Biography

Abu Nasr Mansur was a native of Gilan which is mentioned in The Regions of the World, a Persian geography book of 982. His family, the Banu Iraq, were rulers of Khwarazm the region adjoining the Aral Sea, and it was in this region that Abu Nasr Mansur studied and became a disciple of Abu'l-Wafa. Abu Nasr Mansur was teaching in this area when he first began his association with al-Biruni whom he taught from about 990. This began an important collaboration which was to go on for many years.

The end of the 10th century and beginning of the 11th century was a period of great unrest in the Islamic world and there were civil wars in the region in which Abu Nasr Mansur was living. Khwarazm was at this time part of the

Abu Nasr Mansur

Abu Nasr al-Mansur ibn Ali ibn Iraq (v. 960 - 1036) fut un mathématicienpersan musulman. Il est bien connu pour avoir découvert la loi des sinus.

Abu Nasr al-Mansur naquit dans la région de Gilan dans la famille royale des Afrighides du Khwarezm. Il fut donc prince dans la sphère politique. Il fut le professeur d’Al-Biruni et aussi un important collègue du mathématicien. Ensemble, ils furent à l’origine de grandes découvertes en mathématiques et se dédièrent l’un à l’autre de nombreuses œuvres.

La plupart du travail d’Abu Nasr concernait les mathématiques, mais certains de ses écrits portaient sur l’astronomie. En mathématiques, il consacra beaucoup de traités importants à la trigonométrie, développés à partir des travaux de Ptolémée. Il préserva également les écrits de Ménélaos d'Alexandrie et révisa de nombreux théorèmes des Grecs.

Il mourut dans l’actuel Afghanistan près de la ville de Ghazni.

    Abu Nasri Mansur ibn Ali ibn Iraq;

    (Persian: أبو نصر منصور بن علی بن عراق‎; c. 960 – 1036) was a Persian Muslim mathematician and astronomer. He is well known for his work with the spherical sine law.

    Abu Nasr Mansur was born in Gilan, Persia, to the ruling family of Khwarezm, the Afrighids. He was thus a prince within the political sphere. He was a student of Abu’l-Wafa and a teacher of and also an important colleague of the mathematician, Al-Biruni. Together, they were responsible for great discoveries in mathematics and dedicated many works to one another.

    Most of Abu Nasri’s work focused on math, but some of his writings were on astronomy. In mathematics, he had many important writings on trigonometry, which were developed from the writings of Ptolemy. He also preserved the writings of Menelaus of Alexandria and reworked many of the Greeks theorems.

    He died in the Ghaznavid Empire (modern-day Afghanistan) near the city of Ghazna.
