THABIT IBN QURRA (836-901 C.E.) Thabit Ibn Qurra Ibn Marwan al-Sabi al-Harrani was born in the year 836 C.E. 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 C.E. 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.

Zeer bedankt voor uw steun! Thabit ibn Qurra Thabit ibn Qurra abu' l'Hasan ibn Marwan al-Sabi al'Harrani (?) te Carrhae in Mesopotami« (nu Harran in Turkije 18 februari te Baghdad ) was een arabisch astronoom en wiskundige . In het Latijn wordt hij ook Thebit genoemd. Thabit, zoon van Qurra, was een telg van de Sabijnen van Harran. Deze clan aanbad de sterren en was buitengewoon ge¯nteresseerd in astronomie en wiskunde , alsmede de werken van alle bekende volkeren op dat gebied. Het is dus niet verwonderlijk dat Thabit in Baghdad ging studeren in het Huis der Wijsheid op uitnodiging van Mohammed ibn Musa ibn Shakir Thabit en zijn latere leerlingen leefden in een van de meest opwindende tijden uit de geschiedenis van de Arabische wetenschap . En niet alleen dat, hij woonde in Baghdad op het wetenschappelijke hoogtepunt van die stad. Levend op het kruispunt van de oude, Griekse wetenschap en wetenschap uit het oosten (zoals het huidige India ) en met een leenheer die de ontwikkeling van zijn interesses steunde, had Thabit toegang tot de rijkste verzameling kennis van over de hele bekende wereld en de beste onderzoeksmiddelen die er te krijgen waren. Bovendien sprak hij van huis uit Syrisch, toen nog een oost-Aramees dialect van Edessa, en sprak hij ook goed Grieks.

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.

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]):-
