Thabit Ibn Qurra Ibn Marwan al-Sabi al-Harrani was born in the year 836 A.D. at Harran (present Turkey). As the name indicates he was basically a member of the Sabian sect, but the great Muslim mathematician Muhammad Ibn Musa Ibn Shakir, impressed by his knowledge of languages, and realising his potential for a scientific career, selected him to join the scientific group at Baghdad that was being patronised by the Abbasid Caliphs. There, he studied under the famous Banu Musa brothers. It was in this setting that Thabit contributed to several branches of science, notably mathematics, astronomy and mechanics, in addition to translating a large number of works from Greek to Arabic. Later, he was patronised by the Abbasid Caliph al-M'utadid. After a long career of scholarship, Thabit died at Baghdad in 901 A.D. Thabit's major contribution lies in mathematics and astronomy. He was instrumental in extending the concept of traditional geometry to geometrical algebra and proposed several theories that led to the development of non-Euclidean geometry, spherical trigonometry, integral calculus and real numbers. He criticised a number of theorems of Euclid's elements and proposed important improvements. He applied arithmetical terminology to geometrical quantities, and studied several aspects of conic sections, notably those of parabola and ellipse. A number of his computations aimed at determining the surfaces and volumes of different types of bodies and constitute, in fact, the processes of integral calculus, as developed later.

Extractions: 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.

Lá, estudou com os famosos irmãos Banu Musa, Thabit Ibn Qurra, contribuiu com diversos ramos da ciência, notavelmente com a matemática, astronomia e mecânica, além a traduzir um grande número trabalhos do grego para o árabe. Mais tarde, foi contratado pelo Califa Abássida Al M'utadid, após uma longa carreira, Thabit Ibn Qurra, morreu em Bagda em 901. A principal contribuição de Thabit Ibn Qurra, encontra-se na matemática e na astronomia, estendeu o conceito da geometria tradicional a álgebra geométrica e propôs diversas teorias que conduziu ao desenvolvimento da geometria, o trigonometria esférica, o cálculo integral e números reais. Criticou um número de teoremas de elementos de Euclides e propôs melhorias importantes, aplicou a terminologia aritmética às quantidades geométricas, e estudou diversos aspectos de seções cônicas.

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.

http://www-history.mcs.st-and.ac.uk/history/Mathematicians/Ibrahim.html

Extractions: 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]):-

Extractions: 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.

Extractions: Biografías Thabit Ibn Qurra Thabit Ibn Qurra Ibn Marwan al-Sabi al-Harrani nació en el año 836 C.E. en Harran, Mesopotamia (la actual Turquía). Como su nombre indica fue un miembro de la secta Sabian. La secta religiosa Sabian eran devotos de las estrellas. Siendo este el motivo de que estuvieran tan interesados en el estudio de la astronomía. La secta produjo muchos astrónomos y matemáticos, teniendo una gran vinculación con el mundo griego. Al principio adoptaron la cultura griega y era muy normal que sus miembros hablaran en griego, aunque después de la conquista de los Sabians por el Islam hablaron en árabe. Había también otra lengua que se hablaba en el sureste de Turquía, la lengua siríaca , la cual estaba basada en el dialecto arameo de Edessa. Esta era la lengua nativa de Thabit ibn Qurra, aunque él hablara también griego y árabe. Es a causa de esto, que el gran matemático musulmán Muhamammad Ibn Musa Ibn Shakir, impresionado por sus conocimientos de lenguas y dándole la posibilidad de realizar una carrera científica, lo seleccionó para que se uniera al grupo científico de Bagdad, que estaba patrocinado por el Califato Abásida, y en concreto por el califa al-M'utadid. Allí estudió matemáticas y medicina, como era normal en la época, bajo los famosos hermanos Banu Musa . Cuando terminó de estudiar volvió a Harran, pero debido a sus ideas liberales filosóficas lo llevaron a ser considerado domo "hereje". Para escapar de la persecusión, dejó Harran y se fue otra vez a Bagdad, donde continuó con su grupo.
