    Ibn al-haytham, Ibn sīnā, al-ṭūsī : Égalité ou congruence.Roshdi Rashed - 2019 - Arabic Sciences and Philosophy 29 (2):157-170.
    RésuméLes mathématiciens et les philosophes arabophones, comme leurs prédécesseurs grecs, ont soulevé plusieurs questions épistémologiques fondamentales. Parmi ces questions figure celle qui porte sur le concept d’égalité et sur celui de congruence des grandeurs géométriques. Mais qu'entendait-on par de tels concepts? quelle était leur relation à l'idée de mouvement? Comme les réponses à ces questions combinaient souvent des éléments métriques et d'autres, philosophiques, j'ai choisi d’étudier celles d'un mathématicien, d'un philosophe et d'un mathématicien-philosophe.

    Al-qūhī Vs. Aristotle: On Motion.Roshdi Rashed - 1999 - Arabic Sciences and Philosophy 9 (1):7.
    Al-Q, mathematician of the 10th century, examines critically two arguments in the 6th book of the Aristotelian Physics. This critic does not follow the method of the philosophers, with doctrinal amendments, but with a mathematical and experimental style. For understanding of this critical examination and its influence, it is necessary to situate it in the mathesis of al-Q and to produce its mechanical presuppositions. This is the purpose of the author of this paper.

    Al-qūhī and al-sijzī on the perfect compass and the continuous drawing of conic sections: Roshdi Rashed.Roshdi Rashed - 2003 - Arabic Sciences and Philosophy 13 (1):9-43.
    From the second half of the 10th century, mathematicians developed a new chapter in the geometry of conic sections, dealing with the theory and practice of their continuous drawing. In this article, we propose to sketch the history of this chapter in the writings of al-Qūhī and al-Sijzī. A hitherto unknown treatise by al-Sijzī - established, translated, and commented - has enabled us better to situate and understand the themes of this new research, and how it eventually approached the problem (...)

    Sur une construction du miroir parabolique par Abū al-Wafā´ al-Būzjānī.Otto Neugebauer & Roshdi Rashed - 1999 - Arabic Sciences and Philosophy 9 (2):261.
    Abzj proposed, in a fragment established and translated herein, two methods to build a parabolic mirror. The lack of demonstration, particularly for the first method, raises a difficult question of interpretation. To understand this method, O. Neugebauer used, in an unpublished article translated herein, concepts of descriptive geometry. He then eliminated the space construction used, to keep only simple geometrical considerations known by the Greeks. The second interpretation, given by R. Rashed, is based on the geometrical practices of al-Bnhzj from (...)

    Al-samaw'al, al-bīrūnī et brahmagupta: Les méthodes d'interpolation*: Roshdi Rashed.Roshdi Rashed - 1991 - Arabic Sciences and Philosophy 1 (1):101-160.
    In a manuscript which is being studied here for the first time, al-Samaw'al quotes a paragraph from al-Bīrūnī which shows that the latter knew not only of Brahmagupta's method of quadratic interpolation, but also of another Indian method. Al-Samaw'al examines these methods, as well as linear interpolation, compares them, and evaluates their respective results. He also tries to improve them. In this article the author shows that al-Bīrūnī had used four methods of interpolation, two of which were of Indian origin; (...)

    The ceLestial kinematics of Ibn al-haythamthis article is an English translation of a slightly modified version of the introduction in my most recent book, Les mathématiques infinitésimaLes du ixe au Xie siècle. Vol. V: Ibn al-haytham: Astronomie, géométrie sphérique et trigonométrie . I am grateful to J. V. field for translating this article from French into English, and for making comments that led to improvements in the text. It goes without saying that I alone am responsible for any remaining errors.: The ceLestial kinematics of Ibn al-haytham. [REVIEW]Roshdi Rashed - 2007 - Arabic Sciences and Philosophy 17 (1):7-55.
    After having reformulated optics, Ibn al-Haytham conceived of an analogous project for astronomy. This has just been revealed by an important book by the mathematician which has never been studied until now. Ibn al-Haytham's reform consists in excluding all cosmology, and in developing a systematic study of a celestial kinematics that has been completely geometrized. In turn, the realization of such a reform demanded innovative research in infinitesimal geometry. In this article, an attempt is made to present this new geometry, (...)

    Among the phenomena examined in the Meteorologica, some, although they are sublunar, are too distant to be accessible to direct study. To remedy this situation, it was necessary to develop procedures and methods which could allow observation, and above all the geometrical control of observations. The eventual result of this research was to detach the phenomenon under consideration from meteorology, and to insert it within optics or astronomy. Abū Sahl al-Qūhī, composed a treatise on shooting stars in which he carries (...)

    Like his Greek and Arab predecessors, Avicenna’s research in mathematics concerned the development of methods of exposition, proof procedures and analytical tools. But Avicenna belonged to a new era of mathematics, and the question that this paper seeks to examine is how Avicenna applied this new mathematical knowledge in his philosophy. A treatment of the subject of Avicenna and mathematics cannot, then, confine itself to generalities, important as these are, but must start from the degree of knowledge he had of (...)

    Al-Qūhī: From Meteorology to Astronomy: RÉSUMÉS.Roshdi Rashed - 2001 - Arabic Sciences and Philosophy 11 (2):153-156.
    Among the phenomena examined in the Meteorologica , some, although they are sublunar, are too distant to be accessible to direct study. To remedy this situation, it was necessary to develop procedures and methods which could allow observation, and above all the geometrical control of observations. The eventual result of this research was to detach the phenomenon under consideration from meteorology, and to insert it within optics or astronomy. Abū Sahl al-Qūhī , composed a treatise on shooting stars in which (...)

    Thābit Ibn qurra et la théorie Des parallèles: Thābit et la théorie Des parallèles.Roshdi Rashed - 2005 - Arabic Sciences and Philosophy 15 (1):9-55.
    Deux opuscules nous sont parvenus de Thābit ibn Qurra sur la théorie des parallèles. Ces deux traités sont bien connus et ont fait déjà l'objet de plusieurs commentaires et traductions. Nous pensons reprendre ici aussi bien l'édition que la traduction et le commentaire pour mieux situer la contribution de Thābit ibn Qurra après la publication récente de ses œuvres en astronomie et en mathématiques.

    Pseudo-euclide, pseudo-ptolémée et thiasos sur Les miroirs.Roshdi Rashed - 2022 - Arabic Sciences and Philosophy 32 (1):1-65.
    Among the writings devoted to the reflection of “visual” and solar rays on various mirrors, there are two that preceded many others and that occupy a central position in the history of catoptrics: one is attributed to Euclid, the other to Ptolemy. To these two names, we add a third, hitherto unknown, Thiasos. In this article, we take up the textual and conceptual history of this catoptric research tradition.
