Sinan ibn Thabit ibn Qurra
Abu Said Sinan ibn Thabit ibn Qurra né en 880 environ, mort en 943 à Bagdad, (en Iraq) Sinan ibn Thabit ibn Qurra était le fils de Thabit ibn Qurra et le père de Ibrahim ibn Sinan . Bien que Sinan était extrêmement éminent en médecine ses contributions aux mathématiques étaient moins importantes mais il mérite une place dans cet archive par ses contributions aux mathématiques dans cette remarquable famille de savants. Thabit ibn Qurra , le père de Sinan , était un membre de la secte Sabienne (à Harran )qui vénérait les étoiles. Bien sur son père était motivé par l'étude de l'astronomie et la secte avait produit beaucoup d'astronomes et mathématiciens de qualité comme Thabit lui même. Sinan s'était formé en médecine, une discipline qui avec son père avaient étudié à Bagdad. Le patron de son père était le Calife, Al-Mu'tadid , un des plus grands califes Abbassit , et Sinan avait grandit dans la court où son père était astronome. Le père de Sinan, Thabit mourut en 901 le calife Al-Mu'tadid mourut l'année suivante.

Sinan ibn Thabit ibn Qurra was the son of Thabit ibn Qurra and the father of Ibrahim ibn Sinan . Although Sinan was extremely eminent in medicine his contributions to mathematics were somewhat less major but he still deserves a place in this archive as a contributor to mathematics in this remarkable family of scholars. Thabit ibn Qurra , Sinan's father, was a member of the Sabian sect. The Sabian religious sect were star worshippers from Harran. Of course being worshipers of the stars meant that there was strong motivation for the study of astronomy and the sect produced many quality astronomers and mathematicians such as Thabit himself. Sinan was trained in medicine, a topic which his father had studied in Baghdad. His father's patron was the Caliph, al-Mu'tadid, one of the greatest of the 'Abbasid caliphs, and Sinan was brought up at the court where his father held the role of court astronomer. Sinan's father Thabit died in 901 and the caliph al-Mu'tadid died the following year. Al-Mu'tadid had shown great skill in playing the various factions off against each other during his period of power but after his troops were defeated by the Qarmatians, a schismatic sect and political movement. Historians argue whether al-Mu'tadid was poisoned in a palace intrigue, but even if he was not this is an indication of the atmosphere in the court where Sinan lived. By this time Sinan was a man of about 22 years of age but, despite having great medical skills, he seems to have held no positions at this time.

Ibrahim ibn Sinan was a grandson of Thabit ibn Qurra and studied geometry and in particular tangents to circles. He also studied the apparent motion of the Sun and the geometry of shadows. There is no doubt that had he not died at the young age of thirty-eight, he would have achieved a degree of fame for his mathematical works going even beyond the opinion of Sezgin (see [5] and [6]) that he was:- ... one of the most important mathematicians in the medieval Islamic world. Perhaps his early death robbed him of the chance to make a contribution even more important than that of his famous grandfather. Ibrahim's most important work was on the quadrature of the parabola where he introduced a method of integration more general than that of Archimedes . His grandfather Thabit ibn Qurra had started to view integration in a different way to Archimedes but Ibrahim realised that al-Mahani had made improvements on what his father had achieved. To Ibrahim it was unacceptable that (see for example [1]):-

Thabit ibn Qurra was a native of Harran and a member of the Sabian sect. The Sabian religious sect were star worshippers from Harran often confused with the Mandaeans (as they are in [1]). Of course being worshipers of the stars meant that there was strong motivation for the study of astronomy and the sect produced many quality astronomers and mathematicians. The sect, with strong Greek connections, had in earlier times adopted Greek culture, and it was common for members to speak Greek although after the conquest of the Sabians by Islam, they became Arabic speakers. There was another language spoken in southeastern Turkey, namely Syriac, which was based on the East Aramaic dialect of Edessa. This language was Thabit ibn Qurra's native language, but he was fluent in both Greek and Arabic. Some accounts say that Thabit was a money changer as a young man. This is quite possible but some historians do not agree. Certainly he inherited a large family fortune and must have come from a family of high standing in the community.

THABIT IBN QURRA
Al-Sabi Thabit ibn Qurra al-Harrani né en 826 à Harran, Mésopotamie (Turquie), mort le 18 Fev 901 à Bagdad, (en Iraq)
Thabit ibn Qurra était né à Harran et était membre de la secte Sabienne qui vénérait les étoiles. Bien sur cela veut dire qu'il avait une grande motivation pour l'étude de l'astronomie et la secte avait produit beaucoup d'astronomes et mathématiciens. La secte, avec des solides relations avec les Grecs, avait adopté en premier temps la culture Grecque, et il était courant pour les membres de parler le Grec , après la conquête des Sabiens par l'Islam, ils commençaient à parler l'Arabe. Il y avait une autre langue parlée dans le sud-est de la Turquie, à savoir le Syriaque qui était la langue de la région natale de Thabit ibn Qurra , il était influencé par le Grec et l'Arabe. Quelques comptes-rendus disent que Thabit était échangeur d'argents quand il était jeune. Ce ci est plutôt possible mais quelques historiens ne sont pas d'accord. Certainement il avait hérité une grande fortune de sa famille et devait être issu d'une importante famille. Muhammad ibn Moussa ibn Shakir , qui avait visité Harran, était impressionné par le savoir de Thabit sur les langues en réalisant le potentiel du jeune homme, le persuada d'aller à Bagdad, il lui apprenait des leçons de mathématiques avec ses frères (frères Bani moussa A Bagdad Thabit recevait une formation en mathématique et en médecine, qui était courant pour les savants en ce temps. Il retourna à Harran mais sa philosophie libérale le conduisit à comparaître devant la court religieuseil devait abjurer ses ' hérésies '. Pour échapper aux persécutions il quitta Harran et avait été nommé astronome à la Court à Bagdad sous les ordres du Calife

    The Time of Al-Mas'udi
    First Half of Tenth Century The overwhelming superiority of Muslim culture continued to be felt throughout the tenth century. Indeed, it was felt more strongly than over, not only the foremost men of science were Muslims, but also because cultural influences are essentially cumulative. By the beginning, or at any rate by the middle of the century, the excellence of muslim science was already so well established, even in the West, that each new arabic work benefited to some extent by the prestige pertaining to all. To be sure, other languages, such as Latin, Greek, or Hebrew were also used by scholars, but the works written in those languages contained nothing new, and in the field of science, as in any other, when one ceases to go forward, one already begins to go backward. All the new discoveries and the new thoughts were published in arabic. strangely enough, the language of the Qur'an had thus become the international vehicle of scientific progress. The development of Muslim culture was fostere in Spain by the eighth Umayyad caliph of the west, Abd al-Rahman II, the advances of Muslim science continued to take place almost extensively in the east.

    The Time of Al-Razi
    Second Half of Ninth Century The whole ninth century was essentially a Muslim century. This more clear in the second half than of the first, since all the scientific leaders were Muslims, or at any rate were working with and for Muslims and wrote in Arabic. Cultural Background Abbasid Caliph Al-Mutawakkil (847-861) continued to protect men of science, chiefly the physicians, and he encouraged the school of translators headed by Hunain ibn Ishaq. Da ud al-Zahiri founded a new school of theology, based upon a more literal interpretation of the Qur'an; however, did not survive very long. Muslim published a new collection of traditions, arranged according to legal topics, like Bukhari's, but more theoretical. The Egyptian Dhul-Nun is generally considered the founder of Sufism, that is, of Muslim mysticism.
