    Al-qūhī: From meteorology to astronomy: Roshdi Rashed.Roshdi Rashed - 2001 - Arabic Sciences and Philosophy 11 (2):157-204.
    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 (...)

  2. Sur un théorème de géométrie sphérique: Théodose, ménélaüs, Ibn ʿirāq et Ibn hūd: Roshdi Rashed et Mohamad al-houjairi.Roshdi Rashed - 2010 - Arabic Sciences and Philosophy 20 (2):207-254.
    In his encyclopedic book, the mathematician of Saragossa, Ibn Hūd, established by an intrinsic demonstration of spherical geometry, a remarkable theorem which generalizes the proposition III.11 from Theodosius’s Spherics and integrates the propositions III.23-25 from Menelaus’s Spherics. In this paper, we study this theorem and the demonstration of Ibn Hūd. The reader will find also some established and translated texts addressing the same theme.

    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 (...)

    Al-qūhī vs. Aristotle: On motion: Roshdi Rashed.Roshdi Rashed - 1999 - Arabic Sciences and Philosophy 9 (1):7-24.
    Al-Qūhī, 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-Qūhī and to produce its mechanical presuppositions. This is the purpose of the author of this paper. Le mathématicien du X e siècle al-Qūhī (...)

    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; (...)

    Les constructions géométriques entre géométrie et algèbre: L'épître d'ab al-jd à al-brn: Roshdi Rashed.Roshdi Rashed - 2010 - Arabic Sciences and Philosophy 20 (1):1-51.
    Abū al-Jūd Muḥammad ibn al-Layth is one of the mathematicians of the 10th century who contributed most to the novel chapter on the geometric construction of the problems of solids and super-solids, and also to another chapter on solving cubic and bi-quadratic equations with the aid of conics. His works, which were significant in terms of the results they contained, are moreover important with regard to the new relations they established between algebra and geometry. Good fortune transmitted to us his (...)

    From Euclid to the second half of the 17th century, mathematicians as well as philosophers continued to raise the question of the angle of contact and, generally, of the concept of angle. This article is the first essay devoted to this subject in Arabic mathematics. It deals with Greek writings translated into Arabic on the one hand, and contributions of Arabic mathematicians on the other hand: al-Nayrīzī, Ibn al-Haytham, al-Samawʾal, al-Shīrāzī, al-Fārisī, al-Qūshjī, among others.

Les premiers travaux en ce domaine datent du VIII e siècle, et leurs auteurs, les premiers linguistes, sont précisément contemporains de l'arabisation des institutions, de l'administration, de la monnaie etc., sous le Khalife Omeyade ʿAbd al-Malik ibn Marwān. Ces premiers travaux étaient intimement liés à l'exégèse coranique, à l'orthoépie coranique, à la jurisprudence (...)

On lui doit le premier dépassement de Ptolémée en astronomie et la première critique radicale de l'ontologie aristotélicienne au nom de l'idéalisme mathématique. Au vu de son importance historique, il était urgent de publier ses œuvres encore inédites, ou non éditées de manière critique, et de les étudier de manière véritablement historique.

    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 (...)

    Une part substantielle de la réflexion philosophique est née et s'est développée aux confins de la science. Depuis l'aube de la philosophie, on ne peut faire l'économie des mathématiques, de l'astronomie, de l'optique... si l'on veut comprendre les voies empruntées par les philosophes et les modèles qu'ils ont élaborés. Cette étude examine quelques-uns de ces liens jusqu'à l'âge moderne.

    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.

    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.
