The paper presents a critical review of the iterative process used by Shams al-Dīn Muh{combining dot below)ammad al-Wābkanawī (Iran, Maragha, ca. 1270-1320) in order to compute the annular solar eclipse of 30 January 1283 from the solar and lunar parameter values obtained by Muh{combining dot below)yī al-Dīn al-Maghribī (Maragha, 1260-1274). The position of this prediction in medieval astronomy will also be discussed. Wābkanawī uses an observation as evidence for the correctness of his prediction, and his results agree to a remarkable extent with modern astronomical computations of the same eclipse. © 2013 Elsevier Inc.

Whether illustrated, described or constructed, Poncelet presented the figure as the primary form of geometrical evidence, a means of justification based in sensory perception. In Poncelet's pure geometry, the objects of geometry were emphatically representational and tangible. By contrast, though classified as analytic geometry, Julius Plücker's contemporary research treated coordinate equations as visual geometric objects-evidence-by focusing on their form and endeavouring to avoid calculations. Working from Poncelet's division between pure and analytic geometries we focus on five versions by three different geometers, of a single conic section construction written between 1817 and 1826. Despite the similarity of their results, Poncelet, Plücker, and Joseph Diaz Gergonne each addressed the problem from contrasting methodological perspectives. We examine how the figure-based distinction materialized in contemporary geometric practices, and what constituted geometric evidence when the figure was lost from view.

The goal of this paper is to provide an extensive account of Robert Leslie Ellis's largely forgotten work on philosophy of science and probability theory. On the one hand, it is suggested that both his 'idealist' renovation of the Baconian theory of induction and a 'realism' vis-à-vis natural kinds were the result of a complex dialogue with the work of William Whewell. On the other hand, it is shown to what extent the combining of these two positions contributed to Ellis's reformulation of the metaphysical foundations of traditional probability theory. This parallel is assessed with reference to the disagreement between Ellis and Whewell on the nature of (pure) mathematics and its relation to scientific knowledge. © 2013 Elsevier Inc.

© 2015 Elsevier Inc. We analyze Tartaglia's account, in 1546, of the circumstances leading to his breakthrough regarding the solution of cubic equations. He claims that he solved x 3 +rx 2 =q in 1530, well before he could handle, in 1535, equations with a linear term px (and no quadratic term). This claim is at variance with Cardano's narrative as well as with later treatments of the problem, in which the solution of equations of the latter type provides the basis for the solution of all the other types of cubic equations. We show that Tartaglia's claim is supported in his text by the use of the theory of continued proportions, that occurs as a Leitmotiv. We show that relations on continued proportions stressed by Pacioli as basic "keys" provide a simple derivation of the results given by Tartaglia, that is consistent with their chronological order. Thus, his narrative contains not only priority claims, but also proposes an account of the mathematical steps that led him to his results.

The famous French physician Jean Fernel published in 1528 in Paris the De proportionibus libri duo. This treatise belongs to the tradition of texts on proportion that follow Bradwardine's Tractatus de proportionibus seu de proportionibus velocitatum in motibus (1328). In the first book, Fernel presented a theory of ratios that is traditional but contains some distinctive features, on denominating ratios, on fractions, on irrational ratios. The second book is devoted to a theory of ratio of ratios of which I give an account in this paper. © 2013 Elsevier Inc.

Medieval algebra is distinguished from other arithmetical problem-solving techniques by its structure and technical vocabulary. In an algebraic solution one or several unknowns are named, and via operations on the unknowns the problem is transferred to the artificial setting of an equation expressed in terms of the named powers, which is then simplified and solved. In this article we examine Diophantus' Arithmetica from this perspective. We find that indeed Diophantus' method matches medieval algebra in both vocabulary and structure. Just as we see in medieval Arabic and Italian algebra, Diophantus worked out the operations expressed in the enunciation of a problem prior to setting up a polynomial equation. Further, his polynomials were regarded as aggregations with no operations present. © 2012 Elsevier Inc.

During his whole life, Leibniz attempted to elaborate a new kind of geometry devoted to relations and not to magnitudes, based on space and situation, independent of shapes and quantities, and endowed with a symbolic calculus. Such a "geometric characteristic" shares some elements with the perspective geometry: they both are geometries of situational relations, founded in a transformation preserving some invariants, using infinity, and constituting a general method of knowledge. Hence, the aim of this paper is to determine the nature of the relation between Leibniz's new geometry and the works on perspective, namely Desargues' ones. © 2013 Elsevier Inc.

© 2014 Elsevier Inc. Dénes König (1884-1944) is a Hungarian mathematician well known for his treatise on graph theory (König, 1936). When he was a student, he published two books on mathematical recreations (König, 1902, 1905a). Does his work on mathematical recreations have any relation to his work on graph theory? If yes, how are they connected? To answer these questions, we will examine his books of 1902, 1905 and 1936, and compare them with each other. We will see that the books of 1905 and 1936 include many common topics, and that the treatment of these topics is different between 1905 and 1936. Dénes König (1884-1944) est un mathématicien hongrois très connu pour son traité sur la théorie des graphes (1936). En 1902 et 1905, il a publié deux livres sur les récréations mathématiques. Ses æuvres sur les récréations mathématiques sont-elles liées à son traité sur la théorie des graphes ? Si oui, de quelle façon ? Pour répondre à ces questions, nous examinerons ses livres de 1902, 1905 et 1936, et les comparerons les uns aux autres. Nous verrons qu'à la différence de l'ouvrage de 1902, les livres de 1905 et 1936 comportent beaucoup de sujets communs, mais que les manières de traiter ces sujets diffèrent entre 1905 et 1936.

Did Heron (or his teachers) use sequences of differences to find an approximate value of the cube root of an integer? I venture a conjecture of his heuristics and a couple of possible mathematical proofs of his method. © 2013 Elsevier Inc.

The little-known Scottish mathematician William Spence was an able analyst, one of the first in Britain to be conversant with recent continental advances, and having original views. His major work on "logarithmic transcendents" gives the first detailed account of polylogarithms and related functions. A theory of algebraic equations was published just after his early death; and further essays, edited by John Herschel, were published posthumously. The most substantial of these concern an extension of his work on "logarithmic transcendents", and the general solution of linear differential and difference equations. But awareness of Spence's works was long delayed by their supposed unavailability. Spence's life, the story of his "lost" publications, and a summary of all his essays are here described. © 2013 Elsevier Inc.

Bringing the meta-mathematics of Hero of Alexandria and Claudius Ptolemy into conversation for the first time, I argue that they employ identical rhetorical strategies in the introductions to Hero's Belopoeica, Pneumatica, Metrica and Ptolemy's Almagest. They each adopt a paradigmatic argument, in which they criticize the discourses of philosophers and declare epistemological supremacy for mathematics by asserting that geometrical demonstration is indisputable. The rarity of this claim-in conjunction with the paradigmatic argument-indicates that Hero and Ptolemy participated in a single meta-mathematical tradition, which made available to them rhetoric designed to introduce, justify, and bolster the value of mathematics. Mettendo in relazione per la prima volta la meta-matematica di Erone di Alessandria con quella di Claudio Tolomeo, sostengo che questi due autori hanno impiegato strategie retoriche identiche nelle introduzioni alla Belopoeica, Pneumatica, Metrica e nell'Almagesto. Entrambi adottano un argomento paradigmatico, nel quale essi criticano i discorsi dei filosofi e dichiarano la supremazia epistemologica della matematica, asserendo che la dimostrazione geometrica è indisputabile. La rarità di questa affermazione - unita alla natura paradigmatica dell'argomento in questione - indicano che Erone e Tolomeo partecipavano ad un'unica tradizione meta-matematica che metteva a loro disposizione risorse retoriche volte a introdurre, giustificare, e promuovere il valore delle matematiche. © 2014 Elsevier Inc.

The present paper analyses the confluence of agendas held by Danish mathematicians and German refugees from Nazi oppression as they unfolded and shaped the mathematical milieu in Copenhagen during the 1930s. It does so by outlining the initiatives to aid emigrant intellectuals in Denmark and contextualises the few mathematicians who would be aided. For most of those, Denmark would be only a transit on the route to more permanent immigration, mainly in the US. Thus, their time in Copenhagen would exert only temporary influence over Danish mathematics; but as it will be argued, the impacts of their transit would be more durable both for the emigrants and for the Danish mathematical milieu. It is thus argued that the influx of emigrant mathematicians helped develop the institutional conditions of mathematics in Copenhagen in important ways that simultaneously bolstered the international outlook of Danish mathematicians. These confluences of agendas became particularly important for Danish mathematics after the war, when the networks developed during the 1930s could be drawn upon. © 2013 Elsevier Inc.

© 2017 Elsevier Inc. A number of scholars have recently maintained that a theorem in an unpublished treatise by Leibniz written in 1675 establishes a rigorous foundation for the infinitesimal calculus. I argue that this is a misinterpretation.

© 2014 Elsevier Inc. The article is devoted to Edouard Lucas's contribution to the development of mathematical recreations in the France of the post 1870 war period. Lucas's name is associated to four volumes of Récréations mathématiques published between 1882 and 1894 (the last two having been published posthumously) and to a posthumous volume L'Arithmétique amusante, which appeared in 1895. The author analyzes the context of reform of science education in relation to which mathematical recreations appeared as a means of attracting a wider public to scientific activities and inspiring young people to study science. The article brings to light how the milieu of new associations which took shape to promote science (Association Française pour l'Avancement des Sciences, Société Mathématique de France) allowed the constitution of social groups internationally connected and quite active in the promotion and development of mathematical recreations. Lastly, the article suggests that this type of mathematical activity allowed the cultivation of fields that at the time the French academic milieu perceived as marginal such as number theory and analysis situs as well as their applications.

During the several decades of the USSR's existence, Soviet mathematicians produced, at intervals, a number of volumes of survey articles which provide us with a series of 'snapshots' of Soviet mathematics down the years. In this paper, I introduce these volumes as a resource for historians of Soviet mathematics, and consider the picture they paint of the development of abstract algebra in the USSR, paying particular attention to the aspects in which these surveys differ from later, retrospective accounts of Soviet algebra.

© 2014 Elsevier Inc. This paper deals with a sub-class of recreational problems which are solved by a simple memorized rule resulting from an elementary arithmetical or algebraic solution, called proto-algebraic rules. Their recreational aspect is derived from a surprise or trick solution which is not immediately obvious to the subjects involved. Around 1560 many such problems wane from arithmetic and algebra textbooks to reappear in the eighteenth century. Several hypotheses are investigated why popular Renaissance recreational problems lost their appeal. We arrive at the conclusion that the emergence of algebra as a general problem solving method changed the scope of what is considered recreational in mathematics. Questo saggio tratta di una sottoclasse di problemi ricreativi risolti tramite memorizzazione di una semplice regola risultante da una soluzione algebraica o aritmetica, chiamata regola proto-algebraica. L'aspetto ricreativo di questi problemi deriva da una soluzione a sorpresa o da un trucco non immediatamente ovvi ai soggetti coinvolti. Intorno al 1560 svariati problemi di questo tipo sparirono dai manuali di algebra e aritmetica, per riapparire nel diciottesimo secolo. Diverse ipotesi sono vagliate sul perché problemi ricreativi popolari nel Rinascimento persero attrattività, per giungere alla conclusione che l'emergere dell'algebra come metodo generale di risoluzione di problemi cambiò la portata di ciò che era considerato ricreativo in matematica.

© 2014 Elsevier Inc. Felix Klein's Erlanger Programm (1872) has been extensively studied by historians. If the early geometrical works in Klein's career are now well-known, his links to the theory of algebraic equations before 1872 remain only evoked in the historiography. The aim of this paper is precisely to study this algebraic background, centered around particular equations arising from geometry, and participating on the elaboration of the Erlanger Programm. Another result of the investigation is to complete the historiography of algebraic equations, in which those "geometrical equations" do not appear.

The extant correspondence, consisting of ten letters from the period from 1882 to 1902, from Moritz Pasch to Felix Klein is presented together with an English translation and a short introduction. These letters provide insights into the views of Pasch and Klein regarding the role of intuition and axioms in mathematics, and also into the hiring practices of mathematics professors in the 1880s. © 2013 Elsevier Inc.

© 2014 Elsevier Inc. Akin to the mathematical recreations, John Wilkins' Mathematicall Magick (1648) elaborates the pleasant, useful and wondrous part of practical mathematics, dealing in particular with its material culture of machines and instruments. We contextualize the Mathematicall Magick by studying its institutional setting and its place within changing conceptions of art, nature, religion and mathematics. We devote special attention to the way Wilkins inscribes mechanical innovations within a discourse of wonder. Instead of treating 'wonder' as a monolithic category, we present a typology, showing that wonders were not only recreative, but were meant to inspire Wilkins' readers to new mathematical inve ntions. Conformément aux récréations mathématiques, le Mathematicall Magick (1648) de John Wilkins développe les parties plaisantes, utiles et merveilleuses des mathématiques pratiques, traitant en particulier la culture matérielle des machines et des instruments. Nous étudions le Mathematicall Magick en contexte, en explorant son cadre institutionnel et sa place dans un ensemble de conceptions en pleine transformation à l'époque - conceptions de l'art, de la nature, de la religion et des mathématiques. Nous portons une attention particulière à la manière dont les innovations mécaniques s'inscrivent dans un discours sur le merveilleux. Au lieu de traiter « le merveilleux » comme une catégorie monolithique, nous offrons une typologie, montrant que les merveilles ne sont pas seulement récréatives, mais qu'elles cherchent à inspirer à des lecteurs l'envie de créer de nouvelles inventions mathématiques.
