academy of Sciences
    MEETING VENUS C. Sterken, P. P. Aspaas (Eds.) The Journal of Astronomical Data 19, 1, 2013 Transit Observations as Means to Re-establish the Reputation of the Russian Academy of Sciences Gudrun Bucher L¨owenstrasse 22, 63067 Offenbach, Germany Abstract. This paper explores how Catherine II used the worldwide attention given to observations of the transit of Venus to bring back the Russian Academy of Sciences into international recognition. Starting from the planned observations of the transit of Venus at various locations of the Russian Empire, the expeditions became more complex because naturalists were added to the astronomical expedi- tions. As the naturalists got separate instructions, their expeditions became more and more independent of the astronomers and eventually became known as the fa- mous Academic Expeditions with a tremendous output of publications. This was the second huge effort made by Russia during the eighteenth century to explore scientifically remote parts of its empire. As far as individual Venus transit expeditions are concerned, this paper focuses on those that visited places in the southern parts of the Ural Mountains and the northern shores of the Caspian Sea. 1. Russia and the 1761 transit of Venus When the calculated date of the first transit of Venus of the eighteenth century approached (June 6, 1761), the Russian Imperial Academy of Sciences (Fig. 1) was in a difficult situation. With the beginning of the reign of Elisabeth Petrovna (Tsarina 1741–1761) and her “pro-Russian” policies, open suspicion was cast on foreign scholars as possible clandestine informers of various Western powers, and the decline of the Academy began.

  • Bridges Conference Paper
    Bridges 2018 Conference Proceedings Capturing the Visual Traits of a Mathematician – On Anders Johan Lexell’s Futile Studies in Physiognomy Johan C.-E. Stén1 and Martina Reuter2 1Department of Mathematics and Statistics, University of Helsinki; [email protected] 2Department of Social Sciences and Philosophy, University of Jyväskylä; [email protected] Abstract Physiognomy is the art of interpreting a person’s psyche from his outward appearance. Today physiognomy is dismissed as unscientific, but in the 18th century, the Finnish-Swedish mathematician A. J. Lexell put the method to a serious test. On his European journey in 1780–1781, he met with the famous mathematicians and philosophers of his time and used his skill to interpret their spiritual condition. The results were not convincing, but Lexell’s vivid descriptions of his contemporaries remain an important eye-witness to the Enlightenment. Introduction Anders Johan Lexell (1740–1784) was a Swedish-Finnish mathematician and astronomer who in the years 1768–1783 worked with Leonhard Euler at the Petersburg Academy of Sciences in Russia [3]. Besides being a remarkable mathematician, Lexell also had a penchant for visual arts. He was particularly fond of the facial expressions captured in the portraits and sculptures by the great masters of the Renaissance and Baroque. In the Enlightenment, every aspect of the world was open for scientific inquiry, including human life in all its complexity. Lexell was known as a keen and patient observer of his environment and curious about the people he met. Would it be possible, he wondered, to interpret their outward appearance and facial traits in order to understand their inner, spiritual qualities? The learned collegium where he worked, with Leonhard Euler as his most notable associate, had plenty of material for the study of the outward signs of genius.

  • Call for Papers Venus Transit Conference in Tromsø
    Call for Papers Venus Transit Conference in Tromsø, 2012 A group of scholars at the University of Tromsø will host a conference on the eighteenth-century transits of Venus, in Tromsø 2-3 June 2012. The site of the conference is the Science Centre of Northern Norway, which is located at the campus of the University of Tromsø. After the conference, participants will be invited to either stay in Tromsø until the midnight 5-6 June, or take part in a “Venus Transit Tour” in Finnmark, where we will visit the historical sites Vardø, Hammerfest, and the North Cape. The post-conference program culminates with the participants observing the last transit of Venus of our century, which lends itself to be observed on the disc of the Midnight Sun in northernmost Norway, 5-6 June 2012. In Tromsø, the town’s Astronomical Association will facilitate observation of the transit, whereas the other group will observe the event in or near Vardø. After the conference, a book will be edited by the organisers, based on papers presented at the conference. Venus in transit, 8 June 2004 Photographed by David Cortner Reproduced with permission The phenomenon A transit of Venus in front of the Sun as seen from Earth is a rather rare astronomical phenomenon. The few transits that have been observed are landmarks in the global history of science. Since the invention of the telescope, only six transits have been observed, in 1639, 1761, 1769, 1874, 1882, and 2004. The last transit of our century will take place 5-6 June 2012.

  • Mathematical Monuments in Finland
    Bridges 2021 Conference Proceedings Mathematical Monuments in Finland Osmo Pekonen1, Kristóf Fenyvesi2, and Johan Stén3 1University of Jyväskylä, Finland; [email protected] 2University of Jyväskylä, Finland; [email protected] 3University of Helsinki, Finland; [email protected] Abstract With “mathematical monuments” we mean either monuments for famous mathematicians and their achievements or works of art representing mathematical objects in public places. We present a panoply of such monuments in Finland for the purposes of the mathematical tourist visiting our country. As we are interested in symbolic representations of science, we take a broad view of the notion of “monument” and take into account also some minor artefacts, such as portraits, medals and stamps, and other semiotic signs, such as street names and commemorative plates, illustrating some highlights of the history of mathematics in Finland. Introduction Some great centres of science in the world have so many monuments for past scientists and their deeds that it has been worthwhile to publish specialized guides for visitors who wish to spot them. The Hungarian couple of science historians István and Magdolna Hargittai have recently published such guidebooks about their home city Budapest [1] but also about New York [2], Moscow [3], and London [4]. Unsurprisingly, there is a similar guidebook about Paris [5]. The German couple of mathematicians Martin and Iris Grötschel have produced an analogous book focusing on mathematical sights in Berlin [6]. The Mathematical Intelligencer has a column entitled “The Mathematical Tourist” devoted to spotting of mathematical monuments. Finland holds an honourable place in the history of mathematics as a country.

  • Anders Johan Lexell's Role in the Determination of the Solar Parallax
    MEETING VENUS C. Sterken, P. P. Aspaas (Eds.) The Journal of Astronomical Data 19, 1, 2013 Anders Johan Lexell’s Role in the Determination of the Solar Parallax Johan Carl-Erik St´en Technical Research Centre of Finland, P.O.B. 1000, FI-02044 VTT Espoo Finland Per Pippin Aspaas University Library of Tromsø, University of Tromsø, NO-9037 Tromsø, Norway Abstract. Anders Johan Lexell (1740–1784) was a mathematician who gained considerable recognition for his scientific achievements during the century of En- lightenment. Born and educated in Abo/Turku˚ in the Finnish part of the Swedish Realm, he was invited as an assistant and collaborator of Leonhard Euler at the Imperial Academy of Sciences in Saint Petersburg in 1768. After Euler’s death in 1783 he inherited his mentor’s chair and became professor of mathematics at the Petersburg Academy of Sciences, but survived only a year in this office. One of Lexell’s first tasks in Saint Petersburg was to assist in the calculations involved in the Venus transit project of 1769. Under Euler’s supervision, Lexell formulated a system of modeling equations involving the whole bulk of observation data obtained from all over the world. Thus, by searching (manually) the best estimate of the parallax with respect to all available measurements made of the Venus transit si- multaneously, he anticipated later statistical modeling methods. The usual method at the time consisted of juxtaposing a pair of measurements at a time and taking a mean value of all the parallax values obtained in this way. What had started as an innocent, purely academic attempt to establish the solar parallax, soon escalated into a heated controversy of international dimensions.

We had decent weather for STEMtastic, partly cloudy for the Oasis Star Party and great weather for the Burrowing Owl Festival. What was missing at 2 of these events was club members. Tony and I were the only ones at STEMtastic and Ron Madl was the only one who came to help me for a few hours at the Burrowing Owl Festival. We did have great turnout at the Oasis Star Party. We really could have used a few others at the daytime events, even if only for an hour or two. As Ron can tell you, the scopes pretty much take care of themselves. What we need is people to answer questions and tell people about what to look for in the scopes. This Friday night we are supposed to have the public Star Party at Rotary Park in Cape Coral. If we do have bad weather, the 11th is a fallback. We also have a club star party at the Caloosahatchee Regional Park this Saturday. Currently the north side is open, so we are a go. Weather is looking good for Saturday.
